Pang Xiaonan leaned closer and asked Lima Xiaotian, "Why are you sure that it is a mosasaur? I mean, what evidence is it that is a mosasaur? Is there any other mutant species possible?"

Lima Oda held her hands in front of her chest, looked at the biological samples under the microscope, holding her chin with her right hand, and said: "The mutated giant lizard may indeed reach such a large size, but this environment does not seem to be an environment that can cause mutation. We all know that biological mutation is most common due to radiation, but since we entered the Bloss disc, we have not felt anything unusual in the environment here. I mean, we are just attacked by different creatures, but we have not encountered environments such as storms, volcanic eruptions, and vortexes."

Pang Xiaonan added: "Is it possible that it is a gene mutation?"

"That's a coincidence." Lima Oda frowned. "Gene mutations refer to the sudden, heritable mutation phenomenon of genomic DNA molecules. Gene mutations can occur at any time of development. Mutations refer to changes in the nucleotide sequence of the DNA genome in organisms, viruses, or chromosomals. Including even a base substitution, DNA insertion, DNA deletion or DNA repeating sequence changes. Some mutations are heritable, and mutations occurring in germ cells can be passed on to offspring. Mutations occurring in non-germ cells, i.e. somatic cells, are called somatic mutations, and are non-herited mutations. Miscellaneous DNA replication process can lead to mutations. Mutagens such as chemical and environmental factors (ultraviolet rays, etc.) can also induce mutations in organisms..."

Pang Xiaonan interrupted with a smile: "Professor Lima Xiaotian, can you please give me a simpler word? Your proper nouns are too difficult to understand. All of them are scientists, but I haven't graduated from university yet..."

It’s really embarrassing to talk to scientists without some knowledge reserves and I can’t continue talking.

"I mean," Lima Oda looked at Pang Xiaonan, "It's easy to understand that gene mutations occur in a creature, but you see, since we entered the Bloss disc, the creatures that have attacked us several times have been prehistoric beasts. This is a coincidence. It's impossible for all the creatures here to mutate, right?"

Pang Xiaonan nodded, "What you said makes sense, so why can this biological specimen be sure that it is Mosasaur?"

"When you were fighting with it, we all saw the appearance of that monster, which was a lizard-like creature. It was just that there was a little more body upgrade than the lizard. For example, it had a cheek, which was also the guarantee that it could breathe in the water for a long time." Oda Lima tried hard to recall the blurry monster images she saw through the glass window.

"Lizards are the most diverse groups among reptiles (reptiles). There are more than 4,000 species known around the world, mainly distributed in the tropical regions. The size varies greatly, from Caribbean geckos several centimeters to Komodo dragons nearly 3 to 5 meters long. Some species called snake lizards have degenerated feet, leaving only some foot marks and structures." Oda Lima felt it necessary to explain the relevant knowledge of lizards to Pang Xiaonan.

"Lizards are closely related to snakes. They have many similarities. The whole body is covered with keratinous scales derived from the epidermis. The fertile anal holes are all horizontally fissures. Males have a pair of interceptors, all of which are oviparous (or some oviparous species), square bones can move, etc.."

"Some people think that the area between lizards and snakes is that lizards have four feet, while snakes have no feet. A pair of claw-shaped hind limbs can be found on both sides of the fertile anal hole of some python snakes; while snake lizards cannot even find the foot marks in their appearance, and people often mistake them for snakes."

Lima Oda looked at Pang Xiaonan: "In terms of its easy-to-identify features in appearance, the difference between lizards and snakes is: 1.|The left and right halves of the lizard's mandible are combined with bone seams, and cannot move, and the mouth cannot be widened. The left and right halves of the snake's mandible are connected by ligaments and can be opened and opened. This is one of the reasons why the snake's mouth can be opened very much. 2.|Lizards generally have limbs. Even if the limbs are degenerated and have no existing species, there must be residuals of the forelimb belt (shoulder straps) in their bodies. Snakes generally do not have limbs. Even if there are species remaining with hind limbs, there is no residuals of the forelimb belt in their bodies. 3.|Lizards mostly have movable upper and lower eyelids, and the eyes can be opened and closed freely. The upper and lower eyelids of the snake heal into a transparent film, covering the outside of the eyes, and it looks like a snake

The eyes are always open.4.|Most species of lizards have wide and thick tongues. The snake's tongue is very slender, with a deep fork at the front of the sheath. It often stretches and shrinks through the gap at the front of the mouth to collect "odor" molecules from the outside (mainly food) and sends them to the hoe-nasal device to produce a sense of smell.5.|Lizards generally have external ear holes. Even if they do not, the place where the eardrum is located can be seen from the outside. Snakes do not have external ears or eardrums, so there is no trace of auditory organs on the outside.6.|Lizards have long tails, generally about (or only slightly shorter than) the length of the head, or 2-3 times the length of the head. The snake's tail is relatively short, from 1/2 to 1/4 of the body length (that is, the tail length accounts for 1/3-1/5 of the total length).

"If you compare the differences between lizards and snakes in detail, you can also give some more examples. Although they have many differences, in terms of the evolution of organic structures during the development of the animal kingdom, they are both in the same development stage and very similar. Therefore, almost all taxonomists in the world currently place them in the order of the scaly under the Cerpillars, which are different from two different suborders." As a paleontologist, Lima Oda has very detailed research on ancient races such as lizards and snakes.

"What are the specific characteristics of the lizard's appearance?" Pang Xiaonan listened with relish, hoping to learn more.

Lima Oda thought for a while and listed the appearance characteristics of several lizards: "The body of lizards is generally divided into four parts: head, neck, trunk and tail. The body skin of lizards is leathery scales, and some species also have small bone plates under the scales, such as stone dragons, snake lizards, etc. Lizards have small teeth, and the shape and length of the tongue vary according to the breed. The eyes are more developed, and some species have cranial top eyes. Except for most geckos, the eyelids are mostly able to move, and the eyes of cave-type eyes are mostly hidden under the skin. The ears of lizards are mostly exposed and the eardrum is well developed. The left and right maches are combined with bone seams, so the mouth cannot be opened too large. The lizards have slender bodies, thick and developed hind limbs, and the bottom of the soles of the feet have membranes that can be opened or closed. When it runs on the water surface, these membranes will be opened, which greatly increases the contact area between the soles of the feet and the water surface."

"So did the mosasaur just now have these characteristics?" Pang Xiaonan still didn't believe there was such a big lizard.

"The basic characteristics are all available," Oda Lima pointed to the biological sample, "for example, this epidermis is almost 100% consistent with the leather scales of the lizard."

"It seems that we have really reached the prehistoric world." Pang Xiaonan's eyes drifted to the sea through the glass windows of the cabin.

Pang Xiaonan returned to the deck. Although it was already dawn, danger was everywhere. He wanted to make sure that the surrounding environment was foolproof. Besides, Li Yisi had been guarding for several hours and wanted to let him go back and rest.

Booktonlin had arranged the staff on duty, and there were four people left on the deck. Pang Xiaonan walked over and said to Booktonlin: "Captain, I'm back."

Booktonlin turned his head to look at Pang Xiaonan, showed a rare smile, and said, "You have worked hard all night, so you might as well go back to the cabin to have a rest."

Pang Xiaonan smiled and shook his head, saying, "I can rest on the deck."

"Are you sure?" Booktonlin patted Pang Xiaonan's shoulder, "It's just that I can rest on the deck, but it's not as comfortable as I sleep on the bed. Listen to me, go and have a rest."

"Captain, I can better monitor the dangers around me on the deck," Pang Xiaonan pointed to the sea in the distance, "Maybe there is a greater danger waiting for us somewhere."

Booktonlin frowned. What Pang Xiaonan said made sense. Although the previous few waves of dangers have passed, unknown dangers may come at any time.

"Okay, you can rest on the deck, thank you for your hard work." Booktonlin patted Pang Xiaonan's shoulder again, turned around and walked back to the cockpit.

The first mate Buenosky had returned to the rudder. Booktonlin closed the hatch door and asked, "We have not deviated from our direction, right?"

"Don't worry, captain, I've been calibrating the direction and you won't go wrong." Buenoski grabbed the steering wheel tightly, looking ahead without blinking.

"Have you had a good rest?" Booktonlin was more worried about Buenosky's mental state.

"I've had a good rest, and I'm in great spirits now." Buenoski put a bright smile on Booktonlin.

"Why haven't you seen the land yet? Is there no land in this Bros disc?" Booktonlin looked at the vast sea and said to himself.

"Captain, go and have a rest." A sentence suddenly appeared in Buenoski's mouth.

"No, this sea is too dangerous, I have to stay here." Booktonlin pinched his sore eyes with two fingers. His nerves were too tense that day and night.

"You haven't had a rest for a long time, and your body will collapse at that time," Buenosky turned his head to look at Booktonlin, holding the steering wheel like iron pliers. "The bad spirit will affect your judgment at that time."

Buenosky is right. A commander must always keep a clear mind, but if he doesn't rest for a long time, his mind will be slow and he will be prone to errors.

"Well...I admit what you said makes sense," Booktonlin shook his head, his head was now covered in mucus. "Maybe I really should go and have a rest."

"Don't worry, I'm staring here," Buenoski made a quick move and pointed at Pang Xiaonan on the deck. "That guy is a little trick. Ordinary animals are not his opponents. Besides, we have strong firepower support."

Buenosky happened to see the final scene of Pang Xiaonan fighting with Mosado, and was shocked by Pang Xiaonan. And he was right. It was daytime now. If there was danger approaching, it would be much safer than at night. The Black Mamba Guards were more confident in dealing with it.

"Okay, I'll go and have a rest, and I'll leave it to you. If there is any situation, please call me immediately." Booktonlin finally dragged his tired body back to his sleeping room, without taking off his clothes, and lay down on the boat and closed his eyelids.

Pang Xiaonan's physical strength recovered quickly. He found a comfortable position to sit on the deck and began to absorb spiritual energy again. After fighting with Mosasaur, he consumed a lot of physical strength. He just ate a compressed biscuit and had something in his stomach, but he still had to replenish some spiritual power in case of fighting with unknown monsters next time.

Everyone knows that Pang Xiaonan can sense the dangers nearby and acts as the "Bloss Flower" radar, so no one disturbs him and lets him quietly close his eyes and rest.

Sniper Wu Yongqiang stared at the scope. He stood directly in front of the ship's side on the deck, constantly changing the direction of the sniper rifle to ensure that there are no dangerous creatures around him approaching.

Nandegrad and Zhao Guifei chatted in a low voice. Nandegrad said: "Pang Xiaonan is really a magical guy. When he just came out of the sea, I carefully checked his body. There was no wound at all. Fighting with such a big animal, there was no wound at all. It was amazing."

When Mosasaur bit the "Bloss Flower", he woke everyone up. All the members of the Black Mamba Guard resting in the cabin ran to the deck and were ready for fire support at any time, so they all saw the scene of Pang Xiaonan fighting with Mosasaur.

"Yes, to be honest, I don't even have the courage to jump down." Zhao Guifei occasionally held the scope and looked at the sea surface in front of him, ensuring that no unknown creatures were approaching.

"To be honest, I didn't like him at the beginning." Nandegrad leaned on the side of the ship and pressed his shoulders. "I see that he is so young, and how high his martial arts are, it's really a mistake."

"I think Pang Xiaonan is unfathomable," Zhao Guifei imitated Nandegrad's appearance and put his feet on the side of the boat, pressing his legs. "You think, Pang Xiaonan is so young and still a student, so he joined our Black Mamba. If he doesn't have extraordinary skills, I think Black Mamba is not a place to keep idle people, and the bosses are not so kind to find someone to make a living."

"Yes, it seems that the chief instructor has a good vision." Nandegrad moved his shoulders left and right.

"You mean that Pang Xiaonan was personally selected by the chief instructor?" Zhao Guifei looked at Nandegrad curiously. According to his understanding, the members of the Black Mamba have gone through countless rounds of screening before they can officially join, and most of them register by themselves, that is, through the recruitment interview process.

"Yes, Chief Instructor Bei Dajun personally recruited it." Nandegrad is the old man of Black Mamba, and he can learn a lot of internal news at the first time.

"This is not simple," Zhao Guifei knew the strictness of Bei Dajun. "It should be not simple for those who can be valued by the chief instructor. No wonder Pang Xiaonan has such high martial arts skills."

"I also heard that Pang Xiaonan's martial arts skills are comparable to those of the chief instructor." Nandegrad threw a smile at Zhao Guifei.

Nandegrad and Zhao Guifei have worked together many times, so they are very familiar friends and can entrust their lives to each other's comrades.

"So amazing?" Zhao Guifei's eyes were full of incredibleness, but soon became dull again. "In fact, judging from the scene where he just fought with monsters, it was not surprising that the martial arts skills of the chief instructor were similar to those of the chief instructor."

Bei Dajun has fought with many subordinates on the training ground of Hei Mamba, but has never lost. This is one of the reasons why Hei Mamba members believe in him.

"Yes, I didn't believe it before. When did the chief instructor lose? Otherwise, how could he become the chief instructor?" Although Nandegrad is a medical officer, he also has to participate in the training of the black Mamba in case of emergency. "But after watching Pang Xiaonan's real fight scene, I believe he should be the opponent of the chief instructor."

"The chief instructor won't recruit Pang Xiaonan because he couldn't defeat him, right?" Zhao Guifei thought about the process of Pang Xiaonan entering the Black Mamba. First, Bei Dajun and Pang Xiaonan had a dispute, and then the two fought and didn't know each other. Bei Dajun found that Pang Xiaonan was just as good as his young age, so the hero cherished the hero and recruited Pang Xiaonan into the Black Mamba at any cost...

"I think it's not just because of his good martial arts skills," Nandegrad turned to look at Pang Xiaonan, who was meditating. "Didn't you pay attention to his temperament?"

"Temperament? What temperament? As a combat unit, the most important temperament is murderous aura, right?" Zhao Guifei was a little confused, not knowing what he sold in Nandegrad gourd.

"Leadership temperament," Nandegrad stretched out his right hand and pointed at Pang Xiaonan, "Didn't you find that he is very independent? And his leadership temperament makes people feel very comfortable." Nandegrad turned his head and looked at Zhao Guifei, "I mean, our current captain, his leadership temperament is very majestic, but I just think that Pang Xiaonan's leadership temperament makes people involuntarily want to do things with him."

"You said this, it's really interesting." Zhao Guifei took a deep breath of fresh air, "As soon as he took action, we would always provide him with support. And he really deserves his life. If it weren't for him, we would have been buried at the bottom of the sea."

Nandegrad pressed his elbows on the side of the ship, leaned against the side of the ship, nodded, and said, "Indeed, only one leader who charges is the real leader. This boy is becoming more and more popular."

"Look, look!" At this time, Wu Yongqiang pointed at the front and shouted.

Nandegrad and Zhao Guifei looked in the direction Wu Yongqiang pointed at the same time.

It's land!

The first mate Buenosky in the cockpit also saw that he stood taller than others and saw a farther distance. He was a group of reefs. Behind the reefs was a relatively large land. The island was a specific size, and the ship could see clearly.

Buenosky looked at the instrument and the pointers were still on the "0" scale of the dial, indicating that it was still inside the Bloss disc.

Buenoski's eyes were full of excitement. After driving for so long, he finally saw the land.

The few people on the deck were also excited. After experiencing several major dangers, this luxurious scientific expedition team was finally about to board the land in the Bros disc.

"Nandegler, go and call the captain and report to him that we have seen land." Buenoski pressed down on the Bluetooth headset and arranged the division of labor of his teammates. "Wu Yongqiang and Zhao Guifei, continue to observe and see if there is any danger nearby."

Although I saw the land, the danger still cannot be lifted. Perhaps there are more dangers in this waters close to the land. At any time, the Black Mamba Guard cannot relax its vigilance. This is also the consensus of all members of the Black Mamba Guard.

Pang Xiaonan also opened his eyes. Although he did not feel the significant fluctuations in his aura, he could clearly feel that the purity of the spiritual energy had changed, which was purer than before. Then there was only one possibility, that is, the environment here was no longer the previous sea area.

Amid the shouts of his teammates, he knew that he had seen the land, so he walked towards the side of the ship and carefully observed the scene in front of him.

Reefs of all sizes are distributed on the sea surface close to the land. They do not look like coral reefs, but are composed of rocks. Behind the reefs, large pieces of land can be vaguely seen.

Pang Xiaonan took off Wu Yongqiang's Bluetooth headset, put it on his ear, pressed the switch and said, "Primary, stop the boat first, I'll check it out to see if there is any danger."

The "Bloss Flower" is almost approaching the reef group, and Buenosky is also hesitating whether to continue to bloom. If you don't understand the situation under the sea, once you hit the reef, you will be in a dilemma.

To figure out the situation under the water, someone must dive into the sea to see it. This is a very dangerous thing, and it is perfect for Pang Xiaonan to do this. Pang Xiaonan has already proposed it himself, so that would be better.
Chapter completed!
