The Carboniferous Period was the age of giant insects.
Insects dominate the world.
In fact, long before the Devonian and Silurian periods, that is, in the late Ordovician period, and long before the first mass extinction, there were already myriapod arthropods that relied on their hard exoskeletons and strong legs to briefly survive.
Set foot on the earth.
It's just that these pioneer reptiles were too lonely on the earth, so they returned to the water. They waited until plants also set foot on the earth in the Silurian Period, and then immediately returned to the terrestrial paradise without natural enemies.
Arthropods spent three eras of accumulation and development, and finally made themselves the masters of heaven and earth in the Carboniferous Period.
In the Carboniferous Period, which lasted for nearly 60 million years, there were millipedes nearly three meters long, dragonflies with a wingspan of one meter, and scorpions nearly one meter long.
These large arthropods were active in large, sun-blocking forests composed of ferns, seed plants that appeared in the middle Carboniferous period, and gymnosperms that appeared in the late Carboniferous period.
As you see the earth, almost every inch is covered with green plants.
After that, arthropods and plants joined hands to enter the more prosperous Permian Period, which was also the last period of the Paleozoic Era and ushered in unprecedented prosperity.
If nothing unexpected happens, a certain branch of arthropods should have evolved a more complex and intelligent brain and become an intelligent civilization.
But accidents always happen as expected.
At the end of the Permian period, the third mass extinction occurred.
This is a cruel threshold that stands in front of more than 96% of all life on earth, and cannot cross it.
This is also the most serious and ruthless mass extinction in the history of the earth.
This is the Siberian Traps event.
In this event, the world was turned upside down. There were meteorite impacts, volcanic eruptions caused by geological changes, and sunspot explosions. The combination of these multiple factors turned into a reaper of death.
In the suffering of life, time enters the Triassic Period.
The survivors stood up again.
The age of reptiles has begun.
Dinosaurs became the masters of the earth.
The true ancestors of mankind have also appeared, but at this time, the ancestors are still being hunted and threatened by dinosaurs.
At this time, the human ancestors were not ancient apes, but a branch of reptiles called monopsids, and they were oviparous animals, not mammals.
The ancestors of this line also joined the competition for dominance over nature, but unfortunately, dinosaurs that were taller, had larger food appetites, and had stronger athletic abilities were the first to take the lead and adapted to the new environment of the Triassic.
And became the master of the earth, and then regarded all other animals and plants lower than itself in the food chain as food sources.
The ancestors of mankind had no ability to resist at all, so they could only do the opposite and develop in the direction of improving their survival ability as much as possible.
During tens of millions of years of iterative evolution, the human ancestors who survived but never became extinct became smaller and smaller, even as big as today's cats.
Moreover, human ancestors also changed their living habits from diurnal animals to nocturnal animals.
In order to survive better, human ancestors continued to enhance their ability to perceive the outside world through iterative evolution, and acquired stronger senses of smell, taste, and hearing.
In order to process more and more complex and external information, human ancestors began to have a cerebral cortex composed of neuron cells with stronger computing power on the surface of the brain.
The emergence of the cerebral cortex can be said to be an important milestone in the history of biology.
This means that at that time, our ancestors, who lived day and night, lived in caves, and were busy avoiding dinosaurs all day long, had a very difficult time surviving, but were driven by the desire to survive and took the lead in embarking on the path to the birth of wisdom.
Time flies, human ancestors and dinosaurs walked through the Triassic Period together, survived the fourth mass extinction at the end of the Triassic Period, and then passed through the Jurassic and Cretaceous periods.
As time went on to 66 million years ago, a new milestone event occurred.
The common ancestor of all mammals, including humans, is the line of reptiles that first gave birth to the cerebral cortex. It seems that they finally got tired of the process of first laying eggs and then hatching, and evolved a reproductive method that skips egg laying and hatching.
The eggs develop to a certain extent in the female body before giving birth. The cubs are capable of movement from birth.
The birth of mammals.
But at this time, although mammals have higher IQs, they still have no chance to seize dominance of the earth.
The three major branches of land dinosaurs, mosasaurs and pterosaurs, ruled the earth, sky and sea respectively.
The ancestors of smaller mammals still could only lie in bed during the day and emerge at night, struggling to hibernate.
But another million years passed, and 65 million years ago, the fifth mass extinction occurred.
This is a well-documented asteroid impact event on the Earth, and a clear conclusion has been drawn.
Zhou You did indeed see the huge fireball falling from the sky.
After the impact, the earth once again entered eternal night.
Due to the rapid deterioration of the external environment, the dominance of the dinosaur family was instantly wiped out.
Especially the larger the dinosaurs and the higher their status in the food chain, the faster they died and the more complete their demise.
Nowadays, smaller insect arthropods have easily withstood this disaster, relying on the corpses of dinosaurs.
While insects were feasting, human ancestors, mammals, who had survived the asteroid impact by hiding in caves, were left behind by the mantises and cicadas, and by feeding on insects, they also lived a relatively comfortable life.
After the impact of the fifth mass extinction, mammals officially stood at the center of the historical stage.
The human ancestors at this time were actually only about 15 centimeters in length, which is similar to today's shrunken humans.
56 million years ago, Astra monkeys, the ancestors of primates, appeared.
23 million years ago, great apes appeared.
Then, time fast forwards to modern times, and ape-men appear.
As a bystander, Zhou You witnessed the changes over the years and also saw the epic story of life.
With an incredible perspective, he saw every major mutation in biological genes over billions of years.
He saw mass extinction after mass extinction.
His mind inevitably fell into such a grand disaster scenario.
Inevitably, he begins to become more indifferent and heartless.
Perhaps for every individual, a person's life and death are unparalleled events.
But if you extend the time to the entire history of biology and expand the space to the entire earth, the life and death of even a behemoth like a blue whale or a giant land monster like a brontosaurus is not worth mentioning.
Zhou You witnessed with his own eyes how life on earth has evolved from the most basic organic molecule through countless generations of iterations, and finally slowly transformed into the most complex and all-encompassing human being on the entire earth so far, but also has the greatest life potential.
In a sense, every individual among today's human beings has in his body a treasure trove of mysteries that spans more than three billion years of life.
Zhou You spent one night and one dream reading the entire book, then woke up with a start and sat up suddenly.
The moment he opened his eyes, he saw Luo Xun busy around him.
Hearing his movements, Luo Xun quickly turned her head and said happily: "Boss, you're awake!"
Zhou You shook his head, "Well, I'm awake. How was the situation last night?"
Luo Xun waved his hand, "Hey, what else could happen? We are trying to conquer the top of Mount Tai. Boss, you cut off their leader. As long as there is no threat of arson, those miscellaneous fish are nothing."
Ah, they will all be destroyed in a matter of minutes!”
Zhou You nodded when he heard the words, feeling relieved.
Luo Xun started talking over there, getting more and more energetic as she spoke, "It's a bit ridiculous to say that some people are simply guilty, but they actually imitate the hostages and want to sneak into the team. We haven't even waited for the rescued hostages.
To identify them, other gangsters who had been captured alive and were waiting to be executed jumped out one after another and took the initiative to identify their accomplices."
"But there are also gangsters who deliberately identify random people in order to confuse the public and kill a few more people. Among the hostages, there are even people who deliberately identify other people in order to frame others. The reason is that the other party's hands were shaking when they were distributing food, and they gave him less.
A small piece of potato! In short, what stands out is that once people are safe, they can do all kinds of weird things. The main focus is biodiversity!"
It seems that after spending a long time with people like Zhou You Shenling, Luo Xun's speech has become "technical" now.
What Zhou You cared about was the result, so he just asked casually: "Did someone get killed by mistake?"
Luo Xun shook his head, "Currently, only those who are not controversial have been executed, but there are still some controversial ones who are only temporarily detained and need to be carefully interrogated. Of course, what Brother Tao said is that it is best to wait until you wake up before making a decision."
Just as he was talking, Luo Xun walked up to Zhou You with the ointment and said, "Okay, don't move around for now, lie down. Although your recovery ability is exaggerated, you suffered too many injuries yesterday, even if the skin on your body is injured,
The external injuries are no longer visible, but the bone fractures revealed by the X-ray are still not healed. Fortunately, your internal bleeding has stopped on its own, so it’s nothing serious.”
"You fell into coma just in time yesterday. If you hold on for a while longer, the nutrients in your body will be sucked dry, and then you will start to break down muscle fibers to provide energy for self-healing. You don't know, after last night we
When your body is at its peak, seven or eight tubes are inserted to deliver nutrient solution to you at the same time, otherwise it will really be impossible to keep up with your consumption."
After listening to what Luo Xun said, Zhou You was in the mood to take a look at himself.
very good.
Just as Luo Xun said, after a night of dreaming, all the injuries on Zhou You's body had indeed disappeared without a trace.
Not only that, if it is a normal person, after suffering a serious surface injury and then waking up, the skin color at the scar location will definitely show an obvious color difference from the skin color at other parts.
People with scarred constitutions can hardly wait for the discoloration to disappear throughout their lives.
Even for people who don't have scars, it will take at least several years for them to fade away.
But at this time, Zhou You's body could not see any color difference at all, and it looked as delicate and fair as a baby's skin.
Zhou You felt embarrassed when he looked at it. He felt that it was really embarrassing for a man like him to have such a stagnant white jade-like appearance.
etc!
Zhou You finally realized something. He was completely naked at this moment, with not a single piece of cloth at all!
"Okay, stop looking. Everyone knows you have good skin. Don't be narcissistic."
When Zhou You was in a daze, Luo Xun suddenly pushed him.
Caught off guard, Zhou You fell backwards, but subconsciously wanted to pull up the quilt next to him to cover himself.
Luo Xun, who was about to give him medicine, was stunned and said angrily: "Hey, boss, what are you hiding? The first day I met you, I saw you naked, and your crotch was full of
I cleaned it up for you. From last night to now when you passed out, weren't it me and Shen Ling who wiped your body together? It's really a bit magical to say that when you broke through for the first time,
It’s the normal way of excretion.”
"But last night, every pore on your body was secreting all kinds of weird and sticky stuff. It was like a snail. We couldn't wipe it away. Also, you know that we gave you a total of
How much nutrient solution did you put in? It’s almost catching up with your own weight! Okay, bring it to you! This is not the first time a big girl has got on the sedan chair. There is no need to hide it, but don’t hide your illness and avoid medical treatment."
Yes, it is said that those who are close to vermillion are red and those who are close to ink are black. Luo Xun was obviously poisoned by Bai Youyou, who was particularly good at talking, and developed in the direction of the wild school.
However, what Luo Xun said made sense, and Zhou You actually lay down calmly.
Luo Xun first made a simple inspection of the injured bone area on Zhou You's body, and while gently squeezing it, asked if it hurt.
About an hour and a half ago, Dr. Lin Ziying used the self-improved micro X-ray equipment to take a bone X-ray photo of Zhou You, confirming that although the bone fracture on his body had improved significantly, it was indeed not healed yet.
Now something strange happened, no matter where Luo Xun pinched, Zhou You felt no pain at all.
Then Luo Xun simply pinched Zhou You's shoulder.
Zhou You felt the pain and was sure that he had not lost his sense of pain.
The reason why those bone injuries no longer hurt is because they have fully recovered.
Luo Xun scratched her head, "It's strange. According to the recovery speed you showed before, it will take at least three or four days for these crippling injuries to heal. Why are you suddenly... healed?
?”
Zhou You fell into silence.
He himself actually felt very confused.
This recovery speed is indeed somewhat abnormal.
At this time, he recalled in his mind the scenes he had seen in his dreams and the iterations and changes of the animals he had seen.
In his mind, he remembered the genes of an animal, which was a mollusk, and its representative was a sea slug.
Sea slugs have incredible regenerative abilities.
Even if its body is eaten by other animals, as long as there is still a head left, it can heal the wound and regrow the heart and the entire body without even needing a heart.
Not only that, the sea slug's head can also absorb the chloroplasts of algae, allowing the chloroplasts to enter its body and become a part of itself, and use photosynthesis to provide itself with energy and nutrients.
Zhou You subconsciously felt that, based on Luo Xun's previous description, his regeneration ability had probably risen from the level of the second transcendental awakening to a level similar to that of a sea slug.
"Luo Xun, please bring me a scalpel."
"What do you want to do?"
"Test it."
After three minutes, Zhou You adjusted his breathing steadily, and then drew the scalpel slightly hard on the palm of his hand.
A wound about two millimeters deep appeared.
It seems like red blood wants to flow out.
But just a tiny bit of red appeared on the surface of the wound, and the bleeding stopped immediately.
An even stranger thing happened. Zhou You watched as strange mucus began to secrete from the wound section, and he felt a numb and itchy feeling coming from the palm of his hand.
Immediately afterwards, he saw that this wound, which was not too shallow for today's humans, was "suturing" itself from both ends to the middle like a zipper.
After that, the numbing and itching feeling disappeared.
Zhou You put down the scalpel and rubbed the palm of his left hand with his right hand.
After the mucus was taken away, the palms were still visible, and even the palm prints had completely returned to their original appearance.
Healed again!
This entire recovery process probably takes less than two seconds.
Zhou You finally confirmed that this was the third time he had awakened beyond his limit.
This matter must be related to the dream I experienced last night.
So what exactly is this third awakening ability?
Is it just an enhanced version of self-healing?
Last night I read the entire history of life on earth in a dream. What is the meaning behind it?
