Chapter 17 Arithmetic Sequences

Li Lvyan still disapproved, "You have just seen that even if modern bullets are powerful, when faced with fine iron, especially this kind of magic weapon that was used more than a thousand years ago, it is only disappointing. The bullets you shoot are only

It can make it shift slightly, and on the basis of this shift, one needs to have absolute design skills, judgment and precise marksmanship. Only you can do it here, even if we are really powerful and have the ability to float on water.

Even if you pass, you won't be able to pass."

Zhuo Ziyan was startled when he heard this, and sat down again quietly, seeming to agree with Li Luyi's words.

Xu Weihang shook his head, stood up while pointing out Jiang Shan's passionate words, and introduced himself eloquently. After being kicked by Fu Gua, he stopped talking nonsense, "Since the sky and the ground can't pass, we can go directly under the bridge.

"

Everyone was curious and said, "It's interesting."

"Although mercury is indeed poisonous and will be harmful if inhaled, we are just in the past and are not in it for a long time. Didn't Li Green Ant just say that we won't be poisoned easily here?"

Seeing everyone's eyes looking over, Li Lvyan nodded truthfully, "Yes, the tops of our heads are not blocked. Although the two cliffs are high, we can still breathe air. But if we really come into close contact, it will take a long time."

There will still be discomfort, but as long as we can control it and get it over in a short period of time, it should be fine."

After receiving Li Luyi's approval, Xu Weihang became even more arrogant and quickly talked about his unique insights.

"So, how do you get there?"

Zhuo Ziyan asked lightly, which immediately made Xu Weihang's face turn red.

"What?"

"I said, since you came up with this solution, you must have solved the other problem. How do you get across the mercury pool?"

Xu Weihang was asked a question out of the blue by Zhuo Ziyan. He was like a mouse whose tail was stepped on by a cat. He muttered, "Is this - this question -"

Wo Gua saw the opportunity and teased, "This question may not be solved until the cooked duck flies away, or the day lily is cooled, or the child soaks in soy sauce, or the big nose runs into the mouth and knows how to get rid of it."

Work out a perfect plan to tell us how to cross the river."

"You, you - I can't think of it, can you think of it?"

Wo Gua's eyebrows were dancing with joy, "I'm not a coward like you. I can naturally come up with military strategies as a handsome man."

Li Luyi also looked at the confident Wo Gua in surprise. He looked around, then focused on a few points, and said to Xu Weihang, "Boy, watch it!"

But when he saw Wo Gua using his hands and feet to climb onto the big bronze cauldron, as if he was planning to take advantage of the cauldron, Li Lvyan immediately understood Wo Gua's intention and quickly pulled him down. Wo Gua looked at him in confusion.

Li Green Ant.

"Wo Gua, I know what you mean. You want to use that big cauldron as a boat. Can we row the cauldron across the mercury pond?"

Wo Gua looked at Li Luyi with surprise and said, "What? You also think this method is genius, don't you?"

"On the contrary, Wogua, this idea is worse than anything you have thought of before."

"Bronze is an alloy of copper, tin, and lead, with a density between 8 and 9 g/cm3, while the density of mercury is 13.6 g/cm3. At normal temperature of about 24°C, the solubility of metals in mercury, copper accounts for 0.0032%, and lead accounts for 0.0032%.

1.3%, zinc accounts for 2.15%, and tin accounts for 0.62%, and as the temperature increases, the solubility will increase rapidly. Although lead, tin, and copper will dissolve in mercury to a certain extent, forming an amalgam alloy, although copper will dissolve in mercury

It does not dissolve much in water, but a large amount of mercury will adhere to the surface. When bronze is immersed in a mercury pool, it will dissolve and adhere to a large amount of mercury!"

"That is to say, although the theory is that this bronze tripod can float on this mercury pool, can also support this hundreds of square meters of mercury pool, and can actually carry a few of us, before it reaches the shore, this bronze vessel will not be corroded by mercury.

The holes will also bond a large amount of mercury to the surface. The total weight of such a large mercury pool will be equivalent to dragging a car, and even if you are Zhao Feiyan, you will sink."

Anyone who has worked in mercury mining, mineral processing, and smelting complexes and is familiar with mercury production and environmental protection knows that when a piece of copper pipe is tried in a mercury waste mercury recovery test, a large amount of mercury will be firmly adhered to it.

Attached to the copper surface, in this case, the material can only be changed to stainless steel pipe.

"Zhao Feiyan, Zhao Feiyan!" Wogua's eyes were shining, he was grinning and drooling. Li Lvyan couldn't help but slap him in the face and drag him back to reality. "You have heard so much about relationships, and you only become serious when you meet a woman?"

This method failed, and Wo Gua pointed at the scripture building again, "Then I'll use this -"

"No, that one is made of stone. The state of an object in a liquid depends on the density of the object and the liquid. If the density of the object is less than the liquid, the object floats in the liquid. If the density of the object is equal to the liquid, the object floats in the liquid.

.If the density of the object is greater than the liquid, the object will sink in the liquid, and the density of stone is 2.8×103kg/m3, so you better not think about it.”

Wogua walked around like a galloping grassland horse on the grassland. People looked for chapters and sentences, but only Zhao Feiyan could give him such motivation.

Obviously, all the materials he saw in front of him could not make Wo Gua understand the reality from Xu Weihang's hypothesis.

Li Green Ant sighed deeply: What if there was a kind of product that could not absorb mercury but could also float on mercury?

It would be nice if it was floating, very large, could accommodate four people, and would not be corroded by mercury. Thinking about it, how can such a good thing be possible? The horse must run and the horse must not eat grass. No wonder Wo Gua

He was excited when he heard about women, but when Li Lvyan told him that Zhao Feiyan was malnourished and had no meat, he was not excited anymore.

The three paths in the sky, on the ground, and under the water are almost the three feasible paths. They can be regarded as the paths that have been exhausted after brainstorming, but none of them work.

Things are back to square one.

At first, Li Lvyan felt that we still have to have dreams, just in case they come true. Now it seems that you still have to work hard when facing your dreams, otherwise you won’t know how painful reality slaps you.

Seeing everyone's gloomy faces, Wo Gua even Li Lvyan, who had always had a bright mind, was unhappy. He came to the side and squinted his eyes and said, "Corporal Dung Beetle, do you think the arithmetic sequence can solve the problem we are facing?"

Li Lvyan couldn't laugh or cry, "I can't."

"What about the geometric sequence?"

"No way."

"Is there any other sequence of numbers that can solve the problem at hand?"

"No number sequence can be applied to it. The arithmetic sequence is not omnipotent. For example, when you are looking for a girlfriend in the future, you'd better not talk about the arithmetic sequence, otherwise the cooked duck will fly away."

Wo Gua turned his head deeply and glanced at Xu Weihang: Could it be that this guy is deceiving me by saying that the arithmetic sequence is a very advanced method?

The scene fell into a stalemate. Li Lvyan suggested that everyone fix it first. Once he heard that Wogua was ready to eat, he immediately stopped talking about numbers and didn't even want to wear pants. But there wasn't much left in his ration. Li Lvyi

The ants haven't eaten much until now, and there are a lot of compressed biscuits left, so they gave some to Wogua. Wogua happily broke them open, and found that there was no water in the kettle. He subconsciously looked around, but saw that it was still.

The mercury pool in Dai Shan'ao's stomach turned out to be Dai Shan'ao's saliva. How many lives and arithmetic sequences were contained in that mouthful of saliva.

The sky quickly darkened, and there were only four people in total, divided into two groups to keep watch. Li Lvyan was afraid that Wo Gua would start a fight with Xu Weihang again, and wanted him to take care of these two while he was thinking about how to cross the bridge. It would also take a lot of time.

He was able to mediate between them, and quickly separated their two vigil shifts, letting Zhuo Ziyan and Xu Weihang go to the same shift, and he was the same as Wo Gua.

After Zhuo Ziyan experienced Li Lvyi's command outside, he seemed to agree with Li Lvyi's arrangements and had no objections to such trivial matters.

Because Li Lvyan couldn't sleep, he took the initiative to take on the first night vigil.

Wo Gua was yawning from exhaustion next to him, and Li Lvyi waved his hand, saying that if he was really sleepy, he could sleep alone. With this, Wo Gua was finally happy and declared a drought.

Li Lvyan walked to the safe boundary. The black line drawn with toner was still there, but he had no clue how to get past it.

The bronze armored guards at night do not look as majestic and majestic as during the day. When the moon shines on them, they look eerie and scary. And because these are bronze giants, their color tends to be more green, so they look green under the moonlight.

, very scary.

Seeing that although they all looked different, their facial expressions were the same, Li Lvyan couldn't help but murmured: These bronze armored guards made by Fang La are placed here to resist tomb robbers, why are they deliberately made into different shapes?

What about the same appearance and expression? What’s the purpose?

Walking low and low, thinking about what happened these days, a photo in his backpack fell silently in front of Li Lvyan. Li Lvyan picked it up and saw that this photo was in the tomb of King Guangling.

I found a group photo of the seven people.

Since Li Green Ant had already torn it apart and looked at it, and knew that the clues were there, Li Green Ant taped it back together again.

Li Lvyan looked at the photo from side to side, a little bored, and suddenly a spark flashed in his mind.

wrong!

wrong!

There is a misunderstanding in my thinking!

I was cut to pieces because the bride rolled across the bridge in front of me, so I intuitively knew that there was no way to cross this bridge, but before me, at least a few people in the photo had climbed over it quickly.

Black Glasses also said that before our group, it was indeed some of the people in the photo who found the clues here first. He found a total of two photos, one was the one in his hand, and the other was the one in the photo.

From the photo of a few people standing in front of the locust tree in the big house, judging from the condition, their previous group photo clothes should have been in autumn, that is, the group of people who went to the tomb of King Guangling first took the photo in autumn, and then

The photo taken under the locust tree was obviously in summer, which means that there was at least a year between them, and for some special reason, they took the photo again after a year, so they re-written it after the photo was taken.

clue.

If the clues in the previous photos are speculations, the following ones are confirmations, that is to say, they must have come here in person and successfully walked out of here!

I didn't see any bones on the bridge just now. The bridge was very clean. Because of the density of the human body's bones, even if the body was really poisoned by mercury and left lying on the mercury pool, the body would not sink. That's why the person who took the photo later said

, they must have returned alive!!

This shows that there must be a way, a way to successfully cross this bridge, but it has been ignored by myself.

What is it?

Li Lvyan sighed, and when he was about to turn back and take another look at the bridge, he suddenly felt a chill on his neck. He looked sideways, but saw a man with a face.

The painted bronze man with a broad nose and no pupils lay beside his ear and said in a daze, "I've been trapped here for too long."

Li Lvyan's hair suddenly stood up: How is it possible? How could these bronze figures move?! How could they move?

The bronze man had no pupils, but he had the whites of his eyes. However, he saw that the whites of the bronze man's eyes suddenly rolled violently in his eye sockets. He lowered his head slightly and looked at Li Lvyan, "It's been a really long time."

The painting on his face looked weird and expressionless at this moment, but it inexplicably contained a hint of gloom and unreasonable terror. Li Lvyan felt that his heart was going to jump into his throat, but the whites of the bronze man's eyes were...

There was a sudden pause, and his wide mouth suddenly circled, as if he said "kill". Then, the bronze man raised the long knife in his hand and struck Li Lvyan viciously on the head.

Li Lvyan felt his heart tremble, his whole body split in two, and he sat up reflexively with a whimper.

There are few stars in the moon, and the clear moon sky remains the same.

Li Lvyan rubbed his eyes, Wo Gua's snoring continued, Xu Weihang and Zhuo Ziyan seemed to have fallen asleep, and there was silence all around. Those bronze figures were still standing there, as if there was nothing from the beginning to the end.

action.

Li Lvyan patted his chest: It turned out that he accidentally fell asleep. Fortunately, it was just a dream.

I shined my wolf-eye flashlight around to see if anything unusual happened around me while I was sleeping. When I shined the light on those bronze figures, suddenly the paintings on the faces of those bronze figures seemed to change their expressions, becoming extremely sinister.

The pupils and the whites of the eyes suddenly turned together, and they kept shaking "gurgling", which was very scary.

Li Lvyan's scalp felt numb. He was afraid that he was still dreaming, so he pinched himself hard and found that it hurt very much: it was not a dream!

Shake Wo Gua awake, wake up everyone, pick up the pistol and walk towards there step by step.

Zhuo Ziyan moved upon hearing the sound, and stood side by side with Li Luyi, with the mumbling Wogua and the sleepy Xu Weihang behind. Li Luyi briefly explained what he had just seen, and Wogua yawned.

"I'm telling you, Corporal Dung Beetle, your nerves are too tense during the day. It's normal to have nightmares. Maybe you're just blind. The perfectly fine bronze man is a dead thing, not a living thing. What are you afraid of?"

But when he walked outside the safe boundary, Wo Gua's yawning hand suddenly stopped in mid-air, and he saw the whites of the eyes of countless bronze figures turning fiercely in their eye sockets, as if they were controlled by machines without emotions, because the pupils were missing.

, seemed unreasonably terrifying, Xu Weihang couldn't help but screamed in fright. At this moment, the original sound of "gulu gulu" rolling the whites of his eyes suddenly disappeared, and the pupils of the bronze man, which he had never seen before, actually appeared out of thin air!

"Jie Jie——"

The shape of the bronze man did not change, but his heads were all facing this way. It would be false to say that he was not afraid of such a mysterious scene. It was the first time Li Lvyan encountered it, and he almost couldn't even hold the gun.

Zhuo Ziyan fired several rounds at the bronze men, but the bullet hit the bronze man's head. He only heard the sound of gold and jade colliding, and then the bullet bounced away: it was not a monster.

"Run!"

Before anything happened, Xu Weihang was the first to run away. After the pupils of the bronze figures were revealed, the expressions on their faces began to change, turning into either sinister or vicious smiles.

"Jie Jie——"

"Jie Jie——"

The laughter of dozens of bronze figures was like howling wolves on the plain, breaking the silence of the night. Zhuo Ziyan had a strong psychological quality, but he still couldn't help but retreat when he encountered such an extraordinary thing.

step.

In fact, the action team he belongs to deals with a series of unnatural special situations. However, most of the unnatural special situations are just spread by rumors. After investigation, it is found that this is not the case. The few times they encounter it, they can also be dealt with with absolute weapons.

Crush the past, but now this situation——

The bronze figures kept laughing and pointed their heads in this direction. Li Lvyan observed it for a while and suddenly shouted, "Don't panic, everyone, these things can't move!"

Um?

Xu Weihang, who was running around, suddenly stopped when he heard these words. When he saw those things, he could only turn his head and laugh secretly, but other than that, there was no movement at all, which was very strange.

Li Lvyan used his wolf-eye flashlight to shine a light on it, and finally discovered abnormalities in the left and right legs of each bronze man.

He found that the left and right legs of these bronze figures seemed to be connected by two solid steel pipes directly embedded in the bridge and inserted into the body, making these bronze figures unable to move. The necks of these bronze figures seemed to be movable. This

This resulted in a situation where their necks could move but the rest of the body could not.

Looking at the expressions of the bronze men, Li Lvyan felt a chill in his heart. He thought of the doubts he had when he saw these bronze men for the first time, and now he had a bold idea.

With a somewhat complicated look on his face, Li Lvyan's voice seemed particularly distant and silent in the night.

"These bronze figures with single expressions should be -" Dun "It should be that a hole was cut out of the scalp of a living person, and then mercury was poured into the hole. When they are still breathing, they can be put down and filled with mercury.

A Gu insect that has survived for thousands of years, mercury completely stabilized its body shape. When the person was still alive, he directly held down his hands and feet and inserted them into a solid steel column to prevent him from breaking free. Finally, he was successfully shaped and then painted with imitation bronze paint on the surface.

That’s it—that’s the origin of these bronze armored guards.”
