Shen Jinsan saw that the road ahead was broken, so he had to go back the same way, Guo Fatzi lifted him out of the cave, and the four of them sat there to discuss, and finally decided to climb down this strange big tree to have a look.

Guo Fatzi connected all the ropes end to end and tied them together, one end was still tied to the stone platform, and the other end made a horse ring that could be tightened by pulling it, and Shen Jinsan took it to climb down first.

The wind blew Shen Jinsan's eyes narrow, in order to better exert his strength, he had to leak half of the soles of his feet to the edge of the mouth, and when he threw the rope several times, he almost fell down, and the soil on the edge of the mouth also collapsed a large piece, it seems that this place is not very strong, after trying many times, the horse ring finally hung firmly on the tree, and Shen Jinsan's hands couldn't stop trembling.

After receiving the instructions, the others also climbed down one after another, sat on the ground in a row and pulled the rope tight, while Shen Jinsan hooked the rope with his limbs and climbed towards the big tree.

The three people who hold the rope feel very difficult, just as once a kite eats the wind and takes advantage of the momentum, the force used by both hands holding the string will inevitably increase exponentially.

Shen Jinsan was so dizzy that he couldn't find the north, he tightly wrapped the rope and didn't dare to move rashly, feeling that as long as his limbs moved slightly, he would get out of his hands.

"Shen Jinsan! Hurry up! If you really can't do it, go back! Guo Fatzi shouted there: "Pull tight! Otherwise, he'll be shaken down! ”

Shen Jinsan was already in a dilemma, he knew that if he was not happy, Guo Fatzi and they would not be able to hold on, at this moment the rope was pulled tighter, and the swing became a little smaller, and Shen Jinsan finally moved to the big tree with all his might.

Seeing Shen Jinsan land safely, Guo Fatzi and the others were relieved, immediately loosened the rope and sat on the ground panting, Shen Jinsan took off the excess part of his rope and put it away in case other places needed to use it, and after re-tightening the tie firmly, the other three climbed over one after another with relative ease.

At this moment, these four people couldn't believe their eyes at all, originally they thought that this was a giant tree that had been deliberately cut off from excess branches, so that it became such a regular appearance, but now it seems that this so-called big tree is not a tree at all.

Numerous small sticks of various thicknesses and rough surfaces were inserted into a huge rod that looked like a tree trunk at almost equal intervals, with only one inserted into each section at a fixed distance, and were arranged in order to form a spiral-shaped staircase.

Shen Jinsan slammed the submersible knife on a stick above his head, and immediately there was a crisp and pleasant sound, and then scraped it with the knife, which could scrape off some black powder, revealing the dark green essence inside.

The material of this thing is very hard, and it has a certain toughness, it is close to the texture of metal, but it does not have the luster of metal, just like a strengthened version of rosewood, Shen Jinsan remembered what Wu Zhengyi said in Jinling, this material is not in the five elements, so it has not been absorbed by the five elements of fire, isn't this thing from the earth?

"What the hell! Why is it in such a place! Guo Fatzi shouted and interrupted Shen Jinsan's thoughts.

Shen Jinsan: "How do I think, this seems to be a huge ladder!" ”

Guo Fatzi: "This thing can also be called a ladder?" ”

Shen Jinsan: "If it is made into the kind of ladder we usually use, if you want to make it firm for such a long distance, you must use two very thick pillars as support, but if it is made like this, one pillar is enough, it can save almost half of the material, and it will be much easier to process." ”

"I feel that way too, ah Jen, what do you think?" Wu Xin deliberately asked Ah Zhen, because Wu Xin felt that Ah Zhen might know some secrets here, and when she destroyed the bark in the coffin, Wu Xin was still haunted.

"I don't know! Look at the bones of the dead! Ah Zhen steered the conversation away.

Indeed, this is also a problem they have to face, the remains around them are incomplete, and there are obvious traces of being gnawed by wild beasts on the bones, Shen Jinsan faintly feels that it is not good, will there be other creatures in this bottomless pit, so he hurriedly reminded: "Look, there are many tooth marks on the bones, there may be other things that will bite people here, let's try not to make too much movement!" ”

Guo Fatzi: "Don't you say, I really didn't expect that this ladder is not easy to climb, in case an animal comes up and wants to bite someone, if it moves slowly enough, it's okay, otherwise, we will be miserable!" ”

Wu Xin: "Could it be that it was followed up from outside?" ”

Shen Jinsan: "No, the army was transferred back then, and the entire cat's eye hole was closed, and there are no particularly ferocious animal activities in this area." ”

Jane: "Don't forget the zombies up there!" ”

Guo Fatzi: "You mean, there are zombies down here?" ”

Wu Xin: "Trouble! It's really not easy to make moves on this big stick! ”

Shen Jinsan: "Let's climb a section first, after so many years, the biting thing may not still be there, maybe it has been wiped out by the army, let's not scare ourselves first!" ”

Guo Fatzi: "That's right, it's not a matter of having a tea party here!" ”

Following Shen Jinsan's advice, everyone began to climb down, and on the way, several dried corpses tied there passed by them, and after a little inspection, they could also find that these remains were also mutilated, and they were covered with tooth marks.

Ten minutes later, only the four of them were left panting on the big stick, and nothing else was to be seen, and they didn't know when they would reach the end.

I don't know how long it has been, the world has long become a void of darkness, because they are afraid of wading, so they put the mobile phones that can be used to keep time in the car, at this time they only have some tools and compressed food to satisfy hunger and the two Motorola walkie-talkies.

Guo Fatzi's stomach was hungry, so he estimated that he had been crawling for at least four or five hours: "I said stop first!" ”

Shen Jinsan: "What are you doing?" ”

Guo Fatzi: "Have you noticed that this ladder is oblique?" ”

Wu Xin: "How do you see that?" ”

Shen Jinsan: "Yes, it's indeed oblique!" ”

Guo Fatzi: "Look, we're getting closer and closer to the wall over there. ”

Jane: "What does that mean?" ”

Guo Fatzi: "I still don't understand!" Either this big pit is crooked, or this ladder is slanted, in short, it means that we are about to go to the end! ”

Jane: "Then don't talk nonsense, hurry up, it's better to find a place to rest!" ”

As expected, after an hour, they had climbed to the bottom, but this bottom was not the end of the ladder, but a large pool of crystal clear water, and all the walls around it a little higher than the water had been hollowed out, forming a ring of space that should be used for rest.

After illuminating the water, they could see the ladder going deep into it, but there was still no end in sight, and the water was so deep that it was estimated that the distance they had descended was only a fraction of the length of the pit.

Everyone thought it was strange, it stands to reason that there should be algae and burrowing animals breeding in the groundwater, especially this large area, which can be counted as an underground lake, but the water here is a little clear, the water surface is as quiet as a mirror, and there is no life in the water, and no living creatures can be seen, even a small tuft of water moss.

"This water is so weird!" Wu Xin picked up a little and put it in front of his nose to smell: "There is no smell, it is just ordinary water, but I feel that this water is very heavy." ”

Guo Fatzi: "I don't even have a fish!" If it weren't for the reflection, I wouldn't have seen this puddle of water! ”

Shen Jinsan also scooped it up and looked at it, after drying his hands on his pants, he took out the cigarette case from his pocket, he took out a cigarette, crumpled it all and sprinkled it into the water, everyone saw an incredible scene, the tobacco, the filter and the soft cigarette paper all sank into the water, and kept sinking until they were out of sight.

Guo Fatzi: "Fuck! What the hell. ”

Shen Jinsan clapped his hands and said, "This is heavy water, and the concentration is very high, we have to be careful!" If you fall, you won't be able to get up! ”

Guo Fatzi: "Then how do we get to the other side?" What is Heavy Water? Is it poisonous? ”

Wu Xin: "You can't ask one by one!" ”

Shen Jinsan: "Heavy water is also a kind of water, but there are a few more isotopes than ordinary water, and there will be a very small amount of heavy water in the water we usually drink, you don't understand this, in short, the toxicity is very weak, as long as you don't eat it, it's fine, and you can drink a few sips when you're thirsty." ”

Guo Fatzi: "Damn! How do you know I don't understand! ”

"I don't think you have any culture!" Wu Xin looked like he was smiling: "Where does this water come from?" ”

Shen Jinsan: "In nature, there is very little heavy water, and it is very troublesome to refine, there are so many here, it should be naturally formed, this kind of heavy water with a high concentration is thousands of times more expensive than gold, such a large amount, it is estimated that it can buy a country." ”

Guo Fatzi: "Huh? When we go out, we can pack as much as we can! ”

Wu Xin: "Who are you going to sell to?" ”

"Weak water!" Ah, Jane whispered.

"Weak water?" This was just heard by Shen Jinsan: "What do you mean? ”

Ah Zhen: "I just heard that weak water only exists in the territory of God, protecting God from being violated, even God cannot swim in it, and then God came to the world to create man and also brought weak water, after God left, weak water remained in the world." ”

Shen Jinsan: "The Classic of Mountains and Seas" said that there is water in the north of Kunlun, and its strength cannot defeat mustard, so it is called weak water, Kunlun said in the Book of Mountains and Seas, which is where the gods live, the ancients believed that weak water is the most sinister water, and anything will sink and cannot float, and the water here may indeed be weak water, so we can't get to the other side at all! ”

"Oh yes! Isn't it a toss for nothing! Maybe the "Yin Yang Sutra" is in there! Guo Fatzi pounded a stick above his head.

"Smack~~~~~~

The rod was knocked off and fell into the water, and it miraculously floated on the surface of the water, and it was really surprising that the rod like steel and iron could float on weak water, which completely violated the common sense of physics.

Shen Jinsan was overjoyed: "There is a way!" It seems that neither of these things is mortal, so let's get a few of them and tie them together as floating boards. ”

Guo Fatzi: "It's really brought by the gods?" ”

Wu Xin gently patted the back of Guo Fatzi's head: "He's just making an analogy!" We have to go down to the water and get it, and we can't move the top of our heads, or we won't be able to go back. ”

Shen Jinsan: "This thing is too short, you have to get a lot, in case you can't support one person, it's too late to save it, I'll dive down first to get it, and the fat man will relay!" ”
