Last time, I talked about Shen Yifan and Professor Wang; Liu Yao and the others came to an underground river, set up camp by the river to rest, Shen Yifan and Liu Yao chatted about their views on the ancient tomb in front of them, Shen Yifan also talked about his views on an ancient tomb, he was very sure that they must have gone to the right place.

As mentioned above, Shen Yifan had gone to see the feng shui dragon veins of Heiniu Mountain before, and according to Shen Yifan's knowledge of feng shui, there are clouds in the comparison: the clouds can be hidden for a hundred miles, and the three-story treasure hall is trapped in it. There are mountains, rivers and lakes inside, and mountains of gold, silver and jade are piled up. The nine sections are rugged and different, and the summit is known. Ask me how to get to this temple, a river of Styx leads to three places. From Black Bull Mountain to here, many things have been written in this poem.

Heiniu Mountain seems to be plain on the surface, but in fact, there is a mystery in the belly of the mountain, which just fulfills the fact that there are mountains, rivers and lakes inside. In addition, the Zheng family in Guwuzhen has relied on this kind of ancient tomb for several lifetimes, which corresponds to the mountains of gold, silver and jade. The zigzag tomb is weird, and the spiral staircase corresponds to the nine sections, which are rugged and different. An underground river in front of you corresponds to a river Styx leading to Sanda. All kinds of signs made Shen Yifan sure that this underground river would definitely lead to the last ancient tomb.

Shen Yifan said his thoughts, he said: "The way back is definitely not able to go again, I suggest that we follow this underground river and see if we can find a way out." ”

Professor Wang and his students are both engaged in theoretical knowledge, so if they encountered this kind of thing, they had not paid attention to it until now, and when they heard what Shen Yifan said, they all nodded in agreement.

Shen Yifan said: "Then let's spend the night here today, and find a way to find something to go into the water tomorrow." ”

The big man at night, Wang Yunfei and Shen Yifan The three men took turns to keep vigil, Wang Yunfei and the big man were intellectuals after all, this toss was already tired, Shen Yifan didn't wake them up, he looked at the river beach and was thinking about things, and he didn't know when he fell asleep groggily, and when he woke up, the alarm clock of the watch woke him up, and when he opened his eyes, he saw that he was covered with a blanket, and the bonfire next to him had been added with firewood, and it was crackling and burning even more.

He rubbed his eyes and saw Liu Yao sitting by the fire, holding his head tilted to look at Shen Yifan, Shen Yifan sat up smartly and asked, "Didn't anything happen?" ”

Liu Yao shook her head and said, "It's okay!" ”

At this time, Professor Wang and his students also woke up, and Shen Yifan said, "I'll go to the front and have a look." You guys are here to prepare. ”

Liu Yao also went to the front with Shen Yifan to explore the way, and after not walking much, he found a dilapidated ancient dock. This pier is very simple, it is a wooden stake directly inserted into the river, and there are several dilapidated canoes on it, this canoe is useless at first glance, but it can still float on the water after being soaked in the water for thousands of years.

Shen Yifan said: "There is a forest further ahead, and I guess these canoes are all made of local materials in that forest. ”

Liu Yao listened with some disbelief and said, "Without any photosynthesis, how do these trees grow?" ”

Shen Yifan said: "It may be a special variety, just like gloomy wood." ”

The two of them were afraid that Professor Wang would have any troubles, so they didn't go too far, and walked a little further towards the pier before turning back.

Back at the camp, Shen Yifan said: "The road is full of broken pottery and broken tiles, there should be a forest in front, where can we find materials to go into the water." ”

Professor Wang took advantage of the gap between Shen Yifan and others to explore the road and the students looked at the broken pottery and tiles on the ground, and determined that the things here should be defective, and they were thrown here.

After everyone took care of everything, they began to set off along the river beach, and there was nothing to say all the way, and a team of people came to the edge of the forest that Shen Yifan said, everyone looked up at the dense forest, and they were all speechless, and the trees in the forest looked like stones, from the trunk to the branches to the leaves were as black as coal.

Professor Wang said in surprise: "I have never heard of such a scale of carbonized forests!" ”

Shen Yifan was also surprised and said: "This forest should have been there when the heavens and the earth first opened, otherwise it wouldn't have grown so dense and huge, could it be that the earth's orogeny or other reasons will make this forest become what it is now?" ”

In fact, this phenomenon is not a good thing for them, because the trees are all carbonized into fossils and cannot be used, and now the only way is to cross the forest in front of him, one thing Shen Yifan can clearly know that the end of this forest must be a dead end, because the scale of the cave is not very large, and the underground river stretches into the stream, and it is across this cave.

Shen Yifan insisted on going into the water and taking the waterway, but it was also a headache that there were no very suitable materials in front of him to make a raft, and finally Shen Yifan decided that the disciple would enter the petrified forest alone to see if he could find the materials to make the raft.

Because everyone didn't expect the current situation at the beginning, the equipment they wore was not very complete, and finally decided that the big man and Shen Yifan would enter the woods, and the others would still wait for news on the edge of the woods, with the bonfire as the fixed target.

Shen Yifan handed the ground to the big man for self-defense, holding a sky-covering umbrella in his hand, and headed towards the petrified forest with a torch

, probably just a cigarette, the two of them saw by the light of the torch that there seemed to be a dilapidated house in front, in the middle of the woods, the dilapidated house was full of vines, and the two came to the dilapidated house and walked around twice to see the details.

Shen Yifan said: "We are really lucky. ”

The big man couldn't understand what Shen Yifan meant, so Shen Yifan explained to him.

The dilapidated house should have been built by people who built tombs here thousands of years ago, the reason is very simple, this should be a logging field at that time, Shen Yifan has heard of a rare tree species called 'dark fragrant wood' diameter in the dense jungles of Southeast Asia will also be found, this kind of tree is very precious, it is said to have the effect of resurrecting the dead, and the current market price is calculated in grams. Shen Yifan had seen the transaction of this kind of wood, and a dark fragrant wood the size of a toothpick was actually priced at 150,000 yuan.

The woods in front of me were such trees, and the guards of the lumberyard had built a hut from local materials, and the vines that wrapped around the ruined house were not actually vines, but grew out of the 'dark incense wood'.

It may be an exaggeration to say that dark fragrant wood can come back to life, but the effect of dead wood in spring is indeed there, it is said that there is a fragrance in the inner essence of this wood, and the wood itself has a effect of preventing decay, even if a period of dark fragrant wood can grow new shoots without any photosynthesis and nutrient water for a long time, and become a vine-like plant, and the biggest characteristic of this wood is that it is strong.

Shen Yifan said: "This broken house is wrapped in these vines so it is not petrified, so the wood of those broken houses is still okay." ”

The big man said, "I'll call the professors." ”

Everyone came to this dilapidated house, began to clean up the vines and dilapidated wooden houses, busy for more than an hour to clean up the vines around the dilapidated house, although the wood is strong but also long, when the vines are cleared, the dilapidated house itself fell, and everyone spent more than an hour to tie the vines and the wood of the dilapidated house into a raft.

The dark incense wood itself is very strong, and although the vines that grow from the dark incense wood can be cut with a knife, they are very tough and can be used to tie the raft, and by the time the raft is tied, it is already afternoon. After everyone had eaten something, they carried the raft into the water.

The water of the underground river is very fast, and as soon as the raft enters the water, after jumping on the raft, the raft moves directly along the water without paddling, and the speed is very fast, and it has already floated through the forest in a blink of an eye.

A torch was inserted in the front and back of the raft, but everyone had not had time to look at the situation on both sides, the raft had already passed the cave, and the speed of the raft after the cave was even faster, and everyone felt that they were drifting on the raft at the limit, but fortunately, the water level of the underground river was relatively high, and there was no obstruction on the water surface, so the raft was unimpeded.

There is nothing special in this cave, and the speed of the raft is also fast, and everyone's eyes have no time to take care of it, when Shen Yifan saw a gap in front of him, he shouted: "Hold it steady." As soon as the words came out, I felt the raft fall straight down, lapping on the water, and the current began to slow down.

You can obviously feel that the water level of the underground river in this cave is much shallower, but the whole cave does not have any land, it is a water hole, everyone looks back and sees that there is a drop of two meters high, and the water flow is formed into a waterfall and goes down, maybe the river here is relatively wide, so the water flow will slow down.

Under the firelight, everyone looked around, and found that this cave is a little different from the original cave, this cave not only has no land, but the two sides are extremely smooth, looking up at the top of the cave is a rounded arch, obviously there are traces of artificial construction, it does not look like a cave, but more like a very spacious tunnel.

The tunnel was pitch black, except for the two unlit torches on the raft, there was no light source, everyone slowly rowed the raft with the tools in their hands, and went to the depths, after the tea effort, the raft had reached the end of the tunnel, what I didn't expect was that this water tunnel was actually a dead end, and everyone couldn't help but be a little frustrated.

Shen Yifan said: "I'll go into the water and take a look." ”

Saying that he had jumped into the water, the water of the underground river was cold and biting, Shen Yifan was frozen as soon as he went, gritted his teeth and dived into the bottom of the water, because it was pitch black, Shen Yifan could only fold a few glow sticks, and saw a wall in front of him, and then a door hole could be seen, which was full of water, and it seemed to be a tunnel leading to the inside.

Shen Yifan surfaced, took a long breath and climbed onto the raft again and said, "There is good news and bad news, you have to listen to that first?" ”

Liu Yao said: "Let's talk about the good news first. ”

Shen Yifan wiped his face and said, "The good news is that there is a tunnel down there, which should lead to other places. The bad news is that we're only going to have to dive. ”

Everyone was dumbfounded when they heard this, and the big man said, "We don't know this kind of thing!" ”

Shen Yifan said: "I'll tie the rope and explore the way first, and when I come back, I'll teach you how to do it one by one." ”

Liu Yao was a little uneasy when she heard this, and asked, "Hey! Can you do it alone? ”

Shen Yifan nodded and said, "It should be no problem." ”

Liu Yao helped Shen Yifan tie the rope around his waist, this kind of military paratrooper rope looks thin but very strong

, Shen Yifan explained that Liu Yao would send the glow sticks to everyone, and the darkness under the water must rely on the light sticks.

Saying that Shen Yifan entered the water again, and walked all the way along the tunnel, the length of the tunnel is actually not very long, about ten meters away, there are mottled murals on both sides, but after soaking in the water for a long time, he can't see what is clear, through the tunnel Shen Yifan floated directly, and poked his head out of the water in less than a minute, the brightness of the glow stick can be seen clearly here, he has arrived in a large artificially built palace, and the place where he surfaced is actually a lotus pool.

After Shen Yifan fixed the rope, he dived into the water again along the way back, and when he appeared on the side of the raft again, everyone was relieved.

Shen Yifan told what he saw, everyone was excited, as if they had been injected with a stimulant, and they all entered the water along the rope one by one, Shen Yifan repeatedly explained that he must swim forward with the rope and pin the glow stick to his clothes.

Just when everyone had already entered the water, Shen Yifan clearly heard a snap behind him, as if something had fallen from the top and fell into the water, Shen Yifan followed the firelight on the raft and saw a hydrofoil appear on the calm water, and then he heard more and more of this sound, and countless hydrofoils quickly came towards them.

Shen Yifan's scalp was numb and shouted, "Hurry up!" There is danger. ”

As soon as he finished speaking, he felt a tingling pain in his feet, and when he grabbed it and raised his hand, it was a thing that was only the size of a thumb like a meat rat, this kind of thing had no eyes, only gills and mouth, and two rows of sharp teeth in its mouth, and when it was grabbed by Shen Yifan, the mouth was still biting wildly.

Shen Yifan didn't know what this thing was, judging from experience alone, this thing was probably very dangerous, and when he saw that Wang Yunfei also dived into the water in the end, he also hurriedly plunged into the water, and then the glow stick saw countless unknown things like meat rats swimming towards them in the water.

Seeing that the big man's whole body was full of this kind of thing, the whole person had been bitten like a string of blood gourds, and the whole person was spitting blisters in the water, dancing and scratching.

Shen Yifan hurriedly swam over, helped the big man grab a little of the things on his body, and pulled the big man towards the depths of the tunnel.

But the speed of this kind of thing in the water is very fast, seeing that countless unknown things like meat rats are about to pounce over, Liu Yao hurriedly opened a bottle of liquid in the water, this thing quickly spread in the water into a cloud of earthy yellow liquid, and sure enough, those meat rat-like little things seemed to lose their direction in the earthy yellow liquid, and they were circling around in the liquid.

Everyone hurriedly took advantage of this gap and pulled the rope forward, and after a while, everyone surfaced from the lotus pond, Shen Yifan and the big man were the last to come up, Shen Yifan still had a few meat rat-like things left on his body, and quickly grabbed them and threw them on the ground.

The big man was not so good, his whole body was covered in blood, as if he had just been fished out of a tank full of blood, and the whole person had been bitten and dying.

Lin Yu was already crying bitterly when he saw this situation on the side, Wang Yunfei and Professor Wang were both squatting next to the big man to watch his situation, Shen Yifan looked at the big man and knew that he couldn't be saved, and he beat his chest hard, and he was also very annoyed.

Liu Yao pulled Professor Wang and said, "Professor! Don't be sad. Li Meng will be fine. ”

Li Meng is the name of the big man, he is also a student of Professor Wang's more proud, now there is no good place in the body, watching Li Meng slowly swallow, everyone can't stop their grief, as if venting everything, they cry one by one, except for Shen Yifan.

Shen Yifan was disturbed by this kind of crying on Li Meng's pulse, and suddenly shouted: "Don't cry." He is still saved. ”

When this sentence was shouted, everyone's crying immediately stopped abruptly, and they saw that Shen Yifan would use the only bandage to help him bandage a few more serious injuries and said, "Fortunately, there are no fatal injuries." He had just bled too much and was in shock. As long as he can be taken out in time, his life will not be in danger. ”

After hearing this, Professor Wang breathed a sigh of relief and said, "Okay! Good! Good! ”

Shen Yifan looked at Wang Yunfei and said, "From now on, you are responsible for carrying him." ”

The big man Li Meng is fine, Wang Yunfei is a hundred willing, and he is full of promises. Shen Yifan asked Lin Yu to take care of the big man on the side, while he lit a simple torch and looked at the surrounding environment.

Shen Yifan looked around and asked, "Professor Wang." Is this the style of the tombs of the Xia Dynasty? ”

Professor Wang looked at the palace in front of him and said, "This is not a tomb. It should be a relatively large-scale sacrificial place, and it should be called a temple during the Xia Dynasty. ”

"Temple?" Shen Yifan was also a little surprised, and said to himself: "A temple built underground? ”

Is the palace in front of them a tomb or a temple? Will these people be able to get out of here? What exactly is inside this underground building of the Xia Dynasty? How could the wild southern tribes of the Xia Dynasty have such technology to build a building of this scale underground?
