After watching this video, Li Yuanhong knew that his task of stepping into the last transmission gate could not be shirked. Otherwise, once the space-time giant opened the door of space-time, with the existing technology of the earth, it would be impossible to resist the attack of the giant beasts.

"Life, it's all life." Li Yuanhong sighed to himself.

After the end of the second video, Li Yuanhong pressed several buttons, which recorded some researches on space-time giants. After a brief look, Li Yuanhong skipped them. Because when Li Yuanhong was bored, he pressed a button, and the playing screen stopped, just like the pause button. Then Li Yuanhong tried several other buttons to find out At the fast forward and backward button, the stone table is actually a transmitter, and the skull is like a storage device, storing the records of prehistoric civilization.

When Li Yuanhong was about to take out the skull, he suddenly turned to the record of the construction of the pyramid.

It was a dark river, which prehistoric civilization used to transport stones and other materials, and finally the whole pyramid was built on it. Moreover, the energy of the pyramid is driven by the current of the underground river. As long as the underground river keeps flowing, the internal energy of the pyramid will not be lost.

This explains why after tens of thousands of years, the various mechanisms, magic and other energy devices in the pyramid will still work, that is to say, the dark river is still running.

Li Yuanhong was interested in this discovery. Before that, he only considered how to leave here. With this underground river, he could go back to the sea with the help of the underground river. When he got to the sea, he could send a signal to Xu Ying, and soon he could return to the fleet.

But how do you get to the river? You should know that the whole pyramid is pressed on the dark river. There is no ready-made channel. You have to dig it by hand. If you are tired, you may not be able to dig it successfully. What's more, once you dig it yourself, you may disturb those alien demons.

just as like as two peas in Li Yuanhong's mind, the video at the end of the video gave a map of Pyramid, which is almost identical to the map before Li Yuanhong. If Li Yuanhong had no real eyes, the others would think that the two maps were exactly the same.

However, Li Yuanhong was very keen to find that in the new map, there was a thin line near the stone table connecting with the underground river. However, the thin line was too small to be ignored.

Li Yuanhong quickly took a picture of the whole map, then called his mobile phone and compared it with the map on the top of the pyramid before. As expected, there was an extra thin line on this new map.

With a new discovery, Li Yuanhong began to search the room to see what the thin line represented.

Finally, not far from the stone table, Li Yuanhong found a different stone brick. There are two small holes on the stone brick, which are very similar to the holes used to pry on the well cover. So Li Yuanhong took out two iron bars, tried to reach into the two holes, and then pried up. The brick was pried up, revealing a round hole below.

This hole is very similar to the sewer entrance shaft before the end of the world. The round shaft can only pass through one person. If two people go down at the same time, they will definitely be stuck at the mouth of the well.

Even if not two people, such as Lu fat man's fat body, in front of this wellhead, I'm afraid they will be stuck.

Of course, Li Yuanhong doesn't have to worry about this. He can easily drill into the well head. Li Yuanhong restored the floor tile when he entered the well head. This floor tile is not a secret door. There is no way to restore it automatically. Li Yuanhong can only do it himself. Of course, in addition to the well cover, Li Yuanhong has replaced the crystal skull in his watch. There are many places for research on this crystal. How can it be left here to waste.

As soon as the floor tiles are covered, the whole shaft becomes airtight, and a depressing tide suddenly fills the whole space.

"Why are you so connected with this kind of black hole today?" Li Yuanhong sighed, turned on his headlight and began to climb down the ladder tens of thousands of years ago.

"I don't know if the ladder is still strong!" When Li Yuanhong stepped on a ladder, he felt that the ladder was a little soft. Apparently, it had been corroded for tens of thousands of years.

Just as Li Yuanhong had just thought about this problem, he suddenly felt empty, and the ladder below was really eroded. His body suddenly sank when he stepped on it empty.

This sinking increased the gravity of Li Yuanhong's whole body. There were already some soft ladders that could no longer bear Li Yuanhong's weight. The horizontal ladder grasped by Li Yuanhong's hands and the ladder stepped on by his other foot broke at the same time, and Li Yuanhong's whole body lost balance and fell down rapidly.

Li Yuanhong suffered a lot. The shaft was not big, and Li Yuanhong's fall was still in the half lying position. Inevitably, his body was in contact with the well wall, and it was that kind of violent friction contact, so that Li Yuanhong's body was bruised in many places.

Fortunately, Li Yuanhong's physical evolution is strong enough, and all the collisions are not enough to cause fatal injuries to Li Yuanhong, but these collisions still make Li Yuanhong suffer a lot.

It's not a matter of being blue and blue, and slowing down at a stall. But the problem is that Xiang Li Yuanhong has dropped nearly 100 meters in a row. The shaft has not yet reached its end. You should know, this is an artificial shaft, not a natural cave, and it is almost surrounded by rocks and no soil. How much manpower and material resources are needed to dig such a shaft.In fact, Li Yuanhong was wrong. The stones around the shaft can be regarded as the base of the pyramid. In those days, the pyramid used an underground river to transport stones and then built pyramids on the underground river.

Li Yuanhong was already a little dizzy when he heard the sound of running water, and then the strong water vapor came to his face.

Li Yuanhong knew that he was going to the end, so he quickly took out a flare from the space and threw it down. With the flare burning, Li Yuanhong soon saw the scene below.

There is a small platform below, which should be used for the people above. Next to the platform is a big river that keeps running. Because the well head is very small, we can't see how big the river is.

Li Yuanhong knew that he was going to the end, so he quickly applied his blink and removed his inertia. If he fell directly on the platform, Li Yuanhong would have become meat mud.

When Li Yuanhong fell on the platform, he felt pain all over his body. He even picked up a big bag in the back of his head. All of these were bumped on the wall when he fell off the ladder just now.

After recovering for a while, he drank a bottle of red liquid medicine. Li Yuanhong felt that the pain was not so heavy, and began to look around.

The platform is also built of boulders. Due to being washed away by the current for many years, the platform has become extremely smooth without edges and corners. Fortunately, the boulder is big enough, so the whole platform has lost some edges and corners and has not completely disappeared.

At one end of the platform, there was a stone chamber, which surprised Li Yuanhong. The stone house was not marked on the pyramid map.

So Li Yuanhong curiously went to the stone house door and looked at it carefully. He found that it was just a common stone door. Then he reached out to push the stone door. With a "squeak", the stone door was slowly pushed open, revealing a large stone chamber.

Li Yuanhong walked into the stone chamber and found that the stone chamber was full of all kinds of machines and arrays. These arrays and machines were connected with the flowing water below, and they were running in an orderly manner. Those arrays also gave out a faint magic light.

Li Yuanhong finally knows what this stone house is for. This is the power core of the whole pyramid. The power of the river water is transformed into the operating energy of the pyramid, and then transported to the pyramid. The shaft should be a passage for maintenance personnel, but the passage is too long. It is estimated that no one can climb it before the end of the world Channels.

Li Yuanhong knows the purpose of the stone chamber, but he will not destroy the devices here. Once those demons find something abnormal, it will affect his plan.

Li Yuanhong withdrew from the stone chamber, and then walked to the edge of the dark river. Looking at the turbulent River, Li Yuanhong hesitated for a moment, then quickly took out a set of diving equipment from the space, put it on, and jumped into the river.

The underground river water is no better than that of the outside river. After entering the water, Li Yuanhong immediately felt chilly. If the diving equipment was not equipped with magic array to keep warm, it was estimated that Li Yuanhong would lose the ability to swim due to muscle stiffness once he entered the water.

The river is very fast. Li Yuanhong flies along the river with little effort. As long as he is careful not to bump into the river and the reefs on both sides, Li Yuanhong's road is almost smooth. However, Li Yuanhong also has some problems in the middle of the river. If Li Yuanhong had not the ability to blink, it was estimated that those waterfalls would have thrown Li Yuanhong Die in this dark river.

After more than half a day's tossing, Li Yuanhong was finally washed into the sea by the river in an inconspicuous beach. As he entered the sea, his indomitable momentum was discharged. Finally, Li Yuanhong released his nervous tension, and then drifted forward for a distance along the slowing water, far away from the coast. It was thought that after the demons could not find out, Li Yuanhong was able to find out Come out of the water, take out a rubber boat from the space, and be afraid to go up.

After a short rest and regaining his strength, Li Yuanhong takes out his walkie talkie and informs Xu Ying of his position. Then Li Yuanhong closes his eyes and quietly waits for the rescue fleet to arrive.

After a while, a UAV appeared in the sky, and then a speedboat came to pick up Li Yuanhong, who was exhausted. At this point, Li Yuanhong's single adventure journey came to an end.
