Yu Mo's expression was a little weird, and he didn't speak on the side.

"Did that old man come out of there?" Thinking of being stared at all the time when he was sleeping just now, Yan Luo felt creepy.

When did he appear there?

"Then there must be an entrance upstream, with the old man's physical strength, he can't go so far." Yu Mo's objective analysis.

"But we didn't ...... along the way"

"It's a trap." Yu Mo calmly interrupted Yan Luo's words: "This also makes sense, why did we walk for so long and didn't run into Xu Dongang." Because he has already gone in. ”

"But we don't know the principle of this mechanism...... Yan Luo seemed to think of something, and frantically took out the map that was originally taken out of Cheng Ru's pocket and spread it out.

The miner's lamp overhead shone on it.

"It must make sense that the red line points to the canyon, because that mechanism is in the direction of the red line." Yan Luo pointed there with his finger: "That's where we just started going down." ”

"I think I know how that mechanism works."

Quite simply, now the situation is clear.

What didn't want to enter this place was, Yu Mo.

Those who want to enter this place are Jiang Yan and Xu Dongang.

That's why Xu Dongang will give priority to going down at the beginning, giving priority to entering that place to avoid some other resistance.

And Yu Mo made up a scary story at the beginning, wanting them not to enter the canyon from the beginning.

As for that photo, it may be Yu Mo...... It could also be Jiang Yan......

In the middle of the night, Yan Luo didn't want to wait, instead of being stared at to sleep, it was better to come forward and find out.

Walking to the fast skylight, Yan Luo walked to the original place.

The old man was still sitting there, his eyes closed, and his face serene.

Perhaps, as he said, he finally saw the outside.

Now here, there is no suitable place to bury the old man, Yan Luo can only say that he is offended, and let the old man sit there and no longer disturb his peace.

Yan Luo's feet stepped on the stream, and even in the bright morning light, he could already see the scene in the stream.

Somewhere, there is a faint vortex that is not obvious.

The mechanism is here.

Yan Luo remembered the record in the diary, Cheng Xin, they came back in the middle of the night, wet.

At that time, they should have come to Hell Valley, and the wet body was not caused by avoiding Wulian as Yan Luo thought at first.

Rather, it is to enter somewhere in the valley of hell and must be launched.

Yan Luo stepped the center of the whirlpool, and a hole parted in the middle of the stream, which was an underground river.

The water of the creek flows into an underground river like a waterfall.

Not tall, only half a meter.

Yan Luo remembered that where he saw that thing before, there was also an underground river.

I don't know if it's the same with this.

Without hesitation, Yan Luo jumped in.

Fortunately, after swimming forward for a while, he felt the surface of the lake, and Yan Luo let himself float and drill out of the water.

The sight of this place made her dumbfounded.

It's a lab.

There are many transparent containers and jars on the shore, which contain many taxidermy animals.

For the most part, those animals have mutated.

At this time, Jiang Yan and Yu Mo also followed, and when they saw the scene in front of them, they both took a deep breath.

No one could have imagined that someone would build a laboratory in this place where birds don't, and moreover, it was built in such a hidden location.

Swimming to the shore and stepping on the ground with both feet, Yan Luo felt less panicked in his heart.

"You say this person, what does he want to do?" The place where Yan Luo is located is only the entrance to the entire laboratory, and there is a passage in front of them on the right.

This project must be huge.

The manpower and material resources required must be extremely huge.

And, it takes a long time.

It seems a bit strange to spend so much effort to build a laboratory in this place.

"No matter what he wants to do, this experiment of his must not be known to the world." Jiang Yan replied, his tone a little indifferent.

Walking to the passage, Yan Luo found that there was a stone door guarding it.

Jiang Yan seemed to know more about these mechanisms, he groped beside the stone gate for a while, and then he heard a click, a small stone was pushed in by him, and the stone door opened.

"Modern people don't spend so much effort to make these mechanisms, they can install an anti-theft door." Jiang Yan entered the passage, walked in front for a while, and suddenly said.

"What do you mean?" Yu Mo, who hadn't spoken for a long time, suddenly spoke.

"Meaning, this lab was built a long time ago? But those containers just now were obviously invented by modern science. Yan Luo remembered the transparent container jar of animal specimens he had seen before.

"This laboratory was built a thousand years ago, and at a certain time, it was abandoned, and then it was discovered by some people in modern times, and it was used to become the laboratory you see now." Jiang Yan explained earlier, for some reason, Yan Luo heard that his voice was a little weird, as if it was much hoarser than usual.

"A thousand years ago?" Yan Luo's first reaction was the imperial tomb, the ruler at that time was scheming for his tomb, but then he shook his head, the scene in front of him had nothing to do with the mausoleum.

"They all serve the same purpose. Although the previous people were ignorant, they also had the rudiments of scientific research, and they were in this place, probably to study the mutation process of the two weasels. Jiang Yan dodged in the left and right passages, and chose the right side of the passage.

Yan Luo followed closely: "It's just two weasels, as for it?" ”

"Perhaps, two weasels are not enough, but what they eat is very much." The passage on the right came to an end, and it suddenly opened up in front of you.

It was a huge hall, much larger than the space they had just surfaced.

Inside, it is no longer a taxidermy of an animal, but a taxidermy of a human.

Only a few containers contained people, the others were empty.

The walls of the hall are coated with a layer of fluorescent material, so you can see the surroundings even if you don't have lights.

"Why, so many containers and cans are empty?" A strange feeling rose in Yan Luo's heart, she remembered the sound in the stone she heard before, and the eye she saw before she went to sleep......

"Because they're all out." Jiang Yan turned his head, looked at Yan Luo, and said with a smile.

Yan Luo sighed in his heart, it was not Jiang Yan's face.

Yan Luo turned around and wanted to find someone else, but found that in the hall of Nuoda, only she and "him" were inside.
