Global Invasion: Only I Know the Future

However, just to be on the safe side, the two still tested the third hole, which was the same as the first hole, and no wind came out of it.

In other words, there is no air circulation in the first hole and the third hole.

The two extinguished the candles, and then glanced at each other, feeling very excited.

Then the two went directly to the second cave entrance. When they walked into the cave entrance, they found that the cave entrance was similar to the way they had come before.

The road is very wide, but there is no danger, and the entrance of the cave is very straight. If they feel lost, they can immediately return to the same road.

It doesn't affect them to move on, it seems that they have chosen the right path.

But at this moment, they suddenly heard a few strange business calls.

The two stopped and looked at each other again. Chen Jiannan was a little surprised when he heard the strange voice, "Saint, did you hear any strange voice?"

Wu Tianyu also nodded, "I heard it!"

"There won't be any beasts in this cave, right?"

"Probably not, because there are no wild beasts in the mountains near our village, let alone in this cave."

"But this sound sounds like a sound from some mechanical bearing."

"Mechanical bearing?" The saint Wu Tianyu was taken aback, "This cave has existed for thousands of years. What do you mean, what mechanisms are there in this cave?"

It is really incredible that people who have lived for thousands of years can invent this kind of coupler with bearings.

However, the wisdom of the ancients should not be underestimated, and they decided to be cautious.

Ever since, the two of them slowed down their pace, and looked around every step they took to see if there was anything coming out.

Just as the two of them went deeper into the cave, Chen Jiannan's cold hairs suddenly stood on end, and he quickly moved the saint Wu Tianyu aside.

Wu Tianyu was also taken aback by Chen Jiannan's sudden actions. He was about to ask what happened, but he heard whistling sounds coming from his ears.

I saw a bunch of arrows shooting out of the wall, and the place where these arrows landed was exactly where she was standing just now.

A few seconds later, the arrow stopped, and Wu Tianyu was still in shock.

However, Chen Jiannan frowned, confirming that the arrow mechanism had stopped, and slowly walked to the side of these landing arrows.

Wu Tianyu came back to his senses and followed. The two of them squatted beside the arrows and looked at these arrows that were still shining with coldness in surprise.

Unexpectedly, these arrows are all made of iron, each one is extremely sharp, and there is no rust.

Moreover, each arrow was deeply inserted into the ground, which shocked Chen Jiannan, "This arrow mechanism should have been repaired when the cave was just excavated, which means that these arrows already exist. Thousands of years."

"It's unbelievable that they can still be so sharp for thousands of years without rust." Wu Tianyu also felt a little miraculous. These arrows are well preserved, as if they were new.

If she hadn't known that no one had entered this cave, she would have wondered if someone sneaked in and pressed the mechanism last night.

Chen Jiannan pulled out an arrow, looked at it twice, and then threw it on the ground, "It seems that there is a mechanism in this cave. I am very curious about the mechanical craftsmanship of human beings thousands of years ago. This mechanism looks very complicated. , and we don’t even know how it was triggered, it’s really unbelievable that humans could achieve such craftsmanship thousands of years ago.”

"It seems that we have to be careful in the future. There must be a lot of these traps. We just triggered the first trap."

Chen Jiannan nodded, "Let's move on, and you will follow behind me."

Generally speaking, the trigger mechanism must be triggered by the person who walks in the front. It was Wu Tianyu who walked in front of him just now that made these mechanism trigger.

Saying that, the two stood up and continued to set off, not being frightened by the mechanism in front of them.

However, when the two walked forward for more than ten minutes, they did not find any mechanism triggered by them again.

Could it be that there is only one organ in this cave?

But even if there is only such a mechanism, it is reasonable, because only such a mechanism can make the intruder die without a place to bury him.

If I hadn't reacted quickly just now, both of them might have been hit by arrows.

Such a dark cave, and such a ghostly trap, ordinary people will definitely be shot when they enter.

Although he advanced safely for more than ten minutes, Chen Jiannan's heart still did not relax, and he still set off vigilantly forward.

But at this moment, the two suddenly heard the sound of gurgling water, which surprised them both.

Could it be that there is still a stream in this cave, and the water is still flowing from the sound. Could it be that this cave also leads to the outside world?

Hearing the sound of running water, Chen Jiannan hurriedly took Wu

Tian Yu rushed towards the direction of the flowing water.

But when they came to the so-called creek, they found that it was actually a small circular pool.

The design of this small pool is very strange, like the Penrose steps, there is no starting point, no matter where the water in the pool flows from, it will eventually return to the starting point.

However, the water inside seems to be not ordinary water, but mercury, which emits silver light and flows in the pool. All they heard was the sound of this mercury flowing just now.

Seeing the mercury, Chen Jiannan also panicked, "Saint, cover your mouth and nose quickly, be careful of mercury poisoning."

"Okay, but how do we get there?"

This is a circular pool of mercury, which happens to be blocked in the middle of the road. If you rush over with assistance, you can jump onto the platform in the middle of the circular mercury pool.

But when you reach the middle platform, you don't know if you can jump over it again.

But Chen Jiannan was still ready to try, so he looked at Wu Tianyu, "Saint, how is your jumping ability?"

"You said you were going to jump over?"

"Yes!"

"But this pool of mercury is so wide, how do we jump over it?"

"Well, I'll carry you on my back, and I can promise to jump over."

Wu Tianyu knew that now was not the time to hesitate, but as a saint, she could not have physical contact with other men.

But thinking of being dragged by Chen Jiannan just now in order to avoid the rain of arrows, he broke the precept long ago.

Chapter 308 Mercury Pond

So she nodded, "That's fine, but wait a minute."

Wu Tianyu said, squatting down, found a stone, and threw it to the platform in the middle of the circular mercury pool.
