The two continued along the passage.

As he walked, he carefully looked at the detection results of the life detector on the light guide lens.

This portable small life detector can detect creatures up to 200 meters away depending on the environment.

Of course, 200 meters is a situation without any obstacles. If an obstacle is encountered, this distance will rapidly decay.

If it is separated by rock and soil, it can only detect one or two meters.

"There seems to be nothing, no biological signals."

After walking for a while, He Sicheng said.

Lu Heng reminded: "Be careful, don't just look ahead, there may also be something in the rock and soil on the left and right."

"I know."

He Sicheng replied.

Then, the two continued to move forward cautiously.

In this way, the two of them walked a full two kilometers before they knew it.

Of course, not in a straight line.

In the middle of the tunnel, I also selectively changed direction and went in to have a look.

But in general, the two of them have been moving forward in the direction they started from.

Where they are now, they are at least seven or eight hundred meters away from the starting point just now.

"Looks like there's nothing here."

While observing the surroundings, Lu Heng said to He Sicheng.

He Sicheng frowned and said, "How come there is nothing? It's really strange..."

Lu Heng wondered: "Why, you still recognized that there is something in this place?"

Listening to the meaning in his words, it seems that he already knew what was going on here.

"My intuition tells me that there should be monsters here." He Sicheng replied.

"Then your intuition doesn't seem accurate. There is no life signal on the life detector now."

Lu Heng pointed to the light guide lens on the right side of the helmet and said.

He Sicheng frowned again when he heard the words, and then asked, "Would you like to stop walking forward?"

"You really don't want to die until the Yellow River." Lu Heng was speechless, "Forget it, I will give my life to accompany the gentleman and accompany you to the end."

There's nothing in this place now, so I can't stand here forever.

And if you go back, you have to walk a long way to find the rock-devouring rat.

So it's better to move forward.

Anyway, according to the topographic map just downloaded, the place in front has been explored by the strong, and it is not a dangerous area.

"Then go!"

Seeing Lu Heng agree, He Sicheng immediately raised his foot and started.

The two continued to move forward cautiously, observing their surroundings as they walked.

After walking for about 500 meters.

He Sicheng suddenly stopped and said, "No, I always feel that there is something here, why not?"

"You're just an illusion." Lu Heng looked at him and said.

After speaking, he said solemnly: "Forget it, let's not talk about this, now we have two choices, one is to go back and look elsewhere."

"The second is to keep moving forward, maybe if you walk further, you will find the Rock-Eater."

Lu Heng didn't know where the rock-devouring rats that had just escaped were in danger. It was possible that the place was behind them.

If the dangerous place was behind them, then there must be some rock-devouring rats running in the direction they were facing now.

That way, if you walk further, you might find the Rock Rat.

There is no way, we have come here now, and if we go back the same way, it will be a complete waste of time and waste a lot of time.

Of course, it is possible to go forward with nothing, and in that case, going back on the same path is the right choice.

Seeing Lu Heng asking, He Sicheng thought about it and said, "Why don't you look forward, you've already come here."

"I knew you would choose that."

Lu Heng could see that when two choices appeared at the same time, He Sicheng was more inclined to the unknown choice.

Now it is unknown to go forward, and it is known to go backward. He Sicheng chose the unknown direction without hesitation and took a gamble.

"Then let's go, hurry up and take a look. If we have nothing, we will hurry back and go back."

Lu Heng said.

Walk straight ahead for another two kilometers and you will be outside the known topographic map.

In other words, more than two kilometers is an area that has not been explored by the strong, and it is difficult to say what danger will be there.

"Walk."

He Sicheng raised his foot again and stepped forward.

The two walked all the way.

An hour later, the two of them walked for more than three kilometers, and they came to a place that was one kilometer away from the position just now.

"Damn, it's a waste of time."

He Sicheng was a little annoyed.

The proposal to go this way was originally proposed by him, thinking that there might be surprises.

As a result, there was not a single rock-devouring rat along the way, and a lot of time was wasted.

"Go, go back."

Although Lu Heng was also deeply regretful, he was saddened by the time wasted.

But things have already happened, so what's the use of complaining.

"Hey-"

He Sichang sighed and turned around with Lu Heng.

However, not long after they turned around, the passage behind them, that is, the passage they had just faced, suddenly raised a head with a large mouth of blood.

Swah—

The head of this unknown creature suddenly stretched forward and bit both Lu Heng and He Sicheng.

And at this critical moment, He Sicheng shoved Lu Heng abruptly and shouted, "Be careful!"

Bang bang!

The two collided with the rock walls on both sides of the passage, and the head passed through the two of them, biting in the air.

"What kind of monster is this?"

"Snake?"

The two were clinging to the rock wall, and after a careful look, they found that the monster attacking them seemed to be some kind of mutated snake.

And it is very powerful.

"Run, run in the direction of its tail!"

Lu Heng shouted.

Immediately after that, he supported his right hand and rushed towards the tail of this strange snake.

Now the head of this strange snake is facing the direction it came from, and the tail of the snake is facing the direction they wanted to explore before.

If you run in the direction you came from, it is equivalent to following the direction of the strange snake, and it is easy to be overtaken by the strange snake.

And if you run in the direction you just explored, it will be opposite to the direction of the monster snake. If the monster wants to chase them, you have to turn the direction first, which will delay a lot of time.

On the other hand, He Sicheng naturally understood what Lu Heng meant in an instant, and ran towards the tail of the snake with him.

sizzle—

The strange snake seemed to be too lazy to pay attention to them, and swam forward on its own, getting further and further away from them.

However, neither of them thought that the strange snake was about to give up hunting them, but wanted to detour behind them from a fork in the road.

After all, this passage is still too narrow for the snake to turn around directly.

"Fuck, this monster can't be detected by the life detector."

He Sicheng scolded while running.

Lu Heng said, "Don't worry about it, save your life first."

Hearing this, He Sicheng stopped talking and ran with all his strength.

For a while, there was only the sound of the mechanical transmission of Qi Neng armor and the sound of heavy and hasty footsteps of the two of them.

At this time, the monster had disappeared.

But this is not a good thing, because it is not known from which fork it will suddenly jump out.

It might suddenly appear at a fork in their direction and stop them.

It is also possible that when they pass a fork in the road, they suddenly jump out of the side.

In short, the disappearance of the strange snake made Lu Heng and He Sicheng feel even more pressure.

It's more stressful than coming directly to chase them.

While running wildly, Lu Heng took time to look at the topographic map on the light guide lens, and found that the boundary of the topographic map was getting closer and closer.

It is estimated that after running another four or five hundred meters, you will run outside the known area.

"Lu Heng, move on?"

He Sicheng asked suddenly, and seemed to be looking at the topographic map as well.

"You can only move forward!" Lu Heng said, "The monster must have detoured and chased us. Now we have no way of knowing whether it is on our left or right."

"So you can't choose left or right, you can only move forward."

He Sicheng heard the words and replied, "I think so too."

The strange snake didn't chase directly from behind, but took a detour to chase, so that they didn't even know which direction the strange snake was in.

So you can't change the direction of progress, you can only keep rushing forward.

This is the only safe direction.

Of course, another option is to turn back directly, return along the original path, and catch the opponent by surprise.

But the problem is that they don't know the habits of this strange snake, and they don't know what sense organs the other party relies on to identify their position.

Maybe as soon as they turned around, the strange snake immediately sensed it, and then changed direction and waited for the rabbit?

Therefore, UU reading www.uukanshu.com now the safest is to continue to run.

Only by constantly running forward can we maintain a little first-mover advantage and distance advantage.

However, if you continue to move forward, you may also encounter powerful rock-devouring rats, such as fourth-level rock-devouring rats.

But according to the nature of rock-devouring rats, as long as they don't take the initiative, they generally won't take the initiative to attack.

Therefore, the threat of the fourth-level rock-devouring rat is much smaller than that of the strange snake.

Also, after sensing the aura of this strange snake, the rock-devouring rat in front will most likely flee directly.

Therefore, if you run this way, you might not be able to run into a rock-devouring rat.

This was indeed the case. After running wildly for a while, Lu Heng and He Sicheng found that not a single rock-devouring rat could be seen, and the entire passage was empty.

Both were slightly relieved.

For now, as long as you get rid of that strange snake, it is a successful escape.

As for what to do after the escape, we will talk about it later.

"Wait, now there's another question."

Lu Heng suddenly remembered something and hurriedly said.

He Sicheng asked, "What's the problem?"

Lu Heng said worriedly: "We don't know where the end of this passage is."

The last time he and Xing Zhan entered this underground labyrinth, Chen Mingzhe and others were found at the end of a passage.

So this passage must have an end, but I don't know where the end is.

Now that I'm running all the way, I can't detect the situation ahead in advance. In addition, I have already run out of the boundary of the topographic map, and I don't know where I am at all.

If you run to the end of the passage, you can only turn back a certain way to find other forks.

What should I do if I collide with a monster head-on?

That's really only a dead end.
