The people on the side immediately moved when they heard this, but they felt that they had not walked for long, and in the tunnel not far from them, there seemed to be a golden light floating up, followed by a figure running to the place just now.

Speaking of the living spirit in the coffin of the first bedroom just now, but the condition of this living spirit was a little sad, but it stopped on the edge of the rubble, and there was a lot of life breath left on the stone, and these life breaths were like addictive gases to fire spirits like it.

Just like the status of cigarettes among human beings, it is also an indispensable existence for their spirits, and it is also a serious addictive energy, and if it is infected by the evil breath, it will even become more ferocious, and this living spirit seems to be quite calm, and it seems to be a little better than it was in the past, is it a change in appearance after absorbing blood.

Speaking of which, this kind of life energy is also a good nourishing appearance, but the living soul is slowly improving, and it is becoming more and more terrifying, and the strength is getting more and more powerful, maybe although the hunter of the same level is an opponent of the same level in front of them, it will not have a heavy blow effect on him for a long time.

However, the people over there were absolutely unaware of the changes that had taken place long ago, and they were running wildly, and they had already burrowed into the tunnel ahead.

After running for a distance, they found that they really couldn't run, not really unable to run, if they continued to run for more than ten kilometers on the ground, it would not be a problem, but now they were all hot and dry, to put it bluntly, the air in the cave at the moment is probably a little insufficient, and the breathing volume of several of them is a bit short of supply even if they are carefully calculated.

Speaking of which, there were no such signs on the flat ground, and when the body warmed up, the limit of the body soon came, and the others crouched on the wall and gasped violently.

"It really reminds me of the long distance running experience in school before, and now I rarely have the experience of being out of breath, damn it." Xiong Tai immediately reminded on the side.

"There is not enough oxygen, even we can't carry it, let's put on an oxygen mask and move forward." Speaking of which, the oxygen mask is really the right one, otherwise this time it is really more auspicious, in a low-oxygen environment, it depends on who has a stronger adaptability, but if it is intense exercise, the body will definitely not be able to bear it first.

Although they are seasoned hunters, they should usually practice a lot when it comes to running, and some of them are still men from the army, but surviving in a low-oxygen environment for a period of time can produce a slight improvement in everything.

Speaking of which, this doesn't mean anything, after putting on the oxygen mask, the weakness of the body was suddenly pressed down by the oxygen, and the state in front of me became refreshed, and the vision gradually became clearer, and the road ahead was in front of me.

"How long will it take to get out, I think it's almost time to find a way to get out, that thing will definitely be resurrected, it can't go on like this, let's go out." McGee shouted.

"Well, I also have this idea, but I can't tell where there is an exit, now it's another step at a time, fortunately, the terrain here is not particularly complicated, we will definitely encounter some other situations if we continue to move forward, or that sentence, what you see is not seen, keep your head down and walk forward carefully little by little." Rose continued to motion, and the people on the side immediately nodded.

A few people continued to walk, and the terrain in front of them suddenly became dangerous, they did not expect that the sudden situation would be so urgent, the intersection became narrower and narrower, so they began to need to bend down and crawl forward little by little.

What's even more unexpected is that the narrow area at the end of the intersection suddenly becomes spacious, I really don't understand why the original designer used such a setting, others are at a loss to go out, and what is even more unexpected is that there is a splint at the bottom of the end, and then the bottom is empty, and the whole person immediately fell down.

And they also fell straight down, I don't know how long it took, they fell into the pool, and when they raised their heads and came out of the pool, they looked up and saw a moving splint spinning above their heads.

Then they found that if they climbed up from the wall next to them, they might be able to do so, but the part of the wall was actually made of ice, and the inner wall was still full of thin white mist on the water surface, which gave people the feeling that they really didn't know what to say, a little weird, but it was not a toxic gas, and the water was rich in freshwater, more like distilled water.

Strangely enough, the lower layer of the splint resembles a hornet's nest, and the waterhole has been violently shaken up just now, which seems to have stirred up the creatures in the hornet's nest.

It was a flying insect that emitted blue light, and it looked like a dragonfly, but it was not a dragonfly species, but a flying insect that had never been seen before, and it seemed to be a kind of insect that belonged to the category of insects, and it appeared to be quite dense, and suddenly flew densely towards the movement below the surface of the water.

Apparently the flying insect was only slightly frightened, and after a while, it flew towards the nest in a swarm again.

"It's so dangerous, the air here is very fresh, I can rest assured, I can take off my mask and breathe freely." Although the oxygen in the oxygen mask is barely enough to supply the ability to be consumed for exercise, it is a pity that in some respects this oxygen is indeed suspected of being synthesized, and the oxygen that is close to pure oxygen actually causes a great burden on the body when breathing.

"Don't worry, the air here is fresh." Speaking of which, the others immediately took off their oxygen masks, and then they sat down on the edge of the reef on the side, and after carefully observing the surrounding environment, they found that this was only a place where the incident occurred, and it can be said that the splint just now was deliberately designed in this way, if the previous opinion was not wrong, even if they returned to the top, they could only face a wall and be stunned, and they might not think that there was a way out below until they died.

"The intersection must be around here, and if you look for it, it will definitely not be so obvious, so we need to eat something and think about it, if you were the engineer who built this place, where would you design the intersection?" In fact, the design here is not too complicated, but fortunately, there is no such ominous thing as a coffin here, otherwise there may really be a problem.

Without a coffin, there would be no living souls, and it would certainly not be so easy for those living spirits to find this side, and if they searched for it with their breath, the water could see that all their scents were washed away, which was equivalent to covering their scent, and the possibility of finding them was even lower.

Speaking of the state, it is still a little confused, and after careful observation, they still found a so-called commonality, this common point is also the common point above, the propagation of sound can quickly bounce through the four walls, forming a sound barrier-like existence, even if you talk in a whisper, it is difficult to hide the consequences of whispering.
