Deep in the human soul lies an instinctive fear of darkness, and to explore the darkness is to explore hell.

Not every section of the leyline passage is smooth and smooth, and sometimes it is wide enough to run through large cars. Sometimes it is so narrow that the passage has to be dug out by hand. In some places, there are long underground waterways that can only be swam through by feeling. The digging process is arduous and sometimes even despairing. But the most frightening thing is to feel the warm current in the dark water and find a passage. In the darkness, it seems that there is always an unknown terrible thing observing itself.

Being in a dark and cramped environment for a long time can cause people to feel fear, and this journey of exploration is undoubtedly a great test of spiritual will. Fortunately, the grandfathers are all very people, even in such an environment, they still maintain a calm mind and overcome difficulties again and again.

The so-called Qianli Lantern is a luminous gem that can store the light source, and it is not a mythical object that can be used infinitely in the legend, so it also needs to be regularly charged by the light source from the outside. The latter is a digging tool developed by the predecessors of the Baomen, which is worn on the hand like a tiger's claw, which can quickly dig out the passage and can also be used as a melee self-defense weapon.

Comparatively, escaping from the dungeon is much easier than digging deep to find the entrance, as the initial journey involves a long part of the dungeon's artificially dug passages. The groping process can be greatly saved. It only took a few days for Evil to escape last time, but this in-depth exploration is like a blind man touching an elephant, and it is estimated that it will take longer to grope deep underground by feeling.

The three of them are well prepared, and the items they carry with them are nutritional pills that can sustain their bodies for two months, and if they can't find a way to enter the dungeon within a month, they will immediately return the same way.

On the tenth day of entering the deep darkness of the underground, the friction power generation device that he carried with him was ineffective due to the flooding, and he could only rely on his feelings to grope his way forward in the darkness for the rest of the journey. Li Muye's pair of night eyes played a great role at this time. So he changed to Brother Ono and dug a hole with his bare hands in front of him.

On the fifteenth day they encountered a muddy underground swamp and had to trek through the mud at nearly fifty degrees for two days. And it was found that the oxygen in the air had thinned to unsustainable levels. Even if all three of them have the ability to control their own consumption, there is also a limit to what they can bear. Li Muye was also able to use his telekinesis to collect the abundant Yuan Qi in the leylines to balance his state, while Evil Lai and Bai Qi had to start using spare oxygen cylinders.

In the leyline channel, you can occasionally encounter a special lichen plant, and the evil came last time so it was able to escape and ascend to heaven, and it was by relying on this thing to replenish physical exertion.

After tasting it, Li Muye found that although this thing had a faint sulfur smell, it was almost equivalent to a crystalline Yuan Force substance, which was easily absorbed by the body. After eating, you will feel a little dizzy, similar to the feeling of being drunk with oxygen, but it can make the body enter a state of internal circulation, and it seems that the eyes are much brighter. After eating evil and white rising, the need for oxygen will be greatly reduced.

When they first entered the leyline passage, they had plenty of supplies and didn't think about collecting this thing at all. Although he had eaten it before, his perception at that time was much weaker than now, and he couldn't perceive the beauty of this thing. And instinctively search along paths that are more likely to produce such plants.

On the thirtieth day, the servants still did not find a passage that could be determined to be the dungeon, but because they had more lichen plant reserves, Li Muye decided to continue to explore further. At this time, Brother Ono was already immersed in an indescribable feeling, and he was in a state of high tension all the time, making his mental perception more and more acute, and his mental power extended out of his body to explore the surrounding situation.

Evil Lai and Bai Qi are overly dependent on this plant, and even have a hallucinogenic addiction. Sometimes sober, sometimes confused, and have no concept of time. Like two hypnotized people, following Li Muye in a half-asleep state. Compared with the two, Bai Qi can be slightly more awake, which shows that the two teenagers who used to go hand in hand are now in different directions.

On the fortieth day, the servants suddenly came to a very spacious place, and the oxygen in the air suddenly became abundant, and even a little spot of light appeared on the stone wall, and there was a little visibility. There are a large number of lichen plants growing here, but the purity is many times worse than that of the one that grows in the dark environment, and there is even a feeling of gnawing on the plant in the mouth, and there will be a lot of residue left after chewing.

Maybe it's because of the contact with the outside world, and the physical properties of this thing are complicated, so there is such a phenomenon.

The oxygen-rich environment made Evil Lai and Bai Qi gradually regain their senses, but Li Muye regretted to find that the previous feeling of being sharp and under control was fading. However, the mental power is undoubtedly much stronger than before entering the cave, and the three fingers that Wu Shidong suggested that he deliberately exercised have been sharpened by these days of excavation, and they are obviously more tenacious and powerful than before.

Just as the servants were about to split up to explore the vast space, a dull loud noise suddenly resounded throughout the space. The three uncles and nephews were surprised and hurriedly followed the sound to look over, only to see that the source of the sound was above the side of this space, and a large hole suddenly appeared, and a strong air flow erupted in, and the temperature in the entire space rose rapidly. It lasted about two minutes, and the hole suddenly closed.

When the hole spewed hot air, there were many bright spots that were visible to the naked eye and could hardly be seen by ordinary people, which greatly improved the visibility in this space in a short time. For Evil Lai and Bai Qi, it is considered to have reached the point where they can't see their fingers, although it is still not up to the mark, but it is still not the same as the complete darkness of the previous one. In Li Muye's eyes, such visibility is enough to fully give full play to the advantages of the night eye.

Li Muye walked closer to observe under the heat, and found that the opening and closing of the hole was smooth and flat, which seemed to be some kind of artificial material, but the probe tried to dig it, but it did not move. I wanted to dig it with Qingyun Kazuki, but after a little thought, I decided to wait a little longer. After another half hour or so, the hole suddenly opened again, and the hot air that had been sprayed for two minutes was quickly closed again, still at the same rhythm as before.

It looks like this is supposed to be an exhaust outlet for the dungeon's air circulation system.

Li Muye made a judgment and secretly breathed a sigh of relief, finally finding a way.

The passage that escaped from the dungeon before the evil came was a similar one, but it was much closer and wider than the one in front of me.

After forty days of arduous trekking, the servants did not have the heart to care whether the passage was spacious and bright, the oxygen here was abundant, and the visibility was much better, but after all, it was not a place to stay for long.

The vent opens about every half hour, expel hot air and then close within two minutes. When exhausting, the heat hits the face, the heat is fierce, and anyone who is facing it for a long time will be burned. So the only way to do this is to break it open with force when the hole is closed, and then pass through it within half an hour......

PS: There is another chapter in five minutes, and my eyes feel much better today, and I did overuse my eyes a while ago.
