There is an instinctive fear of darkness hidden deep in the human soul. To explore darkness is to explore hell.
Not every section of the leyline passage is smooth and smooth. Sometimes it is wide enough to allow large vehicles to pass through it. Sometimes it is so narrow that passages have to be dug out by hand. In some places, there are long underground waterways, and you can only swim through them by feeling. The process of digging is arduous and sometimes even frustrating. But the most terrifying thing is sensing the warm current in the dark water to find a passage. There seems to always be an unknown and terrifying thing observing me in the darkness.
Being in a dark and cramped environment for a long time, people will involuntarily feel fear. Such a journey of exploration is undoubtedly a huge test of spiritual will. Fortunately, the three of them are extraordinary characters. Even in such an environment, they still maintained a calm mind and overcame difficulties time and time again.
Evil came to rely on the two rare objects of the Holding Treasure Gate, the Qianli Lamp and the Land-grabbing Tiger to clear the way. The so-called Qianli Lamp is a luminous gem that can store light sources. It is not a legendary magical object that can be used infinitely, so it also needs to be controlled regularly. The external light source fills in. The latter is a digging tool developed by the seniors of Jiubaomen. When worn on the hand, it looks like a tiger's claw. It can quickly dig out passages and can also be used as a close combat self-defense weapon.
Comparatively speaking, the process of escaping from the underground city is much easier than exploring in depth to find the entrance, because there is a long section of the initial journey through artificially dug passages in the underground city. It can greatly save the process of exploration. It only took a few days for Evil to escape last time, but this time he was exploring in depth, like a blind man feeling an elephant, groping his way deep underground based solely on his feelings. It was expected to take longer.
The three of them were well prepared. They carried with them nutritional medicines that could sustain their bodies for two months. If they could not find a way into the dungeon within a month, they would immediately return the same way they came.
On the tenth day after entering the deep and dark underground, the friction power generation device that I carried with me lost its function due to water intrusion. For the rest of the journey, I could only rely on my senses to grope my way forward in the darkness. Li Muye's pair of night eyes played a big role at this time. So it was Brother Ono who dug the hole with his bare hands in front.
On the fifteenth day, they encountered a muddy underground swamp and spent two days trudging through the mud at nearly 50 degrees Celsius. And it was discovered that the oxygen in the air had become so thin that it was unsustainable. Even though the three of them have the ability to control their own consumption, they still have their limits. Li Muye can also use his mind power to collect the abundant Yuan Qi in the earth's veins to balance his own state, while E Lai and Bai Qi have to start using spare oxygen bottles.
In the earth channel, you can occasionally encounter a special lichen plant. The reason why you were able to escape and ascend to heaven last time was because of this thing to replenish your physical strength.
After tasting it, Li Muye found that although this thing had a faint smell of sulfur, it was almost equivalent to a crystalline elemental substance, which was easily absorbed by the body. You will feel a little dizzy after eating it, similar to the feeling of being drunk with oxygen, but it can put the body into a state of internal circulation, and your eyes seem to be much brighter. After eating Erai and Baiqi, the need for oxygen will be greatly reduced.
When they first entered the earth channel, the three of them had plenty of supplies and had no idea of collecting these things. Although he had eaten it before Evil came, his perception at that time was much weaker than it is now, and he could not realize the beauty of this thing. After Li Muye personally tasted it and discovered the benefits of this thing, the three of them tried their best to collect this kind of lichen. plant. And instinctively search for paths that are more likely to produce such plants.
On the 30th day, the three of them still could not find a definite passage to the underground city, but because they had more lichen plants in reserve, Li Muye decided to continue exploring in depth. At this time, Brother Ono was already immersed in an indescribable feeling. He was in a state of high tension every moment, which made his mental perception become more and more acute. His mental power extended out of the body to explore the surrounding situation. Handy.
Erai and Baiqi even developed a hallucinogenic addiction due to their over-reliance on this plant. Sometimes I am awake, sometimes I am confused, and I have no idea of time. Like two hypnotized people, following Li Muye in a half-dream and half-awake state. Comparing the two, Bai Qi can be seen slightly more clearly when he is sober. From this, it can be seen that the two teenagers who once went hand in hand are now in different directions of development.
On the fortieth day, the three of them suddenly came to a very spacious place. The oxygen in the air suddenly became richer, and even spots of light appeared on the stone wall, giving them a little visibility. A large number of lichen plants grow here, but the purity is many times worse than that grown in the dark environment. It even feels like chewing plants in your mouth, and after chewing, there will be a lot of residue left.
Perhaps due to contact with the outside world, the physical properties of this thing have become complicated, so this phenomenon occurs.
The oxygen-rich environment allowed Er Lai and Bai Qi to gradually regain their sanity, but Li Muye regretfully found that the sharp and sharp feeling before, and the feeling of being in control of everything was fading. However, the mental power is undoubtedly much stronger than before entering the cave. The three fingers that Samurai Dong suggested that he specially trained after these days of digging are obviously stronger and stronger than before.
Just when the three of them were about to explore this vast space separately, a dull loud noise suddenly resounded throughout the space. The three uncles and nephews were surprised and quickly looked over at the sound. They saw that the source of the sound was just above the side of the space. Suddenly, a large hole appeared. Strong air flow spurted in, and the temperature in the entire space rose rapidly. It lasted about two minutes, and the hole suddenly closed.
When the hole sprays hot air, visible to the naked eye, many bright spots that are difficult for ordinary people to see are sprayed in, which greatly improves the visibility in this space in a short period of time. For Eilai and Baiqi, it can be said that they have reached the point where they can't see their fingers. Although it is still not up to standard, it is still completely dark compared to the former. In Li Muye's eyes, such visibility is enough to fully utilize the advantages of Night Eyes.
Li Muye braved the heat and walked closer to observe. He found that the opening and closing of the hole were smooth and flat, and seemed to be some kind of artificial material. However, when he tried to dig out with his hands, it did not move at all. I originally wanted to use Qingyun Kanyue to dig it, but after a moment's thought, I decided to wait a little longer. About half an hour later, the hole suddenly opened again. Still following the previous rhythm, the hot air sprayed for two minutes and then quickly closed.
It seems that this should be an exhaust outlet of the underground city's air circulation system.
Li Muye made a judgment and secretly breathed a sigh of relief, finally finding a way out.
Before the evil came, I took a similar passage to escape from the dungeon, but that passage was much closer to the surface than the one in front of me, and it was also much wider.
After forty days of arduous trek, the three of them no longer care about whether this passage is spacious and bright. There is plenty of oxygen here and the visibility is much better, but after all, it is not a place to stay for a long time.
That exhaust vent opens about every half hour, expels hot air within two minutes and then closes. When exhausting, the hot air hits your face, it's so fierce that anyone who faces it head on for a long time will get burned. So we can only use force to break open the hole when it is closed, and then get through within half an hour...
PS: There will be another chapter in five minutes. My eyes feel much better today. I did overuse them a while ago. (End of chapter)
