Li Jialing''s face showed an indescribable complex expression and murmured: "reasonable is reasonable, but... Why every time I listen to brother Yao''s words, it''s reasonable, but when I turn around to listen to sister long''s words, it''s also reasonable. Even when I think about Wu Yingqi''s actions occasionally, it seems reasonable? You''re all right. I''m completely confused! "


    "So, you are too young, you need more experience!"


    Li Yaodao said, "what''s more, most of the time, just talking on paper and boasting, all kinds of strange things can be packaged without flaws, but the key still depends on how to do it and how to practice it.


    "I admit that the situation in the center of Xinghai is chaotic, and Xiuzhen Avenue seems to be in decline. However, it is precisely because of the chaotic situation that the black star emperor, the four election emperors and the holy alliance all check and balance each other that it is convenient for us to fish in troubled waters and rise in chaos!


    "If we go back five hundred years, and the Empire of human beings is relatively stable and monolithic, then there will be no hope at all!


    "So, give brother Yao some confidence, give Xiuzhen avenue a little confidence, believe me, this kind of fishing in troubled waters, stealing chickens, taking advantage of the fire and robbing, are all my good tricks!"


    After hesitating for a long time, Li Jialing nodded slightly and said, "I will keep brother Yao''s words in mind. Anyway, I will never be a coward or a coward!"


    Just then, they suddenly heard the intermittent but rhythmic tone from the deep of the town, like someone singing a strange tune.


    The two were slightly stunned. They looked at each other and listened to each other. Only then did they find that the tender and lively voice was the children who had just seen and climbed onto the main control crystal brain to play.


    The children never breathe as like as two peas. The performance of "intoxication" is more intense than that of adults. While clapping and singing, the old children''s songs are clapping. Perhaps the children born at that time ten thousand years ago, the children of the time, all of them had sung the same nursery rhymes at a moment''s happiness.


    Li Yao narrowed his eyes, listened for a while, and said, "that''s nice, isn''t it?"


    "Yes."


    Li Jialing was a little melancholy and in a trance. She said softly, "when I was a child, I used every second to practice and fight. I never sang any children''s songs."


    Li Yao said: "one day, you will also have offspring. They are very cute. Do you want them to live in a world without light and nursery rhymes?"


    Li Jialing was silent for a long time. He gradually clenched his fist and said, "brother Yao, let''s go deeper and see what the savages in the" dark death zone "look like."


    After checking some materials brought to the ground and finally confirming the intricate gap map, Li Yao and Li Jialing walked through a long corridor, opened the rusty gate of the refuge and came out of the field under the gaze of several fully armed underground people.


    As soon as they leave the ancient refuge, the temperature outside suddenly rises by dozens of degrees, and the air becomes more and more stuffy and stagnant, making them feel like they are in invisible magma, which will melt at any time and solidify into a part of colorful rock layers.


    Outside the shelter, there are numerous tunnels leading up, down, left, right, East, West, North and south. Li Yao rubbed the rock walls of these tunnels with his hands and found that they were smooth and there were traces of artificial polishing. They didn''t seem to be naturally generated, and there were circles of spiral lines. He knew that all the tunnels were a long time ago, maybe 10000 years ago, It''s made with a large drill truck and roadheader.


    Li Jialing told Li Yao that when the monster Dynasty and the Xinghai empire collapsed, countless demon tribes and practitioners fled to the ground. At the beginning, they naturally carried countless large underground magic weapons, and the ground drill and roadheader were the top priority.


    At that time, no one wanted to be trapped in a refuge alone. The exiles all had ambitious plans to open up countless tunnels in all directions with ground drills and roadheader, connect all the shelters together, and even rebuild a large-scale "underground Empire".


    Perhaps at the beginning, they achieved partial success. Hundreds of refuges formed a huge force to exchange materials and information to the greatest extent, so that the civilization on the ground could continue.


    But it didn''t last long. Soon, the "underground Empire" established by the demon clan and the "underground Empire" established by the practitioners discovered each other, and immediately launched a bloody and endless underground war. At that time, the practitioners just broke away from the "30000 year old dark age". Soon, they still had deep hatred for the demon clan, The demon clan also indulged in the pain of national subjugation and extermination, and there was no possibility of compromise and reconciliation.


    The intensity of that war is certainly more cruel than the strangulation of the "Starlight organization" in the British world. In the depths of the earth where there is no sunshine, drinking water and other resources, there is no winner in this war.


    The tunnels of the demons and the Terrans entangle with each other and collapse together; Both sides of the drill through the enemy''s head, track and crush the enemy''s bones; The super large tunneling system with hundreds of toothed discs could have made a bright future, but it smashed the enemy and its own civilization.


    Today, ten thousand years later, the civilization of the past is almost gone. Only these twisted tunnels and abandoned refuges, as well as the decayed corpses at the end of the tunnel and in the corner of the refuges, are left, quietly telling the tragedy of war and the cruelty of hatred.


    Li Jialing told Li Yao that with the earthquake and magma explosion in the past 10000 years, most of the tunnels have been fragmented and distorted, becoming a dead end.


    There are also many abandoned shelters at the end of the tunnel, which have nothing but corpses and Ashes - all the slightly valuable things, which have long been picked up.


    Only a few tunnels can lead to some underground caves barely suitable for living beings. Most of these caves are super large artificial bases. Originally used to accommodate the exiled civilization, they have become the habitat of savages and monsters.


    Long Yangjun has been here for a long time. He has explored the tunnels and natural fractures near area 10084. He has also carefully drawn a three-dimensional map and imported it into Li Jialing''s portable crystal brain. In addition, he has a positioning chip that can lock her coordinates in real time. He is not afraid to go the wrong way.


    These tunnels were originally "underground roads" connecting various shelters. Naturally, they are not too small. The diameter is at least three or five meters, which is enough to accommodate a fully armed soldier in crystal armor. It is not stuffy to walk.


    Both Li Yao and Li Jialing have magical powers. Even though there is no light and the air is sultry, they are still flying.


    Even if the tunnel was torn up by the earthquake, leaving only the curved narrow gaps, they could barely change the structure of their bones and muscles and squeeze through them. Since savages can pass through these gaps, they can''t be too narrow and twisted.


    After a short time, the lights of 10084 District disappeared in the dark. They seemed to have entered the rock abyss that no one had ever stepped into since the flood and famine. There was no sound around them. It was absolute silence. On the contrary, the creeping of human organs and the rushing sound of blood became very clear, and every breath became deafening.


    This is the dark death zone where savages often live.


    The two men released their psionic powers and carefully felt in each crevice of the rock strata. They found many creatures that could only be found in the ground tens of thousands of meters deep.


    There is a kind of creature that looks like both fungus blanket and moss, and even grows small umbrellas one after another. It grows in the hottest place in the crevices of rocks. What''s strange is that when they grow umbrellas and slowly open, the umbrellas will emit orange light, like small lanterns.


    Li Jialing told Li Yao that this kind of creature, which is similar to fungus blanket and moss, is called "flame flower" by the underground people. It can be traced back to the flood and famine period hundreds of thousands of years ago. It is very likely that it is the experimental life made by Pangu or Nuwa civilization - because the naturally formed life rarely has such strange characteristics.


    "Flame flower" feeds on the heat energy of the ground, and even agglomerates together to form a bacterial blanket that can move forward, like herding cattle and sheep to chase the pace of magma.


    Naturally, their body structure is not strong enough to be undamaged in the magma, but as long as the magma cools and solidifies slightly, it will become their most beautiful "Grassland", and the big "flame flower" will wrap the slightly cooled lava and suck up the heat energy.


    "Flame flower" itself is located at the bottom of the underground ecosystem, which is the food of countless insects and reptiles, thus supporting the whole complex food chain building; Moreover, they can absorb a lot of heat energy, and also greatly reduce the temperature of the ground, so that the savages can barely survive; What''s more, after absorbing enough heat energy, "flame flower" can also release a large amount of visible light, which is an indispensable condition for countless underground plants to carry out wonderful reactions similar to "Photosynthesis". Only these wonderful reactions similar to "Photosynthesis" can devour carbon dioxide and transform it into essential oxygen.


    No matter how savages evolve, they can''t evolve into anaerobic life without oxygen. In other words, without "flame flower", the whole underground ecosystem will collapse.


    It is said that there are many top scholars in the human Empire who want to understand the mystery of "flame flower" - this primitive fungus with simple structure and ancient form, seems to be a transitional form between life and non life, and it has been regulated by the ancient civilization such as Pangu and Nuwa. The myriad mysteries contained in it are really beyond the grasp of human beings at the moment.
