"What''s that look in your eyes?"


    Li Yao was dazzled by Li Jialing''s eyes, but the second monk Zhang couldn''t figure out, "why do I read a strong sense of" care "in your eyes? What''s the situation?"


    "Nothing."


    Li Jialing looked back and said solemnly, "I just hope brother Yao knows that no matter what kind of road I eventually choose, and no matter what kind of person I will become, I will never forget that you are my... Family. In my heart, you are even more important than your royal highness. I sincerely treat you as my elder brother. I hope you are always safe, eh, And healthy. "


    "Is it?"


    Li yaogan received Li Jialing''s sincerity and said with a grin, "I really treat you as my younger brother. In a word, younger brother, don''t be bewitched by long Yangjun''s female devil, and don''t run into some small darkness and difficulties. In a word, we can save the world step by step. Let''s let it go first and learn to help each other when we see injustice, In short, brother Yao has confidence in you. I believe that one day you will realize the essence of Xiuzhen Avenue and become a more powerful cultivator than brother Yao! "


    "Maybe."


    Li Jialing said, "I have to walk more, look more and think more to choose the final road. Only in this way can I run all the way on my own road without looking back!"


    As they spoke, they unconsciously went to the deepest part of the town.


    This is a rock wall hundreds of meters high, but it is full of beehive like caves. The diameter of each hole is about three or five meters. Outside, there is a fence woven with vines, and inside comes the sound of "humming and chirping".


    Countless underground people carrying a lot of moss, vines and mushrooms, and even barrels of fine ore into the cave, we can see that the weight on them is very heavy, which makes their bones protrude, their tendons show, and their expressions are ferocious and painful.


    After a while, the people in the deep cave emptied the moss and vines, and came out with buckets of stinking feces. The burden was lightened, and the originally ferocious faces appeared numb.


    Li Yao and Li Jialing are both distinguished guests here. The underground people didn''t stop them from entering the cave. They didn''t even dare to make eye contact. They bowed their heads one by one and walked past them in a hurry.


    When they entered a cave at random, they saw dozens of raised rock insects.


    As expected, the rock worm is not much like a worm, but more like a fat white pig. It is only slightly slender, with a length of three or four meters and a diameter of about two meters, just like a big oval meat ball.


    It''s better to call them "rock porpoises" than "rock insects".


    Li Yao didn''t know if the rock worm had feet or claws. At least now he can''t see any organs for action. Maybe they are all covered with fat.


    This is a kind of spirit beast with extremely slow action, like a sloth, crouching in the depths of the cave and motionless like a statue. Li Yao doubts that they even have no ability to find food on their own.


    The "hum and haw" sound was not their cry, but the breathing sound from the vent on their head. These stupid and lazy spirit beasts didn''t even bother to make a half sound.


    Underground people cut up a large amount of moss, vines and mushrooms, and then mixed the ore ground into fine powder, stirred it well, and put it into the feed trough. A few rock insects swarmed around slowly. The "head" with round rolling eyes opened a cross gap, spurted out thousands of white threads, and wrapped the food into snow-white balls, Involved in the cross gap, is to complete a feeding action.


    While the rock insects were eating, the underground people bypassed them and went to the depths of the cave to collect their dark green feces. They carefully scraped every corner of the cave.


    There are also some underground people, with long handle brushes, brushing hard on the rock insects. At first, Li Yao thought that he was going to clean them up and kill them to eat. But when he looked carefully, it was not right. It turned out that the underground people were massaging the rock insects to relax!


    It can be seen that the rock worm is the only means of production for all residents in 10084 district. They have taken great pains to raise and care for the rock worm.


    Li Jialing told Li Yao that the rock worm was an excellent edible spirit animal that had been modulated by a large number of genes in the era of Xinghai Empire 10000 years ago. The earliest research was even carried out in the period of the demon beast Empire, which was good at biochemical technology.


    Rock insects can devour up to tens of thousands of the roughest food materials, including minerals containing a large number of trace elements, which are converted into a large amount of fat and protein, providing the necessary energy for human survival in the worst environment.


    The rock worm is full of treasures. It combines the genes of some special spiders and silkworms. The silk thread used to wrap food is also a good textile material. Moreover, it peels once a year. The peeled skin can also be made into a light and warm leather garment.


    In addition, the excrement of rock insects hardly needs to be refined. It is a natural fertilizer. It is suitable for the nourishment of most plants, even mushrooms and mosses. It can make wild plants domesticated into crops with soaring yields.


    It can be said that in the process of human exploration of unknown areas, as long as we bring the rock insects, we will solve the two key problems of "clothing" and "food", and lay a solid foundation for the development of agriculture.


    However, too much genetic modification has been carried out in terms of "omnivory" and "availability". The consequence of the rock worm''s desperate growth of fat and protein is that its mobility and predation ability are greatly weakened to almost zero.


    This is a kind of life born in the laboratory. On the premise of maintaining the existing characteristics, it is extremely difficult to adapt to the harsh life in the wild. It can only stay in the feeding room honestly and be fed by human beings.


    Ten thousand years ago, when the Xinghai Empire designed these underground shelters, it naturally had a set of extremely advanced and sophisticated automatic feeding equipment to ensure that the energy source of this "meat factory" continuously exported products. From the initial mating of rock worms to the final packaging of ready to eat meat in cans, the whole process did not need many workers and breeders to control.


    However, with the erosion of time, the former automatic feeding equipment has long been depleted of energy, fragmented and no longer exists, and the original knowledge of feeding rock insects has long been lost. Today''s underground people can only feed them in the most primitive way.


    Since the rock insects can grow so much meat, they naturally eat a lot. They can''t go out to look for food by themselves. They all depend on the underground people to collect mosses, tear off vines, cut down mushrooms, dig minerals, grind and mix them, and put them into the feed trough. This is a very heavy manual work. Only three or five strong men work all day long can they barely satisfy the appetite of a rock insect.


    In order to ensure that there are so many mosses, vines and mushrooms growing in the underground world, we have to continuously put the dung of rock insects into the crevices of rocks, and then carefully serve all kinds of crops. The underground world is not suitable for crop growth. Even the smallest cluster of mosses is irrigated by underground people with blood and sweat.


    Because the real automatic feeding tank has been destroyed for a long time, and the rock insects can''t adapt to the environment deep in the cave, so they have to be massaged day and night to force them to get up and move. Otherwise, the rock insects will soon grow black spots, which means that all the flesh and blood inside will be damaged and they can''t eat.


    These jobs account for 99% of the underground people and 99% of the time. It can be said that the whole 10084 area is surrounded by "rock insects".


    According to the number of stalagmites, stalagmites and caves on the cliff that Li Yaogen saw just now, he quickly calculated the ratio of the number of rock insects and underground residents. He found that compared with the population of 10084 District, the number of rock insects seems to be too much. Even if they all killed and ate meat, they could not eat so much. If we could raise a few less, wouldn''t it be much easier for people?


    Li Jialing shook his head and said that he only knew one thing, but he didn''t know the other. Just now, he said that although the underground people have worked hard to raise so many rock insects, they usually don''t want to eat large pieces of meat. It''s good to have a small piece of meat chopped up every few days and mixed it into the porridge.


    Most of the rock insects molt for three times, and after they mature completely, they have to carry them to the upper town, that is, the "four digit area" numbered between 1000 and 9999, in exchange for precious energy, civilian magic weapons and weapons.


    After all, the underground residents in 10084 area are not completely ignorant barbarians. They still retain their basic language and culture, and a small number of magic weapons and array are still in operation. They are also eager to know what the world above looks like - a lot of materials and fuel are exchanged by rock insects, but all kinds of synthetic food are popular in the world above, Rock bugs can''t sell at a high price, and three or five rock bugs may not be able to replace a standard wafer box.


    Even if they clench their teeth and don''t want any magic weapon or energy, there is at least one essential material that they have to go to the town above to buy, that is, fresh compressed air, as well as the maintenance of air circulation and filtering system components.


    Even if there is the largest and most efficient ventilation system in a town tens of thousands of meters below the ground, and fresh air is constantly introduced into the ground, it is also a very depressing and depressing world, full of all kinds of deadly toxic gases.


    Once the exhaust gas exhaled by human beings is too much depressed, it will also lead to the suffocation of all people.


    Therefore, underground residents can abandon all magic weapons, even the overhead lighting array, and become ghosts in the dark, but they can never abandon the air circulation and filtration system.


    Once the air circulation and filtration system failure, but also in time to release ultra-high compression of fresh air, for valuable maintenance time.


    No air, more terrible than no sunshine, is the real disaster.


    The residents of four digit cities and towns are determined by the fatal weakness of five digit cities and towns. The lion opened his mouth and set the price of related magic weapon components and compressed air to a very high level, so that dozens of rock worms can exchange for a small can of compressed air.


    Therefore, the residents of 10084 area work hard to grow and feed every day, not only what they wear and eat, but also the vital air for survival, even for a second!
