Li Jialing showed an indescribable complex expression on his face, and murmured: "It makes sense if it makes sense, but... why do I always hear what Brother Yao said make sense, but it makes sense when I turn around and listen to what Sister Long said. Even occasionally, I think it makes sense if the Black Star Emperor Wu Yingqi is doing? You are all right, I am completely confused!"

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

Li Yao said, "What's more, many times, just talking on paper and talking big, all kinds of strange truths can be packaged without flaws, but the key is still to look at how to do it and how to practice it."

"I admit that the situation in the Central Sea is now in chaos, and the Avenue of Cultivation seems to be very declining, but because of the chaotic situation, the Black Star Emperor, the four electoral emperors and the Saint Alliance members all checked and balanced each other, so that we can take advantage of the chaos and rise up!

"If we retreat five hundred years and the real human empire is relatively stable and iron-clad era, that would be completely hopeless!

"So, give Brother Yao some confidence and give the Tao of Cultivation. Believe me, this kind of trick of stealing and taking advantage of the situation is my best!"

Li Jialing hesitated for a long time, nodded slightly, and said without comment: "I will keep Brother Yao's words in my heart. In any case, I am definitely not a coward, nor will I be a coward!"

At this moment, the two of them suddenly heard intermittent but extremely rhythmic tones coming from deep in the town, as if someone was singing a song with strange tones.

The two were slightly stunned, looked at each other, listened quietly, and realized that the tender and lively voice was the children who had just seen crawling onto the main control crystal brain and playing.

Children have never breathed such fresh air, and the performance of "intoxicating oxygen" is more intense than that of adults. While "giggling" and laughing, they clapped their hands and sang ancient children's songs. Perhaps the children born at that time were 10,000 years ago, and now all the ancestors of everyone sang exactly the same children's songs during a moment of joy, right?

Li Yao narrowed his eyes, listened for a while, and said, "It sounds so nice, right?"

"yes."

Li Jialing was a little melancholy and dazed, and said softly, "When I was a child, I spent every second on practicing and fighting, and I never sang any nursery rhymes."

Li Yao said: "One day, you will have descendants, chubby and cute little guys. Do you want them to live in a world without light and children's songs?"

Li Jialing was silent for a long time, and gradually clenched his fists and said, "Brother Yao, let's go deeper underground and see what the savages living in the 'dark death area' look like."

After checking some supplies brought to the ground and finally confirming the intricate gap map, Li Yao and Li Jialing walked through a long corridor. With the attention of several fully armed underground people, they opened the rusty refuge gate and came to the wild.

As soon as they left the ancient shelter, the temperature outside suddenly increased by dozens of degrees, and the air became more stuffy and stagnant, making them feel as if they were in invisible magma, which would melt at any time and solidify into various shapes and parts of colorful rock formations.

The shelter is well connected, and there are countless tunnels leading up, down, left, left, east, west, south and north. Li Yao rubbed the rock walls of these tunnels with his hands. He found that the traces of smooth and artificial polishing were not like natural generation, and there were circles of spiral patterns. He knew that all the tunnels were made a long time ago, perhaps ten thousand years ago, with large marble drilling trucks and boring machines.

Li Jialing told Li Yao that when the Demon Beast Dynasty and the Star Sea Empire collapsed, countless demon clans and cultivators fled underground. At the beginning, they naturally carried countless large magic weapons dedicated to the underground, and the ground drilling carts and excavators were the top priority.

At that time, no one wanted to be trapped in a shelter alone. The exiles all had ambitious plans to use timber drilling trucks and boring machines to open up countless tunnels, connect all shelters together, and even rebuild a huge "underground empire".

Perhaps at the beginning, they achieved partial success, with hundreds of shelters forming a huge force, able to exchange materials and information to the greatest extent and continue the civilization on the ground.

But the good times did not last long. Soon, the "underground empire" established by the demon clan and the "underground empire" established by the cultivators discovered each other and immediately started a bloody storm. The endless underground war at that time had just broken free from the "30,000-year dark age". Not long after, there was still a deep hatred for the demon clan, and the demon clan was also addicted to the pain of the country's destruction and the tribe was destroyed, and there was no possibility of compromise or reconciliation.

The tragic level of that war is definitely a hundred times more cruel than the "Starlight Organization" strangle battle under the land of the Weiying Realm. In the depths of the underground lacking sunshine, drinking water and other resources, this war is destined to have no winner.

The tunnels of the demon clan and the human clan were entangled and collapsed together; the ground drills on both sides drilled through the enemy's heads, and the tracks crushed the enemy's corpses; the super-large excavation system with hundreds of tooth plates could have created a bright future, but it shattered the enemy and shattered its own civilization.

Ten thousand years later, the civilization of the past is almost destroyed, leaving only these twisted tunnels and abandoned refuges, as well as the corpses rotten into ashes at the end of the tunnel and in the corners of the refuge, quietly telling the tragic war and the cruelty of hatred.

Li Jialing told Li Yao that with the past ten thousand years of earthquakes and magma eruption, most of the tunnels were fragmented and distorted, turning into dead ends.

There are also many tunnels at the end of the abandoned shelter, where there are nothing of little value except corpses and ashes, and they have long been picked up.

Only a very small number of tunnels can lead to some caves deep underground that are barely suitable for living things. Most of these caves are artificially dug super-large bases. Super towns that were originally used to accommodate exiled civilizations have now become habitats for savages and monsters.

Long Yangjun has been here for a long time, and has explored the tunnels and natural cracks near District 10084 clearly. He also carefully drew a three-dimensional map to introduce them into Li Jialing's portable crystal brain. In addition, the positioning chip that can lock her coordinates in real time, so he is not afraid of taking the wrong path.

These tunnels were originally "underground roads" that communicated between various shelters, so they were naturally not too small, with a diameter of at least three or five meters, which was enough to accommodate a fully armed soldier wearing crystal armor and fully armed. He was not very frustrated when walking.

Li Yao and Li Jialing are both people with supernatural powers. Even if there is no light and the air is stuffy and hot, they still have a flying step.

Even if the tunnel was torn apart by an earthquake, only the winding and narrow gaps were left, they could barely change the structure of their bones and muscles and squeeze over them, and since savages could pass through these gaps, it would be impossible to be too narrow and distorted.

After a while, the lights in Area 10084 had long disappeared into the darkness. They seemed to have entered the rock abyss that no one had ever been involved in since the prehistoric times. There was no sound around them, and there was absolutely dead silence. Instead, the wriggling of human organs and the rushing blood became particularly clear, and every breath became deafening.

This is the dark death area where savages often move.

The two released their psychic energy, and carefully sensed it in each rock slit, and discovered many creatures that could only be discovered under the ground tens of thousands of meters deep.

There is a kind of creature that looks like a mushroom blanket, a moss, and even grows small mushroom umbrellas, growing in the hottest places in the cracks of the rock. What’s strange is that when they grow mushroom umbrellas and bloom, the mushroom umbrellas will emit orange light, like small lanterns.

Li Jialing told Li Yao that this kind of creature similar to bacterial blankets and moss was called "flame flowers" by underground people. It can be traced back to the prehistoric era hundreds of thousands of years ago. It is very likely that the experimental life modulated by Pangu or Nuwa civilizations was naturally formed, and rarely had such strange traits.

"Flame Flowers" feed on the underground heat energy, and even gather large groups of them together to form a fungal blanket that can move forward, chasing magma like grazing cattle and sheep.

Their body structure is naturally not strong enough to be completely unscathed in the magma, but as long as the magma cools down slightly, it becomes their most plump "grass". Large balls of "flame flowers" will wrap the slightly cooled lava and suck the heat energy in it without leaving any drops.

The "flame flowers" itself is located at the bottom of the underground ecosystem, and are the food of countless insects and reptiles, thus supporting the entire complex food chain building; and they can absorb a large amount of heat energy, which greatly reduces the temperature underground, so that the savages can barely survive; more importantly, after absorbing enough heat energy, the "flame flowers" can also release a large amount of visible light. These visible light is an indispensable condition for countless underground plants to carry out wonderful reactions similar to "photosynthesis". Only these wonderful reactions similar to "photosynthesis" can swallow carbon dioxide and convert them into essential oxygen.

No matter how the savage evolves, it is impossible to evolve into an anaerobic life without oxygen. In other words, without the "flame flowers", the entire underground ecosystem will collapse.
