"And then?"

"After 100 years of peace and quiet in the underworld, the rulers began to become emboldened, believing that as long as humans did not return to the surface and did not affect the development of the surface, there should be no more catastrophic butterfly effects. On the other hand, pressure from the people also made it difficult for the rulers to sleep. Eventually, the ruler issued a new policy to further expand the underground. Since then, the underworld has been endlessly exploring. ”

The screen switches again, and countless humans drive one machine after another to dig underground, crushing and condensing the excavated rocks to make sturdy new bricks, which are used to build houses, buildings, roads, and so on.

"After another few hundred years, humans have dug 20,000 meters into the ground. At this time, the number of human beings has reached tens of billions, and the area of the underground world has increased dozens of times, and will even approach the surface area. The Underworld is divided into 10 levels, with the lowest layer being 20,000 meters underground. But humanity is still not satisfied, and greedy humans continue to dig down. In fact, the temperature below 20,000 meters underground is already very high, and the environment is difficult to modify, and humans cannot survive here without the help of tools. ”

"So humans continue digging when there's no longer a need to go down?" Tianpeng asked.

"That's right." A gem suddenly appeared in the elder's hand.

It is a golden-yellow gemstone that looks a bit like gold, but is more dazzling than gold.

"What kind of gem is this?" Xiao Jiangwei knew that this was a hologram, but because she liked it too much, she couldn't help but raise her hand and touch it.

"This is a golden gemstone, extracted from golden yellow ore. Humans have discovered this ore 20,000 meters underground, and it has amazing powers. Studies have shown that jewelry made of golden gemstones can prolong the life of the wearer if worn on the body for a long time. There are many elderly people who have lived to the age of 100 because they have worn this gemstone for a long time, and for a time, the value of the gemstone has continued to increase, and it has become a sacred object sought after by everyone. In order to get more gems, humans frantically dug into the ground, digging all the way up, and I don't know how deep they dug, and disaster struck. ”

"Disaster? Could it be ......" Tianpeng suddenly understood something.

"Is the end of the world breaking out?" Li Ming also guessed.

"Somewhere, somewhere deep underground, there are superbugs, and the bacteria are parasitic with the magic virus. Humans are so greedy that they accidentally release those superbugs while mining stones. Those bacteria were the first to infect the miners, and the vast majority of miners were eroded in their brains, lost their memories and consciousness, and began to eat anything they could eat, including humans. And the humans who have been bitten will be infected and mutated into those crazy people in a few minutes or so, we call them Kiel, and you landers are used to calling them zombies. ”

"I really didn't expect that this is the origin of the apocalyptic virus." Jiang Hao was shocked.

"But why is there this virus deep underneath the earth? Did the primordial universe have it too? Tianpeng asked.

"The underground of the primordial universe has also been explored, but only to obtain scarce metal resources, not to explore the underground world. At that time, human beings also operated below 20,000 meters underground, and did not find any Jinlong ore. ”

"Is it the butterfly effect again?" Tianpeng muttered to himself.

"And then?" Jiang Hao continued to ask.

"Then came the spread of the crisis, from the tenth layer of the underground, all the way up to the first layer of the underground." The elder replied.

"Don't the Underworld people have powerful tools? Why didn't the crisis get under control? ”

"Because the earth is a unified country, the rulers forbade any civil weapons in order to maintain their dominance. And because it has been very peaceful for hundreds of years, there have been some armed conflicts in only small areas. Overall, the weapons of the underworld have become very backward, and they are unable to stop the crazy Kiel. ”

The screen jumps again, and everyone sees those Kiel (zombies) frantically attacking humans, blood splattering wildly, and flesh foaming everywhere.

Ordinary people and police officers have no decent weapons at all, they are like fish on a knife board, brutally gnawed by zombies. As for those armies, they have more powerful weapons than submachine guns and machine guns. An army of 1,000 people can easily torture and kill tens of thousands of zombies.

However, the army had too few weapons, and so did the number of soldiers. And the zombies, relying on their numerical superiority and a frenzied energy, forced their army to retreat.

"But after all, the underground world is different from the land world, there are ten layers underground, and the number of connecting channels between each layer is limited, so Kiel's diffusion speed is controlled. At the same time, the humans in the first few layers of the underground began to quickly whip up weapons and gradually take control of Kiel. But ......"

"There's no way to control it, because in fact, the air is also a way of transmission." Jiang Hao said.

"That's right, no one thought that there were also pathogenic bacteria in the air, especially 60 days after the outbreak of the crisis, all the ordinary humans in the upper layers of the underground have mutated and bitten the people around them. In this way, the crisis swept through the entire underground world very inexorably. ”

"It's the same as on our land, except that in 30 days, deadly bacteria have swept the world." Jiang Hao said.

"The humans at the top were already panicking, clamoring to carve out the passage with their tools and flee to the surface. But the rulers didn't want these viruses to spread to the surface, so they brainwashed the people and even suppressed unrest. ”

"I didn't expect the rulers to be so conscious?"

"You can't say that, it's airborne, after all. Once this passage is opened, superbugs will surely spread to the surface. ”

"And what about later? What happened to the humans of the underworld? Tianpeng asked.

"Humanity is not extinct, all the surviving humans have become evolutionarily successful new humans, their combat effectiveness has been unprecedentedly enhanced, and they have established bases in various regions. Although the number of human beings is less than one-tenth of the number of Kiel, human beings have high intelligence, and some strong people stand out and become people's heroes, and they lead human beings to survive, become stronger, and fight back. ”

"It's like the world on our surface." Reverse Scale said.

"Humanity has survived, but the originally unified underworld has been divided. Humanity is no longer united, they are kings of land, and they are self-respecting. Over time, the underworld has formed a variety of states, and they have been divided and merged. Before you know it...... 220,000 years have passed in the underworld...... The people of today call that crisis the judgment of the apocalypse. The elder sighed.

In other words, less than 1,000 years after the establishment of the underground world, the Apocalypse Judgment took place, and since then, 220,000 have passed. It's terrible, that's 220,000. The history of civilization in the surface world is only five or six thousand years, and the gap is too great. Jiang Hao said with emotion.

Reverse Scale felt very puzzled: "It's been 220,000 years, why hasn't your life changed much?" And, don't you really want to go to the surface? ”

"You're right, 220,000 years is a long time, and humans have long forgotten about the butterfly effect. There are countless people who want to leave the underground and go to the surface, and the surface world has become the vision of the people underground, who want to see the real blue sky, white clouds, and sea, rather than images simulated by electronic machines. ”

"But if you go to the surface, won't it trigger the end times?" Liming asked.

"You think it's the end times? The Apocalyptic Judgment has made all living things evolve, and the lifespan of human beings has become longer, this is the rebirth of all things, how can it be called the end times? ”

"Hey, you're being too selfish, aren't you? Why is it not called the end times? 90% of humans will turn into zombies, and countless people are dying every day. Liming's temper went up slightly.

The elder also felt Liming's anger and apologized, "I'm sorry, I owe it to me. From your point of view, it can indeed be called the last days. ”

"From your point of view, it's also the end of the world, everyone watched the image just now, those Kiel were crazy about killing humans, blood all over the ground, madness all over the ground." Li Ming continued.

"At that time, it was the last days. But now people only think that it is only a long history, and we are all grateful for the Apocalypse Judgment, because it is because of it that human beings have become extremely powerful, and the life expectancy has generally reached about 150 years, and some can even reach more than 200 years......"

"You old man, is it true that you have released the virus in the surface world now?" Li Ming suddenly became very excited.

Tianpeng immediately grabbed Liming and persuaded: "Liming, calm down, we are now in someone else's territory." ”

"However, I suspect that they put the virus on the surface."

"Calm down, don't talk nonsense, please." Tianpeng tried his best to persuade Li Ming, because he had already noticed that the elder's face had become ugly.

Although Li Ming is a very impulsive person, she also understands that she is in the underground world now and can't mess around, so she keeps taking deep breaths and forcibly calms down.

Not to mention Liming, Jiang Hao's heart was also very moved, you must know that it was because of the outbreak of the last days that he lost his sister. However, Jiang Hao understood everyone's position, so he also began to persuade Li Ming: "Let's not get excited, let's listen to what the elders have to say first." ”

Jiang Hao then turned to the elder: "I'm sorry, we were a little excited just now, I hope you don't take it to heart." ”

The Elder's originally not very good face gradually improved, and he said, "Actually, I can't blame you, after all, your surface world has just experienced a crisis. For us, 220,000 years have passed since that crisis, and we are no longer able to understand your hearts and feelings. I apologize to you for my negligent words, but ......"

The elder turned to Li Ming and said to Li Ming very seriously, "Please understand one thing, the virus on the surface has nothing to do with us. Because the rocks of the underworld began to change 220,000 years ago when Judgment Day erupted, no tool could break the rocks. ”
