Elegant valley, pleasant scenery, gray flowers, gray rivers, plain and excellent, but also have a different flavor.

"I didn't expect the underground world to have such a beautiful and elegant view. Yang Yi looked at the elegant valley in front of him and was very surprised, completely attracted by the unique beauty here.

"In fact, the underground world is also quite beautiful, but it has suffered from war for a long time, and many elegant and beautiful scenery have been tragically destroyed, which makes people regret. Shang Zhou sighed.

"It's no wonder that the war between the two clans will inevitably destroy it. Yang Yi also felt sorry for it.

Shang Zhou shook his head lightly and said, "It's not just the war between our two clans, the Netherworld clan is also in turmoil, often fighting among themselves, and only in the important matter of invading our Tianxing Continent will they temporarily put aside their grievances and unite with the outside world." ”

"It seems that the seniors know a lot about the secrets of the Netherworld, can you tell them about the juniors?" Yang Yi asked.

"Xiao Yi, you still have to concentrate on healing, and I'll tell you all the secrets of the Netherworld in the future. Shang Zhou worried.

"Senior, don't worry, my injuries are fine, and I have recovered a lot so far, so let's talk about it. Yang Yi said expectantly.

Shang Zhou looked at his expectant look, hesitated for a moment, and compromised: "Okay, then let's talk about it briefly for you." ”

"Thank you, senior!" Yang Yi thanked him, and listened carefully to Shang Zhou's secret of the Netherworld.

A few hours later, after Shang Zhou briefly told him what he knew about the secrets of the Netherworld, he left in a hurry and returned to the camp to preside over the overall situation, while Yang Yi gently closed his eyes at this time, and while quickly recovering from his injuries, everything Shang Zhou said repeatedly flashed in his mind.

The underground world was originally called the Netherworld, a parallel world, which was once part of the Tianxing Continent, but because of the war of the hundred clans that year, time and space were shattered, making the Netherworld independent and a world of its own. Due to the fact that the netherworld had just been formed at that time, time and space were unstable, and there were often turbulences in time and space, and there was no Holy Spirit.

With the loss of time, the netherworld gradually stabilized and became a world that can be inhabited by living beings, but it is different from the general world, it is gray, dark, there is no day or night, and there is no concept of time, the most unacceptable thing is that the attribute energy of heaven and earth contained here is very scarce, and it is full of strange netherworld power all year round, like a dead and silent place.

I don't know when, the Netherworld ushered in a powerful 'god', using his own clever means to transform the Netherworld, and over time, the Netherworld appeared rivers, mountains, and patches of gray grasslands and forests. It seems that this so-called 'god' thinks the world is too boring, and he doesn't know where you have brought in groups of Terrans and other creatures and so on. In this way, the Netherworld welcomed its first inhabitants.

Over time, all the surviving human races and creatures have evolved in order to be able to adapt to the environment here

。 Since all the creatures in the Netherworld have completely adapted to the environment here, their reproduction rate is getting faster and faster, among which the human race has the fastest reproduction rate, and after various explorations, they have found a cultivation method that can improve their strength. Over time, the Terrans dominated the Netherworld and called themselves Netherworld.

The development speed of the Netherworld is too fast, and the survival materials of the Netherworld are limited, in order to be able to grab more survival resources, the Netherworld has begun the most chaotic era. At that time, the netherworld was full of wars, and in order to survive, they killed their compatriots and seized resources.

This chaotic era lasted for several epochs, and the Netherworld was completely controlled by greed, and they did anything to have more resources.

It seems that the 'gods' who transformed the Netherworld back then were angered by the actions of the Netherworld, and they took a big shot and taught them a hard lesson. At that time, the Netherworld was almost wiped out, and if it weren't for a talented clansman who broke through the limit and defeated this so-called 'god', perhaps the Netherworld would have been wiped out long ago. And the people who defeated the 'gods' were worshipped as the gods of the Netherworld by the surviving Netherworld. Since then, the Netherworld has entered a period of recuperation.

Resources are limited, war will come, it seems that the Netherworld God is also aware of such a heavenly principle, and in desperation, he made a huge decision, that is, to let his four outstanding disciples divide the Netherworld into four regions, each of them to do their own thing, restrain the clansmen, and appropriately distribute survival resources. After the Nether God explained everything, he began to practice in retreat, not asking about the world.

At first, the four disciples restrained their clansmen according to the wishes of the Nether God and distributed as many survival resources as possible. But as time went by, there were more and more clansmen, and the survival resources became more and more urgent, coupled with the fact that the Nethergod was not out of the customs, his four disciples launched a war in order to be able to survive the clansmen in their area.

The end of the war was that both sides were defeated, and the clansmen of the four major regions were killed one after another. With the infinite increase in the number of war dead, the survival resources of the Netherworld are no longer urgent, but more abundant. As a result, the four disciples of the Netherworld stopped the war and began to recuperate again.

During the recuperation stage, the four disciples of the Nether God held high positions for a long time, and they successively developed a desire to dominate, gradually abandoning all the wishes left by the Nether God. And with the passage of time, the strength of the four people also grew rapidly, and gradually grew into the realm of the Netherworld God, so the four of them were called "gods" one after another.

In the later stage, three of the four disciples of the Nether God had completely ignored their master, and even thought that the Nether God had fallen and would no longer appear. So he named the area under his jurisdiction in the name of 'god', and formed an army to feed the war with war, wanting to become a separate clan, and in this way, the three major regions of seven killings, greedy wolves, and broken armies were born.

The last disciple of the Netherworld, who is still a little conscientious, is worried about the Netherworld, and deliberately named the area under his jurisdiction Netherworld.

To show respect for the god of the Netherworld, inherit the title of 'Netherworld'. And in order to be able to resist the engulfment of other regions, he can only cultivate an army to feed the war with war. In this way, the four major regions of the Netherworld were officially established.

As the strength of the four of them grew, they discovered many interesting things, and they seemed to be able to sense the existence of parallel worlds. So they found a way to enter the parallel world in their own area.

I don't know when, the God of Broken Army finally found a way to enter the parallel world and entered the Tianxing Continent. At this time, he realized how beautiful the Tianxing Continent was, and how rich the survival resources were. So he immediately returned to the Netherworld, forcibly opened a passage, and led a large army to attack the Tianxing Continent.

Due to the extremely strong strength of the Tianxing Continent at that time, it was impossible to win only by relying on the army of the Broken Military Region, as long as he turned to the three major regions of Seven Kills, Greedy Wolf, and Netherworld. When the three of them heard about it, they did not hesitate to send a large army to attack the Tianxing Continent at the same time, but they were finally driven back.

Since the strength of the human beings in the Tianxing Continent to enter the Netherworld will be severely suppressed, and the long-term stay will be eroded by the power of the Netherworld, they cannot completely annihilate the Netherworld, and can only send people to guard the entrance to the Netherworld.

After the defeat of the Netherworld, they can only recuperate in the Netherworld, but their survival resources will become urgent when the population increases. Although the four major regions often fight, consuming the population in the name of war and depleting their survival resources, they still can't resist the temptation of the Skywalking Continent.

As a result, the four supreme beings of the Netherworld temporarily put aside their grievances and began to discuss entering the Tianxing World again. In the end, the four of them unanimously agreed that they planned to enter the Tianxing World and take it down completely.

In order to ensure victory, the Broken Army God proposed to reopen the other two entrances as surprise soldiers to raid the Skywalker Continent. At first, this approach really worked well, causing heavy losses to the humans of the Skywalker Continent, but in the end, it still ended in failure.

After the war, in order to avoid the recurrence of the Netherworld in the future, the Netherworld rushed out of the Netherworld and destroyed their homeland. All the peerless powerhouses of the Tianxing Continent unanimously agreed to send elite troops in the Netherworld to be stationed in the Netherworld for a long time, to observe the situation of the Netherworld at all times, and to change people every once in a while.

Since the passage to the netherworld is underground, after a long time, the netherworld is called the underworld. And in order to make everyone in the Tianxing Continent gradually forget all the information about the Netherworld, so that the human race can survive and develop smoothly, the peerless powerhouses in the continent have deliberately eliminated all the information about the Netherworld.

In order to prevent someone from entering the netherworld by mistake through the passage, experts were specially arranged to be stationed at the three major entrances, and a large array was set up. On the one hand, it can resist the sudden attack of the Netherworld army, and on the other hand, it can prevent humans from straying into the Netherworld.

This is also why when the Chaos Territory suddenly appeared in a bottomless underground pit, Hua Honghao had to inform Yang Yi and the others that they chose to forget

This is exactly why.

The Netherworld knew that the strength in the Tianxing Continent was extremely strong, and it was not something that their Netherworld could resist for the time being. However, with the help of the particularity of the Netherworld, the Netherworld has tried to invade the Skywalker Continent many times in search of opportunities. As long as they have sufficient troops, they will launch an attack, and even if they can't take the Skywalker Continent, they can take this opportunity to consume the number of people in the clan and temporarily relieve the urgent situation of survival resources.

After several conquests, the Skywalker Continent gradually grasped the time period for the Netherworld to launch an attack, and it was generally an invasion every five thousand years or so. And after mastering this law, the Tianxing Continent is always able to make a counterattack, sending troops into the Netherworld in time, completely controlling the Netherworld in the Netherworld, and preventing it from stepping into the Tianxing Continent for half a step.

Over time, the ordinary people in the Tianxing Continent gradually forgot the existence of the Netherworld.
