Lao Liu was very straightforward and prepared to set off directly, Ye Xu said goodbye to Xiaoyu and Yunwa again, and prepared to start his own way home.

"Wait, Xiao Xu, take these military coins, you may use them when you get to Heaven Formation City." Xiaoyu took out the small bag and gave it to Ye Xu.

"Thank you, Sister Xiaoyu!" Ye Xu was not polite, he accepted the money, when he went out, he still needed to bring some money with him, he had grown food for a year, and there were thousands of military coins, but it was right to bring more.

"Boy, I, Ye Xu, remembered, if you want to go back to the Changfeng Continent, you need to find a formation mage to teleport back to you, the formation mage will not help for free, and I will also give you some military coins, I don't know if it is enough." Lao Li also gave Ye Xu a Bao Jun coin at this time.

Several old men and old ladies stuffed Ye Xu with red envelopes one after another, Ye Xu thanked a few again, and under Lao Liu's impatient urging, the two set off.

Lao Liu directly pulled Ye Xu and rushed straight into the sky, turning into a black line in the air and disappearing into the sky.

"Woo woo, when will my brother come back?" Yun Wa saw that Ye Xu was gone, and began to cry again, no one would take him to play in the future, Yun Wa was very sad.

Lao Liu's speed is very fast, Ye Xu didn't expect Lao Liu to be so powerful.

"Uncle Liu, thank you, if it weren't for you, I don't know when I would have to go back." Ye Xu said to Lao Liu gratefully.

"We usually don't point you to anything, it's all your own credit, we just gave you a few exercises, I didn't expect you to be so competitive, with your own efforts to directly enter the realm of divine soldiers, originally we didn't have such great hopes, I didn't expect you to be really unexpected." Lao Liu said lightly.

"Uncle Liu, what kind of body are you using? It's so fast! Ye Xu was carried and flew extremely fast.

"This is the body method of the Empty Hades Army, as long as you work hard to cultivate, you will soon be able to achieve this effect, a few of our old guys have been in the Air Hades Army all their lives, and the cultivation is the same set of the Air Hades Army, the exercises are basically given to you, it depends on your creation, as for the exercises at the level of the god general, I will give you when you come here again, and it can be regarded as giving you a reason to come back." Lao Liu stroked his beard and said.

"I'll definitely be back." Ye Xu didn't have too much reluctance to the Changfeng Continent, after all, he had crossed over, if the disciples of the Pingyang Sect were willing to go with him, he didn't have the slightest reluctance, and his connections were just that.

"Well, it's okay to come here, after all, your small world has no future, and in the end, Shouyuan will run out and die, at most fight with some other forces, or come here and fight with real foreign enemies, even if it is death, it makes some sense." Lao Liu seems to be very disdainful of other places.

"Are our enemies the Berserks?" Ye Xu probably understood what was going on in his heart.

Many novels have written such plots, the Terrans have natural enemies, and those enemies appear to destroy the Terrans, as for why they appear, they all involve the secrets of the universe, and the situation is obviously similar here, caring about some big worlds, the Terrans are fighting with the enemy, and the people in those small worlds don't know these things at all, or only some extremely powerful people are qualified to know these things, after all, it's useless for the weak to know.

"Is the Mad Blood still very powerful?" Ye Xu wanted to know about the situation.

"That's it, a garbage race, now the Air Hades Army has basically swept away the mad blood clan, they only have some bed bugs left to hide, and they can't make any waves, but our enemies are not only one mad blood clan, there are many more behind the mad blood clan, they also have a third-level world, and there are very many races in that world." Lao Liu said.

"Level 3 world?" Ye Xu didn't understand very well, no one had told him these things.

"Well, you haven't heard of that! I'll tell you a little bit, it's good that you know, after all, the more you know, the more desperate you are. Lao Liu began to explain to Ye Xu.

There is an extremely powerful existence, and all worlds are divided into levels, a total of nine levels, the highest level of the first level, and the lowest level of the ninth level.

The ninth level is the chaotic world, there are no living creatures here, the whole world is chaotic, it is the primitive state of the world, all kinds of substances are in the primitive state, there are no rules.

The eighth level is the initial world, which is the evolved version of the chaotic world, and there are certain rules here, but the overall is still disordered, and there are some creatures, which have not formed civilizations, and all rely on instinct to exist.

The seventh level is a low-level civilization world, races have appeared, and civilizations have begun to appear, but they are still very low-level, and the rules of the world are basically complete, and most of them exist in the form of tribes.

The sixth level is the ordinary cultivation world, the world rules are complete, the racial civilization has appeared systematically, the race is active, the national sect has appeared, the writing has been standardized, and the Changfeng Continent is at this level.

The fifth level is the high-level cultivation world, and the cultivation civilization has further become stronger, compared to the sixth level, it has undergone earth-shaking changes, and the strength of the race has become very strong, and it has begun to challenge the rules of the world.

The fourth level is the world of rules, which is regarded as a further development of the Xiuzhen civilization, and the races here have begun to control the power of rules, and the stars fall with a wave of their hands, the sun and the moon are gone, and the current boundary river is at this level, and among all the worlds, the number of fourth-level worlds is the largest.

The third level is the world of immortals, these worlds are very special, they are personal worlds, powerful cultivators have mastered the power of creation and begin to create their own world, in this world, this person is invincible.

The second level is the world of Shenfu, and Lao Liu doesn't know what it is.

The first level is the metaverse, this metaverse is said to be the beginning of the world, but also the end of the world, what it is, of course Lao Liu doesn't know.

After listening to Lao Liu's talk, Ye Xu thought about it, but didn't understand.

"Uncle, are these worlds a level of inclusion of a level? For example, does the third-level world include all the worlds behind the fourth-level and fifth-level worlds? Ye Xu wanted to ask if the world was getting bigger and bigger according to the level.

"No, there is a possibility of inclusion, but most of them are parallel, for example, like your Changfeng Continent, it is a sixth-level world, and the boundary river is a fourth-level, but the Changfeng Continent is not in the boundary river world, but another time and space, so it is necessary for the formation mage to pass you out, if it is in the boundary river, it will be simple, you can fly back by yourself." Lao Liu said.

"Oh! How did the mages know where our world was? Ye Xu couldn't figure it out, since it was a different time and space, how to position it.

"Hehe, as long as it's the world of the human race, we all have a position, it's given by those immortals, how do we know it, that's not something we can understand." Lao Liu continued.

"Each world is not fixed, but is constantly changing, and after many years, the ninth-level world may be upgraded to the eighth-level world. And the fourth-level world may also go through a big war and directly become a ninth-level world, the more powerful it is, the more destructive it is. Lao Liu said in a low voice.

"Huh? Is it so powerful? If those people are so powerful, then why don't they just take action and destroy the world of the hostile race. Ye Xu asked.

"Are you stupid? If it's so simple, then it's easy to do, the problem is that the other side also has powerful people, if it really fights like this, then there are only a few people left on both sides, so what's the point of their lives, they have to ensure the survival of their own race, not to die together. Lao Liu glared at Ye Xu.

"Uncle, is there a world that is not leisure?" Ye Xu wanted to ask, what kind of world is like the earth.

"Yes, some worlds are not developing cultivation, but other developments, I know that there are technological worlds, they don't study science and technology through cultivation, their individuals are very weak, but the things they study are very powerful." Lao Liu said.

"Oh, so what happened to them in the end?" Ye Xu asked hurriedly.

"In the end, I played myself to death, because they are very weak, although they have very powerful weapons, but as long as there is an accident, they may be exterminated, after all, no one dares to guarantee that there will be no accident." Lao Liu began to tell Ye Xu a few examples.

Some of the technological worlds have researched very powerful weapons, but unfortunately in the end, the race war, those weapons came directly to the same end.

In some worlds, technology has begun to improve the quality of the human body, which has led to problems with people's genes, and eventually the entire race has been destroyed.

There is also playing biotechnology and turning the whole world into a zombie world.

Anyway, because the individual is too weak, the ability to resist risks is too low, as long as there is an accident, it will be over.

But not all of them are unsuccessful, there are also successful, Lao Liu knows that a world still exists, they combine people and machines, although they do not cultivate immortals, but they solve the disadvantages of human weakness, and now they are also very powerful, they combine machines and people very perfectly, calling themselves the mechanical world.

"Oh, then Uncle Liu, have you ever heard of a world called Blue Star?" Ye Xu asked casually, he wanted to know if he could return to Blue Star.

"Blue Star? I haven't heard of it, it's useless for you to ask me, you have to ask the array mages, if they know, then they can teleport over, where did you know about this place? "Lao Liu has never heard of Blue Star.

"Oh, I remember reading it in a book before, so I just asked." Ye Xu was busy perfunctory.

"There are too many worlds, and the array mages may not all know about them, and there is also the fact that the boundary river is only one of the four levels, and the worlds that can be connected are limited, you can come here, which means that your world can be connected to here, many world boundary rivers can't go, if you want to find those worlds, you need to go to other worlds." Lao Liu said.

"The third-level world, have you ever been there, uncle?" Ye Xu asked curiously.

"No, if you go to Empty Sky City, where the Emperor of the Void Underworld is, you may go to the third-level world once, and the closest to us is the world of the Void Emperor, and the world of the Great Emperor is the third-level world." When Lao Liu mentioned the Emperor of the Void Immortal, he immediately showed a respectful look.

"Is the Emperor very powerful? Have you ever met the Great? Ye Xu looked at Lao Liu's appearance and knew that Lao Liu should worship the Emperor of the Void Immortal.

"What does it mean to be very powerful, the emperor is those who can make the world a ninth-level world, you say it is not powerful, I was fortunate to see the emperor, it was on the eve of a great war, the emperor inspected the air underworld army, and I saw the emperor's demeanor in the team at that time." Lao Liu showed a nostalgic look.

Ye Xu thought that Lao Liu was summoned by the Emperor, but he didn't expect that he just glanced at it from a distance, what is there to show off!
