Therefore, if the difficulty of opening up the first world is 1, then the difficulty of opening up the second world is 10000, which is still on the basis of the original world being able to carry the second world, otherwise the difficulty will be even more terrifying, and even reach the point where it is almost impossible.

It's like the cultivation of living beings is difficult in one step, and the same is true for opening up the world, and it will only be more terrifying, not simpler.

Even Ye Xiao was able to open up the 'First Realm', and there was no calamity, all of them were the effect of the supreme magic technique that condensed the Chaos Bead.

The reason why this is so is because the first realm opened up by Ye Yan is hung in the chaos, not above the flood wilderness, and a half-plane may have some impression of the flood wilderness, which will lead to calamity, but for chaos, it has no impact at all, and naturally it will not cause calamity.

So just now the idea of opening up a second world just appeared in Ye Yan's mind, and he was instantly annihilated, after all, this time the entire human race is opening up the world, and more than 120,000 worlds have already had some impact on the flood wilderness, and it is really not easy to open up the world, so as not to attract a terrifying catastrophe.

Although for Chaos, as long as it is not a world that has reached the level of the Flood Desolation, the burden will not be very large, even if there are many of them, after all, for the galaxy, no matter how many water droplets there are, there is no impact at all, but Ye Xiao chooses to accept it when he sees it, rather than being insatiable.

After all, whether it is him, or the entire human race, it is just an ant for the flood wilderness, let alone the unfathomable chaos, so sometimes being rational is definitely a very correct choice.

"The half-plane level world can only accommodate the Near-Immortal Realm, but once the world is transformed into a small world, then this world can accommodate the Golden Immortal Realm, the Taiyi Realm can be accommodated when it reaches the level of the world, and the Great World can accommodate the Daluo Realm. ”

"Although it takes nine calamities for this world to enter the world level from a small world in a short period of time, this world is not a flood after all, and its resources are limited, which is enough for the growth of the creatures in this world. ”

"And it's just that the realm of near immortals is still too weak for the flood wilderness, and it is better to wait until Zhong Ni and them reach the realm of the golden immortal consummation before letting them fly to the flood wilderness, and then not only will they have the power of self-preservation, but also increase the heritage of the human race. ”

Thinking of this, Ye Yan immediately made a decision, and in a thought, he turned into tens of millions, made some explanations with relatives and friends in this world, and then left the 'First Realm' and returned to the desolate world.

.....

Fengqi Valley, the tower of human cultivation.

"Buzz.."

With the flash of light, Ye Xiao's figure appeared for the first time in the Cultivation Tower, and reached out to put away the "Chaos Bead" floating in the air, no!

"Boom, boom..."

Looking at the brothers and sisters such as the Suiren who used the secret method to open up the world, Ye Yan glanced at it, did not disturb everyone, and focused his eyes on the white point of light floating in the air.

"It's. . . The thought of the immortals. Looking at the same thing as the idea that the ruthless man gave him at the beginning, Ye Xiao couldn't help but move slightly, stretched out his hand to touch the idea of the immortal in front of him, and in an instant, a large stream of information poured into his mind.

"I see. A sudden look flashed on Ye Yan's face, ignoring the thoughts of the immortals in front of him who were about to disappear because of the transmission of faith, and according to the information obtained, thousands of marks formed in his hands and hit the void in front of him.

"Hum..."

Along with Ye Yan's spell, the void in front of him began to distort, turning into an existence like a black hole.

"Whoosh. ”

Without hesitation, Ye Xiao flashed into the black hole in front of him, and after his figure disappeared, the black hole also disappeared as if it had lost its support, as if it had never appeared.

"Is this the zero layer of the Tower of Cultivation?" Stepping over the black hole, Ye Xiao's figure appeared in a void space, which was a special space without heaven, earth, and everything, and this was the zero layer of the Tower of Cultivation, which could also be said to be the non-existent tower layer.

It is also incorrect to say that it does not exist, after all, although this zero layer was opened up in the cultivation tower after the world was opened up, since it has been opened up, it still exists.

However, for Ye Yan and the other Terrans, this Zero Layer exists, but for other people, this Zero Layer does not exist, because this is a matter of great importance to the Terrans, and it will never be said to outsiders, let alone known by outsiders, so it is not an exaggeration to say that it does not exist.

After carefully understanding the zero layer located at the core of the Cultivation Tower, Ye Xiao couldn't help but nod with satisfaction, and said, "It's really a good idea, open up the zero layer at the core of this innate spirit treasure, so as to place the World Bead, so as to form a boundary sea composed of thousands of worlds." ”

"As long as this sea is not destroyed, the human race will not perish, and if you want to come to the zero layer of the cultivation tower, the prerequisite is to have the purest bloodline of the human race, as well as the specific magic recipe and the immortal thoughts of the owner of the cultivation tower, that is to say, too much consent. ”

"If there is no way to meet these prerequisites, even if you snatch the cultivation tower, it is useless, unless it is a complete cultivation tower, but unfortunately this cultivation tower is an innate spirit treasure, even a saint cannot be completely destroyed, so there is no place safer than here. ”

After sighing, Ye Xiao took out the "World Bead" carrying the 'First Realm', and sealed it into the void in front of him with both hands, completely hiding it.

After doing this, Ye Yan took one last look at the void in front of him, although he couldn't see it with the naked eye, he knew that there were beads carrying the world in the void around him, and with the passage of time, there would be more and more world beads here, until the day when he achieved the sea of the world.

Jiehai.. An ocean composed of "World Pearls", for this ocean, a "World Pearl" is a drop of water.

Ye Xiao left here with great relief, not only because of the previous reasons, but also because there was a secret hidden here that only he knew, even Youchao and others didn't know.

When opening up this place, Tai laid out the "Boundary Sea Great Array" here, which is a supreme formation that is even more terrifying than the Zhou Tian Xingchen Great Array and the Zhuxian Sword Array, because unlike the latter, which is based on the stars or the innate spirit treasure, this formation is based on the world.

The more world formations there are, the more powerful they are, and they don't need more, even if the "Boundary Sea Great Array" composed of more than 120,000 worlds created by the human race is enough to trap the Great Luo Jin Immortal, and when they reach here to completely achieve the boundary sea, even a saint and even a Dao Ancestor Hongjun can be refined.

This formation is too expensive, so the tens of billions of merits obtained by opening up the world were exchanged from the "Merit Heavenly List".

With this Realm Sea Great Array here, Ye Xiao and Tai Fang can rest assured that as for the so-called zero layer and the cultivation tower, they are just the first layer of protection.

As for whether this is too much, whether it is Ye Yan or Tai doesn't think so, because the boundary sea is the back road of the human race, and it is also the most powerful foundation of the human race, so it is impossible to be too careful.
