All the demon-eating fish were divided into several communities and gathered around the seventy-two islands. The Mirage Dragon Clan of the seventy-two islands provided them with enough food.

Of course, all food is not poured into the sea like garbage.

All food must be cleaned repeatedly to ensure it is clean before it can be put into specific sea areas and enjoyed by demon-eating fish.

Under Chu Xingyun's observation, with sufficient food supply, the survival and reproduction of the demon-eating fish were very smooth.

In just a hundred years, these hundreds of thousands of demon-eating fish have grown to more than 70 billion.

Outside each island, there are more than one billion demon-eating fish.

After developing to this scale, the Mirage Dragon Clan and the Demon-Devouring Fish Clan reached a balance.

The monsters consumed by the Mirage Dragon Clan every day, their scraps of materials can just feed more than 70 billion monster-eating fish.

For a hundred years, Chu Xingyun has not been idle...

While checking the reproduction of the demon-eating fish, he refines the innate material within the center of the earth by relying on the flames of the earth.

This innate material is the most advanced innate material taken from the Four Seas Dragon Palace.

These top innate materials are gradually accumulated by the Dragon Clan over the past billions of years, and have searched all over the ancient world.

Over the past billions of years, the dragon clan has been the supreme tribe of all races and the master of the universe.

The most top materials between the world are all in the hands of the dragon clan.

Although from now on to the infinitely long future, the demon race is the master of this world.

But there are only so many treasures, first served, those who come later will receive late, and those who don’t come will not be allowed.

At this point, between heaven and earth, 80% of the treasures of heaven and earth are concentrated in the hands of the dragon clan.

Even though the demon clan replaced the dragon clan, he became the new master of heaven and earth and the supreme of all races.

But what should be plundered has long been plundered by the dragon clan. Even if the demon clan plunders three feet of the ground, there are really no treasures to plunder.

Therefore, the dragon clan will always be rich and prosperous.

And the demon clan will never have much to do with wealth.

At this moment, in front of Chu Xingyun, 80% of all the innate materials born in the ancient world were placed in front of him...

In later generations, any of these more than 3,000 pieces of innate materials can be used to create an invincible treasure that is the most invincible to the world.

But now, there are more than 3,000 pieces of the same material.

Of course... At this moment, Chu Xingyun's seventy-two Earth Evil clones were harnessing the fire at the center of the earth and constantly melting it down.

The more than three thousand pieces of innate materials have completely melted.

Moreover, under the power of the earth's center of creation, all the innate materials have been completely fused and melted into a colorful metal melt.

Taking a long breath, Chu Xingyun thought and sacrificed the Seven-Star Ancient Sword.

Gululu...

Amid the sound of grunting, the colorful metal melt gathered towards the Seven-Star Ancient Sword.

Under the smelting of the seventy-two Earthly Evil clones, the colorful metal melt quickly merged into the Seven-Star Ancient Sword.

Looking at the sword body that instantly became thick and heavy, and was numerous times thicker, Chu Xingyun couldn't help but smile bitterly.

This is no longer a sword, but a big sword, or even a heavy sword!

Looking at the colorful heavy sword, Chu Xingyun couldn't help but sigh.

These innate materials are an ultimate manifestation in themselves and cannot be reduced through forging, refining and reducing their volume.

In other words, unless Chu Xingyun gave up some of the metal melt, the volume of this seven-star ancient sword could no longer be changed.

With a thought, Chu Xingyun knew that he had to make a choice, otherwise... his sword-controlling technique would be destroyed directly.

The heavy sword with such a huge size and such an exaggerated weight is extremely difficult to control.

Therefore, Chu Xingyun had to abandon part of the metal melt.

While thinking, Chu Xingyun poked out his right hand, and formed a sword technique with his two fingers in the middle, and instantly slashed at the ball of metal melt.

Chichi...

In a slight sound, the ball of metal melt should have divided into two balls.

Looking around, one of the balls quickly condensed into a three-foot long sword, and colorful light radiated all over his body.

The other group quickly condensed into a heavy sword, which was three feet long and radiated colorful light all over its body.

These two thin and thick swords, one of which is a flying sword used in conjunction with sword control.

The other one can only be held in hand and used in close proximity, which is a heavy sword.

Nodding with satisfaction, Chu Xingyun turned his head and looked at the seventy-two Earth Evil clones.

Looking around, Chu Xingyun said, "In the next 99810,000 years, you will do your best to help me refine these two swords, and don't be careless and distract yourself!"

Facing Chu Xingyun's words, the seventy-two Earth Evil clones nodded at the same time.

At this moment, these seventy-two Earth Evil clones share a soul with Chu Xingyun, so... they are very clear about the importance of two swords to Chu Xingyun, one small.

Chu Xingyun did not give any more advice. He knew that all the seventy-two Earth Evil clones knew, so there was no need to say more.

After the instructions were completed, Chu Xingyun withdrew from the core area of ​​the earth core.

After leaving the core area, Chu Xingyun turned around and waved his hands, laying out runes and magic circles.

After eighty-years of time, Chu Xingyun completely sealed the entire core of the earth.

So far, even if Chu Xingyun wants to open it, he will definitely not be able to open it.

Unless someone can destroy the entire core of the earth, there is absolutely no one who can enter the center of the earth and destroy the refining of these two swords.

Chu Xingyun firmly believes that once these two swords are refined, they will definitely become the most powerful supreme sword weapon from ancient times to the present!

Not to mention anything else, the more than 3,000 innate materials that gathered all the essence of the ancient world are destined to be supreme and have the identity and status of these two swords.

After sealing the earth's center world, Chu Xingyun nodded with satisfaction and turned around and left the earth core.

Next, Chu Xingyun has a lot to do.

In addition to the Demon-Devouring Fish Clan, there are also several large dragon-blooded half-demons, which are also like water and fire with the Demon Clan and will never be able to reconcile.

Not to mention... Chu Xingyun ran all the way to lobby and win over those dragon blood half-demon races that were irreconcilable with the demon race.

On the other side...

Inside the center of the earth...

As Chu Xingyun left, the seventy-two Earth Evil clones absorbed the firepower of the earth's center and constantly refined two swords.

As time goes by...

The two swords gradually changed...

in……

The negative innate substances are concentrated towards the heavy swords on the right.

The positive innate substances are quarreling with each other and the swords on the left are concentrated.

Gradually, the two swords turned into two completely different swords.

The white one is dazzling, and emits a thousand-foot light and a blazing temperature.

The black one is deep and exudes a gravitational force that swallows everything, as well as an extremely cold aura.

White light sword, black heavy sword...

Under the refining of the seventy-two Earthly Evil clones, the characteristics of the two swords are becoming more and more distinct and more opposite, and they are simply two extremes!

The opposition between light and darkness...

The opposition between yin and yang...

The opposition between heavy swords and light swords...

Of course, Chu Xingyun had no way of knowing all this.

After completely sealing the earth's core world, even the sensation between the soul has been cut off.
Chapter completed!
