This is a red and blue world, and there is a person in the center of this world, who is constantly exhaling the aura of this world, and the aura on his body is constantly getting stronger over time.

Bronze, silver, gold,

The aura on Yang Yu's body was constantly getting stronger, and with a snap, Yang Yu was making a breakthrough and successfully returned to the platinum level.

But this is not over, in this red and blue world, the energy absorbed by Yang Yu is not even a quarter, if it can be absorbed all, it is not enough to reach the realm of eternal diamonds.

"Buzz!"

In Yang Yu's body, the world rune that he got from Ruiz's hand constantly emitted a soft light, resisting Yang Yu's refining of it.

Yes, refining.

In the Shennong Materia Medica, there is a method of refining the natal weapon, and Shennong Ding is refined through this method, and Yang Yu in the past has no way to do this world rune in his body, so he can only let him entrench in his body like an uncle.

Now that he had obtained the method of refining, Yang Yu decided to do something to it.

The other flame rune is gone, and only this world rune is left, it is conceivable that the mystery of this world rune, if it can be refined, the benefits that Yang Yu will get may be much greater than the improvement of the realm.

The red and blue energy was constantly absorbed by Yang Yu and transformed into the energy in his body, and at the dantian, Yang Yu had formed a quaint small tripod, and the mysterious world rune was in the center of the tripod.

The world rune that felt the crisis emitted a soft light, and wanted to break free, but this time it was imprisoned by Yang Yu.

"So, let's go!"

Yang Yu said a fool in his heart, this foolish speech is a signal, the simple little ding first appeared on the green representing vitality, and then this green turned red.

Flames rose from the small ding.

Wood makes a fire!

This is the combat method recorded in the Shennong Materia Medica, the general form is the wood form, but when you need to fight, this wood aura can generate fire attributes, which is also an important reason why the Shennong clan is respected as the Yan Emperor.

"Boom!"

At the dantian, the flame scorched the world rune, but it had no effect, and the soft light emitted by the world rune blocked the flame from the outside, which had no effect at all, and the refining became a joke.

"This thing is really not ordinary!"

Yang Yu muttered to himself, his heart moved, and a large amount of fiery red surged in, more precisely, on the small tripod of the dantian.

The intensification of the flames made the soft light emitted by the world runes a little unstable,

When Yang Yu saw this scene, his face showed a touch of joy, and it seemed that he could succeed.

He has come this way, this world rune has helped him a lot, if it weren't for this world rune, maybe Yang Yu would be gone a few times.

For a long time, this world rune has been ignored by Yang Yu, and Yang Yu's body has been used as a residence.

Now, the rent of this residence is going to be forcibly collected.

"Buzz!"

The world runes began to tremble, and this time the faint soft light could not shelter him, and the glory gradually became weak in front of the flames, twisting until it finally shattered on the spot.

Thundered!

The flames swept in, wrapping the world rune tightly in it.

"Success?"

Yang Yu's heart stared at this scene with some incredulity, is it really that simple?

It turned out that Yang Yu did think too much, the world runes wrapped in flames had nothing to do, and Yang Yu tried several times to plant his own mark but failed.

There is also a layer of super defense inside this world rune.

An hour,

Two hours

A day passed, and the world runes wrapped in flames were like a stubborn stone, and it was impossible for Yang Yu to grasp them.

"The last resort."

Yang Yu's mind took a deep look at Xiao Ding in the dantian, and Yang Yu, who was in the red and blue world, opened his eyes.

"Hah!"

A quaint small tripod spit out of Yang Yu's mouth and quietly suspended above Yang Yu's head.

"Burn!"

As soon as this word came out, the small tripod suspended above Yang Yu's head spun rapidly, and a large amount of red and blue energy turned into flames around this small tripod.

The color of the flame that encased the world rune in it gradually changed, turning into a red-blue flame, which looked very strange.

As the flames around it intensified, the fiery blue flame eventually became two colors, one pure blue and the other a golden yellow flame.

Yang Yu stared at these two flames quietly, for the golden flames, Yang Yu felt very clear in his heart, it was the power that belonged to Emperor Yan Shennong; And the other force is not difficult to guess, it is nothing more than the power of Fuxi or the manifestation of the power of the Yellow Emperor Xuanyuan.

Yang Yu quickly understood that the blue energy was the manifestation of the power of the Emperor Fu Xi, because the blue flame had turned into a flame gossip and was directly imprinted on the body of the world rune, wanting to give it a tattoo.

"Buzz!"

The world rune trembled, this time it was really feeling the danger, Yang Yu felt it, this world rune was struggling to resist this flame gossip.

"It's not enough! Again. ”

Yang Yu's heart was dripping blood, if this energy was used to absorb it, maybe it would allow him to break through to the realm of eternal diamonds in one fell swoop, but now it would all be wasted.

The blue energy is about to be exhausted, and only the fiery red energy remains, and under the control of Yang Yu, this fiery red energy is also covered in it, replenishing the energy for the flame gossip.

"It's now!"

The world rune was finally pulled out of a hole, and Yang Yu's mind, who had been waiting for a long time, directly entered the interior of the world rune and began to condense his mind imprint, as long as the heart mark was successfully imprinted in it, then Yang Yu would not lose money this time.

"Crackling!"

There is a thunderbolt inside the world rune, wanting to destroy Yang Yu's mind, but with Yang Yu there is also the flame, the flame pounced, although it is no match for the thunder, but it is also delaying Yang Yu's time.

Fast!

Faster!

Hurry up for me!

When the flames were lost, Yang Yu's mental imprint finally succeeded in condensing, and slowly imprinted on the body of this world rune.

With his mind pinning on this world rune, Yang Yu finally knew the true origin of this world rune,

This is Valoran's most important World Rune, named Chaos, or another name for him: the Void.
