"Is this...the fusion of heaven and earth?" Jiang Du couldn't help but widened his eyes and said after watching the whole process.

"Yes, it is the fusion of Heavenly Dao. According to our many calculations and arrangements, using different methods 1.5 billion times, we finally controlled the power consumed by Heavenly Dao fusion to within one hundred thousandth.

"Kong Yandao finally couldn't help but let out a long sigh of relief when he saw the two Tiandaos after fusion.

His expression showed extra excitement and extreme exhaustion.

One in 100,000...

Jiang Du listened to this number and couldn't help but stay there for a long time.

He has never really seen the fusion of heaven and earth.

However, he had truly experienced the devouring of Heaven's Dao, and how miserable it was to see the power of Heaven's Dao dissipate.

It can be said that two Heavenly Dao of the same scale, devouring each other, will consume at least 30% of the strength of the other side.

This is still in the case where one Heavenly Dao has no resistance. If it resists, this fusion can absorb 30% of the power of the other Heavenly Dao, which can be called a perfect fusion.

But now, the scholar and the senior have reduced this fusion of heaven and earth to one hundred thousandth.

Suddenly, the void shook slightly.

The power of chaos instantly erupted in the void, and the endless dark golden power, like a waterfall, continued to attack Kong Yandao and Xuexue.

The originally dark underground research room was completely transformed into a dark golden ocean at this moment.

Kong Yandao groaned, hurriedly sat down cross-legged, and began to practice quickly.

The scholar's face was much calmer. He looked at Jiang Du carefully and found out that Jiang Du was his student. He said to Jiang Du: "Absorb it. You are also responsible for this!"

Jiang Du showed an embarrassed look.

How embarrassing is this.

Then he sat cross-legged and absorbed this extremely pure power of chaos.

The system prompts sound continuously.

Jiang Du's strength began to improve in all aspects.

This is a gift from chaos, and it is truly extremely precious.

Jiang Du felt that everything about him was getting stronger, and the percentage numbers began to beat continuously.

Kong Yandao let out a muffled groan at this time, his breath jumped a lot, and he broke through to the realm of Tianzun.

However, this breakthrough is far from over, and Kong Yandao's aura is still increasing crazily.

All Jiang Du's strength reached a critical point.

Really, just a little bit away, you can break through to the legendary realm.

However, at this time, Jiang Du slowly opened his eyes, with a smile on his face.

More than half of the power of chaos in the underground research institute has been consumed.

And if Jiang Du breaks through at this time, it will be obvious that these energies are not enough.

Jiang Du also had a feeling. Whether he would make a breakthrough or not now depended on his thoughts.

Then it is better to leave these chaotic energies to the seniors and teachers.

The old scholar fell asleep directly at this time, lying on a recliner and snoring lightly.

Wisps of golden chaotic power continued to pour into his body.

Jiang Du didn't bother him. Now that he had met his seniors and teachers, although he didn't say a few words, this kind of breakthrough would not end in a short time. Jiang Du chose to leave directly.

But just after walking out of the tower of knowledge, the void shook again.

The dark golden waterfall strikes again.

Jiang Du looked at the golden waterfall pouring directly towards him, and the corner of his mouth couldn't help but twitch. Was it necessary for him to break through?

It should be his reward for discovering this secret.

Then Jiang Du refused, so he closed his eyes and started to break through.

"Ding, with the gift of the power of chaos, the heaven realm has reached the peak level of perfection. Do you want to start advancing?"

"yes!"

"Ding, I have received the gift of the power of chaos, and my heavenly consciousness has reached the peak level of perfection. Do you want to start the advancement?"

"yes!"

"Ding, with the gift of the power of chaos, the body of heaven has reached the peak level of perfection. Do you want to start advancing?"

"yes!"

"Advancing..."

"Ding, the origin of the positive and negative five elements has begun to advance!"

"Ding, the origin of space has begun to advance!"

"Ding, the nightmare origin has begun to advance!"

Countless system prompts sounded in Jiang Du's mind.

Jiang Du was immersed in the feeling of breakthrough.

Too fast.

His cultivation level advanced too quickly.

From the source realm, to the Tao realm, to the heaven realm, and now to the legendary realm.

How long did it take Jiang Du to complete the four realms?

It's completely unbelievable.

It was as if something was urging him to quickly improve his strength and do something next.

In Jiang Du's divine sea, a large golden bridge was originally formed, but it was still extending crazily.

There seems to be a way of never giving up until the end is reached.

However, the Divine Sea is too big. Even if this golden bridge extends very fast, it is still far from reaching the end.

What's even more frightening is that the Divine Sea is still breaking through the layers of fog and expanding.

When he broke through the legendary realm, Jiang Du absorbed a massive amount of chaotic power.

In addition, the remaining chaotic power was also absorbed by his energy.

His way of energy has undergone a completely new transformation.

The origin of the positive and negative five elements evolved into the source of the positive and negative five elements, and the origin of space evolved into the source of the space.

It's just that this space source seems to be unable to improve to a large level under the influence of the attachment badge, but stays at the level of perfection.

Countless people came out of the tower of knowledge and looked at Jiang Du sitting cross-legged in the void, their faces full of shock.

At this time, dark golden light was flowing around Jiang Du's body, and various strange phenomena continued to occur.

The Styx roared behind him, the gods were wailing between the Styx, metal, wood, water, fire and earth, wind, thunder, light, sound and darkness, all evolved into various strange phenomena.

The vacuum chants, the phoenix sings, the tiger roars, and the basalt roars.

"What kind of breakthrough is this? How can it be so terrifying?"

"Tianzun? No, Tianzun's breakthrough is far from reaching this point."

"Is it going to break through to the legendary realm?"

"It's bad. If we break through now, and it's such a grand breakthrough, it will definitely attract those taboos to take action."

"The person inside is Jiang Du!"

Because Jiang Du had done so many big things before and was related to the Tower of Knowledge, naturally some people would be able to recognize Jiang Du.

After all, Jiang Du had more than once led them into battle wearing a knowledge giant.

However, they were so worried that when Jiang Du made a breakthrough this time, everything was silent, and no one chose to take action against Jiang Du at all.

In the chaos, there are also streams of ideas communicating.

"It was actually the power given by Chaos that made the breakthrough. What is the relationship between this kid and Chaos?"

"It's strange. It's obvious that I have broken through to a legendary realm, so why do I feel so frightened?"

"Lao Xu, you want a wife... No, this is your favorite time to take action. How about you try the water first?"

"Do you think I'm stupid?"

"Um……"

"Grass!"

All in all, no one chose to take action against Jiang Du.

Whether it is the taboos on the human side, or other races living in chaos.
