Just now they were still talking about when Zhang Chen's retreat would end and comprehend the power of the Great Dao.

As a result, before he finished speaking, he received a summons from Zhang Chen almost at the same time, and the content of the message was still exactly the same.

After being stunned for a moment, everyone reacted.

Wu Di, Blood Wuyan, Ning Hongyan, Lan Jia, Xiao Xu, and Zhang Lan stood up at the same time.

After glancing at each other, everyone's expressions were a little solemn.

The news of Zhang Chen's retreat, they learned from Xiao Xu and Zhang Lan.

However, they only knew that Zhang Chen was in the retreat of the Wuyuan Holy Sect to comprehend the power of the Great Dao.

But he didn't expect that Zhang Chen had already comprehended the power of the Great Dao and was beginning to construct the inner world.

Now the energy to construct the inner world is not enough, which is a bit difficult.

The construction of the inner world must be completed at one time, and if the energy supply is insufficient halfway, then it will not be possible to maximize the potential.

This is a huge disadvantage for future practice.

It is equivalent to having the strength to make a perfect score, but in the end he only handed in a 60-point answer sheet.

The key is that this answer sheet is still the answer sheet of the college entrance examination!

Wu Di glanced at everyone and said in a deep voice.

"Lan Jia, Xiao Sha, and the Blood Boundless Seniors, you first go back to the sect to prepare cultivation resources."

"Brother Zhang Chen is in my Wuyuan Holy Sect, I will return to the sect with Hongyan and Zhang Lan first, and provide him with the best source stones."

"After you prepare your cultivation resources, come to my Martial Source Holy Sect, so that you can be foolproof."

When the three of them heard this, they all nodded solemnly.

Without too much hesitation, he directly broke through the space and rushed to their respective sects.

When he was rushing back, he also sent a message to the Great Emperor Taishang Elder who stayed behind in the sect, asking them to start collecting cultivation resources first.

After Wu Di and Ning Hongyan glanced at each other, they also took Zhang Lan to Wuyuan Holy Sect.

They all knew that Zhang Chen had obtained the treasures of the three Heavenly Emperors who had been killed by him a year ago.

As a result, Zhang Chen told them that he had not enough energy to construct the world in his body.

It horrified them.

The treasures of two Awakening Stage Peak Heavenly Emperors and one Early Heavenly Emperor of the Apocalypse Stage, plus those cultivation resources that Zhang Chen had collected from the four major forces.

With so many cultivation resources, it can be enough for other Heavenly Emperor powerhouses to construct the inner world six or seven times, right?

Zhang Chen constructs the inner world alone, and this is not over yet, and he is already in a hurry.

How huge is the inner world he has constructed, and it is not enough to consume so many cultivation resources?

They only hoped now that Zhang Chen's cultivation resources could support them to return to the sect.

Wuyuan Holy Sect Secret World.

Hongmeng Cave Mansion.

Zhang Chen's expression was calm, and he was surrounded by a strong world power.

Above the dantian, a huge whirlpool of world power was constantly spinning.

Every time it rotates, a massive amount of world power will flow into the world inside the dantian, extending the scope of expansion.

Now Zhang Chen's body has reached an astonishing 11 billion miles.

You must know that the surface area of the Blue Star where it was located in the previous life was only 510 million square kilometers.

In other words, Zhang Chen's current body world area has exceeded that of Blue Star by ten times!

Before the construction of the inner world ended, the area of the inner world already had the sum of the surface area of the ten blue stars!

Although this area is equivalent to a thousand worlds, it can't even compare to a domain.

But there is one thing that needs to be paid special attention, Zhang Chen has not really broken through the Heavenly Emperor realm yet!

When Zhang Chen's internal world was over and he really broke through to the Heavenly Emperor, how huge should the internal world be at that time?

After all, the world that the ancient emperor powerhouse could create was only the middle thousand worlds.

It is worth mentioning that the further you go, the faster the extension and expansion of the inner world.

The treasures of the three Heavenly Emperors of the Tianyan Dao Sect are only the last tenths of them until now.

At most, there will be one more hour, and the energy of Zhang Chen's internal world will be terminated due to the exhaustion of the Heavenly Emperor's treasure.

"Boom!"

With a roar, the gate of the cave was opened, and Wu Di, Ning Hongyan and Zhang Lan, who looked anxious, appeared at the door of the cave.

Looking at Zhang Chen, who was still constructing the inner world in the cave, the three of them were all relieved.

Hurry up, hurry up, finally catch up.

It would be a great loss if the expansion of the inner world could not reach the maximum extent due to the lack of energy.

Wu Di raised his palm, and a steady stream of top-grade source stones and cultivation resources flew out of his palm.

I don't know if it is because of the supply of these top-grade source stones and cultivation resources, the extension and expansion speed of Zhang Chen's internal world has once again soared.

Time passed, and hours passed quickly.

The three of them rushed one after another to deliver cultivation resources to Zhang Chen.

When they came, Wu Di quietly wiped a cold sweat.

If these three came a little later, his Martial Source Holy Sect would be a little unable to support it.

The speed at which this consumes cultivation resources is too fast!

Millions of top-grade source stones, in just a moment's effort, the power of the world inside was completely absorbed.

Who would dare to believe this?

With the energy supply, Zhang Chen's progress in constructing the inner world has been advancing, and it has not stopped due to external forces.

Ten hours had passed again, and Zhang Chen no longer absorbed the power of the world in the top-grade source stones and cultivation resources.

Sensing this, Blood Wuya and the others glanced at each other, and they all smiled bitterly.

Thanks to them, they brought over most of the top-grade source stones in the Treasure Pavilion, otherwise it would really be a little insufficient.

took a deep breath and looked at Zhang Chen with some expectation.

The structure of the inner world is over, I don't know how vast Zhang Chen's inner world is?

After spending so many cultivation resources, no matter how much you have to spend more than a billion miles, right?

Maybe it can reach tens of billions of miles that they usually don't dare to imagine!

Zhang Chen seemed to be aware of it, and slowly opened his eyes.

Feeling the scope of the world in his body, Zhang Chen showed a heartfelt smile.

"Sure enough, comprehending the power of the Great Dao in advance is of great help to construct the inner world, thirty trillion miles, which is not bad."

When the words fell, Wu Di and the others were shocked, revealing a blank look.

How much did Zhang Chen just say?

Million...... 100 million miles?!

This range is beyond the realm of the Middle Thousand Worlds, right?!
