Once this formation is successfully set up, it can completely reverse the aura of a world.

Converting demonic energy into spiritual energy is indeed not a problem at all.

However, setting up the Heaven and Earth Yin-Yang Reversal Formation requires eighty-one top-grade Tongtian spiritual treasures as the foundation.

Seeing this, he couldn't help but frown slightly.

This requirement is a bit high.

Zhang Yuhe turned his head and asked Feng Xiaotian.

"Sect Leader, setting up the Heaven and Earth Yin-Yang Reversal Formation requires eighty-one top-grade Tongtian spiritual treasures. Does the sect have that many in reserve?"

Feng Xiaotian shook his head and said.

"No, top-grade Tongtian spiritual treasures are extremely precious, and the sect basically doesn't have many reserves."

"However, we obtained a large number of materials in the Demon God Palace this time."

"Refining eighty-one top-grade Tongtian spiritual treasures is not a problem at all."

Zhang Yuhe nodded.

The Demon God Palace has been passed down for millions of years, even longer than the Dao Saint Sect.

The various treasures accumulated in it are indeed exaggeratedly numerous.

Although most of these are items used by the demon race and are not suitable for cultivators.

But there are so many materials.

Using them to refine eighty-one top-grade Tongtian spiritual treasures is indeed not a problem.

There is even a lot left over.

It just requires a little more time.

"I'll do it, I'll refine these top-grade Tongtian spiritual treasures."

"Sect Leader, please inform the sect to let the Demon Suppression Army enter the Cangyun Realm as soon as possible."

Hearing this, Feng Xiaotian couldn't help but be a little surprised.

"Senior Brother, you can also refine artifacts?"

"I know a little."

Zhang Yuhe nodded.

"Alright, then I'll have to trouble Senior Brother."

After Feng Xiaotian finished speaking, he handed over a storage ring.

The ring was filled with various rare materials.

Setting up the Heaven and Earth Yin-Yang Reversal Formation is a major event for the entire Dao Saint Sect.

Naturally, Zhang Yuhe couldn't be allowed to contribute both effort and materials alone.

Zhang Yuhe took the ring and then said.

"Then I'll go get busy first, Sect Leader, please return to Yufan Heaven as soon as possible and gather the army."

After speaking, Zhang Yuhe rose into the air and quickly arrived at the artifact refining hall in the Demon God Palace.

Feng Xiaotian looked at Zhang Yuhe's departing figure.

He also flew up and quickly flew away.

The Cangyun Realm and the Yufan Heaven are separated.

Without establishing a cross-realm communication formation, he couldn't directly contact the elders in the sect.

If he wanted to gather manpower, he would have to return to Yufan Heaven through the passage first.

Fortunately, Zhang Yuhe had previously seized two teleportation formations.

He could directly go to the vicinity of the passage through the teleportation formation.

Otherwise, he would have to spend a lot of time flying to the vicinity of the passage.

...

Three years have passed.

Since destroying the Demon God Palace, Feng Xiaotian quickly returned to the Tianxing Sea through the passage.

He sent a message to Lu Mingfang, summoning billions of Demon Suppression Army soldiers to enter the Cangyun Realm.

Although there were still a large number of demons in Yufan Heaven that had not been wiped out.

However, those demons were completely rootless.

As long as more time was spent, they could be wiped out sooner or later.

But the Cangyun Realm was different.

This was a true demon realm, and the number of demons living in this realm exceeded hundreds of millions.

Even if Zhang Yuhe kept controlling three thousand incarnations to sweep across the world.

But he couldn't possibly kill all the demons in this realm by himself, right?

If they wanted to completely control the Cangyun Realm, they had to mobilize a large army to garrison it.

Under Feng Xiaotian's command, the Demon Suppression Army rushed to various key nodes in the Cangyun Realm.

They established city fortresses and re-arranged the teleportation formations to connect them.

Then, using the cities as bases, they slowly cleared out the indigenous demons in the Cangyun Realm.

After three years of hard work, the cultivators of Yufan Heaven had completely gained a foothold in the Cangyun Realm.

Although there were still a considerable number of surviving demons, they were completely unable to compete with the Demon Suppression Army.

They could only retreat into the wilderness and struggle to survive.

...

The summit of Cangyun Peak.

On the former site of the Demon God Palace, a huge formation platform stood on the top of the mountain.

The entire formation platform was extremely large, occupying an area of ​​tens of miles.

Zhang Yuhe and Feng Xiaotian stood on the formation platform.

The sky was still gray.

The entire world was filled with rich demonic energy.

But all of this was about to end soon.

Zhang Yuhe turned his head and said to Feng Xiaotian.

"Sect Leader, I'm going to start."

"Okay, I hope Senior Brother succeeds once."

After Feng Xiaotian finished speaking, he flew out of the formation platform.

Zhang Yuhe stood on the formation platform, holding a mysterious formation plate in his hand.

After three years of hard work, he had already refined the eighty-one top-grade Tongtian spiritual treasures.

These Tongtian spiritual treasures were buried in various places in the Cangyun Realm according to the requirements of the formation.

Now, as long as the formation is activated, the demonic energy of this world can be completely reversed into spiritual energy suitable for cultivators to survive.

As Zhang Yuhe kept pinching the magic formula.

A dazzling light rose from the formation platform into the sky.

The light quickly spread around, like the sunlight at dawn, dispelling and reversing the demonic energy that enveloped the Cangyun Realm.

Strands of spiritual energy began to slowly grow from the earth.

Seeing this situation, the Demon Suppression Army below the formation platform let out a earth-shattering roar.

With the existence of spiritual energy, they could stay in the Cangyun Realm for a long time in the future.

This world was truly under their control.

Zhang Yuhe stood on the formation platform.

Looking at the light shining in all directions, the originally gray sky began to brighten up.

Seeing this situation, he couldn't help but breathe a sigh of relief.

"It's finally done."

After reversing the demonic energy of the Cangyun Realm, there was nothing else for him to do here.

After spending three years.

Now he could finally cultivate in peace.

Feng Xiaotian flew onto the formation platform, and he said excitedly to Zhang Yuhe.

"Senior Brother, we succeeded."

"Yes."

Zhang Yuhe was also very happy.

From then on, the Dao Saint Sect would become a super existence spanning two realms.

With the resources of this realm.

He believed that the Dao Saint Sect would usher in greater glory.

In this way, he could rest assured when he ascended to the Immortal Realm in the future.

Thinking of this.
