"I'm not too familiar with the materials of the Demon Emperor World. May I know which materials the demon lord has that you can't destroy?"

Gongye Mengyue had already reached the Great Emperor Realm, and her strength was first-rate in the entire Demon Emperor World.

She was stunned for a moment and had to think carefully.

"Master, please wait. I'll go and find out."

Saying that, she stood up and led her followers away.

The corners of Ye Changge's mouth curled up slightly.

This eastern region demon lord was constantly trying to rope him in.

He saw that she was straightforward and had the standard thinking of a craftsman. She also changed her style of doing things.

"She does have some tricks. As expected of one of the four great demon lords."

Gongye Mengyue disappeared for a long time and did not come back.

Ye Changge was not in a hurry.

The demon lords of the eastern region would definitely not be idle. They would test the items in their treasury one by one to see which of them could not be destroyed.

As they drank tea and repaired their bodies, it was soon evening.

"Thank you for waiting, master. After testing, I found these materials."

Gongye Mengyue once again appeared in the main hall and handed over a storage ring.

Ye Changge noticed that her entourage had changed.

After receiving the ring, Ye Changge began to carefully analyze it with his spiritual ability.

Inside the ring, there were actually hundreds of materials.

This made him sigh. The Demon Emperor World was blessed with abundant resources.

One had to know that back in the Heavenly Mortal World, after Ye Changge found out about the existence of Dao artifacts, he had already thought of ways to refine them.

In the end, he discovered that there were very few materials in the Heavenly Mortal World that were suitable for him to refine Dao artifacts.

If not for the fact that he still had the Hidden Kindness Cave Heaven, he might not even be able to carry out the refinement experiments.

"Demon lord, please use your demonic power to infuse into these materials here."

Ye Changge took out a few materials from the storage ring and handed them over.

Gongye Mengyue took a look and saw that there were a total of five materials.

There was a jade ring with a snow-white exterior and a black vapor flowing slowly inside.

There was a pale white skull with hollow eyes that seemed to be bottomless. She had only taken a glance earlier and felt that her body would be sucked in.

There were also two pieces of wood and a few pieces of unknown metal.

Gongye Mengyue did not ask further. She picked up the jade ring and activated her demonic power.

In an instant, a sacred majestic and an unpredictable aura enveloped the entire hall.

Whether it was the attendants serving in the hall or the guards guarding outside, everyone was shocked.

A pressure was pushing on their bodies, making it difficult for them to breathe.

"Could it be that the demon lord is trying her hand with that Mister something over there?"

The guests of the demon manor guessed one after another.

But none of them went over to investigate the situation.

After all, Gongye Mengyue's strength was acknowledged by everyone as powerful.

Ye Changge's expression was calm. No matter how powerful the demonic energy was in the hall, he remained motionless.

His divine senses were rapidly analyzing Gongye Mengyue's demonic energy.

"Enough, stop."

Gongye Mengyue would never have imagined that her demonic power attribute would be analyzed thoroughly by Ye Changge in such a short period of time.

As a divine level expert, Ye Changge had all sorts of abilities that the system had obtained from signing in. His divination ability had already reached a terrifying level.

Although the eastern region's demon lord had only displayed her demonic power very simply, it was enough for Ye Changge.

"This jade ring is suitable for you. It is a yin yang stone ring. The world was born with the yin yang attribute."

"These few pieces of metal are also suitable for you. They can strengthen the transmission of your demonic power and make it easier for you to use that artifact."

Ye Changge introduced the materials one by one.

When doing business with the other party, he was very serious.

After all, the returns he needed were not cheap.

"These can be used as the main materials of that artifact, but there are still some materials that are missing."

Ye Changge took out a jade slip and made a list.

"I'm not familiar with the materials of the Demon Emperor World. I've already recorded the characteristics of those materials in it. You, as the demon lord, can send people to follow the map to find the key."

"In addition, we still need some supplementary materials. This should be easy to find. You can get someone to take me to your material bank. I'll only know the specific materials after I've seen them."

Ye Changge's attitude was indifferent, but what he said was reasonable. Gongye Mengyue had no choice but to trust him.

She took the jade slip and at the same time, sent someone to call for Su Yueming.

"Yueming, lead the master to the material bank to search for materials."

Ye Changge did not waste any more words and left with Su Yueming.

...

While Ye Changge was in the eastern region's demon lord's mansion to look at the materials and complete the transaction to recover his strength...

The Demon Emperor World was in chaos.

The experts of the Spirit Jade Demon Guard went together to intercept the guests of the eastern region's demon lord's mansion. In the end, all four experts died.

According to the demon cultivators who ran over to investigate, it was certain that three great demons had all died at the hands of the same person.

Moreover, those three great demons had all died from the same sword technique, that killed them with one sword strike.

The entire world was shocked!

Bu Rufei, Duan Tongfang, and Wan Menguan.

These three names were all famous beings.

If they acted together, as long as it was not the four great demon lords acting personally, they would usually be able to achieve their goals.

They were actually killed with a single strike.

More and more factions sent people to investigate the situation.

Very quickly, a shocking piece of news spread throughout the Demon Emperor World.

Back then, the Spirit Jade Demon Guard had not sent three people to intercept them, but four people.

He was not listed in the list of troublemakers. This nameless expert, who was infamous among the experts, also died in that battle.

Countless demon cultivators began to investigate the news of Ye Changge.

The small town where he first appeared was turned upside down.

And more demon cultivators went to the Death Aura Forest to investigate the situation.

The Death Aura Forest, which had been quiet for a long time, became lively.

At the same time, because of Ye Changge's arrival, the reputation of the demon lord of the eastern region also rose further.

Almost all the demon cultivators of the Demon Emperor sector knew that the current situation was a four-sided struggle for hegemony, with the Spirit Jade Demon Guard and other forces stirring up trouble in the middle.

Now that a mysterious expert had joined, Gongye Mengyue received even more support.

Very soon, Ye Changge's identity as a refiner was also exposed.

The prestige of the eastern region's demon mansion soared, becoming the biggest subject of conversation.

Ye Changge did not care about any of this.

He was not from this world, and he did not have much interest in this place.

Other than signing-in, he was not willing to move around in this world.

And as his influence expanded, more and more people came to the eastern region's demon mansion to investigate.

People had already begun to approach Ye Changge.

In order to find the way back to the Heavenly Mortal World, Ye Changge needed to find information about the few worlds that he had visited before.

Whether it was the Luo Mountain World, the Mountain Martial World, or the Great Xia World.

"It's best if it's not the Great Xia World. With my current strength, I can't do whatever I want in that world. I'm just afraid of accidents happening."
