It's just that Mu Chen didn't rush to kill all those guys at once, after all, it would take a lot of time to refine all the souls of those guys.

What's more, Mu Chen also needs another purpose, and that is the Demon Mask.

The Demon Mask had traveled to many worlds with him before, but as the plane he entered became more and more powerful, the Demon Mask could bring him less and less help.

Although the Black Shadow Soldier has been strengthened, for the fantasy plane of Breaking the Firmament, even if he summons more Black Shadow Soldiers, he can only deal with strong people such as Fighter and Fighter at most.

As for the Dou Ling or even the Dou King-level powerhouse, even if he summons more Black Shadow Soldiers, it is not enough to see.

Even the Dou Ling and Dou Wang level powerhouses, the black shadow soldiers are powerless, and the Dou Huang and Dou Zong above the Dou King, or even the Dou Zun powerhouse, don't even think about it, it is estimated that if the other party stomps his feet, the black shadow soldiers will all die.

But if Mu Chen wanted to give up the demon mask like this, of course he would be reluctant, after all, the demon mask could block his handsome face and prevent himself from revealing his identity, there were so many subordinates, such a good thing, how could he give it up?

It was precisely because of this that Mu Chen decided to strengthen the demon mask.

And Mu Chen, as a saint-level magician, is not much different from the ancient gods in Jackie Chan's adventures, not to mention that Mu Chen not only cultivates magic, but also cultivates martial arts and cultivation, and now cultivates fighting spirit, and these four realms are not bad at all.

It is not too difficult to strengthen the demon mask, and as for the materials for strengthening, Mu Chen has a lot of powerful souls in his hands, and it is not too simple to strengthen the demon mask.

Zhongzhou.

In a small valley, after Mu Chen put down the prohibition around him, he took out the demon mask directly from the system.

As soon as Mu Chen took out the demon mask, he felt a feeling of blood connection coming from the mask, although this feeling was not strong, but it was real.

This demon mask has accompanied Mu Chen for many years, and it has already had a little relationship with Mu Chen, and it is normal to have a feeling of a little blood.

"Then let me see what you'll be like next." Mu Chen muttered from his mouth.

In the next second, Mu Chen directly exerted the ability of the spirit commander and took out all the souls on his body.

These souls are very huge, there are thousands of them, Mu Chen devoured a lot of these souls before, but not all of them were devoured.

At this time, most of these souls are Dou Zong powerhouses, and the souls of Dou Huang powerhouses are also a little, and there are five Dou Zun level powerhouses, all of whom are the hall masters of those soul branch halls that Mu Chen exterminated before.

Although their souls were very powerful, they all surrendered in front of Mu Chen's ability to restrain the spirit generals.

If someone else were to perform the Soul Detention Dispatch, not to mention that these souls were detained, it would be good if they could not be killed.

Although they only have souls left, they are one of the powerhouses themselves, and even if they become soul bodies, they are also powerhouses at the level of the Dou Zong.

As for the original Dou Zong level, it was also a Dou Huang level powerhouse, and the Dou Huang level became a Dou King, and their strength had all dropped by a big order, but even so, their strength was very terrifying.

You must know that even if it is a Dou King, it is a strong person at the foundation building level, and the Dou Huang is a strong person in the Jindan Realm.

Mu Chen couldn't wait for a while at the thought of directly summoning the scene of hundreds of Jindan powerhouses, if the demon mask was successfully strengthened, this thing would become even more terrifying than the royal sword.

Subsequently, Mu Chen once again took out the Black Dragon Demon Crystal from the four-dimensional space bag, this thing has always been placed in the four-dimensional space bag by Mu Chen, and it can come in handy today.

In addition, Mu Chen also took out the Panku Treasure Box, if you want to strengthen the demon mask, you must need a huge amount of magic energy, so Mu Chen wants to borrow the energy of the Panku Treasure Box today.

As for how to convert the light magic energy in the Panku treasure box into dark magic energy, it was not too difficult for Mu Chen.

The difficulty is how to put these souls into the mask and engrave them all with the seal of the mask, only in this way can the mask control them, and they can be resurrected infinitely with the power of the mask.

And the energy of the mask also needs to be increased indefinitely, so Mu Chen plans to integrate the Panku Treasure Box with the Demon Mask, and let the Panku Treasure Box with almost endless power provide energy to the Demon Mask.

It's just that before the Panku treasure box is completely integrated into the mask, Mu Chen still needs to strengthen the demon mask, otherwise, with the powerful magic in the Panku treasure box, the mask is afraid that it will be destroyed directly, and this result is not what Mu Chen wants to see.

Then, Mu Chen's gaze fell on one of the soul balls of the many soul bodies on the side, this soul ball was not someone else's, it was Xiao Yan's.

I saw that Mu Chen waved his hand lightly, and directly transformed Xiao Yan's soul ball into Xiao Yan's appearance, and at this time, Xiao Yan's originally empty and expressionless eyes also began to become clear, and when Xiao Yan saw Mu Chen, his eyes were full of surprise and surprise.

"Teacher." Xiao Yan looked at Mu Chen in surprise and shouted.

"Hmm." Mu Chen looked at Xiao Yan with a happy face and nodded slightly.

"Master, am I not dead? Why am I now...," Xiao Yan looked at Mu Chen suspiciously, and said.

"You are indeed dead, I didn't expect that the people from the Soul Hall would appear in the Yunlan Sect that time." A flash of light flashed in the corner of Mu Chen's eyes and said.

"Someone from the Soul Palace?" Xiao Yan still had a puzzled face.

"Well, the strength of the Soul Hall in Zhongzhou is very strong, their hall master is a Dou Sheng-level powerhouse, and the elders of the Soul Hall are at least at the Dou Zun level, and there are not a few Dou Sheng-level powerhouses." Mu Chen replied.

After hearing Mu Chen's words, a flash of surprise flashed on Xiao Yan's illusory face.

"The people who killed you, the teacher has already killed them all for you, and I am also in Zhongzhou now, and the teacher came to Zhongzhou this time to destroy the soul hall." Mu Chen said.

"Master, what about my father?" Hearing that Mu Chen was now in Zhongzhou and had come to destroy the trouble of the Soul Palace, Xiao Yan was very moved.
