In this way, with Mu Chen's help, it took Xiao Yan another three days to devour all the souls in the mask, and Xiao Yan himself broke through to the level of Douzun.

You must know that the number of demon soldiers in the mask can be said to be counted in millions, and it is normal for Xiao Yan to be raised to the level of Douzun in terms of combat power.

"Master, the apprentice has completed the master's task and devoured all the souls." Xiao Yan's voice sounded in Mu Chen's mind, this was the sound transmission trick that Mu Chen taught him.

"Well, then you prepare, I'm going to teleport the souls of these guys in, you get ready first, and when they all go in, you will suppress them all for me." Mu Chen said.

"Yes, master." Xiao Yan replied.

In the mask, Xiao Yan is no longer the appearance of the white young man he was at this moment, and Xiao Yan at this time has already incarnated into a Shura Killing God who exudes a bloody aura.

The monstrous black aura emanating from Xiao Yan's body made him look like a demon king who had escaped from hell, and his eyes were filled with blood-red murderous aura, which made people feel chilled.

At this moment, Xiao Yan's mind has changed greatly, but he still respects Mu Chen, which is exactly what Mu Chen wants to see, otherwise, Xiao Yan will not have the need to continue to stay.

At this time, on Xiao Yan's forehead, there was a strange silver-black symbol imprinted, this symbol was the seal of the demon mask, it could also be regarded as a contract, as long as the mask had enough strength, even if Xiao Yan died in battle outside, he could be resurrected in the mask again.

That's the scariest thing about the Demon Mask.

After hearing Xiao Yan's words, Mu Chen didn't hesitate, in order to upgrade this mask, Mu Chen had wasted several days, and he didn't want to continue wasting time.

Then, Mu Chen stretched out his hand and directly collected the thousands of soul balls, and those thousands of soul balls, under the control of an invisible force, flew towards the mask, and then directly submerged into the mask.

After the soul balls entered the mask, they all turned into their original appearance, and the originally cloudy eyes gradually regained their senses.

Between their foreheads, the same symbol as Xiao Yan also appeared, and after entering the mask, they were no longer free, and they were all marked with the same spell as the mask.

"What is this place?? Why am I here? ”

"Am I not dead? What is this place? ”

The space inside the demon mask is a blood-red space, not much different from the hell in Jackie Chan's adventures, but it doesn't have as many stones as in hell, this is a blood-red space.

And when everyone appeared inside the mask, they saw only Xiao Yan alone.

When they saw Xiao Yan, they were all stunned, they knew very well that they were dead, and now they had become a soul state, but why they appeared in this place, none of them knew.

And at this moment, they saw a person they didn't know, they were naturally stunned, and before they could speak, Xiao Yan took the lead and said:

"Hey, friends, welcome to hell, from today onwards, I'm your boss, and you're going to listen to me for everything, you know?"

Xiao Yan looked at the people who came in, his tone was full of recklessness and arrogance, and his miserable white face like a demon made it hard to believe that this guy was just a sixteen-year-old boy before.

"Boy, do you mean you're going to be our boss? I think there's something wrong with your brain. ”

"Hey, Qin Tian, why bother talking nonsense with this kid, when we come here, we must have nothing to do with him, let's take him down directly, and then ask if it's okay."

"yes, I think so too."

The five people who spoke were none other than the Douzun powerhouses of the several Soul Hall branches that had been killed by Mu Chen before, they were Qin Tian, Qinghai, Snow River, Prison Land, and Demon Rain.

The three of them, the Blood River, the Prison Land, and the Demon Rain are all Tianzun of the Tianzi-level Branch, and the three of them are unlucky, they happened to be sent out by the Soul Annihilation to carry out the mission, but they ran into Mu Chen halfway to find trouble.

The subsequent result must be conceivable, they were killed by Mu Chen without accident, and they became the ghost they are now.

As for Qin Tian and Qinghai, both of them were the hall masters of the Soul Palace's Disha Palace's branch halls, that is, the hall masters of the few branch halls that Mu Chen had approached, and they were all Douzun-level powerhouses.

Although Xiao Yan's appearance at the moment was very terrifying, but they were the Heavenly Venerable of the Soul Hall before, and none of their hands were stained with blood, just the fact that they looked terrible couldn't scare them at all.

"Then what are you waiting for, let's go straight on." After finishing speaking, the prison ground rushed directly towards Xiao Yan, and of course the other four people would not be left behind, and they also followed directly.

Xiao Yan saw the five people rushing towards him, and there was not the slightest fear on his face at all, some just sneered.

Just now he was thinking about what he was going to take, but now five guys are coming to the door, which is really good.

I saw a sneer flashing on Xiao Yan's face, and the soul power in his body was running wildly, and the black mist wrapped Xiao Yan's whole person in it, and rushed directly towards the five people who rushed up.

Bang bang bang!

The strength of the five of them has now become the Dou Zong level, where is Xiao Yan's opponent at the Douzun level? After just one move, the five of them were directly knocked out, and their bodies began to become illusory.

They are now in the state of soul bodies, not entities, although Xiao Yan's attack just now seems to be nothing, but from their increasingly thin bodies, it can still be seen that they are not as comfortable as they seem on the surface.

If it were an entity injury, each of these five people would have been seriously injured and had completely lost the strength to resist.

"Damn, this guy's strength is so strong, I was almost broken up by him."

"Me too, who is this kid and why is his strength so strong?!"

"Damn, I've never suffered such a big loss!"

Although these people were killed by Mu Chen, their arrogance as Venerable still exists, and Mu Chen is not there at this time, so they naturally have nothing to fear.

As for being subdued by Mu Chen, they naturally didn't know, after all, after Mu Chen used the Spirit Restraint to subdue them all, they directly lost consciousness.
