For immortal cultivators, the soul is the absolute foundation, and if the soul is damaged, it is like an incomplete avenue, and it is impossible to reach a profound realm if the avenue is not complete.

Therefore, if the problem of Situ Xuan's soul is not solved, it will be difficult for his cultivation to improve.

But the Demon Emperor Palace was a super force after all, and it was not that they hadn't come up with any way to solve Situ Xuan's soul problem.

They calculated that Situ Xuan released the power of his soul and used the thunder method to purify the soul entangled with his main soul, and he could not hurt his main soul.

The Demon Emperor Palace also invited a few powerful people who knew how to thunder to confirm this inference, but none of these powerful people could purify the soul that was entwined with Situ Xuan.

At most, they can only injure or completely destroy this soul, but it is useless, after this soul is injured, he can still recover with the power of Situ Xuan's main soul. And if you choose to destroy it completely, it will hurt Situ Xuan's main soul.

The reason why these powerful people couldn't purify Situ Xuan's soul power was very simple, that is, their thunder method was not advanced enough and they didn't have divine might.

But all thunder methods have terrifying destructive powers, but if you want to purify the soul, not all thunder methods can do it.

Only those high-level exercises can make the thunder method contain divine power and have the power to purify the soul.

Today, Situ Xuan's thunder method that led Su Mu to split Zhou Qin actually allowed his soul to be purified! The soul that entangled his main soul was purified as the evil cult that occupied the magpie's nest.

This was something that Situ Xuan didn't expect, and the old man with a full face didn't think of it.

They didn't expect that Su Mu's Thunder Law actually contained divine power that could purify the soul!

The soul problem was solved, and Situ Xuan laughed uncontrollably! Although he had suffered a lot of sword wounds, he still couldn't control the ecstasy in his heart!

He chose to completely fuse his soul immediately, he knew that his old grandfather would protect him, so he was not worried at all that someone could hurt him when he fused his soul, after all, his old grandfather was a powerful existence of the Three Calamity Immortals.

Su Mu and Zhou Qin joined forces, and the combination of Lei Fa and sword moves simply doubled the power, but even so, the two still couldn't break through the black protective shield.

"Knock"

"Knock Knock"

"Knock"

"Knock Knock"

A very slight, but very clear sound came from the black cover.

This voice was not only heard by Su Mu and Zhou Qin, but also by the people around them, it stands to reason that such a subtle sound could not have spread so far, but it made everyone present hear it clearly.

It's like a voice coming from the depths of everyone's heart, yes, it's the sound of a heartbeat.

"Knock Knock"

"Knock Knock"

"Senior Sister Zhou, this feels very bad, if you still have a trick, you can use it, if you don't use it, I'm afraid you won't have a chance!" Su Mu's eyes flashed with thunder, and his whole body was entangled with countless violent thunders, and occasionally he could hear the sound of air exploding inspired by the thunder power of his whole body.

"Senior Brother Su, I have a spell for a while, and before he comes out, we will join forces to set up a formation and trap him. Zhou Qin had already used all the powerful moves, and the only means she had left at the moment was the formation she had learned from ancient books.

This set of formations is called "Qiankun Dou Zhuan Demon Array", it requires two people to set up a formation, after the formation of the formation, the strength of two people can be gathered together to form a trapped formation with yin and yang reversed, unless the trapped person's cultivation is more than three times that of the person who arranged the formation, otherwise he can't break this formation.

Zhou Qin explained the method of arranging the formation, and then the two immediately began to arrange the formation.

Zhou Qin used his sword to carve a formation map around the black protective cover, and then injected power into it with Su Mu.

Just as this Qiankun Dou Turning Demon Formation was formed, a crack broke at the top of the black protective cover, and then a pair of black horns poked out from it, and then a young man's head slowly rose from the black gap, followed by his entire body.

"What is this!" Su Mu looked at the monster in front of him, which looked like a man but not a beast, and goosebumps all over his body.

"Senior Brother Su, don't be distracted! Although there is a formation that temporarily traps him, we still have to find a way to win against him. Zhou Qin knew that the next Situ Xuan she was going to face would be very terrifying, because she felt a very powerful momentum on Situ Xuan.

Situ Xuan, who had a strange shape, slowly opened his eyes, and his pupils turned out to be vertical pupils!

"The feeling of the five consummations of the first layer of the Supreme Demon Sutra is really wonderful! To thank you, I have decided to end this battle with the strongest move!" Situ Xuan's appearance has changed, and even his voice has changed, the cold voice from before is no longer there, but has become a blood-devouring and angry voice.

As soon as Situ Xuan finished speaking, the pair of horns above his head began to slowly shrink until they were completely withdrawn into his body.

Immediately, Situ Xuan glanced down at the mysterious pattern under his feet and said, "How can a mere formation trap me! The fifth layer of the Supreme Demon Sutra! Demon Lord Heaven and Earth!"

Situ Xuan's whole body was full of black qi, and he clenched his right hand into a fist and smashed it the wall of the Qiankun Fighting Demon Array!

"Knock"

The wall of the Qiankun Fighting Demon Formation was under Situ Xuan's punch, stirring up layers of ripples.

Seeing that his punch didn't blast through the formation wall, Situ Xuan instantly blasted out seven consecutive punches.

But the result was still the same, the wall of the Qiankun Fighting Demon Formation was still intact.

"Senior Sister Zhou, it seems that he won't be able to break this formation for a while, I have an idea, I don't know if Senior Sister Zhou dares to take a gamble!" Su Mu understood that ordinary means might not be able to win against the current Situ Xuan, so he decided to take a gamble!

"Senior Brother Su, there is no better way now, everything is up to you!" Zhou Qin chose to believe in Su Mu, and she could only believe in Su Mu, because she had no better way.

Su Mu's method was very simple, he found that his exercises and Zhou Qin's exercises could be perfectly integrated through his cooperation with Zhou Qin, so he had a bold idea in this situation.

He wants to cast a spell with Zhou Qin and perform a combined attack. He planned to use the Sea of Thunder himself, and then let Zhou Qin use the sword to transform into thousands of thousands, so that Zhou Qin could use the Thunder Sword to attack Situ Xuan.

This method of combining attacks can be described as a bold idea, not to mention whether it can succeed or not, this kind of whimsical idea alone is enough to show Su Mu's extraordinary.

After Zhou Qin listened to Su Mu's conception of the method of joint attack, she admired this senior brother of the Guizhen Sect even more in her heart, and she couldn't help but think, could it be that the Guizhen Sect was such a rebellious monster? In the past, there was a kind of anti-heaven monster that Wang Du used the realm of a six-rank immortal master to take a blow from the eighth-grade ancestor, and now there is a peerless talent like Su Mu!
