As soon as the Demon Killing pierced into Ye Zhengfeng's body, the Demon Spirit instantly seeped out of the Demon Killing, flashing with pitch-black light, quickly eroding Ye Zhengfeng's whole body, and gradually eroding into Ye Zhengfeng's Mud Pill Palace.

As soon as he invaded the Mud Pill Palace, the demon spirit saw Ye Zhengfeng's soul sitting in the Mud Pill Palace.

Ye Zhengfeng also saw this void demon spirit, and saw that the appearance of the demon spirit was no different from that of normal humans, except that his eyes were completely black, and the appearance of the demon spirit was even very elegant, and the temperament on his body was like a peerless Confucian who had read poetry and books, and his dark eyes flashed with wisdom.

Ye Zhengfeng's soul opened his eyes, looked at the demon spirit lightly, without the slightest accident or madness, and said calmly: "You're here?"

Seeing this scene, the demon spirit frowned a little bit wrong, and asked, "You are not afraid at all? Do you think that with your current soul, even in your physical body, you still have the ability to resist me?!"

What made the demon spirit feel even more wrong was that Ye Zhengfeng's soul actually laughed heartily.

"Haha, since you've said so, what are you afraid of?!Come over and devour my soul, and then my body will be yours. Ye Zhengfeng replied with a weird smile on his face.

Ye Zhengfeng's words made the demon spirit suddenly feel a palpitation, and quickly checked Ye Zhengfeng's body and soul, but there was indeed only a feeling of weakness, and there was not the slightest strong power in it, which made the demon spirit's mind settle, thinking that it was just Ye Zhengfeng's delaying strategy.

"Hmph, don't play your unqualified scheming in front of me, no matter what, you only have one way to be swallowed and controlled by me today, and now I will send you to hell. But don't worry, I will leave a piece of your sanity, so that you can clearly look at the painful expressions of your relatives being tortured by me, hahaha!!" The demon spirit laughed hideously, but his temperament still maintained that kind of elegance, which looked extremely weird.

Hearing the words of the demon spirit, a cold light flashed in Ye Zhengfeng's eyes, and he glared at the demon spirit coldly, and replied: "Then it depends on whether your million-year-old monster can really fight me!!"

The demon spirit's brows furrowed again, and then his face changed instantly, because on the demon killing that was connected to his life, I saw that there had been a strange carving, and the colorful light on it flowed, and the light and dark streamers exuded a sense of vicissitudes and simplicity, gradually spreading towards the entire demon killing.

"It's... This is the Gu Tong Seal of the Upper Realm!!How can you, a Nether Realm native, have this kind of sealing ban?!" The demon spirit shouted in a panic, he and the Demon Killer's life were linked, and if the Demon Killer was sealed, he would naturally be affected, and even he could already feel the powerful sealing power brought by the Gu Yu Seal.

"Haha!!A weapon that can be compared to the Demon Clan's Earthquake Clan Artifact, if I hadn't been prepared, do you think I would just break in so recklessly?!" Ye Zhengfeng turned calm, stood up and looked at the Demon Spirit with a wild laugh.

"Impossible!!The Gu Dong Seal is complicated and cumbersome, it is impossible to form so many seals in an instant, and even quickly spread to the entire Demon Killing Gun!What did you do?!" The Demon Spirit roared furiously, and bursts of violent demonic qi erupted from its body, continuously pouring into the Demon Killing through Ye Zhengfeng's body, resisting the seal of the Gu Dong Seal.

"Do you think that I have spent these three days in vain? I have been tortured by you for nothing, am I stupid?!My weakness is caused by the formation of a complete Gu Tong Seal, if it weren't for this, I'm afraid I wouldn't be able to fool you, an old monster, right?!" Ye Zhengfeng said coldly as he looked at the struggling demon spirit.

"You're still lying to me!!I've been monitoring your situation all the time for the past three days, and you haven't formed a Gu Tong Seal under my nose at all! Even if you've been secretly condensing, but the moment Gu Tong Seal succeeds, that kind of fluctuation is not something that your current cultivation can cover up at all!!"

As he spoke, the demon spirit's body took two or three steps back one after another, and after bursting out with an even stronger demonic qi, he stood firm, as if there was a suction outside the Mud Pill Palace sucking him.

The role of the Gu Tong Seal has gradually been played, and he is inevitably sucked back into the Demon Killing at this time, whether it is the seal of the Gu Tong Seal, or whether he wants to resist the Gu Tong Seal, it must be completed in the Demon Killing, because he can only exert his strongest strength when he returns to the Demon Killing.

"Haha, of course I can't hide it from you, but what if the Gu Tong seal is on my body?!" Ye Zhengfeng replied with a smile.

The face of the demon spirit changed in an instant, this was indeed really unexpected, he couldn't imagine that it was indeed a crime of non-war, others didn't know what the Gu Yu seal was, but he knew it very well.

The ancient seal, is a demon power to create the sealing method, specifically to deal with their powerful, but unruly demon soldiers and created, can completely suppress the demon spirit in the demon soldiers, the seal holder can control the prohibition in the seal anytime and anywhere, punish the soldier spirit, value to the soldier spirit is willing to be fully loyal, the ancient seal will turn into a seal seed, engraved in the spirit of the soldier spirit, eternal life and never betrayal.

However, when the Gu Tong Seal was created, it had a very big flaw, and it had the characteristics of printing without return, and the seal must have a strong enough target to seal it, otherwise if the target's level and strength were a little weaker, not enough for the Gu Yu Seal to absorb enough energy, the seal would immediately feed back to the body of the sealer, and the seal holder would be completely sealed by the Gu Tong Seal, and would suffer from endless seals forever.

This defect made countless demon soldiers feel the existence of hope, and countless demon soldiers in the upper realm were once sealed by the Gu Dong Seal, protecting their energy to the death, and then letting the Gu Dong Seal devour its master, thus escaping the control of the soldier master.

The Demon Race had already given up this sealing technique countless years ago, and when Demon Dao Xuan controlled him, he also used another set of sealing techniques, but he didn't expect to taste this kind of seal in the hands of a Nether native.

"How dare you!!You madman!!" The demon spirit looked at Ye Zhengfeng angrily, Ye Zhengfeng could use this set of seals completely, he didn't believe that he didn't know how risky this set of seals was?!

And if he delayed a little longer in the end and didn't stab the demon stab on Ye Zhengfeng's body, the Gu Dong Seal would be launched on Ye Zhengfeng's body, and then Ye Zhengfeng would have to be sealed by the Gu Yu Seal, and this Nether Realm natives would be too crazy!!

"Hmph! In the face of a peerless demon soldier like you, if I hadn't worked so hard, I'm afraid I wouldn't even be able to see the shadow of the demon killer, right? Now it's up to you to see if you can hold on to your residual energy, go back to your body!!" Ye Zhengfeng snorted coldly and roared at the demon spirit!!

The demon spirit glared at Ye Zhengfeng coldly, and replied coldly: "You will lose, you will definitely lose in the end!!! My residual energy is not much, and it is estimated that it is just enough for Gu Yuyin to absorb, but with such little energy, it is easier for me to keep, and it must be you who will lose in the end!!"

After speaking, the demon spirit did not resist the suction anymore, and went back to the demon slayer with the suction force.
