When Mu Cheng moved, Dong Yinxie would immediately follow. It was as if he was stuck on him with ointment, unable to get rid of him.

This sort of situation caused Mu Cheng to feel like vomiting blood. This sort of fighting method was simply depressed to the extreme.

"I believe you should understand the so-called 'one power is enough to beat ten'. Now, I have to use my full strength. You must be careful."

Dong Yinxie leaned on the sword in his hand and rushed towards Mu Cheng. The moment the two touched in the air, a huge spark appeared.

The two of them retreated to the side. Dong Yinxie looked at the Sky Breaking Sword in his hand, where the light was dimmed.

However, Mu Cheng was in an even more sorry state. After this sword strike, Mu Cheng's hand was already injured.

Mu Cheng's entire right arm had been completely severed, and right now Mu Cheng could only use his left hand to fight the enemy.

Dong Yinxie glanced at Mu Cheng, then faintly said, "How is it, do you feel like your veins are broken?"

"Hmph. Don't be proud. This is only a superficial wound. Just look at yourself and you will know."

Mu Cheng looked at Dong Yinxie with disdain, then activated the healing abilities of the Mysterious Heaven Jade.

"Hmph, how dare you heal in front of me?" Dong Yinxie was very surprised, but in the next moment, his face changed color. It was a type of unspeakable pain, as though there was a turbulence within his body, as though all of his tendons were going to break. This kind of inhuman pain almost made Dong Yinxie faint from the pain.

"What did you do?" Dong Yinxie stabilized his injuries and looked fearfully at Mu Cheng. He clearly wasn't severely injured, but Dong Yinxie was almost crippled by the turbulence. It was really scary.

"Hehe, do you think my thousands of birds is so easy to resist? The turbulence will change the airflow around your body. "

"After that, it would enter your body. Although nothing happened at that time, it would lead to great harm later on."

Mu Cheng looked at the Dong Yinxie who was in extreme agony and casually said. This was also the reason why Mu Cheng dared to treat Dong Yinxie's injuries in front of his face.

"Haha, you are indeed powerful. I'm afraid that this Heaven Breaking Sword Technique is no match for you. In that case, you can only use your final trump card, the Immortal Vanquishing Sword."

Dong Yinxie laughed sinisterly, then let out a furious roar, as a terrifying killing intent burst out from his body and merged into Dong Yinxie's Sky Breaking Sword. The moment the two were compatible, it instantly created a huge wave that stirred the entire space.

Looking at the incoming sword projection, Mu Cheng called out her Thunder Sword to go forward to block, but upon contact, the Thunder Sword was penetrated by the sword projection. The entire sword projection pierced through, no, it was more accurate to say that it was a form of penetration that felt like it came from nothingness.

Mu Cheng was startled and immediately dashed forward. The sword shadow unexpectedly turned back and slashed at Mu Cheng as if it had already locked onto him.

"Is it over or not?" Mu Cheng was enraged as well. The sword shadow was like a piece of candy sticking to him, but it couldn't shatter it.

"Haha, this is Infinite Sect's Unparalleled Sword Intent. As long as you are in this space, you will not be able to escape. Prepare to die."

Dong Yinxie's face revealed a pleased smile, but in the next moment, he spat out a mouthful of blood. Mu Cheng happened to have caught sight of this scene, Mu Cheng instantly understood that this was the competition of endurance, it was obvious, Dong Yinxie was barely holding on to this gigantic sword projection, as long as Dong Yinxie was unable to hold on, the sword projection would disappear.

"Senior Brother, are you alright?"

Seeing Dong Yinxie spitting out a mouthful of blood, Wu Pu who was spectating at the side couldn't help but to worry, and could not help but to ask.

"It's fine, what's wrong with me? It's just my internal injuries from just now."

After Dong Yinxie said this, his face paled again, but his eyes continued to stare at Mu Cheng.

At this time, Dong Yinxie had already gone crazy, he wanted to kill Mu Cheng at all costs.

"Hmph, it is still unknown who will win, so don't be complacent Dong Yinxie, I can still hold on."

"I don't believe that with you controlling such a huge sword shadow, your mana will be depleted."

Mu Cheng coldly smiled as he dodged. At this time, even the most despicable method would be used to survive.

Mu Cheng looked at the slowly dimming sword image and heaved a sigh of relief in his heart. Then, he looked at Dong Yinxie who was on the ground, that fellow was still standing firm and upright, but his face was already extremely pale, and the blood had already stained his robes, making him look like a man made of blood that had just walked out of a pool of blood.

"Why aren't you giving up?" The flying sword in Mu Cheng's hand came to a halt, as he looked at Dong Yinxie indifferently.

He could feel that at this time, his opponent's sword projection already had no power to attack, so he stopped and looked at Dong Yinxie.

"Hehe, you are indeed very strong, worthy of being the person the Mysterious Heaven Jade chose. But no matter how strong you are, you will fall under my sword projection today."

Dong Yinxie's voice trembled. Although he was already spent, he still stared intently at Mu Cheng, as if he was not at a disadvantage at all.

"What's the point? Do you want us to both suffer?"

Mu Cheng retracted the sympathy on his face and stared at Dong Yinxie's stubborn face.

"Hmph, I still have another move that I haven't used yet." Dong Yinxie's body was already extremely exhausted, but he still persisted on.

Senior brother, are you going to use that move? If you do, you will sell your soul to hell.

Wu Pu looked at Dong Yinxie's back, and asked worriedly.

"So what if you're in hell? Isn't it still possible for you to become an immortal? Even if I enter hell today, I can still fight my way out of hell in the future." Dong Yinxie's cold face revealed a trace of a fanatical smile.

"What the hell is this guy trying to do?" Mu Cheng looked at Dong Yinxie with doubt in his eyes.

Dong Yinxie put his hands together, and stood there, the wounds on his body started to heal at a speed that could be seen by the naked eye, his entire being became extremely powerful, the dying Dong Yinxie had disappeared in an instant, and was replaced with a merciless, cruel, and cold-blooded Dong Yinxie who stood in front of Mu Cheng.

"Senior Brother, no, no!"

Wu Pu was shouting at the back, but Dong Yinxie acted as if he did not hear anything, and walked step by step towards hell.

The door to hell had already opened towards Dong Yinxie, and a terrifying aura swept over from the other side of the door.

Dong Yinxie's entire body was enveloped by that evil energy, and quickly merged into his body.

Mu Cheng looked at Dong Yinxie who was covered in black light and frowned.

This aura was extremely tyrannical, and now that Mu Cheng was standing in front of Dong Yinxie, he was like a child.

"Haha, what a wonderful feeling. It's been so long since I last devoured a human's soul."

"This wonderful feeling has been going on for too long, to the point that This King has forgotten."

An evil voice came out of Dong Yinxie's body. Mu Cheng looked at Dong Yinxie's expression and saw that he was clearly enduring immense pain. The feeling of having his soul forcefully devoured was not something an ordinary person could endure.

"I have already paid the price. Now, grant me your power." Dong Yinxie said with a trembling voice.

"Hee hee, since you are able to sell your spirit, you do not mind selling your body to me as well, right?"

"Because you no longer have any value left."

The Underworld Messenger laughed arrogantly, as if he was looking at a fool.

"Aren't you afraid of suffering a backlash from your inner demon if you don't keep your promise?"

Dong Yinxie let out an angry roar, and struggled to brandish the door of hell, but that door of hell was only an illusion. No matter how Dong Yinxie attacked, that door always existed, and wasn't affected by Dong Yinxie's attack at all.

"It's no use. Since you've already summoned me, don't expect me to be so kind, the Devouring Flame."

"I want to devour your body and achieve true freedom."

The Infernal Envoy finally bared his fangs, spitting out a huge mouthful of flames.

The flames were of the same nature as the flames of the Flaming Soul Beast, they were completely capable of burning one's soul.

Mu Cheng coldly watched Dong Yinxie's miserable ending, then closed his eyes and used all his strength to restore his magic power. If he let the hell envoy devour Dong Yinxie, then there would probably be a true battle going on and Mu Cheng himself wouldn't have any confidence in winning against this hell demon. Moreover, this hell envoy had already revealed his frightening strength.

After a while, a fangs like demon appeared on the ground. The demon opened its eyes, which were filled with destructive light, staring at Wu Pu behind him, revealing its sinister and terrifying fangs, it swallowed Wu Pu whole.
