When the Demon Emperor used the afterimage to attack Mu Yun, he appeared directly behind Mu Yun, and slapped Mu Yun behind with a palm, knocking Mu Yun away directly.

Mu Yun felt that his back was hit by a mountain, and he felt a sharp pain all over his body, especially the spine on his back seemed to be broken, and the magic power in his body could not be activated freely. He said with a shocked tone in his eyes, "Your magic should not be able to attack me, how did you do it."

"Magic ineffectiveness is indeed a very powerful ability, but any magic is not impeccable. If I guess correctly, magic ineffectiveness is just a magic protection cover to protect you. All the magic that attacks you will be absorbed or decomposed by this protective cover. On the contrary, physical attacks can hurt you. That means you are not able to absorb all attacks, so I only need to gather the magic power in my body in the palm of my palm and explode directly. The magic at that moment is impossible to invalidate, so my attack will work." The Demon King said slowly.

"In just such a short time, you can actually see through the weakness of magic ineffectiveness. You are such a terrible opponent." Mu Yun said seriously, his face slightly ugly. After all, magic ineffectiveness is his greatest reliance. Now that this ability is invalid, if you want to compete with the Demon Emperor, you will be in a state of lifelessness.

"If you can truly cultivate to the realm of the True God and then use magic to become invalid, I may not be able to defeat you easily, but you are still one step behind you." The Demon Emperor said lightly, and his body suddenly took a step towards Mu Yun, and suddenly appeared in front of Mu Yun. His right hand hit Mu Yun's chest like thunder, knocking Mu Yun away directly.

Mu Yun opened his mouth and spitted out a mouthful of blood. When he looked at the Demon Emperor again, he saw that the Demon Emperor's bloody eyes were staring at him. Suddenly, his surroundings turned blood red, as if they were in a blood-colored world, and everything outside was isolated from him.

"Where is this place?" Mu Yun kept looking around, his tone was filled with shock.

"This is the illusion I created, a real and illusory existence. I didn't want to kill you, but I just hope you don't become enemies with me anymore." The figure of the Demon Emperor slowly appeared in front of Mu Yun.

"Your face." Mu Yun looked at the Demon Emperor's face, his tone was full of shock, because this was exactly the same as Xingyan, and even some subtleties were exactly the same, but his expression was a little cold, and he seemed to have no indifference to the eyes of any creature.

"This time is the last time. If there is another time, you will definitely become a corpse." After the Demon Emperor finished speaking, his face was directly covered by black fog. When the black fog dissipated, his appearance turned into what he was not long ago.

When Mu Yun saw the Demon Emperor, the red around him suddenly gradually dissipated, and the sound of fighting sounded again around him. He only felt a sharp pain in his left hand, and subconsciously looked at his left hand, and saw that the black bone sword held by his left hand had disappeared, and it was obviously taken away by someone.

The Demon Emperor held the black bone sword in his hand and said to Qiongqi, "We should leave."

Qiongqi seemed to be not happy, and let out a roar, but he still did not dare to violate the orders of the Demon Emperor, and returned directly to the feet of the Demon Emperor, spread his wings and flew towards the distance.

Under the protection of the four divine beasts, Ming Ji followed the Demon Emperor and left together. The gods around him did not dare to stop him at all. After all, Mu Yun was not the opponent of the Demon Emperor, and he and others were even more unlikely to be the opponent of the Demon Emperor.

Mu Yun stood there and watched the Demon Emperor leave, unable to move a little bit. Until the Demon Emperor disappeared, he could slowly move his body. The scene just now was full of doubts. Who is the Demon Emperor? Why did he look exactly the same as Xingyan? And he could kill himself just now, but he did not hurt him a little bit. Instead, he just took away the Bone Sword as the key.

"You all go back. The key here has been taken away. It doesn't make sense for you to keep it here anymore." Mu Yun said with a sigh.

The gods around them also flew towards Tiannuo City very lonely. After this battle, their self-confidence was directly hit hard. Originally, they thought it was very easy to just stop the Three Emperors and One from opening the Gate of Underworld this time, but the appearance of the Demon Emperor made them feel their insignificance, especially after the Gate of Underworld was opened, do they still have a chance of winning this time?

About half an hour later, Xingyan and Mu Xue appeared slowly. When they saw the scene of the mountain where the sealing key was broken, they hurriedly landed on the ground. Mu Yun sat quietly on a stone, gasping heavily, and sweating all over.

Mu Yun looked at Xingyan and Mu Xue who suddenly appeared and said extremely tiredly, "You are here."

"Has the key been taken away?" Xing Yan said with a sigh. It was obvious that he had guessed it long ago. After all, the strength of the Demon Emperor was so powerful that he knew very well. At that time, when Aotian had no evil demon power, he could not kill Aotian by occupying the body of the Demon Emperor with all his strength. Not to mention that the body of the Demon Emperor was now taken away by the Demon Emperor. The Demon Emperor had all the power of the Demon Emperor. Coupled with the super power of the Demon Emperor, his strength was simply unimaginable.

"Well, he is too strong." Mu Yun's body aged quickly at this moment. He aged to the appearance of a hundred-year-old man in a few breaths. Mo Li also flew out of his body. It was obvious that Mu Yun had been relying on Mo Li's strength to maintain his appearance just now.

Xingyan could see at a glance that Mu Yun's vitality had almost been exhausted. If he let it go, Mu Yun would definitely die without a cup of tea. So he immediately used the magic power in his body and directly enveloped Mu Yun.

At this moment, Xingyan discovered that Mu Yun's body was extremely injured, especially the muscles and veins were broken, the spine was completely broken, and the original power was almost completely dried up. Such injuries were no longer a simple repair magic that could be cured, so Xingyan immediately picked up Mu Yun and flew towards the Elf Forest. If he wanted Mu Yun to resurrect his vitality, he could only rely on the power of the Elf Queen.

Along the way, Mu Yun wanted to stop Xingyan several times, but he was extremely weak and no longer had the strength to say a word. He could only wait quietly for the arrival of death in a semi-dead state.

Xingyan was not idle along the way, constantly converting magic power into vitality and injecting it into Mu Yun's body, so that Mu Yun would continue the signs of his life that was about to disappear. If this trace of life also dissipated, then Mu Yun would probably never have the power to return to the sky again.
