978 Striking Down Yin Devil Sovereign

Li Yunmu continued sitting and studying Heavenly Emperor Ryukyu's notes. One month passed like that.

During this time, the system told him that if he used the experience points, the notes could be directly imprinted in Li Yunmu's brain, but he rejected this proposal.

After all, he wasn't only studying the notes but also experiencing Heavenly Emperor Ryukyu's difficulties and experiences.

Three more months passed before Li Yunmu closed the notebook and carefully packed it inside the heavenly world. It was the final object left behind by Heavenly Emperor Ryukyu, and Li Yunmu was extremely cautious so as not to ruin it.

Once finished, he stood up and quickly searched for the teleport portal in the void. Heavenly Emperor Ryukyu had already explained how to use it, and Li Yunmu soon disappeared.

When he reappeared in the ryukyu palace hall, he looked at the large hall. The corpses of the space-time spirits had already dried up with the flow of time as their blood entered the spirit refining formation.

Li Yunmu was standing in the hall while constantly shaking his head. His goal right then was the remnant soul of the Yin Devil Sovereign hidden in the ryukyu spirit hall.

"Since master couldn't deal with you, then allow me, his disciple, to strike you down!"Li Yunmu mumbled.

Li Yunmu quickly found the place where Yin Devil Sovereign was hidden. The remnant of his soul was staying at the top of ryukyu palace hall.

The entire ryukyu palace hall had been transformed into a large spell formation by Yin Devil Sovereign, and the summit was its core. Yin Devil Sovereign was sitting there, absorbing the souls of young talents he killed.

When Li Yunmu saw the Yin Devil Sovereign's remnant soul, he was gobsmacked, because in front of him, there was only a meatball. It looked extremely sinister and had countless veins and arteries, which were continuously throbbing, present on its surface.

The meatball seemed to sense Li Yunmu's presence. It released an enormous pressure to suppress him, but Li Yunmu had been taught by Heavenly Emperor Ryukyu, so this little bit of pressure couldn't do anything to him.

Li Yunmu only jolted slightly, and the pressure of Yin Devil Emperor was shattered.

"Jie jie, I haven't seen such a formidable soul in a very long time. Youngster, have you come to become my nourishment?" the meatball said in an extremely sinister voice and a vicious smile. Its appearance suggested that he wanted to gobble up Li Yunmu.

"I have come to destroy you!"

Li Yunmu looked at the meatball and recalled the matter of Yin Devil Sovereign trying to possess Heavenly Emperor Ryukyu's body. It instantly infuriated him.

"Hahaha, you are very interesting, youngster. Do you know who I am?"

The meatball didn't feel that Li Yunmu was very powerful. In his eyes, he was only a slightly more formidable great principal golden immortal.

But he didn't know that it was only because Li Yunmu's realm hadn't advanced. His combat strength at that moment could already be considered as somewhat more formidable than that of heavenly emperors.

Yin Devil Sovereign's remnant soul was equivalent to a half step emperor, sp he felt that Li Yunmu was only a minor character whom he could casually pinch to death, so he continued to sneer.

"A trifling remnant soul also dares to be arrogant in front of me? Truly reckless!"

Li Yunmu coldly smiled. He was unable to control his emotions. When he thought about the injury given by the Yin Devil Emperor which had resulted in his master's death, Li Yunmu's fury rose to the next level.

He had no wish to continue talking rubbish and summoned the Solitary Ignition Sword with his thought. He mumbled an incantation, once the sword's energy appeared, and a sea of fire appeared instantly above them. It went straight toward Yin Devil Emperor.

"A lowly insect. Eh? What kind of flame is this? Youngster, what are you doing!"

Yin Devil Sovereign saw Li Yunmu attack, but he still couldn't sense his strength. After all, for the past countless years, the immortal realm had been the ceiling of cultivation in the small world. No emperor level powerhouse had never entered it.

Because of that, he didn't pay much attention to what was being done and even used his body to resist Li Yunmu's attack. But what left him surprised was that Li Yunmu's attack was extremely formidable.

With just one attack, the Yin Devil Emperor's soul, which had recovered somewhat, was injured again. Moreover, the injury this time was more severe compared to the past.

Li Yunmu coldly smiled, not intending to give Yin Devil Sovereign any chance. The Solitary Ignition Sword was covered in flames, and one after another, sword energy slashes struck Yin Devil Sovereign's body. His injuries turned heavy in no time.

"This type of attack, you are an emperor realm powerhouse! NO! That can't be! But your presence indicates that you are only an immortal, so how can your attacks be so powerful?!" Yin Devil Sovereign roared.

At that moment, he could finally sense the strength behind Li Yunmu's attack. Panic filled him, since he had never expected that an emperor would surprisingly appear in the small world.

There had been a half-emperor called Yin Emperor, but he had never been able to sense Yin Devil Sovereign's existence. Moreover, he could not enter Yin Imperial Palace.

Yin Devil Sovereign was extremely confused, but he suddenly thought of something.

"You are in the immortal realm but have the strength of a heavenly emperor! You are that scoundrel Ryukyu!"

Yin Devil Sovereign roared because he couldn't think of anyone else who possessed such strength while being in the immortal realm.

"You surprisingly dare to mention my master's name. I must kill you today," Li Yunmu said with a sneer.

"Your master? So that little thing that snuck inside a few days ago was you? I hadn't expected that you would go to the place of that scoundrel Ryukyu. It seems like he had nurtured you well."

When Yin Devil Emperor heard Li Yunmu call Heavenly Emperor Ryukyu his master, he understood everything. He hadn't expected that Li Yunmu would surprisingly possess such formidable potential and grown so strong in a short time.

"I should've exterminated you at that time, hmph. That old bastard Ryukyu, I shouldn't have left him alive!" Yin Devil Sovereign said with hatred in his voice.

Although he was unable to do anything to Li Yunmu, he still didn't intend to die. He circulated the energy in his body and ignited a large spell.

"Want to kill me? You also won't survive! Go die, youngster!"

After those words, the large spell shattered with a bang, and a loud explosion occurred in the Yin Imperial Palace.

Li Yunmu rushed forward. This level of explosion couldn't affect the present him.

A sneer was even on his lips. "Using old tricks, do you think I am an idiot?"

Li Yunmu discovered that a wisp of Yin Devil Sovereign's soul had attached itself on the Solitary Ignition Sword. Fortunately, Li Yunmu knew about this, or else Yin Devil Sovereign would've been able to escape.

Li Yunmu covered the Solitary Ignition Sword with a flame, and the wisp of Yin Devil Sovereign's soul dissipated.

"Death goddess will take revenge for me! May the glory remain with me!"
