Li Yunmu was different, however. He was a great principal golden immortal powerhouse for a long time, so how could he not sense their presence. But even if he let their daggers reach his body, he wouldn’t be injured in the slightest.

It was because of the restriction on the space-time spirits. In every generation, only one of them could break through the tribulation passing stage and enter the immortal realm. That person would then become the leader of that generation.

Li Yunmu soon discovered that one of the five space-time spirits attacking him was injured. It should be the one who had tried to take him down previously.

It was quite a surprise that instead of escaping from the Yin Imperial Palace, it called its companions and continued to sneak attack young talents.

Apparently, the space-time spirits had some deep and mysterious connection with Ryukyu Sage.

At that moment, Li Yunmu could clearly sense the killing intent in the eyes of the space-time spirits. Their daggers wanted to taste his blood as soon as possible.

Li Yunmu’s body jolted when his powerful presence erupted. Instantly, the five space-time spirits were blown away as if they had been struck by a hammer. They coughed out mouthfuls of blood and were unable to stand up, but he could still sense their weak breath.

Li Yunmu didn’t intend to take their lives, so he hadn’t attacked using black energy. He was extremely curious why the space-time spirits had pledged their lives to defend the palace hall.

When Li Yunmu took a few more steps and stepped out of the hall, a strong smell of blood came from behind him. That’s right, it came from behind him.

When he turned around to take a look, the hall had changed completely. The sight of it filled his heart with endless resentment.

Countless mangled corpses lay in the hall. The blood of the majority of them had already been drained, leaving behind only dried body parts lying on the ground.

After seeing that, Li Yunmu finally understood what had happened to the young talents who had come to Ryukyu Palace Hall. Their deaths were related to the space-time spirits.

Li Yunmu took a cursory glance over the whole area and discovered that the blood was flowing through specific grooves on the ground.

They created a large spell.

“This is… spirit refining spell!”

Li Yunmu recognized the large spell and its purpose. The spirit refining spell was one of the few true spells created by the ancient spell race.

It had only one use, and it used the souls of other people to replenish the soul of the spell caster, thus reinforcing their spirit.

“It seems like Ryukyu Sage still hasn’t given up. His willpower is great, but what’s the use of it. All struggle is futile,” Li Yunmu said indifferently.

At that moment, he also understood the use of Yin Imperial Palace. What supreme yin attributes treasure, what countless treasures, all of them were only bait to attract people.

Li Yunmu hadn’t expected that the grand Ryukyu Sage who had such great reputation and died to suppress evil with his own body, which would save the world, would actually be someone thirsty for power.

In the ancient times, immortals were like dogs, emperors were present everywhere, while bigshots like sovereigns illuminated the heavens. It was an unprecedentedly glorious time for the world, based on a few remaining records

But a great change had happened in the world at that time. A person called Yin Devil Sovereign appeared in the world. No one knew where he came from, but wherever he went, he massacred people, which gave rise to a crisis.

Yin Devil Sovereign was extremely powerful, so almost all the emperors and sovereigns went to duel with him, which lasted for several years.

In the end, Yin Devil Sovereign died, but many powerhouses also perished with him. Afterwards, the sovereigns were completely wiped out, and the essence of the world was greatly ruined. The world fell into a state of crisis.

Almost every region’s experts had perished in that battle, but after Yin Devil Sovereign was exterminated, the supreme yin sovereign pearl which was his supreme treasure, fell into the world.

The instant this treasure emitting formidable yin energy descended, its yin energy enveloped the entire land, causing the world to degrade further.

Ryukyu Sage, who was one of the few remaining experts after the great war, came out without hesitation. He attacked the yin pearl to suppress it, but since it was a sovereign level treasure, he should have been unable to suppress it with his strength.

However, during the war, the yin sovereign pearl had suffered irreparable damage. It was the reason why it fell to the immortal realm and became a supreme immortal treasure.

Because of this, Ryukyu Sage was able to suppress it with his strength and the world could recover.

After that, Ryukyu Sage’s name spread around the world at the speed of light, and the yin sovereign pearl turned into Ryukyu Spirit Pearl.

But Li Yunmu now learned that Ryukyu Sage coveted the yin sovereign pearl rather than caring about the world. Otherwise, why would such a righteous person become so cruel and not even hesitate to use the vitality of youngsters to recover from his injuries.

From that discovery, another thing came to make sense—why only those who had attained tribulation passing stage or higher level cultivation could enter the Yin Imperial Palace. It was because the soul refining spell could only absorb the cultivation of the past hundred years.

Moreover, if the blood of someone whose cultivation wasn’t sufficient entered the spell, it would reduce the quality of the spirit refining spell.

Once Li Yunmu learned the aim of Ryukyu Sage, he didn’t have the slightest intent to let the space-time spirits go. The black energy moved in his hand and instantly wrapped around the space-time spirits.

When the space-time spirits saw the attack, they were extremely frightened and began to shout in incoherent voices. It was impossible to say whether they were crying or cursing.

But Li Yunmu didn’t feel the slightest bit of pity toward the little devils. He squeezed the energy using his hand, and the space-time spirits turned into a pile of flesh.

Li Yunmu turned around then and left the great hall. He climbed up the stairs, and when he reached the final stair, the scene before his eyes changed.

“Could it all be an illusion?”

Everything in front of Li Yunmu’s gaze became illusory. The walls around him and the path under his feet disappeared. He found himself floating in the void at that moment.

Li Yunmu spread out his divine sense and began to investigate the place. After doing that, his frown deepened.

He discovered that the place where he was standing wasn’t an illusion, but rather a true void.
