To be the best leader, you must also be the strongest leader!

The Human Emperor flags above the heads of these demon kings released rolling black fog that enveloped the people below, and the surrounding stone tablets also released strange light that enveloped these demon kings.

These forces were integrated through the formation, forming a very terrifying refining force that enveloped these demon kings.

The demon kings present were already very weak, and their demonic power was almost gone. Under the influence of this terrifying refining force, their defenses were weaker than paper.

The defenses of these demon kings were melted in an instant, and then their bodies also melted quickly, leaving them with no power to resist at all.

"No...spare my life..."

"Damn it! Why is this happening?"

"You despicable human race, you will not live well!"

……

Cries of begging for mercy and angry curses filled the entire space, but soon disappeared because in just a moment, all the demon kings except the Ice Demon King had been completely refined.

Their demon bodies have disappeared, leaving only their demon souls remaining in the air, which are swallowed one by one by a whirlpool that appears on the ground.

"Damn it, how did they find out?"

The Ice Demon King had an extremely ugly expression on his face. He was not stupid and immediately realized that the Qingyun Sect's target was him, because there was no need to do this to deal with these fourth-order demon kings.

"Damn human race, I will not be refined so easily!"

A powerful demonic power suddenly erupted from the Ice Demon King, and at the same time, a strange domain power spread out with him as the center.

In an instant, the void within ten feet around the Ice Demon King seemed to be controlled by him.

Within ten feet, there were ten demon souls of fourth-level demon kings, which were about to be swallowed by the black vortex below, but suddenly and strangely stopped in the void. As the Ice Demon King opened his mouth and sucked, the ten demon souls were swallowed into his mouth.

The whole process was very fast. Sun Yi and his team could see the situation inside the Demon Refining Tower from outside. Seeing this scene, Sun Yi's expression became even more solemn.

"As expected of a Half-Step Demon King, his methods are indeed not simple. Seniors, please give it your all."

For a moment, the powerful people around madly injected their magic power into the formation, not daring to hold back at all. With the injection of these magic powers, the Demon Refining Tower in the center of the formation suddenly burst into dazzling light, and the aura it emitted also increased dramatically.

The Ice Demon King has now transformed into a blue-haired young man with two horns on his head. He looks to be in his twenties and has a pair of blue demon eyes, which makes him look very strange.

He made seals with his hands, and blue light shone all over his body. A terrifying cold air emerged, and then turned into a blue dragon that surrounded his body.

This blue dragon is vivid and alive, circling around the Ice Demon King, resisting the refining power that is constantly approaching from all sides.

Although this fifth-level, fifth-grade demon-refining tower was blessed with the magical powers of many powerful men, it was still blocked at this moment and was in a stalemate for a while.

"Is this the strength of a Half-Step Demon King? This should only be his soul fragment. He has only possessed the Black Turtle Demon King for such a short time, yet he can still unleash such terrifying power."

"It's really a bit scary. If it weren't for the Sect Master's caution, I'm afraid it would have taken over my body by now. It seems that we should be more careful with the demon clan in the future."

"Yes, although we had some advantages in dealing with the demon tribe before, it seems that we still cannot be careless now." Sun Yi nodded solemnly.

Inside the Demon Refining Tower, the Ice Demon King had an extremely ugly look on his face. He just shook his body and instantly appeared at the top of the space. His right claw, wrapped in blue demonic power, grabbed towards the top with force.

In an instant, the Ice Demon King's right claw turned into a dragon's claw, and it was a huge dragon claw made of ice.

This dragon claw emitted a terrifying cold air, and the void around it seemed to be distorted.

In an instant, the Ice Demon King's claw slammed heavily on the top of the Demon Refining Tower.

boom!

With a loud bang, the entire Demon Refining Tower shook violently. A layer of transparent barrier emerged at the place where the dragon's claws hit, blocking the attack.

Although the attack was blocked, the barrier was shaking violently, and a terrifying chill spread in all directions with the dragon's claws as the center.

"What a powerful force! If I hadn't been prepared, I'm afraid the Demon Refining Tower would be destroyed with just one blow." Sun Yi's expression was extremely solemn at this moment.

"Too strong! This isn't even his true self. I wonder how much of his power this clone has."

"This is the first time we fight against a Half-Step Demon King. I didn't expect him to be so strong." Taoist Xuanling's eyes flashed with brilliance.

Inside the Demon Refining Tower, the Ice Demon King looked at the transparent barrier in front of him, and a cold light flashed in his demon eyes.

"You bunch of damned humans, when I get out, I will make sure you are in trouble!" The Ice Demon King was furious and continued to mobilize his demonic power. His hands turned into blue dragon claws and attacked the barrier.

"No, if this continues, we will definitely not be able to trap him!" Sun Yi felt the changes in the Demon Refining Tower. Although he had the magic power of these top-level masters in the Spirit Transformation Stage to support him, he could not withstand the crazy attack of this Half-Step Demon King.

"Xiao Qi, Senior Tianshu, Senior Xuanling, I'll take you in to hold them back, while the rest of you use all your strength to activate the refining power of the Demon Refining Tower!"

"Okay, be careful!"

Sun Yi made arrangements immediately. Xiao Qi was next to him. Tianshu Star Lord and Xuanling Taoist Lord also came to Sun Yi immediately. With a flash of silver light, Sun Yi teleported the three of them into the Demon Refining Tower.

As soon as they came in, the four of them felt the violent force that permeated the entire space. The refining power of the Demon Refining Tower was extremely strong, and the pressure brought to them by the Ice Demon King was also very strong.

The moment Sun Yi and the others appeared in the Demon Refining Tower, the Ice Demon King had already noticed it. He stopped attacking the Demon Refining Tower and turned to look at Sun Yi and the other three.

The moment he saw Sun Yi, a strong light of resentment burst out from the Ice Demon King's eyes, and a terrifying murderous intent erupted from his body.

"Damn human race, I swear to kill you!" The Ice Demon King suddenly turned into a blue light and rushed towards Sun Yi.

At this moment, Xiao Qi had already used all his strength to activate the power of the dragon ball in his body. Colorful light bloomed and terrifying power fluctuations emanated from Xiao Qi's body.

A phantom of a divine dragon appeared behind her, and the powerful bloodline suppression force enveloped the Ice Demon King.

The Ice Demon King felt as if a mountain was pressing down on him. He turned his gaze to Xiao Qi, and a greedy light flashed in his demon eyes.

"This is definitely the bloodline of the dragon clan, which is above the royal family!"

At this time, Xiao Qi had already taken out the Tianlong loudspeaker and directly activated the Tianlong Soul-Destroying Sound. In an instant, a destructive sound wave force swept out, engulfing the Ice Demon King.

In such a small space, the power of the Tianlong Soul-Destroying Sound was extremely terrifying, but Sun Yi keenly discovered that this sonic attack was weakened layer by layer as it approached the opponent. Although the power was still very strong, it did not cause much damage to the opponent.
