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

Nowadays, the Demon Refining Tower is only open to the public for ten days each year. If you want to enter the Demon Refining Tower to visit the imprisoned Demon King, you need to enter the Demon Refining Tower at a specific time.

Such a setting will not make the Demon Refining Tower chaotic and avoid unnecessary trouble.

But Sun Yi and his companions were completely unrestricted when they entered the Demon Refining Tower. At this time, Sun Yi's huge spiritual sense spread out, and the prisoners at the bottom of the Demon Refining Tower were all covered by him.

The demon king's body in the prison was blocked by rune chains and sealed in the prison. Most of the usable materials on his body had been taken away.

Sun Yi discovered that the aura of these demon kings was weaker than when they were first captured.

Compared with before, there is an additional tube covered with runes on the backs of these demon kings. One end of these tubes is inserted into the body of the demon king, continuously extracting demonic power from the demon king, and the other end goes straight upwards along the prison.

Sun Yi's spiritual consciousness went up along the duct to the top floor of the Demon Locking Tower, where he saw a huge enclosed cauldron.

This tripod furnace has a diameter of more than ten feet, four legs at the bottom, no lid on the top, and is completely enclosed. The surface is covered with mysterious runes.

One tube after another was connected from the bottom, around the bottom of the cauldron and into the cauldron. A steady stream of demonic power was injected into the cauldron through the tubes.

A mysterious flame formation was arranged under the cauldron, and a purple flame was burning in the flame formation.

The cauldron was wrapped in the purple extreme flames, and the runes on its surface were glowing. Inside the cauldron, the demonic power extracted from the demon king's body was being gradually refined.

This cauldron extracts the demonic power of the demon kings in the Demon Locking Tower, keeping these imprisoned demon kings in an extremely weak state.

Even if the quality of the Demon Locking Tower is not very high, there is no need to continue to use the Wanbao Killing Formation to suppress it, and there will basically be no problem.

This arrangement not only makes use of the demon power that these demon kings are constantly recovering, but also solves the hidden dangers of the Demon Locking Tower.

After being refined, these demonic powers are injected into four training spaces not far away through four conduits above the cauldron.

Among these four training spaces, there is one top-notch training space, and the other three training spaces are also fifth-level training spaces. They are now specially allocated to the demon kings of the four major demon tribes for use.

Now, dozens of demon kings from the four major demon clans gathered on the top floor to practice, most of them were the demon kings from the original four demon clans.

These demon kings had acted with the Qingyun Sect before, and many of them were sent to the Qingyun Sect for training. After this period of training, the realms of these demon kings have improved a lot, and basically they have reached the late fourth stage.

Sun Yi and others climbed all the way to the top floor of the Demon Locking Tower. When the demon kings of the four major demon tribes who were practicing saw Sun Yi and others coming, they immediately stood up and saluted Sun Yi and others respectfully.

"Greetings to Sect Master Sun, and to all the fellow Daoists of Qingyun Sect."

The dozens of demon kings looked at Sun Yi with eyes filled with admiration. What human race? What demon race? In the eyes of these demons, Sun Yi was their reborn parent. If it weren't for Sun Yi's help, they would never have been able to reach their current level in such a short time.

These demon kings once struggled hard in the demon clan but saw no hope of promotion. However, after following Qingyun Sect, their cultivation improved by leaps and bounds, and they even saw the hope of being promoted to fifth-level demon kings. Therefore, even without the restrictions in their bodies, these demon kings are very loyal to Qingyun Sect.

The saying "whoever gives you milk is your mother" also works in the demon clan. Moreover, the competition among the demons is even more intense, and the fighting never stops. The loyalty of these demon kings to the demon clan is very low.

Sun Yi looked at the demon kings with a smile on his face: "Congratulations to all fellow Taoists. In such a short period of time, your realms have been elevated to such a high level. This is cause for celebration."

"We have reached our current level thanks to Sect Leader Sun." The second elder of the Sea Snake quickly stepped forward. He has now also cultivated to the late fourth stage and has made great progress.

"Yes, without your help, we would not have been able to cultivate to the current level in such a short time." The third elder of Blood Shark also spoke hurriedly.

"Master Sun, you are our great benefactor. We will never forget this kindness!" The elders of the Blue Crab Clan also looked at Sun Yi with gratitude.

Sun Yi smiled and waved his hand: "Don't be polite, everyone. Although you are all demons, we are now one family. There is no distinction between us. Helping you is helping ourselves."

"By the way, are you satisfied with these four training spaces now? How do they help you in your training?" Sun Yi asked with a smile.

"Good! Very good! This method of practicing by directly absorbing pure demonic energy is even five times faster than before. It is precisely because of this that our realm can be improved so quickly." The second elder of the sea snake was excited.

"Your family is truly amazing. You actually thought of using this method to help us improve our cultivation. It's simply a miracle!"

"Only your family could come up with such a plan."

These demon kings were all very excited because the Qingyun Sect extracted the demonic power from the demon kings in the Demon Locking Tower, purified it, and then injected it into the cultivation space, making it very easy for these demon kings to absorb and refine it. They had never heard of such a cultivation method before.

"It's good that it's useful for your cultivation. This is a cultivation method specially developed and designed by our sect for you. In the future, all of your four major clans can use this method for cultivation." Sun Yi nodded with a smile.

At this moment, a strong wave of demonic power suddenly came from the top-level training space next to it. This wave of demonic power was so strong that it could be transmitted through the training space.

In an instant, everyone's attention was focused on the training space.

"It's Fellow Daoist Haiyun who has made a breakthrough!"

"Could this mysterious aura be the power of the law? It seems that Fellow Daoist Haiyun has gained a lot."

"Yes, with the power of Daoist Haiyun's bloodline, it is too difficult to comprehend the power of the law. If Daoist Haiyun comprehends the power of the law, it will be easier for him to reach the fifth-level demon king realm."

"I wonder what kind of law and power Old Eight has comprehended." The Second Elder of the Sea Snake looked towards the training space with some excitement.

"Haha, I didn't expect that we would come here just in time to see the Eighth Elder breaking through. This is quite a coincidence." Sun Yi looked at the training space with a smile on his face.

The Eighth Elder of the Sea Snake had previously brought back the Forbidden Spirit Stone for the Qingyun Sect, making a huge contribution to the Qingyun Sect. He was rewarded with the opportunity to cultivate to the late fourth stage for free, and was also promised that the cost of cultivating to the peak of the fourth stage would be halved.

The Eighth Elder of the Sea Snake took advantage of this rare opportunity and spent his own resources. With the help of this top-notch training space, his training speed was very fast, and he reached the peak of the fourth level a long time ago.

Suddenly, a figure flashed by the teleportation array next to them, and the Eighth Elder of the Sea Snake appeared in everyone's sight. At this time, the aura of the Law of Water and the Law of Gold was still entwined around him.

"The power of two laws!"

The Eighth Elder of the Sea Snake had already reached the peak of the fourth level at this time. He also comprehended the laws of water and gold, and his strength skyrocketed.

However, when he saw the situation around him clearly, he hurriedly ran to Sun Yi and bowed respectfully to Sun Yi and the others: "Greetings to Sect Leader Sun, and to all fellow Taoists!"
