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

Placing the Demon-Sealing Tower here also requires setting up some corresponding formations around it. These formations can provide energy for the Demon-Sealing Tower and also keep irrelevant cultivators out.

This one step alone took ten days of work.

When the last formation was set up, Sun Yi and his group gathered at the main square of the Demon Locking Tower. This square was located in front of the Demon Locking Tower and was created by Sun Yi and his group using great magic. The square was over two hundred miles in diameter, which was very large.

"Elder Zhou, have you finished checking the formation?" Sun Yi asked Zhou Tong.

Zhou Tong nodded: "We've checked it three times and confirmed there are no problems. We can open the Demon-Locking Tower now."

"Alright, let's begin then. Changqing, immediately arrange for someone to send all those demon kings over," Sun Yi instructed Changqing.

"Okay, Master."

Changqing quickly began making arrangements, immediately sending people to teleport the captured demon king to the vicinity, and then boarding the Qingyun warship to head towards the location of the Demon Locking Tower.

Soon after, a massive Azure Cloud warship hovered over the plaza, and a group of demon kings were brought out.

Among them were forty-one demon kings at the half-step demon lord realm, more than two thousand fifth-order demon kings, and tens of thousands of fourth-order demon kings.

A dense swarm of demon kings appeared in the plaza, their demonic eyes flashing with an eerie light as they gazed at the colossal tower standing beside it.

Sun Yi simply glanced at the demon kings and then ordered, "Send them in. Demon kings at the half-step demon lord level should be sent to the thirtieth floor or above, fifth-order demon kings should be placed between the twentieth and thirtieth floors, and fourth-order demon kings should be placed on the twentieth floor below."

"Yes!"

The human cultivators, who were already prepared, immediately flew over and brought the group of demon kings into the Demon Locking Tower.

In reality, these demon kings thought that Qingyun Sect had simply arranged accommodation for them, but they had not yet realized the seriousness of the matter.

The demon kings of the four major demon clans in the group were also somewhat nervous and very worried.

Sun Yi naturally noticed the Sea Serpent King, Blood Shark King, and other demon kings in the group, and directly transmitted his voice to them: "You guys go in first, I'll arrange for someone to pick you up right away."

Hearing Sun Yi's telepathic message, the demon kings of the four major demon clans felt somewhat relieved.

"What are you trying to do?" the patriarch of the Golden Dragon Clan questioned the crowd with a grim expression.

"I'll give you a different place to live." Sun Yi glanced calmly at the patriarch of the Golden Dragon Clan, then waved his hand and ordered his men to take them into the Demon-Locking Tower.

A group of demon kings who were half-step demon lords naturally realized that this demon-locking tower was no ordinary building. From this demon-locking tower, these top demon kings all felt immense pressure.

However, now that it has fallen into the hands of the human race and its demonic power has been sealed, it has no way to resist and can only be taken into the Demon Locking Tower.

At the bottom of the Demon-Sealing Tower, there is a special teleportation hall that can directly teleport you to the various floors of the tower. Sun Yi and his group followed them in.

The teams immediately separated, and the forty-one half-step demon lords were all teleported to the thirtieth floor. The thirtieth floor of the Demon Locking Tower had a ring of a thousand rooms.

These forty-one demon kings, each at the half-step demon lord level, were each locked in a separate room.

After being led into a room, the Golden Flood Dragon King began to observe it. He noticed that the room clearly employed spatial manipulation techniques; although it didn't appear very large from the outside, the interior space was several thousand feet in size.

"Such powerful spatial techniques! Could this be a powerful spiritual artifact from the spirit realm?"

With the Golden Flood Dragon King's discerning eye, he could see that this Demon-Locking Tower was no ordinary artifact; it was a powerful sixth-order spiritual weapon. He did not believe that the humans of the mortal realm could forge a spiritual weapon of this quality.

After observing carefully for a while, he found nothing unusual in the room, so he sat down cross-legged in the center of the room.

Despite having his demonic power sealed, the Golden Flood Dragon King, as a powerful being at the half-step Demon Lord level, can still use the power of his controlled domain to absorb the spiritual energy of heaven and earth to restore his strength.

Sooner or later, the seal on the demonic power within him will be broken, and the Golden Flood Dragon King has no doubt about that.

The entire Demon Locking Tower was bustling with activity. Even though it housed 100,000 demon kings, it still only occupied one-tenth of the space.

Soon, Changqing reported to Sun Yi: "Sect Leader, all of these demon kings have been imprisoned in the Demon Locking Tower!"

"Okay, arrange to transfer the remaining demon kings from the Demon Locking Tower here as soon as possible, and imprison them all in this Demon Locking Tower."

"it is good."

After giving his instructions, Sun Yi told the others to wait on the thirty-sixth floor, while he teleported away from where he was and reappeared at the door of a room on the twentieth floor.

With a thought, the door to the room opened directly. The Sea Serpent King, who was locked inside, was startled by the noise and hurriedly looked towards the door.

Upon seeing Sun Yi appear at the door, the Sea Serpent King hurriedly stepped forward and bowed respectfully to Sun Yi: "Your subordinate greets Sect Leader Sun."

"Alright, you're all on the same side, no need to be so polite. I'll take you to where you should really be." After saying that, Sun Yi walked directly to the room next door.

Soon, the other fifth-tier demon kings of the four major demon clans who had been locked in the adjacent room were also released. Their unease dissipated after seeing Sun Yi.

Currently, the four major demon clans have a total of eleven fifth-tier demon kings, whose strength has increased many times over compared to before.

However, even though their strength has reached this level, their awe of Sun Yi is even stronger than before. They know very well that even if the four major demon clans were combined, they would be nothing more than ants in front of the Qingyun Sect.

Moreover, they owe their current status to the help of the Qingyun Sect.

With a wave of his right hand, Sun Yi enveloped the eleven fifth-tier demon kings in a silver light. The next moment, Sun Yi led them to the thirty-sixth floor of the Demon Locking Tower.

As soon as they regained their footing, the Sea Serpent King and his companions surveyed their surroundings. They saw that there were only five large rooms on this floor, and they were standing in the corridor, unable to see what was inside the rooms.

Sun Yi pointed to one of the rooms and explained, "Room Number One is a room specifically designed to help the four major demon clans enhance their bloodline power. We will find a way to extract the demon bloodlines from the Demon Locking Tower and use special spiritual artifacts to help you refine these bloodlines faster and enhance the bloodlines of the four major demon clans."

"Sect Leader Sun, do you really want to enhance our bloodline?" The Mermaid King looked at Sun Yi with surprise.

In the demon race, bloodline is extremely important. Although the four major demon races also possess bloodlines, they are very weak and can only be considered as low-level beings in the demon race.

The stronger the bloodline, the faster the cultivation speed, the stronger the strength, the greater the potential, and the stronger the suppression of low-level bloodline demon races. Every demon race wants to improve the strength of their bloodline, and even the Jiaolong race wants to upgrade their bloodline to the dragon bloodline.
