My disciple's cultivation returns ten thousand times, so I have to be invincible.

"But during this experiment, some useful results were also produced."

"For example, the restrictions on this Prisoner Planet."

"Have you three ever thought about who created and set up the restrictions on this Prisoner Planet that can offset Xu Yuan's power?"

Zhong Qing and the other two looked at each other, still without saying anything.

They had no knowledge of the world outside Xuyuan before, and had no idea about the level of this restriction or whether it was special compared to the outside world. Naturally, they would not question it.

Cang Xuanzi said calmly, "The power of the Void Abyss has always been one of the most terrifying natural forces in the starry sky. I'm sure you've all experienced this yourself. Even a True Immortal would expend a tremendous amount of energy to resist it."

"And yet, on this Prisoner Planet, there are restrictions that can offset the power of the Abyss with relatively minimal consumption."

"Even if such a restriction were placed within the Void Qi Immortal Zone, it would be beyond the reach of most people, even True Immortals. And this Prisoner Star is simply used to imprison those who haven't even reached the True Immortal level."

"Isn't this very unusual?"

At this time, Yumen Wang and others were also listening attentively to Cang Xuanzi's words.

Hearing the implication of his words, he didn't take the prisoners seriously at all, and couldn't help showing his anger, but at the same time, he was indeed deeply thoughtful about what he said.

Indeed, such a large-scale operation was arranged in this ghost place that even the True Immortals found difficult to deal with.

Just to hold some ordinary prisoners?

"Besides that, there are many strange and abnormal places on the Prisoner Planet."

"For example, the prisoner's mark."

"The prisoner's mark itself contains immortal power, and it can even be passed down through bloodlines from generation to generation."

"That's not just in name, but real immortal power."

"This method is also not something that ordinary True Immortals can do."

The next moment, Cang Xuanzi slowly opened his mouth and said something shocking.

"This is because these six prisoner stars were just experimental subjects at the beginning."

"The reason these six great stars were created is because they were outposts established by one or more great figures in the past in order to find a way to enter the Abyss."

"The final result is the restrictions on these six prisoner planets."

"As for using this place as a prison to hold prisoners, on the one hand, it was to use these prisoners for experiments to see how effective the restriction was, and on the other hand, it was to recycle waste after it was successful."

"Anyway, after they created the restriction and found a way to enter the Abyss, this place lost its other functions."

These words were spoken lightly, but when Prince Yumen and the others heard them, they were all shocked.

It turns out that this is the reason why the Prisoner Star was born.

The Prisoner Star was not placed in Xuyuan for the purpose of holding prisoners.

But in order to enter the Urobuchi, he created the Prisoner Star here and later used it as a prison.

As if he could sense the shock of Prince Yumen and the others from a distance, Cang Xuanzi chuckled.

"Yes, the Prisoner's Mark was created in the same way."

He looked at Zhong Qing and the other two again and said, "The origin of the laws of the True Immortal transcends the laws of heaven and earth. Therefore, the power of the True Immortal can resist the power of the Void Abyss and keep you unaffected."

"But you three have naturally experienced it before. It's such a huge drain. Even at the three-dimensional level, using your immortal power to resist, you can't hold out for long."

"But the prisoner mark that all these lowly prisoners bear can free their spirits and wills from the influence of the power of the Abyss with just a trace of this mark and a trace of immortal power."

"Obviously, this was also an early preparation for entering the Urobuchi."

"If I could engrave something similar into my soul and will, and then abandon my physical body, would I be able to pass through the outer layer of the Abyss and enter it?"

This time, even Zhong Qing and the other two were a little surprised.

Zhong Qing's eyes flickered as he thought of something.

Bai Ze once said that among those who entered the Ninth Heaven, was there anyone who came in through this method?
