Mortals ask the immortals

After saying that, the power of the Dao of the Heavenly Yin Saint burst out and directly penetrated into the stone wall, forcing a passage in the direction of the longest array pattern on the ground.

The Heavenly Yin Saint ignored the others and directly pulled Duan Qing and walked forward along the array pattern.

The Taoist Zuo Yang shook his head helplessly and followed the Heavenly Yin Saint.

The others looked at each other and had to follow.

With the Heavenly Yin Saint opening the way, the crowd traveled dozens of miles underground, and finally came to another underground space along the array pattern.

This space was obviously much larger than the previous one, with a size of a hundred feet. In the center of the space, there was a hollow stone ball half embedded in the ground, but the stone ball had already been broken.

The surface of the stone ball was connected to four simple array patterns, extending in four directions, one of which was the one when Duan Qing and others came.

In addition to the broken hollow stone ball and four array patterns, there was nothing else in the entire underground space of a hundred feet.

Seeing this scene in front of them, everyone was a little speechless.

After a moment of silence, Tianyin Dao Saint confirmed to Duan Qing: "Friend Duan, this place should be located directly below Tiandi City, right?"

Duan Qing nodded affirmatively, "Yes, and the directions in which the four array patterns extend are the locations of the other cities in the Black Prison."

Tianyin Dao Saint fell into deep thought, muttering to himself, "In other words, this array is very likely to be spread throughout the Black Prison!"

"Strange, this array looks simple, but its scale is huge, what is its purpose?"

Shenhuang Yao Saint shook his head helplessly, "It's just a destroyed array, why should Tianyin Dao Saint bother."

Tianyin Dao Saint bit her lip and didn't speak for a while.

She didn't know why she had to figure out the origin of this array. Maybe... she just failed to subdue the Heavenly Dao of the Sui Clan World, and she was unwilling to deliberately divert attention!

The corner of Hantian Dao Saint's mouth twitched, and he turned back to the original path, "Let's go, there's nothing to see!"

Jingdi Dao Saint and the other three scattered Dao Saints didn't say anything, and immediately followed Hantian Dao Saint to leave.

Seeing this, several demon saints from the four saint clans, including the Suzaku Demon Saint, also wanted to leave with him.

Tianyin Dao Saint glanced at Hantian and others who were leaving. Not only did he not leave with them, but he felt stubborn in his heart and told Duan Qing beside him, "Little friend Duan, please use the time law to go back in time. I want to see what the origin of this formation is!"

Duan Qing shrugged helplessly, and without any nonsense, he immediately activated the time law and began to go back in time.

Now that the Heavenly Dao of the Sui Clan World has been destroyed, he doesn't have to worry about being killed by the Heavenly Dao for using the time law. There is nothing to worry about.

And he is also very curious about what the purpose of this formation is.

When they found that Duan Qing had taken action, the Suzaku Demon Saint and others who were about to leave immediately gave up the idea of ​​leaving. Even Hantian and the other four who had already walked into the passage they came from couldn't help but stop and look back at Duan Qing.

Under the influence of Duan Qing's time law, the long river of time that was originally flowing slowly and downstream suddenly flowed backwards violently.

One year, ten years, a hundred years, a thousand years, ten thousand years...!

Soon, the time in the underground space had gone back to more than 100,000 years ago.

However, there was almost no change in the underground space, and it still maintained its previous appearance.

Under the gaze of everyone, time quickly went back to 500,000 years ago, but the situation was the same. The hollow stone ball was still broken, but there was less dust on the ground.

Even without the suppression of the Heavenly Dao, Duan Qing felt a little tired at this time.

Tianyin Daosheng looked a little nervous, and sent a voice to Duan Qing, "Boy, hold on, the Sui Clan World has only existed for more than a million years!"

Duan Qing glanced at Tianyin Daosheng, gritted his teeth, released the Heavenly Thunder Body clone, and worked together with the original body to perform the Time Dao!

550,000 years, 650,000 years, 750,000 years...!

With the joint efforts of Duan Qing's original body and the Sui Clan clone, time went back to a terrifying 1.05 million years ago!

At this moment, Duan Qing's original body and Sui Clan clone have reached their limits. Even if they use all their strength to activate the time law, the long river of time can no longer go back significantly. It is almost stagnant and can only go back slowly with the limit of the sky, and it seems that it will stop completely at any time.

Just when Duan Qing was about to give up, the dust on the ground around him quietly gathered together, and next to the stone ball, a rectangular stone tablet was reorganized.

There seemed to be something engraved on the stone tablet.

"In the first year of Qianshan, the Wuxiang Emperor Sang Tian was sealed in the Black Prison."

Wuxiang Emperor Sang Tian?

In the crowd, Cangsi Demon Saint Niu Er saw the five big characters Wuxiang Emperor Sang Tian on the stone tablet, and his face changed suddenly.

Almost the next moment the stone tablet appeared, a phantom also quietly appeared next to the stone tablet.

It's a pity that everyone's attention was all on the stone tablet. When everyone noticed the phantom appeared, Duan Qing could no longer hold on and had to interrupt the time law.

Before everyone could see what the phantom looked like, the stone tablet and the phantom disappeared in an instant, and everything around returned to its previous state.

Tianyin Daosheng felt very regretful and complained to Duan Qing, "Boy, you really know how to pick the time!"

Duan Qing's face was pale and bitter, "Junior's strength is limited, please forgive me, Your Majesty!"

Tianyin Daosheng saw Duan Qing like this and couldn't bear to continue blaming him. He turned to look at the others, "Everyone, have you seen what is engraved on the stone tablet?"

"Does anyone know who Wuxiang Emperor Sang Tian is?"

Everyone looked at each other. Except for Cangsi Demon Saint Niu Er, the others shook their heads to indicate that they didn't know.

Noticing the abnormality of the Cangsi Demon Saint, the Tianyin Yin Saint's eyes suddenly lit up. He walked up to the Cangsi Demon Saint and asked, "Does Brother Niu know the reason?"

The Cangsi Demon Saint Niu Er was silent for a moment, nodded slowly, and then took out something in front of everyone.

Seeing what Niu Er took out, everyone was shocked.

Niu Er took out nothing but a stone tablet, and this stone tablet was almost exactly the same as the one everyone had just seen.

The only difference was the words engraved on it.

"In the first year of Yuanzhen, the Wuxiang Emperor Sangtian was sealed in Wuxiang Star."

Wuxiang Emperor Sangtian!

It was Wuxiang Emperor Sangtian again!

Everyone was confused and couldn't figure out the reason for a while.

Judging from the stone tablet, both places seemed to have sealed Wuxiang Emperor Sangtian.

And the time was surprisingly similar.

The first year of Yuanzhen was undoubtedly the beginning of Yuanzhen's opening up of the Immortal Spirit Alliance World, and the first year of Qianshan was the beginning of Qianshan Prisoner's opening up of the Sui Clan World.

The existence of the two worlds is almost the same, more than one million years.

The only people who could leave this stone tablet at the beginning of the two worlds should be the masters of the two worlds, Yuan Zhen and Qian Shan Qiu.

But why did Yuan Zhen and Qian Shan Qiu seal a Wu Xiang Emperor Sang Tian in the Immortal Spirit Alliance World and Sui Clan World respectively?

Is Wu Xiang Emperor Sang Tian just a code name, and they are actually two people, or is there another hidden story?
