Hearing this, Old man Qingyi and the old man in red frowned. In the middle, Old man Zi Yi shook his head and looked at Beigong Changfeng, “Brother Changfeng, this move of yours is really ruthless. If that’s the case, wouldn’t the rest of the people on the first to eighth floors of the Thunder Heaven Prison be wiped out as well?”

“Hmph …”

Beigong Changfeng coldly flicked his sleeves. “I said that those who succeed in great things don’t care about small matters. Besides, there are some extremely vicious people imprisoned below. So what if they die?”

“As expected of Brother Changfeng, tall, really tall.” Old man Zi Yi gave him a thumbs up, and his expression was a little strange.

“Alright, don’t waste any more time.”

Beigong Changfeng frowned. He seemed to be getting impatient. After he finished speaking, he flew towards the east of the formation. Old man Qingyi and the old man in red exchanged glances and headed north and south. The remaining Old man Zi Yi looked around and finally had to head west.

At this moment, the four of them were each in charge of one side. They chanted incantations and formed seals with their hands. At the same time, they sent out a profound energy into the restriction array. The entire array instantly shone with a bloody light, reflecting the entire night sky to a bloody color.

“What’s wrong with Thunder Heaven Prison …”

In Peerless City, it was clear that many cultivators had seen four streaks of bloody light soaring into the sky from the prison. At the same time, they also felt a terrifying aura of restriction. Many people became panicked and uneasy.

“It can’t be that person from forty years ago, right? How terrifying! What happened? Why didn’t Senior Changfeng inform us beforehand?”

The city began to panic, but soon, Beigong Clan’s disciples went to maintain order. “Everyone, don’t be nervous. Right now, Master is stabilizing the restriction formation of the Thunder Heaven Prison. Everything will be fine …”

“Why is the restriction of the Thunder Heaven Prison loosened? Could it be that the person from 40 years ago was about to rush out from below?”

“Nothing. Master is just stabilizing the formation. Everyone, don’t be nervous. Please don’t spread the rumors. All of you, go back …”

Under the words of the fourth disciple of Beigong Clan, order was quickly restored in the city. However, there were still people standing outside, staring at the sky-soaring bloody light from the Thunder Heaven Prison. Some of them with higher cultivation could clearly feel that the restrictive aura was extremely terrifying. It was definitely not a stable formation …

…

Below Thunder Heaven Prison, the two of them could clearly feel that the restriction had suddenly increased by a lot. Xiao Chen frowned and said, “Qianluo, what should we do? The restriction of this formation is too powerful. I’m afraid it’s very difficult for us to get out of it …”

“Don’t be nervous. Go up and take a look.”

Xiao Chen frowned slightly. As he spoke, he walked up. Qianluo carefully followed behind him. The more the two of them walked up, the more they could clearly feel the terrifying restriction. If they collided head-on with the restriction, it was likely that no matter how high one’s cultivation level was, they would have to suffer heavy injuries.

“Let me out … Let me out!”

“Is there anyone? Help me … Hey! Those two outside, save me! I have a way to get you out of here …”

When the two of them reached the upper floors, they heard many people shouting for help in the prison. Qianluo was still somewhat concerned about who these people were and was imprisoned here. However, Xiao Chen ignored these people and continued to walk upwards. When they reached the third floor, the restrictions on the upper floors were already very heavy, and they were unable to continue.

“I can’t go anymore …”

Looking at the wisps of blood mist constantly spreading down from above, Qianluo immediately stopped and looked at Xiao Chen. “Childe Xiao, what should we do? The restrictions are getting heavier and heavier, and they are still seeping down. We must return to the eighth floor …”

“Wait a moment …”

Xiao Chen raised his hand and closed his eyes. He focused on sensing the restriction and Formation Power. Seeing that he had closed his eyes, Qianluo immediately retreated to the back. He was quiet and did not disturb him.

After a while, Xiao Chen opened his eyes. Qianluo immediately stepped forward and pulled him down the stairs. “Childe Xiao, watch out …”

The red mist on the stone staircase filled another layer, and it almost enveloped Xiao Chen.

“Childe Xiao, have you sensed anything?” After pulling him down, Qianluo asked nervously.

Xiao Chen looked at the layers of red mist and said with concentration, “This restriction formation has been here for about thirty to forty years. It was not created by the four people above.”

‘”That’s” Qianluo frowned. In other words, this formation wasn’t actually used to deal with Childe Xiao.

Xiao Chen said, “It was laid down by at least four experts at the True Cave Stage, and even … experts at the True Cave Stage and above.”

“What …”

Hearing what he said, Qianluo was stunned. Four True Cave Stage experts, even above True Cave Stage, had set up formations …

“Yes.” Xiao Chen nodded. At this moment, his brows furrowed even deeper.

Qianluo looked at him and whispered, “If the two of us work together, what is the possibility of breaking it … what is the probability?”

“Not even 10%.”

Xiao Chen shook his head and said, “This formation is not only set up by four or more experts at the True Cave Stage, it is also not an ordinary formation. Even if there are no four people outside, with our current cultivation, it is impossible for us to break it.”

“Then … then …”

Qianluo’s face turned slightly pale as he looked behind him. He seemed to have grasped the last resort. He turned around and said, “If we release all the people in this prison, can we work together to break this restriction formation?”

Xiao Chen still shook his head, “Those people are unsafe. It’s useless …”

“Then, there’s no other way …”

Qianluo’s face became even paler, and his expression became somewhat dazed. He suddenly raised his head and looked at Xiao Chen, saying, “Childe Xiao, I’m sorry, it was all me … It was all me who hurt you. If it wasn’t for me, if it wasn’t for me …”

Xiao Chen looked at her and calmly said, “Back in Tomb of Gods and Demons, we were surrounded and killed by tens of thousands of people. Do you think that was scary then, or is it even scarier now?”

“I…”

Qianluo was stunned by his question and was speechless. Xiao Chen looked at her and continued, “Afterwards, we went deep into the forbidden area of Tomb of Gods and Demons and passed through the place where the Fiendgods reside, as well as the forbidden area of the Great Fiendgods. Do you think it was scary then, or is it scary now?”

Qianluo was still staring blankly at him without saying a word. Xiao Chen continued, “In the end, we came out of Tomb of Gods and Demons. We were trapped in the Void Chaos Realm. Do you think that was scary, or is it scary now?”

“Childe Xiao …”

Qianluo was stunned. She immediately understood. Back then, she was in such a dangerous situation with him. It was countless times more terrifying than now. In the end, she had also rushed out. Now, why would she fear this restriction formation?

“Let’s go. Let’s go back to the eighth floor first.”

As Xiao Chen spoke, he walked back. The two of them returned to the eighth floor. By the second day, the restriction had already penetrated into the fifth floor. In at most two days, the terrifying restriction would penetrate into the floor they were on.

As for the people on the third and fourth floors, their lives were unknown. It wasn’t that Xiao Chen deliberately didn’t save them, but that the restrictions in each floor were very heavy. If he rashly moved, he might not be able to open them, but instead, it would cause trouble.

However, Luo Die’s eighth floor did not have any restrictions. It was obvious that Beigong Changfeng had already arranged it.

“Childe Xiao, the restriction has reached the fifth level …”

Just as he was deep in thought, Qianluo hurriedly ran down. Xiao Chen opened his eyes and asked, “How much longer will it take to reach the sixth floor?”

“About … three hours.” Qianluo panicked and whispered, “Childe Xiao, what should we do …”

“Let me think …”

Xiao Chen slowly frowned. He thought to himself that this formation was set up by four experts at the True Cave Stage and above several decades ago. There was no need to say how formidable it was, but the people in this prison were not necessarily very formidable. The restrictions on each floor of the dungeon were already capable of trapping those people. There was no need for such a formidable restriction formation. What was the reason for that?

It couldn’t have been that Beigong Changfeng had anticipated this dozens of years ago, so he asked someone to set up such a formidable formation here in advance, right? Then the only possibility is …

At this moment, Xiao Chen slowly looked under his feet. Qianluo saw him looking at the ground beneath his feet and immediately understood, “The ninth floor …”

“That’s right, the ninth floor.”

Xiao Chen looked at the ground beneath his feet and said, “There should be a ninth floor in this dungeon. Furthermore, there is a very powerful person sealed on the ninth floor. The restriction array on top of it was set up to seal this person …”

“This …”

After hearing what he said, Qianluo immediately began to carefully search the surroundings. However, no matter how she searched, she was unable to find the path to the ninth floor. There was simply no path to the next floor.

Xiao Chen said, “The ninth floor has already been sealed. It is very likely that it is an extremely powerful illusion …”
