After everyone left, Qi Zhiheng and Yang Yitian's attention returned to the formation.

Wu Yin said, "Uncle-Master, the instigator has been caught, and the innocent people have been saved. Is it time to return to the sect?"

Yang Yitian shook his head and said, "No, why are you in such a hurry to go back?"

"Aren't we going back? What are we planning to do here?" Wu Yinyin asked, somewhat puzzled.

Yang Yitian said, "Of course they're staying here to tinker with the formation. Aren't you curious about what they're using this formation for?"

Wu Yinyin thought about it and agreed: "I am indeed very curious." Her gaze turned to Sun Zhong on the ground.

Qi Zhiheng secretly felt regretful, because soul searching was not allowed in the cultivation world, otherwise it would be regarded as demonic, and he did not want to be hunted down by the righteous path.

Without shortcuts, he could only deduce from some details.

"The formation they set up before seems to be for opening the gate." Lin Yu had been arrested a long time ago, and she could hear these people talking about things from time to time. She herself heard a lot of news related to opening the gate.

"What door?" Yang Yitian asked. "Do you know what door it is?"

Lin Yu shook his head and said, "I don't know about that. We are just prisoners trapped in the formation, so we don't have much information to get."

Yang Yitian looked at Sun Zhong, who was trapped on the ground, and asked, "Sun Zhong, why don't you tell me your plan?"

Sun Zhong snorted coldly: "You're dreaming."

"I just don't understand, which sect did you betray the God of Slaughter Sect for? The God of Slaughter Sect is already very powerful, is there any other sect that can offer better conditions?" Yang Yitian was completely puzzled. His family had gone through a lot of trouble to get into the sect as a whole.

Sun Zhong kept his mouth tightly shut, clearly not intending to say anything.

Qi Zhiheng sneered: "I'm afraid they didn't betray the sect, they've just been an undercover agent within our sect all along."

Yang Yitian thought about it and felt it made a lot of sense: "What you said is not wrong, this possibility is even greater."

Sun Zhong's expression changed, but he quickly recovered, all of which was observed by Qi Zhiheng.

"As for why they don't want us to know, it's probably because there's something good here that this guy's sect wants to monopolize. But this is the territory of the Slaughter God Sect, and if they want to take over what's here, they naturally have to drive the people from the Slaughter God Sect away," Qi Zhiheng explained.

The disciples of the Slaughtering God Sect suddenly realized why the outer perimeter of the mountain range had been attacked after they arrived, and later even the town had been attacked. By doing this, they could not only capture the person who used the formation to activate it, but also shift the blame to the Slaughtering God Sect.

When the Slaughtering God Sect leaves, people in the village go missing, which causes the residents of these towns to become xenophobic.

Having been ostracized and having no leads, the disciple of the God of Slaughter Sect had no choice but to return to the sect.

During their time back at the sect, they will have more room to maneuver.

Qi Zhiheng said, "Let's leave the question of what sect he belongs to and whether he has betrayed the sect to the sect's enforcement hall for questioning. I'm sure the seniors in the enforcement hall are better able to get him to talk than we are. Now, I'm more curious about what's inside this sect."

"Shall we open the door first?" Yang Yitian suggested, as he also wanted to go in and take a look.

Qi Zhiheng glanced at the formation, then took a step back. He didn't understand formations: "How do I activate this formation?"

Although Yang Yitian didn't know much about this aspect, he was already familiar with the formation in front of him. He explained, "Just throw those people in. Once enough energy has gathered here, the door will open."

This method is indeed a bit cruel, but they are simply giving someone a taste of their own medicine.

Upon hearing Yang Yitian's words, the disciples of the Slaughtering God Sect eagerly helped to bring over all the prisoners.

Yang Yitian commanded, "Throw them all in."

“I saw they arrested hundreds of people before, is it okay for us to only throw in a few dozen?” Wu Yinyin asked.

Yang Yitian shook his head: "No problem. Before, they mostly threw in Qi Refining stage cultivators, but now we're throwing in Foundation Establishment and Golden Core stage cultivators. We can't match the quantity, but we can make up for it in terms of quality."

The disciple of the Slaughtering God Sect nodded: "I see."

Soon, everyone except Sun Zhong was thrown inside.

Once the number of people was about right, Yang Yitian activated the formation.

Soon, screams of agony echoed from within the formation, but Yang Yitian remained calm.

Qi Zhiheng found it strange, never expecting that Yang Yitian could accept such a thing so naturally.

The screams gradually stopped, and those who had been blocking the way within the formation were reduced to nothing but robes and skeletons.

As the shouting ceased, the ground trembled, and a crack appeared where the stone carvings had been. The crack widened, revealing a square entrance. This was likely what Sun Zhong and his group meant by "opening the door."

"The door is open." Yang Yitian glanced down and saw a stone staircase leading downwards. It was pitch black inside, and he couldn't see anything inside.

Qi Zhiheng probed downwards with his divine sense, but soon, as if attacked by something, his divine sense felt like it was being pricked by needles.

Qi Zhiheng frowned deeply; it seemed the situation inside was somewhat dangerous.

Seeing the open door, Wu Yinyin said excitedly, "Uncle-Master, shall we go in?"

Qi Zhiheng looked at the disciples of the Slaughtering God Sect and said earnestly, "Listen to me first. This is not a place you can get involved in. I just checked it out, and even a Golden Core cultivator would be in great danger inside. So I don't recommend that you go in."

The disciples of the Slaughtering God Sect were somewhat disappointed, but Qi Zhiheng was a Golden Core cultivator. Even if they didn't really believe him, they couldn't argue with him because he spoke to them politely. A Golden Core ancestor was going to search for treasure, and you, a Foundation Establishment cultivator, wanted to go in and get a share of the pie?

Seeing the disappointed expressions on the faces of the disciples of the Slaughtering God Sect, Wu Yinyin knew that she had no choice at the moment, so she volunteered, "Uncle-Master, then we'll stay here and keep watch over the situation outside for you."

Qi Zhiheng said, "No need. You take Sun Zhong down the mountain first. I will go down and investigate the situation myself. If you don't hear from me in ten days, then you should return to the sect and report this matter."

"Wait!" Yang Yitian sensed something in his words: "Why did you say you were alone? I want to go in with you."

Qi Zhiheng said, "It's too dangerous inside. I'm somewhat confident I can go in by myself, but I'm afraid I won't be able to keep an eye on you if you come in with me." He was willing to take Yang Yitian with him if there was danger, but they had to come into contact with objects. If they got separated, it would be bad, and he couldn't guarantee Yang Yitian's safety.

Yang Yitian pursed his lips and argued, "You can't even break the outer formations, there are probably many formations inside too. I have to go in with you to guarantee your safety!"

Qi Zhiheng: "..."

In the end, the two of them went inside together, while the rest of the group led Sun Zhong down the mountain.

To avoid getting separated, Qi Zhiheng and Yang Yitian stayed close together. The passage had been sealed off for an unknown period of time, and they could feel a bit stuffy as soon as they entered. However, cultivators didn't need to worry about whether they could breathe or not; they just needed to hold their breath. They wouldn't have any problems even if they didn't breathe for half a month.

Once inside, he could feel that it was pitch black all around. Qi Zhiheng did not dare to venture out his soul power rashly. The experience of spying on him from the outside had taught him a lesson.

As they moved further away from the entrance, their vision became increasingly difficult. Qi Zhiheng activated a luminous pearl, illuminating the surroundings.

The surrounding area consisted of flat stone walls, with nothing on them, just a simple passageway.

Yang Yiwen asked, "What kind of place are you talking about?"

Qi Zhiheng glanced at the seemingly endless road and replied, "It could be a cultivator's tomb."

Generally, cultivators who are buried in tombs are those who died of old age or who could foresee their own death. Those who died unexpectedly are likely left to rot in the wilderness. When there is still a chance to break through to higher realms, surely no cultivator would be so unlucky as to build themselves a tomb where they don't even know if they can be properly laid to rest.

This stone-built corridor was really long; Qi Zhiheng and Yang Yitian walked through it for two hours.

Yang Yitian complained, "At this rate of walking, we should have already left Liuxi Town by now, right?"

"I sensed some spatial fluctuations. I'm afraid we've been isolated from the outside world for a long time." Qi Zhiheng had to interrupt his naive fantasy.

"Ah! Can we still go back?" Yang Yitian frowned.

Qi Zhiheng shook his head and said, "Who knows? Let's just take it one step at a time."

After walking for another two hours, the two finally stopped to rest.

Qi Zhiheng stopped because he guessed that if he continued walking down this corridor, it would probably never end. He was not naive enough to think that he could find a way back by going back.

Qi Zhiheng nudged Yang Yitian's arm and asked, "Do you see any formations here?"

Yang Yitian glanced around privately and said, "I don't feel anything. It's all bare here, there's nothing there." He then took out his food for dinner. It should be around this time outside.

Seeing that he was eating with relish, Qi Zhiheng decided to eat some himself, since he needed to be well-fed to have the energy to work.

"Do you think we could find a room if we chisel open the wall?" Qi Zhiheng's thoughts were on the wall.

Yang Yitian shook his head and said, "I don't know. There's no formation here, so I can't guess." Of course, he wouldn't say that his skills might not be good enough to detect the formation!

After enjoying dinner, the two decided to continue their journey. He took out a dagger and used his spiritual energy to stab it hard against the wall. However, it only left a shallow mark on the hard stone, causing almost no damage.

"It seems that trying to break through the wall is a bit unrealistic." Qi Zhiheng put away the dagger.
