Because Mo Wuji acted in time, the cultivator's primordial spirit stopped dissipating, his vitality stopped fading, and he was pulled into the main hall by Mo Wuji.

Only a moment later, the mist outside the hall rose again.

"I'm still alive?" The cultivator looked around, muttering in disbelief, and then he realized that his situation was very bad.

Mo Wuji took out a Rank 5 Immortal Pill and put it into the cultivator's mouth, saying, "If I hadn't saved you, you would be dead already. What did you discover? Please tell us."

The cultivator finally calmed down a bit. He looked at Mo Wuji, then at the other cultivators around him. After calming his mind, he took a breath and said, "There is a golden house ahead, shining with golden light. Inside the house are all top-grade pills, magical treasures, cultivation methods..."

The cultivator only said this much when a strange smile suddenly appeared on the corner of his mouth. Mo Wuji immediately felt bad. Before Mo Wuji could act, the cultivator fell directly to the ground, with blood flowing from the corners of his eyes. Soon after, his face turned black and filled with deathly energy.

Mo Wuji raised his hand and used a flame to turn the cultivator directly into ashes, secretly thinking how powerful the poison was. He only saw the cultivator's primordial spirit and vitality dissipating, but he did not notice that the cultivator was deeply poisoned. Earlier, he quickly struck the cultivator with his palm to stabilize the cultivator's primordial spirit, but because the Detoxification Meridian had no reaction, he did not think about poisoning.

This poison was definitely not simple; even his Detoxification Meridian did not detect it immediately.

"Big Brother Mo, what happened?" Zuo Yixian immediately came up to ask, and the others followed.

Mo Wuji said solemnly, "Everyone, according to what this person just said, there should be a golden house ahead, and there are many good things in the golden house. I guess this golden house is not to be entered. Once you go in, you will become like him. Moreover, there is a deadly poison in this golden house. If you encounter someone who comes out of the golden house and is poisoned, don't touch them."

"Are we going to leave now?" another cultivator asked.

Mo Wuji nodded. "This is not a place to stay for long. We must leave. Everyone, try to stay close together. If we encounter any problems, we can take care of each other."

"When are we leaving?" a cultivator in the crowd asked.

"Don't rush. We'll talk after this wave of mist recedes." After Mo Wuji finished speaking, he turned his gaze to Zuo Yixian. "Yixian, you call me Big Brother, so I won't be polite with you."

Zuo Yixian has cultivated to this point and is a Star-Rank genius. Since Mo Wuji said so, how could he not know that Mo Wuji needed his help? He immediately said, "Big Brother Mo, just tell me what to do. As long as I can do it."

Mo Wuji smiled and said, "It's not that serious, don't worry. I just want to ask you a few questions. Your status in Yongying Immortal Domain should be pretty good, right?"

Zuo Yixian replied, "Yes, I am the Young City Lord of Penghai Immortal City. Penghai Immortal City is second only to Yongying Immortal City, where the Heavenly Emperor is located, so my status is somewhat significant."

"Good. I'll ask you a few questions. The first question: do you know about Immortal Lattice Stones?" Mo Wuji didn't rush to ask the second question. He could ask Zuo Yixian this question because his status was different from before.

After asking this question, Mo Wuji said to the other cultivators, "Everyone, guard the entrance of the main hall's formation first. I'll take everyone away from here as soon as I'm done."

Everyone was sensible and did not continue to eavesdrop, but retreated to the entrance of the main hall.

Mo Wuji saw that Murong Xiangyu and another round-faced cultivator had not left. Just as he was about to ask, he heard the round-faced cultivator clasp his fists and say, "Big Brother Mo, I am Cang Heng, a disciple of Qingxu Dao. I also know something about Immortal Lattice Stones, so I stayed to answer Big Brother Mo's questions."

Zuo Yixian quickly explained, "Big Brother Mo, Qingxu Dao, where Cang Heng is, is one of the largest immortal sects in Yongying Immortal Domain. Senior Sister Nong Xiaoyu of Qingxu Dao is already at the mid-stage of Grand Yi Immortal. She's an eight-star genius, and one of the top geniuses even in our Yongying Immortal Domain. Moreover, Qingxu Dao's Dao Gate is still in Yongying Immortal City, so Cang Heng knows even more about Immortal Lattice Stones than I do."

Murong Xiangyu also quickly said, "I also know something about Immortal Lattice Stones, so I stayed."

Mo Wuji didn't object and continued, "Since that's the case, then everyone can explain about Immortal Lattice Stones."

Cang Heng took the initiative and said, "Let me explain. All cultivators who have cultivated to Heavenly Immortal are clear about it. Without an Immortal Lattice, it is impossible to advance further from the Heavenly Immortal realm. And the Immortal Lattice is the path of immortality for a person. Only by condensing an Immortal Lattice will your future path have direction and goals. In other words, you will have a true foundation for immortality. And Immortal Lattice Stones are the most basic means for many Heavenly Immortals to condense their Immortal Lattice. Immortal Lattice Stones contain a kind of Heavenly Dao Dao rhythm. As long as you condense an Immortal Lattice with an Immortal Lattice Stone, it will be easy to comprehend the natural path of immortality."

"But Immortal Lattice Stones are very rare. Most of the Immortal Lattice Stones in Yongying Immortal Domain come from various Semi-Immortal Domains. I heard before that several Semi-Immortal Domains collapsed and turned into Immortal Chasms, so Immortal Lattice Stones are even scarcer."

"Then did you also use Immortal Lattice Stones to condense your Immortal Lattices?" Mo Wuji asked again.

Zuo Yixian interjected, "No, cultivators with high aptitude and status generally don't use Immortal Lattice Stones to condense their Immortal Lattices."

"Why?" Mo Wuji blurted out.

Zuo Yixian explained, "Because the origin of Immortal Lattice Stones is very mysterious. It is rumored that they are condensed from the Dao thoughts of ancient fallen gods. Once you use Immortal Lattice Stones to condense your Immortal Lattice, you will be branded with someone else's Dao thoughts. It's okay when your cultivation is low, but once your cultivation is high, you will be affected by other people's Dao thoughts, and it will be difficult to make any further progress."

After a pause, Zuo Yixian continued, "So we condense our Immortal Lattices by comprehending the Heavenly Dao rules of nature ourselves, and then use top-grade cultivation resources to condense our Immortal Lattices. Of course, this method of condensing Immortal Lattices is very difficult. First of all, the person condensing the Immortal Lattice needs to have a certain aptitude and comprehension. Secondly, the person condensing the Immortal Lattice needs to have a certain amount of wealth. These are indispensable."

Mo Wuji's heart sank. Several of his friends had condensed their Immortal Lattices through Immortal Lattice Stones. It seemed that he would have to ask them for help in the future and definitely not let Immortal Lattice Stones become an obstacle to their path.

"Second question: do you know about Yongying Prison?" Mo Wuji did not continue to ask about Immortal Lattice Stones, but asked about Yongying Prison. He had been wanting to ask someone about this question, but he had never known anyone powerful in Yongying Immortal Domain.

Almost at the same time that Mo Wuji asked this question, Zuo Yixian and Cang Heng's expressions changed, and even Murong Xiangyu's expression was a little strange.

Mo Wuji raised his hand and set up a soundproof restriction, saying in a deep voice, "If you find it difficult to answer this question, then pretend you didn't hear it. If you treat me as a friend, then please tell me."

Mo Wuji judged others by himself. If he regarded Zuo Yixian and the others as friends, and it was his turn to answer this question, he would answer without hesitation. If Zuo Yixian was unwilling to answer, he would not continue to ask. At the same time, he would not regard Zuo Yixian as a true friend. After leaving here, everyone would go their separate ways.

He didn't have so many tricks when making friends. He would definitely help if he could. Friends who were hesitant and only wanted benefits, please stay away from him.

Cang Heng suddenly said, "I'll answer this. I know more details than Brother Zuo and Senior Sister Murong. In fact, the decline of Yongying Immortal Domain, apart from that war, is related to the lack of more backup geniuses."

Cang Heng's qualifications were greater than Murong Xiangyu's. Because of Mo Wuji's relationship, he changed his address to Senior Sister Murong.

"Since that's the case, then we should protect those geniuses who ascend from the cultivation world. Why do you do such a thing with the prison?" Mo Wuji frowned.

Cang Heng sighed and said, "The problem lies here. All the geniuses who ascend to Yongying Immortal Domain are, without exception, disciples of those large sects in the cultivation world. They cultivate in Yongying Immortal Domain, obtain cultivation resources, and after reaching a certain level, they directly leave Yongying Immortal Domain to find their own sects. And those large sects basically have no presence in Yongying Immortal Domain."

"These genius disciples have amazing aptitudes and their cultivation progress is extremely fast. After they find their sects, their strength will increase even more rapidly. And every few years, there will be resource争夺 wars in various immortal domains. For example, this Shattered Realm will also have wars in the future. The native genius cultivators and some potential disciples of Yongying Immortal Domain basically die in these wars to those genius powerhouses who ascended from the cultivation world."

"These ascended cultivators are ruthless and decisive in killing, even more terrifying than the native geniuses. Thousands of years ago, there was an eight-star genius named Huang Sha. He ascended to Yongying Immortal Domain. But his sect was the Great Sword Dao of Lingtian Immortal Domain. He cultivated to Mysterious Immortal in Yongying Immortal Domain and went to Luoling Immortal Domain to enter the Great Sword Dao. In a secret realm, he alone killed 317 genius disciples of Yongying Immortal Domain, severely damaging Yongying Immortal Domain."

"As time passed, Yongying Immortal Domain became weaker and weaker. If this continues, it will probably be swallowed by other immortal domains soon. Therefore, the Yongying Heavenly Emperor and the sect leaders of many top sects discussed building Ascending Colored Clouds in the cultivation world, so that all ascending cultivators would enter the Semi-Immortal Domain. In fact, the Semi-Immortal Domain has existed for many years. Before, the cultivators who entered the Semi-Immortal Domain had the opportunity to enter Yongying Immortal Domain, but later they were imprisoned and not allowed to enter Yongying Immortal Domain. Once they encounter geniuses above the four-star level, they are directly taken away and sent to Yongying Prison."

"Is it true that making a blood oath in Yongying Prison will lead to release?" Mo Wuji gradually understood.

Cang Heng sighed, "That's right. Only by making a blood oath in Yongying Prison, vowing to fight for Yongying Immortal Domain in the future, or even go to their own sect to be an undercover agent for Yongying Immortal Domain, will they be released and fight for Yongying Immortal Domain for the rest of their lives. In fact, which Star-Rank genius isn't arrogant? Making such a blood oath is no less than cutting off their path to immortality. It's not that they must do their best for their sect, but they are unwilling to cut off their path to immortality."

Mo Wuji was still somewhat puzzled and asked, "Even if Yongying Immortal Domain keeps the prison a secret, the Semi-Immortal Domain shouldn't be a secret. Why haven't other immortal domains interfered?"
