"Oh, tell me, what's the matter, Lord Yunzhong?" Zu An turned around and asked.

"You have to promise to let me go first." Seeing the other party turn around, Chi Tu immediately realized that the other party was interested in his bargaining chip.

Zu An did not budge, and sneered: "What kind of person is the Duke of Yunzhong? You are just a heretical cultivator who can't even openly walk on the street. How could you possibly have anything to do with him? Xiaoqian, just send him to the authorities."

Sang Qian immediately understood: "Okay."

As she spoke, she made a gesture to lift him up and lead him outside.

Chi Tu became anxious: "I really know. On my way to the capital, I met a man who was seriously injured and on the verge of death. I learned from him that he was a confidant of the Duke of Yunzhong. He came to the capital to file a complaint with the emperor, but he was ambushed and killed halfway to silence him."

Hearing this, Zu'an was already seven or eight parts convinced: "Where is the guard?"

"He was too badly injured and is already dead." Chi Tu's expression was somewhat unnatural.

"I'm afraid you've refined his soul," Zu'an sneered.

Chi Tu hurriedly explained, "Those who cultivate our lineage do indeed need the souls of living people. Since that guard was already fatally wounded and beyond saving, I was just helping him to be freed as soon as possible. In doing so, I also learned a huge secret from his soul."

Sang Qian and Zheng Dan both felt a chill in their hearts, thinking that dying at the hands of these people would mean their souls would be enslaved by them, which would truly be worse than death.

"Tell me, what exactly is that secret? If it's substantial enough, I'll spare your life," Zuan said calmly.

"No, unless you swear an oath, otherwise if I tell you and you go back on your word, there's nothing I can do." With his life at stake, Chi Tu had no choice but to stand firm.

Zu An fell silent. Sang Qian and Zheng Dan, who were standing nearby, hurriedly advised him not to make an oath, since this was no joke.

However, Zu'an had his own plans: "Alright, I, Zhao Zhi, hereby swear that as long as the secret you tell is indeed valuable, I will spare your life; otherwise, I, Zhao Zhi, will be struck down by heaven and earth."

Sang Qian and Zheng Dan originally wanted to persuade him further, but when they heard his vow, their eyes widened immediately.

Zheng Dan smiled, while Sang Qian secretly spat, thinking, "She really is a bad apple."

Chi Tu was startled: "So you are the Crown Prince of Qi!"

The name of the King of Qi resounded throughout the land, so the name of his heir was naturally no secret.

Zu An said coldly, "What, is there anyone else who dares to impersonate this young master?"

"No, no, that's not what I meant," Chi Tu hurriedly said with a smile, thinking to himself that it was no wonder he was so powerful at such a young age. He had been nurtured from childhood by the vast resources of the Qi Prince's Mansion, which was far beyond what a rogue cultivator like himself could compare to.

Moreover, what man, besides the Prince of Qi, could have such great charm to have two such beautiful women willingly serving him?

Seeing that he had made such a vicious oath, Chi Tu no longer doubted him and whispered, "The guard came to the capital to report that the Duke of Yunzhong was not missing back then, but was murdered."

"By whom?" Zu'an asked hurriedly.

Chi Tu hesitated for a moment, but still answered, "He was killed by his own younger brother, Jian Taiding."

Zuan was shocked. Although everyone suspected that the disappearance of the Duke of Yunzhong was suspicious, no one expected such a bloody fratricidal conflict.

If this matter gets out, it will definitely cause a huge uproar, so he dares not be careless: "Do you have any evidence?"

"The guard seemed to be carrying some kind of evidence, but the assassin took it away," Chi Tu replied.

Zuan inquired about some more details, but unfortunately, he had refined the guard's soul, causing the guard to lose his memory. Much of the information was just fragments, and there was nothing more useful.

"Can I go now?" Chi Tu looked at him hopefully.

Zu An ignored him completely and instead said to Sang Qian, "Take him back to the Sang residence and lock him up. Don't send him to the authorities yet."

Chi Tu's expression changed drastically: "Zhao Zhi, how dare you go back on your word! Aren't you afraid of divine retribution?!"

Zu'an laughed and said, "What does Zhao Zhi's oath have to do with me?"
