Gu Yun still had a question in his mind. He lowered his voice and asked Liu Ziqi, "What do you think of Yu Qizhe? How did he... know that Cheng Ying was the person behind the scenes?"

"He has an extraordinary mind. Given time, he will be a rare figure." Liu Ziqi said pertinently, "It is not difficult to guess that it is Cheng Ying, especially for a young man like Yu Qizhe who is just starting out. He is young and fearless, unlike the court officials who are immersed in the court and have too many interests involved. Instead, he can destroy the rotten sore behind in one fell swoop."

Although Yu Qizhe's plan was reckless and simple, it just happened to work.

"Hurry up, in case Cheng Ying gets the news and sends someone to disrupt the situation." Liu Ziqi said, "You go to the palace to see the emperor, and Qin Huaiyuan will be taken back to Wucheng Bingmasi first. Have capable people guard him, and there must be no mistakes."

Gu Yun ordered the soldiers to speed up, but they were still blocked outside the city gate.

A group of men in black started to rob people and steal silver without any explanation. It goes without saying who sent them.

Gu Yun brought soldiers to protect Qin Huaiyuan and the dirty silver, and fought with the men in black. Liu Ziqi took Gu Yun's token, called the guards at the city gate, and asked them to transfer guards from the city defense.

The dozen or so men in black were all very skilled in martial arts, and were far beyond the ability of the soldiers that Gu Yun transferred from the Wucheng Bingmasi to resist. Although Gu Yun was holding them back, some of them still approached Qin Huaiyuan.

Gu Yun injured a man in black with his sword, then leaped to Qin Huaiyuan's side and used his sword to force back the man in black who wanted to take Qin Huaiyuan away.

After throwing Qin Huaiyuan to the care of two soldiers, Gu Yun started fighting with the men in black again. The city gate guards, who were urgently dispatched, rushed over and surrounded the group of men in black.

Seeing this, the leading man in black looked in the direction of Qin Huaiyuan, took out a hairpin from his arms and threw it out. Gu Yun raised his sword to block it, and the hairpin fell to the ground.

The group of men in black took advantage of this moment and threw several gunpowder bombs on the ground. A thick fog suddenly rose up. When the smoke cleared, the group of men in black were gone.

"Do you want to chase them?" a soldier asked.

Gu Yun shook his head and said, "Go into the city."

He squatted down and picked up a very ordinary hairpin on the ground. He didn't quite understand why those men in black threw down such a hairpin.

Qin Huaiyuan, who was being escorted by the soldiers, glanced at the hairpin on the ground and closed his eyes. No one knew better than her that this hairpin was the ornament that his wife wore on her head all year round.

Qin Huaiyuan was also very clear about the purpose of those people throwing the hairpin down. It was just to silence him and let him know what to say and what not to say.

If he was smart, the whole family could still have a chance to survive. But if he confessed something he shouldn't have said, the Qin family would have no chance to survive.

Qin Huaiyuan could even guess that those men in black were not here to rescue him, but to kill him to silence him.

In fact, there was no need to do this. The moment Qin Huaiyuan was exposed and arrested, he had thought about his own fate.

It is said that if the king wants his subject to die, the subject must die.

No matter how stupid he was, he would never drag Cheng Ying into this.

Once in the city, there were no more disturbances.

Qin Huaiyuan was escorted to the Wucheng Bingmasi, where more than a dozen people watched him without blinking an eye.

Although it was not yet dawn, Gu Yun did not stop and went straight into the palace.

When the sun rose, the city was as bustling as ever. The breakfast shops on the street were busy and steam was rising from the steamed bun shops. Yu Qizhe, who had been awake all night with a candle, came to the street next to Kanjing Hutong and ordered a bowl of hot porridge and two steamed buns, which he ate calmly.

After eating, Yu Qizhe went to the clothing store, bought a set of clothes according to Lu Jin's size, and asked Liuzi to drive to the gate of Dali Temple to pick him up.
