Cheng Shaoyuan asked curiously from the side.

"Yes, it must be Madam Gu. This Xiuniang must have been to the Gu Mansion."

After Gu Yunru finished speaking, she suddenly thought of something, took off the gold ring, rushed to Cheng Mansion first, and placed the gold ring in front of Gu Junyue. When Gu Junyue saw this, tears fell like unstoppable raindrops.

"This is from mom, this is mom's ring..." Gu Junyue burst into tears while holding the ring. Cheng Shaoyuan patted her shoulder gently to comfort her, and Gu Junyue leaned into her arms.

"Where did you find it?" Gu Junyue looked at the two with tears in her eyes. Gu Yunru frowned at the gold ring and said, "We found it on the hand of a showgirl. Do you have any impression of this showgirl?"

"Xiuniang...seems like she was working in the mansion before, and was kicked out for stealing." Gu Junyue immediately thought of this woman named Xiuniang. She was kicked out of the mansion because of her rude behavior and improper style. Unexpectedly, she actually stole his mother's gold ring. He was so angry that he gritted his teeth and cursed Xiuniang.

"She is already dead, and her body has been dismembered."

Gu Yunru reminded from the side. When Gu Junyue heard it, her face turned pale with fear and her lips trembled. She didn't dare to say anything and leaned into Cheng Shaoyuan's arms, looking as weak as a young wife who was bullied.

Cheng Shaoyuan called the maid beside him and asked her to take Gu Junyue away first.

After the people left, Gu Yunru sat aside, looked up at Cheng Shaoyuan who looked unhappy, and said, "Do you have anything to say?"

"No……"

"Well, there are still many strange things about this matter. Now we can only catch that Zhang San back."

Maybe Zhang San knows what's going on with the ring on Xiuniang's hand.

At this time, Cheng Shaoyuan's confidant came to report that Zhang San had been caught in the gambling house and was taken to the Dali Temple for interrogation. However, this man was very cunning and had not yet told the truth.

"I'll go first, you go back home first."

Cheng Shaoyuan was afraid that the next interrogation would scare her, but he didn't expect her to straighten her back and say seriously, "No, I want to go too."

"Okay." Cheng Shaoyuan always liked to go along with her, and seeing that she insisted on going with him, he agreed.

When he arrived at the Ministry of Justice, Gu Yunru saw all kinds of cruel torture instruments, including the wooden horse and iron branding. These cruel torture instruments were enough to torture a person's body, mind and spirit. However, Zhang San had been whipped and tied up, and his body was covered with bruises, but he didn't seem to say anything.

"Zhang San, you are quite stubborn."

Gu Yunru walked up to her with an expressionless face and handed the cloak to Qingxing behind him.

"I really don't know anything..." Zhao San lowered his eyes, his face was as swollen as a pig's head.

"It would be strange if you didn't know anything. Xiuniang's body has been found. What else do you have to say?"

Zhang San was strong enough to cut off Xiuniang's head. Moreover, Zhang San admitted that he had stolen things from Gu Mansion. Zhang San lost again and again in the gambling house, and he also pawned some of the gold and silver jewelry he had stolen from Gu Mansion. After investigation, it was confirmed that they were indeed the things from Gu Mansion. So this time, even if Zhang San had mouths all over his body, he could not explain himself.

"Xiuniang...Xiuniang is dead?" Zhang San looked at the two of them in shock. Gu Yunru and Cheng Shaoyuan looked at each other. Gu Yunru smiled coldly, "It's come to this point now. You still want to pretend that you know nothing. Isn't it a little too late?"

Gu Yunru stared at his expression. As Zhang San's body was covered in blood, it was difficult to tell whether his eyes revealed fear or guilt. However, from his tone, it could be heard that he really didn't know that Xiuniang was dead, and perhaps Xiuniang really had nothing to do with him.

"Zhang San, if you confess, you will be treated leniently, while if you resist, you will be treated severely. If you don't tell the truth again, you should know the consequences." Cheng Shaoyuan's tone was cold and his expression was his usual indifferent. He stared at Zhang San in front of him, as if he was still trying to find an excuse to get away with it.

"I really didn't know Xiuniang was dead. I went to Gu's house to steal some money just to pay off my debts at the gambling house."

"When did you go to the Gu Mansion?" Gu Yunru asked, grasping the key point, her gloomy eyes staring straight into his eyes.

Zhang San recalled carefully, "On that night, there were screams coming from the Gu Mansion. I hid aside and saw a woman holding a knife leaving the Gu Mansion. That woman... I didn't see what she looked like. After I saw that everyone was dead, I secretly climbed over the wall and found that no one was alive, so I went to pick up some things..."

Zhang San still had a look of fear when he said this, as if that woman had left a big shadow on him. Gu Yunru looked into his eyes and it seemed as if there were some words she hadn't told him honestly, so she directly put the dagger against his neck.

"Tell me, what are you hiding? Tell me everything, or I will be very sharp."

"Sir, I really don't know... I... Well, when I was about to leave, I found Xiuniang having an affair with a man. They were doing that kind of thing openly in front of the door of Gu's house. After seeing it, I was ready to teach that man a lesson."

After hearing this, Gu Yunru reluctantly took the knife from his neck and continued to ask, "What happened next?"

"I wanted to go up and argue with them, but I didn't dare to go forward. Later, they walked away. I don't know where Xiuniang and that man went."

"Then why did Xiuniang's body appear in your house?"

"Sir, God has eyes. I often hang out in gambling houses, eating and waiting to die. I haven't been back to that place for a long time."

Zhang San lowered his head and tears of grievance fell. Seeing a grown man crying out loud, Gu Yunru felt some empathy.

He and Cheng Shaoyuan walked to the door, turned around and looked at him and said, "Do you believe what Zhang San said?"

Cheng Shaoyuan thought about it and said, "I don't believe it."

"I believe what he said is true. The murderer may not be Zhang San, but Zhang San must know something that he hasn't confessed yet. We must investigate the man who was with Xiuniang that night."

If the murderer was really Zhang San, he would definitely take off the gold ring on Xiuniang's hand and pawn it.

He has owed a lot of debts recently. I think the people in the casino know best. Where has he been these days? A butcher has a bad business and his wife is not devoted to him. It is inevitable that he will have a different mind. This is also possible. However, he has been so short of money recently, but he did not take the ring from Xiuniang's hand. This is enough to prove his innocence.

After listening to Gu Yunru's analysis, Cheng Shaoyuan felt that there was some truth in it, but he also felt that there were some shortcomings.
