Song Yi walked over and knelt down next to Mrs. Song: "It is my fault, I concealed the truth. But I really don't know why Miss Xie had an accident."

Gu Xin turned to look at Xie Jun, who was just about to curse. When he saw Gu Xin looking over, he obediently shut up, but his eyes were fixed on Song Yi as if he wanted to devour him.

Gu Xin asked, "Since you know Miss Xie, did you see her on the seventh day of the month?"

Song Yi was silent for a moment, then said, "I've met you."

Seeing that he was silent, Gu Xin frowned and said coldly, "Tell me the truth about what happened that day!"

Mrs. Song also tugged at Song Yi's sleeve.

Song Yi said, "After school that day, I was preparing to go home as usual. As I passed the academy gate, I saw Miss Xie walking away with another girl. That girl was not Manzhu, who was Miss Xie's maid. At first, I found it a bit strange because Miss Xie always appeared with Manzhu. The girl's clothes were not those of a maid in the Xie family; they looked like those of a girl from an ordinary family. I was not familiar with Miss Xie, so although I found it strange, I did not go up to ask. I went home. I have already explained what happened last night."

Gu Xin was somewhat angry: "Since you knew, why didn't you say so last night? What good would it do to tell the truth if you didn't do it? Song Yi, you were born a student of the Great Zhou Dynasty and are preparing for the imperial examinations, yet you don't trust the court. Do you know that your concealment might cause us to miss some clues? Do you know that once your concealment is discovered, you will be the prime suspect?"

Song Yi bowed his head: "This student knows his mistake, please punish me, Your Highness!"

Gu Xin: "Chen Xiaoli, take Song Yi back to the yamen! He is not to be released until this case is closed!"

Mrs. Song was terrified: "Princess, no! Yi'er didn't kill anyone, he's telling the truth. Yi'er still has to take the imperial examinations, he can't go to jail! Please, Princess, have mercy! Please, Princess, have mercy!"

Mrs. Song kept kowtowing, and Gu Xin immediately had someone help her up.

At this moment, Ye Cuiru also stepped forward to help persuade them.

Gu Xin sneered: "Are you trying to teach me how to do things? If you keep causing trouble, I'll take you all away!"

Mrs. Song fainted again, and Ye Cuiru was pulled aside by Mrs. Zhu.

Gu Xin glanced at Ye Cuiru and Zhu Shi. Zhu Shi lowered her head and apologized, while Ye Cuiru lowered her head and hid her hands in her sleeves. Gu Xin could see that her fists were clenched very tightly.

Song Yi asked Gu Xin for some time to settle his mother, and Gu Xin agreed. She also had a constable accompany Song Yi into the house, just in case the mother and son said something in private!

As Song Yi carried Mrs. Song back to their room, Gu Xin looked at Xie Jun and said, "Go back! I'll take charge of this case, and I'll find the real culprit and give Miss Xie an explanation."

Xie Jun pursed his lips, then clasped his hands in thanks before asking, "Princess, I would like to ask, is Song Yi really unrelated to my sister's death?"

Gu Xin looked him up and down and said, "Whether it's related or not is not up to me to decide. Without evidence, everyone who knows Miss Xie might be involved in this matter."

As Gu Xin spoke, she glanced at Zhu Shi and Ye Cuiru, and then continued, "Of course, it's also possible that none of them are related. Everything depends on the evidence."

Xie Jun was silent for a moment, then asked, "What about Manzhu? Does the princess think Manzhu is a suspect?"

Gu Xin raised an eyebrow, surprised that this playboy actually had some brains: "How do you know?"
