Jiang Sidu's determined expression made Su Qingxue's heart beat fast. Under the gaze of everyone, she bit her lip unconsciously.

"My second cousin doesn't dare to swear, so can I understand that you are feeling guilty?" Jiang Si asked bluntly.

"Who feels guilty?" Su Qingxue retorted sharply.

Jiang Si smiled: "Then, second cousin, do you dare to swear?"

Su Qingxue calmed down and said forcefully, "I have already sworn, why do I have to swear again? There are so many people here, but my cousin is targeting me. Is it because I am just an insignificant concubine's daughter? My mother is so tolerant and doesn't make things difficult for me, a concubine's daughter. What right does my cousin have to do this?"

Su Qingxue's words were spoken with loud voices and tears streaming down her face. She looked extremely aggrieved, which made many people present feel that Jiang Si's behavior was a bit too much.

Jiang Siren didn't care about those looks, her delicate eyebrows revealed some surprise: "Now we need to find the murderer who killed my second cousin, why did my second cousin bring up the legitimate daughter and concubine's daughter? I am asking you alone among so many people here, isn't it because only your handkerchief appeared in Chaoyang Pavilion? My second cousin doesn't think that you can completely clear yourself of suspicion by saying that the handkerchief was blown there by the wind by chance, right?"

"It was just a coincidence. My third sister can testify to that!"

Su Qingyu saw Su Qingxue pushing her out. Although she felt annoyed, she nodded and said, "Yes, my second sister and I were passing by the lake. When we saw people floating in the lake, we were very scared and ran away in a hurry. The handkerchief must have been dropped by accident at that time."

After hearing what Su Qingyu said, Su Qingxue's tense body relaxed.

Jiang Si sighed: "The third cousin can only prove that she was with the second cousin when she passed by Juxia Lake, so what about before that?"

"Before?" Su Qingyu was stunned.

Seeing Su Qingyu's reaction, Jiang Si had an idea in his mind: "Yes, have the third cousin and the second cousin always been together before? Have they never been separated?"

Su Qingyu was stumped by the question and subconsciously looked at Su Qingxue.

She remembered that there was a period of time when she seemed not to have seen her second sister. At that time, a cousin happened to come to chat with her, but she didn't pay much attention.

Su Qingxue's lips turned a little paler.

"Third cousin, do you think this question is difficult to answer?" Jiang Si asked calmly.

Mr. Su frowned and looked at Su Qingyu with a serious expression.

Su Qingyu felt a tremendous pressure coming upon her, making her feel overwhelmed.

Jiang Si retracted his gaze and looked at Zhen Shicheng: "Master Zhen, the third cousin avoided answering such a simple question. I think the third cousin is more suspicious than the second cousin——"

"No!" Su Qingyu suddenly interrupted Jiang Si's words, her face turning pale.

If she kills her second brother, she will have to pay with her life. How could she get into such trouble!

Su Qingyu was panicked and scared. She didn't care about anything else and said hurriedly, "My second sister and I were not together all the time. I was chatting with others for a while and didn't pay attention to where my second sister went. Later, my second sister sat back next to me, and her clothes got dirty soon after. I accompanied her back to change clothes..."

Speaking of this, Su Qingyu felt a little resentful towards Su Qingxue.

If Su Qingxue hadn't pulled her back to change clothes, how could she have seen her second brother drowning in the lake?

At that time, they were so scared that they ran away without even looking at who was in the lake. When they heard that it was their second brother, they were even more scared. If their father and stepmother knew that they had run into their second brother but did not save him in time, they would definitely be angry and punished.

That's why she didn't dare to mention it before.

Jiang Si got the answer he wanted and curled his lips to the pale Su Qingxue: "Then can the second cousin tell me what you did during the time when you were not with the third cousin?"

Su Qingxue felt that the corners of the other person's lips were more frightening than a vicious demon. She tried her best to control her panic and said, "I'm just strolling around the garden. There are so many people strolling around like me. Is this not okay?"

Jiang Si spread his hands: "But those people's handkerchiefs did not appear in Chaoyang Pavilion."

"Pfft." A light laugh was heard.

Jiang Si glanced at Yu Jin, then calmly looked away.

Yu Jin raised the corners of his lips awkwardly, feeling a little disappointed.

She is still so cold to him, what a cruel girl.

Jiang Si suddenly stepped forward and spoke word by word, "Second cousin, you were in Chaoyang Pavilion during that time, right? You were the one playing with my second cousin in the pavilion! I passed by Juxia Lake, and my second cousin rushed out to play with me. I left in a hurry to find my eldest sister, so you two were the only ones left there!"

Her tone was so certain that most people subconsciously believed her.

Jiang Si smiled coldly: "After I left, you pushed your second cousin into the lake for some reason, and then ran back to find your third cousin. Because you and your third cousin are inseparable, when you appeared together after the incident, others would subconsciously think that you were together all the time, which provided you with evidence of your absence. In fact, the handkerchief was dropped by you earlier. Second cousin, am I right?"

"No, I didn't kill my second brother. You are slandering me!" Su Qingxue retorted fiercely.

Jiang Si looked at her expressionlessly, without any emotion: "Since my second cousin said that I was slandering you, then swear as I said to prove that you have a clear conscience."

"I, I--" Su Qingxue slowly took two steps back.

Master Su became suspicious of Su Qingxue's reaction and asked in a deep voice, "Xue'er, does your second brother's death have anything to do with you?"

"It wasn't me who harmed my second brother. It wasn't me!" Su Qingxue shook her head violently, looking like she was about to collapse.

More and more strange looks fell on her, making it almost impossible for her to bear the burden.

In her panic, Su Qingxue met Youshi's cold gaze, and her back instantly felt cold.

She couldn't let her stepmother suspect her, otherwise even if she survived today, she would still be dead!

As for her understanding of Youshi, Su Qingxue believed that she knew her better than her elder sister Su Qingshuang.

She was suspected but her stepmother said nothing, it was because her stepmother was unwilling to explain her affairs that were revealed, not because she was tolerant of her. She had to make her stepmother believe that she left immediately to find her third sister after seeing her second brother entangled with Jiang Si, otherwise she would be in trouble.

"Okay, I swear--" Su Qingxue saw that there was no way to retreat, and raised her hand tremblingly.

Jiang Si shook his head at this time: "You can't swear like this. If you have a clear conscience, swear in front of me."

Su Qingxue's face turned pale instantly and she screamed, "Jiang Si, don't push me too far!"

Jiang Siyi's expression was calm: "Second cousin, you are overthinking. I just don't want my second cousin to die with regrets."

Mr. Su sighed and said, "Xue'er, just swear an oath."

Su Qingxue looked at Master Su with a pale face, her whole body shaking violently.

At this time, a man rushed out and said, "Don't make things difficult for the second girl. I'm the one who killed her!"
