Jiang Si's words immediately attracted the attention of everyone present.

Zhen Shicheng couldn't wait to ask, "How does Miss Jiang prove it?"

"Lord Zhen, could you please come with me to Juxia Lake?" Jiang Si asked.

Zhen Shicheng nodded: "Of course you can."

He had originally planned to go to the scene and take a closer look after asking questions.

A group of people returned to the shore of Juxia Lake in a mighty stream.

Jiang Si pointed and said, "Master Zhen, look, although the footsteps in this area are messy, one line of footprints is very obvious."

Zhen Shicheng looked carefully, pointed to a line of wide footprints by the lake and asked, "Miss Jiang, are you talking about this line of footprints?"

Jiang Si nodded: "Yes, these footprints were left by my second cousin. If you don't believe me, you can take the shoes my second cousin is wearing now for comparison."

Su Qingyi had a large body and surprisingly large feet. Once, when Jiang Si stayed at the mansion for a short time, he overheard a maid complain that the second young master's shoes were difficult to make, and he was deeply impressed.

When everyone arrived at the scene just now, Jiang Si knew that there would be trouble, so he was secretly looking for clues and soon found this line of footprints.

"Bring the shoes worn by the second young master Su for comparison." Zhen Shicheng ordered his subordinates.

Soon, the subordinate brought a shoe and compared it carefully before saying, "Sir, these footprints were definitely left by the owner of the shoe."

Jiang Si walked forward a few steps and stood by the Juxia Lake: "The last pair of footprints are here, with the toes of the shoes facing the lake. It can be seen that my second cousin was facing the direction of Juxia Lake before he fell into the water. If my second cousin was pushed into the water, then the murderer must have been standing behind him. Your Excellency, do you think what I said makes sense?"

Zhen Shicheng nodded: "Miss Jiang's words make sense, but apart from the footprints of the second son of the Su family, the other footprints are too numerous and messy. It is almost impossible to find the murderer's footprints from these footprints."

Zhen Shicheng said this with a sigh in his heart.

Just like many crime scenes, people’s ignorance often destroys many important clues, which makes it very difficult to solve a case that would otherwise be easy to investigate. However, we cannot blame the victims for this.

Jiang Si stared at the chaotic footprints on the ground, feeling heavy in his heart.

Among these footprints, there must be one that was left by the murderer, but unfortunately, with the arrival of rescuers and onlookers, it is impossible to tell which one is which.

Jiang Si sighed softly, "Your Excellency misunderstood. When I mentioned the footprints, I certainly didn't expect to find the murderer by this, but to let everyone know where the murderer was standing at the time. If there really is a murderer, he should be standing here. Do you agree?"

Everyone nodded.

Jiang Si lifted the hem of her skirt and said, "My second cousin is big. If he falls into the water, it will definitely cause a lot of splashes, and the murderer's clothes will inevitably get wet."

"So what? The sun is so strong, even if it was wet it would have dried up after such a long time." Yu Shi retorted.

Jiang Si looked at Youshi: "It was still early when I returned to the stage. People who saw me can prove that my clothes were clean. Besides, could it be that my aunt-in-law couldn't recognize the material of my skirt?"

Yu looked carefully and her face changed slightly.

The green skirt that Jiang Si was wearing was bright in color and was made of a kind of expensive material called "Biyingsha". This material was made into summer clothes, which was cool and sweat-free, and was extremely comfortable. Many noble ladies liked to wear it, but there was one disadvantage: even a few drops of water would smudge it, like oil stains. But Jiang Si's green skirt was clean and spotless, without a single spot.

Just as Jiang Si said, no matter how careful the murderer was, it was impossible for Su Qingyi to be pushed into the water without getting any splashes on her body, and she undoubtedly proved her innocence with a green dress.

Jiang Si stopped looking at Youshi's ugly face and smiled at Zhen Shicheng: "I'm sorry, I can only prove my innocence. As for finding the real murderer, I'll have to trouble Master Zhen."

Zhen Shicheng looked at Jiang Si with admiration in his eyes: "Miss Jiang did a great job."

Jiang Si bent his knees slightly and stepped aside.

Jiang Zhan gently pulled Jiang Si and gave her a thumbs up.

Jiang Sihui smiled, but soon stopped smiling.

Perhaps it was because Su Qingyi died of illness very quickly in her previous life, and she had actually accepted this matter subconsciously. So when it happened in front of her, although she felt heavy-hearted, she did not feel the kind of uncontrollable despair that she felt when facing the death of Yongchang Bo and his wife.

"So, the murderer may have changed his clothes?" Yu Shi suddenly asked.

Zhen Shicheng nodded: "This possibility cannot be ruled out."

Yu slowly moved her gaze, finally landing on the second wife, Xu.

Everyone followed Yu's gaze, and several maids and servants' faces changed instantly.

They both recalled that the Second Wife, Mrs. Xu, had worn a royal blue silk jacket with a persimmon calyx pattern at the birthday banquet, but had left the theater in the middle of the show and was now wearing a lilac jacket with brocade patterns.

"Why did my sister-in-law change her clothes?" Yu took a step forward and stared at Xu fiercely.

When she was listening to the opera on the stage, she accidentally saw Xu hurriedly leaving the stage, and she was suspicious, but she didn't think much about it. Now that she thought about it, if Xu had attacked the second son, the timing would have been perfect.

Xu glanced at You indifferently and asked, "Do I need to report to my sister-in-law even if I change my clothes?"

"I don't care how many clothes you change at ordinary times, but now that Yi'er is dead, you are suspicious if you change clothes!" Yu Shi looked excited, "Master Zhen, she left in the middle of the play before, and the time is exactly when my second son was killed. This can't be just a coincidence!"

"Madam, please be patient," Zhen Shicheng soothed.

Mrs. Xu said calmly, "Sister-in-law, don't splash dirty water on others at will. I left the theater halfway through the show because my maid came to report that Bao'er had woken up. I went back to give Bao'er medicine, and the medicine was spilled on my clothes, so of course I had to change my clothes. My maid can prove this."

When Mrs. Xu mentioned Su Qingbao, Mrs. You became even more excited: "Don't try to make excuses. You must have killed Yi'er in order to avenge Bao'er!"

"Shut up!" Elder Su shouted, his face gloomy, "Aren't you ashamed to talk nonsense in front of so many people?"

"I'm not talking nonsense! Even if you don't want your family's shame to spread, you can't let Yi'er die with regrets!"

Zhen Shicheng coughed and said, "Prince Su, I want to hear why the Crown Prince's wife said so."

The blow of losing her son and the frustration of her plot made it difficult for Youshi to control her emotions. She told the truth without hesitation: "Yier is mentally retarded and likes to play with others. Two days ago, when he was playing hide-and-seek with Baoger, he accidentally pushed him off the rockery. Baoger suffered a head injury and was unconscious for a long time. Xu must have been holding a grudge against Yier!"

When Mrs. Xu heard Mrs. You mention her son, her eyes turned red and she sneered, "Sister-in-law is wrong. It is precisely because I was heartbroken after Bao Ge'er was injured that I would never harm other people's children. As a mother, I can't do such a thing!"

At this time, the young man's cold voice came: "I found something interesting."
