The Emperor's heart is won, she sits on the Phoenix Throne! The Divine Physician's Eldest

"They're lying! They're the ones who killed their son!"

After Cang Yue walked over and bowed to Song Siyao, he loudly announced the results of his investigation to everyone.

When everyone heard this, there was an uproar.

Mr. and Mrs. Zhang's expressions changed drastically, their eyes filled with panic.

"And who are you? What right do you have to frame us? That's our only son, how could we possibly harm him?" Zhang's wife said angrily.

“Yes, don’t listen to his nonsense. How could we possibly harm our own son? This person must have been sent by Princess Youfeng to frame us!” Zhang Laosan added.

A murmur of discussion arose from all around.

"How is this possible? This is their own son!"

"I also think it's impossible, it must be fake, right?"

"Yes, it's definitely fake!"

"Today I have truly witnessed Princess Youfeng's shamelessness. In order to clear her name, she would even go so far as to falsely accuse someone of killing her own son!"

"As I just said, you can't see into someone's heart; you can know a person's face but not their heart."

"The one who deserves to die the most is Princess Youfeng!"

……

Song Siyao looked at the people who were cursing her, and the ones who were cursing her the most were the people that Zhang Laosan brought.

She instructed Cang Yue, "Cang Yue, tell everyone the truth you've uncovered!"

“Yes, Princess,” Cang Yue said. “This child was born to Zhang Laosan and his ex-wife. The current wife of Zhang Laosan is the one he married later.”

“The Zhang family’s child has been frail since childhood and suffers from heart disease, requiring medication year-round, which is a huge expense.”

"Zhang Laosan was addicted to gambling, and his wife was also fond of playing cards. The two of them were lazy and couldn't even support themselves, let alone their children. When the child's grandfather was alive, the old man begged to support the child. Now that the old man has passed away, the couple sees the child as a burden and poisoned him."

……

"I found the broken safety buckle at Zhang Laosan's house. Next to the safety buckle, there were also scattered insects and herbs."

Cang Yue handed over the physical evidence he found to Chen Jiang.

Chen Jiang took the herb and handed it to the coroner. He then fastened the safety buckle to the poisoned bamboo cup, and it fit perfectly, proving that the safety buckle belonged to the poisoned bamboo cup.

“Sir, this is indeed insect-derived herb, and it’s exactly the same as the poison in the bamboo cup,” the coroner said.

"Zhang Laosan, what else do you two have to say?" Chen Jiang questioned sharply.

"Innocent! Your Honor, how could I possibly kill my own child? He's the only son in the Zhang family!" Zhang Laosan pointed at Cang Yue. "It's him! He's definitely framing me!"

"To ensure the authenticity of the evidence, I wasn't the only one present at the time; there are other people who can testify."

As soon as Cang Yue finished speaking, a constable stepped forward.

“We can testify that we were there when he found the safety buckle and the herb.”

The yamen runners were sent to the Zhang family at Chen Jiang's behest.

Chen Jiang shared the same thought as Song Siyao. After receiving Hong Shao's report to the authorities, he immediately ordered the yamen runners to go to the Zhang family, fearing that the scene would be disturbed.

When the constables arrived, Cang Yue was inspecting the scene.

Seeing this, Zhang Laosan started acting crazy, shouting, "You! You're all in cahoots! You officials are protecting each other and shielding the murderer!"

"Zhang Laosan, even tigers don't eat their cubs. Now that things have come to this, do you know your crime?!" Song Siyao demanded.

"We didn't kill him! You killed him! You're the murderer!" Zhang Laosan vehemently denied it.

"Then I'll make you admit defeat today!" Song Siyao's expression was cold and stern. "Insect grass has a unique characteristic: once it gets on you, even if you wash it with water, it won't completely disappear in a short time. Insect grass is colorless and odorless, but it will turn red when it comes into contact with cabbage."

Song Siyao poured clean water into the poisoned bamboo cup, then put in a small piece of cabbage. Instantly, the originally clear water turned red.

Next, she had the coroner put his hands into clean water, then added cabbage to the water, and the water turned red as well.

When Zhang Laosan and his wife saw this, they were already terrified.

"Hold them back! Make them put their hands in the water!" Song Siyao ordered.
