Hua Yuanzhao moved very quickly. While everyone was silent, she quickly snatched the dagger from the soldier's tray behind the coroner.

Everyone saw a flash before their eyes, and the mountain-like man was already kneeling beside the corpse, holding a dagger for comparison.

Hua Yuanzhao took off the silver hairpin on his head and used it as a dissecting needle. He opened the wound and took a closer look. The bloody wound was vertical and flat, and the shape of the blade was consistent with that of a dagger.

"The knife wound was indeed caused by this dagger, but it was formed after the person died or fell into a coma." Hua Yuanzhao held the dagger with both hands and made a vertical stabbing motion.

"And it must be stabbed vertically like this to cause such a straight wound." Hua Yuanzhao added.

"What nonsense are you talking about!" Hua Yuanshan scolded: "Do you really have to bring disgrace to the Prime Minister's Mansion before you stop?"

Hua Yuanzhao suddenly rushed towards Hua Yuanshan and did what she had wanted to do since last night.

She pounced on Hua Yuanshan's back and instantly strangled her neck with her arms. Hua Yuanshan was almost unable to breathe. She could only hold her arms and scream in a hoarse voice.

Amidst the shrill screams, Hua Yuanzhao stabbed Hua Yuanshan's heart with the dagger in his hand, but stopped at the critical moment.

Hua Yuanshan was so frightened that she lost all her image. She just grabbed Hua Yuanzhao's hand and tried to push the dagger away from her.

Upon seeing this, Prime Minister Hua's eyes widened with anger and he stamped his feet anxiously, "Evil girl! It's not enough that you've harmed Han Yunlan! Are you going to kill your own sister now?"

Gu Changsu was also shocked by this sudden change. He cursed with a dark face: "Hua Yuanzhao! Do you think you can escape like this?"

"What's the hurry?" Hua Yuanzhao smiled slyly, and she said calmly: "I just want to give a demonstration to my father and His Highness."

She squeezed Hua Yuanshan so hard with her arms that she could hardly breathe.

"Second sister and cousin are similar in height, so I can only ask second sister to help." Hua Yuanzhao asked threateningly: "Is second sister willing?"

"You fat pig! How dare you do this to me? My mother will not forgive you!" Hua Yuanshan was frightened and could only scream.

Hua Yuanzhao exerted force on his hands again, causing Hua Yuanshan to roll her eyes and her curses turned into hoarse voice.

"It seems that he is willing." Hua Yuanzhao said indifferently: "Please take a look."

The hand holding the dagger moved, and Hua Yuanshan was so frightened that she quickly held the dagger tighter.

"My reaction speed is not as fast as my cousin's. If I want to kill her with one blow, I can only control her from behind first, and then stab her." Hua Yuanzhao said calmly.

"But if that's the case, the victim will definitely struggle. Even if the knife is stabbed into the heart, the victim will not lose the ability to move immediately. The dagger will definitely cause secondary damage to the blade during the struggle."

"The wound enlarged and blood gushed out in large quantities, so the victim's hands must have been stained with blood, but the fingertips of the corpse were clean."

"This is sufficient to prove that the victim was stabbed while unconscious or even dead."

Hua Yuanzhao glanced at Hua Yuanshan, who was almost fainting, and relaxed his hold slightly.

"To put it another way, this is a remote place. If the murderer really wanted to hide the evidence, he would just throw the murder weapon into a corner, or at worst into the river."

Hua Yuanzhao sneered: "How could he bring it back to the yard where he lives and bury it under a tree as if to cover it up?"

"Hua Yuanshan, tell me yourself, why was the dagger in my residence, and why are you so sure that I was the one who killed him?"

Hua Yuanshan finally took a breath, and when she heard the voice, she looked at the Prime Minister and Gu Changsu with tears in her eyes, asking for help.

"Eldest sister, are you trying to say that I buried the dagger and framed you?" Hua Yuanshan burst into tears: "Eldest sister is so vicious, how dare I?"

"You evil creature! It's not enough that you've harmed people, but you also want to frame your sister!" Prime Minister Hua was furious and anxious, staring at the dagger in her hand without letting go.

"My daughter is just a reasonable assumption!" Hua Yuanzhao sneered: "When your sister comes right up and labels me as a murderer, that can be called a false accusation!"

"Let Shan'er go first!" Prime Minister Hua was overwhelmed and afraid that she would hurt someone.

Watching this farce, Gu Changsu suppressed his anger and said, "Since you said the wound is not fatal, then you can check it!"

"Let go of the Second Miss! I'll give you a chance to prove your innocence! But if you can't find out anything..." Gu Changsu snorted coldly, and his eyes were filled with murderous intent as he looked at her.

"Based on the existing evidence, you are the biggest suspect!" Gu Changsu made the final decision.
