"You said I killed my second brother, what evidence do you have?" Cao Zhang asked Cao Pi.
"The servants in the second brother's house saw you putting something in the wine with their own eyes! The remaining wine in the house has also been tested and it contains highly toxic substances. This is the evidence!" Cao Pi said.
"This time there are not only witnesses, but also physical evidence. You can't deny it!" Cao Pi said the word "physical evidence" in a serious tone.
"Really? There is still physical evidence. Then call me and see the witnesses." Cao Zhang responded calmly.
Cao Cao waved his hand, and a guard came up with a wine jar and placed the wine jar in front of Cao Zhang.
Following behind were several butlers and servants.
Cao Zhang lowered his head and glanced at the wine jar. There was still half a jar of wine in the jar.
"A jar of new wine, now only a small part is left. Could it be that the second brother drank it alone, and I never took a sip again?" Cao Zhang said with a sneer.
"Second brother was already drunk at the time, and you know the wine is poisonous, so naturally you won't drink it again!" Cao Zhen said.
"That's right. After Young Master Ziwen let go of the medicinal powder, he kept urging my young master to drink. He never drank again. It didn't take long before he fell to the ground drunk!" The servants also echoed Cao Pi's words.
"After I fell, did someone carry me away?" Cao Zhang immediately asked.
"Yes..." the servant responded.
Cao Zhang caught the loophole in the servant's words and immediately interrupted him: "That means that when I was carried away, my second brother was fine? Then why do you conclude that he was killed by me? "
"Because my young master is already drunk first, we sent him back to the room first."
"Early this morning, we wanted to wake the young master up, only to find that he had been poisoned to death. Then we remembered that Mr. Ziwen had drugged the wine, and hurriedly reported it to Sikong!" the housekeeper defended.
Cao Cao's face darkened again and he looked at Cao Zhang quietly: "Do you have anything else to say?"
"Father, I have a way to prove my innocence and prove that these servants framed me!" Cao Zhang responded calmly.
Cao Cao looked at Cao Zhang in disbelief. He didn't expect that this bratty boy who only knew how to dance with guns and sticks since he was a child would give him a strange feeling today.
I have always hoped that Cao Zhang could study more and learn more strategies.
But Cao Zhang always said that his ambition was to be a general leading troops and refused to study.
Cao Cao tried to persuade him several times to no avail, so he had no choice but to give up.
But what Cao Zhang did today was far beyond Cao Cao's expectations.
The method used to prove that he did not rape the princess was crude, but extremely effective. In fact, it took great wisdom to think of it.
He is now saying that there is a way to prove that Cao Shuo's death had nothing to do with him? Is this a bluff, or is he confident?
"How to prove it?" Cao Cao asked.
"Please father, please bring the second brother's body, and I can tell everyone the truth!" Cao Zhang responded confidently.
Cao Cao waved his hand immediately without any hesitation.
After a while, Cao Shuo's body covered with white cloth was carried into the hall and placed on the ground.
"Second brother!" Cao Zhang stepped forward, knelt in front of Cao Shuo's body, threw himself on his body and began to cry loudly.
Everyone obviously didn't expect that he had such a skill, and they were all stunned.
A sneer appeared at the corner of Cao Pi's mouth: So your so-called self-proven innocence is just to pretend to be pitiful here and try to gain your father's sympathy? Then you made the wrong idea!
Cao Cao looked at Cao Zhang who was shouting loudly in front of him, his face became ugly, and he couldn't see Cao Zhang's intention for a moment.
"That's enough, stop pretending here! Someone, drag down the murderer who killed my second brother!" Cao Zhen shouted loudly.
Cao Cao did not speak to stop him, and several guards rushed towards Cao Zhang again.
However, Cao Zhang suddenly raised his head at this moment, stretched out his hand to block the guard, and said loudly: "I have found the evidence!"
Cao Zhang's words shocked everyone. Cao Cao then waved his hand and the guards quickly retreated.
"Say, what did you find?" Cao Cao looked at Cao Zhang and asked.
Cao Zhang pointed at Cao Shuo's body and said loudly: "I have found out that the second brother was not poisoned to death by poisonous wine!"
"Nonsense, the medical officer has just used a silver needle to check the second brother's throat. It is black. How dare you say that he was not poisoned to death?!" Cao Pi yelled loudly.
Cao Cao stared at Cao Zhang, obviously he also thought Cao Zhang's words were nonsense!
"What I said is true! If you don't believe it, you can try the second brother's abdomen with a silver needle. If he really dies of poisoning, even if the silver needle is inserted into the abdomen, it will turn black!" Cao Zhang said loudly.
Cao Cao waved his hand, and a medical officer came in from outside the door, came to Cao Shuo's body, and inserted a silver needle into the abdomen for examination.
Everyone held their breath waiting for the moment when the silver needle was pulled out.
When the silver needle was lifted, it really didn't change color.
"Did you see it? The silver needle did not turn black, which means that the poison did not enter the second brother's abdomen at all, and he was not poisoned to death by poisonous wine at all!" Cao Zhang said loudly.
"Just because the silver needle didn't turn black, you're saying that the second brother wasn't poisoned to death by poisonous wine? Maybe it's just that the silver needle failed!" Cao Pi was still quibbling.
"Can silver needles malfunction?" Cao Zhang smiled, "Then let me ask you, how did you prove that the residual wine was poisonous and you also used a silver needle to test it?"
"Are you trying to say, is there something wrong with this wine?" Cao Cao understood the meaning of Cao Zhang's words and asked directly.
"Exactly. I beg your father to order someone to bring a dog and bring you a piece of meat. I will prove it to my father."
After a while, a dog was brought in. Cao Zhang soaked the meat in the residual wine for a while, and then threw it to the dog.
After the dog ate the meat, within a few moments, it began to twitch all over, and then its tongue stuck out and died.
"We have known for a long time that the wine is poisonous, but you are doing it unnecessarily." Cao Pi said contemptuously.
"It's true that the wine is poisonous, but I just put the meat in it and soaked it for a while, and it was enough for the dog to eat it and kill it on the spot!"
"According to the previous servant's confession, the second brother drank half a jar of wine by himself, but he was only drunk and was sent back to the house. He was not found dead until dawn."
"It should be clear whether he drank poisonous wine to death, right?" Cao Zhang explained very calmly.
"This..." Cao Pi was speechless.
The corners of Cao Zhang's mouth raised slightly, revealing a smile.
When he saw half the jar of wine left, he discovered the problem.
As a forensic doctor, he smelled the smell of aconitum in the wine just by smelling it with his nose.
In the late Han Dynasty, the poison-making technology was not perfect enough, and colorless and odorless poison could not be produced.
The toxicity of aconitum is very powerful. Generally, it only takes 3-4 mg to cause death, and at this moment, it is impossible to make it into a chronic poison.
Based on this, Cao Zhang concluded that there was another reason for Cao Shuo's death, so he proposed to see his body with his own eyes.
Cao Cao looked at Cao Zhang in front of him and was extremely surprised. He didn't even notice the details of the poisoned wine, but Cao Zhang saw through it. How could he suddenly have such careful thoughts?
Before Cao Cao could think clearly, Cao Zhang had already said another sentence that shocked him.
"Father, the second brother was not poisoned to death by poisonous wine at all, but was bitten to death by a poisonous snake!"
