The sickly son died young? After the marriage exchange, I will bring prosperity to his entire clan f

"How sure are you?"

Ling Silang gave Du Mingxian a deep look, and finally said bluntly, "I'm not sure."

Du Mingxian held the medicine, speechless. "Are you... are you kidding me?"

“I have never been in contact with Chun Tao, so I don’t know how skilled she is with poisons. Based on the poisons she gave you and the poisons we took, I can only conclude that her poison skills are very powerful.”

Seeing that Du Mingxian was still looking at him, Ling Silang could only force an explanation, "Unless it is particularly powerful, she will have to put in some effort to cure my poison."

Du Mingxian wanted to say something more, but in the end she could only sigh. It seemed there was really no way. The two of them had no connection. Besides, it was already quite impressive that he could produce these poisons in such a short period of time.

Have you ever had contact with the imperial physicians?

"Have."

"Could the people from the Imperial Medical Academy easily detoxify you?"

"No."

"That's good. We won't be greedy. As long as we can keep the imperial physician from finding out the truth, Chun Tao will definitely be anxious when she hears this news. Once she's anxious, I'll be able to tell who it is."

Ling Silang nodded silently. "Who do you plan to use for the trial?"

“The Crown Prince is definitely out of the question. He is the eldest son and the heir apparent, so he couldn’t have done these things. Besides, he’s sickly himself. If he were to take this medicine and kill someone, it would be a real mess.”

After hesitating for a moment, Ling Shilang suggested, "How about we start with the one that's most likely?"

Du Mingxian shared her opinion: "Except for the Crown Prince and the Second Prince, the others are all very likely, each with their own advantages, so at this point... we can't analyze who it is, we can only use the process of elimination."

“Alright, shall we start with the Third Prince?” Ling Silang suggested after finishing his sentence. “Although the Second Prince doesn’t seem like it at all in the past, you can’t judge a book by its cover. Sometimes the least likely thing is the most likely thing.”

“Naturally, you think the same way I do. I think we should start with the Second Prince. Now all the princes are potential candidates, and none of them can be ruled out.”

Ling Silang agreed.

However, drugging princes was not an easy task and involved a lot of trouble. First of all, each prince had several eunuchs who would taste the food. Only if the eunuchs ate it and were unharmed would the princes eat it.

"How do you plan to administer the medicine? But this is a tricky matter."

"If it's too difficult, I'll figure out a way. If I can't think of a way, I'll... plan to risk going directly to their residence and secretly feed them the medicine under the cover of night."

Ling Silang shook his head repeatedly, "No, no, this is too risky. If we are discovered, the consequences will be unimaginable."

"Then I'll go back and discuss it further."

"Okay, I'll let you know as soon as I come up with a good solution."

"Okay, I've been thinking about the border defense map lately. What should I do? I've already drawn it, but I'm unwilling to give it to the person behind it."

Ling Silang remained silent for a long time, then said, "Actually, this matter... why don't you tell the Crown Prince? I feel that the Crown Prince is trustworthy."

"Tell the Crown Prince that this is a huge matter, and this will be his future empire. Are you sure he won't use us as a scapegoat?"

In her previous life, the crown prince died young, but who can guarantee that certain things will definitely happen in this life? There is still a certain probability.

She told the Crown Prince that she really didn't dare to think about it.

“The Crown Prince is physically weak, but he is a good man. He cares about the people of the world, so if he knows about this, he will definitely help you find a way. Some things are difficult for us to do, but they will be very easy for the Crown Prince to do.”

Du Mingxian felt that Ling Silang's words made some sense. "Then I will come to see the Crown Prince again tomorrow. If not today, you can have your servants in your courtyard pass on a message to the Crown Prince for me. I will come again tomorrow night."

"Alright, but be careful. Don't worry about the Crown Prince's residence, just beware of spies."

"I know."

After the two finished discussing, Du Mingxian was about to leave. Ling Silang watched her leave, still feeling a little worried. Originally, nothing should have happened, but they were just unlucky.

The next evening, Du Mingxian arrived early, and the Crown Prince had specially prepared pastries, as if he had been waiting for her.

Upon meeting the Crown Prince, Du Mingxian didn't stand on ceremony and went straight to the point, "Your Highness, since you know we are fake, you should also know our mission. Now... I don't know how to complete this mission. I wonder if Your Highness could give me some guidance."
