Drive a RV and go farming in ancient times.

Why are cakes poisonous? Since it was to silence him, the eldest prince was already fidgeting, subconsciously avoiding Sun Yu's sight, lowering his eyes, staring at the tea rippling in the cup.

He didn't want to listen anymore, but obviously, Sun Yu wouldn't let him escape. He asked him one question after another, digging up the old stories that he had tried to forget.

"The villagers have exactly the same symptoms as the emperor's eldest grandson. If this is a coincidence, who would believe it?"

"You were not at home at the time and failed to deal with it in time, which is understandable, but afterward, didn't you investigate?"

"The fights between your wives and concubines are your own business, but those more than a hundred people shouldn't have died in vain. Their deaths were so unjust. They knew nothing and were killed without knowing anything. They were even killed under the pretext of plague. They will die with regrets!"

"They are not servants of your mansion, for you to do whatever you want with them. They are the people of Dayong. Shouldn't they get justice for their death? Otherwise, where is justice?"

The eldest prince's handsome face gradually turned pale, his hands in his sleeves clenched into fists, and his whole body tensed up.

Sun Yu seemed not to notice his embarrassment, nor did he show any mercy. He continued slowly, "Six years ago, the emperor's grandson was poisoned, and Your Highness was not at home, so you missed the best opportunity to track him down. What about last year? The emperor's grandson was attacked by mountain bandits, and it was only two days away from the capital by galloping. Did you go to the scene of the incident and investigate carefully afterwards?"

The eldest prince subconsciously defended himself, "My father sent Marquis Dingyuan to investigate. Marquis Dingyuan's ability is far superior to mine. When I heard the bad news, I was so heartbroken that I even had difficulty walking..."

Sun Yu looked at him expressionlessly and thought, no wonder no matter how fiercely the other princes fought, they failed to drag the eldest prince into the battle, it was really because this prince was too useless. To put it nicely, he has a gentle and kind temper, to put it bluntly, he is weak and incompetent. He couldn't protect his original wife, nor his eldest son, and he was suppressed by his concubines without the ability to fight back. Is he still a prince?

Men from ordinary families would not be so cowardly.

It was no wonder that even the emperor was too lazy to intervene. How could the emperor not know about the affairs of the eldest prince's mansion? He knew about it but turned a blind eye because he was extremely disappointed. The eldest prince could not stand up on his own, and if others intervened, it would only help him temporarily, not for a lifetime.

"That's your eldest son, the eldest grandson of the Emperor of Dayong. He should be honored with a golden crown, but where is he now? Why did he end up with such an unknown fate, Your Highness, have you really never thought about it? It is because of your indulgence time and time again that some people have become more and more daring and reckless, and have lost their sense of proportion..."

The eldest prince's eyes trembled, and he spoke in a hoarse voice, "Do you have evidence? Do you have evidence of what happened last year?"

Sun Yu said, "No, but you know it in your heart, and I know it in my heart too. Anyone with a discerning eye can tell who has the motive and who has the ability."

After a pause, he said meaningfully, "If you really want evidence, it's easy. Just have someone interrogate Li Yuan. He was involved in what happened six years ago, and he was most likely involved in what happened last year. Now that he's locked up in the Jingzhao prison, it's easy to interrogate him."

But does the eldest prince dare?

Of course the eldest prince didn't dare to do that. He already had the answer in his heart, but he just didn't dare to face it.

The room was elegantly decorated and the aroma of tea was pleasant, but the atmosphere was so dull that it made one feel breathless.

After a while, the eldest prince relaxed his tense nerves and asked self-deprecatingly, "Am I too incompetent?"

Sun Yu did not respond. Although he came here with his face masked to conceal his identity and was somewhat dissatisfied with the eldest prince, the prince was still a prince after all. Although he was dissatisfied, he would not look down on him.

The eldest prince could not wait for his response and laughed bitterly, "Even if you don't say it, I know it. I know even better how others see me. They must think that I am weak and incompetent, and unworthy of being a prince..."

But who knows his pain? Is he born this way? Is he willing to be treated badly and suppressed?

Since he was a child, he has been an insignificant person in the palace. His biological mother was of humble status and died early. His situation can be imagined. His father did not value him, the court officials did not care about him, and those so-called brothers did not take him seriously. Anyone could bully him. Even the eunuchs and palace maids looked down on him. They could still be perfunctory in front of others, but often embarrassed him behind his back. How could he survive?

First, he had a good life, and second, he had to endure everything that was intolerable, so that he could survive in that cannibalistic palace, live to move out of the palace and build his own house, live to get married and have children, live to a time when everyone ignored him and did not regard him as an opponent. He could finally be a leisurely prince that people could trust, not getting involved in anything, just living his own little life behind closed doors, drinking tea, painting, reciting poems and appreciating music. If life were like this, how comfortable and happy would it be?

For this reason, he turned a blind eye to the things happening in the mansion, telling himself that it is rare to be confused in life and that only by being confused can one be free. In fact, wasn't this just the cowardice in his bones at work?

He was afraid of destroying the current peace and comfort, so he would rather pretend to be deaf and dumb, but now, he can no longer pretend.

Sun Yu calmly watched him struggling with himself, and suddenly he felt a strange feeling in his heart. When the concubine was chosen for the eldest prince, the unpopular bastard from the Changle Marquis's Mansion was chosen. This was normal. No matter how mediocre the eldest prince was, he was still a prince and had an elder position. Even the concubine could not be from a humble family. But later, how could the Earl of Pingyuan be willing to send his legitimate daughter to be a concubine?

No matter how nice the title of concubine sounds, she is still a concubine. The Pingyuan Marquis' Mansion has indeed been on the decline in recent years and has lost its former glory. However, since the emergence of the Princess of Anping County, there are signs of regaining its glory. The legitimate daughter of the family naturally has a better future. There is no need for her to be a concubine. Even if she wants to be one, she should choose other princes. The eldest prince does not have the ability to ascend to the throne. Wouldn't it be a waste to follow him?

The more he pondered, the more puzzled he found it. The eldest prince seemed to have made up his mind. He gritted his teeth and asked, "What do you want, Your Excellency?"

Sun Yu came back to his senses and said calmly, "I just want the perpetrators to receive the punishment they deserve, and to comfort the souls of the more than one hundred people in heaven."

The eldest prince asked, "You want Li Yuan's life?"

Sun Yu asked back, "Don't you want to?"

The eldest prince murmured, "He probably thought so. He also owes my son a life..."

Sun Yu reminded, "Maybe there is also your uncle's."

After all, Han Jun is now missing, alive or dead.

The eldest prince's body swayed, and a trace of pain flashed in his eyes, "I'm sorry for them..."

Sun Yu pressed on, "You now have a chance to avenge them. Li Yuan is already in prison, waiting for a day to be sentenced."

The eldest prince smiled bitterly, "Can Jingzhao Prefecture sentence him?"

Sun Yu's eyes were firm. "Yes, as long as you come forward and make your attitude clear to Qiao Hong, and let him handle it impartially."

The eldest prince was stunned for a moment, "That's it?"

Sun Yu nodded.

The eldest prince shook his head. "Your Excellency thinks too highly of me. Do you think Qiao Hong is afraid of me? You are wrong. What he is really afraid of is Marquis Changle. My statement is meaningless. If Marquis Changle wants to protect Li Yuan, then Qiao Hong will definitely make a big deal out of a small matter, or a small matter out of nothing..."

After a pause, he endured the embarrassment and added, "Although Marquis Changle is my father-in-law, his heart is not with me."

Sun Yu's eyes flickered. He was not surprised to hear this. He had long felt that there was someone else behind Marquis Changle. It was totally unrealistic to put the hope on the eldest prince. "I will keep an eye on Marquis Changle. You can rest assured."

Hearing this, the eldest prince asked hesitantly, "Does your Excellency have a grudge against the Changle Marquisate?"

Sun Yu thought that the one who had a grudge was his apprentice, but there was no difference between master and apprentice, so, "I guess so."

The eldest prince suddenly realized and trusted him a little more. "Okay, I will make my position clear to Master Qiao. I will never show favoritism... and I will not let other people in the palace show favoritism."

This means that the Crown Prince's wife will be well disciplined.

Sun Yu reminded, "If necessary, you can tell Qiao Hong that the emperor's eldest grandson was poisoned, and the poison he was poisoned by was the same as that of the villagers in Hutian Village."

"is it necessary?"

"Yes, only in this way will Qiao Hong give Li Yuan a heavy sentence. You don't want to just beat him with a few dozen sticks, confiscate some silver, and then let him go, right? There are so many lives at stake, including the emperor's eldest grandson and your uncle..."

These words, every time said, were tantamount to public execution for the eldest prince. He interrupted with a pale face, "Okay, I understand."

Sun Yu said meaningfully, "Your Highness, don't be optimistic. Although Zheng Chunxiu is gone and the villagers are dead too, if we really want to investigate, there are many ways. We can open the coroners and do autopsies. An experienced coroner will easily find out that those people died of poisoning. As for what kind of poison, a skilled doctor can also tell. As for the emperor's eldest grandson, the folk miracle doctor invited by Han Jun is still alive. It won't be difficult to find him if we take the trouble to find him."

After hearing this, the eldest prince said dejectedly, "I understand, but this matter ends with Li Yuan, right?"

Sun Yu said without hesitation, "Of course, I have no right to interfere in your family affairs. You can handle it yourself."

The eldest prince secretly breathed a sigh of relief.

No one knew the conversation between the two people, and Xu Huaiyi could only guess part of it. After he met Sun Yu, he did ask about it, but Sun Yu's answers were vague and asked him to wait for the result.

Xu Huaiyi pondered for a moment, and when he entered the RV at night, he said to Gu Huanxi, "Master may really have another identity."

Gu Huanxi asked curiously, "Where is the evidence?"

Xu Huaiyi pondered, "He seemed to avoid talking about the details of his conversation with the eldest prince, as if he was afraid that I would notice something. Logically, he shouldn't distrust me so much. It's not a secret. So, there is only one possibility, that is, he didn't meet the eldest prince as Sun Yu, so the way of speaking would definitely be different."

Gu Huanxi nodded, "That makes sense, but what is his other identity?"

Xu Huaiyi helplessly spread his hands, "I don't know. I can't ask Li Yunting to check him out, right? There's a high probability that he won't find anything, and it will cause trouble..."

"Then you should just play dumb. If there is any problem with his identity, at least ignorance is not a crime."

"Um……"

Gu Huanxi asked about the progress of the case again, and Xu Huaiyi said, "The eldest prince has already stated that he will not side with Li Yuan, but there is still the Marquis of Changle. Let's see what he will do next."

However, Xu Huaiyi did not expect that the King of Chu would secretly intervene, because Qiao Hong's subsequent attitude was obviously biased towards Li Yuan. According to the rhythm, Li Yuan would at most be guilty of dereliction of duty for lax supervision, or even this charge might not even be used. After all, six years ago, Li Yuan had no official position and was just an accompanying official. The subordinates of Marquis Changle were the ones who took the blame.

As for the poisoning, there was another explanation. It was that Zheng Chunxiu and the emperor's eldest grandson's wet nurse had worked together to do it. Because they were dissatisfied with the eldest prince's wife at the time, they vented their resentment on the emperor's eldest grandson. Anyway, both of them are dead now, there is no evidence, and there is no need to worry about a detailed investigation.

Of course, the only person who guessed that it was the King of Chu who intervened was Xu Huaiyi. He had read the letters of Yao Changjun, so he knew clearly who in the court was in collusion with the King of Chu, such as Qiao Hong, the Pingyuan Marquis' Mansion, and the Changle Marquis' Mansion. However, he did not expect that the King of Chu valued the Changle Marquis so much that he would risk his life to save him at this time.

Is Li Yuan worth it?

Xu Huaiyi couldn't figure it out, but Gu Huanxi saw it clearly. "When Yao Changjun got into trouble, the King of Chu not only didn't save him but also killed him to protect himself. Although he made compensation later and married Qiao Hong's daughter to Yao Changyuan, if you really want to calculate, the King of Chu's actions will inevitably make his followers feel cold and indifferent. He can't let them feel disappointed again, otherwise, who will be willing to support him in the future?"

Xu Huaiyi suddenly realized, "So, no matter whether Li Yuan is worthy or not, or whether he is useful or not, he must be saved. This is a matter of attitude."

"Well, but I guess that the Changle Marquisate should still be of use, right? Otherwise, the risk this time is not small. The King of Chu must have seen that someone is backing Hutian Village behind the scenes, with the purpose of dealing with Li Yuan. He dared to take action without even knowing who the other party is. This intention is a bit too much..."

Xu Huaiyi's heart moved, "It is indeed a bit unreasonable, unless Changle Marquis Mansion is a force that he cannot give up."

The couple looked at each other, and both had some guesses in their minds, but no evidence.

In fact, Gu Huanxi's back began to shiver as she thought about it. If her guess was true, then the King of Chu was too insidious. It would be fine if nothing happened, but if something happened, the eldest prince would be the best scapegoat. After all, Marquis Changle was the eldest prince's father-in-law. Wasn't it natural for her to plan for him?

Everyone would think so, especially the princes. At that time, the eldest prince would be a living target standing in front of the King of Chu.

"Should you tell your master about this?"

Xu Huaiyi thought about it and shook his head. "The timing is not right. We don't have an excuse to convince him. If we don't do it well, we might be exposed again. Let's wait a little longer."

"But now, the King of Chu has intervened, and your master is not aware of it. What should we do next? We don't have the strength to compete with the King of Chu..."

Xu Huaiyi smiled meaningfully, "Have you forgotten those letters? What do you think the inspectors will do if I give them to them? By then, will the King of Chu still care about Li Yuan's trivial matters? Even if he values ​​Changle Marquis's Mansion, he has to prioritize. As for Changle Marquis, we will all prosper together and suffer together. If he helps the King of Chu to deal with the aftermath, he can only give up his son Li Yuan. After all, he is just a bastard, and he doesn't need him."

At this point, he thought of something and said proudly, "We have to stimulate Li Ji again, let him play a supporting role and add fuel to the fire. For the reputation of Changle Marquis's Mansion and for his own status, I think he would be most happy to get rid of Li Yuan, this ambitious opponent."

"You're thinking?"

"Well, we can use the thunderbolt punishment from heaven again. Last time, Li Yuan got away with it and used an unpopular half-brother as a scapegoat. We won't be so lucky this time."
