Duke Wanguo smiled and said, "There is something I need to discuss. How much did Princess Chen spend on the physician? I would like to ask this physician to treat Madam's health. If possible, I would like him to stay at the manor for a while."

Su didn't like him to begin with, and hearing him make this request only made her more annoyed, so she refused on the spot.

Su Yuan made an excuse that his health required him to stay with this doctor and that he did not intend to send him to another doctor.

Duke Wanguo said regretfully, "A skilled doctor is hard to find. How much silver will this doctor charge for his diagnosis and treatment? I'll find someone with the same price."

Su Yuan said, "It was Princess Consort Chen who found it, and she also paid for it. I don't know anything about it."

"Did she say how long the doctor can stay here? If he can't be cured in three or five years, will she keep paying him?" Duke Wan asked, getting to the heart of the matter.

After saying this, he sensed displeasure from Su Yuan's distorted features.

Su Wenyuan came here today specifically to discuss this matter, which put Su Yuan in a bad mood. Now, the Duke of Wanguo is asking about it again, which is like rubbing salt into his wounds.

"Why don't you just say what you want to ask today?" Su Yuan was unwilling to beat around the bush any longer.

The Duke of Wan hesitated and refused to speak.

If he asks directly, what I've done will be exposed, and I might be in danger.

Seeing that he was unwilling to talk, Su Yuan was about to see the guest out, not wanting to say anything more.

Since he fell ill, he has only thought about himself and is not afraid of offending anyone, even though things have already come to this.

He only cared about whether his illness could be cured and didn't want to engage in hypocritical conversations with these people.

Instead of wasting time on this, you should rest properly, which will also help your body recover.

The Duke of Wan reluctantly got up, but after taking only a few steps, he seemed to have made a major decision and came back.

“Princess Consort Chen wouldn’t have called a doctor for you for no reason. I want to know how you persuaded her.” Duke Wan’s expression was solemn.

Su Yuan remained silent, thinking to himself that this man was truly insidious.

Without explaining why he asked or what the connection was with him, he just wanted to get clues out of Su Yuan.

Su Yuan was also tired. Rather than testing each other, she decided to remain silent.

If he can't wait, he will naturally speak first to explain his purpose.

Su Yuan's silence made the Duke of Wan realize that Su Yuan wouldn't speak unless he said something first.

“I once tried to stop Prince Chen and Princess Chen from investigating what happened back then.”

Su Yuan ignored him, staring straight ahead without moving.

The Duke of Wan Guo added, "At the same time, General Yin's mother and Wu Hekai's mother also joined in the obstruction."

It took Su Yuan a while to process the appearance of these two names.

He remembered General Yin, but who was Wu Hekai?

When the Duke of Wanguo saw that he did not remember, he reminded him, "Do you know where Jinshan is now? This man also served in Jinshan thirteen years ago."

The closest small city to Qikong Kingdom is called Jinshan City. When the two countries were at war, they were stationed in Jinshan.

Su Yuan suddenly realized, "Thirteen years ago, they were all at the crossroads of the two countries. Cha Anlehou would have an impact on them, so they wanted to stop him. But you are far away in the capital. What does this have to do with you?"

"Could it be that you are the one who truly betrayed the country? And you were the one who sent the message to Qikong Kingdom? You colluded with each other, and when things were about to be exposed, you framed Marquis Anle, leading to the tragic death of his entire family!"

Duke Wan did not immediately refute, but after thinking for a while, he said slowly, "Things are not as you think, there are deeper connections that you cannot imagine."

Su Yuan said, "That's enough for me. It's not like I want to overturn the case against Marquis Anle. Why did you come to me?"

He was a partially disabled patient who couldn't do anything.

The Duke of Wanguo said, "I want to know what clues you provided to Su Wenyuan."

He stared intently at Su Yuan, fearing that Su Yuan was hiding something and refusing to tell the truth.

Su Yuan noticed his nervousness and guessed that he was involved in something serious.

The death of Marquis Anle was not simply a case of wrongful conviction.

Regardless of the truth, he has no intention of getting involved; he can't control it and doesn't want to get involved.

“If you hadn’t come to me, I would never have imagined that what happened back then was related to you. What do you think I could tell Su Wenyuan? You saw for yourself how my relationship with Marquis Anle was back then.”

Everyone could see that Marquis Anle was rejecting and disliking Su Yuan.

For years, they always treated Su Yuan as a joke.

Duke Wanguo wore his doubts on his face and said, "You're not trying to fool me into thinking that you and Su Wenyuan do have a father-daughter relationship, are you? That she saved you out of affection?"

Su Yuan said, "I'd like to, but I don't think you'd believe me."

The Duke of Wan Guo appealed to his emotions and reasoned with him, talking about sentiments and the past, but none of that was as effective as 20,000 taels of silver.

After handing the silver note to Su Yuan, he said one sentence: Yu Qingzhu gave him a picture, which he then gave to Su Wenyuan. It was because of this picture that Su Wenyuan hired a doctor for him.

Su originally thought that the Duke of Wan would be angry after hearing this, feeling that he had been tricked.

Unexpectedly, the Duke of Wanguo said nothing and got up to leave.

Su Yuan was surprised. He hadn't realized this news was so important. He should have asked Su Wenyuan for more benefits if he had known.

After Duke Wan returned, he took out the picture again and studied it carefully.

Why did he not discover anything about this map even after having it for so many years?

Su Wenyuan had barely gotten her hands on it when she noticed something amiss?

The Duke of Wanguo continued his research. With the help of Nian Huaizhong, Su Wenyuan had determined the purpose of the map: it was a marker for hiding things.

The various symbols in the picture are actually drawings, depicting what's inside.

You can't recognize something until you see it; once you have it in your hands, you can tell.

The painting depicts a wine cup, a broken sword, and an incense burner, all of which are quite realistic.

Those who don't know might think it's some kind of mysterious script, but it's actually just a sketch drawn by someone who can't draw.

This picture serves as a hint, since the hidden compartment is well concealed and difficult for ordinary people to find.

Even someone as skilled in mechanics as Nian Huaizhong, after searching for so long, still made a mistake.

Without this picture, I really wouldn't have been able to find everything.

Those empty spaces were just something I did while creating the product. There was nothing to put in them, so they're left empty; they're not shown in the image.

The items are all in Su Wenyuan's hands now—a bunch of old things that nobody would want even if they were thrown on the street.

It's so dilapidated, covered in rust, and parts of it have already started to weather.

It was worthless to begin with, and now it's unusable and has no aesthetic appeal.

Su Wenyuan couldn't understand why they would specially create hidden compartments and mechanisms just for these things.

Sheng Jingyu and she studied together for a while, but they also found nothing.

However, he was sent to Jinshan to investigate the guards who fought between the two countries thirteen years ago, and he made some progress.

In that battle, Yasukawa Province faced significant problems.
