Four days later, Li Wei arrived in Dingyuan County again after a month. At this time, there was a little warmth in the air, and the willow branches had sprouted new buds, and geese and ducks played in the river, and flocks of birds flew past the air. From time to time, you can see herder boys riding buffaloes leisurely passing by the river. The spring of the 23rd year of Hongwu has arrived.

Li Weizheng did not have the heart to feel the first spring after the Ming Dynasty. The task assigned by the prince made him feel heavy. He originally thought that the assassination was just an opportunity for him to take advantage of the prince, but he did not expect that the assassination incident would become the introduction of Lan Yu, the last of the four major cases in Hongwu. He remembered that the Lan Yu case occurred in the 26th year of Hongwu, that is, three years later, but gradually he realized that the major case that occurred in the 26th year of Hongwu only blossomed and bear fruit, and its seeds, its roots and sprouts, had actually begun early.

Li Wei was riding on a horse and asked a farmer who was busy in the wheat field where the Lan family was. The old farmer pointed to the northeast, and he immediately rode his horse and galloped northeastward.

Li Shanchang, Hu Weiyong, Lan Yu and Mu Ying are known as the four major families of Dingyuan County. Their mansions are almost everyone knows. Just like Beijingers know Wangfujing and Shanghaiers know Nanjing Road, Li Wei was running along a wide country road for a quarter of an hour. He saw a large manor covering an area from afar. The tall walls surrounded it. There was a forest next to it, and there was endless wheat fields around it. Here was Lan Yu's old house.

Li Wei was leading his horse to the gate of Lan Yu Mansion. Suddenly, with a 'ao!', two huge stubborn dogs rushed towards him. Li Wei was shocked and took two steps back. The iron chain sounded, and the two stubborn dogs were tied to the stone lion at the door, roaring at him wildly. Li Wei's face sank, and the iron chain of the dog was five or six feet long. If ordinary farmers got closer, what's the difference between this and not stubborn? Although the matter was small, Li Wei Zheng felt the rampant Lan Yu Mansion in the village.

"Is there anyone in the mansion?" Li Weizheng shouted in a deep voice. He clearly heard footsteps behind the gate, but he refused to come out for a long time.

"I came from the Beijing city to report the news." He shouted again.

At this time, the small door next to him finally opened. Two Zhuang Nu in black walked out, both of whom were quite arrogant. He looked at him and asked coldly: "Who are you sending a letter to?"

Li Wei was unwilling to deal with these slaves, so he snorted: "Go and inform your master quickly. It's a big deal. If you miss it, you can't afford to take care of it."

The two Zhuang Nu looked at each other. Although Li Weizheng was dressed inconspicuously, the horse he rode was very majestic, unlike ordinary people who could have it. One of them nodded and reluctantly said, "Okay! We can inform you, but at least you have to explain who sent you to deliver the letter?"

"Tell your master, he wrote a letter to the capital half a month ago, and I came for this letter."

Seeing that he was speaking seriously, Zhuang Nu did not dare to delay, "Wait." The two of them turned around and entered the mansion gate, and with a loud bang, the side door closed heavily again.

After about a cup of tea, another clamor of rapid footsteps sounded inside the door. Not only one person, the side door opened, and a large group of servants walked out surrounded by a man. He was about thirty years old, tall and strong, and heroic. Although he was good, he had an unconcealed arrogance in his bones. Especially when he looked at Li Weizheng, his eyes were full of disdain and suspicion. This person was Lan Yu's fourth son Lan Chuo. Lan Yu's secret letter was lost because of his carelessness.

It is no wonder that the hierarchy concept was very strong in the early Ming Dynasty. It can be seen from the dress that ordinary people without fame could only wear blue, gray, black and other colors, and their shoes and hats were also stipulated. If they were surpassed, they would be arrested and imprisoned immediately. Therefore, only Li Weizheng's blue shirt could be seen at a glance. Therefore, the evil dog roared and roared at him. The reason why the people in the sect didn't care about it was this. If he hadn't mentioned the letter half a month ago, he would have been beaten away by sticks and wanted to see his master, it would have been a daydream.

Of course, another reason why Lan Chuo suspected him was that the prince's guard Yu Ping had already arrived yesterday and had taken over the case in full. He really couldn't think of anyone else who would know about this.

"I am the master here. Who are you sending a letter to? Where is the letter?" Lan Chuo was displeased when he saw Li Weizheng not speaking.

Li Weizheng suddenly understood why this person had such a stupid thing as losing a confidential letter. That is, he had no secret heart at all and did not understand the truth that the walls were heard. At the gate, in front of so many servants, would he have to say that I was sent by the prince and then take the prince's gold medal to show him? It is hard to say whether he can still walk out of Dingyuan County alive.

Li Wei glanced at the people on both sides and said lightly: "This is not a place to talk. If you are the fourth son of Duke Liang, then I will be looking for you."

Lan Chuo looked at the people on both sides and then reacted a little. He pondered for a moment and said, "Okay! Take this person to the small room to see me."

There were no extra people in the small room, only two personal bodyguards stood behind Lan Chuo, looking at Li Weizheng vigilantly.

"Okay, what's wrong with you? You can tell me now!" Lan Chuo saw that the other party was sitting in a daze, a trace of anger flashed in his eyes, and his tone became tougher.

Li Weizheng was not angry at all. He took out the prince's gold medal and waved in front of Lan Chuo, "Do you know this?"

Lan Chuo's eyes suddenly widened. Although it was only a short moment, he still saw clearly that the word "Crown Prince" was on the other party's gold medal. The expression on his face also changed from anger to surprise, "You, were you sent by the prince? But yesterday......"

Before he could speak, Li Wei waved his hand and interrupted him, "Yesterday it was the prince's guard chief Yu Ping, he was the bright sword, and I was the dark sword, do you understand?"

"So that's how it is." Although Li Wei was dressed normally, he had a gold medal in the prince, which was not something that ordinary people could get. Lan Chuo was so disdainful that he couldn't help but stand up and said in awe: "Sir, your surname is yours."

"Young Master Lan is polite. My surname is Zhang, the prince's aide, came to the matter of losing the letter."

When talking about the loss of letters, Lan Chuo showed a look of shame on his face. He sighed slightly and said, "We are all from my hometown for more than ten years, and I never thought we would do such a thing."

"Young Master might as well tell me in detail about the story of losing the letter."

"The incident happened half a month ago. I received an urgent order from my father, ordering me to classify and number all his correspondence within three days, and all the important letters were destroyed. My father had thousands of letters in the past ten years, and he had no choice but to destroy them all. I thought that it was too late to find some old people to help number them and found 125 letters with more confidential content. When I was about to destroy them on the afternoon of the third day, I found that there were only 124 letters, one missing. I ordered people to search, but found that one of the family members who participated in the division of the letter disappeared the night before yesterday. I dared not hide it, so I immediately reported to my father with a pigeon letter."

"Then what is the content of this stolen letter?" Li Weizheng asked again.

"This letter was read by the missing family at that time. He reported it to me, but I couldn't remember it clearly, and I only vaguely remember it related to the prince."

"Does Mr. Lan have his specific address?"

"Yes, this person is named Yan Shi, and he is from Huangzhou Prefecture, Huguang. I have his specific address. Yesterday I gave it to Yu Qianhu, and Yu Qianhu immediately set out to Huguang."

Li Weizheng lowered his head and thoughtlessly. Yu Ping immediately went to the old house to pursue him, but he felt that Yu Ping was still a little hasty. What should he do if this person did not return to his hometown but hid in the capital? However, the prince sent him here, perhaps just to supplement Yu Ping's flaws that were more than wise but not enough. Thinking of this, Li Weizheng said: "Can Mr. Lan take me to see where the letters are sorted out?"

Lan Chuo nodded and stood up and said, "Please come with me, Mr. Zhang."

The place where the letters were sorted was in Lan Yu's study room. Because the letter was lost, it was still the same. The room was clean and the doors and windows were closed. It was just that the air in early spring was humid, which made the room feel a faint smell of musty smell.

"We are sorting out letters here, and there are seven people in total." Lan Chuo pointed to a chair beside the window, "The family member named Yan was sitting there at that time."

When he entered the door just now, Li Weizheng discovered that this place was not an inner house. It was very close to the main hall and it was easy to climb into the window. He smiled and asked, "What do you mean is that this letter was stolen after being entrusted, right!"

"That's right. In fact, when I was counting the last one hundred and twenty-five letters, I accidentally discovered that the number of one of the letters was not mine when I was about to destroy them. Then I realized that someone had lost the bag. This person was very scheming, remembered the number, and went into the study at night to change the letter."

Li Weizheng nodded. It was true. The family surnamed Yan was not only scheming, but also very rational. He had all 125 confidential letters together, and he didn't move anything else, but he took the letter he liked. From this, it is unlikely that this person would hide back to his hometown honestly. However, if he hid somewhere else, he would need money and should borrow money from the people in the mansion.

Thinking of this, Li Weizheng asked again: "Have he asked other people that had borrowed money or stole valuable things in the mansion?"

"This..." Lan Chuo was a little difficult to open his mouth, so he finally took out a beautifully crafted jade Pixiu from the bookcase and said helplessly: "Yes, he asked another family member who had a close relationship and borrowed twenty coins of money and stole the other of the pair of jade Pixiu in the study. This is my father's beloved thing. I really don't know how to explain it to my father."

Sure enough, he had the intention of hiding, but this family member named Yan stole the jade Pixiu Li Weizheng, but he was concerned about asking another family member who borrowed twenty guan. Twenty guan was definitely not a small number for a servant. If he had no promise, who would lend it?

He suddenly found the clue and asked excitedly: "Where is this family member who borrowed money? Bring him to see me quickly."

Lan Chuo replied with a frustrated look on his face: "He also disappeared, and disappeared the next day after Yan Shi disappeared. He once told people that he regretted lending money to his family surnamed Yan and wanted to recover the money. He did not say where to pursue it."

Li Wei was stunned for a moment, then disappointment poured into his heart. The clue he had just discovered was cut off again, "Then why didn't you say that the two were missing in the letter?" He suddenly asked with some dissatisfaction.

Lan Chuo shook his head and said carelessly: "He is not a stolen person, so it's meaningless to say he is."

Li Wei was stunned and stared at him for a long time. As the saying goes, like a father, he will have a son. Is Lan Yu so stupid?

Li Weizheng was in a heavy mood. Now things are clear. The family member named Yan Shi must have been hiding. He was looking for an opportunity to report Lan Yu to seek credit. Another family member was gone. The only clue now is the jade Pixiu on his body. Li Weizheng couldn't help but hold the jade Pixiu in his palm and looked at it carefully. It was indeed the best jade, gentle and delicate, with the name of Lan Yu engraved on the bottom of his feet. He sighed and put down the jade Pixiu, and his wealth was not revealed. The Ming Dynasty was so great that he went to find the other jade Pixiu?

Several people walked into the yard, and Li Wei was bowing and said, "Disturbating Mr. Lan, I'll find another way!"

"I'm so sorry, I can't provide you with useful clues, Mr. Zhang, please!" Lan Chuo waved his hand and prepared to see off the guests.

Just as Li Wei was turning around, suddenly, he seemed to have discovered something?
