After questioning the two, Lu Chengqing fell into deep thought: Master Cui is a member of the three grades of the current dynasty, he is an honest official, he is kind, and there is no party in the court, so he will not be a political enemy. Because Caiyun and Lai Guogong had a dispute, they should have something to do with Lai Guogong. But how do you go about investigating?

Qin Xuan also secretly slandered himself on the side: From Cui Kelai's words, it can be concluded that the murderer must be familiar with Master Cui. Otherwise, there wouldn't have been a single shout! As for Du Wei, he must go to investigate no matter what, after all, according to the clues at the moment, he is the most suspicious......

After a while, Lu Chengqing came back to his senses, looked at the servants, the officials and Qin Xuan one by one, and asked, "What do you think of this case?" ”

When Qin Xuan heard Lu Chengqing's words, he scolded in his heart: I'll go, after thinking about it for a long time, you have to come up with such a sentence! Shaking his head slightly, he said: "Lord Qiyu, according to his humble position, Lai Guogong is suspected, so he should ask about it." If Lai Guogong is framed, it will help him clear his suspicion! ”

When Lu Chengqing heard this, a smile appeared on his face, and he said in his heart: This son's words are really clever! Just saying this sentence to clear suspicion will not make me offend Lai Guogong! Nodding with satisfaction, he asked again, "Well, that's good!" Is there anything else you would like to say? ”

Qin Xuan's tone was still calm, and he said slowly: "Fang Cai, I have asked Cui Kelai, a subordinate of Cui Mansion, and I learned that Cui Mansion was as usual last night, and there was no sound from the study. From this point of view, the murderer must have an old relationship with Master Cui! ”

After Qin Xuan finished speaking, Lu Chengqing nodded slightly, and echoed: "Yes, this official also thinks the same!" ”

Qin Xuan secretly said in his heart: Hmph, you think so too? Then why don't you say it, don't pretend to die! Mixed with a trace of disdain, he swept past Lu Chengqing and did not say anything more.

Lu Chengqing saw that Qin Xuan and the three of them didn't say anything again, so he blurted out: "Pingkang Fangzheng's words are consistent with this official, so he will go to Du Mansion with this official!" You two are here, continue to investigate carefully, and don't let go of the slightest! After speaking, without waiting for the three of them to reply, they turned around and left.

When Qin Xuan heard this, he reluctantly took steps to follow......

Lai Guogong, who is known as Du Ruhui, who is known as "Fang Mou Du Xuan", died of serious illness in Zhenguan for four years. His eldest son, Du Go, inherited the title of Duke of Laiguo.

Walking to the gatehouse of Dufu, Qin Xuan couldn't help but sigh with emotion: What is a mansion, this is! Look at the gatehouse of the people, the carving is exquisite, the door wall is tall, above the Zhu door, there is a door plaque hanging in the middle, the two big characters "Du Fu" on it, the momentum is magnificent, and a rich and noble atmosphere arises spontaneously......

When the janitor saw a few people, he stepped forward with a smile and asked, "How many adults, I don't know what you are doing?" ”

Lu Chengqing smiled slightly, and replied: "This official Lu Chengqing is investigating the case of the death of the imperial historian Cui Wenliang, and found that there are clues pointing to Lai Guogong, I have come to find out, and please spread the word!" ”

As soon as the janitor heard that his master was suspected of murder, he frowned slightly, and was stunned for a long time before he came back to his senses and said: "Later, the little one will enter the house and spread the word!" ”

It didn't take long for Qin Xuan and the others to be invited in. Bypassing a delicate shadow wall, you will come to the courtyard, the whole courtyard, square bricks, clean and spacious. There are five main rooms, which are beautiful and majestic, and there is a row of side rooms in the east and west, which is symmetrical.

After walking dozens of steps, he walked to the door of the hall, Lu Chengqing stopped, sorted out his clothes up and down, and then continued to walk into the hall.

Hearing that her son was suspected of murder, Mrs. Du was sitting in a precarious position in the middle of the hall. Beside him stood a somewhat delicate maid, smiling slightly. Across the wooden table, opposite sat Du Wei, who inherited the title of Duke of Laiguo.

Seeing this, Qin Xuan couldn't help but sigh in his heart: It is also the founder of the Tang Dynasty, and he is also Li Shimin's trusted right-hand man, why is the Du family's mansion so luxurious, but the mansion is a little inferior! Could it be that Li Shimin prefers Du Ruhui?

Du Gou is also a doctor of the imperial history, and there is a knighthood in his body, Lu Chengqing walked into the hall, and he bowed his hand and said: "Xiaguan Lu Chengqing, I have seen Duke Du and Mrs. Du!" ”

Seeing this, Qin Xuan hurriedly followed suit, raised his hand to give a salute, and said, "Humble Qin Xuan, I have seen Duke Du, I have seen Old Lady Du!" ”

Before Du Wei could speak, Mrs. Du said slowly: "No need to be polite! Listening to the words of the people of the Mansion, Lord Lu came this time because Go'er was suspected of the death of Lord Cui? ”

Lu Chengqing got up, bowed his head slightly, and said in a calm tone: "Yes, after investigating for a long time, the lower officials found that there were many clues pointing directly to Du Gong, so they came to understand some information in order to clear Du Gong's suspicion!" ”

Lu Chengqing's words made Du Wei very satisfied, smiled slightly, nodded and said: "Well, if Lord Lu has anything you want to know, just open your mouth, I should tell you the truth!" ”

Lu Chengqing saw that Du Gou's face was gentle and he spoke kindly, and finally let go of his heart. "I don't know where Du Gong was last night, have you ever been to Pingkanglifang?"

When Du Wei heard this, he was slightly stunned and hesitated: "This ...... I was indeed at Ping Hong Lane yesterday! ”

When Qin Xuan heard this, he was immediately a little stunned, and said secretly in his heart: No, is it really him? But if it was him, why did he admit it so easily? Is it pretending to be deep, or is it real? For a moment, Qin Xuan was a little confused.

Lu Chengqing was also very puzzled, raised his head and stared at Du Gou for a long time, before he came to his senses and asked softly, "That'...... Where was Du Gong last night? Are there witnesses? ”

Du Gou's face stiffened slightly, and after a while, he said, "Yesterday I was in the Caiyun Room of Huancai Pavilion!" Maybe I drank too much wine, and before I could get drunk, I fell there, and when I woke up, it was already the end of the day! ”

Qin Xuan unconsciously frowned slightly, and there was a scorn in his heart: Drinking too much? That's a bit far-fetched! Now the clues involve you and Caiyun in total, and both of you have drunk too much and testify to each other, isn't it a bit inappropriate?

Lu Chengqing wanted to ask again, but Du Wei was already a little displeased, and blurted out directly: "Okay, if Lord Lu still has questions, you can go to Huancai Pavilion to investigate, please go back!" ”

Du Gou gave the order to expel the guest, and Lu Chengqing couldn't say anything more, so he laughed a few times, and bowed his hand and said, "Then the next official will leave!" ”

Out of the Du Mansion, Lu Chengqing's face was extremely ugly, he stretched out his hand and pointed at Qin Xuan, and said lightly: "Look, Du Gong is still angry!" ”

When Qin Xuan heard this, his heart moved: I'll go, don't you think so too, is it my fault that I bring it up? Trying to squeeze out a smile, he bowed his head and said, "It's come to this, don't be angry!" At least we know that Du Gong was indeed in Pingkangli Square yesterday, and he also clarified the next target of the investigation. Besides, the reason why Du Gong was a little unhappy was because spending the night in the Qinglou Song Workshop was not a glorious thing! ”

Lu Chengqing thought for a moment and snorted coldly. "Hmph, do you still need you to teach the official?" After saying that, he brushed his sleeves and left. Qin Xuan shook his head and followed helplessly.

Walking into the Huancai Pavilion, Qin Xuan looked around, and his first feeling was that it was big, much larger than Huaixiang Building. Many people in the hall were drinking and recreational, and when they saw Lu Chengqing coming in an official robe, they whispered.

"Hey, who is this man? Wear the official mansion and come to the Qinglou Song Workshop! ”

"Who knows, maybe I'm a little anxious! Haha-"

"Shhh

Hearing everyone's discussions, Qin Xuan moved half a step to the side slightly, putting on a "I don't know him" appearance.

Lu Chengqing, who is extremely eye-catching, naturally attracted the attention of the courtesans of the Qinglou. I saw a woman with flowers and branches and heavy makeup, who stepped forward diligently and said coquettishly: "Yo, this adult, please come in quickly!" ”

Lu Chengqing seemed to be a little unhappy, waved his hand at the woman and shouted, "Go, go, call your mother!" ”

The woman was taken aback, and instantly made a straight face, pouted, stomped her foot slightly, turned around and left, and muttered softly: "What's the big deal, you may not be able to do it when you get to bed!" ”

When Lu Chengqing heard this, his face turned blue. Qin Xuan smiled secretly in his heart: That's it, maybe it's not good, girl, you really have eyesight!

After a while, a woman with a bright face came up with a smile. "Yo, what's the big man angry about? As long as you enter our Huancai Pavilion, you will be happy immediately! ”

Lu Chengqing obviously didn't eat this, and said coldly: "Take me to find Caiyun!" ”

The woman was slightly stunned, then her eyes rolled, and she sighed: "Ouch, I said my lord, Caiyun is picking up customers at the moment, look, why don't I find you a new one?" In addition to the colorful clouds, there are also clouds and flowing clouds, all of which are spiritual! ”

Lu Chengqing pouted and frowned. "This official is here for Caiyun today, hurry up and lead the way, don't be noisy!"

The woman's face was embarrassed, and she replied pitifully: "My lord, Caiyun is picking up customers, or ...... Are you waiting a bit? ”

Lu Chengqing stared at the old bustard, and said sharply: "This official is investigating the case, how can there be any reason to wait!" ”

The woman bowed her head slightly, and said nothing.

Lu Chengqing frowned and scolded: "What are you talking about, take this official to Caiyun's room!" ”

The old bustard still didn't move, and a weak "this-" came out of his mouth softly.

Lu Chengqing stared, his face trembled slightly, and he gritted his teeth and said, "What is this!" Hurry up! ”

The old bustard hesitated for a moment, and finally couldn't resist Lu Chengqing's murderous gaze, and reluctantly moved his steps.

Qin Xuan followed Lu Chengqing and walked down the stairs to the second floor. Walking in the corridor on the second floor, in the room next to him, there were coquettish moans from time to time, and faint ** sounds, one after another, endlessly, Qin Xuan was a little thoughtful.

After dozens of steps, he finally came to the door of Caiyun's room. Unlike the other rooms, the Caiyun room is quiet, not at all like picking up guests. Madame stretched out her hand and crept away.

Seeing this, Lu Chengqing snorted very disdainfully, and then pushed the door in. Taking a step forward, Lu Chengqing, who had just raised his head, was stunned in place and did not move for a long time. Qin Xuan stepped forward curiously and looked into the room, and his eyes suddenly became bossed.
