"This is indeed the tub of our inn, right."

The shopkeeper and his wife nodded affirmatively after going up to check it out.

"Is there any difference between the bath bucket that Master Yuan used that night and this bath bucket?"

Lu Yanqing continued to ask, this kind of thing must be said by the person concerned to be more convincing.

"These tubs are all made to the same specifications by the same master, so they are no different."

"Okay, I'm tired, please step aside, if nothing else, your inn will be able to reopen tomorrow."

After getting his satisfactory answer, the corners of Lu Yanqing's mouth pulled out a faint smile, and he didn't forget to comfort the shopkeeper and his wife.

Hearing this, the shopkeeper and his wife smiled and hurriedly thanked Lu Yanqing, and then retreated to the position where they had just stood.

"Since this bath bucket is no different from the bath bucket that Master Yuan used that night, then I should have no opinion on using this bath bucket to demonstrate the murderer's criminal process, right?"

Lu Yanchao asked everyone that every step he was going to take next must be convinced by everyone present, and he could not leave the slightest room for the prisoner to quibble after solving the case.

"No, go ahead."

Yang Chenghuai said in a deep voice, by observing the expressions of Jiang Xiangchun and Feng Luan, he vaguely sensed that something seemed to be wrong.

But before there was conclusive evidence to identify the murderer, he still looked at Jiang Xiangchun.

After all, this is the widow of his best friend, how can he watch Jiang Xiangchun being bullied for no reason.

After getting Yang Chenghuai's approval, Lu Yanqing said in a deep way outside the hall: "Bring the hot water!" ”

As soon as the words fell, I saw a row of officials each carrying two buckets of hot water into the hall, pouring the hot water into the tub in one go, and after a while, the bathtub was filled with eighty percent of the hot water.

"Alright, you can come forward."

With Lu Yanqing's greeting, everyone gathered around the bathtub to see what kind of reputation Lu Yanqing wanted to make.

After seeing Yang Chenghuai, a heavyweight, fall into place, Lu Yanqing officially started his performance.

I saw Lu Yanqing open the stopper of the porcelain bottle and pour the alum oil inside into the bath barrel.

This alum oil has no color, but it is accompanied by this very pungent smell, looking at the purity of this green gong oil, it is okay, and it disappears in an instant after submerging in the water.

After standing for a while, I saw that the water in the tub gradually turned a faint light blue, which is not easy to detect if you don't distinguish it carefully.

"Is the water turning blue?" Ge Changwu said with some uncertainty.

Guo Xiande bowed slightly, "It seems to have indeed turned blue." ”

Several officials on the side also chimed in.

"What's going on? How can alum oil be diluted in water and be blue? Ge Changwu looked at Lu Yanqing very puzzled, as the initiator of this matter, he thought that Lu Yanqing would know something.

Lu Yanqing did not hesitate to explain, chuckled lightly and pretended to be mysterious: "Normally, green alum oil dripping into the water does not make the water blue, but at this time, this green gong oil is dripping in this bath bucket." ”

"Does it make a difference?" Yang Chenghuai asked out loud with a frown, he didn't notice what the mystery was.

"There is a difference, naturally." Lu Yanqing bowed slightly, then pointed to the water and said, "Lord Yang, what is the difference between the bath bucket you look at and the bath bucket used by ordinary people?" ”

Hearing this, Yang Chenghuai squinted his eyes and looked into the bath bucket, and only after half a ring did he realize the problem, "How can I look at how a piece protrudes from the wall of this tube?" ”

"That's right, that raised position is really a copper skin embedded in the wall and bottom of the cylinder."

Lu Yanqing didn't have ink, so he answered directly.

"Yes, it is indeed copper, in order to make this bath barrel stronger and more durable, I specially asked the master who made the bath bucket to inlay copper skin on the wall and bottom of the bath barrel."

The shopkeeper explained the reason why he embedded the copper skin.

"So that means that this green gong oil dripped into the water and turned the water blue, is it because of this copper skin?"

According to the words of Lu Yanqing and the shopkeeper, Yang Chenghuai made inferences.

"That's right, Lord Yang, you are really intelligent, and this water turning blue is related to this copper skin."

Taking advantage of this opportunity, Lu Yanqing slapped a sycophant, and everyone hurriedly echoed when they heard this.

This is the highest-ranking official that Lu Yanqing has come into contact with so far, although this Yinqing Guanglu doctor is only a loose official, but his network in the court is solid.

Now that there is a chance to let himself fill the cup in front of Yang Chenghuai, Lu Yanqing will naturally not give up this almost, and he must take the opportunity with Yang Chenghuai well, maybe it will be of great use in the future.

Yang Chenghuai, who is so sought after by everyone, is a little fluttering in his heart, and it seems that he still has to walk around outside Chu Jing more.

In that Chu Jingcheng, which is full of powerful people, although he can talk to anyone, he is a loose official, but it is somewhat difficult to flatter people, who doesn't want to be sought after by tens of thousands of people?

"Then what does this have to do with Brother Yuan's death?" Yang Chenghuai reintroduced the topic.

"Lord Yang, don't be anxious, a good show is about to be staged." As he spoke, Lu Yanqing shouted outside the public hall again: "Lift the pig up!" ”

As soon as Lu Yanqing's words fell, he saw a servant carrying a piglet tied up with five flowers into the public hall.

"You're going to use a pig demonstration?" Yang Chenghuai pointed to the piglet in the hand of the servant, with a look of displeasure on his face.

After all, the deceased was his best friend, and this kind of demonstration with a pig is somewhat insulting.

Looking at Yang Chenghuai's reaction, Lu Yanqing immediately realized that there was something wrong with it, and hurriedly apologized: "Lord Yang, the villain is also helpless, you can't use a living person to demonstrate, right?" ”

Jiang Xiangchun grabbed the handle in Lu Yanqing's words and scolded sharply: "What do you mean by this? Why can't it be demonstrated with a living person? Can this pig be compared to my family? Lord Yang, you want to be the master of the slave family, my master is still humiliated by this kid when he dies, woo woo, the slave family ......"

Before Jiang Xiangchun could finish complaining, he heard a crisp sound of "pop" coming from the side, interrupting Jiang Xiangchun's words.

"Adult, kid is also unintentional, kid is wrong, kid is wrong......"

As he spoke, Lu Yanqing kept slapping himself, and everyone was stunned when he heard the crisp sound.

"Okay, okay, I think you're also eager to solve the case, forget it this time."

Yang Chenghuai admires Lu Yanqing, a young man, very much, even if he thinks about the sycophants just now, Yang Chenghuai is not easy to delve into.

"What? Lord Yang, how can you just forget it? This kid is clearly insulting my husband! ”

Jiang Xiangchun originally wanted to use Yang Chenghuai's hand to convict Lu Yanqing, but after she saw Lu Yanqing's previous series of actions, Jiang Xiangchun was really panicked.

"Don't be vexatious here, if you want to know how Brother Yuan died, give me a little peace!"

Yang Chenghuai looked annoyed, and admonished in a slightly majestic tone.

When Jiang Xiangchun heard this, he dared to say anything, so he could only stay timidly and not make a sound.

"Boy, isn't it a bit too rigorous to demonstrate with pigs? After all, there is still a clear difference between pigs and people. ”

Yang Chenghuai suggested loudly, so as not to criticize afterwards.

Lu Yanqing had already thought about this, but what could he do about it, so he could only throw this question to Yang Chenghuai with a wry smile: "My lord, the kid can't do anything about it, I can only make do with it and buy a pig back for a demonstration, and this pig also cost me a month's salary, and I can only borrow money to live this month." ”

Lu Yanqing pretended to be pitiful and shook his head in frustration.

Yang Chenghuai thought for a moment and asked in a deep voice: "Are there any prisoners in the prison who have been sentenced to death?" ”

Hearing this, Guo Xiande hurriedly responded, "Yes, yes, but there is no date of execution." ”

"It's okay, I'll let this kid demonstrate."

"Lord Yang, isn't this not very bereological?"

"I'll escalate it, you don't need to worry."

Since Yang Chenghuai said so, Guo Xiande didn't ink anymore, and after glancing at the official on the side, the official walked towards the outside of the hall in a hurry.

A short time later, the official escorted a middle-aged man in prison uniform into the hall.

Lu Yanqing had some impressions of this middle-aged man, half a year ago, he had raped and killed more than ten old and weak women and children in Yongan County, which can be described as a heinous person, and was later caught by Lu Yanqing and Ge Changwu, and was ready to execute the punishment of car splitting in public after the autumn, so that he could die in this bathtub It was somewhat cheap for him.

Before coming, the official had tied up this man, and his mouth was sealed with a rag, so he could only struggle with a whimper, but he couldn't escape the restraint at all.

At the suggestion of Guo Xiande and Yang Chenghuai, several officials threw it into the bath bucket.

When the prisoner saw that the servant had prepared a bucket of hot water for himself to bathe, he was immediately happy, and he played with water in the tub very arrogantly, and after half a sound, he leaned on the wall of the tube and stopped tossing, but he did not know that danger was quietly coming.

The onlookers didn't care about this, it would take some time for this prisoner to die in the bath barrel, so Lu Yanqing took advantage of this gap to inquire loudly: "Miss Xichun, may I ask if Master Yuan takes a bath for more than two quarters of an hour every time?" ”

Xichun was slightly stunned when he heard this, and then nodded slightly: "That's right, every time the master takes a bath, it is indeed more than two quarters of an hour, and the master does not have many hobbies, so taking a bath is one." ”

"Then what is your master's posture when he takes a bath?"

"Posture in the bath? The old man seems to like to lean against the wall of the barrel and spread his arms outside the tub. ”

Xichun said as he gestured towards Lu Yanqing.

"Thank you Miss Xichun for telling me." Lu Yanqing smiled kindly, knowing that these were enough.

At this moment, the prisoner in the bathtub suddenly made a whining sound, and everyone hurried to look at it.

I saw that the prisoner's face at this time was pale, his pupils were round, and his face was frightened.

Seeing this, Lu Yanqing's expression froze, and he hurriedly spoke: "Untie the rope on his body!" ”

When the official heard this, he hurriedly did so, and Lu Yanqing easily pulled out the rag from the prisoner's mouth, but the prisoner at this time shocked everyone......
