I am the cook, but I am Li Er's son-in-law

Although there is only one word difference between tung oil and kerosene, their functions are very different.

Kerosene...that's fuel.

Li Shimin took a few steps forward, stared at Zhou Xiaosan cautiously, and said in surprise, "Are you sure?"

Zhou Xiaosan nodded: "I have done many experiments. In the past few days, the building materials used in public schools in various places have been tested, and most of them are soaked in kerosene."

"It's easy to burn with a fire."

Zhou Xiaosan didn't talk about other problems, but simply introduced the problem he discovered.

A few short sentences silenced the atmosphere of the entire court.

This question...is really too big.

what does that mean?It means that the entire Ministry of Industry is no longer under the control of the imperial court and His Majesty. They are listening to other people's opinions and doing things that are contrary to the imperial court's decree.

Li Shimin didn't speak, frowned, and looked at the people from the Ministry of Industry seriously.

The matter of building materials is handled by the Ministry of Industry.But Lu Yigong from the Ministry of Industry is one of his own, and has always been respectful to Yin Xuan. Such a person will work for the family?

If it is true, then the look in the eyes of himself and Yin Xuan is not too bad?
Lu Yigong was stupefied by the news, and was stunned for a while, then he was pushed by Li Tai at the side, and then he came back to his senses, staggered out of the queue in two or three steps, and knelt down with a bang: "Your Majesty, minister... minister... The minister doesn't know about this."

As soon as he said this, he immediately regretted it.

This is admitting the fault of one's oversight.

"I will immediately investigate this matter, and give an explanation to His Majesty, the imperial court, and the public school." He hastily added another sentence to show his loyalty.

Li Shimin turned his head to look at Zhou Xiaosan: "Mr. Zhou, this matter... What clues can you investigate?"

Zhou Xiaosan said hastily: "I dare not do things that go beyond my pedestal."

As it was related to the Ministry of Industry, it was not something that a mere doctor like him could investigate. According to the laws of the Tang Dynasty, Dali Temple would be responsible for matters involving officials of the seventh rank or higher.

Sun Fujia bowed out and said: "Dali Temple will definitely be thoroughly investigated."

Li Shimin didn't speak, but just looked at Sun Fujia indifferently - he was very reassured about this person, but he was only a young minister after all, and there was a minister of Dali Temple above him.

Dali Siqing is from the Pei family in Hedong.

Li Shimin was not afraid that they would dare to obey others, but Li Shimin was somewhat worried that these people would delay time.

He pondered for a while, then said softly: "This matter... I will leave it to Zhou Langzhong. He has already investigated some clues, so there is no need to hand it over."

Sun Fujia has no objection.

Dali Siqing didn't stand up either.

This made Li Shimin a little surprised. He thought that the aristocratic family would try their best to take this matter into his own hands, but did they accept it so smoothly?
No resistance at all?
Zhou Xiaosan also felt that something was wrong, agreed, and retreated to the queue, thinking about how to investigate this case.

Lu Yigong also bowed back, and the cold sweat on his forehead couldn't stop dripping down.

How long have you been a minister?It was unlucky that such a big event would happen, and he still hoped that he could stay in this position until he enjoyed his old age.

Now it seems that if I can guarantee not to lose my head, it is a lucky thing.

The meeting is over.

People from several aristocratic families walked out of the palace gate and gathered together, talking and laughing.

"This... Zhou Xiaosan is really sharp enough." The Wang family sneered and waved their hands, "I didn't expect him to find out this matter so quickly. He is really a good dog."

"Your Majesty, it's really troublesome to use it smoothly." The Cui family shook their heads and sighed, "Unfortunately, this dog can't be beaten for the time being."

The people in the court, especially the aristocratic family, have always looked down upon Zhou Xiaosan - he was born too poor and humble, so he has so many abilities, but he has never spent a serious day studying.

It is already a great blessing for such a person to enter the court and become an official.

Isn't it just a hound that was rewarded by His Majesty?
"Let him investigate." The Wang family waved their hands and sneered, "I really hope he can find out those things sooner."

They were not afraid that Zhou Xiaosan would find out something, or in other words, they hoped that Zhou Xiaosan would find out something.

On the prince's house.

Li Chengqian quickly invited the Cui family over.

"That Zhou Langzhong investigated the case so quickly." Li Chengqian frowned, and asked anxiously, "Will he find out about that matter?"

The Cui family vowed: "Don't worry, Your Highness, we have already explained the people you arranged to go there, and we will never leak this information."

"Really?" Li Chengqian was worried and asked again.

The Cui family members nodded seriously, as if they were telling the truth: "Please rest assured, Your Highness."

Li Chengqian waved his hand, and carefully instructed: "You guys should do it better."

The Cui family should come here.

He turned around and left the Prince's Mansion, and went straight to Pingkangfang.

Just when the Cui family was letting loose, Lu Yigong took Zhou Xiaosan to the Ministry of Industry, trembling, and he still couldn't figure out why such a thing happened.

The matter of building materials is under the Ministry of Industry's Department of Industry.

Langzhong is an honest man, about fifty years old, looks simple and honest, his surname is Fan, and he can barely be regarded as a family origin, just a collateral line.

What happened in the court hall scared him so much that he could hardly take care of himself.

Following Lu Yigong and the others, when they arrived at the Ministry of Industry, they called all the craftsmen in charge of processing building materials over.There is one Yuanwailang, three principals, and some other large and small craftsmen.

They are not qualified to participate in the court meeting, and they are still a little unclear when they are called here.

Say hello to Shangshu and Langzhong one by one.

Then they turned their heads to look at Zhou Xiaosan, this very strange face.

Zhou Xiaosan didn't speak, just looked at Lu Yigong.

Lu Yigong nodded gratefully towards him, and said in a cold voice: "There are some problems with the building materials supplied by the Ministry of Industry to public schools. Do any of you know what's going on?"

Yuanwailang looked confused: "Shangshu, those building materials are all high-quality pine wood, how could there be any problems."

The master and craftsmen lowered their heads.

"It's not tung oil that's used to soak the wood, it's kerosene."

With just one sentence, Yuanwailang was so frightened that he broke out in a cold sweat, and his expression was almost exactly the same as that of Lu Yigong in the court hall.

With kerosene?
Is this because he is afraid that he will not catch fire?

"Who did this thing, stand up yourself." Lu Yigong squinted at them, then pointed at Zhou Xiaosan, "This is the famous detective in Chang'an, Zhou Langzhong, you should have heard of his reputation of."
