Xu Jingzong's words were a bit complicated. After listening to them, Li Su sorted them out for a long time before he understood what the words meant...

To put it bluntly, the reason why Yang Yan was in the Firearm Bureau was that he had a backstage, and his backstage was an amazing man. Changsun Wuji, who was also a minister of the Ministry of Personnel, gave Yang Yan so much power, so in order for everyone to continue to be smooth in the officialdom in the future, he could not beat this guy even if he had a temper.

Li Su was secretly surprised. He didn't expect that Yang Yan's backstage was so big. The unspoken rules of investment banking papers these days. Which powerful family has accepted the business papers? This person is the subordinate of the powerful family. Yang Yan recognized it accurately and actually joined Changsun Wuji's mansion. Changsun Wuji actually accepted his business papers.

Whether it is a clerk or a clan force, Yang Yan’s background is not simple.

Of course, Yang Yan is not the name "partners" that Yang Yan becomes a bad person. The bad person does not have the courage to point at the emperor's nose and scold him very much. Those who are officials in the court can never simply define him as good people or bad people.

Li Su naturally didn't have the courage to fight with the Changsun family. He was also named a lord and was particularly favored by Li Shimin, but it does not mean that Li Su had a gold medal for avoiding death. If Changsun Wuji wanted to kill him, a young man in his teenage years, it would be as easy as killing a bed bug... a cute little rabbit.

It was very troubled. The head of the Tanghunter Bureau monitored the firearms bureau and became afraid of a subordinate who was two levels lower than him. Li Su suddenly felt like his hands and feet were bound, which was very unhappy.

"Get him! Why don't you suck him?" Li Su stared at Xu Jingzong angrily and expectantly: "Go and suck him, think it's my authorization."

"Ah? This..." Xu Jingzong's face turned pale and he couldn't speak for a while. Obviously, Lao Xu didn't have the courage either.

Li Su was very disappointed with him. Bad people were bad people. He could not expect him to be afraid of power.

His tone was not very kind, Li Su glared at Xu Jingzong and said angrily: "Why don't you dare to suck him to me?"

Xu Jingzong smiled at him awkwardly.

Li Su immediately understood his smile.

Just like his thoughts, Xu Jingzong was also strongly looking forward to Li Su going to draw Yang Yan...

Scheming bitch!

************************************************************

The firearms bureau was busy all day, and it was almost evening. Li Su packed up the house. He went out to visit King Li Ke of Wu. The poor child was still staying in the tent and did not dare to move. He was all over the tent to eat, drink, defecation and urination. His face became paler. I don’t know if it was scared or because I didn’t see the sun for two days.

Li Su sincerely felt sympathy for him, and at the same time he became more and more awe of the palace of the Tang Dynasty.

A trivial matter that seemed to him was a trivial thing that scared a prince to be so virtuous. The imperial power of the Tang Dynasty was like a piece of burnt red charcoal, and anyone was hot. In the Xuanwu Gate Incident, Li Shimin killed his brother and brother. After eleven years, the haze in his heart still could not be dispersed, so everything related to imperial power became his forbidden body, and no one was allowed to touch it, because this was something he exchanged for after giving the bad reputation of killing... It was as precious as his first love.

…………

The next day, Li Sugang stepped into the firearms gate and things came.

Another supervisor of the Firearms Bureau, Chen Tang, found Li Su uneasy and reported something.

After Li Su prepared gunpowder the day before yesterday, Xu Jingzong ordered people to weigh it. Li Su and Xu Jingzong calculated that they could create about 400 thunders, so Xu Jingzong gave instructions to the craftsmen that 400 thunders must be made with quality and quantity.

"Quality and quantity" means. The quality must be good. If it is lit, it can kill people if it is thrown out. Moreover, the quantity must be just right, not less or too much.

Gunpowder is stuffed into a small pot. How much can it fill can produce lethality? Li Su had calculated accurately when he was in Songzhou. Too much gunpowder in the pot is not good. If it is too powerful, it will kill his soldiers on the side by mistake. If it is too little gunpowder, it cannot be called a thunder. At most, it is a big firecracker. It has no lethality except to hear a sound.

But what Chen Tang reported was a bit ridiculous. Last night, Yang Yan changed the production plan without authorization. The same amount of gunpowder actually asked the craftsmen to create 800 thunders, which doubled.

After hearing this, Li Su wanted to laugh. The original intention of serving the country was good and worthy of praise. Everyone hoped that the soldiers of the Tang Dynasty could get more thunders to open up territory for His Majesty, but they did the wrong thing. They could only make 400 gunpowder and turn it into 800. What Li Shimin got would not be thunders, but 800 firecrackers. It would be impossible to expect them to conquer cities and break up villages. Marriage and funerals could come in handy...

"Is it Yang Jiancheng's idea?" Li Su asked with a frown.

Chen Tang lowered his head and said respectfully: "Yes, but the lower officials were unable to determine whether they would create waste products after reducing the amount of gunpowder, so he came to ask the sir."

Li Su's face turned a little dark: "Go and call Yang Jiancheng over."

Yang Yan came very slowly, and Li Su was late when he almost fell asleep in the room.

"I've met Li Jianzheng." Yang Yan bowed sloppyly.

Li Su reluctantly showed herself a kind smile: "Thank you for your hard work, please sit down."

"No, there are many things in the Firearms Bureau, so the officials have no time to sit down." Yang Yan refused to be tough, and there was a suspicion of criticizing the mulberry and scolding the gods.

Li Su's smile became a little stiff: "So, I'm straight to the point. I heard that Yang Jiancheng changed the number of thunders last night?"

Yang Yan nodded naturally: "The materials for gunpowder are very expensive, and they consume all the national treasury and people's fat. The officials believe that it is enough to create 800 pieces, so why does the surveillance officer only create 400 pieces?"

People with backstage cannot be offended, Li Su had to patiently explain: "The thunder of the sky was created by me. How much gunpowder should be filled in a thunder to be lethal to humans and animals? Only I know best. When the Battle of Songzhou, I had calculated accurately that the gunpowder in each thunder cannot be too much or less. Otherwise, it would be either a mistaken killing of his soldiers or useless waste. Yang Jiancheng changed the number to 800. Have you ever thought about how we explain to His Majesty if these 800 thunders could not hurt people at all?"

Yang Yan shook his head stubbornly: "The officials have seen the thunder of the sky. As long as they fill gunpowder, they will definitely hurt people. The officials think that 400 can hurt people, and 800 can also hurt people. If that is the case, why not make 800? The Master of the Superintendent is not in charge of the family and does not know that the firewood and rice are expensive. The Ministry of Revenue only allocates 4,000 silver coins this year, and it will cost most of the purchase of gunpowder materials and pottery jars. I heard that the Master of the Superintendent still intends to summon a few blacksmiths. In the future, the pottery jars will be converted into iron jars. In this way, the cost of the Firearm Bureau is even more difficult. Every article must be calculated. If you save as much as possible, it is also a good intention for the ministers to serve the emperor and the people."

Li Su smiled bitterly: "Yang Jiancheng is loyal, but... it is really a waste to make eight hundred thunders. If Yang Jiancheng doesn't believe it, why not let the craftsmen create one. Let's try the effect?"

"No need to try. Every time you try one, it will waste national treasury. Four hundred can hurt people, and eight hundred can definitely hurt people. The saying of how much gunpowder is ridiculous. Why does a drop of poison kill people? Why does it cost ten drops? The same is true for gunpowder."

Li Su took a deep breath. How could such a person reason with him? He was more difficult to deal with than Cheng Yaojin. Cheng Yaojin could at least show off an unreasonable face without any slap in others. However, Yang Yan showed off a reasonable face, but every word he said was a fallacy, and he was very stubborn and could not convince him at all.

Li Su is not very patient. Whether it is bad for the Firearm Bureau every day or leisurely living at home, he just wants to live less tiring. There is an additional Yang Yan in the Firearm Bureau. Li Su only feels that he has adjusted the difficulty of the game these days, and he has lived a very hard life.

"Yang Jiancheng, I think... you are really not suitable to stay in the firearm bureau." Li Su's smile gradually became cold, and his patience had been exhausted.

Yang Yan glared at his eyes, and an inexplicable aura appeared all over his body, and he sneered: "The lower officials are appointed by the Ministry of Personnel of the Secretariat. If Li Jianzheng wants to dismiss my official position, it may not be that easy."

"Your official, I won't give up, let's do this. You hand over the account books of the Firearms Bureau to Xu Jingzong. From today on, the account books of the Firearms Bureau, the civil servants and craftsmen, etc., will be decided by Xu Jingzong. Yang Jiancheng, you have a hard time. The school grounds and shooting ranges behind the Firearms Bureau are still being built, so I'll bother Yang Jiancheng to supervise the worker."

Yang Yan was stunned for a moment, then furious: "Li Su, do you want to underestimate me?"

Li Sudun felt funny: "I am the supervisor of the Firearms Bureau's big and small affairs. What is arranged by the officials to do? How can I underestimate the truth? Within the radius of the Firearms Bureau, all the power is mine."

"Don't say these empty words, I've seen it long ago. You are excluding dissidents and from then on, I'm the seventh-rank supervisor appointed by the Ministry of Personnel, a child with Huangkou. But I'm lucky enough to create gunpowder. How can I control the country's weapon?"

After arguing, this sentence finally revealed Yang Yan’s thoughts.

Yes, Yang Yan has always looked down on Li Su. He was not convinced by a teenage boy as his boss. He felt embarrassed. So from the first day of Li Su taking office, Yang Yan grabbed the power of all and big in the Firearms Bureau. Whether it is financial power or personnel appointments and removals, it was up to this seventh-rank supervisor to decide. When he meets Li Su on weekdays, he has a very indifferent attitude. These actions can be summarized in two words, "contempt".

Li Su is very easy-going and has never been concerned about the Firearms Bureau before. If someone is willing to take charge of the matter, he will naturally let him go. Anyway, no one has the courage to drive him, the supervisor whom His Majesty, off the stage.

However, today, at this moment, Li Su was finally angry. When he came to this era, he was cautious in everything as if walking on thin ice, but today he suddenly erupted like a long-silent volcano, and it was out of control.

"Yang Jiancheng, do you believe it or not? I, a yellow-mouthed boy, dare to slap you, and it slaps very heavily..." Li Su grinned at Yang Yan, revealing two rows of white teeth.
