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

There is also a reason for Wu Jue to be so anxious.

Regarding the bus, in fact, she had such an idea a long time ago, the public carriage, no matter how good the ox cart, it is a lot of income anyway.

However, Yin Xuan did not agree.

The reason is also very simple. Cows and horses are all living things. They excrete. If they are used as public transportation, it is inevitable that they will be dragged on the street, which is disgusting.

This is the most regrettable thing for Yin Xuan.

Pets are fine.

Just one huge downside, they have a sphincter and excrete biofertilizer.

Wu Jue doesn't care, he can make money, this small shortcoming can't be a shortcoming, besides, it's not very smelly, maybe it can make the court expropriate a few more official positions, which can be regarded as employment has been promoted.

嗏

What Fengchao says doesn't matter, she has to listen to Yin Xuan.

"Da Lang..." Wu Jue wanted to say something, but Yin Xuan picked up a chopstick of garlic shrimp and stuffed it into her mouth, muttering, she began to chew.

Although...she doesn't like Cantonese cuisine that much, but Dalang's cooking skills are really good.

She swallowed the shrimp and calmed down a bit: "Didn't Da Lang care about the bus?"

Yin Xuan peeled off the shell of the shrimp leisurely by himself, and nodded: "Don't be so anxious."

"On the other hand, Fengchao's side, how is the car research going?"

Wu Jue was taken aback, picked up a shrimp by himself, and peeled the shrimp shell with his head down, speaking not so confidently: "The testing machine has been made."

"But if it's on the road steadily, it's still a lot worse."

She felt a little guilty.

This sentence, in her opinion, is the beating of her own boss.

Yin Xuan asked casually again: "How is the research on internal combustion engines going?"

Wu Jue felt even more guilty, and her voice lowered a bit: "The stone grease is not enough, and there is hardly much progress."

Petroleum, that is, oil.

This thing is very rare now. There is no good mining method in the Western Regions, and the annual output is limited. Apart from being used as fuel, it has many uses.

All in all, its other usefulness is far more important than its use in fuel, so even less oil is allocated to the internal combustion engine.

This has led to the slow progress of the internal combustion engine. Scholars who study this area are cautious and tread on thin ice. A data has to be calculated repeatedly, for fear of wasting this pitiful share in their hands.

Although…

Their actions, in terms of results, have indeed been wasting oil.

"Then that's fine, nothing came out, so why are you in such a hurry." Yin Xuan smiled softly and shook his head.

Wu Jue muttered, "But now they're making money."

It took so long to take over Fengchao and Qianzhuang.

She has some bad habits of merchants to some extent.

Watching these enemies make money is more painful than losing money. Not only that, but the pain at this time is even more painful.

After all... This is a proposal that he once put forward. In Wu Jue's eyes, the money is not just as simple as they earned, but earned from himself.

"Earn." Yin Xuan said indifferently, "How much they earn now, will not be ours in the future."

"Have you calculated the cost?"

Wu Jue paused for a moment, didn't speak, just got up and went to the counter to fetch a pen and paper, and silently began to count.

Li Hui came over curiously and took a look.

She knows the numbers.

But... Those familiar symbols, function curves, and a lot of calculations still made her dizzy.

This…

Calculating the cost is just counting the money, it’s a dead end addition, subtraction, multiplication and division, why... there are so many weird things.

Li Hui looked complicated, and asked Yin Xuan: "Brother Zhengyang, sister Wu Jue... seem to be asking for guidance?"

Yin Xuan nodded.

"But didn't she go to calculate the cost?" Li Hui's face became more complicated, "Why... started the topic."

Before Yin Xuan could open his mouth, Wu Jue explained: "Economic issues are originally a complicated mathematical problem. People's hearts are different, and there are many variables in it."

"If you only count costs, expenses, and profits, then there is no problem in running a small business. After all, the business is small and the impact of variables is small."

"But like this kind of big business, a little variable has a big impact."

Li Hui nodded, her eyes lit up: "Then if you do the math, can you calculate everything in the world?"

Wu Jue nodded, then shook his head again: "Theoretically speaking, this is indeed the case."

"But people have limits after all. It is difficult to take into account all variables, and even the emergence of some variables is unreasonable and illogical."

As she spoke, she paused for a moment: "Don't look at what I'm calculating now, it's just a theoretical value."

"Not very reliable."

"But some references are better than no references."

Li Hui nodded with a vague understanding.

Wu Jue is a strong girl, and she is also a smart girl. In mathematics, her talent is not very good, but she is hardworking.

Naturally, her ability cannot compare with those who specialize in mathematics, but...it is more than enough to deal with some basic economics problems.

Temporary calculations, Wu Jue was a little bit strenuous, writing and drawing, detoured a lot, and after about an hour of calculations, he came to a result.

Wu Jue took a deep breath, ordered the table, and said softly, "I figured it out here, assuming...they only work in the area of ​​Chang'an City."

"It will take about half a year to pay back."

"If we want to expand, it will take two to five years to pay back the cost, only counting the area within the customs."

Yin Xuan raised his hand, pointed at the result obtained on the paper of Wu Jue, and laughed: "Look."

"They need so much time to pay back, so what's the rush?"

"They are still in the stage of spending money to open up the market."

Wu Jue took a deep breath and nodded. She knew that she was a little impatient. She picked up the paper and was about to get up and leave when she sat down again and lowered her voice so that only the people at the same table could hear: "Dalang, should we trip them up?"

Yin Xuan glanced at her, pondered for a while, and nodded: "I will."

"Let them think they're doing the right thing."

Wu Jue understood.

He left in a hurry, pretending to look anxious.

Those who could sit in the Tongfu restaurant were naturally inclined to Yin Xuan, but...there were so many people, and this matter was passed on from person to person after all, and it fell into the ears of Changsun Wuji.

What kind of person is Wu Jue?

Changsun Wuji still has some understanding.

The chief supervisor of Fengchao, but... he is not good at nourishing Qi.
