Seeing Tan Si throw the pack of chicken bones into the trash can, Cao Bin returns with him.

"Let's go, Chief Tang." Tan Si said very barely. He knew that if Tang Jin didn't ask about the matter clearly today, he would not let him leave easily.

"Go to a place with me and have a drink." No matter what, Tan Si is not his enemy.

Tan Si also knew that Tang Jin did not dare and would not do anything to him.

...

A black shadow flashed, and a man appeared next to the trash can. He looked dirty and looked like a beggar, but his eyes were very bright.

He reached out and searched in the trash can, and he flipped over a bulging leather bag. He hid it in his arms and quickly disappeared into the darkness.

Fukaisen Road, Lu Xiyan’s home.

After dinner, Meng Fanxing reviewed her homework in the room. For the sake of Meng Hao's engagement, she had several classes, borrowed the lecture notes recorded by her classmates, and tutored for herself in the evening.

Lu Xiyan is still working on his doctoral thesis. This is not because the teacher sent many medical journals to him. He has to study hard and get the useful ones out.

In addition, he did not give up on the idea of ​​establishing a factory for "medical sterile cotton".

He also asked Yan Lei to conduct an investigation to see the market demand for "sterile medicinal cotton" in Shanghai and the manufacturers to see if he could directly acquire a factory, which saved a lot of time.

Since we cannot let these 5,000 tons of cotton raw materials fall into the hands of the Japanese, we have to find a way out for them. We can't pile them in the warehouse and get moldy.

The land for building a factory is not difficult.

The key is equipment and technical talents. If Chinese people don’t work, they will look for foreigners.

I wondered whether to look for Hu Yunzhi tomorrow. If you have difficulties, find an organization. A person’s power is too small, so the power of the organization will be much stronger.

There were footsteps outside the door, and the force was only Yan Lei.

The footsteps of everyone in the family were in his mind, and he could hear who was close to the study.

The footsteps were a little anxious, something was wrong.

Everyone in the family must knock on the door whenever they enter Lu Xiyan's study. As long as Lu Xiyan is not here, only Yan Lei and Meng Fanxing have the keys in the study, and others will never be allowed to step into the study.

Even Lao Mengtou and Meng Hao are not qualified.

Yan Lei was holding a cowhide bag in his hand, which looked very old. He had been using it for at least many years and had oil stains. It seemed that his owner did not properly keep it.

"The fourth brother just sent someone to send this bag over, saying that he was brought from Fein's house." Yan Lei said with his bag in his hand.

“Check no?”

"I didn't open the bag, but I pinched it with my hands, there should be no danger." Yan Lei said.

"Give it to me." Lu Xiyan nodded and signaled Yan Lei to hand him the bag.

"Sir, I'll do it." Yan Lei said.

"You come, is there any difference between me?" Lu Xiyan smiled, "Can your fourth brother still harm me?"

"This is impossible."

The bag was not locked, but it was fastened and opened easily. There were a stack of yellowed drawings inside, with about forty or fifty pieces.

A full bag.

Lu Xiyan studied medicine, but when he was a teenager, he also came into contact with drawings, maps, etc., and he could understand them. Of course, the military-purpose ones are not good.

As long as you have received a certain degree of education and are familiar with guns, you can tell at a glance.

The drawing is an exploded diagram of the gun parts.

"Fenn is amazing. He can actually design firearms!" Lu Xiyan was so surprised that he couldn't understand a lot of the data and structures on it, it didn't prevent him from knowing what this was.

He is good at repairing guns and changing guns, but he may not necessarily build guns. Fein not only knows how to repair guns and change guns, but also a person who can design guns and build guns.

No wonder Andre took him so seriously.

These gun design drawings are probably what Andre wants the most. No, there is also Fein, as long as he is there, he will have as many drawings as many as possible.

But we are all going to immigrate to the United States together. Are these things still useful to them?

However, those who are interested in these things are probably not ordinary people. Andrei has hooked up with the Japanese. Do the Japanese want to get the design drawings of Fein's guns?

The Japanese army's light weapons design is indeed not very good, at most, it is considered a second-rate level, but it is still much better than China.

At least they can build anything. China cannot build artillery with a caliber of more than 100 mm, and Western powers are also prohibited from exporting.

The materials are not good, the design is not good, and there is no talent yet.

Although these drawings are incomplete, their value cannot be estimated for a country's weapons industry and cannot be copied and manufactured. It is also meaningful to learn from them.

"Yan Lei, go and take the camera, take pictures of these drawings for me to save." Lu Xiyan ordered.

"Yes, sir."

Yan Lei has been following Lu Xiyan for a long time. With the influence of his eyes and eyes, his knowledge has naturally improved much more than in the past. Such an important drawing is obviously not measured by money.

"I'll make an appointment with Chen Sancai tomorrow. He is a major in mechanics and electrical engineering. He should be able to understand the drawings. Please pick one and take it over and ask him to identify it to determine whether these drawings are real." Lu Xiyan ordered.

"Okay." Yan Lei took the camera, and the two of them moved the homework from the coffee table to the carpet, and took pictures one by one.

I worked hard for more than an hour before I took all the drawings.

"Where is Tan Si? He sent someone to send the drawings. Where are his own people?"

"I was called away by Tang Jin." Yan Lei said.

"Why did you tell me now?" Lu Xiyan was a little angry.

"The fourth brother was blocked by Tang Jin in an alley not far from Fein's house. He was so quick to make a fool of himself and took advantage of the opportunity to throw away the garbage." Yan Lei explained.

"Tang Jin knows Tan Si's identity and should not do anything to him. However, I don't know how many words Tang Jin will mess with him." Lu Xiyan said, "No matter who he is, the cooperation will break down. Anyway, Tang Jin didn't tell us the truth this time."

"Brother An Zi, Yan Lei, what are you two muttering in the study?"

"Quick, put away the drawings." Lu Xiyan was startled and quickly put the drawings on the floor into his leather bag with Yan Lei.

"Meimei, aren't you reviewing your homework in the room?"

"I just went downstairs and saw Yan Lei talking in your study. It's been a long time, and you are still talking. What are you talking?" Meng Fanxing asked curiously.

"I, I told Yan Lei that the establishment of a sterile medicinal cotton factory." Lu Xiyan smiled and explained quickly, "Didn't I ask him to help me investigate the market situation of this sterile medicinal cotton? He reported to me just now."

"Brother Anzi, are you really planning to do this?" Meng Fanxing said in surprise.

"I haven't decided yet, so I want to first understand the market conditions, demand, etc. If I can do it, it can consume the cotton raw materials in our hands and make money. Why not do it?" Lu Xiyan said.

"Yes, Mrs. Fanxing, I visited several hospitals this day. They all said that the price of sterile medicinal cotton imported from abroad is relatively high, but the quality is high and the quality is good. Domestic ones have a lot of poor quality and relatively cheap quality. In the whole of Shanghai, the demand for medicinal defat cotton is about 3-5 tons per month. Hongwei Company acquires seed cotton purchased in India. The seed cotton needs to be deseeded. One hundred kilograms of cotton can get about 37 or 8 kilograms of cotton. After defat and process, we finally get medical defat cotton. Fortunately, we did this matter solidly, otherwise, I don't know how to answer. (Are there any professionals? Please check it out. This information is really hard to find. If the data is incorrect, please point it out)

"So, if all the 5,000 tons of cotton in our hands are used to produce medicinal defatted cotton, at most less than one-third."

"It's almost like that."

"If we build such a factory, what is the most suitable output?"

"This requires professional calculations. My estimate is 300 to 500 tons per year. If it is really not possible, about 200 tons." Lu Xiyan said, "The batch of raw materials we have in our hands can be supplied to us for production for at least five years. When cotton is kept at constant temperature and humidity, the quality of the five-year storage will not change much."

"Where is the funds?"

"This..." Lu Xiyan smiled embarrassedly, "We are just considering feasibility. As for the money issue, we haven't thought about it yet."

"You two have been discussing this all night?" Meng Fanxing said.

"Yes, otherwise, what do you think we two big men can do without sleeping at night?" Lu Xiyan smiled.

"Sir, it's getting late, it's time for you and your wife to rest." Yan Lei quickly ran away. If he continued, the little thing in his stomach would definitely be exposed.

"Well, time passes so quickly. It's almost twelve o'clock. It's time to go to bed. I have to go to work tomorrow." Lu Xiyan yawned and said, "Meimei, we should go to bed too."

...

Windsor Hotel, Tang Jin's secret private room.

"Team leader, this Tan Si is very terrifying, not a single word of truth." Cao Bin said angrily.

"What can you do to him? Whatever you say, he is also on the same line as us." Tang Jin was also a little irritated and smoked seven or eight cigarettes in one night.

He rarely smokes so much at night.

Cao Bin was silent. If Boss Dai had not ordered this "arms" case in person, they would not have reached out to care about this matter.

If they don’t even expose themselves, it’s completely unworthy of the gains.

"When will Mr. Lu arrive?"

"It should be soon after the curfew," Cao Bin said.

"You go down and see if you have arrived?" Tang Jin ordered.

Just as Cao Bin was about to get up, he heard the knock on the door "three longs and two shorts". This was the secret code of his own knocking on the door. Cao Bin went over to open the door.

There were three people standing at the door. One of Cao Bin's subordinates knocking on the door, and Ding Songqiao and a middle-aged man wearing glasses and a leather jacket beside him.

His face is thin, his beard is mixed, and he looks a little decadent.

"Mr. Lu, long time no see, please come in. We, Chief Tang, have been waiting for a long time." Cao Bin recognized the identity of the person wearing a black leather jacket at a glance.
