Logically speaking, Qin Di got a printing machine and semi-finished legal currency. If he was willing to print counterfeit money, he would agree to bring a lot of wealth, but counterfeit money would disrupt the domestic economic order. How could he do such a thing?

In order to reduce the trouble, he simply burned the semi-finished fiat currency and wrote a letter to Han Jiang and asked him to hand it over to the Yangtze River Bureau.

The letter came to Chongqing for more than a month. When Mr. Ge opened the letter paper, he saw only one sentence on it: "Do you want a money printing machine? Number machine? Cutting machine?"

Mr. Ge was surprised and happy, and slapped the table with excitement: "Where did this letter come from?"

A staff member replied: "This is transferred from the Magic City!"

Boss Ge was overjoyed: "Call back immediately: Such machinery is urgently needed! Ask the capable personnel to take action, be sure to do this!"

Soon, Han Jiang took the call back and came to Qin Di carefully.

Qin Di looked at him and said, "I'm ready for the things, and it's still the same as before. The machinery is hidden in the cabin and pressed under the corn. You can go to Hancheng with the boat yourself and don't leak news!"

"Yes, thank you Mr. Qin!"

Soon, the Shaanxi-Gansu-Ningxia Border Region, the Shanxi-Chahar-Hebei Border Region, and the Hubei-Henan-Anhui Border Region each obtained a set of money printing machinery, and the printed "anti-coin" was even more exquisite! These border areas originally had money printing machines, but the machinery used was too simple, with defects from ink to Taolin paper, so the printed paper money was uneven and had to be destroyed and started over.

After several contacts, Qin Di's identity, in the eyes of some "semi-informed" people, is equivalent to an "enlightened capitalist" and a "object to be fought for."

But in the eyes of a very small number of insiders, Qin Di is like a "red capitalist".

However, it is the same for Qin Di. Capitalists are capitalists, and they are ultimately different from the proletariat. He doesn't care much about this. Because the times are changing, he has a lifespan of hundreds of years, so why bother with just thirty years?

Let’s talk about Unit 731. After receiving the letter from Mr. Qing, the Da Chi Party attached great importance to this matter and immediately sent someone to investigate.

Later, the Northeast Anti-Japanese Allied Forces made great sacrifices and failed to annihilate all 731 parts, because the Japanese army was in a strong position in the Northeast, and there were not only one Japanese biochemical troops, but 63 detachments distributed in various battlefields. Harbin, Changchun, Peking, Jinan, Qingdao, Jinling, and even Guangzhou had branches. It was too difficult to completely eradicate them!

For example, the 1855 troops in Peking, the "Jingsheng Biological Survey Institute", the 1644 "Tamo troops" in Jinling, the 2630 troops in Changchun, the 8604 troops in Guangzhou, and even Singapore have similar detachments.

However, because Deng Huo studied the explosion and leakage of viruses and chemicals, the Japanese suffered, so the indirect impact was that the number of times they used chemical weapons on the Chinese battlefield also converged.

Qin Di stayed in the Demon City and continued to carve his Sumeru magic circle. After a month, he covered the surface of the gourd bottle with 10% of the area.

The Sumeru magic array is also divided into levels, including large magic arrays, medium magic arrays, small magic arrays and mini magic arrays, as well as spiritual arrays, treasure arrays, immortal arrays, and divine arrays.

With Qin Di's skills, he can only carve small spiritual arrays for the time being, each of which is like a soybean.

Each additional magic array on the gourd bottle can increase a considerable internal space.

He could carve a magic array in an hour. As of late April, he had completed a total of 480 magic arrays. The bottom of the gourd bottle expanded to the size of two football fields, and the narrowest part of the neck of the gourd bottle was more than ten meters. But he carved several sealed magic arrays on his neck, so even if he turned the gourd upside down, the things inside would not fall out.

Qin Di used the gourd bottle as a magic weapon, but for the time being, the magic weapon is too low and too big, so it is not convenient to carry it with you.

However, there is nothing to worry about. After repeated sacrifices and refining in the future and turning into high-level spiritual weapons, they can become larger and smaller.

In April 25, 1939, Qin Zhan returned from studying in the United States.

She came back by plane, first flew to Manila, then to Hanoi, Vietnam, and then from Hanoi to Kunming. After arriving in Kunming, she did not dare to fly again because the domestic airspace was unsafe, and the Japanese Air Force might launch an attack on civil aviation passenger planes at any time.

As early as August 24, 2018, a civil aviation passenger plane of AVIC flew from Hong Kong to Chongqing was shot down by Japanese military aircraft. The crew and passengers died 14 people, and only 3 survived.

Qin Di and Yan Xue received a telegram in advance and went to Kunming to greet him in person.

At this time, Qin Zhan was already 27 years old, wearing black-framed glasses and a black striped suit, dressed simply and intellectually.

Qin Di asked with a smile: "Have you obtained your doctorate?"

Qin Zhan took out a gold-plated certificate, which was full of English and seals.

Qin Di took a look and saw that it said "Doctor of Mathematics at Princeton University."

He felt very pleased and praised: "You are really capable and have obtained your degree. There are very few people in China who can achieve this step!"

Qin Zhan smiled and said, "Brother, don't talk nonsense! There are many mathematicians in China. Hu Mingfu took a doctorate from the Department of Mathematics in Harvard in 1917, and there were more than a dozen similar people, each of whom was better than me."

"Ahem, how can those stinky men compare with my sister!"

Yan Xue walked up to him and asked with concern: "How many days have you been flying? Are you exhausted?"

Qin Zhan replied: "I had been working back and forth for seven days. If I had known what, I would have been better off taking a steamship!"

Qin Di asked: "What are the arrangements after returning to China?"

Qin Zhan said: "My father helped me find an errand in Chongqing, saying it was beneficial to the War of Resistance."

"It has to do with cracking the password?"

"Well, this is what I learned."

The group went to Qin Yue's house to stay for two days.

At this time, Wang Shu was still creating new operas, while Qin Yue worked part-time in college. Their son Wang Shao was already 4 years old.

During the dinner, Qin Yue said to Qin Di: "Brother, I will give you 10,000 tons of food you have stocked up and give it to various universities. Those children are so pitiful that they can't even eat enough and have to study hard. I feel very uncomfortable when I see it."

Qin Di smiled slightly: "You are also the master of the Qin family, so of course you have the right to dispatch the grain store. How many students are there in Southwest Associated University?"

Qin Yue replied: "Southwest Associated University is a university composed of Peking University, Tsinghua University and Nankai University. The total number of students in each grade is no more than 2,000."

Qin Di was a little surprised: "There is only such a small number of people? Can I use 10,000 tons of grain?"

If it were later generations, there would be tens of thousands of people in a university.

Qin Yue said: "Brother, Kunming is not only Southwest Associated University, but also more than ten colleges and universities including the private Sino-French University, National Arts College, National Tongji University, etc. The total number of students, teachers and family members is tens of thousands! You don't know that since the War of Resistance Against Japan, Kunming, Chongqing and Guilin have become the centers of cultural education."

"Oh, so that's it."

Then Qin Yue said again: "From the year when I moved here, starting from December 1937, the Yunnan-Burma Highway began to be built. There were no less than tens of thousands of people working in Yunnan to build the road every day. I saw that those workers were not full, and they had to take shifts and nights to repair, so they sold them 40,000 tons of grain at 50% of the market price."

Qin Zhan was shocked: "Sister, do you have to lose money if you do business like this?"

Qin Yue looked ashamed and said, "I am not a business man, I want to complete the Yunnan-Burma Highway soon."

Qin Di smiled and said, "It doesn't matter. I'm storing food here not to make money, but to help the people of Kunming overcome difficulties."
