(I will update this article for all the readers who gave me tips)

After meeting with the team leader Comrade "Xinghuo" in a private room in the teahouse, Zhang Jianglin hurriedly left after getting the team leader's entire plan.

He was going to go to the office of "Shimazaki Yokado" and convey to Shimazaki Osaka his decision to sell 9,000 sulfa drugs to Colonel Tanaka.

As a disciple of Zhang Jianglin, Shimazaki Osaka only owns 9% of the shares of "Shimazaki Yokado".

On the surface, he is the president of Shimazaki Yokado, but he cannot make his own decisions.

Furthermore, his current status and title as a wealthy businessman were all given to him by his master Zhang Jianglin.

As for the decision on whether to sell sulfa drugs and to whom to sell them, he had to follow the decision of his master Zhang Jianglin.

When Zhang Jianglin returned to the office of Shimazaki Yokado, he explained to Shimazaki Osaka that he could sell all 9,000 sulfa drugs to Colonel Tanaka.

Shimazaki Osaka also knew what he should do next.

The first two times Colonel Tanaka invited him to a banquet, Shimazaki Osaka politely declined on the grounds of poor health.

This time, since his master Zhang Jianglin has decided to sell all the sulfa drugs to him, Shimazaki Ochirō has the confidence to accept the invitation.

Using the office phone, I called the hotel where Colonel Tanaka was staying.

Colonel Tanaka was also very happy when he heard that Commander Shimazaki was finally willing to accept his invitation.

They immediately agreed to have dinner at a well-known izakaya in Shanghai.

When Shimazaki Osaka went to meet Colonel Tanaka this time, he did not dare to bring his master Zhang Jianglin with him.

He also knew that these Japanese officers who killed people like crazy on the front line could kill Chinese people at will if they were slightly dissatisfied or just drunk.

At the dinner, Shimazaki Osaka pretended to fully support the Empire's war and was willing to make less money for it.

This immediately aroused Colonel Tanaka's great favor, and while drinking, he became brothers with Shimazaki Osaka.

In fact, Shimazaki Oro had no good feelings about this war.

His elder brother, Kazuo Shimazaki, was forced to give up his dream of becoming a big businessman because he was forced to be conscripted, and could only reluctantly serve as a small Japanese officer.

However, even though he hated this war in his heart, he still did not dare to show the slightest bit of war-weariness when facing Colonel Tanaka.

After the dinner, Shimazaki Osaka signed a sulfamethoxazole purchase and sale agreement with Colonel Tanaka.

This time he sold 9,000 sulfa drugs to Colonel Tanaka, at a price that was 30% cheaper than what Inspector Johnson had paid for them.

Even though they offered this friendly price, Shimazaki Yokado still made seven times the profit from this sulfa drug business.

After sobering up the next day, Colonel Tanaka withdrew a Japanese yen promissory note from the bank and paid for the purchase of sulfamethoxazole.

On that day, the sulfanilamide stored in the Shimazaki Yokado warehouse was taken over by a Japanese army squad under Colonel Tanaka.

As the quartermaster of the Sakata Division on the front line, Colonel Tanaka had a squadron of Japanese soldiers at his disposal to transport and protect the various logistical supplies purchased.

Shen Yutang had already placed a real-time locator in this batch of sulfa drugs containers, which was exchanged for 1,000 merit points.

This needle-sized locator could not be detected unless the Japanese army abandoned the box of sulfamethoxazole containing the locator.

Using this locator, Shen Yutang can always keep track of the location information of this batch of sulfamethoxazole.

Therefore, they chose the right time and place to ambush Colonel Tanaka's Japanese logistics squadron.

A Japanese squadron had at least 150 to 20,000 people.
