When Jiang Lai returned home, he naturally didn't know the follow-up. Of course, he was not in a hurry. If there was any news, the police station would call.

However, today the appearance of this person who is suspected to be a skilled craftsman reminded him of something very suddenly.

Although he can still read the knowledge of engineering and even physics in memory, he knows... these things cannot be done without the support of materials.

In today's era, what China lacks is not only some principled knowledge, but also the support technology that can realize principles.

It is actually very difficult to build these things. In the later generations, many scientists in the Republic have really crossed thousands of miles step by step, overcome countless difficulties, and sacrificed many people...

Only then did China have a sword in its hand and not fear the West.

Resisting Japan and saving the country, promoting technological progress, probably... is the voice of all time travelers coming to this era.

Jiang Lai smiled and pulled out paper and pen from the bookshelf. This time... what he was going to write is not medical knowledge anymore.

...

The next day.

"Liu Xinming, one of the main chief engineers of Dahua Instrument Factory." With that pocket watch, Zhou Wei found the identity of the victim, but he did not expect that he was the chief engineer of Dahua Instrument Factory!

I heard that he is an old technician.

"Yes, police officer, we, Gong Liu, cherish this watch very much. We said every day that we wanted to give it to our daughter as a birthday gift. All the parts were polished by him and it took a lot of effort!" A worker explained, "But Liu..."

...

Jiang Lai frowned as he heard the sound on the phone. Sure enough, he was an old technician.

"I have a daughter named Liu Yajun. She should have returned to China in recent days. The finely crafted pocket watch I picked up at the scene was the birthday gift that Liu Xinming wanted to give to his daughter. All the parts were polished by him."

On the other end of the phone, Zhou Wei talked about his investigation.

"I have also asked about Liu Xinming's interpersonal relationships. It is said that he is a good man, and he has no enemies or dissatisfied with him. I thought what happened last night was like an accident. I also found a spy to check on the person who committed the crime, but there is no news yet."

"Thank you for your hard work." Jiang Lai responded, "I just called to ask about Liu Xinming's situation this morning. When the person woke up, the situation was basically the same. He said he didn't know the person who beat him."

"Okay, I'll continue to catch it."

"If you can notify his family as soon as possible, please notify me."

"OK."

After hanging up the phone, Jiang Lai sighed slightly that when he was about to reunite with his family, Liu Xinming was really unlucky when he encountered such an accident.

"Liu Xinming?" Lin Wan thought about the name, "I know him."

Today is Sunday. She didn't go to work, so she came to visit Jiang's house because Jiang came out...there are too many risk factors.

Jiang Lai was surprised, "So famous?"

"Yes, one of the representatives of the older generation of craftsmen." Lin Wan nodded, "I heard that I can visually estimate the size of anything, and the error is very small."

Jiang Lai was surprised. This was really...it was a little more powerful. "After this operation, he may leave sequelae..."

“Say?”

"Difficult speech, weak hands..."

Lin Wan was stunned, "This..."

Jiang Lai also sighed and shook his head, "Now, it's not very accurate, it depends on his own condition."

Lin Wan was silent, and things in the world were always unpredictable.

"By the way, I remember what I want to tell you today." Lin Wan quickly changed the subject, "I finally found out about Sun Chengjie's incident."

"Yoyou Kasai?" Jiang Lai frowned, "Hideo Kasai? Who has a very good relationship with Kotaro Iwakawa?"

"Yes." Lin Wan nodded, "I continued to investigate later and found out that he, Kotaro Iwakawa and Yusuke Nanbu, came to Shanghai together, and each opened different companies and operated different businesses."

"You mean... Iwakawa Kotaro's incident was leaked?"

"No, it's just... I suspect that these three people are closely related to the Japanese spies." Lin Wan said his own inference.

Jiang Lai nodded, "Actually, the Japanese have coveted our land for a long time, because they have less land, fewer resources, and more natural disasters than ours... Many Japanese merchants have cooperated with the Japanese military headquarters and contributed free funds to inquire about information and draw maps for the Japanese military headquarters."

Lin Wan was surprised, "Really?"

"Yeah." Jiang Lai nodded and said, "Maybe, a thousand years ago, this covetousness had already planted the seeds in their hearts. The Opium War, the Sino-Japanese War of 1894-1895... Time and again, the weakness of China was exposed in front of these empires, and their fangs were naturally revealed."

"But one of the important reasons why we didn't become their colonies is because the culture that has been passed down for a long time has made our backbone hard enough."

"So, I'm not surprised that you found Yoshi Kasai."

"So that's the case." Lin Wan laughed and expressed her understanding, "However, there is one thing you may not have imagined."

"What?"

"That widow Liu was able to send her child to Yosuke Kasai because she had a sex relationship with Hideo Kasai."

Jiang Lai was indeed surprised. After all, he only thought that Liu's son would be the intermediary correspondent because he worked at Kasai Yosuke, and he did not expect...

"The world is difficult, and it is even more difficult for a widow to take care of a child." Lin Wan sighed, "As for now, even if we know these things, there is no evidence. In court... we can't do anything to the other party."

Jiang Lai sighed, "It's true that we can't do anything to the other party, but we are determined to pursue it. Lawyer Zhou should find a way as soon as possible."

"He just needs to put all the blame on Sun Chengjie..."

Yes, as long as they are determined that they have nothing to do with Sun Chengjie, there is no way to deal with each other.

"So, I need one chance." Lin Wan stared at Jiang Lai seriously, "A chance to get close to Hideo Kasai."

"No." Jiang Lai directly refused.

"Why?"

"The timing is sensitive, Iwakawa Kotaro has just died not long ago. Even with the same technique, it will still cause doubts." Jiang Lai explained. He knew that Lin Wan wanted to vent his anger, and knew that killing a Japanese businessman who served the Japanese Military Department was not difficult for Lin Wan.

But now, the relationship between the two countries is tense, and it looks calm on the surface, but in secret it is actually turbulent.

"You mean, unless Hideo Kasai died unexpectedly in a conflict with the Japanese in public... isn't our fault?"

"Yeah." Jiang Lai nodded, "but it's very difficult, the timing, occasion, and motivation."

Yes, in the land of China, the Japanese are actually quite united.
