At the end of April 1942, a small incident occurred in the suburbs of Harbin Special City, Binjiang Province, Manchukuo.

It is said that the Japanese army's epidemic prevention and water supply department often flew water, but the fire was quickly controlled and there was no major sacrifice. Under the harsh cover of the Japanese and puppet military government, this matter hardly spread among the civilians, and it completely stopped.

So much so that in the subsequent official history, there was no trace of this matter at all.

Naturally, no one paid attention to what department is the epidemic prevention and water supply department and what work is the factory of the epidemic prevention and water supply department.

But behind all this being concealed, the Japanese Lieutenant General Shiro Ishii was furious.

First, the data from the special research room of the pharmaceutical factory was burned down. Fortunately, for the sake of data safety, the data room would regularly send the backup to the Kwantung Army General Information Archives Office for collection.

Next is the research results of the Ministry of Epidemic Prevention and Water Supply on bacterial warfare over the years. The data room filled with bacterial research materials was also burned down.

Although most of the data are backed up, the data on that special small shelf is the research results in recent months, and there is no time to submit the backup!

This is a considerable loss.

The most serious thing is that after investigation, the arson was obviously invaded by foreign enemies, which means that the epidemic prevention and water supply department and the pharmaceutical factory have been completely exposed to the enemy's nose. They have already touched it and burned the data room, which is very likely to have stolen a large part of the data.

Shiro Ishii was angry about this. He arranged the defense work of the Ministry of Epidemic Prevention and Water Supply and the Pharmaceutical Factory Laboratory by himself. It can be said that it is not leaking. How could the enemy infiltrate?

check.

I will investigate thoroughly and I cannot let go of any clues.

As a result, even the shadow of the enemy was not discovered.

The Japanese sir who was specifically responsible for the investigation of this arson incident was a rare talent with unique talent in case investigation. After the final investigation and careful investigation, he finally determined four conclusions:

First, the culprit of this arson incident must be internal personnel.

Otherwise, there is no explanation for his ability to enter the special laboratory of the pharmaceutical factory and the epidemic prevention and water supply department silently.

Second, through this incident, the final corpses were thoroughly investigated and found that the pharmaceutical factory and the epidemic prevention and water supply department had two bodies lowered upwards, and perhaps more, but it was impossible to accurately judge because they were burned by the fire.

But what is certain is that this time the enemy should have committed the crime by a gang, with more than one person.

Third, Director Kitahara Matsushita was stabbed to death from the front. Judging from the strength and perspective of the dagger piercing into the heart, it should have been thrown out by the enemy. It would take time for the dagger to cross a distance in the air. If Kitahara Matsushita did not know this person, he could react a little while he was alert, but the dagger was inserted into his heart without bias. This shows that he was caught off guard at the time.

Then the murderer must have known Kitahara Panasonic, and may still be very familiar with him.

According to the fire and the judgment of witnesses at that time, the fire in the special laboratory of the pharmaceutical factory and the fire in the water supply department factory basically occurred at the same time.

Therefore, it is unlikely that a person commits a crime, unless he knows the clone technique, or he uses other methods.

So who will this insider be?

The Japanese Grandmaster who was in charge of this matter was lost again.

The 606 employee dormitory was burned and there were six bodies inside, which means that all the members were back. The guard remembered that an intern returned at around 11 o'clock. As for who it was, the guard couldn't remember.

The special laboratory of the pharmaceutical factory was burned down, and there were two burnt corpses inside, with unrecognizable faces and no identity could be distinguished.

The old director, who is nearly 70 years old, is very distressed by this. One of them is his student, and it is said that he is the nephew of Naokawa, the Minister of Military Advisor of New Beijing.

"When did this Koimiro...he came?" The pole vaguely felt that he had caught some key points.

The old director Hiroichi Ono roared: "You idiot, what are you doing in the security work in the laboratory? He actually let the enemy infiltrate. This is my most proud and talented student, and it is ruined in your hands. What do you ask about these things? Could it be that you still suspect that I, the student, is the murderer?"

The master was scolded and said, although the old director was a researcher, his military rank was much higher than his. Not only did he be scolded, he could only be taught respectfully.

Shiro Ishii also believes that it is no point in chasing the real murderer at this time. Next, we must make up for the loss and speed up the security work of the pharmaceutical factory and the epidemic prevention and water supply department.

In addition, when the news reached Shiro Ishii's ears, he could order the Harbin Special City to be blocked. He guessed that the culprit had not yet walked away after stealing the information from the information room. If he wanted to leave, he would definitely be exposed.

On the other hand, it is the relationship network of Koumirou disguised as Han Feng.

Masaki Miyashita was very regretful and blamed himself, thinking that he had harmed Han Feng. If he hadn't suggested taking Han Feng to work in a pharmaceutical factory, he wouldn't have killed Han Feng.

Sakurai's family was shocked and sighed, and Ayako secretly cried in her room all night.

Sakurai Ichiki and Sakurai Kazuka ended up regretting that their good son-in-law disappeared like this. I wonder if his uncle would blame his family.

Fukuki Naokawa, who was far away in Xinjing, also received the news. While heartbroken, he sent a letter to Koimirou's father to express his guilt.

Because of Han Feng's accidental death, the incidents that happened one by one.

Things seemed to have passed like this, and Koimirou, the man, disappeared completely into the eyes and ears of everyone.

All these incidents were quickly concealed, because all this personal sacrifice was not worth mentioning compared to the hidden work of the Kwantung Army's epidemic prevention and water supply department.

In the 606 dormitory, the deaths of six students who came to work in the epidemic prevention and water supply department will also be concealed, and their relatives in China will not even receive news.

From this point of view, it is impossible for Kawatani to have the pension for his unsustainable family to be paid.

As time goes by, I think that Koemijiro, the Japanese, will soon be forgotten by the people I know around me. Perhaps in the end, the only person who still remembers Han Feng is the only girl Ayako, who looks like a piece of paper.
