In this era, when it comes to biotechnology, Japan is the world's first.

All of this was experimented with by the Japanese devils on China's human life.

Germany is the second, on the other hand, the United States, which is the most technologically and economically developed, cannot even rank in the top ten, and even Switzerland cannot compare.

Fang Buwei remembered that the original Jinling poisoned wine case used potassium cyanide given by the Americans, but in the end, looking at the effect, even the arsenic that has been inherited in China for nearly a thousand years can't be compared.

But whether it is Japan, Germany and Switzerland, there is no way to do it, so we have to find another way.

Therefore, the poisons and drugs that Fang Bu used for the past two years were all made up by himself.

This is also the reason why he is the self-proclaimed No. 1 master of drug use in the Republic of China.

Don't underestimate the wisdom of your ancestors.

For thousands of years, with the change of dynasties, the palace infighting, poison, this thing has been studied to the extreme by the ancestors.

Don't think that for thousands of years, China has only had arsenic as a poison.

The reason why this thing is so famous is entirely because it can be accessed by the general public, and it is used too frequently, so it has become famous.

Don't think that the broken intestine grass in martial arts, the crane top red, and the poison are made up.

These things really exist.

Li Shizhen's compendium of materia medica can be found.

After arriving in Nanyang, Fang Buwei deliberately studied these poisons.

Hu Wenhu started selling medicine, and most of the masters in his hands were masters who could recognize the nature of medicine and defend poison, so he asked them for help, and he developed several poisons that sealed his throat with blood.

In addition to the above three, there are ricin, hen beads, broken intestine grass, and even snake venom.

Among them, snake venom is naturally the most effective, but it is also snake venom that is the most difficult to preserve.

Fang Buwei thought about it and sent another telegram to Hu Wenhu.

It was to the effect that Mr. Hu was asked to tell Sin Chew and Hong Kong that as long as it was something that could poison people, they would bring a big bag to Mr. Yu Qiaqing's freighter to Shanghai on the freighter where Mr. Yu Qiaqing imported rice.

Yu Erjun, Chen Jiageng, and Hu Wenhu all knew that Fang Buwei was in Shanghai at this time, and they also knew why he came to Shanghai.

Fang Buwei is not afraid that after poisoning people at that time, these people will suspect him, if you ask, I will simply admit it.

From Sin Chew to Shanghai, it may take a week, and from Hong Kong it is even faster, up to five days.

Fang Buwei estimated, at most, ten days, the poison he asked for could be sent to Shanghai.

Ten days later, it is not certain whether Ma Chunfeng can formulate a perfect poisoning plan.

The time was totally in time.

……

Ma Chunfeng can't describe his mood at this time.

He first received a secret telegram from "his own people", and was wondering if this "own person" was hiding in the headquarters of the Japanese army invading China, otherwise how could he know so clearly the specific itinerary of the two commanders-in-chief of the Japanese army that invaded China?

There is no way to explain this with reason.

Ma Chunfeng hesitated for most of the day, considering whether to activate the "thorn" immediately to verify the authenticity of the news.

In the end, he just did it.

For a Yamada Otozo, if the thorns are exposed, how to think about how not cost-effective.

Let's notify the military commander at Nanjing Station first, and see if we can get some information through the Japanese Embassy in Nanjing.

As a result, as soon as the secret telegram from Nanjing was sent, there was movement on the Shanghai side.

Soon after dawn, about eight o'clock, the telecommunications office of the Military Command Headquarters received Yuan Shu's request contact code: There is urgent information, 100,000 urgent!

Yuan Shu rarely used the words 100,000 urgency to mark the intelligence level, and when Ma Chunfeng saw the message, his heart jumped first.

It is not that I have not encountered the large-scale search and arrest of Japanese spies in Shanghai against the military command and the underground party before. Every time he asked for silence, Yuan Shu implemented it very well.

Defying the latent order and strongly demanding contact, this is the first time.

Ma Chunfeng had a strong premonition in his heart: Yuan Shu asked for contact this time, and the information transmitted would not be related to the secret telegram sent by "his own people", right?

Ma Chunfeng immediately instructed the Director of Telecommunications, Qi Zhenjiang, to inform Yuan Shu that he could be contacted, but he had to choose the most secure communication channel.

Yuan Shu immediately called back: contact through the radio immediately.

As the second-in-command of the Japanese foreign affairs spy system in Shanghai, the actual person in charge of the Iwai Mansion, and the spiritual leader of the Xingya Founding Alliance, Yuan Shu actually has a fairly high degree of autonomy.

He has his own independent investigation and operation organization, and is also qualified to coordinate with various Japanese spy agencies in Shanghai and the Shanghai Japanese Military Police Command, and he also has an independent radio station exclusive to the Xingya Alliance for the Founding of the People's Republic of China, which he leads.

As long as there is a reasonable excuse to send secret messages to the Japanese embassies in various cities in China, this method of communication is the safest and fastest communication channel at present.

When he saw the first secret message sent by Yuan Shu, Ma Chunfeng not only stared out of his eyes, but his heart almost jumped out of shock.

Shunroku Hata officially stepped down from his post as commander-in-chief of the Chinese Dispatch Army, returned to Japan, and took over as Minister of War and Commander-in-Chief of the Dispatch Army, and was succeeded by Yamada Otozo, the former commander of the Third Army of the Kwantung Army......

Ma Chunfeng suppressed his beating heart, and took the secret telegram sent by "his own people", comparing them word by word.

The secret telegram sent by "his own people" not only contained all the information mentioned by Yuan Shu, but even calculated the time of Yamada Otozo's departure from Mukden, the route, and even the approximate time to Shanghai and Nanjing.

That's it, he also suggested that the military commander could formulate an assassination plan based on this itinerary......

Does this "own person" know that there is an inside line of the military command inside the Nanjing Embassy?

Theoretically impossible, but Ma Chunfeng had an extremely strong premonition: this own person may really know this information.

Think about it a few days ago, "my own people" found Liu Geqing like a ghost and broke Wang Tianmu's hiding place......

Simply killed the dog?

Ma Chunfeng felt as if he had eaten a yellow lotus, and his mouth was bitter.

What is the origin of this own person, feeling like a fairy?

Regardless of the speculation that followed, just comparing the two telegrams, it felt as if he was also listening to the meeting.

No, Yuan Shu also attended the meeting, but he didn't know as much as him.

Ma Chunfeng's heart jumped, and he picked up two telegrams again.

After comparing it again, Ma Chunfeng found that something was wrong.

There is information written in an affirmative or definite tone, which is basically similar to what Yuan Shu sent.

The rest of the part is calculated by his own people......

Ma Chunfeng's breathing gradually became heavier.

He found that he had already touched a little bit of "his own people".
