Without transitional analysis, Iwai Eiichi and Harada Kuroyoshi can guess who the code names represent in this message.

Schizonepeta is the driver, the secretary is He Jianying, and later Boss Fu, and the doctor is Ma Sanhu. Both of these are the offline of Thorns in Shanghai.

The agreed plan in the telegram is exactly the same as the trajectory of today's action trajectory of Wu Sibao, Ma Sanhu, He Jianying and others.

For example, Ma Sanhu and He Jianying called to test, then called Wu Sibao to notify him, and Wu Sibao arrived in Kunshan in the name of transporting morphine, and then fled to Suzhou...

Iwai Hide had no doubt at all. Someone framed it.

Others can be stolen, but Wu Sibao is not a puppet, so why do he do whatever others say?

Could it be that when he saw Hikoshiro Suga, he ran away, because someone else framed him?

Harada Kumayoshi was also sighing secretly.

Akagi Kenji is worthy of being an anti-espionage expert and has no mistake at all.

Because Teacher Lin was shot dead, the Military Affairs Bureau Headquarters sent Thorns a message reminding him that the message that the money had arrived was not accepted, so Chongqing doubted whether there was something wrong with Thorns.

In desperation, Chongqing temporarily activated the dark boy lurking in Shanghai, which is the driver of Ma Sanhu: "Shinope". Shinope took the risk of contacting He Jianying and Ma Sanhu, and met Wu Sibao again, and then what happened later...

At this level, Wu Sibao's charges could no longer escape, but Iwai Hideichi was not in a hurry.

He wanted to convince Wu Sibao that he was convinced, even if it was to let other traitors understand that He Iwai Hideichi was not killing the donkey, and he had to find some ironclad evidence.

There are many other things that are suspected of evidence. Akagi Kenno is constantly identifying it. Iwai Hideichi believes that there will definitely be greater discoveries...

In the office next door, Iwai Hideichi was carefully organizing a lot of fragments with seven or eight subordinates.

Everyone wore hats, masks, gloves... just a white coat, which was no different from the researchers at July 31.

The easiest group of subordinates were holding a few blank pieces of manuscript paper, shining in the sun or blowing toner, identifying the marks on it, hoping that all the words on it could be revealed.

Akagi was beside him, staring at another group of subordinates, carefully cleaning up the paper ash in the brazier.

The brazier was brought from the house rented by He Jianying. Most of the manuscripts inside were burned and half were not burned. You can imagine how urgent He Jianying left.

There are words on the burned paper ashes, but the unburned part is blank. One of Akagi's relatives knew it was written in secret ink, which must be confidential information.

In order to ensure that the information above can be seen as clearly as possible, Akagi Kenji had to arrange special personnel records.

After recording the contents of the top layer of paper ash, the spy will gently sweep off the layer of paper ash with a brush, then remove the unburned upper half, and start recording the lower layer...

Akagi asked his subordinates to wear masks because they were afraid that the airflow of breath would be too large and the paper ash would blow away.

In fact, there is no need to be so careful at Akagi Guanzhi.

Since Fang Buwei made arrangements, he would definitely give the Japanese the most complete information as much as possible.

Except for the two above, which were specially used to attract the attention of the Japanese spies who were searching, the rest of the burned parts were all without words...

After cleaning up to the third piece, seeing that there were fewer and fewer handwriting on the paper ash, the speed masters of this group couldn't help but get much faster.

"Your Excellency, you've tried it out!" Another group of spies shouted happily.

Akagi Kenzu walked over quickly.

There is a basin of water on the table, with half a basin of water in the basin, and there are all kinds of things next to it.

Iodine, alum, alcohol, hot water, and even ice cubes are available...

A piece of original blank manuscript paper floated on the water, and blue handwriting was displayed.

Fearing that the handwriting would disappear soon, Akagi Kenji arranged three recorders, one of whom was responsible for copying some of them.

"How did you try it?" Akagi Kenzu asked excitedly.

You can see that the part in the brazier can reveal the handwriting by burning it with fire.

But Akagi Kissie couldn't really use fire to burn it.

First, he was afraid that there was too much information on it, so the copyist would burn the paper before he could record it. Second, he had to ensure that he could not only know the specific content of the information, but also completely preserve the original.

So Akagi Kissino could only let his subordinates try it out the same way.

"Add boiling water!" replied the subordinate.

Akagi Kissou frowned. Are these men stupid?

Even though you know that you will show your words when you encounter high temperatures, there is no other way except to heat water?

"Why don't you try to roast it on fire?" Akagi Kenji said, "You're not really asking you to burn it?"

A leader turned red, he quickly took the alcohol lamp to light it, and then took another blank manuscript paper, and baked it close to the flames.

The handwriting is indeed shown on the paper.

"It's cobalt salt!" Akagi said firmly.

Cobalt salt is chlorine and cobalt. It was invented by the Germans at the end of the World War and was used to make color-changing cement in the early stage. I don’t know which genius suddenly had an idea and developed a secret writing ink.

This thing has a characteristic: when it is hot, the characters will appear, and when it is cold, the characters will disappear. Therefore, compared with other secret writing inks, the biggest advantage is that secret writing can be read repeatedly and preserved for a long time.

However, few people know that cobalt salt has this characteristic. Akagi personally can't figure it out. Where did the spies from the Military Control Commission learn it?

As long as you try the cracking method, the next speed will be much faster.

In less than an hour, this group cracked all the secretly written manuscripts, including the pieces of paper picked up from the brazier.

His subordinates sorted out the recorded documents and handed them over to Akagi Kishin. He just took a look and his heart hopped.

Wu Sibao deserves to die...

He closed the folder and quickly ran to the next door.

"Your Excellency, please check it out!" Akagi handed the folder to Iwai Hideichi.

Iwai Eik opened it and saw that the top line of the first page read He Jianying, meaning that this information was found from He Jianying's room.

On the left is the spy copied and sorted out, with very neat handwriting, and the back is the original, each of which is only half a piece, which is obviously burned by fire.

What impressed Iwai Hideichi was particularly the handwriting on the original was that the words on it were crooked and very ugly.

He has seen this font more than once, and he can recognize it as Wu Sibao's handwriting at a glance.

It should be that Wu Sibao passed the information to He Jianying through Ma Sanhu, and then He Jianying passed it to Boss Hu, sent it to Dachang Town Primary School, and passed it to Chongqing by radio.
