During this period, there were not many biological and chemical weapons dropped by the devils, but they could cause significant damage to the Eighth Route Army every time.

The damage is continuous, and many fighters, even if they survive the gas bomb, will cause permanent damage after recovery.

This damage is not only physical, but also mental, and at the same time brings low morale.

Units that have been hit by poison gas bombs usually have a slower recovery period than other units.

Yao Guangyuan was silent and silent for a long time.

Seeing that he was silent, Xu San took the initiative to speak: "It's not realistic to ask us to equip the troops with gas masks, but simple kettles and towels are still fine, and one or two more corresponding exercises should be able to have a good effect." This drill doesn't need to be done on the sly, we can do it openly. ”

"Why is that?" Lin Dong asked curiously.

"In order to show the devil." Yao Guangyuan smiled and explained to this junior, "We can plant intelligence officers in the hinterland of devils, and they can also arrange spies in our troops." ”

"Our purpose is to prevent the devils from using poison gas bombs, biological and chemical weapons like poison gas bombs are very expensive to manufacture, maybe dozens or even hundreds of times that of ordinary artillery shells, if they are dropped on guarded troops, won't it be a loss?" Xu Sanyou explained it from another aspect.

"The views of the comrades in the group are really unique, no wonder the staff are praising your strategic analysis."

"Hehe, I used to be a small trader, so I'm more sensitive to money." Xu Sanyi smiled, avoided the important and trivialized, and wrote the strategic analysis well, because he knew history and knew the trend of the war in the later period. If he is really asked to be a staff officer and write a report, it is estimated that he will not be able to hold back a fart for half a day.

"You're too modest!"

"Another point, that unit not only makes poison gas bombs, but also creates viruses and drops viruses, such as the plague, they can arrange a few spies to drop a few mice with viruses in the base area, presumably this is also very easy, right? Moreover, the plague virus studied by 731 may be extremely contagious, I think Comrade Hengshan should know the harm of plague, right? ”

Of course, Yao Guangyuan knew the harm of the plague, and when he thought that the devil actually used the plague to harm people, he couldn't help but punch the table: "These beasts! ”

"Hehe, saying that beasts is really lifting them up!"

The evil things that 731 did were simply terrible, but Xu San had no way to make these evil things public to the world now.

Today, he is here to uncover the corner of this hijab first, and the rest is to slowly draw it.

"Do you have any good advice from the group leaders?"

"Exterminate the rats! As long as the rats are eradicated, the source of transmission is eliminated. I don't have much other suggestions, I think there should be people in the organization in epidemic prevention, they are professional in this kind of thing, and others interfere, then the layman leads the insider, and may do bad things with good intentions. ”

After listening to Xu San, Yao Guangyuan also realized the importance of this matter: "How much do you know about that unit?" ”

"I don't know much, just what they do, and the names of a few officers. The poison gas bomb and the plague just mentioned are just speculations, speculations made based on what happened to Chen Changhai. ”

Yao Guangyuan looked at Xu San in front of him and thought to himself, what a powerful young man, he can pull out so many things with just a little clue, fortunately he is not a real puppet army. However, in order to ensure the correctness of the intelligence source, he still asked: "Regarding that unit, what about your intelligence source?" ”

"A friend of Dongying, I can only say so much."

"Dongying also has friends?" At this time, Lin Dong interjected again.

"In the devil army, there are also anti-war factions in the country, after all, now that the war is like this, the little devils can't bear it, and their living standards in some areas are not as good as the people in our base areas." Xu San popularized the domestic situation of the little devil for the young ear comrade.

Before Yao Guangyuan set off, the second section also analyzed Xu San's identity and intelligence sources, including that there may be an anti-war faction in the devil army on Xu San's intelligence line.

It is precisely because of this that the review of it will be simplified, and as long as there is no treasonous tendency, it can be developed first.

Yao Guang is far from getting to the bottom of it, and the fewer people like this important informant know, the better.

If Xu San told him that he was exposed and arrested one day, he would confess this important informant if he couldn't stand the torture.

"Comrade Er, have you written down all the things reported by the group leaders just now?"

"Write it down!"

Regarding 731, Yao Guangyuan chatted with Xu San for a while, and Xu San also said everything he could say, after all, Xu San's own understanding was limited, and there were some things that were out of the times, and he couldn't say anything.

"Comrade Xu San, have you ever wanted to go over for further study?" Yao Guangyuan suddenly asked.

"Further education?"

"Yes, but ......"

"I know, when I get rid of the little devils, I think it's a little early for me to go."

"You can understand best, to be honest, I am still quite conflicted in my heart, on the one hand, I hope you can go to Kang University for further study, and on the other hand, ....."

Xu San smiled, "Didn't I make a choice for you?" Don't be embarrassed. As he spoke, he patted Yao Zhiyuan on the shoulder.

"Just understand!" Yao Guangyuan also smiled, and then changed the topic: "Isn't it lonely to be an intelligence officer?" ”

"At the beginning, it was very powerful for a while, and at that time it felt like I was the only one left in the whole world, and then I met Lao Qian, and then I made a joke with him." After speaking, Xu San smiled bitterly, it seemed to be a little self-deprecating, he was quite lonely at that time, although he knew that he wanted to resist Japan and save the country, but he still felt confused and directionless.

"What kind of joke, can you tell me?" Yao Zhiyuan seems to be very interested in this.

"Hehe, don't talk about it, they're all comrades, it's embarrassing to say it."

"Then let's not talk about that."

"So what?" Xu San asked.

"Are you interested in leading the intelligence work in Ping'an County?"

"Me? All right? Xu San was a little surprised in his heart, he never dreamed that this audit would be so simple, and he was promoted after the audit.

"I say you can do it, you can do it! Didn't you lead the rescue operation of more than 300 people? Almost no shots were fired to save 300 villagers intact. ”

"It's a fluke, and it's a lot of luck. Don't say that luck is also part of strength, you can't fool me with that. ”

The words were blocked, Yao Guangyuan was not angry, just pouted, "This is an order!" ”

"Then there is no way! I obey orders. ”

Yao Guangyuan tidied up his clothes and stood solemnly in front of Xu San: "Comrade Xu San, now I officially appoint you as the person in charge of the intelligence station of Ping'an County, Jinxi, codenamed Quntou." ”
