After hearing the laughter, Huang He quickly turned his head to look at the door for the first time. On weekdays, everyone in the laboratory is busy with their own business, and everyone hardly visits the door.

Coupled with Wang Dexing's guard, the door of the Yellow River has not been locked several times throughout the year, but he forgot that there was a woman who did not follow the routine in the laboratory this month.

In turbulent times, there will always be some people who take the unusual path.

Although most of the women in the Republic of China period are still hidden in the boudoir, there are always a small number of outstanding women who have discovered the changes of the times and awakened their consciousness.

The woman in front of her is one of them, and she enters the new school with the support of her parents. He graduated from the Preparatory Department of the National BJ University in 1931 and the Department of Physics from the Faculty of Science of the National Tsing Hua University in 1935.

Later, under the recommendation of Mr. Yan, she went to Zhengbaiqi University for further study, and her outstanding talent made her immediately appreciated.

Her supervisor was the Nobel Prize in Chemistry in 1935, and because of her outstanding learning ability, she also entered the Institute of Nuclear Chemistry of the Gallic Chicken Academy.

After two years of hard work, she successfully completed her doctoral dissertation and received her Ph.D. in the same year.

If there is no war, Chang Jiang may continue to work in a foreign country and continue to move forward on the road of physics until one day waiting for the call of the motherland.

But the war disrupted all the rhythm, and as Santokuko's troops pressed forward step by step, the originally comfortable research environment disappeared.

Even though her mentor tried her best to dissuade her, Chang Jiang made a choice that shocked many people.

Instead of fleeing to the south on her bicycle, as most natives do, she made her way to Lyon alone, where there were ships to return home.

Fueled by the awakening of the Yonghu system, Chang Jiang returned to his motherland without danger, and came to Jin Province with the help of a group of underground workers.

Originally, she planned to go to the rear after a short rest in the base area, but when she found out that there was a laboratory here, she immediately became interested.

After a few days of investigation, she decided to stay here. After all, in terms of her profession, there is no room for her to play in the entire motherland at present.

Instead of staying in the rear like a vase, it is better to study the data here with many scientists.

Whether it is Shan Wenbao or Wu Sixue, she is very attractive to her, she didn't expect that there are so many talented people in the small logistics department.

What's more, there is even a nominal senior here. And after the exchange, Chang Jiang was immediately attracted by the project in the hands of Huang He.

After all, it was from 401, and no one who studied physics could refuse.

She came to Huang He today to discuss the matter of chemical protection clothing, after all, there has been preliminary progress in theoretical research.

But I didn't expect that Huang He, who was quite serious in the past, was secretly playing dress-up games in the room alone at this time. She immediately laughed when she saw this scene, then said hello and walked into the room.

Looking at the Adrian helmet on the head of the Yellow River, Chang Jiang stood on tiptoe and raised his hand to touch the top of the steel helmet, and said with some pity:

"Hey, why is the cockscomb gone? Missing that part is simply missing a soul. But you don't look like a soldier at all, but more like a firefighter over there. ”

Huang He just got off the bike, and the embarrassment on his face had not faded. Facing Chang Jiang's ridicule, he didn't know how to answer for a while.

But the other party obviously saw this, so he continued: "I don't know what happened to my mentor and friends, life in enemy-occupied areas must not be easy, war is really disgusting. ”

"It's really a shame that a big country has only lasted for more than 40 days."

This sentence made Huang He also feel a little emotional, but fortunately he knew that the day of the end of the war was getting closer and closer. It is precisely because of this that he has to seize all the time to make a national-level killer. Looking at the Yellow River, who was a little distracted, Chang Jiang stretched out his hand and shook it in front of the other party's eyes, and then said:

"Don't forget about the chemical protective suit, you and I have both read the information. Radiation protection materials are very important, and this matter depends on you. ”

"Although I don't mind living on analgesics and drugs for the rest of my life, I can't die before I get out of school."

After finishing talking about business, the two chatted casually, and then Chang Jiang prepared to leave here. Before leaving, she seemed to remember something, turned back to the Yellow River and said:

"By the way, Minister Zhang said that he will come to you in a while, let me say hello to you in advance, don't forget it."

Because in the entire laboratory, except for the newcomer Chang Jiang, the rest of the people are not very willing to move the nest. So Zhang Wanhe quickly got acquainted with the other party, and sometimes asked her to help inform the Yellow River if there was something.

After all, Wang Dexing really has no face, and many times he is a person who is trained.

Huang He nodded, he naturally knew the reason why Zhang Wanhe came to the laboratory, in order to check this batch of equipment.

What's more, many fighters have never touched gas masks before, so be sure to familiarize them with this new equipment in advance.

As the saying goes, how to fight in wartime and how to practice in peacetime. Only then will the right instinctive response be made when a real crisis comes.

If you don't use your equipment correctly, you probably won't be able to get the most out of it.

Just like those recruits who died worthless in World War I, although they have gas masks that cannot be used reasonably, they can only struggle in pain in the face of enemy gas.

For the fighters, the first problem they faced was unaccustomed to the vision. The system supplied a gas mask with two separate eyepieces.

Unlike later masks with a one-piece eyepiece, the split eyepiece greatly affects the user's field of vision.

And because of the canister, some fighters are likely to look down and not see their feet after wearing them. After the start of the war, it is quite possible not to see how much ammunition is left on the bullet belt.

Therefore, before the start of the big war, it is necessary to go through a certain amount of training to get the fighters used to the presence of new equipment. And practice a lot to form muscle memory.

It also takes time to get used to the feeling of wearing a mask. When a mask is worn, the way a person breathes is affected. Learn to control and change your breathing.

Also try to wear a mask during your workout routine to see what kind of activity can cause fogging or make it difficult to breathe.

After all, after the devils have fired the gas bombs, they will not wait for the gas to dissipate before attacking, and then the meaning of biological weapons will be lost. Once the battle begins, the fighters may move at any time to fight.

Soon Zhang Wanhe came to the outside of the laboratory with three comrades, and Huang He and Wang Dexing were already waiting at the entrance of the compound with a set of support equipment.

Looking at the various equipment on the stone table, Zhang Wanhe couldn't help but smile. His own deputy minister will never let him down, and every time he can get the equipment that the front-line troops need in time.

During the previous waiting period, Huang He deliberately handed over a sapper shovel to Wang Dexing and told him to take it to the military industrial area to cut the blade.

At this time, the sapper shovel is no longer the harmless appearance of humans and animals as before, and the tip and blade of the shovel are already cold and drenched after polishing, just picking it up makes people stand upside down.

After seeing everyone in place, Wang Dexing stepped forward with a sapper shovel. After getting Huang He's approval, he took the shovel and walked to the sandbag that Zhang Wan had just brought to them.

The guard first moved his limbs to warm up, and then slashed at the sandbag in front of him with his sapper shovel.

The blow broke a large hole in the sandbag, and the yellow sand inside leaked outward.

Wang Dexing looked at his masterpiece with satisfaction, and then changed it to a thorn. The entire shovel surface sank into the sandbag like a hot knife cutting butter, and even part of the wooden handle was inserted into it because of the force.

Finally, it was the process of verifying the excavation and the tree, and the sapper shovel perfectly conquered everyone present. Even Zhang Wanhe, who has not been on the battlefield for many years, has itchy hands and can't help but want to take a shovel and cut a few devils to vent his anger.

Next is the main event, the three comrades who came to the laboratory this time have their own characteristics, they are long faces, round faces and square faces.

This is to test whether people with different face shapes will have different effects when wearing gas masks.

Judging by their appearance, the comrades are not very old, and even their faces are a little immature. But their expressions were resolute, their eyes were firm, they were all high-spirited, and they were full of energy, as if they were not afraid of a mountain of swords and a sea of fire in front of them.

Next, Huang He explained to them the detailed steps of wearing gas masks.

Before wearing it officially, the fighters need to check the equipment. For example, whether the appearance is damaged or deformed, whether the elasticity of the headband is normal, and whether the filter box and filter cotton are within the shelf life and clean and pollution-free.

You need to wear it as soon as possible, and you don't have time to check it at that time.

Once everything is in order, you can start wearing it.

In the first step, hold your breath and then cover your mouth and nose with the mask, fix it on your face, and pull the headband frame up to your head and neck.

In the second step, pull the headband underneath towards the back of the neck and buckle it. Exhale more and then inhale after bringing it in.

The third step is to carefully check the connection and the tightness of the exhalation and suction valves to ensure that no air is circulating between the face and the mask.

The three comrades were not bad at hands-on skills, and their ability to accept new equipment was also very strong, and it took about five minutes to get used to operating in gas masks.

The experiment here is over for the time being, and after returning to the military industrial area, there will be training closer to actual combat waiting for them.

The remaining steel helmets and portable radio stations and other things were all taken away by Zhang Wanhe, and the space in this compound is not large enough, and many equipment are not suitable for quality inspection here in the laboratory.

According to the estimates of the Yellow River, the production capacity of five military factories could equip at least three main regiments before the start of the war. In the second stage of the war, the needs of the troops will be almost satisfied.

There will be a while, before 12 o'clock. The number of portable radio stations is different, almost one out of 500 sets.
