In the following training, somehow, Mai Sui was suddenly promoted from a student to an instructor.

She alone was 1V199, making Tang Jiangwan, Lin Yanxi and other students suffer a fate worse than death!

This has completely solidified her title of "Female Devil of the Southeast Military Region".

Even the instructors felt a little sorry for what they saw.

But they didn't dare to say any empty words, because Qi Chuanqing had already made it clear that this group of female soldiers would be trained by Mai Sui, and the others should fully cooperate!

Qi Chuanqing had also tailored a training plan specifically for Mai Sui based on her situation.

But after watching Mai Sui's training, he found that he had nothing to teach him.

The weak links of Wheat Ear are actually the simplest common sense issues.

But Mai Sui had almost mastered that knowledge when he was in the military region.

As for the rest, Qi Chuanqing really couldn't teach Mai Sui anything.

On the contrary, there are many aspects of wheat ears that are worth learning for Qi Chuanqing.

In addition to Mai Sui's advanced tactical thinking, there are also her magical inventions.

Qi Chuanqing didn’t think there was anything special about the small bomb that Mai Sui had made to blow up the armory.

Because the bomb was not very powerful, any ordinary bomb expert could make it. The focus that time was on the clever use of physical mechanics.

But the signal gun made by Mai Sui this time forced Qi Chuanqing to take it seriously!

Because compared to ordinary signal guns, this thing's range is much stronger!

The function of a signal gun is to pass on information. The longer the range, the more people can see it, and the better the effect will naturally be!

If it can be mass-produced, it can be foreseen that it will definitely play a huge role on the battlefield in the future!

Moreover, signal guns have both military and civilian uses.

For example, water rescue, desert rescue and so on.

Thinking of this, Qi Chuanqing sent Zhou Cheng to lead a team overnight to return the scrapped "signal gun" to the Southeast Military Region.

He also instructed Zhou Cheng to hand it over to Chief of Staff Huang Zongwei personally.

Huang Zongwei certainly understood the profound meaning behind this gun, so he had it sent to the nearby military research institute overnight.

After Mai Sui learned about this, he generously drew him a simple design diagram of the signal gun.

Qi Chuanqing was a little curious: "You can draw a design? I thought you just did it by chance? Have you ever made something like this before?"

"Of course not, it's my first time making this kind of crap!

Mai Sui used to play with high-end weapons.

“As for drawing maps, didn’t the teacher teach us how to draw maps when we were in the military district before?

Drawing a map is drawing, and drawing a design is also drawing, isn’t it? Is there a difference? "

"No?"

"Is there?"

"...Okay! You're awesome. If you say there's no such thing, then there's no such thing!"

“There wasn’t one.”

However, what Mai Sui didn't know was that the set of design drawings she had previously given to Shen Xingchen had actually caused big problems.

Shen Xingchen was arrested by the military district security department!

Not only him, but also Mai Laosan and Mai Hongcai.

The reason is that after some hard research, Shen Xingchen finally made the portable sewing machine that Mai Sui wanted.

It's just that its power is a bit too strong. It's a waste of money to use it to sew or hem clothes, and it may accidentally damage the clothes.

But as a weapon, it's perfect!

The effective range of a general pistol is only 50 meters, but this one can reach 100 meters.

Of course, its power is definitely not as strong as a pistol.

After all, it is just a sewing machine, which contains a sewing needle and a cotton thread attached to the back.

But if you can't get a pistol, you can use it as a gun.

If your shooting skills are more accurate, it will be no problem to kill someone from a hundred meters away.

Mai Sui is good at making weapons, but this was his first time trying to modify them, so he was unable to control the lethality well.

If Mai Sui had not gone out for special training and had stayed in the military area for the past two months, given her personality, she would definitely have sneaked back home often.

In this way, she could adjust the design at any time during the sample making process, and then work with Shen Xingchen to make the portable sewing machine she really wanted.

But Mai Sui happened to be out for special training!

In order not to disappoint his wife, Shen Xingchen put in a lot of effort and finally got it done.

As a result... instead of receiving praise from his wife, he ended up putting himself in an iron cage.

Originally, this matter would not attract the attention of the military district security department.

Mai Laosan and Mai Hongcai showed it off and even performed shooting shows in the staff compound.

Ordinary family members and children don’t understand these things and just think they are strange, but the soldiers who have returned from training do understand them.

Report them immediately!

What’s even more terrible is that the security department also found the original design that Mai Sui had drawn from his home.

It clearly looks like a gun!

Shen Xingchen made some adjustments to the appearance, and the finished product no longer looks like a gun.

But it was this adjustment that increased Shen Xingchen's suspicion.

According to the Security Department, "If you don't feel guilty, why are you adjusting? I think you are doing this on purpose, trying to cover up your tracks!"

The most important thing is that this thing is too powerful!

It's irrefutable evidence!

Shen Xingchen had no way of explaining himself, so he could only swallow his anger and admit defeat!

But despite repeated questioning by the Security Department, Shen Xingchen still did not give out the wheat ears. Instead, he lied that he designed and made them by himself.

In order to make the people in the Security Department believe it, Shen Xingchen even skillfully re-drew the design draft in front of them.

He had studied the draft of wheat ears countless times, and it had long been deeply memorized in his mind. He could even draw it with his eyes closed.

But the people in the Security Department are not pushovers either. They believe that Shen Xingchen definitely has accomplices!

Because the handwriting is different!

Although Shen Xingchen deliberately imitated Mai Sui's notes, a person's drawing habits cannot be imitated 100%.

The Security Department has professional handwriting identification experts who found the flaw after a careful comparison.

Shen Xingchen is only 20 years old this year. No matter how smart he is, he is still too young.

This was the first time I encountered such a thing, and under such tremendous pressure, it was inevitable that I acted without thinking.

After he was caught, he didn't worry about whether he could escape. His first reaction was to think of Mai Sui, fearing that Mai Sui would be implicated.

Therefore, Shen Xingchen's mind was full of thoughts about how he could take all the blame by himself.

At this moment, he was even glad that he had not yet officially obtained the marriage certificate with Mai Sui. In this way, Mai Sui might not be implicated.

When facing the interrogation of the Security Department, Mai Laosan and Mai Hongcai were surprisingly very tough and did not betray Mai Sui.

But they didn't say that it was Shen Xingchen who did it, they just said that they knew nothing.

"Bullshit! You took it out yourself, don't you know?"

When the people from the Security Department heard Mai Hongcai's excuses, they slammed the table.

Mai Hongcai was so scared that tears came out, but he still pretended to be strong:

"My sister is Mai Sui, who just won the third-class merit! If you dare to hit me, I will definitely tell my sister!"
