"I'll only teach the knowledge of my class once, so you'd better memorize it all over again." Nangong Yin looked at the backs of all the people and said.

"The rules of my class depend on my mood, I'm in a good mood, you can do whatever you want, but if I'm in a bad mood, I'm so embarrassed that you hit the muzzle." Nangong Yin took the laser pointer and clicked on the computer projection.

"You are not under my control now, but if you annoy me while I teach, I have a thousand ways to punish you."

"Okay, I'll put the words here, what to do is still your business, now start the class." I clicked on the video.

"Today is about the classification of firearms." Nangong Yin said with a laser pointer.

"A pistol is a short-barreled weapon with a one-handed grip for aimed fire or instinctive fire, usually carried by commanders and special forces, for self-defense and surprise attacks on the enemy at a close range of 50 meters." Nangong Yin put Liandie down on the podium, "What I brought is a pistol." ”

"The basic characteristics of modern pistols are: change the safety, load the cartridge, change the magazine, compact structure, and simple automatic mode."

"Modern military pistols mainly include self-defense pistols and submachine guns. The firing range of the self-defense pistol is generally 50 meters, the magazine capacity is 8~15 rounds, the firing method is a single shot, and the weight is about 1 kg. Submachine pistol, also known as combat pistol, fully automatic, generally equipped with a split stock, magazine capacity of 10~20 rounds, can be used as a submachine gun in peacetime, effective range up to 100~150 meters......"

Nangong Yin is not only talking about theoretical knowledge, she also has the experience of fighting to tell Zhan Chenyi and them.

Zhan Chenyi listened to the girl's class, and the more he listened, the more he felt that the girl's knowledge reserve was so rich!

"In addition to that, assembling guns is key." Nangong Yin directly dismantled the butterfly and assembled it in an instant.

The whole process didn't take more than a minute or even thirty seconds.

Nangong Yin took the butterfly and looked at the people below: "I'm blind and the assembly speed is probably faster than your normal assembly." ”

Lin Fei raised his hand and looked at Nangong Yin: "Teacher, it's better to compete." ”

Nangong Yin raised her eyebrows and looked at Lin Fei, can't this person not dismantle the stage?

Nangong Yin looked at Lin Fei, and Lin Fei's information sounded in his mind, the special forces who could enter the top three in the imperial capital army with blind eyes.

Nangong Yin sighed, looked at Lin Fei and said, "Compared to what?" ”

Although Nangong Yin was not outstanding among the commanders of the North Hall School, Nangong Yin was still very confident in Lin Fei.

"Blind assembly." Lin Fei looked at Nangong Yin defiantly.

"You can 01 prepare, I'll finish the lecture first." Nangong Yin continued to teach Zhan Chenyi and them, "The last hour is in Bican!" ”

Lin Fei sat down, and 01 heard Nangong Yin's words and went out directly to prepare things.

Nangong Yin didn't care either, and continued to take class.

In the last hour, when Nangong Yin had almost finished the class, 01 came in with something to step on.

01 Directly pour the contents of the phone in the first row.

Nangong Yin watched as the parts of various equipment were scattered on the table.

Nangong Yin twitched the corner of her mouth, it's not that 01 doesn't need so much! There are at least a dozen of them to be assembled!

01 Put the things on the two tables very evenly.

Lin Fei had already come down and stood in front of Nangong Yin.

Now Lin Fei had a thought of defeating Nangong Yin, and he really couldn't accept that he would be defeated by Nangong Yin's hands.

Nangong Yin looked at Lin Fei, who was a little serious, and smiled indifferently.

There are many people who want to defeat me, but I'm still the Commander of Butterfly Love.
