Everyone screamed, but the instructors said so, and they could only do it, hey, bear with it, endure it until the next semester, and you can touch it!!

Although I think so, everyone will go crazy as soon as I open the textbook.

Although it is weapons knowledge, when you open the book, you will feel like a history textbook.

In 1259, Yan invented the first "gun" - "assault gun" that used black powder to launch projectiles and bamboo tubes as barrels. Its basic shape is ......

For......

I can't stand it anymore when I see this, and I hate rote memorization the most!!

Ran Zhou Wei directly opened the multimedia blackboard, connected his laptop, and began to lecture.

Photographs of the assault rifles immediately appeared on the multimedia blackboard, as well as various structures, configurations, and production processes.

Since many people have seen a gun for the first time, even if it is only the oldest gun, it is the first time they have seen it, and many people are staring at the multimedia blackboard with burning eyes at this moment.

Ye Yunxi also stared at the blackboard, although she had studied it before, she really didn't mind reviewing it again.

After the course, Zhou Wei called the class leader and went to his office to get some gunpowder.

"Since you have learned the structure and principles of the assault rifle today, then this week's homework is for you to make the assault rifle by yourself, and today's lesson will be based on the assault rifle you made, and the score will be evaluated."

Make your own muskets?

The students were excited again.

Since you can't touch the gun, it seems like it's fun to make your own.

The students received enough gunpowder and left the classroom excitedly.

Zhou Wei seemed to remember something, and raised his voice: "It's not allowed to do it in dormitories, classrooms and crowded places, you can find a place that is not easy to catch fire!" ”

If Mader causes a fire by making a assault rifle again, it will be in trouble!

The students were excited, and when they answered, they ran away with their things.

Heishui Makoto looked at Yeyunxi: "Where are we going?" ”

"Let's go back to the club first."

It was said that the club benefits would be distributed as soon as the class was held, and it was time to send them.

"Good come!"

A few people returned to the club classroom, the emperor was no longer evil, and it was estimated that something would happen.

Ye Yunxi didn't care, the gunpowder was carefully put aside, she turned around and said, "I said last weekend that I will give everyone benefits when I come back this time." ”

Everyone at the bottom was looking forward to it.

Especially Bai Shao, he had witnessed the magic of that thing with his own eyes, and naturally looked forward to this so-called welfare more and more.

What could it be that can make a person progress so fast?

And now that he can finally see this thing, he is almost excited!

Ye Yunxi was not hypocritical, and exchanged the Muscle Washing and Puzzle Pill from the system, and sent two pills for one person.

Anyway, it doesn't cost much b, these two grains are a total of 3000b, nine people, it's just 27, and now I'm doing a task by myself, and the b-grid is not less than 100,000.

I used to think that it was quite expensive to exchange these pills, but now I really think, hehe, eat it, you can eat as much as you can!!

Holding the pill in his hand, Bai Shao looked at it carefully and carefully.

The small pill, the color is very moist, with a faint aroma, smell carefully, you can smell a faint herbal smell, but if you want to smell what ingredients are in it, hehe, it really can't smell until you die!!

Can just these two small pills have such a miraculous effect?

Bai Shao said that he really wanted to take one back to study and study, but ......

What does he eat if he studies it!!
