Chapter 779: Welfare of the Night Phoenix Club 2

The whole staff screamed, but the instructor said so, they can only do it, hey, bear it, bear it until the next semester, you can grab it! !
Even though I thought so, everyone went crazy when I opened the textbook.
Although it's weapon knowledge, what you see when you open the book is the feeling of a history textbook.
What? In 1259, Yan Guo invented the first "gun"-the "fire spear" that used black powder to launch projectiles and a bamboo tube as the barrel. Its basic shape is...
for……
I can't watch it anymore, I hate rote memorization! !
However, Zhou Wei directly opened the multimedia blackboard, connected his laptop to the lecture.
On the multimedia blackboard, photos of the flare gun appeared immediately, as well as various structures, configurations, and production processes.
Since many people saw a gun for the first time, even the oldest gun they saw for the first time. At this moment, many people were staring at the multimedia blackboard.
Ye Yunxi also stared at the blackboard. Although she had learned it before, she really didn't mind reviewing it again.
After the course was over, Zhou Wei called the monitor and went to his office to get some gunpowder.
"Since you learned the structure and principle of the flintlock guns, this week's homework is to make the flintlock guns by yourself. For today's course, you will use the flintlock guns to evaluate the scores."
Make your own musket?
The students were excited again.
Since I can't touch the gun, it seems interesting to make one myself.
The students got enough gunpowder and left the classroom excitedly.
As if thinking of something, Zhou Wei said loudly: "You are not allowed to do it in dormitories, classrooms, and crowded places. You can do it in a place that is not easy to catch fire!"
If Ma De causes a fire again by making a musket, it will be in trouble!
The students patronized with excitement, responded with a lip, and ran away with their things.
Heishuicheng looked at Yeyunxi, "Where are we going?"
"Go back to the club first."
It’s time to post club benefits as soon as the class is in session.
"Okay!"
A few people returned to the club classroom, and the emperor was no longer evil. I guess there was something else.
Ye Yunxi didn't care too much. The gunpowder was carefully put aside. She turned around and said, "I said it last weekend. I will give everyone benefits when I come back this time."
All the people below are looking forward to it.
Especially Bai Shao, who had witnessed the magic of that thing with his own eyes, and naturally looked forward to this so-called welfare more and more.
What would it be that can make a person progress so fast?
And now that he can finally see this thing, he is so excited!
Ye Yunxi was not hypocritical, exchanged the Xijin Yisui and Yizhi Pill from the system, and sent two pills per person.
Anyway, it doesn't take many B-squares. These two tablets total 3000B-squares, and nine people are only 2W7. Now I do a task by myself, and the B-squares are not less than 100,000.
I used to think it was quite expensive to exchange these pills, but now I really feel, haha, eat, eat as much as you can! !
Holding the pill in his hand, Bai Shao looked carefully and carefully.
The small pills are very moisturized in color, with a faint fragrance. Smell carefully, you can smell a faint herbal smell, but if you want to smell what ingredients are in it, hehe, it really smells like death. Not coming out! !
Can these two small pills have such a magical effect?
Shao Bai said that he really wanted to take a grain back to study and study, but...
If he studied, what would he eat! !
