778 The Welfare of the Night Phoenix Society 2

All the staff screamed in agony, but the instructors said so, and they could only do as they did. Hey, bear with it, bear with it until next semester, and you can grab it! !

Even though I thought so, everyone would go crazy when they opened the textbook.

Although it is weapon knowledge, when I open the book, I feel like a history textbook.

What in 1259, the State of Yan invented the first "gun" - "sudden gun" that uses black powder to fire projectiles and a bamboo tube as the barrel. Its basic shape is...

for……

After seeing this, I can't stand it anymore, I hate rote memorization the most! !

However, Zhou Wei directly opened the multimedia blackboard, connected his laptop, and started lecturing.

Immediately on the multimedia blackboard, photos of the blast gun appeared, along with various structures, configurations, and production processes.

Since many people saw guns for the first time, even the oldest guns were the first time they saw them. At this moment, many people were staring at the multimedia blackboard.

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

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

"Since you have learned the structure and principle of the flash gun today, then this week's homework is to make the flash gun by yourself. In today's class, the score will be assessed according to the flash gun you made."

Make your own guns?

The students were excited again.

Since you can't touch a gun, it seems interesting to make one yourself.

The students got enough gunpowder and left the classroom excitedly.

Zhou Wei seemed to remember something, and raised his voice: "Don't do it in dormitories, classrooms, and crowded places. Find a place where it's not easy to catch fire!"

It would be troublesome if Mudd caused a fire again because of being a flaming gun!

The students were excited to patronize, and with a snort, they took their things and ran away.

Heishuicheng looked at Yeyunxi: "Where are we going?"

"Go back to the club first."

It was agreed that club benefits would be distributed as soon as the class started, and it was time to distribute them.

"Okay!"

Several people returned to the classroom of the club, the emperor was no longer evil, and it was estimated that there was something else.

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

Everyone below is looking forward to it.

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

What would be something that could make a person progress so fast?

And now that he was finally able to see this thing, he was about to die of excitement!

Ye Yunxi was not pretentious, and exchanged the Tendon Washing Yisui and Yizhi Dan from the system, and sent two pills per person.

Anyway, it doesn't cost much B. The two tablets are 3000B in total. Nine people, it's only 2W7. Now that I do a task by myself, the B is not less than 100,000.

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

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

The small pill has a very moist color and a faint aroma. If you smell it carefully, you can smell a faint herbal smell. However, if you want to smell what ingredients are in it, hehe, it really smells like death. don't come out! !

Can these two small pills have such a miraculous effect?

Bai Shao said that he really wanted to take one back for research, but...

If he studied it, what did he eat! !
