Chapter 2542
"Yes, yes, we should listen to His Highness Tang Yu and all move back five meters."
Seeing the solemn looks on Tang Yu and Lu Xiangning's faces, all the students realized that this was not a joke, and they all stepped back five meters.
All the instructors present also became nervous. Although they didn't know what Tang Yu was going to develop, they felt uneasy in their hearts, as if something big was about to happen.
Moreover, everyone present had a hunch that Tang Yu's fourth invention would definitely shock the audience!
"Xiang Ning, go get me an umbrella."
Tang Yu raised his head and glanced at the scorching sunshine. When developing gunpowder before, it was the sunlight that almost caused irreversible consequences. With the lessons learned from the past, Tang Yu seemed to be more careful this time.
Although the amount of gunpowder is not that large this time, the power is not a joke. If it is not operated properly, it is likely to explode.
Without any hesitation, Lu Xiangning opened her umbrella to block the strong sunlight.
Tang Yu carefully poured out the gunpowder, and the smell of gunpowder in the air became stronger.
Seeing this scene, all the students looked like curious babies, their eyes focused on Tang Yu and Lu Xiangning.
Remember URL
"With such a strong smell of gunpowder, is His Highness Tang Yu planning to make fireworks?"
"It's really possible. After all, except for fireworks that require gunpowder, other things don't need gunpowder at all. I want to see what's different about the fireworks made by His Highness Tang Yu."
"Fireworks? I don't think it's that simple. Maybe His Highness Tang Yu is inventing something even more amazing."
Everyone was talking a lot, and no one knew what kind of medicine was in Tang Yu's wine gourd.
You know, gunpowder already existed in ancient times, but its main purpose was to make fireworks.
However, they didn't know that what Tang Yu wanted to make was not fireworks, but the most lethal gunpowder among the four methods!
The gunpowder used in fireworks is not the same as the gunpowder used in warfare.
The former has a very low ignition point and its power and lethality are not too strong.
But the latter is a mixture of sulfur, saltpeter, charcoal, etc., and is also called smokeless gunpowder.
The gunpowder made by Tang Yu is not only terrifyingly powerful, but also ignites quickly, and can be stored for a long time without deteriorating.
"Pretend to be a ghost!"
Qin Feng glanced at Tang Yu with disdain, his brows filled with disdain and sarcasm, but he didn't take Tang Yu seriously.
In his opinion, gunpowder is gunpowder. Even if Tang Yu makes flowers, they are just ordinary gunpowder. They are not interested in making fireworks at all.
Soon, a landmine made of ancient gunpowder appeared in Tang Yu's hands.
Tang Yu carefully placed the landmine on the ground, sweat appeared on his forehead, and he even stopped breathing.
Any large movements or touches may detonate the mines, and Tang Yu did not dare to be careless.
"Xiang Ning, please retreat first."
After Tang Yu placed the mine, he kept retreating with the lead in hand.
After retreating to a place five meters away from the mine, Tang Yu breathed a sigh of relief.
All the students looked at me suspiciously, and Tang Yu smiled and said, "The next step may cause you discomfort. It's best to cover your ears and open your mouth first."
As soon as these words came out, Qin Feng stood up first and sneered.
"You're still covering your ears? Aren't they just a bunch of broken fireworks? There's nothing to make a fuss about, but I won't!"
Hearing this, an intriguing smile appeared at the corner of Tang Yu's mouth, and he suddenly pulled the lead in his hand...
