Although its lethality cannot be compared with those modern grenades, in ancient times, it was at least a highly explosive weapon as described by Rong Chengxuan, which could kill quite a lot of people.

After a long moment, when the ground had completely calmed down, someone asked Yun Wanwan in a trembling voice, "Princess, is this an earthquake? With these things, can we artificially cause an earthquake?"

After this opening line, someone followed up on this line of thought, "So if this thing can cause earthquakes, then we don't have to fight anymore? We can just dump all this stuff on their territory, and with a few bangs, it'll cause an earthquake. And then once the earthquake passes, some of them will die, some will be injured, and we can easily take their city."

…

Yun Wanwan's mind was abuzz with their wild ideas. As they'd said, the grenade not only caused widespread destructive power but also caused small-scale ground tremors, a bit like a low-frequency earthquake, though the ancients still referred to earthquakes as ground motions.

In their eyes, earthquakes are extremely terrifying because you never know when an earthquake will strike, and every time an earthquake occurs, many people are killed or injured.

Since the new weapon that Yun Wanwan brought out can cause earthquakes, in their eyes, this is the most powerful weapon.

Yun Wanwan listened to their increasingly outrageous remarks with a faint smile. These people were, after all, ancient people, reacting to something that would only appear in who knows how many decades.

To avoid misleading the students, Yun Wanwan loudly explained, "This isn't an earthquake. It's just a small-scale ground tremor. Unlike an earthquake, this won't last more than a second or two."

"But I can assure you that this weapon is ten thousand times more lethal than an earthquake! Anyone caught in the killing range of this grenade will have absolutely no chance of survival. So when you use it, you must be extremely careful!"

"Don't use these things to accidentally injure your colleagues. Instead, use them against the enemy and make sure they never return!"

As soon as Yun Wanwan finished speaking, even Xiao Song, who usually kept a straight face, stared at the scene with wide eyes. Ge Zichen even ran forward to inspect the scene, and when he returned, his face was filled with horror. "Princess, I've checked the area. If we just stand still, at least dozens of people would be affected. Your weapon has a very large killing range!"

He said so, but his eyes were filled with immense shock. "If this thing were really used on the battlefield, there would be no need for Your Highness's formation! Our men wouldn't even have to move, just throw it forward. No matter whether the enemy team has a Dragon Swallowing Formation or a Phoenix Swallowing Formation, we can send them straight to hell for a good meal!"

Yun Wanwan shook her head and gestured to Ge Zichen, "You miscalculated. This should be at least the number. If I increase the dosage of some ingredients, it won't be just this number."

She looked at Ge Zichen and said, "I didn't bring many grenades, only about thirty. I'll give them to you to try out. If they work well, I'll go back and make more."

"Princess, it goes without saying. We're definitely good at using it!" Yun Wanwan had just finished speaking when Ge Zichen immediately followed up, "This weapon is so destructive. Even if we don't know how to use it, we have to learn it with all our might. We'll be the ones running away to get beaten by those Western Zhou people."

"Don't be so confident, but if you can't learn it, I have other weapons I can teach you. This is the simplest weapon among them, but it's also the one most likely to accidentally injure one of our own."

Yun Wanwan returned to the carriage as she spoke, pulling out another type of landmine. Like the hand grenades she'd crafted, the landmine in her hand was a simplified version. After all, she wasn't a professional by trade, so the fact that she could craft these weapons under the harsh conditions of ancient times was already impressive.

Yun Wanwan thought that if her chemistry teacher knew that she had such a skill, when she applied for university, he would definitely want her to choose chemistry as her major so that she can serve the country in the future.

She told Ge Zichen, "This has a similar lethality to a hand grenade, but the difference is how it's used. It's buried underground. Just dig a shallow hole, put it in, and cover it with soil. If someone walks over it, or is crushed by something heavy, it will explode immediately. Just like a hand grenade, if you're within its range, you're dead."

As she spoke, Yun Wanwan handed the mine to Ge Zichen and instructed, "Take it now, run away, and try to bury it somewhere safe from us. Remember to keep a distance. Don't bury it too close, or we'll be the ones to die."

Ge Zichen took the mine from Yun Wanwan's hand, held it carefully and did as Yun Wanwan said. After seeing the gunpowder bombs and grenades, the soldiers gradually stopped being afraid and were now waiting with bated breath to watch Ge Zichen's experiment.

Ge Zichen ran to a safe distance where Yun Wanwan nodded, then he immediately took out his sword and dug a small hole in the ground. Then, according to what Yun Wanwan had just said, he carefully buried the mine in the hole and gently filled it with soil.

After covering it with soil, Ge Zichen looked at it for a while. When he was sure that the mine really wouldn't explode for no reason, he ran back to ask Yun Wanwan, "But Princess, how are we going to test this mine? It's buried there, so far away from us. We can't possibly find someone to step on it and see what happens. That's not very realistic at all!"

Yun Wanwan laughed. "It's not very realistic. You all come from good families, and you have families to support. Du Yuhou was right just now. We can't just find someone to step on it and see the effect. It's really not realistic. So since I was the one who suggested showing everyone the effect, I'll be the one to test it."

After Yun Wanwan finished speaking, she started walking towards the direction where Ge Zichen had just buried the landmine, as if she really wanted to use herself to test it and show them what the effect of the landmine was.
