Zhou Jia smiled and found a video, but this time the video was very simple. It just showed a man carefully burying a round object with a line extending into the distance. The man took out a small red wooden stick and scratched the side of the box. Immediately, a small flame appeared and the line was ignited.
Everyone didn't understand what was going on and looked confused.
While Ying Zheng and others were curious about the round object, they were also wondering about the fire-making box, which looked very convenient to use.
The scene that appeared next was enough to make all of them breathe and their heartbeats quicken.
As the fuse burned out, there was a sudden and violent explosion in the distance, followed by flying dust. Many trees around were destroyed, and it took a while for the ground to return to normal.
Ying Zheng and the others jumped up from their seats excitedly when they saw this scene, "Sharp weapon!"
Wang Jian and other generals were envious. "If this kind of artifact can be used on the battlefield, it will surely reduce our casualties!"
But then they thought of another problem, "No, Miss Zhou Jia's screen is broadcast regardless of race. Those Xiongnu people can naturally see it too. If they get the upper hand..."
Ying Zheng naturally thought of this, but he had no way to ask Zhou Jia to stop playing it.
Except for the dynasties that came a little later, the earlier dynasties had similar thoughts to Ying Zheng and his men when they saw this scene. The Huns and others naturally also paid attention to this and were very happy.
Maodun laughed loudly, "Hahaha, since this girl mentioned this, then next, it depends on us or those Han people who can master these things first!"
Zhou Jia could naturally guess what was going on, so she smiled faintly and asked, "Do you like it? Is it exciting? Do you want it?"
Ying Zheng couldn't help but nodded, and Wang Jian and the others nodded even more.
Like! Exciting! Want!
"Let me show you another video."
This video was different from anything they had seen before.
The person on the screen was Zhou Jia, holding a long and thin object in his hand and shaking it. The colors were changing. Then another person lit something, and there was a crackling sound. What was even more dazzling was the last thing that was lit. After two bangs, fireworks of various colors bloomed, dazzling and colorful.
This is a video Zhou Jia took during the Chinese New Year.
Zhou Jia snapped his fingers, drawing everyone's attention to himself.
"The one in front is a bomb, but it's a very old model. There are many newer ones now. The one in the back is a firework, usually used during festivals. Both of these things contain gunpowder. Let's first look at the history of gunpowder."
Ying Zheng sat back in his seat and listened attentively to Zhou Jia's words. Although he was eager to know how to make this thing, it would not do them any harm to know more.
"When I was talking about His Majesty, I mentioned one thing. Many people say that His Majesty has taken elixirs. Feng Zhu has also taken them, right?
Pills, those alchemists all say that eating this stuff can make you immortal. They refine pills for the emperor day and night. When refining pills, it is impossible to succeed every time. There must be a few times when the pills fail to be refined, and there may even be cases where the alchemy furnace explodes. So, alchemists, does this explosion feel familiar to you?"
Ying Zheng looked at the eunuch beside him and said, "Bring those people up here!"
Ever since Zhou Jia gave his instructions, he has brought all the sorcerers under control. He only needs to ask them directly if the situation Zhou Jia mentioned exists.
However... the explosion of this alchemy furnace is indeed somewhat similar to the bomb explosion above.
"Could it be that there is gunpowder in the alchemy?" Liu Ji said excitedly.
Meng Tian narrowed his eyes and patted him on the shoulder, "You really want it."
Liu Ji's body stiffened, and he looked at Meng Tian's serious face and laughed dryly.
"How could that be? I'm doing this for the pleasure of His Majesty and the Great Qin. If that were the case, those alchemists would be able to try..."
His voice became lower and lower, and Meng Tian's eyes became colder and colder. Liu Ji's shoulders were so painful from being grabbed that his bones were about to break.
"His Majesty……"
He looked at Ying Zheng with a sad face.
He only now realized a problem, the most terrible thing about the Great Qin was the courtiers below who were smiling all day long, while the one sitting at the top with a cold face who looked like he was not easy to mess with was the most gentle one!
Ying Zheng glanced at Meng Tian, with a hint of smile in his eyes, and was in a very good mood. "Okay, Meng Tian, don't scare him."
Meng Tian let go of his hand with a sense of grievance, "Yes."
Wang Jian and Meng Wu watched these little ones playing without stopping them, and just laughed beside them.
Their minds are full of gunpowder now, and nothing else matters. Even if Liu Ji really has some thoughts, they can just destroy him, right? Anyway, the person is in front of them.
Soon, the alchemist was brought to the palace and knelt down upon entering. "Your Majesty, please spare my life. Miss Zhou Jia is right. There have indeed been cases of alchemy furnaces exploding in the past."
Everyone was trembling and didn't dare to look up. Ying Zheng got a satisfactory answer and looked up at the sky.
"Unfortunately, those alchemists only thought about how to achieve immortality and did not pay much attention to these explosions. However, when it came to military strategists, gunpowder became a weapon of great destructive power.
Before the appearance of gunpowder, some people had already wanted to use fire attacks. After the appearance of gunpowder, due to its large killing range, it was naturally used and studied by many people.
During the Tang Dynasty, people used catapults to hurl gunpowder bags instead of stones and grease fireballs. During the Song Dynasty, gunpowder developed again, and firearms such as rockets and fireballs were also used.
