Chapter 623 Blown Away
"Xu Congcong, would you like to add two chicken drumsticks to dinner?" Lin Ping cleared his throat and asked seriously.
Upon hearing this, Xu Congcong... showed no interest whatsoever, but in order to please Lin Ping, she pretended to be overjoyed, nodding like a chick pecking at rice, and hurriedly said, "I want to! I really want to! I dream about it!"
"Then let me test you. If you answer correctly, I'll give you a chicken leg!" Che Nu said, squinting his eyes.
Test Xu Congcong? Are you sure you're not asking a question?
"I know I am not very talented, so please ask the dean to give me a simple question." Xu Congcong chuckled, not revealing Lin Ping's purpose even though he saw through it.
"You're on the right track!" Lin Ping nodded in satisfaction and asked, "Tell me what kinds of stones the Wu Kingdom has that can be smelted."
Lin Ping didn't believe that Xi Shi hadn't appeared; he must have been using a different name that he just couldn't remember right now.
"Gold, silver, copper, iron, aluminum, lead, He stone..." Xu Congcong rattled off a string of names, constantly observing Lin Ping's expression, afraid of missing anything.
"Wait, what kind of stone is the last one?" Lin Ping asked curiously.
“He Shi!” Xu Congcong replied.
"I remember now! Song Yingxing said in 'Tiangong Kaiwu' that tin was called 'He' in ancient books. Haha, He stone is tin stone!" Lin Ping jumped up and down excitedly.
Several students stared at Lin Ping in surprise, mistakenly believing that Lin Ping had taken stimulants.
"Hmm, that's a good answer. If we can buy some He Stones before dark, we can have chicken legs for dinner." Lin Ping tried to calm himself down and took out a silver note.
This is a hundred taels of silver. Xu Congcong sucked on the silver note several times and rushed out like lightning.
Although the Wu Kingdom did not have He Stone mines, the Daye Dynasty had abundant He Stone resources and often engaged in commercial transactions with the country, purchasing a considerable amount of He Stone.
One hundred taels of silver could definitely buy a cartload of He Shi, and Xu Congcong wouldn't be foolish enough to spend all of it.
He guessed that Lin Ping wouldn't need that much money, so wouldn't it be better to secretly keep some to buy chicken legs?
It wasn't until evening that Xu Congcong led two porters into the academy.
Lin Ping was quite satisfied with the baskets of tin. He didn't bother asking Xu Congcong for the remaining silver coins and hurriedly began the next experiment.
To facilitate research, there was a kiln in the academy, and Lin Ping put charcoal and tin together into the furnace.
Thinking about the upcoming great battle, Lin Ping was eager to manufacture cannons immediately.
The X-ray machine was turned on directly to observe the condition of the tin ore inside the furnace.
As the furnace temperature rises, the tin begins to melt slowly, and many impurities are burned away by the flame.
However, after half an hour, the melting speed of the tin slowed down significantly, and it could not even be completely melted.
"As Mr. Song said, when the heat is high enough, the sand will not dissolve immediately. Only by using a little lead to lure it can it flow freely." Lin Ping recalled the contents of "Tiangong Kaiwu" and felt admiration.
Lin Ping immediately found some lead blocks and put them into the furnace. Sure enough, the unmelted tin turned into liquid.
After the tin had completely melted, Lin Ping poured the liquid into a porcelain bowl and quickly poured it between the two iron plates.
As the temperature dropped, the molten tin slowly solidified, and the two iron plates were firmly bonded together, just like a single unit.
"Hahaha! It worked!" Lin Ping cheered, while the students next to him were at a loss.
Isn't it just welding two iron plates together?
Is it really necessary to be so excited?
"Go get the high-speed iron plate again. I need to weld it into a spherical shape," Lin Ping said anxiously, wanting to test the power of the iron armor bomb immediately.
Several students brought over an iron plate, and Lin Ping continued to pour molten tin on it, successfully welding the iron plate into a spherical shape, leaving only a small hole at the end for filling with gunpowder.
"Where's the gunpowder? Bring it all here. Today I'll show you the true power of gunpowder," Lin Ping said excitedly.
Gunpowder is only gunpowder when it is filled with iron; otherwise, it is just a firework.
"Will this iron ball covered in patches work?" Xu Congcong wondered as he watched Lin Ping carefully load the gunpowder.
He had also seen welding techniques before, most of which were not very strong, and were only as effective as glue. He did not think that this would be more powerful than a stone-coated bomb.
"When loading gunpowder, you must use a wooden pestle. If you use an iron pestle instead, you're not far from death," Lin Ping said earnestly.
When an iron pestle collides with gunpowder, it could very well explode.
Holding a burning bomb in one's hands, the consequences are predictable.
The group nodded vigorously, taking Lin Ping's words to heart.
Before long, the gunpowder was loaded, and the bomb was complete in the true sense of the word.
Lin Ping found a three-foot-long fuse and then placed the bomb in the most open space.
"Make way, and tell all the students not to panic no matter what happens," Lin Ping hurriedly instructed.
These people could see Lin Ping's seriousness, and quickly relayed the message.
The more Lin Ping said this, the more curious the students became. Dozens of them surrounded Lin Ping, waiting to see a miracle happen.
No one should be within three hundred feet, and everyone should be lying on the ground.
The students lay trembling three hundred feet away, their eyes wide as they stared at the dark bomb.
As the last rays of the setting sun gradually faded, night replaced day, and oil lamps lit up one by one inside Huiwen Academy.
Lin Ping held a bright tinderbox in his hand and slowly approached the bomb. The flame flickered next to the fuse for a long time, but he dared not light it no matter what.
"Let's give it our all!" Lin Ping mustered his courage and shouted, "Xu Congcong, you order!"
After saying that, Lin Ping ran to the back of the crowd and lay down on the ground like a little mouse, even covering his head with his hands.
Xu Congcong was terrified, but he couldn't disobey the order. His arm holding the tinderbox trembled uncontrollably, and he didn't even realize he had lit the fuse.
The moment the fuse was lit, it burst into flames at a speed far exceeding Lin Ping's expectations.
"Are you an idiot? Run!" Lin Ping shouted angrily, genuinely worried for Xu Congcong.
"What? It's already lit?" Xu Congcong's legs went weak with fright as she watched the sparks on the fuse rapidly approach the gunpowder.
"This is trying to kill me!" Lin Ping, who had been lying down, quickly stood up and rushed towards Xu Congcong like lightning.
With his Black Lotus Realm strength, his speed was comparable to a gust of wind. In just a few breaths, he had arrived beside Xu Congcong, grabbed his arm, and ran.
However, the rapidly burning fuse had already penetrated the armor and was about to detonate the bomb.
bump!
In the darkness, a bright white lotus flower bloomed. The iron armor covering the gunpowder could not withstand the immense pressure and was instantly torn into pieces, flying erratically in all directions at a speed exceeding that of a crossbow bolt.
At the same time, the shockwave from the bomb spread out, creating a deep crater in the ground, and the whole yard was filled with continuous "booms".
The students lying on the ground were disheveled by the blast wave, and their hair was completely disheveled.
"Oh no! The dean and Xu Congcong were blown up!" a student said, pointing to the sky.
