The prince is very cruel

On the other side, Guan Ning started again.

This time, he carefully controlled the temperature. After all, this thing would easily explode when heated. Fortunately, it was only saltpeter. If the finished black powder exploded, the consequences would be disastrous!

After a full quarter of an hour, Guan Ning was already sweating profusely, with a cloth covering his mouth and nose, and his eyes fixed on the utensils. He would immediately hide if he saw anything wrong.

But fortunately, after a failure, this time I finally succeeded.

After setting the finished product aside to cool, he turned his attention to the sulfur.

This thing was found in a Taoist temple. It seemed to have been used by someone to make elixirs. There were some signs of processing, but it was far from the effect Guan Ning wanted.

He followed the same method and used heating to extract sulfur.

This thing is much safer than saltpeter and is not afraid of explosion, so it can be processed quickly.

As for charcoal, it does not need to be processed and can be used directly.

On the table, a small portion of crystallized saltpeter, a small portion of sulfur, and a small portion of charcoal were quietly placed.

At this time, Guan Ning's expression became much more serious. He poured the three things together according to the proportion, and then crushed them gently with a wooden mallet until they were completely blended.

Thus, the first black gunpowder of the Wu Dynasty was born!

Guan Ning was excited and couldn't help but want to test its power.

With skillful techniques, he put everything into a jar, stepped on it firmly, covered it with a layer of yellow mud, and placed the fuse prepared in advance into it.

These steps may seem ordinary, but in fact, every step must be correct. If there is even the slightest mistake, the black powder will become defective and it will be difficult to achieve the killing effect.

It was already afternoon by the time the yellow mud had completely dried up, fixing the gunpowder inside and allowing it to generate sufficient squeezing pressure.

Guan Ning jumped into the deep pit that had been dug in advance and took a deep breath.

"God bless you, please don't let me down!"

"The material is a bit inferior, but after all, I don't have sophisticated machine tools, so I rub it completely by hand. I just need enough power to blow the stone over."

He muttered to himself, then opened the tinderbox and lit the fuse with great solemnity.

The fuse was neither fast nor slow, and was just made by Guan Ning using wool and black powder. It made a hissing sound as soon as it was ignited.

This familiar voice even brought Guan Ning back to his previous life. He habitually lay down and hugged his head, doing it in one go and smoothly.

One second, two seconds, three seconds, four seconds...

More than ten seconds passed, but there was no movement at all. Guan Ning's expectant eyes couldn't help but become a little confused. Could something have gone wrong?

He stood up tentatively.

Just stood up, the next second, bang! !

There was a loud bang, and the calf-sized vessel disintegrated, spewing out tongues of fire, like a thunderclap out of the blue.

A powerful air wave rushed towards Guan Ning. His pupils widened and he had no time to react. His body flew backwards and hit the ground with a heavy bang.

The people a hundred meters away were startled by the noise, thinking it was thunder.

"Guan Ning!"

Lou Xinyue was the first to rush out, followed closely by Hai Mei.

The two girls looked unhappy because they saw Guan Ning flying out with their own eyes.

"Guan Ning, how are you?"

"What's going on?" Lou Xinyue panicked.

Guan Ning was helped up, coughing violently, his ears buzzing, and it took him a long time to hear anything. His face was covered in black and gray, and he shook his head: "Cough cough cough..."

"It's okay, I'm okay!"

"Damn it, there was a small mistake and the explosion was delayed. Luckily I didn't get close, otherwise you would have become widows." Guan Ning cursed, his face was dark, but his teeth were snow-white, which was extremely funny.

Lou Xinyue and the other girl breathed a sigh of relief, and then both laughed and cried at the same time.

Guan Ning stood up despite the severe pain in his back, waved his arms, and stared intently into the green smoke.

Luo Zhongtian and others also rushed over and clearly smelled a pungent odor.

When the green smoke dissipated, everyone was dumbfounded with their eyes wide open!

I saw that the previous table was overturned and broken into pieces. Not only that, a big hole was left in its place, which was completely black and turned into charcoal!

"Was this struck by lightning?" Luo Zhongtian couldn't believe what he saw.

Guan Ning grinned, very satisfied with the power.

"This isn't thunder from the sky, it's the power of black powder!"

Hearing this, everyone was shocked!

"Black powder?"

"so smart?"

"If someone stood next to it, it would fall to pieces!" Hai Mei was surprised, and an egg could fit between her red lips.

Guan Ning laughed and said, "That's nothing! As long as the dosage is increased, not to mention this small pit, even a mountain can be flattened!"

Boom!

These words were like thunder in broad daylight, stirring up a storm in everyone's hearts. They had doubts before, but now...

Everyone looked at Guan Ning as if he were a monster.

"I'll try again and hope there aren't any problems. You guys step back!" Guan Ning wanted to ensure the success rate of detonation, otherwise if an accident like just now happened again when it was really used, it would be troublesome.

Delay is not scary, what is scary is that it explodes prematurely and kills you.

"Be careful!" Lou Xinyue frowned, and it looked like she was really afraid of becoming a widow.

"Hahaha!"

"Okay, don't worry, it's okay." Guan Ning said.

Lou Xinyue had no choice but to retreat, looking back every few steps, and he was the only one left at the scene.

He quickly rubbed an enlarged grenade with his hands, using a porcelain bottle as the container. This time he was much faster. In order to make it explode on time, he checked it front and back, not daring to have any errors.

By the time everything was done, it was already dusk and the sun was setting.

Everyone was waiting anxiously, only to see Guan Ning suddenly jump into the deep pit. Everyone became nervous, subconsciously stepped back, and covered their heads.

The entire hillside was silent and time stood still.
