Zhao Sanpao's words made Li Yuanba's brows furrow.

Isn't that right? Could it be that I am mistaken?

No, the first book in China to record the formula of gunpowder was written in the eighth and ninth centuries. In the book, it is said that "sulfur and realgar saltpeter are combined and burned tightly", and the phenomenon of "flames rising, burning hands and burning houses" will occur.

According to the calculation of time, Datang should also have black. Gunpowder is right.

Forget it, it's useless to entangle this thing, fortunately, in his previous life, in order to be able to enter the ancient tomb justifiably, Li Yuanba once taught himself to get a postdoctoral degree in archaeology, so for a proficient, or familiar with the master of digging tombs and robbing tombs, the configuration is black. Gunpowder, that couldn't be easier.

Think about making zuò fire. The raw materials needed for medicine are saltpeter, sulfur and charcoal, and the details that need to be controlled are nothing more than the proportional distribution between them, as long as they are properly distributed, Li Yuanba even feels like Archimedes, give him some raw materials, he can blow up the whole earth.

After asking Zhao Sanpao, these things were really available in Datang, and sulfur was ridiculously available in Chinese herbal medicine stores.

Immediately ordered his subordinates to prepare a fire. The raw materials of the medicine, Li Yuanba asked Zhao Sanpao to get some charcoal, and then asked the eunuch in the palace for a Chinese medicine store, the kind of small one used to catch medicinal materials, and the next thing is simple, and after the raw materials are in hand, he directly sharpens the knife Huo Huo Kai.

By the time the servant who had gone to buy the sulphur returned, it was already a quarter of the hour, and because it was winter, it was already dark.

However, at this moment, Li Yuanba was very interested, and when all the raw materials were placed in front of him, he started directly, and after grinding back and forth for half an hour, he finally prepared a small porcelain pot of gunpowder.

"Three cannons, you can fill this thing in later, and then burn it and try it!"

He was about to hand over the freshly baked gunpowder from the small porcelain basin to Zhao Sanpao, but when Li Yuanba understood the indifferent expression on Zhao Sanpao's face, he suddenly felt that his heart was very unsteady.

After thinking about it, Li Yuanba brought back the small porcelain basin and said, "No, I'll do it myself!" ”

Zhao Sanpao said with some hesitation: "Lord Wang, can this thing really sound?" ”

Li Yuanba rolled his eyes and said, "You removed the word '?', this thing is really loud!" And ten, a hundred times louder than your blasting rod...... Forget it, you don't believe it, let's show you how powerful it is! ”

Speaking of this, Li Yuanba directly took a section of dried bamboo pole from the outside, carefully scooped up about twenty or thirty grams of gunpowder with bamboo slices, and poured it into one end of the bamboo pole, and the other end was also administered according to this method.

After that, Li Yuanba found some strips of torn linen cloth and directly blocked the two ends of the blasting rod.

"Lord Wang, what kind of gunpowder are you putting too little, right? In this case, the blast rod will not go off! Zhao Sanpao felt very strange when he saw Li Yuanba so cautious.

"Less? That's it, I'm afraid of putting too much! Li Yuanba shook his head, and simply walked out with the blasting rod filled with gunpowder.

The two bamboo joints of the blasting rod were each filled with 20 grams of gunpowder, and even the famous 'cupola cannon' (also known as 'two kicks') in later generations did not dare to put so much.

You know, from time to time, people will be disabled when you put a cupola cannon, not to mention this blast rod made of bamboo poles. If it weren't for the test of its power, Li Yuanba wouldn't have put even 20 grams of gunpowder in it.

"Xia'er, Jingjing, all of you stand far away! Although this thing has just been trial-produced, it should be extremely powerful, you two stand far away, don't look back, the bamboo pieces will collapse and hurt you! ”

Li Yuanba turned his head and instructed the two women, and after lighting a torch and putting it on the ground, he ran to the side, and threw the bamboo pole in his hand towards the torch from a distance.

The bamboo pole had just been pressed against the fire, and it had no effect.

One minute, two minutes......

When it was the third minute, Zhao Sanpao walked towards the torch with a single step, and at the same time said: "Lord Wang, I'll go over and see ......."

"Boom!"

Halfway down the road, before the words were finished, a deafening loud bang came from directly ahead.

Then, I saw that the whole torch was exploded by the bamboo pole, and in an instant, it was blown up in all directions, and the smoke and ash of sparks filled the entire courtyard.

In the garden, the flowers and plants that were quite pleasing to the eye were completely disfigured by the scattered bamboo knots, and became remnants of flowers and willows.

The qiē in front of him happened so suddenly that Li Yuanba only had time to pull the two girls to hide behind a pillar, and his ears were buzzing.

The most unlucky is Zhao Sancang, this is the closest to the bamboo pole stuffed with gunpowder, if it weren't for its five big and three thick, I'm afraid it would have fallen to the ground a long time ago.

After a long time, wiping a handful of black faces stained by scattered soot, Zhao Sanpao swallowed his saliva hard, and muttered in his mouth: "My mother, this, this is much more powerful than a blasting rod!" ”

Li Yuanba saw Zhao Sanpao standing still in place, and thought that something had happened to him, as soon as he walked to his side, he heard this sentence, and couldn't help but smile, and said, "Sanpao, I said it before, right?" This thing is very powerful, you don't listen, now it's okay, look at the way you look now? ”

"Uh......"

Zhao Sanpao looked at his big black hand and laughed.

"Quick, quick, over here!"

"What happened?"

"Why is there a thunder in the palace!"

At this moment, with the west road across the courtyard as the center, there were bursts of discussion and slightly noisy footsteps in all directions.

Soon, the arch of the west courtyard was crowded, and one by one, they all looked inside.

Li Yuanba frowned when he saw this, and said, "What do you see?" It's none of your business here! What to do, what to do! ”

"Yes, Lord Wang!"

Seeing that it was his own prince in the West Cross Courtyard, the maids and eunuchs in the palace respectfully saluted him, although he was extremely puzzled, but he still had to leave, but the prince's army stayed.

Su Dingfang, the leader of the guards, who was still wearing soft armor, looked at the messy courtyard, stepped forward and saluted: "Lord Wang, ...... here"

"Well, it's fine, it's just a little bit of a gadget!"

I got the number I wanted in my heart, and Li Yuanba didn't want to tell outsiders about this matter now, after all, this matter involved the fate of the country, and if such a department could be established to specialize in research and use of gunpowder, then this thing would really become a weapon of war.

When the time comes, what Xue Yantuo, Turkic, and Tibetan people will directly bombard them to death with cannons, where is there any need to be friendly and suffer from this bird's anger!
