――――――――――――――

The night of Kaifeng was extremely cold, but Zhao Dezhao was hot, he had vaguely read books such as "Encyclopedia" and "Ji Xiao New Book" in his previous life, he naturally knew the ratio of black * fire * medicine, and after recalling it in his mind for a while, Zhao Dezhao wrote down the formula on the paper with a pen:

one tael of nitrate, one coin of yellow, four points of willow charcoal, one coin and eight cents; A total of 40 taels of nitrate, 5 taels of yellow and 6 coins, 7 taels of willow charcoal, and 2 bells of water, it is wonderful to lick it very finely.

Secret method: first grind the nitrate and yellow charcoal into the end, mix it with one place, and use two bowls of water in the wood and pestle. Those who don't use stone hyenas are afraid of fire. Each of them can be ten thousand pestles. If it is dry, add a bowl of water and then scoop it to the degree. Scoop half dry, take the sun, crush into bean grains, this medicine is wonderful, only more than tens of thousands of pestles.

According to this formula ratio, it can be seen that nitrate is 75.75%, sulfur is 10.60%, and carbon is 13.64%. The ratio of black * fire * medicine is close to that of later generations is 75%, sulfur 10%, and willow charcoal 15%.

When it was dawn, Zhao Dezhao instructed his confidants to purchase materials between the Chinese medicine stores and grocery stores in the city according to this recipe ratio, and then transported them to the ordnance prison by horse.

At this moment, Zhao Dezhao was in the dust, and he was also rushing to the ordnance superintendent, and the new gunpowder superintendent, the deputy envoy of the workshop, Wei Pi, and dozens of craftsmen were already waiting in the ordnance superintendent.

After Zhao Dezhao arrived at the Ordnance Prison, Wei Pi and dozens of craftsmen visited King Chitose of Liang.

Zhao Dezhao shook his robe, and said solemnly: "Everyone, what you are doing today is very dangerous, and you should not go near the source of fire or heat according to what I said later, and today this king will share weal and woe with everyone, and share weal and woe." If today's thing is successful, you will be the heroes of the Great Song Dynasty in the future, your family will be proud of you, and the people of the Great Song Dynasty will be proud of you! ”

"Your Highness—" Several craftsmen burst into tears after hearing this, and were very moved, in their minds, the prince was high, how could there be a connection with them, the poor people, and the His Royal Highness King Liang they saw today was not the case at all.

"Get up, Your Highness has something to tell you later!" Wei Pi instructed a few people to follow the process written in the recipe to hurry up and make it, and then try to avoid improper operations. Because of its full preparations, craftsmen were strictly ordered not to operate near fire and heat sources, for fear of explosion, and these 500 soldiers of the forbidden army were stationed outside the house.

Inside the house, the atmosphere was tense and orderly, under the personal command of Zhao Dezhao and Wei Pi, the craftsmen weighed the purified nitrate, willow charcoal and yellow [sulfur] according to the ratio provided by Zhao Dezhao, and then ground them into fine powders respectively, and then according to the method provided by Zhao Yan, in order to prevent accidents, they were first wet with water and mixed together.

The atmosphere of the craftsmen was tense, and they were always on guard, Zhao Dezhao had already stated the danger of this matter at the beginning, so the craftsmen were all worried about the operator, lest there be a case.

But when they saw Zhao Dezhao, who was the king of Liang, put down his body and operated with them, this nervous mood had relaxed a lot, and after operating, he secretly admired the spirit of King Liang, and felt that King Liang was also a human being, and he was really approachable to be with these ordinary people today.

The gunpowder was already wet, and together, it looked like a lump of black-brown mud, and Wei Pi ordered people to support drying in ventilation and shade, the weather in December was cold, and the sunlight was weak, Zhao Dezhao asked people to bring a fan to fan on the side.

The craftsmen spread the gunpowder mud very thinly on trays, and it took a day to wait for it to dry in the winter, and the next day the gunpowder was dried in the sun, and then crushed into small particles, and then a shell made of iron sheets was brought and loaded into it, which was a grenade.

After two days of continuous production, all the work is done, waiting for the final test link. This time, a total of thirty finished grenades and ten gunpowder pills were produced, that is, test products, and waiting for their power must be let today's son Zhao Kuangyin witness its terrifying and destructive lethality. As for the test, Zhao Dezhao temporarily returned to the palace to tell Zhao Kuangyin before making a decision.

When he arrived at the Funing Palace, Zhao Dezhao saw Zhao Kuangyin and said: "Congratulations to my father, congratulations to my father, gunpowder has been made today, and it took the efforts of dozens of craftsmen in the Ordnance Supervision for two consecutive days. ”

Zhao Kuangyin just reviewed the folds. As soon as he heard that the gunpowder had been made, he hurriedly put down the pen, and the Zhu pen had already been scratched, Long Yan said with great joy: "Zhao'er, this is great, is what you said true?" Come to someone, go and inform a few Zaifu, tomorrow morning to drive the forbidden land of the Chengxi Government Office, I want to see it with a few Zaifu in person! ”

"Yes!" The chamberlain immediately sent the decree down, and went to the mansions of Wang Pu, Fan Zhen, Wang Pu, Wei Renpu, Miao Xun, Zhao Pu and Zhao Guangyi to deliver the decree, and tomorrow went to the forbidden place of the official office in the west of the city to watch the gunpowder show.

After receiving the command, they prepared their testimonies for tomorrow.

Early in the morning of the third day, Zai Fu and several people, the emperor and Zhao Dezhao all came to the forbidden place of the official office in the west of the city.

This place is located in the northwest corner of Tokyo outside the Tianbo Gate, deserted, there is no household around, and a radius of ten miles belongs to the forbidden land of the official office, without the consent of the imperial court, no one is allowed to enter, and the forbidden soldiers are always guarding around, not only to guard the secrets here, but also to prevent accidents at any time.

There was still a wasteland around, Zhao Dezhao ordered people to buy a few poultry and a few pigs, and then placed them on the open field, and the people around did not know what kind of gourds Zhao Dezhao was selling in the gate.

At this moment, the soldiers of the forbidden army transported hand * grenade * bombs and gunpowder pills and pulled them over, Zhao Dezhao ordered to bring a lead, and then took out a hand * grenade * bullet from it, and then tied it to the hand * grenade * bomb, so that people can operate from a long distance, and tie a chicken near the hand * grenade * bomb.

"Father, all the ministers, you are all hiding far away, it is not safe to get too close!"

Zhao Dezhao asked the surrounding people to stay away, then covered his ears, and then ordered someone to take out the fire fold, light the fuse, and the sneering sound burned inch by inch, and soon burned to the lower part.

Suddenly there was a "boom", the whole ground shook, dust splashed, a chicken around the body was already incomplete, blood was splashed, flesh and blood were blurred, the ground where the grenade was located, only to see that the soil on the ground had been blown up, revealing the soil below, and the surrounding ground was also black, exuding a strong saltpeter smell.

Zhao Kuangyin and several Zaifu, soldiers, and craftsmen who had never seen this power smelled this smell and quickly covered their noses. At this moment, they were all dumbfounded, still amazed and frightened by the thrilling scene, and after the bomb, a small crater was already sunk in the ground, but this was only the power of the hand * grenade * bomb, and the hand * grenade * bomb was also mixed with some ceramic fragments and iron nails, so Fang just let everyone hide far away, otherwise they would be hurt by it, and there would inevitably be a big scar on the skin.

And Zaifu, who had not yet made up his mind, and Zhao Kuangyin, who shouted that this thing had such power, all stared at the ball-like object with frightened eyes, and this thing was the size of a small cold melon.

Zhao Kuangyin saw its huge size, and asked suspiciously: "Zhao'er, is that object the most powerful!" ”

"What my father said is very true! This thing is called a bomb, but now the weapon that relies on it has not yet been made, this thing is sleek, like a small cold melon, and when you weigh it, you also feel that this thing is very heavy and abrupt. ”

"Zhao'er, try that one too!"

"Yes, Father, Zhao'er immediately let people test its power, and let everyone witness its terrifying power."

Soon, Zhao Dezhao immediately said to the people around him: "This thing is more powerful than the *grenade* bomb in his hand, I don't know how powerful it is, you all disperse, let me light one to try the power." ”

"Your Majesty, it's dangerous, let's let the ministers try!" It was a junior general of the Forbidden Army who spoke.

Then, according to the previous operation, the young general lit the fuse, and then the people around him hid far away, and the young general covered his ears and fled.

"Boom-" There was a loud bang, the earth shook, and the surrounding dust was splashed, and at this moment, in Kaifeng, the palace buildings, mausoleum halls, houses, etc. all shook.

"The earth dragon has moved—" everyone said in unison.

Then the people were terrified, and some of them rushed out of the houses before they were dressed, and everyone went outside, and everyone agreed that it was an earthquake, but soon the houses were still standing, and the earthquake did not come, and after a long time, they all went back to the house in great fear.

And at this moment, the forbidden land of the official office in the west of the city, everyone was surprised, this shocking was beyond the scope of people's imagination, and Zhao Dezhao also felt that this sound was very shocking, such as looking at the ground, even more than Fang Cai, a huge pit appeared in front of everyone, and the pig was already torn apart.

Some of the timid people had long since looked like dirt, and when they saw that the live pigs were dead, they all sat on the ground, and they had not stood up for a long time.

"Long live Your Majesty-" Several Zaifu knelt on the ground at the same time, and then the soldiers of the forbidden army also knelt down, and Zhao Dezhao also followed behind everyone.

"Flat! You have just seen the power of gunpowder, this thing can be used as an armament weapon of my Great Song Dynasty in the future, and it is expected that once this thing comes out, it will definitely shock the world. Today, I tried it here again, and it was really beyond expectations, and since this thing is owned by my Great Song Dynasty, it must be kept secret, otherwise it will spread out and there will be endless harm. Zhang Dejun, spread my will, nothing can be passed on today, if you let me know who passed it out, you will bear the consequences! ”

When Zhao Kuangyin said the last sentence, his face was resolute.

Zhao Kuangyin's words made everyone hold their breath, and at this moment Zhao Kuangyin continued: "King Liang is the biggest hero in this matter, and he is specially appointed as the supervisor of the ordnance supervision, and the deputy envoy of the workshop, Wei Pi, is meritorious and promoted to the workshop envoy, and the rest of the craftsmen are rewarded with ten taels of gold per person and three days off. ”

"Thank you, Your Majesty!"

Zhao Dezhao didn't expect that because of the gunpowder incident, Zhao Kuangyin asked him to serve as the first envoy of the ordnance supervisor, and was fully responsible for the supervision and improvement of the ordnance equipment, and at this moment, Wei Pi also glanced at His Royal Highness King Liang affectionately, and expressed his willingness to serve the dogs and horses.

And in the crowd, Zhao Guangyi's eyes flashed with a different meaning and a trace of resentment, but fortunately, he concealed it very deeply, and no one could see it, but Zhao Dezhao caught a trace of information, it seems that his third uncle is already envious, jealous and hateful of himself!

But what is the way to do this, at the original moment, but this uncle sat on the throne, so in this life he does not intend to let Zhao Guangyi's treacherous plan succeed, what "Golden Alliance", "axe and candle shadow", all are gods, as long as they are strong, will they be afraid that history will repeat themselves, people live for a lifetime, isn't it just to work hard for their own ideals!

However, Zhao Dezhao suddenly felt that his change did not make this third uncle change much, and Zhao Guangyi, who was originally reused in history, was always covered up by Zhao Dezhao's amazing performance as if he was unknown, and Zhao Dezhao didn't know if Zhao Guangyi would become a cold-bellied black man like in history, so it was better to be on guard in secret.

And power is the most corrupt to a person, fortunately, the power that Zhao Guangyi is in contact with now is not the core, Zhao Dezhao is so preemptive and establishes his own power, but also for his own survival and ideals, and it must be saved so that Zhao Guangyi does not touch power.

Today's incident made the ministers change their views on the war, it turned out that the battle could still be fought like this, and Zhao Dezhao's successful gunpowder production also made the war more intense and more intense, maybe Zhao Dezhao would feel that he was doing this, just to make history more advanced, to make the original difficult things simpler.

And around the war link, Zhao Dezhao did only insignificant things, and now other things can only be carried out slowly, I believe that soon, what he expects can also be realized.

At this moment, in winter, the strong winter monsoon is blowing, and the flow of coastal currents is stronger, and it can flow out of the Taiwan Strait into the South China Sea along the coast. Now that they had avoided the current, the Wansong fleet had crossed the Penghu Islands and headed north around the west coast of Liuqiu.
