The mountain is not high, there are fairies and spirits.

When Liu Wei and his entourage came to the foot of the mountain where Shi Ziyi's medicine house was located, they looked up and saw that a majestic medicine house was hidden in the middle of the mountain, and it was quite like being in a fairyland under the fog cover of the clouds and mountains.

Originally, Shi Ziyi's medicine house lived near Jincun in the eastern suburbs, and after Liu Wei returned to the palace, he quietly spent money to move the medicine house here. The design of the entire medicine house borrows from the style of Taoist temples in later generations, but there are no temples dedicated to gods, and most of them are alchemy rooms similar to modern laboratories.

Taoist temples only began to flourish in the Tang and Song dynasties, when they were the place where the Buddhist temple was imitated and the foreign product began to be built. Originally, Liu Wei wanted to build a Taoist temple for Shi Ziyi now, but the architecture was already unusual, so Liu Wei didn't want to attract the attention of others anymore, after all, the medicine house was ostensibly for Shi Ziyi to cultivate immortals and alchemy, and the real use was Liu Bian's personal science laboratory.

Papermaking, printing, glass gunpowder, and countless other knowledge and ideas from Liu Bian's past have been repeatedly experimented and verified here. Don't underestimate the Taoists of this era, they themselves have mastered a large number of chemical and physical methods, and Liu Wei has taught them some future chemical knowledge, which is even more powerful. The main thing is that whatever is done here will be cloaked in the mystery of religion. No one will accuse or doubt, everyone will take it for granted, and cultivators have always been mysterious and mysterious.

Walking up the winding mountain road, the road is also flat. In order to facilitate transportation and access, Shi Ziyi repaired this mountain road, and every year he will find someone to repair it, which is also what Liu Wei meant.

Along the way, I met many villagers who went up to the mountains to seek medicine, and Shi Ziyi's Taoist magic powers were well-known near Luoyang. Before coming to the medicine house, Shi Ziyi's disciples had already greeted him from afar, and some people turned around and ran into the medicine house to report.

At this time, Shi Ziyi was supervising his disciple's alchemy, and when he heard Liu Wei coming, he hurriedly trotted out to meet him.

The ancients had premature aging, but Shi Ziyi, who was only over forty years old, had gray hair, a thin face, a long beard hanging down his chest, and he looked quite fairy.

Shi Ziyi was originally a poor scholar in Luoyang, and married a wife and had children in his early years. However, because his wife died in childbirth, and his only son died at the age of one, he left away from the world and practiced alchemy, hoping to find spiritual solace in religion.

Unexpectedly, decades of dedication to cultivation made him quite insightful, and gradually became famous, just in time for the birth of Liu Bian, Emperor Ling of Han, who had already died several princes, was afraid that Liu Bian would not be able to support him, so he handed him over to Shi Ziyi to raise, hoping to use his Taoism to protect Liu Bian's growth.

Shi Ziyi still remembers that when the Yellow Gate in the palace handed over Liu Wei, who was still in infancy, to him, he suddenly found that his prayers for many years had finally been answered, and God had returned his son to him.

In the six years that he raised Liu Bian, Shi Ziyi poured all the fatherly love he once lacked into Liu Bian. Although there is a huge disparity between Qingzhi and Liu Bian's status, he will never be able to become Liu Bian's father, but this does not prevent him from silently supporting him behind Liu Bian's back like all fathers.

He helped Liu Wei build this secret laboratory, and the disguise was not leaky, and the management was well organized. Behind all this, he has put in great effort and sweat, and the only reward he hopes for is that his children will not be in danger again.

Walking out of the alchemy room and coming to the front yard, Shi Ziyi saw that Liu Wei and his party had already walked in. was about to kneel down to pay homage, but Liu Wei grabbed him first.

"Your Highness."

"Uncle Shi doesn't need to be polite." Liu Wei said with a smile.

"It just rained this day, and it was very cold. Why did Your Highness run away, where am I here? What is important to support the confidant to call out, what if there is something wrong on the road? Shi Ziyi said worriedly.

"There's something to say inside."

Knowing that Shi Ziyi always treated his own safety with a trembling character, Liu Wei didn't care, and took Shi Ziyi's hand and walked in without seeing it.

Walking into the main hall, the two of them sat opposite each other at a low table. Shi Ziyi ordered people to set up the stove, warm the wine, and dismissed the surrounding disciples, leaving only Liu Wei's guards, and then asked again: "Your Highness is here for the construction progress of the thunderstorm?" ”

After listening to Shi Ziyi's words, Liu Wei was first displeased: "Uncle Shi, haven't I said it many times? When there are no outsiders, they still call me to argue! ”

Shi Ziyi said solemnly: "You can call me Uncle Shi, my heart is already very hot." But this etiquette can't be abolished, you are a prince, and it is right to call you His Royal Highness. ”

Liu Wei couldn't resist Shi Ziyi, so he had to follow him. Then he said: "I have come here to see how the thunder is made; Second, the New Year will be in a few months, and I won't be able to get out of the mess in the palace. I have to prepare some things now and bring them to Uncle Shi and the villagers in Jincun, so that they can have a happy New Year! ”

Shi Ziyan bowed down and thanked: "Your Highness has left Jincun for many years, but you still don't forget the hardships of the villagers of Jincun. ”

Liu Wei waved his hand and said with shame: "Uncle Shi is serious. Speaking of which, I'm sorry for the folks in Jincun. Originally, he kept the secret of making glass, and he could have been rich. It's just for me to keep it secret, and let the villagers live a hard life. ”

Shi Ziyi shook his head and said, "If Your Highness blames himself for this, he will make me feel shameless." I told them the truth that he was innocent and guilty, and I told them the secret recipe for making glass when His Highness gave them the secret recipe for making glass. If it weren't for His Highness's protection, I'm afraid that even if they were asked to make a large amount of glass, I am afraid that it would only bring trouble to the village and affect His Highness. Besides, I also understand that the reason why glass is worth a thousand gold is only because it is rare and expensive. If it is produced in large quantities, I am afraid that it will eventually be so cheap that it will not be worth anything. ”

Seeing that Shi Ziyi understood so well, Liu Wei no longer blamed himself, nodded and said, "I brought some bacon and clothes this time, and Uncle Shi helped me distribute them to the villagers in Jincun." Originally, there were a few jars of freshly brewed wine, but I didn't expect to meet a wonderful person on the way, so I gave it to him in one go, and I asked people to send some more when I returned to the palace. ”

Shi Ziyan bowed down to thank him, and Liu Wei asked again: "Now that it is the autumn harvest season, how is this year's harvest in Jincun?" ”

Shi Ziyi hurriedly replied: "It's not bad, since His Royal Highness asked them to plant rice in the south, and taught some farming methods, this year's harvest is very good, and he also sent me some rice a few days ago, and it tastes really fragrant after cooking!" ”

Agriculture is the foundation of a country, and Liu Wei also read some miscellaneous books on this subject when he was working in the library in his previous life. In this era, although it is not possible to make some big changes to the whole country for the time being, Liu Wei is still willing to do it where he can.

Seeing Shi Ziyi's smile, Liu Wei also laughed with relief. After asking a little more about Kanemura, he turned the topic to the production of the Cupola.

Liu knew very little about the production of firearms. In his previous life, he didn't have the opportunity to go to university, and all the knowledge he learned came from the books he read while working in the library, or some materials he looked up on the Internet. Due to the government's control of firearms in the previous life, even some gunpowder, explosives, and firearm manufacturing materials were taken away by river crabs. Therefore, Liu Wei was really helpless about those complicated firearms making, so he had to teach Shi Ziyi some simple gunpowder knowledge and let them study it by themselves.

It is worth mentioning that these Taoist priests were really the earliest chemists in China, and they were not inexperienced in the development of gunpowder, but they were still in the initial stage. After fusing Liu Wei's advanced modern knowledge, one of the four major inventors of China who changed the world, black powder, was finally successfully developed.

After the successful development of black powder, Liu Biao also determined the early research direction of firearms: pistols or inferior firearms temporarily gave up research for technical reasons, and Liu Biao decided to focus on the research of grenades.

Shi Ziyi and his research team did not disappoint Liu Wei, and after unremitting efforts, the grenade was finally developed. Because of its great power, it is named Cupola!

Since the initial thunderbolt was made of iron, it was very difficult to make and was not suitable for mass production, and the effect of the explosion was not very satisfactory -- at most, it only exploded two or three pieces, and it was completely unable to achieve the goal of killing and injuring the enemy in a large area.

Later, bamboo was used as a container for gunpowder, and broken iron or small stones were added, and the effect of the explosion was much better than that of the iron thunder, but it still did not achieve the desired effect.

Liu Wei had been worried about this for a long time, and recently Shi Ziyi came to the news that there had been a big breakthrough in the development of the skyrocket, so he hurried over.

Shi Ziyi knew that it was useless to just talk, so he led Liu Wei to see their research results in person.

The whole pharmacy is divided into two parts: the front yard and the back yard. The front yard is full of alchemy rooms and ordinary living rooms, which Shi Ziyi used to disguise and cover the backyard of the laboratory. The rows of houses in the backyard are the core of the entire medicine house, and even those cronies and disciples under Shi Ziyi can only be entered and exited by a few researchers.

The backyard is connected to a bamboo forest on the mountain, and Shi Ziyi has made great efforts to build a fence to enclose part of the bamboo forest. Liu Wei and his entourage followed Shi Ziyi to the bamboo forest in the backyard, and Shi Ziyi's disciples had already placed the newly developed sky-high thunder on the stone chair under the instructions of the master.

Liu Wei stepped forward and picked up a sky-high thunderbolt, and couldn't help but light up.

The newly made cupola thunder is actually a round tube wrapped in paper, which is not very wide, about the length of his arm, although Liu Wei is young and has small hands, it is not very difficult to hold.

Liu Wei felt that the thunderstorm in front of him was very similar to the firecracker "two kicks" he had lit in his previous life, but the pipe body was densely inlaid with broken iron, and an iron handle was installed underneath.

Although Liu Wei immediately wanted to test the power of a sky-high thunder with his own hands, how could Shi Ziyi, who was worried about his safety, let him do such a thing. A disciple was called to practice in front of Liu Wei.

Seeing the huge power of the sky-rushing thunder, Shi Ziyi asked everyone to take a few steps back, and the disciple ignited the medicine twist and threw the sky-high thunder into the bamboo forest.

There was a loud bang, and the flint burst out. Jiang Qi and the other guards had never seen the power of the sky-rushing thunder, and they couldn't help but scream in fright. Even Liu Wei, who was more mentally prepared, couldn't help but be shocked.

The power of the explosion was so huge that although Liu Wei and the others were already some distance away from the bamboo forest, there were still pieces of iron that bounced to Liu Wei's feet. The group walked into the bamboo forest to check, and found that a one-foot-wide pit had been blown out of the ground, and the surrounding bamboo was full of iron nails, some of which were even more than a person high from the ground.

Jiang Qi laboriously lifted a piece of iron from a piece of bamboo, stared at the piece of iron and muttered: "Once such an artifact comes out, even thousands of troops and horses are invincible!" ”

Liu Wei listened to Jiang Qi's words on the side, shook his head and said: "Although sharp weapons are good, they must also be used by people. If you can't do it, no matter how powerful the weapon is, you will lose a battle. It is important to know that war is a war of the masses, and victory can only be achieved by developing the masses, and only by relying on the ...... of the masses"

Liu Wei stopped abruptly when he talked about this, looking at Jiang Qi around them, their eyes were wide and they were staring, and there was a question mark on their heads. Knowing that he was a little overjoyed, he moved out all the quotations of the chairman. Fortunately, no one dared to ask what he meant, so he coughed dryly and changed his words: "Don't think that you are invincible in the world with a sharp weapon in hand, the most important thing for you to lead the army to fight in the future is to guard against arrogance and rashness, and go back and let Wei Yi give you a good political and ideological lesson!"

Although Jiang Qi and the other guards had never heard of political thought, every day Liu Wei would tell them some theories about the art of war and battle arrays in his previous life, and Jiang Qi and the others gradually had some ideas in their hearts. Today, Liu Wei personally said that he would let them lead the army to fight in the future, confirming the long-term speculation, and everyone was overjoyed. Compared with being a lifelong guard in the deep palace, Jiang Qi and others are more enthusiastic in hoping to go into battle to kill the enemy and serve the country. Wasn't it for this purpose when I learned martial arts to strengthen my body?

Although they were happy in their hearts, they also nodded their heads when they heard Liu Wei's lesson. Shi Ziyi asked people to experiment with a few skyrocketing thunders, which were also extremely powerful and jaw-dropping.

Liu Wei asked about the method of making this sky-high thunder, and Shi Ziyi hurriedly told the truth. It turned out that after the failure of the thunderstorm using bamboo as a material, Liu Wei had advised them to press the iron on the outside instead of pouring it into the bamboo tube with gunpowder. However, the bamboo body is hard, and it is difficult to set iron blocks on the bamboo tube. But when Liu Wei handed over the paper-making method to them for experimentation, a disciple of Shi Ziyi had an idea when he saw the scene of the pulp being baked and dried into cardboard, and thought of wrapping the bamboo tube in a thick pulp, and then embedding the broken iron into the pulp. Then the gunpowder was poured in, the bottom was sealed, the powder twist was inserted, and a powerful thunderbolt was made.

After listening to Shi Ziyi's narration, Liu Wei nodded while secretly sighing in his heart the superb wisdom of the ancient working people. He also put forward some suggestions for improving Shi Ziyi's thunderstorm, looking at the west, knowing that there would be a curfew when it got dark, and he would inevitably encounter trouble when he went back, so he said goodbye to Shi Ziyi and took Jiang Qi and others down the mountain.

The group rushed back, because Liu Wei was young, riding a foal, and not good at riding, so he marched very slowly. Although Jiang Qi and the other guards rode high-headed horses, it was impossible for them to rush back to the city alone past Liu Bian, so they accommodated Liu Bian's horse and walked slowly.

Afraid that he would go back too late and the palace gate would be closed, Jiang Qi asked his subordinates to go to the Canglong Gate in the east of the North Palace to beat the guards first, hoping that the palace gate would be closed later or that they would be able to open the door for them then.

After entering the city, only Jiang Qi and another guard were left to escort Liu Wei to rush back. The sky was getting dark, and there were few pedestrians on the road, so the anxious Liu Wei couldn't help but speed up his horse.

A figure rushed to the horse, and Liu Wei hurriedly reined in the horse, and the front legs of the mount were raised, and a neighing sound. The man fell in front of the horse with an "ahhh
