    ??

    Zhao Chen took Li Shimin and walked inside. There were servants of the Zhao family standing guard at the door.

    Since Sun Li brought the 200 trained servants of the Zhao family to Yamato, Qin Qiong once again recruited 300 farmers to train as full-time security guards of the Zhao family.

    Now the Zhao Mansion is very big, but the farmers in the Zhao Mansion all abide by the various rules set by Zhao Chen: for example, no littering is allowed, and neighbors must be harmonious and help each other.

    The farmers in the Zhao Manor performed very well. After all, this era was the Tang Dynasty, and it was not like the modern times that followed. People had good relationships with each other. The Tang Dynasty also had the style of Ren Xia, which was prevalent. In other words,  The people are relatively simple, so it is easier to manage.

    When he entered the industrial park, Zhao Chen went directly to ask someone to call Lu Zhengzhong.

    Soon, a craftsman trotted over and saluted immediately when he saw Zhao Chen.

    "Mr. Zhao."

    Zhao Chen smiled and said, "How is the research and development going?"

    The craftsman scratched his head: "According to Mr. Zhao's instructions, it is still somewhat difficult. We are still exploring."

    "Nothing dangerous happened, right?"

    Lu Zhengzhong hesitated for a moment: "Yes, I was experimenting with the materials Mr. Zhao mentioned before and combining them. At that time, a craftsman didn't pay much attention and was directly injured in the arm."

    Zhao Chen¡¯s expression condensed: ¡°Have you sent him to Datang Central Hospital?¡±

    "Don't worry, Mr. Zhao, we sent him to the Central Hospital as soon as possible. He is now recovering in the hospital."

    Zhao Chen then nodded: "This matter is very dangerous and is no joke, so you must be careful every day."

    "Okay Mr. Zhao, let's be careful."

    Hearing the conversation between Zhao Chen and the craftsman, Li Shimin also had doubts in his eyes, what is so dangerous?

    "Lead the way, I want to go in and take a look."

    "It's Mr. Zhao."

    Lu Zhengzhong walked forward, and Zhao Chen and Li Shimin entered the craftsman's workshop directly in front.

    As soon as I entered the craftsman's workshop, I found someone taking notes and a bunch of people using materials, as if they were synthesizing something.

    "Mr. Zhao, what kind of craftsmen are these people?"

    "Oh, they are not craftsmen. I called them over because they planned to make fireworks."

    "fireworks?"

    Li Shimin looked puzzled.

    "The evolved version of firecrackers."

    A picture suddenly appeared in Li Shimin's mind: countless bamboos were crackling.

    He laughed dumbly: "Mr. Zhao, then this craftsman is of no use, how can it be dangerous?"

    Zhao Chen knew that Li Shimin had misunderstood: "Your Majesty, the firecrackers you understand are not the kind of firecrackers I mentioned. You will know later."

    In the Tang Dynasty, although there were firecrackers, the firecrackers at this time were not firecrackers in the later sense, but firecrackers in the literal sense, which were crackling bamboos.

    In the early days, firecrackers were actually bamboo explosions. In the past, people would often light a fire in the backyard during the Chinese New Year, and then throw some old and broken things into it, including bamboo, and bamboo was used in such  Under certain circumstances, there will always be a "pop, pop, pop" sound, so this special festive sound attracts people. Every New Year, they will throw a pile of bamboo into the fire, which is also called firecrackers.

    In the earliest days, the original purpose of people setting off firecrackers was to burn all the old and past things, that is, to part ways with each other. Only later did they get into the habit of throwing bamboos to celebrate.

    This is called firecrackers. As for fireworks, gunpowder in the Tang Dynasty was not popular at all. Now gunpowder is only possible in the furnaces of Taoist priests for alchemy. Gunpowder really became popular in the Song Dynasty, and fireworks only began to appear in the Song Dynasty.  , in the Tang Dynasty, people often set off firecrackers.

    That¡¯s why Li Shimin laughed when Zhao Chen mentioned firecrackers just now.

    And Zhao Chen asked again: "Where are the Taoist priests that Master Yuxu invited?"

    "Here, here, Mr. Zhao, we are here."

    Li Shimin was stunned again, only to see several Taoist priests in Taoist robes trotting over to the craftsman's workshop.

    "Ah this"

    Why are there still Taoist priests?

    Zhao Chen asked again: "What do you think of the things I asked you to make?"

    "Mr. Zhao, this is really difficult, and we don't quite remember it."

    "Why don't you remember? This prince-in-law is just"??You will use the elixir for blasting the furnace again, and you won¡¯t remember it?  "

    "This, we are trying."

    A Taoist priest apologized and said, "Mr. Zhao, when will you tell us again about Chen Beixuan's path to immortality?"

    "Yes, yes, yes, last time you only talked about him cultivating to the foundation. What is the next step, Nascent Soul? Is there anything else after Nascent Soul?"

    The two Taoist priests stared at Zhao Chen eagerly.

    Zhao Chen felt helpless for a while: "Okay, let me tell you a short paragraph first. Last time I talked about Chen Beixuan being chased by people from the Xie Yun Sect. As for Chen Beixuan, he had a sword that had been refined for a long time. Seeing those people chasing him closely,  Chen Bei

    With a sudden sound, the sword gleamed with red light and went straight towards the two Xie Yun Sect disciples who were chasing them. The red light flashed and the sword passed through the necks of the two men at an extremely fast speed.  As the saying goes: Eight hundred autumns have passed since I attained Taoism, and no one has been killed with flying swords.  The Jade Emperor's heavenly talisman has not yet arrived, and his goods, black and gold, are floating around the world.  Well, that¡¯s it for today.  "

    The two Taoist priests listened intoxicated. When they heard that Zhao Chen only talked for such a short paragraph and stopped talking, they suddenly became anxious: "Mr. Zhao, keep talking."

    "What are you talking about? I didn't see that I'm busy now. Next time."

    Zhao Chen was also quite helpless. Inventing gunpowder was a bit difficult. Although he listed the formula of black gunpowder, it was still very difficult because no one had experience. After thinking about it, the most experienced candidate was obviously  ,Taoist priest!

    That's right, he directly sent people to various Taoist temples to get to know the Taoist priests who were obsessed with the method of alchemy, and then invited these Taoist priests to make gunpowder. However, these two Taoist priests were obsessed with cultivating immortals. As a last resort, Zhao Chen could only  I can tell them novels about cultivating immortals.

    Coupled with the guidance and assistance of professional craftsmen, the difficulty is actually not that high.

    After all, the formula of gunpowder is very simple. Potassium nitrate 75¨G, sulfur 10¨G, and charcoal 15¨G. This is the main formula. According to this formula, gunpowder can be made.

    The current preliminary plan is to produce black powder.

    By then, it will be time for the military strength of the Tang Dynasty to transcend the times!

    But Zhao Chen's purpose is far from this, because there are two kinds of gunpowder in the whole gunpowder, one is the black gunpowder invented by China, and the other is the yellow gunpowder invented by Nobel. This kind of gunpowder is called dynamite.  Trinitrotoluene is a compound.

    Yellow gunpowder is more stable than black gunpowder; friction, shipping, and even open flames cannot detonate it, whereas black gunpowder is different and can be ignited by violent impact or sparks.

    Therefore, Zhao Chen¡¯s goal is to produce yellow explosives, but it is estimated that there is still some way to go. To invent yellow explosives, nitroglycerin and diatomaceous earth are needed as absorbents.

    Pushing the two Taoist priests aside, Zhao Chen asked: "After working for so long, you should have a finished product, right? I even gave you Sun Simiao's method."

    "Yes, yes, Mr. Zhao, we have developed some of the fireworks you want, but they are not very stable."

    "Is it really there? Let's go outside and demonstrate it."

    Li Shimin followed Zhao Chen, and he became more curious about these so-called fireworks.  (Remember the website address: www.hlnovel.com
