I'm a useless prince, so what if I know a little bit of chemistry?

Zhang Guangzhi smiled slightly, indicating that he didn't care.

"Everything is subject to the Lord's arrangements."

Lin Fan patted Zhang Guangzhi on the shoulder and said, "Don't worry, I will definitely surprise you."

After Lin Fan waited for Chu Hu to move the things in, he walked in himself.

Lin Fan planned to develop black gunpowder. After all, he would have to clash with hundreds of thousands of troops. Lin Fan did not have the confidence to do so. He was not Xiang Yu who could move mountains. Naturally, he could not take the head of a general from among thousands of soldiers.

Therefore, Lin Fan planned to develop black gunpowder. In this era of cold weapons, the emergence of black gunpowder would certainly be a dimensionality reduction attack.

Moreover, Lin Fan is a versatile scientist and is naturally very familiar with the composition of gunpowder.

The main ingredients of black powder are sulfur, saltpeter and charcoal. In Lin Fan's era, everyone knew that the ingredients are saltpeter, sulfur and charcoal.

The ratio of these three is the key to the power of black powder.

Of course, this is not a problem for Lin Fan. The best ratios of saltpeter, sulfur and charcoal are 74.84%, 11.84% and 11.32% respectively. At this moment, the power of black gunpowder is also the greatest.

However, the materials nowadays are not the purest, and Lin Fan has no choice but to make the closest ingredients.

Lin Fan first calculated the required ingredients on paper, and then he took the scale and started weighing.

Since all three items were already in powder form, it was particularly convenient for Lin Fan to weigh them, and he quickly found the appropriate weight.

Afterwards, Lin Fan began to put the weighed gunpowder into a jar.

The next step is to make the fuse. This step is also extremely important. If there is a slight deviation, it will either burn too quickly and blow up its own people, or it will not burn at all, making the entire bomb useless.

Lin Fan planned to weave a rope out of paper and wrap a layer of gunpowder inside.

Lin Fan did what he said and soon made a piece of fuse about 50 centimeters long.

"I don't know if it will work or not. Success or failure depends on this one move."

Lin Fan took out a tinderbox, and when he lit it, he used the burning end to ignite the other end of the fuse.

Under the high temperature, only the paper on top burned, but the black powder inside did not burn.

"Did it fail?" Lin Fan was a little confused. After muttering to himself, he picked up the prepared black gunpowder and looked at it.

But just by looking at it, Lin Fan couldn't tell anything. He twisted it with his fingers, then put it under his nose and smelled it, and there seemed to be nothing wrong.

With a breakthrough and a "puff", the fuse that Lin Fan had originally determined to have failed suddenly started to burn, and its burning speed was not slow.

"It's done." Lin Fan said in surprise.

Just by thinking about it, I realized that the reason why the fuse was not lit was probably because of my technique.

With the fuse, we can make explosives.

The production method that Lin Fan planned was very simple, which was to use a wine jar as a container and stones as shrapnel.

Lin Fan poured the black gunpowder into a clean wine jar. When it was halfway filled, he compacted the black gunpowder and then covered it with a layer of sand. He then put a lot of stones on the sand and then sealed it.

At that time, when all this was going on, Lin Fan placed a fuse in the pile of gunpowder.

outside the house.

"Master Zhang, what do you think the Marquis is planning to do?" Chu Hu asked, feeling a little bored.

"I am not the Marquis, how can I know? Besides, when has the Marquis ever disappointed anyone?" Zhang Guangzhi smiled, as if he was not worried.

Chu Hu scratched his head and said, "I am just anxious. Do you think the Marquis will really make an elixir? But I have never heard that the Marquis can make an elixir before."

Zhang Guangzhi was somewhat confused about this, but he was very clear about one thing, that is, Lin Fan would definitely not really make pills, at most he would just tinker with something they didn't know about.

"I don't know, but it's definitely not alchemy. That thing is useless after eating. It's just illusory." Zhang Guangzhi said lightly.

"Alas, it's been such a long time, and I still don't know what the Marquis is tinkering with." Chu Hu said boredly.

Squeak!

As soon as he finished speaking, the door was opened.

Lin Fan came out holding a wine jar, with a string covering the jar.

"My lord, what is this?" Zhang Guangzhi asked.

Lin Fan gently patted the wine jar in his hand and said, "The ultimate killer, it depends on him to break the situation."

"A powerful weapon? Isn't this just a wine jar?" Chu Hu asked casually, expressing his doubts.

"That's right. Whether or not my uncle can be rescued depends on him." Lin Fan said.

"My lord, are you planning to get them drunk? Let me tell you, with jars of this size, I can drink three jars by myself. If you want to get hundreds of thousands of people drunk, how much wine will be needed?" Chu Hu said.

Lin Fan kicked Chu Hu lightly and said, "Stop talking nonsense. Let's find a wide flat area outside the city. Oh, and find a few people who are good at archery. We need rocket arrows."

"Yes."

Chu Hu didn't ask any more questions, but started to prepare immediately.

"My lord, I am looking forward to it more and more." said Zhang Guangzhi.

“As long as we succeed, we can even defeat an army of hundreds of thousands.” Lin Fan said, looking into the distance.

……

outside the city.

By the time Lin Fan and Zhang Guangzhi arrived, Chu Hu had already sent people to dig a pit large enough to accommodate one person.

"My lord, how is it? Is it big enough? Do you need me to dig deeper?" Chu Hu asked.

"No need, let the brothers step back." Lin Fan said to Xiang Long.

There were about fifty people who followed Lin Fan out of the city.

These people were not brought by Lin Fan to protect himself, but to prevent information from leaking.

"Everyone retreat a hundred steps!" Xiang Long shouted.

"Yes!"

More than fifty people retreated in unison. Lin Fan handed the jar to Xiang Long and said, "Put this at the bottom of the pit."

After Xiang Long took the jar, he jumped into the pit. After putting the jar away, Xiang Long jumped up again swiftly.

This time the fuse is very long, so there is no need to worry about it burning too quickly.

"That's about it, let's retreat too." Lin Fan said.

"My lord, how can this wine jar be used to eat people?" Chu Hu asked.

"You'll know in a minute."

After retreating a hundred steps away, Lin Fan asked, "Who shoots the best arrows?"

"My lord, when it comes to archery, I am the best." Chu Hu said confidently.

Seeing that Lin Fan was a little confused, Xiang Long explained: "Yes, Chu Hu's archery skills are indeed good."

"Okay, I didn't notice that." Lin Fan was a little surprised.

"That's right, I am a real person who never shows my true face." Chu Hu said proudly.

Lin Fan pointed at a section of the fuse and said to Chu Hu:

"Stop talking nonsense. See that line? Shoot it with a rocket. It's a hundred steps away. Can you do it, Fatty?"

Chu Hu was inspired by Lin Fan, so he took out his bow, lit the arrow, and drew the bow and arrow, saying: "My Lord, watch me shoot an arrow through a hundred steps!"
