I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Mo Shi came very quickly, and the smell of blood in the tent had not been completely removed when he came.

Compared with everyone in the tent, Mo Shi and the others who work with mechanics every day should be regarded as real literati.

The moment he stepped into the tent, Mo Shi knew that someone must have died here, and after seeing everyone's dignified expressions, he couldn't help asking cautiously: "Your Highness, you brought all the things you asked for. What are you going to do?"

Liu Tan glanced at him and said, "Find a place far away from here with no people. I want to do something."

This place is so easy to find, there are not many places with high mountains and high mountains, but there are too many places with few people.

Wei Buyi directly took people to clear out a place for them—this one was not people, but birds and animals in the mountains.

In such an environment, a distance of ten or twenty miles is enough to prevent the people of Qilan Kingdom from discovering any clues.

When Liu Tan brought Mo and they came over, he solemnly said to them: "This kind of thing is very lethal, and it may violate the principles of your Mohism. I must make this clear in advance. If anyone can't accept it, you can withdraw first. I will send someone to Escort you back."

Mo Shi and the others were taken aback for a moment, how lethal is it?

They really couldn't imagine what kind of lethality saltpeter, sulfur, and charcoal could have. However, His Royal Highness the King of the North never told lies, so he said that the lethality must be great.

Mo Shi turned his head and took a look and said, "Anyone who wants to quit, just quit."

Something with great lethality means that it will definitely become the core secret of the northern border country, that is to say, they have been tied to the northern border country for their entire lives, and it may be extremely difficult to return to Chang'an.

But Mo Shi didn't care about that much. He used to think that the Mo family needed to be promoted to a higher level. The root cause was that the status of the Mo family was too low. Even an official had to salute when he met an old farmer with a title in the field.

There are too few resources available for such a position.

Mechanism consumes resources so much.

But now with the King of the North, he feels very at ease. He doesn't have to think about those twists and turns, and he doesn't have to fight with anyone. He just needs to do his job well, and he doesn't even have to worry about materials and money.

The gods don't change these days. In comparison, go back to Chang'an?Why do you want to go back to Chang'an?

Going back to Chang'an would be a little more aggrieved, it would be better to stay in the northern border country.

Mo Shi made his decision almost instantly.

The younger brothers and sisters behind him were a little dazed at first, but soon they all wanted to understand the meaning of His Highness the King of the Northern Realm's words, and almost instantly, everyone decided to stay.

There is the influence of Mo Shi's attitude, and it is more because they are the best in the Mo family, but they are not so outstanding.

Now that even the most outstanding Mo Shi has given up, what can they do when they go back?

It's better to stay in the northern border country!

After watching them make a decision, Liu Tan smiled and said, "Okay, don't worry, I won't treat my people badly."

After he finished speaking, he said: "This thing is actually not difficult. I have the formula in mind, but you still need to master it as a whole. Also, you must be careful during the preparation process, and you must not let the fire source get close, otherwise your life will be lost." , remember to remember."

When Mo Shi and the others saw him speak so seriously, they couldn't help swallowing for a moment and felt very nervous, but they still nodded.

Liu Tan said: "Now make a small portion first. The formula is one sulfur, two nitrates, and three charcoals. According to this ratio, the total weight should not exceed three taels."

Mo Shi was a little surprised, but he quickly compared the things.

Among them, the treatment of saltpeter is a bit more troublesome, because it needs to be made into powder, and then charcoal and sulfur. After mixing everything, Liu Tan asked them to wrap these things in cloth, and then got some cotton rope as a lead wire.

Liu Tan asked everyone to stand far away, and sent the fastest guard to light the fuse.

After igniting the fuse, the guard ran back in one breath, and the moment he stood in front of Liu Tan to protect him, suddenly there was a sound like thunder.

The place where the cloth bag was originally buried was instantly splashed with mud, and a burst of gunpowder smoke drifted past. When everyone looked closely, they found that there was only a hole left in that place.

Liu Tan raised his foot and was about to go that way, Wei Fu and Wei Buyi beside him held him vigilantly and said, "Your Highness, be careful!"

Liu Tan shook his arms and said, "Let it go, let me go, can I not know what I made myself?"

Wei Wei and Wei Buyi thought it was an accident at first, but now they let go of Liu Tan's words hesitantly.

The group of people, except Liu Tan, walked there cautiously.

Liu Tan went there and looked down, and found that the things he had just configured were still a little bit left, and the power was not very great.

He turned his head to look at Mo Shi and said, "Do you understand?"

However, Mo Shi was suspicious of life at this time. After hearing Liu talking about this question, he hesitated and shook his head: "Your Highness, this is... what is this?"

Liu Tan took a deep breath, smelled the faint smell of sulfur and said, "This is black powder."

Black gunpowder, everyone repeated these three words in their hearts, as if they could faintly feel something from the name.

Mo Shi coughed lightly and asked, "Your Highness, what is the use of this thing?"

Liu Tan pointed to his feet and asked, "Didn't you see it? It can explode after being ignited. Did you know that wine cellars can explode?"

Everyone nodded immediately. Although there were not many wine cellar explosions, everyone knew about it.

Liu Tan hummed and said, "Strictly speaking, the effect is about the same, but this is much better than wine."

Mo Shi couldn't help asking: "But... His Highness said that the lethality...is very big?"

Liu Tan glanced at him, turned around and said, "Catch some rabbits or something else."

In the end, the guards caught all kinds of strange things, but the pheasants and rabbits were the most.

Liu Tan had someone tie up the pheasant and the rabbit and throw them on the ground buried with black powder, then raised his chin and said, "Light it on fire."

This time, because the weight is a bit more, the sound of the explosion is naturally louder.

After the sound passed, everyone rubbed their ears at the same time, but after rubbing their ears, they were startled by the scene in front of them - fragments of fur and pieces of meat were scattered everywhere on the ground in front of them, and blood was scattered all over the place. Suddenly, a large part of those meat pieces turned into a charred black color.

Because it still has fur, it is easy to tell that these things come from the pheasant and rabbit just now.

Liu Tan watched them stunned and said meaningfully: "Think about it, if there is enough weight, what should people... be?"

Wei Wei, Wei Buyi and Li Ling were the first to react. They imagined the scene and gasped suddenly.

If the weight is enough, how can there be life in this one?

Wei Kangchi questioned: "Your Highness, are you... going to use this thing to deal with Qilan Kingdom?"

Liu Tan said plainly: "I don't have time to talk nonsense with them. Father doesn't know what's going on on the island. Since they are looking for death, don't blame me."

After he finished speaking, he turned his head to Mo and said: "Go ahead, get a rack catapult, it doesn't need to be too big, as long as it can throw black powder into it, and then study the weight, remember that you must not touch the fire when you make it , by the way, keep the black powder dry, otherwise you will either be blown up, or the black powder will not explode because it is too wet."

Mo Shi and the others came back to their senses, glanced at the flesh and blood on the ground, smiled and said, "So that's what your highness said about the lethality, and your highness looks down on us too much. We just don’t advocate fighting, but we can fight when necessary, don’t worry, Your Highness, we will finish it soon.”

Liu Tan nodded, and Mo Shi asked again, "It's just, where are we going to put the black powder after it's mixed?"

Even a catapult can't throw dust. It would be too extravagant to use cloth, not to mention that the cloth bag is not that strong.

Liu Tan turned around and said, "Put it in a wine barrel."

They brought a lot of wine with them because a doctor said it could dispel dampness.

He knew how to dispel the cold with wine. As for dispelling dampness, different people have different opinions, but Liu Tan did not object, and now it has come in handy.

The most difficult thing about black powder is to study the ratio. Now that this problem has been directly solved by Liu Tan, the next things have become much easier.

After the envoy was killed, King Qilan seemed to be very angry and sent people to attack. However, Qilan Kingdom didn't have bows and arrows, so they used blowing arrows.

The range of this thing is not far, and its power is not too great. The only thing to worry about is the poison smeared on it.

Liu Tan asked people not to go into the dense forest and stay in the camp as much as possible, and the outermost part of the camp was full of tents. If those Qilan people wanted to sneak attack, they had to come out of the forest. Blowing arrows can't do anything to the army of the big man.

However, it can only be like this. Those Qilan people are like mountain monkeys. They will scatter all over the mountains and plains if they miss a blow. They are not familiar with the terrain, and they are not as flexible as these people in the mountains and forests. Naturally, they cannot catch up. of.

Mrs. and Mrs. Wei are better. Wei Buyi has never experienced such a useless attitude since he started leading troops with Liu Tan. He couldn't help cursing for a while: "Aren't they all reincarnated monkeys? They are all short and small. , looks like a monkey."

Liu Tan glanced at him and said, "I'll ask the doctor to prescribe some anti-anger medicine for you later, and see what the Qilan people have done to you?"

Wei Buyi couldn't help but said: "Your Highness, this is a bit aggrieved."

Liu Tan took a sip of honey water and said, "How can people go smoothly? What's more, what's the rush? We're now..."

Before he could finish his sentence, he heard Mo Shi outside happily shouting: "Your Highness, everything is ready!"

Liu Tan took a deep breath: "Alright, it's time for Qilan Kingdom to disappear."
