"Master, get up. Erin opened the curtains, and the sunlight fell on Wang's pen, and Erin walked to the bed, ready to help Wang's pen get up.

Wang Mubi rubbed his eyes, blocked Irene's hand, got up, patted his legs, and signaled that his legs were almost healed.

"Irene, what time is it? ”

"It's nine o'clock, I saw that the master slept soundly before, so I didn't call the master. Erin handed over her clothes, and continued,

"Ella, they're already on their way, master. ”

"Hmm. "Actually, Wang Mubi knew that when Ella left, he ran to Wang Mubi's room, and then Wang Mubi slept a little back, so he slept a little longer today.

The two went downstairs, only to see Milley sitting on a table eating.

"Milley, you're back, and what do I want?" Wang Mubi was a little surprised when he saw Mi Lai, it seemed that they were moving very fast with a lot of money.

"Big brother, I'm back first, they're still behind, I'm going to take the car to help after breakfast, and the car overturned two. Millai saw Wang's pen and explained the situation.

"Is that so...... When will it arrive?" Wang Mubi was not surprised, when he saw them change the four-wheeled car to a three-wheeled vehicle, he actually had a hunch, although the three-wheeled vehicle was more flexible than the four-wheeled wheel, it was easier to overturn, but he didn't expect it to be delayed so much before.

"In the afternoon, I'm leaving my eldest brother. Millay finished his meal and hurried outside.

"Well, okay, you guys hurry up. Wang Mubi watched Milley leave, turned to Erin and said,

"Let's finish eating quickly, and then go find Qian Duoduo, it looks like we can get busy today." ”

......

After Wang Mubi finished eating, he took Erin out of the door, Qian Duoduo was already waiting in the center of the town, and when he saw Wang Mubi, he greeted him,

"You're here, you've been here, Milai has been. ”

"Well, he said that it will be in the afternoon, are the things I asked you to prepare ready?" Wang Mubi looked around Qian Duoduo, and there seemed to be nothing, and asked.

"Well, it's on the west side of town, there's no one over there, it's more hidden, let's talk as we go. After Qian Duoduo finished speaking, he led Wang Mubi to the west of the town.

"The charcoal powder you mentioned, we have prepared, and then the bones, but this thing, we don't prepare much, after all, the town still mainly eats bread, and the bones of those beasts have not been deliberately collected, but it's a pity that Milai and their car overturned, otherwise it is estimated that they can be prepared in the morning. ”

"Don't worry, four-wheeled vehicles are more stable than tricycles, don't use tricycles for long-distance transportation, bones will go to the dark fortress by then, it should be very easy to get, toner will only be useful in the afternoon, by the way, are there a few craftsmen from Ore Town?"

"Yes, but the lord of Ore Town is not easy to grind, and we don't want to waste time, so in the end, there are three carts of sulfur and eight carts of saltpeter, three masters and six apprentices, plus Li Xiaoer from our town, I don't know if it's enough. Qian Duoduo said in detail.

"Why is there so little brimstone?" Wang raised his eyebrows.

"Sulfur can be used to make matches, and it is still very popular among the nobility, so they refuse to give more. ”

"Okay, did Li Xiaoer go to the Dark Fortress?" Wang Mubi didn't care, and said another thing.

"Well, I've been there, I guess there's the kind of stone you mentioned, after all, we have a lot of them here. ”

"Well, when those craftsmen arrive, let them go to the Dark Fortress to follow Li Xiaoer to build a kiln. Wang Mubi nodded, and at this time, several people followed Qian Duoduo to an open courtyard, but saw that Lin Sensen had already arrived.

"Brush, Irene, you're here. Lin Sensen saw Wang Mubi and said hello.

"Well, Dr. Lin, bring the things. ”

"It's all here, but I don't have much. Lin Sensen opened a package, took two small jars, and said,

"I've already ground them into powder as requested by the pen, but what do you want to do?"

"Wait and so on, but you have to remember that this matter must be made a top secret, this time because the time is a little urgent, so there is no cover-up, and next time it can't be like this. ”

Wang Mubi solemnly opened the jar brought by Lin Sensen, and poured out some powder respectively, which was sulfur and saltpeter.

"Don't worry, if you say so, we'll treat it as top secret. Qian Duoduo nodded.

Wang picked up the spoon, mixed the toner sulfur saltpeter evenly in proportion, and then ...... Pull up Erin and run into the distance and shout,

"Okay, the old money is handed over to you, take the fire, remember to stay away, I am not responsible for rushing to myself. ”

"......" Qian Duoduo was speechless.

"......" Lin Sensen was also silent, took a few steps back, well done, old gentleman.

"Pen ...... You're ...... I'm not going to die. Qian Duoduo realized the danger and said worriedly.

"It's okay, I'm just exaggerating, this weight, as long as you don't stand too close, there will be no accident at all, you can rest assured." Although Wang Mubi said, he didn't mean to get close at all.

"......" Qian Duoduo hesitated, sighed, lit the torch, and handed it over.

Seeing that the mixture burned violently in an instant, sparks splashed everywhere, Qian Duoduo was startled, dropped the torch, and hurriedly ran to Wang Mubi's side.

"Okay, okay, such a small amount, nothing, you see, it's all out. Wang pointed to the mixture and said, Qian Duoduo listened, and when he looked back, he saw that the mixture had been burned, and only a black thing remained.

"Whew... Call... What is this...... Qian Duoduo was shocked and asked Wang Mubi.

“...... Gunpowder, it's not a good thing, but it should be good to use against those monsters. In fact, the invention of gunpowder is more like a disaster for human beings.

"This ...... What would happen if there was a lot of this? Lin Sensen immediately grasped the point.

"Whew, it will explode, this thing burns too fast, if the amount is too large, because the gas released in a short period of time is too large, if it accumulates too much, it will cause the gas to expand and explode in a small area. But you don't usually do that, you think, you use a stone or even an iron to fill this thing, and then it will be ignited. Wang explained as simply as possible.

"Well, do you mean this thing can even blow up iron?"

"This thing, if the amount is enough, it is not a problem to open the mountain and crack the rock, so the confidential work will be handed over to you in the future, find a trustworthy person to do this, I will write down several commonly used usages and safety matters for you, but this amount is still not enough, buy it later, remember to mix it with other things." Wang Mubi said, walking towards another pile of bones.
