If it was another way, Lin Mu might not be able to think of it for a while, but the material of this "dynamite", gunpowder, was originally invented by an alchemist in the teacher's world.

In fact, on the Lingwu Continent, there were already alchemists who had already made gunpowder.

However, the Lingwu Continent respects martial arts, and people don't look down on the power of gunpowder at all, and they have never thought of going to the past to study and transform in depth.

The world of the teacher is different, most human beings are mortals, respected by science and technology, and are accustomed to using and developing external forces, so the use of gunpowder has been developed to the extreme by that world.

The gunpowder itself is not very powerful, and can only be used as a pyrotechnic fire.

However, if the gunpowder formula is properly modified and compressed into a container with a limited volume, the power of the explosion will be beyond imagination.

The last time the Qiao family came to Xichuan City, it was really unexpected by him, and he was caught off guard, and he didn't have time to prepare.

Otherwise, he'd probably have planted explosives then.

Immediately, Lin Mu returned to the Wind Chime Medicine Pavilion.

"Little bowl, help me prepare enough iron sheets and send them to the alchemy room tomorrow."

After handing over the preparation of the iron sheet to Lin Xiaowan, Lin Mu went directly into the alchemy room.

Inside the Dan room, there was no shortage of sulfur, saltpeter and charcoal, and there was even ready-made gunpowder.

However, the ratio of gunpowder, sulfur and saltpeter is mostly one to one, and the power is not strong enough, and the forest and animal husbandry need to be reconfigured.

Lin Mu also didn't know how lethal gunpowder was to the martial artists, so he could only refine it with all his might, and how much he could refine.

Two days later, in the alchemy room, Lin Mu wiped his sweat and lay down on the chair next to him tiredly.

Although his body was tired, his spirit was good.

In front of him, a black powder had piled up into a hill.

These black powders, which are exactly the ratio of gunpowder, sulfur and saltpeter that he made, were one to three.

In the teacher's memory, such a ratio is close to the most recent proportion.

After only lying down for a while, Lin Mu quickly stood up again.

In two days, he had to hurry up and make the gunpowder into explosives.

Opening the door of the alchemy room, Lin Mu's eyes lit up, and the outside was already full of iron sheets of various colors.

After quickly selecting some of the best colors, Lin Mu returned to the alchemy room again.

The gunpowder was wrapped in iron sheets, then tightly compressed and sealed.

Ten oval-shaped, two-meter-long bombs were soon neatly arranged in front of Lin Mu.

"Young Master, what are these iron eggs for?"

When Lin Mu opened the door before, Lin Xiaowan noticed it, and stood at the door at the moment, looking curiously at the ten "big iron eggs".

Lin Mu smiled heartily: "This thing is called a bomb, and the specific effect will be known after tomorrow." ”

With that, he waved his hand and put all ten bombs into the space ring.

It was obviously inappropriate to arrange bombs during the day, Lin Mu thought about it, and planned to look for Tang Xixi.

"Xiaowan, do you know where Tang Xixi is?"

After coming back this time, he hadn't looked for Tang Xixi yet, so he could only ask Lin Xiaowan.

Tang Xixi is considered to be the person he trusts more, and Lin Xiaowan can serve as the shopkeeper of the Wind Chime Medicine Pavilion, which was introduced by Tang Xixi.

Moreover, Tang Xixi has a talent for business, which is related to his other plan.

"She's in the West Water Bay Annex."

Lin Xiaowan and Tang Xixi are usually in contact, but they are quite clear about this.

Xishuiwan, located in the south of Xichuan City, is a famous luxury courtyard area in the city.

Tang Xixi's courtyard, covering an area of more than 500 square meters, is very simple to furnish.

For Tang Xixi, Lin Mu didn't need to hide his identity, and when he arrived outside the courtyard, he directly restored his original appearance.

When he entered the main pavilion of the courtyard, Tang Xixi was standing on a ladder next to a bookshelf, tiptoeing, as if he wanted to pick up some book.

"Huh? Brother Demon King? ”

Her eyes were very pointed, and she found out as soon as Lin Mu came in.

Lin Mu walked in, and when he heard this, he wondered, "What Demon King Brother?" ”

Tang Xixi's eyes rolled: "I am a genius, known as the little witch, you and I are both shareholders of the Wind Chime Medicine Pavilion, of course you have to take a majestic name, I think the demon king brother is the most suitable." ”

"Really?"

Lin Mu looked at her with some doubts.

"Of course."

Tang Xixi grinned, and said meaningfully in an instant, "Brother Demon King, I heard before that Demon Kings are multifaceted and have many different incarnations, do you think it's interesting?" ”

Lin Mu suddenly felt a cold sweat, and hurriedly looked at himself to make sure that he had indeed changed his clothes, and then he breathed a sigh of relief.

Rao was like this, he didn't dare to accompany the little witch to continue talking about this topic, and said, "What are you doing on it?" ”

"Get the book."

Tang Xixi's little hand continued to grope on it.

"I'll get it for you?"

Lin Mu asked.

"No, I've found it."

Tang Xixi wiped the beads of sweat on his forehead and exhaled a long breath, "I'm tired, it's really heavy." ”

"How much can a book weigh."

Lin Mu sat down on the chair next to him, and when he saw that tea was brewed on the table, he made himself a cup of tea to drink.

"It's not heavy, but my chest is heavy."

Tang Xixi looked down at his chest and sighed.

"Poof."

The tea that Lin Mu had just drunk squirted out on the spot.

"Giggles."

Tang Xixi happily jumped off the ladder, took the book, and walked towards Lin Mu.

It's just that between her and Lin Mu, there are two fixed ladders, and there is only a small aisle in the middle.

?? t5瞺?2(]{x?釹?y?9?;??? m4 Just when Lin Mu thought that Tang Xixi was going to come in a circle, she didn't expect her to turn sideways and want to get straight through the two ladder aisles.

"You're still really lazy, and you don't want to go around in circles."

Lin Mu shook his head.

"I used to walk from here a lot, so it's a hassle."

Tang Xixi said disapprerovingly.

Before she finished speaking, her brows furrowed, how did she feel so crowded, could it be that the aisle of this bookshelf has become smaller?

It doesn't make sense, this bookshelf is fixed and can't be moved.

Thinking about it, Tang Xixi worked harder and harder, and finally got half of his body into the bookshelf aisle.

But when she tried to get out, sweat flowed from her face.

Her chest hurt so much, Tang Xixi was anxious for a while, and she found that her chest happened to be stuck by the ladder.

"Oops, it hurts."

Tang Xixi tried hard to get out, but his body was still stuck, and his chest was painful.

"What's wrong?"

Lin Mu looked at her puzzled.

"I can't get out."

Tang Xixi said with a bitter face.

"Then you better go back and take a detour."

Lin Mu didn't think much about it and continued to drink tea.

"That's all there is to it."

Tang Xixi sighed helplessly, moved his body, and wanted to go back.

But soon, she knew that the idea was too naïve.

She squeezed in very hard, and it was good that people were easy to exert themselves when they were outside, but now they are stuck in the middle, and they can't use their strength, and they can't get out if they want to.

"Brother Demon King, help."

Tang Xi was anxious, and hurriedly waved his hand to Lin Mu.

She felt that her chest was stuck so much that it hurt so much, and she was really afraid that it would burst.

"Don't move yet, I'll take a look."

Lin Mu also sensed that something was wrong, and hurriedly took a few steps closer.
