High-rise buildings appeared around him one after another, and the place where he stood became a concrete street full of cars parked on both sides. Pen Fun Pavilion wWw. ｂiquge。 info He clearly saw a lamppost on the street, and there were small advertisements pasted on it.

"It's funny, it's a novelty in this world. The voice was very unexpected and pleasantly surprised. Chen Xiao looked around blankly, this familiar picture, the familiar scene, isn't it the street of the community where he lives?

What's going on? Who is that voice? Chen Xiao suppressed the panic in his heart and said, "Who are you? Sneaky and afraid to show up. ”

He couldn't help but wonder in his heart, could it be that the golden finger, the super system, or the old man who was given to me only showed up now? I bought a watch last year, and I said that the traverser has benefits, but he has not shown up before, it turns out that it is the network delay.

Chen Xiao was instantly excited.

The voice seemed to be happy, and he quacked, "Who am I? I don't even know who I am. Perhaps, you can call me a demon. ”

The voice of the self-proclaimed demon came from far and near, and when Chen Xiaoding looked at it, he saw a thin man dressed exactly like him appear in front of him.

The man was skinny, with purple hair and bloodshot eyes. It looks like an African refugee who has been hungry for many days.

"Demon?" Chen Xiao frowned slightly, could it be that he opened it in the wrong way? This demon looks more shabby than him, not like Goldfinger and Old Grandpa.

The purple-haired man grinned like a shark, "That's right, it's a demon." The demon that once destroyed the world, do you know why you are here?"

"That's because you're getting something you shouldn't have. So you need to pay for it. I'm imprisoned here forever in my place. ”

With that, the purple-haired man raised his right hand. His right fingernail was long, untrimmed in years, and looked terrifying, like a sharp claw.

Chen Xiao watched so quietly as the purple-haired man inserted his right hand into his heart and pinched his heart.

"Ahh He finds himself back in reality again. The sky is full of stars, and it is extremely bright. Where he is still a martial arts platform.

At some point, he broke out in a cold sweat.

Damn, was it just a dream? Why is it so real and terrifying. He touched his chest, his heart still beating violently.

Could it be that I opened it the wrong way?

The promised welfare of the traverser has become a crisis like the sword of Damocles? Chen Xiao wanted to cry without tears.

He found that Lux was looking at him strangely, and he couldn't help but blush, and pulled out a smile: "How is it, the breakthrough is complete?"

Lux nodded with a slightly red face and looked at Chen Xiao with a complicated gaze.

During her breakthrough, Chen Xiao was always by her side, which touched her very much. This kind of mood can't be expressed in words, it's like a warm current in my heart, warm and warm.

"That's good. I'm relieved. I'll go back first. Good bye. Chen Xiao was preoccupied, and he didn't notice Lux's abnormality, so he left in a hurry.

Lux looked at Chen Xiao's back, puffed out her cheeks, and suddenly the whole person was not good.

Chen Xiao did not return to his castle, but went straight to the laboratory.

The nightmare just now, he felt that it was not as simple as a nightmare, but a portent. The sense of crisis that haunted his heart made him restless.

Since there are fighting spirits and magic, demonic beasts and ghosts in this world, isn't it reasonable for things like demons to be. Since everything that crosses over can happen to him, there is nothing surprising about another demon asking for his life.

Chen Xiao comforted himself, and his mood gradually calmed down. His laboratory is already equipped with a lot of equipment and instruments, and a lot of chemicals have been collected, packed in glass bottles, and placed on shelves in different categories.

Chen Xiao looked at the bottles of chemical potions marked with chemical names and fell into deep thought. Perhaps, he needs to change, not only satisfied with what he knows, but also the knowledge of this world, it is necessary to understand it clearly.

Before that, he needed to tie Lux completely to himself. The pickled girl strategy must speed up the process.

He took out red phosphorus, black powder, iron powder, copper powder, table salt, alcohol, potassium chlorate explosive and other materials, intending to create a fireworks feast and make a romance.

I believe that under this unprecedented fireworks feast, Lux's heart has not been properly captured by him.

He still knows a little about the manufacturing process of fireworks, mainly black powder, and then with various metal compounds. When metal compounds are burned at high temperatures, because of the characteristics of their metal ions, they will produce a flame color reaction and emit a specific flame color.

Black powder, mixed with iron powder, produces red pyrotechnics. Mixing copper powder produces green fireworks, while mixing salt produces yellow fireworks......

After careful consideration, Chen Xiao began to make fireworks. Making fireworks is a kind of technical activity, whether it is the configuration of the propellant or the configuration of the pyrotechnic effect drug, it needs Chen Xiao to determine after many tests.

Black powder with potassium chlorate as a propellant produces huge propulsion when ignited, and it will not blow up the fireworks, so the proportion must be well controlled.

The effect of pyrotechnics is to mix black powder with alcohol, iron powder, etc., and stir it into beads.

Therefore, Chen Xiao's laboratory could be seen to be filled with colorful lights throughout the night, and thick smoke was billowing out of the laboratory window. Occasionally, there was an explosion, which startled the surrounding residents into insomnia.

After dawn, Chen Xiao found Sapp and handed him the design of the fireworks. The outer cylinder is made of iron. As for the inner cylinder, he needs to use pulp. After being introduced, he found the village's papermaker.

Feng Tu, a papermaker, is an old man over half a hundred years old. The paper products in the village are all from Feng Tu's paper house, and the paper made by Feng Tu is also sold to other places, and the craftsmanship is very good, and it has been passed down to this day.

Because Rodri Village is close to the Warcraft Forest and has a large number of tree materials, Feng Tucai set up the paper house in Rodri Village.

The paper-making house is not big, just a simple room, with a pulp trough and some rudimentary equipment for hanging paper, Feng Tu has always followed the ancient method of papermaking.

When Chen Xiao told Feng Tu about the pulp formula, Feng Tu was immediately excited, took Chen Xiao's hand, and said, "Lord Yushi, do you know papermaking technology?"

Feng Tu's papermaking process has been passed down for a long time, and only his disciples know the papermaking process. So far, he has not found a suitable disciple to pass on the craft of papermaking.

It's just that papermaking is too hard and you can't make a lot of money, so not many people are willing to do it.

Chen Xiao couldn't help but be embarrassed under Feng Tu's blazing gaze, he stiffened his head, smiled hahaha, and said, "Old Feng, I don't know how to make paper." Just understand some principles and formulas, and the specific operation needs to be done by you. ”

In his world, papermaking is one of the four great inventions of Chen Xiao's ancestors, and the ancient papermaking technology can be said to be general even if you don't understand it.

After handing over the fireworks mold to Feng Tu, Chen Xiao paid a lot of deposit, patted his ass and left. This old Feng has the heart of a craftsman, and like Sapp, he likes to challenge new things, so he readily agreed.

Everything was ready, and Chen Xiao hummed the song in a slightly better mood.
