So Chen Xiao began to assign work. Pen % fun % Pavilion www.biquge.info

"Lux, go collect the ashes from the fires in the kitchens of each house, the more the better. When he said this, Lux was stunned, and asked her to collect the ashes.

"Are you sure you're not kidding? Let's hurry up and figure out how to set up some traps to hunt monsters. Lux pursed her lips, her face full of reluctance. However, under Chen Xiao's death and begging for nothing, Lux still pulled a sack on his shoulder and went out.

"My dignified bronze warrior, Lord Lux, actually wanted to go to the door to dig up ashes, and no one believed me. Lux muttered, reluctantly knocked on a door, and then said in a stiff voice, "Do you need to clean up the dust in your kitchen?" ”

This kind of rhetoric can only be imagined by Chen Xiao. However, Lux managed to get inside the house and began digging up the ashes.

As for Chen Xiao, he was not idle. He dragged a sack and went to the pig and chicken coops in the village to pick up some fluffy black and yellow soil and collect it. These soils are usually rarely rich in nitrates and are a good source of nitrate.

This collection is most of the time, and collecting nitrate is hard work, and Chen Xiao is almost tired like a dog.

He didn't dare to ask the old man Sap to help, Sapken lent him a place, and it was already benevolent and righteous to provide sulfur ore, if Chen Xiao made any more excessive requests, maybe he would be kicked out of the iron shop.

Besides, Sapp also has its own tasks.

At noon, he forced himself to swallow two pieces of hard and dry black bread with water, rested for a while to recover his strength, and then began to prepare for the follow-up work of making nitrate.

Lux dragged back with a large bag of ashes on her face. She began to doubt her life.

"Why should I listen to this stranger!" Lux asked herself. She entered the blacksmith and walked through the shop into the courtyard behind the blacksmith.

I saw Chen Xiao holding a pile of dirt and pouring it into an iron pot, and there was still a fire burning under the iron pot. His white shirt was already covered in mud, black and dirty, and ugly. He was sweating profusely, his muscles sticking to his clothes, revealing the ribs in his chest. The heat of the flames made Chen Xiao's face flushed, and the beads of sweat on his face were even more dripping.

Suddenly, Lux's nose was a little sour.

Although she didn't understand what Chen Xiao, a foreigner, was thinking in his head and what he wanted to do now, Lux suddenly had a kind of expectation. This feeling is like being touched at the heartstrings, and a strange feeling passes through the heart.

Seeing Lux stunned at the gate of the courtyard, Chen Xiao ran over to take the sack, weighed the weight, and said very happily: "These should be enough." Thank you, Lux. Leave it to me. Give me another half day. ”

Lux nodded, then walked to the chair next to him and sat down, quietly watching Chen Xiao who was working in full swing.

"What can you do with all this dirt and ashes?" Lux never understood. At this time, Sapp came out of the shop, threw a metal tube to Lux, glanced at Chen Xiao with a strange look, and said quietly: "I want to know too." ”

Lux looked at the rounded iron cylinder in her hand, then at Sap, but did not speak. The barrel was the size of three fingers, cylindrical in shape, one palm-long, and had an opening at one end. The skin of the tube is not thin, but it can be pinched with a little force, and this skill can be done by Sapp.

Sapp said in a deep tone, "This is something that the kid designed. Lux, what's the origin of that guy?" he didn't know what this thing was doing in the end, but the design and concept were definitely not something that ordinary people could imagine. Moreover, he had a strange premonition that perhaps he had created something unavoidable.

Lux shook her head.

"I didn't know that when that guy appeared on the shore, we were ambushing a wave of fishmen. It looks like it was drifted from the sea. ”

"A stranger drifting over the sea?" Sapu glanced at Chen Xiao, just turned around and went back to the shop, he still needed to continue to build more of this kind of iron cylinder for Chen Xiao.

Chen Xiao added the nitrate soil and plant ash to the iron pot in a ratio of 7:1, then added water and began to boil. Nitrate is rich in nitrate, and plant ash is rich in potassium carbonate, and after the two are boiled, a large amount of potassium nitrate will be produced, that is, saltpeter. As long as the boiling water is filtered and evaporated, it is the original saltpeter. With the current equipment, Chen Xiao can only do this.

Half a day later, Chen Xiao collected almost seven or eight catties of saltpeter.

Next came the most important step, the configuration of black powder. As a chemical dog, the simple and primitive formula of black powder has penetrated deep into the bone marrow, and it is clear what proportion and what effect it has.

And the iron tube built by please Sapp has also been completed, and Chen Xiao plans to complete the rest of the work by himself. Because it is a secret related to the manufacture of black powder, it cannot be divulged. After locking himself in the house, Chen Xiao began to configure black powder.

The charcoal, sulfur, and saltpeter that are ground into powder are mixed in a ratio of 1:2:3.

Then, a strip of cloth soaked in potassium nitrate is rubbed to form an easily flammable lead and inserted into the iron cylinder. Finally, it is filled with the prepared black powder.

After all this was done, it was already late at night. The dark night sky is only dotted with stars, and the occasional night breeze makes a whining sound, as if a demonic beast hidden in the darkness is beating on people's hearts.

The cold of the night made Chen Xiao shiver, and he remembered the huge head that poked into the room through the window last night, and goosebumps rose all over his body. When he saw the ten "earthen detonators" displayed in front of him, he couldn't help but breathe a sigh of relief.

Although the earthen detonator was made, he still needed to find a way to make the fire that he could carry with him.

In his time, fires were still made of flint, and in addition, magicians who emitted flames were also moving fires. However, neither option is feasible for Chen Xiao.

He needed to make a spark that he could carry with him—a fire fold.

There happened to be some saltpeter and sulfur left, and Chen Xiao planned to make full use of these raw materials to make a fire fold. The preparation of the fire fold is actually very simple, and there are not many materials needed, for the current Chen Xiao, the fire fold is the best choice.

The night passed quickly.

When the sun rose quietly and the warm sunlight fell on Chen Xiao, he realized that he had fallen asleep unconsciously.

He was covered with a blanket.

After folding the blanket, Chen Xiao couldn't help but show a moved gaze. has been single for more than 20 years, and no one has ever given him this kind of warmth except for his mother who will cover himself with a quilt.

But now there is a man.
