The correct way to open the sprite

If Feng Yu wants to make a simple human-powered machine tool or an animal-powered machine tool, among other things, the low-precision gears and transmission Dick can help him solve it, but the high-hardness alloy cutter heads and drill bits of the machine tools are the domain of the alchemist.

How could Clarence, who was half a student of Feng Yu, refuse Feng Yu's request? He agreed without thinking.

This requirement has been met. As Clarence who likes to study metal alloys, he is not good at Feng Yu's super gunpowder research. Feng Yu also knows Clarence's expertise and does not count on him. He came here today just to let Clarence The alchemy laboratory helped.

In fact, it's his fault for thinking things too simply. This world doesn't even have the two basic sciences of physics and chemistry. Inventing things depends on luck. It's better to expect them to develop efficient gunpowder than if Feng Yu did it himself.

Feng Yu couldn't wait any longer, so he came over by himself. Not only did he have to borrow Clarence's laboratory, he also had to ask everyone in Clarence's laboratory to be his assistant, and then he slowly revealed the truth.

After listening to Feng Yu explain the principle of gunpowder, Anthony found him a method that could replace high-efficiency gunpowder, and that was the magic circle.

The violent wind of wind magic that reduces the power can be released through the micro-carving magic circle, which can act as black gunpowder and push the projectiles out.

However, there is a problem with this thing, that is, the primer of the magic circle is magic crystal. The value of this thing is as high as the whole continent. Who doesn't know that this thing is only a few dollars more expensive?

Although the elves are still a bit old, they can't withstand such consumption.

You must know that firearms are the younger brothers of thermal weapons. What will happen to the God of War cannon? If you can shoot a top-level magic crystal, it is better to send the magic crystal to magicians and let them use new magic to fight.

After knowing Feng Yu's purpose, Clarence not only showed no displeasure, but was very happy. He was looking forward to experiencing the operation mode of Feng Yu's laboratory in person.

Although he was also moving closer to the experimental mode mentioned by Feng Yu, he could never find that silky smooth feeling, and instead felt awkward everywhere.

Clarence called everyone in the laboratory, including the apprentice who was following Feng Yu's class. Through Clarence's introduction, Feng Yu knew that this half-elf boy who was being bossed around by Clarence was actually Is an official magician.

Feng Yu asked Clarence if they had the kind of liquid that could quickly corrode metal, and got an affirmative answer. There were quite a few, and there were three types.

After Clarence asked his assistants to get the liquid, Feng Yu arranged for them to label the container with the name of the liquid, and then walked through the process as requested by Clarence to make it easier for Clarence and his assistants to learn.

Feng Yu took out a blackboard and wrote on it:

The purpose of the experiment is to prepare high-efficiency gunpowder.

Method: Acidic corrosive liquid soaks cotton fiber textiles.

After Feng Yu finished writing, he said: "My profession is far from alchemy. I have only heard about this formula, so I have to trouble everyone to help me experiment."

After Feng Yu finished speaking, he was not polite and arranged for three kinds of acids to be soaked in cotton textiles alone or mixed, and each person was responsible for one kind.The damp textile is heated with fire and the reaction is observed.

After assigning the experimental projects, Feng Yu waited for the results.

Maybe the fairy sister who sent Feng Yu here didn't want to see him fail. This kind of nitrocellulose that only works on earth was actually produced in other worlds, although Feng Yu didn't even know what the liquid was made of. .

Good news came from the young man in charge of mixing the two liquids. He reported to Feng Yu and Clarence that after the liquid he was responsible for soaked the cotton ball, the damp cotton ball exploded after being close to the flame. In addition to extremely rare ash, It was burned to the ground, as if it had disappeared.

Feng Yu immediately recorded the two liquids and asked Clarence whether these two liquids could be produced on a large scale. After getting the affirmative answer, Feng Yu was very happy.

After repeated experiments to confirm the effect, he asked his assistant to re-blend the mixed solution, soaked a large number of cotton cloth fragments, and took out three sealed porcelain bottles from the box he brought.

This was created by Feng Yu who worked hard on the Internet. The porcelain bottle contained high-level alcohol that was distilled after consuming three large tanks of Allen's swill.

By the way, Feng Yu felt that using the pottery vats he fired to brew swill wine for Allen was really a injustice to those vats.

Feng Yu poured out some alcohol and put a soaked cotton cloth in. Sure enough, the wet cotton ball slowly dissolved.He divided the solution into several parts and tested several stabilizers he brought. Finally, one of them turned the solution into a gel.

Feng Yu carefully took out the gelatin, took out a small amount and pressed it into a sheet, then cut it into thin strips and dried to harden.He cut the resulting hardened strips into small particles and compared the ignition effect with equivalent gunpowder.

It can be seen with the naked eye that the power of the explosion of small black particles is much stronger than that of dwarf gunpowder, and it is not like the thick smoke of dwarf gunpowder. Only a small amount of green smoke comes out. This makes Feng Yu feel like he is destined. The thrill of something accomplished.

He also arranged for assistants to prepare different gunpowder particles for comparison by adjusting the amount of alcohol solution and the dosage of stabilizer, and finally obtained an obviously more suitable ratio plan.

Clarence stood aside blankly and said: "The dwarves have not updated the recipe for hundreds of years, and you just made it so easily."

Feng smiled modestly and said, "That's because my hometown has already had this plan. Otherwise, who would have thought of using liquid and cotton to make gunpowder?"

Clarence nodded: "It's not right either, so how did you come up with it?"

Feng Yu smiled and asked Clarence: "If you happen to touch these two liquids and spill them on the experimental table, and there is a cotton rag on the experimental table, what will you do?"

Clarence said in surprise: "After wiping it off, the rag that absorbed the corrosive liquid could no longer be used, so I threw it into the stove and burned it."

"Yes, that master did the same thing. Before he could throw the rag into the stove, the high temperature ignited the rag. After the explosion, a large ball of rag was not even ashes left. How could this not be allowed to the expert? The master of gunpowder was astonished.

So this highly efficient gunpowder was born in an extreme coincidence.

However, the master dried the rag directly and made it into gunpowder. The gunpowder was very dangerous and could even explode on its own.The latter method of dissolving and making gunpowder into lumps is the masterpiece of another master.

It was these two masters who enabled us to use powerful and safe smokeless gunpowder. "
