I learned skills in a different world

Sulfur, saltpeter and charcoal were all very easy to find. As long as Shen Fangshi gave the order, someone would quickly prepare everything. No one suspected anything at all, they just thought he was going to make some kind of artifact again.

Shen Fangshi has his own dedicated studio in both workshops. Because of the energy protection shield, he is not afraid of explosions, so he plans to experiment in the studio.

After all the materials were prepared, Shen Fangshi was not a person who liked to procrastinate. He closed the door of the workshop and placed the energy protection shield on the workbench.

This kind of protective shield can be activated instantly with mental power to cover the source of the attack output so that the energy does not leak out. It can also be worn on the body and automatically activates to cover itself when in danger, so that the outside world cannot attack itself.

Perhaps because of his good luck, he successfully mixed the gunpowder in only three attempts. After each mixing, Shen Fang would first activate the protective cover and then ignite the gunpowder.

After successfully detonating the gunpowder for the third time, Shen Fangshi tried several other ratios, and finally determined that the content of sulfur and nitrate was one to three. At this ratio, the gunpowder was the most powerful and explosive.

It's getting late today, and Shen Fangshi is planning to find an open place to test it tomorrow to see the specific power and to give the gunpowder a clear path.

Yesterday, due to the function of the silent energy protective shield, other people in the workshop did not know about the gunpowder.

Therefore, when Shen Fangshi brought a dozen apprentices and several military craftsmen to a deserted place, no one knew why, but because Shen Fangshi's prestige was high enough, no one said anything.

The apprentices were a little uneasy. Yesterday, Mr. Lin gave them a homework assignment. They were asked to work in groups of five to make a wooden plowshare. They thought it was simple at first, but when everyone assembled their own parts, they were dumbfounded.

Why can't they match? It's obvious that they have already determined the size before, but it turns out that either the joint here is too big, or the mortise and tenon joints don't match up there.

So today when Shen Fangshi brought them out, they felt a little guilty. Mr. Lin must be very disappointed in them. I remember yesterday that Mr. Lin said that this is a basic skill that everyone must master proficiently. If any team fails to complete it, there will be penalties.

Are they brought here now to beat them?

Shen Fangshi didn't pay attention to the worried expressions of the apprentices. He said, "Everyone, I brought you here today to test something. It may be dangerous, so please stay away."

When everyone heard this, they felt confident and immediately became excited. They knew very well that the weapons Shen Fangshi made were very powerful. The thing they were going to test today was dangerous and must be another powerful weapon.

Shen Fangshi took out something in the shape of a bamboo tube. Although gunpowder made from iron tubes was more powerful, even with iron ore, it was still necessary to save some money.

Although this bamboo tube did not look like a dangerous weapon, no one showed any doubts based on their trust in Shen Fangshi.

Mo Yuting said: "Mr. Lin, since there is danger, why not let me test it."

Others also stepped forward to do the test for Shen Fangshi. After all, Mr. Lin was much more important than them, so nothing could happen. Moreover, they had known Mr. Ai Zhonglin since they had been together for so long.

Shen Fangshi felt a little warm in his heart, but still refused: "You have never seen this thing before. It is prone to accidents, so let me do it."

Seeing that the others still looked worried, he paused, smiled and reassured: "Don't worry, you'll be fine if you stay far away. Cover your ears later."

After the previous protective cover was used up, he bought another one and put it on, and everything would be fine.

Seeing that they all obediently covered their ears, Shen Fangshi took out the fire stick, opened it, blew on it, and lit the fuse.

After lighting it, throw the gunpowder barrel away as it sinks.

--"boom."

A loud noise spread, and earth and rocks flew.

Everyone stared at the huge crater in front of them in stunned silence. The smoke and dust left after the explosion had not dispersed for a long time.

After a while, Lin Xiaotao put down her hands covering her ears and stammered: "Just now, was the ground shaking just now?"

Mo Yuting: "Yes, right."

As if the silence was broken, the others suddenly started discussing, "It must have been thunder from heaven."

"Is Mr. Lin an immortal? He can actually draw thunder from the sky!"

"It must be!"

Shen Fangshi smiled and explained: "This is not an earth dragon turning over, but gunpowder."

Lin Xiaotao asked curiously: "Gunpowder?"

"Yes. Gunpowder can be used to make various weapons and can also be used to dig mines."

"This powerful gunpowder actually has so many effects."

"Yes, but you have to be careful when making gunpowder, otherwise it will explode easily."

Hearing what Shen Fangshi meant, was Shen Fangshi actually planning to teach them this magical skill? Everyone else held their breath and didn't dare to ask more questions, for fear that they would get the wrong idea.

As long as the gunpowder is mixed, it is actually relatively easy to make a firecracker, after all, its structure is simple.

After making it, Shen Fangshi first tried it.

The craftsmen watched Shen Fangshi make this thing called a fire gun.

They didn't expect that something like a steel pipe could be so powerful. Even though they had seen the power of gunpowder before, they still endured it when they saw that such a small steel pipe could easily penetrate an archery target and shoot a hole in a tree in the distance. He couldn't help but look in wonder.

Although the others were satisfied, Shen Fangshi felt that it was still a bit lacking. This gun was still too crude, had high impact, and was not lethal enough.

Looking at the fire gun in his hand, Shen Fangshi thought of the guns of later generations. Maybe he could try to improve the fire gun. The fire gun made from the fire gun drawings provided by the system was more troublesome to load. The bullet speed and shooting accuracy were not high. It attacks from a distance by firing bullets, but it has a shortcoming in close combat.

As far as he knew, the ones that were more advanced than fire blunderbuss were improved bird blunderbuss, double-shot blunderbuss, etc.

The bird gun is composed of a gun tube, front sight, rear sight, trigger, gun bed, curved gun holder and other parts, and is fired with a match rope.

The trigger of the gun is shaped like a metal hook. When firing, the shooter looks at the crosshair through the rear sight and aims the crosshair at the target. The shooter first lights the match rope, then pulls the trigger, ignites the gunpowder, and shoots the projectile. Then load the ammunition and fire continuously, which improves the rate of fire and hit accuracy, and increases the range and lethality.

The mother-child gun is an individual gun composed of a mother gun and a child gun equipped with a standard spear. The front end of the mother blunderbuss tube can also be equipped with a short sword. The sword body is one foot three inches long and the blade is five inches long. It is usually installed in a wooden box. When the dagger is inserted into the mouth of the tube, the whole blunderbuss and the sword are five feet long in total. . When firing, the four sub-guns are loaded into the mother gun in turn and fired in sequence, greatly increasing the rate of fire. If the blunderbuss is used up, the dagger can be plugged in and used as a gun to fight the enemy in close combat, which greatly increases the practicality. 1

Main mission 5 has not been completed yet, and the fire gun has just been built, so it will take some time to get the recognition points.

Now Shen Fangshi has roughly figured out the way to gain recognition in this world, which is to let more apprentices know the power of the tools they make.

An ordinary person has one hundred recognition points, and an apprentice has two hundred recognition points. Now just the craftsmen, apprentices and guards of the two workshops, his recognition points have reached tens of thousands, let alone There is also the remaining approval value from the previous task, which can be used to offset the next task.

Shen Fangshi put the task aside and slowly began to improve the gun.

With the prototype in hand and the memory of his previous life, he soon had ideas for improvement.

Shen Fangshi drank a concentration pill, tried to draw the structure of the bird gun and the mother-child gun, and then adjusted it bit by bit.

Once these are manufactured, his tool manufacturing expertise is estimated to reach 41% and above.
