It Makes Sense for This Alchemy to Be Used to Make Guns, Right?

My name is Claude, and I am a time traveler. After my performance was hit by a dump truck as usual, I came to a Japanese fantasy world and was born into an alchemist family. Originally, I thought that after time travel, I would become a genius and reach the pinnacle of life. But I don't know why, but it's difficult for me to create traditional alchemical products. The only way I'm more proficient is to change the shape and composition of objects. Later, after observing the alchemy process of other alchemists, I concluded that the reason was that I was not good enough. But fortunately, my memories of my previous life became extremely clear after I traveled through time. Since traditional alchemy products can't be processed well, they can only give people in other worlds a little shock with firearms.
