Reincarnated as an Alchemist - If i have no cheat then, i just have to make one

I landed on the ground by using some wind magic to reduce my momentum. When my feet touched the ground I saw something surreal. The demon I just shot out from the tea room was landing on the ground head first and now it had its upper half stuck inside the earth.

"Acha.... It seems like this guy is just a grunt."

I said.

"That's exactly right, human."

I heard a heavy voice from the sky. A demon with bat wings was hovering in the air.

"Oya? I never thought that a big shot will appear."

I said.

"Heh! Say whatever you want. I will kill you here and now."

He said.

"That would be troubling so I will refuse it with all my might."

I said.

"Feel free to do that. But, that's futile. A weak youngling like you can't defeat the mighty me."

He said.

"But, firstly..."

I stretched my neck.

"Can you get down? It's a pain to look upward for long time."

I said.

"Whine whatever you want. I know that you don't like the mighty me looking down on you right?"

He said arrogantly. I frowned when I heard him. Judging from his reaction and responses just now, I could guess that he is that kind of higher ups.

"But, you're wrong if you said I'm a human."

I said.

"Mu? You're not?"

He was surprised.

"Look at the broken window over there"

I pointed upward. He looked up at the broken window.

"So what of it?"

He asked.

"There's no human who can jump out from that height unscathed."

I said.

"Mu? That's also true."

He said.

"Also, I am an acquaintance with Filma-dono. If you don't believe it, you can ask her."

I said.

"Filma-sama, you said?!!"

He was surprised.

"Filma offered me some interesting offer the other day. I asked her to give me some time and I'm here not to answer her. I heard she's looking for the hero's companions so I waited her to pick that elf wizard but to think she will send some grunts instead. This is troubling."

I said.

"Mu? If I were in your shoes that was certainly troubling."

He said.

"See? Ah. Actually I'm tired of waiting. Can you tell me where Filma is? Instead of waiting for her uncertain visit, I'll go to her place instead."

I asked.

"Ah, Filma-sama is in the demon lord castle."

He said.

"Where that might be?"
