Gunpowder

"No one should get close to this black powder; it is a dangerous substance, so we should keep this restricted highly for the trained people," Garnt ordered as he kept looking at the black powder, which was the newest blueprint that Garnt got from his system.

"What exactly does this powder do, Garnt?" Rona questioned, confused. He smiled as if he had something surprising waiting for them. Ayra and Gundo were also there, but they didn't know what to expect. Only Unami had a slight idea because she was the project head of this black powder thing, which was a really hard project since they had to find some rare raw material for it.

But even she hadn't seen the use of this powder, so she was excited to see what she was working on.

[Show them, Garnt. This is one of the biggest inventions we have had in recent years, but also one of the most dangerous ones, so be careful.]

Eva gave her warning, and Garnt accepted it without showing any hesitation.
