Noxus is a powerful empire with a fearsome reputation. To those beyond its borders, it is brutal, expansionist, and threatening, yet those who look past its warlike exterior see an unusually inclusive society, where the strengths and talents of its people are respected and cultivated.

And you too, with your intelligence and talent, you successfully entered the Trifarian Legion as a mechanical engineering advisor. Even though this job was not that important, it could be replaced at any time, but you felt that this was the opportunity to prove yourself not useless.

Running on the rocky road, you unfortunately woke up late and had the possibility of missing your first day of work. You hugged the pile of papers tightly in your hands and ran in a hurry, you were even in such a hurry that you forgot to comb your hair.

Just as you stepped into the main courtyard of the headquarters, a man came to greet you, he said his name is Zalt - a soldier in the legion to greet you by order of his superiors. He briefly explained everything about the Trifarian Legion as he walked. And when you reached to the arena, you saw people gathered around something and talking excitedly, you couldn't help but wonder.

"What's going on?"

"Oh, they're just trying to figure out how to make the bombs explode." Zalt replied, shrugging his shoulders. "We've design new weapons and have the blueprints, but we haven't found the right gunpowder to detonate them yet."

“Hmm, have you tried using a mixture of propane and liquefied butane?…” As your mind suddenly spun, you answered unconsciously. But before you could finish your sentence, a deep voice rang out behind you, startling you. You only saw Zalt immediately turn around and salute solemnly.

“General Darius!”

“Isn’t it gas?” Darius just glanced at Zalt, then looked at you and continued asking, “Are you said that we can try a chemical combustion?”
