Can You See Me Now?

When you're given an opportunity to resurrect in another world with magic, skills, levelling and based within a medieval world, remember the Assassin Class is your favourite in video games and get asked by the divine entity ruling over reincarnation what you want, within reason, in this fantasy world, what do you say to them?

Well, Benjamin Hēihǔ has the answer to that:
"I want to be an assassin with the Chinese Stealth Suit, fully upgradeable and adaptable for this new world, with my very own Chinese Officer's Sword and I want YOU to be with me every step of the way!"
Which is exactly what he yelled to the deity before him, more eager than he had ever been before.

With a bewildered deity by his side as his advisor, what shenanigans will this English/Chinese boy get up to?
