I Became a Demonic Spear

The Protagonist Isn't Human, Never Takes Human Form, No Romance, No Ambiguous Relationships

The protagonist shouldn't be human, there should be no romance or love interest, and they shouldn't take human form or meddle in other people's business. They should be decisive, like "Evolution Begins with a Big Tree".

An Invincible Lone Wolf, No Female Lead, No Do-Gooding, Decisive and No Showing Off

Invincible, no female lead, not a bleeding heart, decisive and ruthless, and not a show-off.

Novels Where the Protagonist Is a Weapon That Everyone Fights Over

Any Books Where the Protagonist Turns Into a Weapon? Please!

They can turn into anything, as long as it's a weapon. Books, swords, knives, spears, anything goes.

Looking for Traditional Xuanhuan Cultivation Novels: No Overpowered Leads, and a Smooth Plot. Any Suggestions?

I'm looking for books like "The Last Scion of a Massacre: Mining Spirit Ore in an Immortal Sect". Mortal cultivation stories, with Qi Refining, Foundation Establishment, Nascent Soul, and so on. Any good ones?
