I have forgotten the name of what I believe to be an manga, manhwa, or anime where one of the characters not the main but member of the MC party who wields a spear exclusively through the usage of his finger muscles. I believe it was because he could not use either shoulder or back crippling when younger.
Undefeated God of War Li Xu? I think it was called the character , he had a Silver Spear inheritance or something.
Since someone already beat me to it I'll say Peerless Martial God. Hate you Lazybum0 for like 7.36 seconds I hate you.
That is precisely it Undefeated God of War. The silver spear inheritance I remember now. Thanks Lazybum0
