The Villainous Master: From the Start, I Instantly Slay the Chosen One

[Villain] [Apprenticeship critical hits] [Villain's golden finger] [Decisive and ruthless] [A disciple who defies their master] Xie Tian Zhenjun of the Tianyuan Holy Land suddenly discovered that all his disciples were female Villains! The protagonists all have golden fingers. What can he do? Luckily, he can be his disciples' golden finger! A bone-stealing protagonist destined to become the Primordial Great Emperor? Then he'll steal his double pupils too! A reborn protagonist destined to rule the Nine Realms? Strip away his memories and destroy his humanity... no, his body. Leave no loose ends! As for the protagonist from the annulled-engagement trope who appeared at the very beginning... Too weak, and there's nothing worth taking. Just kill him!!!
