I, the Stake, Want to Die

I am a wooden stake, the one who has been beaten by players for ten thousand years in the novice village. Later I awakened and traveled to the world of immortality. They can fly with swords, burn mountains and boil seas, and pursue immortality. And I only know one thing - not to die. If I get chopped with a knife, I will survive. Burned by fire, I live. I was chopped into ashes by the catastrophe, but I am still alive. So, I want to die. Who can kill me?
