The end is inevitable

The plot is based on Slavic tales about "Koshchei the Busmer". This is a supervillain whose essence is to do evil. He is immortal, but you can kill him. His death is at the tip of a needle, a needle in an egg, an egg in a duck, a duck in a hare, a hare in a box, a box on an oak, and an oak on an island. It's his kryptonite. Today, Koschey is sitting in a bunker and killing Ukrainians, but his end is inevitable.
