How to Kill the Main Character in a Martial Arts Novel

Dear fellow readers, you are all the protagonists!

As we all know, in martial arts novels, there is an unshakable law - the invincibility of the protagonist. If a protagonist dies in a martial arts novel, there can only be two reasons: 1) He is not the real protagonist, but a pseudo one (such as Zhang Cuisan). 2) He is not the sole protagonist (such as Xiao Feng).

But now, you are the main antagonist in a wuxia film that has attracted nationwide attention, adapted from a famous martial arts writer's masterpiece with an investment of hundreds of millions. Your mission is to kill the protagonist, the true and only protagonist, the handsome, debonair, elegant, and charismatic male lead. Obviously, this is an impossible task. You clearly understand that the director is making things difficult for you because you dated his favorite actress. As a seasoned martial artist, you certainly have heard of the invincibility of the protagonist, and know that historically it has never failed. So, should you just give up? Admit defeat? Wait obediently for the protagonist to kill you?
