, I recommend the following apocalyptic novels: 1. "Dominate the World: Ultimate Pet Evolution"-The male protagonist accidentally obtained the invincible pet system, starting the road of counterattack. The little snake evolved and became an invincible existence. 2. "Invincible at the Beginning of Doomsday"-The male protagonist forced out his potential in the apocalyptic disaster and obtained the strongest system. He was invincible all the way. 3. [Invincible Instant Kill Upgrade]-The male protagonist is a Heavenly Emperor. After his rebirth, he obtained the Invincible Instant Kill System and crushed everything along the way, becoming an invincible existence. I hope you like my recommendation, Mwah ~😗
