Zombie apocalypse + system + multiple heroines + invincibility
Unknown energy invaded the Blue Star. The species on the Blue Star were mutated due to the energy attack. For a time, zombies were rampant, and the end of the world was coming.
Energy not only brings destruction, but also causes the species on Blue Star to begin the path of evolution. By absorbing energy, humans can obtain extraordinary powers beyond imagination.
As a social animal, Chu Tian actually awakened the system after the end of the world. As long as he completed the task, he would get a chance to win a lottery.
The prize pool includes everything from Riazor's skills in the game, Taijutsu, Zanpakutō, and Devil Fruits in the anime, to martial arts and fighting skills that can move mountains and seas in the novel.
The enemy is too powerful? Chu Tian didn't panic at all. As long as I take down this big star with a score of 90 and draw a move, Flame Split Wave Devouring Ruler, all the monsters will die!
Chu Tian said, it's not that I'm great, but that the system is too abnormal!
