[Apocalypse + infinite flow + System] No naive heroics, decisive and ruthless.
The apocalypse arrived. Humans turned into zombies, and things from imaginary worlds appeared in reality. Earth became a playground for the apocalypse.
On the day monsters attacked his camp, Xiao Minghao was betrayed by the player he had followed and shoved into their midst. After enduring the agonizing pain and betrayal, he unexpectedly returned to a time before the apocalypse began. Not only did he become a player and awaken a talent he hadn't possessed in his previous life, but his talent was seven times stronger than anyone else's! “Talent activated: Master of the Seven Virtues (Sealed)!” He also drew an SSS-rank skill, “Supreme Summoning”! And so, relying on his powerful talent and skills, Xiao Ming began his journey of revenge!
Sure, killing anime characters grants you their abilities; that's how it should be.
It's not bad; the idea is novel, and it incorporates some game and movie elements into the post-apocalyptic setting.
Novel theme, keep it up!
