System: I Made You Invincible, and Now You’re Killing Me?

In 2024, an unidentified meteorite strikes Blue Star. Its explosion turns the world upside down. Mutated demon beasts and creatures from other dimensions begin appearing, and humans start awakening abilities of their own. They become known as Demon Hunters. Li Zirui is an E-rank Demon Hunter, the lowest rank of all, and the weakest among those who hold it. Known by the special title "the Demon Hunters' worst player," he encounters a strange cave while out hunting demon beasts with a team. Almost everyone in the party is killed after they enter. At this moment of life and death, a System notification rings out in his mind. On the brink of death, he miraculously survives with the System's help. Did the System choose him, or did he choose the System? Is the System using him, or is he using the System? Could all of this really be a coincidence? Can he escape his reputation as the Demon Hunters' worst player and become the strongest Demon Hunter?
