My name is Lu Chen, I was originally a tactical consultant of the special forces, and I traveled to the world on the edge of the wasteland. The warlords here are divided and the government exists in name only. I am forced to issue survival tasks by the system every day. Failure to do so will put my life in danger. By accident, I was bound to the daily check-in system. By completing tasks, I can upgrade my physical functions, unlock medical modules, and hack into enemy networks. With the help of the system, my physical strength and intelligence are far beyond those of ordinary people, and I have also made friends with hackers, psychologists, field commanders and other partners. I went from fighting alone to forming a team, completing high-risk missions and uncovering world conspiracies along the way. In the end, I integrated the core of the system, gained the ability to fine-tune reality, and became a walking law, protecting the stability of the world and allowing civilization to continue.
