Li Mu, an ordinary social animal, was suddenly bound to the 'omnipotent system'. The system says that if there are tasks, there will be rewards, but every task has its pitfalls: letting your boss praise you in public, letting the subway girl take the initiative to join you, and becoming brothers with the security guard downstairs. Li Mu thought this was the way to reach the pinnacle of life, until he discovered that dozens of previous hosts had failed all missions and were wiped out. There is no time to explain - this is a triangular game between the system, the host and the mastermind behind the scenes. Li Mu needs to rely on his cool skills and thick skin to fight his way out under the harsh rules. He's not the strongest, but he's the best at bugs. Urban system flow, easy to counter-routine, fast-paced, and intensively refreshing.
