Chen Mo, a modern civil engineer, died suddenly due to continuous overtime work. He accidentally traveled to the world of Journey to the West and became a low-level heavenly soldier in heaven. He found that the heavenly system was surprisingly similar to the modern workplace - strict hierarchy, numerous factions, and prevalent formalism. Relying on the "workplace survival skills" he had learned through hard work at construction sites, Party A, and government departments in his previous life, he began to survive in the cracks of Journey to the West. He used project management, interpersonal relationships, and bureaucratic wisdom to climb up step by step from a small gatekeeper at Nantianmen.
