Li Ming, a mortal architect, accidentally received an edict from the Jade Emperor. The heavenly palace was crumbling due to centuries of disrepair and was in urgent need of repairs on earth. He led an elite construction team to the clouds, only to find that the construction standards in the fairy world were very different from those in the human world. Li Ming's trump card tool is the "Universal Hammer", which looks ordinary, but in fact can automatically adjust the strength and shape according to different immortal materials. When he tried to use modern architecture to strengthen the Nantian Gate, he was accused by the heavenly general responsible for guarding it of "destroying the feng shui of the Xian family." Li Ming had no choice but to introduce the KPI assessment system into project management and set clear work goals for each fairy craftsman. For a time, the originally leisurely immortals began to complain. The fairies in Pantaoyuan were required to report their work progress daily, and even Taishang Laojun's alchemy furnace had to undergo "safety production inspections." The gods secretly caused trouble, but Li Ming used modern management wisdom to resolve the crisis. A decoration war between tradition and modernity, between the fairy world and the human world began.
