Lin Yu was originally a student of the Department of Modern Architecture, but traveled to a different world of Feng Shui and became a disciple of the Lin family.
When the Lin family inspected the feng shui of their ancestral home for a wealthy businessman, the elders planned to use traditional methods.
However, Lin Yu relied on modern knowledge and new understanding of Feng Shui to believe that the incoordination of lighting, ventilation and aura was the problem.
He proposed a new plan, which was doubted by his elders, but was implemented with his persistence and the consent of the wealthy businessman. After a few months, the effect was remarkable, and he also emerged in the Lin family.
