Yang Lin, a mobile phone salesman who has studied Chinese martial arts for three years, is fortuitously transported to a world of cultivation by a five-colored ball of light. Watch as he leverages his past life's knowledge of math, physics, and chemistry to cultivate a scientifically grounded immortality. His martial arts, especially Tai Chi, rise to prominence in the world of cultivation. This scientifically grounded immortality story is well-written and logically coherent.
