The Taoist Master

Traveler Ou Gao discovered that the skills in the world of immortality were inefficient. He tried to use the earth's elementary number theory to optimize the skills. Unexpectedly, he discovered that the "Euclidean algorithm" he wrote down unexpectedly resonated with the ancient "mathematical way of heaven." Since then, he has embarked on a path of using mathematics as a sword to prove immortality and reveal the ultimate truth of why the world "cultivates immortality".
