A college student who spent high school watching others get ready for college, attend college, and graduate from college transmigrates into the body of a young Taoist priest in a parallel world.
He never expected a System to appear. Instead, he fused with another transmigrated soul. That soul turned out to be a Great Luo Golden Immortal who had transmigrated in reverse, from the mortal world.
In the first, second, and third years of high school, the three souls must become one. Only by cultivating the heart and experiencing the everyday world can he attain the Great Dao and return to the immortal realm.
Watch as the young Taoist, with the power of an immortal, experiences the joys and sorrows, love and hatred of the human world during high school. He will attain the Great Dao and return to the immortal realm.
