Transmigrate and Battle the Immortals and Demons

Transmigrated into the Immortal-Demon War. The protagonist is the head of a modern taekwondo school with a little fame. He has regular features and a kind heart, always willing to help others. After an accident during a martial arts tournament, he transmigrates to an ancient world of immortal cultivation, into the body of Fairy Lei Yi, the eldest daughter of the pavilion master of Purple Immortal Pavilion, the foremost of the four great cultivation sects. Fairy Lei Yi has been a mudblood since childhood, with barely any immortal power. In truth, she has a powerful formation within her, but it has simply been sealed away. Lei Yi herself doesn’t know this. She doesn’t want to be mocked or remain powerless, so she secretly descends to the mortal world to gain experience. There, she encounters an injured prince of the demon realm and begins to care for him. They meet, fall in love, and fight one another. In the end, the Immortal-Demon War begins.
