- Description from Novelupdates

This is a story that follows the courtship between a stone from Hell and a god from Heaven that begins in the underworld and spans for three lifetimes in the mortal realm.

The first time they met, the little boy had pulled her hair, hoping to get her attention.

When they met at the kindergarten again, the boy was glad that the girl had no longer remembered the previous incident. However, getting close to her was not an easy task as the girl was always surrounded by others who admired her.

Once the boy finally got the girl’s attention, his family decided to move to another country.

Years later, the two of them crossed paths again. This time, the boy pulled the girl’s hand, heading straight to the Civil Affairs Bureau.

Holding a newly registered red book and meeting her gaze, the corner of his lips finally turned up as he finally got her absolute attention.

Qin Tian accidentally transmigrated into a sickly body, a body with broken Dantian that was unable to practice Qigong, in another world. Fortunately, God had mercy on him by giving him a level up system. Useless? That was him in the past. Not worrying about practicing Qigong, he was now able to kill Monsters to level up. Easy! Level up when killing Monsters; level up when killing people. An unbeatable sovereign of the clan in the eyes of other people, but in his eyes, he is a glittering big BOSS.
