This is the provisional outline
One day, Xuantian discovered that the world he was living in was a script. The script stipulated that he should fall in love with a mortal woman, devote his heart and soul to her, and even help her become a god.
But he has someone he likes, a little childhood sweetheart he likes, and that really takes his heart out, and he doesn't feel good no matter what. But the script calls for Xiao Qingmei to fall in love with him but not be able to do so, and end up miserable.
It's a joke, if Xiao Qingmei can love him so much, then he can kill a few more evil spirits on the battlefield.
What a broken script, look at him first killing the heroine in that script, and then breaking the bad rules that restrain people. If the sky wants to stop him, he will fight with the sky. If the earth wants to stop him, he will fight with the earth. If anyone doesn't let him get along with Xiao Qingmei, he will take the risk of disemboweling him and even shoot him to ask for an explanation!
They fell in love in the cracks, with no results.
Intention: They fell in love in the cracks of time, with no results.
