Thorn Song

This text has no male lead, no romance.
The female lead is slightly timid in the first volume, a bit infatuated in the second, and from the third volume onwards... life seems like a Siberian Husky.
Below is the sequence of volumes, if there are chapters missing, they're probably blocked.
1 Who's best at murder and dismemberment? Look in the suitcase for jackals and wolves.
2 I can handle tutoring, even rocks can be turned to gold.
3 Freshman military training brings tears, Changan loves to eat smoked sausage.
4 A thousand miles of predestined marriage hangs by a thread, whether it's good or bad all depends on fate.
5 My idol is the absolute best, the idol chose me to be their partner.
6 The boss behind the scenes is here, doing whatever they want without logic.
7 Ghost Festival inspiration comes late, helplessly put here.
8 Official advancement and wealth cost a child's life, a good son leaps like a carp over the dragon gate.
9 A trip to the plastic surgery clinic, all the fat is shaken off.
11 Who in the Human World can resist a beauty? Run out of roman numerals, use numbers instead.
11 Turtles may live long, but still dread the end, the characters fear a 404.
12 The local zombie looks handsome, cries out adorably when opening its mouth.
13 One dance captures the city, the beauty of the past fades away.
There's a lot more, too tired to write the summary...
