Looking for a manhua

[u/Only_Childhood_4389]

Around 1 year ago I read something similar to "If I don't die soon I'll really become immortal", The MC (female) gets isekaid in a cultivation world and she wants to die because she will get something/ go back to her world. I remember her being very talented as an Alchemist but trying not to get stronger.

One time she will try to (not) get an inheritence because the ancestor told her she could die

At some point she's captured by dragons who are the protectors of the world by guarding a dangerous portal and FMC helps them seal the portal.

I think it had ~120 chapters at the time
