Prodigiously Amazing Weaponsmith

Who caused MC death in the first life?
Will she learn alchemy? 

Can someone give me spoiler from ch 1902 - 2021 please
I know it's a bad habit, but can't help it
And this chapter I don't know why, to lazy to read it and want to skip it please make it simple and thanks 

Eh just realize I read MTL until chapter 1830 and so far haven't her dad yet 

What happened to MC's and ML's forces when they died? Was the one who betrayed MC her martial sister? 

Fck so far away 

I remember that HYL dreams of a time when MCY proposes her in their last life. Which chapter was it? 

thank you!!!!!!!!!! 

The Male lead (past life) and Dr. Liu are bestfriend. Dr. Liu already like the MC but Male Lead told him that he likes the MC so he gave her up.

Then Dr. Liu met the MC's reincarnation and fell for her again. He doesn't know that the MC is the reincarnated self of his first love. He doesn't want to give his love this time around so he took the MC away and prevented her from recovering her memories.
