Chapter 19

Chu Xia, fourth prince, son of imperial concubine, has lower status. But due to his low-profile nature, he didn't incite the others' jealousy, and so he had a very good relationship with all the princes. 
Chen gives his mom the Facial Rejuvenation Elixir to make her look younger.
Ever since his father had been stationed at the border, he seemed to recall that his mother had never once visited the family on her side. Her own family was already in a miserable situation, so his mother had never tried to go there to beg for help.
Long Chen held her hand and said, "Mom, your son is now an alchemist. Our hard days are over, so don't think about such sad things."
After accompanying his mother for some more time and seeing her mood gradually relax, Long Chen went to the alchemist guild.
