This plot described how Lin Daiyu (formerly known as Crimson Pearl Immortal Grass) owed Jia Baoyu's previous life's Shenying attendant the grace of irrigation, so she repaid it with a lifetime of tears. Then, in her new life, she used her memories from her previous life and modern medical knowledge to cure her brother. She also got rid of the fate of an early death and practiced a profound and peerless martial arts. However, she still could not escape the fate of the Jia family and was even involved in the whirlpool of the royal family's struggle. I hope my recommendation can help you find a novel that you're interested in. Muah ~
