I enjoyed the story, but there were moments when I didn't like the main character, which is why I gave it 4 stars.
The male lead (ML) is Qianxian (from the machine translation), and the four sons are the children of the ML and the female lead (MF). In their past life, the ML betrayed the MF. The ML was the third prince or something similar, while the MF was the leader of a highly sacred ground filled with herbs and treasures. Royalty and others plotted to seize the land that the MF owned, and the ML was one of their pawns.
The ML sent a letter to the royalty with incorrect information about the entrance to the sacred ground, intending to trap them with false directions. However, someone altered the letter, allowing people to enter the sacred ground despite the ML's plan. The MF discovered what happened and hated the ML, leading to a classic misunderstanding trope.
After the conflict, the main character (MC) learned the truth but didn't know where the ML was. Using his blood and her blood, they created four fruits, which turned into their sons.
I'm tired, so I'll keep it short. The MF did not reincarnate as a character in a book; it was really her, but due to some fragmented memories, she forgot about her past. She suffered in her first life because it had to happen to stabilize the world. When she returned (at the start of the novel), the world was already stabilized.
, the story was good, but I particularly liked the reaction of the fourth son when she found him. I think it was the most grounded and realistic.
