In her last life, Su Wan watched her brother Su Chen being used as a "training tool" for surgery by her beloved Gu Yan and her childhood sweetheart Lin Weiwei, and was even forced to sign a letter of understanding by threatening to stop treatment.
After she compromised, Gu Yan went to comfort the "frightened" Lin Weiwei, leaving her to watch her brother die in pain.
Desperate, she slit her wrists in front of the tomb and entered the world of immortality.
In order to resurrect her brother, she struggled in the world of immortality for three hundred years, from foundation building to Mahayana, and finally faced the thunder catastrophe of ascension - but the ninth thunder catastrophe did not allow her to become an immortal, but instead knocked her back to modern times. She happened to land in the ward where Gu Yan forced her to sign, and her brother was still alive!
She first used the Time Stop Technique to test that it was not the inner demon state, and then used her spiritual consciousness to detect Lin Weiwei gloating in the parking lot, and even found out the harmful ingredients in her brother's medicine.
After confirming that she had truly returned, she took out the Nine-Turn Resurrection Pill that had taken three hundred years to refine from her storage ring and fed it to her brother. Seeing that his face turned red, she used a harmless slumber spell to put him to sleep.
Turning to look at the still Gu Yan, Su Wan only had a cold look in her eyes: the debt from the previous life, three hundred years of suffering, in this life, she must protect her brother well, and then let Gu Yan and Lin Weiwei repay the principal with interest!
