Tong, a sinner who was suffering endless torment in hell because of his mistake he had done in his previous life, was giving other chance to redeem himself by the devil.

Qin Xiaoguo was a successful chef working in the future era. A turn of fate brought her to the past, into a time of famine and uncertainty. Waking up one day, Qin Xiaoguo found herself face to face with a boy who acknowledged her as his mother.

Having transmigrated from the year 3024 to 42 BC, Qin Xiaoguo had traveled across a three-millennium time leap to the past. She was transported to a destitute place, and also became mother to a hungry, skinny boy at the same time.

Her only comfort to her new-found circumstances was a spatial ring that allowed her to transmigrate—giving her free access to food and other belongings from a different era.

After years of raising her son singlehandedly, Qin Xiaoguo had a surprise visitor at her door. It was a man claiming to be her husband, requesting to stay the night. Out of confusion and pity, Qin Xiaoguo let the self-proclaimed father of her child into the house.
