Awakening in a dilapidated earthen house, Zhang Erniu discovers that he has returned to the time when his wife was six months pregnant. His family is now desperately poor. Overwhelmed by crushing guilt and the joy of being reunited with what he had lost, Zhang Erniu vows never to fail his wife again in this life. To ease Shen Shuxian's fear, he takes clumsy but sincere actions, such as catching crayfish in the river and preparing meals, allowing her to see the possibility of change. Using his knowledge of the future, he earns his first fortune by selling the overlooked crayfish and astutely spots a business opportunity at the Yiwànxiāng Noodle House, establishing a long-term supply partnership.
