Tangshan, who was delivering a courier, was hit by a Mercedes-Benz in order to save someone. He traveled back in time to a young man with the same name as him in 1974. He had three younger siblings and a blood-sucking grandma and uncle, who squeezed the four Tangshan brothers and sisters at any time. Although this era is very hard, there are endless treasures in the vast mountains of Yunling. Tangshan can raise cute pets in this era and lead a good life with his younger siblings.
