Xiaoyi is a "vegetarian baby", which was originally a cool and healthy thing, but recently, a series of strange things happened to him: his skin always seemed like a swarm of ants crawling, itching so much that he couldn't sleep; in class, his attention was like a kite with a broken string, and he couldn't concentrate. One day, the most amazing thing happened! His consciousness, like a spaceship shrinking, entered his own body with a "whoosh"! What he saw before his eyes were red blood cells packed with oxygen running along the highway of blood vessels; white blood cell warriors in white armor patrolling carefully; and platelets as cute as round pancakes, busy repairing the road... It turns out that there are so many hardworking and cute little guys living in our bodies! Xiaoyi soon discovered that this supposedly orderly universe was being shrouded in a dark crisis called "malnutrition." The itchy skin and lack of concentration he encountered were just the beginning of the crisis. What's worse is that this crisis has quietly spread like a vine to his entire family: his mother who diets desperately to lose weight, but always fails and has a sallow face; his grandfather whose memory is getting worse and worse, and sometimes even forgets the way home; his good brother A Zhuang who sprained his foot while playing badminton together, but couldn't recover for a long time... The body universe of each of them has a dangerous red light on! Just when Xiaoyi was most confused, an ancient secret was revealed - he, Xiaoyi, turned out to be the only descendant of the ancient "Nutritional Guardian" family!
