Two alien elves use twenty-four solar terms to measure the sweetness of the earth. The green-haired cybernetic elf from Venus thinks that Earth's food is primitive biological weapons; the golden-haired healing elf from Mars is so sweet that he doubts his life after a bowl of loquat. From red bayberry to small loquat, they use solar terms as a map and taste buds as a navigation, and plunge into the oldest rhythm of life on earth. Diary body, light healing, each chapter has a solar term + a kind of food + a period of inner crit of the elf.
