Wang Yi gets a key, opening a door in 2022 will lead to 1982, and opening a door in 1982 will return to 2022.
Two very different great eras appeared before him:
Abundant dietary protection, developed industrial products, miraculous medicines, and explosive information, this is 2022.
Simple folk customs, rich wild resources, scattered antiques, and treasures of the age, this is 1982.
Traveling between these two eras, Wang Yi didn’t think much of it, he just wanted to live a good life.
