Chen Qiu had transmigrated to an Immortal World, where in this world of immortals— there were Heavenly Dao Decrees, a panel-like “Heavenly Pride Leaderboard,” and numerous entries. ... Every cultivator, upon breaking through a Great Realm, could obtain an entry. Different entries combined to define the cultivator’s limits and directions for development. Some cultivators relied on the entry combination of “Nine Ox Power” + “Hundred Percent Accuracy” + “Ignore Barrier” to marry into the Dragon Clan and became the greatest Beast Master in history. Others relied on the entry combination of “Nonsensical Babble” + “Deceive the Junior, Fool the Senior” + “Martyr’s Command,” becoming the greatest State Preceptor in history. Meanwhile, Chen Qiu’s first entry, “Rise Through the Ranks,” allowed him to choose one out of three random entries each time he broke through a small realm. From then on... Various entry fusion techniques, astonishing the human world! ... When everyone in this world had a golden finger, it all came down to whose destiny was tougher!

Wang Yi gets a key, opening a door in 2022 will lead to 1982, and opening a door in 1982 will return to 2022.

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.
