Chen Yu transmigrates to Blue Star and becomes a caregiver at a nursing home, but he soon realizes something is off about the place.
There is Grandpa Xiao Huohuo, who keeps shouting, "Don't look down on the poor just because they're old," and often whispers to a ring.
Then there's Grandpa Tang, who's old enough to have a full head of blue hair and spends every day clutching his Mischievous Bunny pillow, crying and calling for Xiao Wu.
And Grandpa Xu Kun, an old man with white hair who likes to part it down the middle and wear overalls. Every afternoon at three thirty, he has to go play basketball.
Then there's Grandpa Li Baisui, who insists on taking two cleavers with him even to the bathroom and demands a ninety-eight percent chance of winning in everything!
Chen Yu initially thinks they are just a bunch of ordinary old men with a bit of a chuunibyou streak. Then one day, he discovers that they're all cultivators who can soar through the sky, burrow through the earth, and slay gods!
Chen Yu's entire worldview and sense of decency shatter on the spot!
