What Do You Do When You Fall from Being a Grandfather’s Generation to a Grandson’s?

[Douluo Dalu Fanfiction, Ensemble Cast, Reborn, Grandfather Generation, Playing the Fool While Hiding One's Strength]

A note on the backstory: Reposting an old story.

Dugu Bo, Yu Yuanzhen, Yue Guan, Gui Mei, Gu Rong, Chen Xin, and other Titled Douluo from the grandfather generation, along with Ning Fengzhi, sect master of the Seven Treasure Glazed Tile Sect, were originally elders in the divine realm. Their descent into the mortal world and the various trials they endured were all part of their tribulations. But because Tang San was a transmigrator, he disrupted the original world's destiny and caused their tribulations to fail. To ensure their second attempt would succeed, the Creator God turned the seven elders into young men and sent them back to the time when Tang San had just awakened his Martial Soul.

But although it seems they simply returned to the past, their younger selves and a crowd of clueless onlookers mistake them for their younger selves' illegitimate children.

How are a bunch of grandfathers who are Titled Douluo supposed to cope with becoming promising young Soul Masters in the same generation as their own grandchildren? Asking online, urgent!

Note: This was written back when I was in elementary school, so the prose is rough and there are lots of headcanons. Main couples: Ghost-Chrysanthemum, Sword-Bone, Dragon-Snake; Ning Fengzhi's pairing is undecided. Any OOC is on me; the characters belong to the original work. Their appearances are based on the manga. If you come across a plot that seems especially familiar or a setup that resembles someone else's story, don't doubt it: I was the first to write this setup and this trope. (Yes, I got scared off by plagiarism and comparison charts back then, but I really was the original author.)
