The Void Villager (OP, Naive, and Clever)

In the Void between the Realms, there's a mysterious village. When Immortals and Gods travel between different realms, they stay there to rest. Lei Yuan is just a boy born in this strange place. Harmony Goddess taught him music, Crimson Wargod trained him in martial arts, and Dan God discussed the Dao of Alchemy with him. Too bad no one taught Lei any common sense... One day, Lei fell in love with a young 300-years-old girl. Known as System Goddess, Jessica was the person closest to his age among those he knew. The stories of her home from the previous life - a strange place named Earth - intrigued him no less than the myths of her ascendance to Godhood. When she left the village to continue her travels, Lei made the mistake of asking for love advice from Pleasure Emperor himself... Now 16 years old, Lei "secretly" escapes the village to become the man worthy of his crush. Then, he'll find her and confess his feelings. In the meantime, he'll travel the vast universe and turn into a legendary cultivator. Is the outside world ready for The Void Villager? *** The story features some gamelit elements. MC is innocent and naive, he's also OP, but "super genius" type of OP, not "one-punch man" OP. The MC is similar to the one in Cultivation Online and the story is going to have a similar flow. So if you like CO, then check this story out. Also, there's a harem, but it's cute, slow, and I have no plans for adult scenes. The story is also posted on Royalroad and scribblehub.
