Crime Lord of Shichuan: about a guy who has a hero type heart gets Tangled with criminals and has to somehow survive and save his family.(I don't think it's available in English but it's good if you can find it.)
My House of Horror: if you can handle immersive horror progression stories than you will be fine. ( I never managed to read after 500 chapter.)
I am Not the Demon God's Lacky: Doesn't fit your weak to strong mc part but mc is not the focus of the story other characters are, although it's ending always disturbed me.
Skeleton Prince is in Bad Mood or something can't really remember its name well but is a story about a skeleton's adventure through dangers places in hopes of saving his master, it was slice of life i think too much focus on struggle self improvement and stuff.
Clown Prince of Gotham: Yes it's a FanFic, could be published in different titles like I am the joker, Harley is trying to kill me or Batman is just too persistent.
I know what you are thinking but it's perfect for the genre weak to strong and well weak against strong. The guy basically has the world after him and somehow has to survive and gets stronger (painfully) after each encounter.
Rock falls everyone dies: on royalroad, complete, about a journey of a rock that gains minor sentience and has to go down the mountain. It's litrpg but fits.
Throne of Magic Arcana by Cuttlefish: pretty good if yer interested in scientific magic. Weak to strong, good worldbuilding, cool visuals (in text obviously ?)
The Protagonists Are Murdered by Me: Cold and Ruthless protagonist. Fast paced(very), shares some themes to Solo Levelling especially it's end game worldbuilding.
The Villain Wants To Live: Cool start not very powerful centric really it's more about the state and the legend of the world progression than power progression. But "mc" does start of as weak and gets strong.
I'm Spider, So What? : It's has a webnovel and light novel version both try to read webnovel one it has much more better world building but the light novel is more organised.
