So heres the thing a while ago I was reading this novel in which the mc was a prince(i stopped because there was too few chapters) but was framed by his stepmother of raping her which lead to a big scandal and him being crippled and banished from the kingdom. As he was being escorted away a monster(i think it was a snake) tries to assasinate him but an immortal(idk) saves him and mc beggeds to be his disciple.. He was declined but was brought to the immortals school.. i can still provide more info if this is not enoug.
Swallowing the Heavens, used to be Devouring The Heavens, but the name is the same with pan's translated novel so it was changed
