Transmigrated into a Book as the Villain's Live-In Son-in-Law

Modern web novelist Su Yan dies suddenly after staying up all night writing, then transmigrates into his unfinished xianxia novel, The Son-in-Law of the Mystic Heavens, as the villainous son-in-law who goes head-to-head with the protagonist, Lu Chenzhou. In the original book, Su Yan was called "Third Young Master Su," and readers cursed him for colluding with the demonic cult and betraying his wife, Su Qingxue. Armed with an "Author Panel" that lets him inspect character stats and plot points and alter minor events at the cost of his fortune, he must turn his fate around before the original story collapses, rewriting the path of "humiliated son-in-law -> colludes with foreign enemies -> dies and is erased from the Dao" while uncovering the truth behind the mysterious being controlling the novel's world.
