Who Changed My Three Kingdoms?

Luo Xuan transmigrates into the world of the Three Kingdoms. He'd planned to lie drunk with beauties in his arms and wake up holding power over the realm! But to his surprise, as soon as he arrives, he's forced to merge with the Heavenly Dao. Only then does he learn that this world is under invasion from the myriad heavens, and the Heavenly Dao brought him here to set the world right. From then on, Luo Xuan begins his career as a cosmic handyman, patching up the world! What's more, he thinks everyone seems suspicious. Hmm, there's something wrong with Hua Xiong. How could he fight Guan Yu for fifty rounds? Has Liu Bei been possessed? Why doesn't he seem nearly as ruthless and calculating as he should be?
