A food deliveryman gets into a traffic accident and transmigrates into the body of a puppet emperor of the Great Yong Dynasty! Equipped with three powerful advantages—medical graduate-level emergency treatment skills, sanda fighting techniques, and the extreme reflexes he developed as a deliveryman—he awakens at the very moment the vicious empress publicly humiliates his beloved. Using the wisdom of an ordinary man, he breaks through impossible situations, tears apart treacherous consorts, confronts powerful ministers head-on, tames a tiger with his bare hands, and risks his life to test medicine and save the people. From a puppet controlled by others, he rises to become an emperor whose might shakes the world and whose name will be remembered for generations. Just when peace has finally come and his wife and children are by his side, he suddenly awakens in a hospital. It turns out everything was an illusion caused by the car accident, yet the love and hatred he experienced in his dream unexpectedly reunite with him in reality.
