His Majesty the King Is the Watchdog of the World's Miracle Doctors

Rejuvenation, immortality, and resurrection are no longer human dreams. Lin Jian, the best doctor in the world, found three magical herbs that were on the verge of extinction. He tried to take them himself, and a miracle happened... The miracle doctor Lin Jian himself died once, but he miraculously came back to life. He transformed himself in his twenties into an eighty-year-old man, and then returned to youth again, switching freely. All of this comes from those three mysterious herbs. Finding mysterious herbs is even more difficult than reaching the sky. Lin Jian, the miracle doctor, tried to cultivate three mysterious herbs by himself, but the survival rate was extremely low and it was hard to find them.
