My Identity as an Immortal Is Changeable

I am an immortal who has lost his memory. In order to search for memories, I began to search for history. In the era of demons, I was the demon master worshiped by all demons. In the age of gods, I was the great deity who looked down on the world and suppressed all sentient beings. In the Buddha's time, I was the trinity of the future, present, and past Buddhas. My name is Jiang Qing, an immortal who came from history to the present world.
