In ancient times, the war between gods and demons spread to the six realms. In the end, the gods relied on the power of the divine weapon "Lone Star Sword" to narrowly defeat the demons and seal the gate to the demon world. The remnants of the demon clan are scattered in all directions, suffering from bullying, and the demon god is nowhere to be found. After this battle, the Gods also lost their troops and suffered heavy casualties. The two gods who were about to succeed the emperor and empress had exhausted their divine power and were unable to return to the top of the clouds. They had to use their mortal bodies to nurse their souls back to health with the help of the other gods. After that, the world was at peace, and the gods and demons lived in peace with each other.
Five hundred years later, in the town of Juan'er, a boy and girl met. At that time, the boy had no past and no name, so she named him Mu Fan. Mu is her Mu, ordinary people. But just when the two met to get married, the girl left without saying goodbye. That year, in order to meet her again, he searched the three thousand worlds and came to Kunlun, the world's number one sect of cultivating immortals. He wanted to ask for the "Mirror of Universe", the magical artifact of the immortal family, but he made some friends by mistake. After the "Kunlun Question", they were ordered to go down the mountain together, thus uncovering the intrigues between famous families, the struggle for power inside and outside the royal family, and the secret past of the ancient war between gods and demons...
Intention: Lone stars are never alone, only love lasts forever.
