Jun An and Rong Ruo are mortal enemies. Rong Ruoxianjun is a well-known modest gentleman in the fairy world, but when he meets Jun An, he seems to have changed his appearance. He has a bad attitude, harsh words, and has no idea what compassion is. So when everyone collectively praises Rong Ruoxianjun for being elegant and gentle, Jun An thinks that people in the fairy world are masochists.
Until one day, the fairy grass that Jun An raised injured a grass. It was said that the fairy grass was an ancient sacred grass, and it was the only one left in the world. What made Jun An even more worried was that the grass belonged to Rong Ruoxianjun. Rong Ruoxianjun was a famous calf protector in the immortal world, and he was not on the same page with him. In the sympathetic eyes of the immortals Xian'e, Jun An's master and servant lived a life of being hunted down. The fairy world is also in chaos, Fairy Chang'e's laurel tree has fallen, Yue Lao's red thread is messed up, and even the love tokens of the Emperor and Queen of Heaven are not immune. The Emperor of Heaven couldn't bear it anymore and waved his hand, saying: "When will we be in peace and when will we return?" The two of them entered the underworld with the determination never to return to the fairy world.
From then on, the people of the underworld lived a life of fear that their homes would be demolished.
