After Scumming the Black Immortal Lord

It is said that before the Immortal Lord succeeded to the throne, there was an unknown love affair. The Immortal Lord asked for it but could not get it, so he turned black and was demoted to the mortal world by the Heavenly Lord. However, he did not want to be harmed by that person again. Song Nuo ran around and finally got the task of arranging a relationship for the immortal king. He wanted to take this opportunity to have fun in the mortal world, but he couldn't get himself involved... Many years later, Song Nuo looked at the Immortal Lord who came to the door with a sword, and felt panic in his heart. Didn't he say that the Immortal Lord would not remember those things in the mortal world...
