The Simple Life of Killing Demons - Chapter 22Book 12:

The future unfolded on a magnificent scale into the Interstellar Age. Humanity finally solved the space warp technology, but when humanity transported themselves into the other end, they discovered that place neither had a past nor future, nor was there any land under the starry skies……

People all say that the fourth daughter of the Marquis of Jing’an is really lucky. She is favored in the palace, has heirs and has a good family background. That is really a great thing! In fact, Shen Chuliu himself didn’t know how he got to this point.

It was like this at first. The concubine next to her was playing the piano and dancing. Shen Chuliu said that I was not a performer.

The concubine next to her was writing poems and painting, and Shen Chuliu said that I didn’t want to take the imperial examination. People laughed at her and said she was not favored. She smiled slightly and said, “I have a family background.”

The emperor really has no choice. If the concubine doesn’t come to please her, he still has to see her! Who said someone’s mother’s family is really awesome? Shen Chuliu really didn’t care. Those bastard relatives liked him so much that he started to let himself go as soon as he entered the palace.

It feels good to let go for a while, and it feels good to keep letting go. As a human being, the most important thing is to be comfortable. If you are too frustrated, even the emperor will not be able to use it!
