I Just Want to Lie Down in Hell

I was working as a salted fish in the underworld, sweeping across the three realms with my breath, but my mortal enemy, the Imperial Master, was reborn to love me. This imperial mausoleum connects the human dynasty to the underworld, and I am the tombkeeper trapped in the middle. I thought I would be with monsters and monsters for the rest of my life, but I didn't expect that the "lying flat system" descended from the sky, and I could ascend to a higher level even while sleeping! In order to investigate the cause of death of the empress in the previous life, I made a contract with Rong Ci, the number one Feng Shui master in the dynasty. But this man who was rumored to be a decisive killer looked at me more and more wrongly. He not only tempted me with delicious food, but also always called me another name in my dreams. It wasn't until Evil Lord Netherworld broke the seal that I discovered that he was actually my biggest enemy in my previous life.
