Mystic Master

My name is Li Haoran, 24 years old, an ordinary real estate salesperson in Jiangcheng. After two years in the industry, I became the regional sales champion thanks to my glib tongue. I thought my biggest worry in life would be how to sell houses. Six months ago, I sold a second-hand house in the old city. The client moved in and came back within half a month, saying they could hear voices in the walls at night and demanding a refund. I didn't believe in superstitions at all and swore the house was fine. The client insisted I stay there for a few days to prove it. I thought, what could happen in three days? But on the first night, I heard footsteps in the living room. On the second night, I found a row of wet footprints on the floor leading to the wardrobe in the master bedroom. On the third night, I smashed open the hollow wall behind the wardrobe and found a skeleton hidden inside. — Description from novelcodex.org
