Mythology Mortician

My name is Yu Feng, after I was attacked by Universiade on the 18th floor. I traveled to another world with my coffin, but during the journey, a little accident happened... My coffin got a little dirt on it somewhere. On the day of the crossing, the soil was only the size of a thumb. But on the second day of time travel, the soil actually covered half of the coffin! I panicked a little, so I dug a hole and buried my coffin! But... In the early morning of the third day, I felt a sharp pain. I quickly took off my clothes, and when I looked down, I saw a palm-sized patch of dirt growing on the skin on my chest.
