We are students in the human world, and we are workers in the underworld. My name is Yan Yuyan, the newly appointed Lord of Hell, who was thrown into the underworld school by the sealed power to work as an NPC. During the day, I learned how to use my grievances, and at night, I hid from the underworld and was hunted down. There are still a bunch of barrages in my mind that are broadcasting live every day as I run away. There are people in the world waiting for me to come home for dinner, and there are accounts in the underworld waiting for me to go back and settle them. It's too difficult for me to run in both directions.
Purpose: Only by guarding those who deserve to be guarded in the realms of Yin and Yang will our lives be considered not in vain.
