Travels in Another World

"You may not believe it, but I have traveled through time." My name is Cheng Qiming. I gave up my studies and entered the society prematurely, and finally became an ordinary social worker. When I woke up, I traveled to a different world that I had dreamed of, but I was not in a famous family, nor did I appear in some mysterious cave; I didn't have any 'system' on my body, nor did I have a 'portable grandpa', and I didn't even see an NPC that gave me quests. "Then why did I travel through time? To travel?" I glanced at the book on the table. Its title was: Around the World Edition 2.0.
