Traveling Between Dimensions

"Hello everyone, I am the protagonist of this work. My name is Bai Yumo. I am not a human. Generally speaking, I don't know what species I am. I chose my name myself. In order to integrate into this world, I existed before the birth of the world. It seems that species classification has not started at that time, so who am I? Ahem, back to the topic. Today is a day in 20XX , I don't know how long I have been alive. Just this morning, I just woke up from my comfortable big bed. To be precise, I should have been woken up, because something called a dimensional chat group suddenly appeared in my mind. I have never seen anything like this in my life. But the people in it are so nice to talk to. I really like this communication group. " This novel and its characters are purely fictitious.
