Start from Douluo and Go Down the River

Xiaosi forgot when he had been living under the control of the light ball. He only knew that the light ball, like the main god's space, transported him to various novel worlds and completed various tasks. I was lazy and wanted to take a vacation for myself, so I chose Tang San, who seemed to be very popular, as my teammate. Who would have thought that I hadn't been free for two days yet... (The title of the book is just to gain popularity. I read it in junior high school on Douluo Continent and have long forgotten it. As for you asking me to read and write the plot of Douluo now... I will definitely write it if it becomes popular.)
