Review Detail of Novel_Dao781 in Doomsday: I Obtained A Fallen Angel Pet At The Start Of The Game

From chapter 156 to chapter 157 and from chapters 160 to 161, there is a strange disconnect because why did he get transported there? How did he get transported there? Why is the chapter after he goes into the dilapidated building he somehow is in some kind of life or death arena with a level of 40+, and it shows through the dialogue that he is in some shop and he has his own room fought with the lizard man before well when did all this happen between 160-161? but he entered the dilapidated building in 160, and then bam, he is in some shop/life or death arena in 161. Why is this so?
