Starting with the Rise of Paradise

Lei Xiao lost his memory for no apparent reason.

It seems he's forgotten many important things.

Then he discovers a whole string of new problems:

“Why are my stats abnormal?”

“Why does the Paradise keep disconnecting?”

“What do I do if antivirus software starts hunting me the moment I enter a plane world?”

“Can anyone answer me?”

“Waiting online. This is pretty urgent...”
