Alexander was the greatest tyrant in history. His cruel, brutal and vicious reign struck fear in his enemies and allies alike. But that all ended when he was betrayed by his own people and beheaded by his archrival. As Alexander’s consciousness faded away all he could think of is all the faults he made, how he could have avoided them, how unlucky he had been, and his wrath and unwillingness to die at the hands of the man he hated most!

Mu Liang knows that there is something mysterious going on around her. She got a mystifying background and perplexing capabilities. But he doesn’t care about who she was in the past and why they keep attacking her. All he can think of loving her, cherishing her, locking her up so that she will never return to her past.

Li Muyang had transmigrated, and the good news was that he had a system. The bad news was that this system could only be used to play games. Oh well, if it’s playing games, then so be it. It’s better than having nothing. In the game, he was powerful and mysterious, causing the extraordinary fairies to be shaken to their core. Since it’s just a game, there’s no problem in aiming for the full compendium route, right? It wasn’t until one day that the fairies from the game showed up at his door that Li Muyang was truly startled. What was supposed to be just a game, how did it become real? “So... listen to my excuse!” I was really just playing a game!!
