A journey of redemption that begins with a slave girl

As a veteran gamer, Nan Huishou was just about to play the integrated package he had bought when he was killed by an exploding computer.

Fortunately, he was chosen by the system. As long as he traveled through different worlds and completed enough tasks, he would be able to return home with a lot of wealth and abilities.

He considered himself an advanced player, but was dumbfounded after seeing these mission worlds.

What's the deal with the slave girl, and what the hell is the dog princess?
