That day, every human being in the world turned to stone.
Three thousand years later, a player from another world, [Shishen Yue], logs into the full-dive game Stone Age New. He disconnects from the internet to play the single-player version, then can't find the exit button.
[Ultimate Quest: Revive all of humanity]
Who? Me?
Wrapped in his starter animal-hide outfit and holding his starter pickaxe, Shishen Yue stands amid a vast primeval forest and falls into deep thought.
[Main Quest: Revive one companion 0/1]
Shishen Yue sighs. Fine, he'll revive someone nearby first. Hopefully it'll be some brawny, simple-minded musclehead.
After being released from petrification, Xia Youjie looks at the cold-faced boy in front of him, barely covered in animal hides. He looks at himself, stark naked, then at the endless primeval forest, and finally falls into deep thought. "..."
Xia You: "You damned monkeys. Just watch, I'm going to kill every non-sorcerer in the world."
Shishen Yue: "There are only two humans left in the world. Are you sure you want to? ...Tsk, why did I get an edgelord? Fine, as long as it doesn't get in the way of work."
[Main Quest: Revive five companions 1/5]
Shishen Yue: "Who should I revive this time? I need someone handy, a craftsman type. Got anyone in mind?"
Xia You: "I recommend my best friend."
Shishen Yue: "What can he do?"
Xia You: "He... He knows advanced mathematics."
Shishen Yue: "Advanced math? That might have to wait ten years. Let's see whose stats are a little higher. This one, then."
And so Dazai opens his eyes and finds himself face-to-face with two naked men, standing in a primeval forest with barely enough clothes to cover themselves.
Dazai: "." A few seconds later, he closes his eyes again.
The once-great prodigies of the original world have been enthusiastically put to work by the gentle scientist Shishen Yue.
