[The end of the world + technology tree + civilization restart + Dr. Milk Frog]
After midnight, the world forgets a key piece of knowledge every day.
On the first day, humans forgot how to send electricity.
The city plunges into darkness and the hospital's backup power supply begins counting down.
In ninety-nine days, modern civilization will completely collapse.
Just when everyone was at their wits' end, a 90-centimeter-tall Dr. Milk Frog wearing round glasses woke up from an abandoned kindergarten.
He can understand out-of-control machines, and he also knows how to recreate things that humans need from a pile of scrap metal.
Dismantling toys and repairing power grids;
Light up cities and rebuild industries;
Build starships and find the next path to civilization.
As long as he is given enough materials and time, Naibo can relight the technology tree bit by bit.
But every time he forcefully saves civilization, he loses a piece of his memory.
Until one day, he discovered that what he was forgetting was the truth behind this civilizational disaster...
