  On a seemingly ordinary summer night, a catastrophe brewing for hundreds of millions of years reaches the Earth from deep space. The radiation from the supernova explosion irreversibly irradiates everyone over the age of 13, leaving them with only a few months to live. Children under 13 years old can recover. That means that all humans over thirteen in the world will die, and the Earth will become a world with only children.
  
  It is a society the world has never seen before; adults are supposed to teach their children life skills in the shortest possible time, such as running a country, commanding an army, etc. The adults also leave their children the best gift, the Chinese Quantum, a super quantum computer, which will help the children go through a dark age that follows. In the early days of the supernova era, the world of children becomes the last continuation of the world of adults. After several months of seemingly smooth operation, it finally gets out of control.

First, they want to build a candy world, where the building shell is edible chocolate; They have created the maximal online games. Because all children are participants, online community organizations are even equipped to compete with the state power; In the end, they found that the most exciting game is war.
