Archipelago Survival Battle

In the new galaxy of the 81st Sun Epoch, when the sun had perished, humans finally developed a small wormhole, also known as a time machine, on the new Earth-2. However, they remembered the fear of being dominated by unknown civilizations in the Stone Age, so they prepared to organize an event: travel back to the Stone Age and engage in a survival competition. The country that wins will have the manufacturing and ownership of the wormhole time machine. This novel and its characters are purely fictitious.
