Savage: Cave Sky

In 2065, hundreds of thousands of geniuses and scientists voluntarily entered a closed area called "Dongtian". In "Dongtian", regardless of age, major or ability, everyone respects each other as "teacher". It was a world without the concept of money, only learning and research. In 2115, after 50 years of closed development, the technology in "Dongtian" developed explosively. The human beings in the "Dongtian" have undergone brain evolution, so some people call themselves "Jinren", while the billions of humans outside the "Dongtian" are called "savages". Some "enterers" attempted to reopen the "Dongtian" on the 50th anniversary of its establishment, with the purpose of clearing out the billions of "savages" outside the "Dongtian". On this day, all mysteries about the cave will be solved.
