MC Interior: Invincible Cube Man

In a world that is rebuilding at the end of the world and waiting to be renovated, the alien beasts and zombies have not yet been completely eliminated, but humans are already proudly on top of the world! The level of science and technology has been restored from loss to even better than before. Business giants divide food, electricity, and medical care, and giant companies rule the earth... And the city that hangs high in the sky and uses the name of the academy to cultivate new era superpowers, no matter how humble it is, is a well-deserved world leader. Zhou Yan traveled through time and was about to enter the Super Power Academy and become a transcendent superpower, but... Everything has a price!
