They're All Dead and I'm the Only One Left

The four directions are called the universe, which has been called the universe throughout the ages. The place where you and I live is the beginning and even the infinite space. The long river of time is all the universe. The three-dimensional parallel space is divided into nine. They parallel each other but do not interfere with each other. Until the disaster comes, the black disaster strikes, the space barrier is broken, the nine time and space collide in disorder, and all life on the earth is in ruins. Where should I go?
