As an ordinary college student in the 21st century, Gongliang Yixuan planned to jump over the wall and go outside to have some extracurricular life, but he didn't expect that he would close and open his eyes and travel through time! I traveled alone to the second year after the end of the world, and the place I traveled to was still an inaccessible forest. Fortunately, Yixuan got a magical system to build a base, build power, and save the world. Everything is no longer just a dream! The end of the world is full of dangers, but there is still hope in life!
