I've Been Walking for a Long Time, Do You Think This Is for Survival?

Three years later. The survival game has arrived. Humanity will struggle to survive in an unknown world. But no one knows. Before the game begins, a person who does not belong to any world has already embarked on a journey in advance. Yang Mo. His past does not exist in the world, but his future remains. At first, he just wanted to find a way to survive. Later, he discovered that his mission had long transcended personal survival. Travel through different worlds. Explore unknown civilizations. Looking for the last hope left by mankind. However, the problems that trouble the savior often do not lie in these, but... "How can I pretend to be a normal person while saving the world?" Or "How can I explain to my new partners in each world that I am really not here to cheat on food and drink." Very urgent, waiting online!
