Everyone Traveled Through the Primitive World, and I Became Stronger in Survival

Not invincible, not hydrological. All the people of Blue Star traveled to a primitive continent. In order to survive, in a world without law, people burned, killed and looted. The male Zhang Yun relied on his mercenary experience and had to become stronger step by step in the killing in order to make himself and the people around him survive better. Your food? Your weapon? No, no, no, mine, all mine! If you dare to bully me, then there is no need for you to exist. While improving his own living conditions, Zhang Yun was also exploring the reasons why the Blue Star people traveled through time. As he went deeper, Zhang Yun discovered that all of this was like a conspiracy, and there was always an invisible big hand controlling everything!
