I Started Badly, but I Fought My Way Through Another World

Others who traveled through time were either Gold Finger or Long Aotian, but it was better for Duan Senran to travel through time with a severely injured body! System? Yes, but it is still a broken version and needs to be upgraded and unlocked by yourself! But it's not all bad news. After all, the weapons were brought with them... The rifle was blown to pieces again! Everyone said that Duan Senran was dead and hopeless! But he did not believe in evil. Even though he had done many evil things as a Blackwater mercenary in his previous life, it was natural for him to die, but he wanted to live. He wants to carve out his own piece of heaven in this alien world!
