Immortal? I'm Just a Blacksmith

Wang Goucheng, a blacksmith apprentice in Qingshi Town, has a simple life plan that can be seen with the naked eye: save enough money to marry Erya from a neighboring village, guard the blacksmith shop and swing hammers for the rest of his life, and raise three children to pass on the blacksmithing skills. But a thunderstorm hitting the back mountain shattered this ordinary life into pieces - he bumped into Lin Yu who had fallen from the "Earth". Lin Yu was dressed in flashy clothes, with strange symbols printed on his chest and a glowing cube in his hand. He claimed to be a time traveler with the "strongest immortal cultivation system". However, he broke his leg and the system was damaged. Only the basic panel was left. He couldn't even draw Qi into his body. He looked like a "bloody immortal". Wang Goucheng originally wanted to hide away, but he couldn't bear the embarrassment of the other person's down-to-earth nature. Not only did he help find a doctor to treat the injury, he also placed him in the blacksmith shop and woodshed, and listened to him talk about the rare things on earth: there are no immortals, but there are "iron birds" that can fly in the sky, and "technology" that can talk thousands of miles away. After a few days of stable life, Lin Yu's cube suddenly jumped red and warned: [Low-level monsters are approaching, the danger level is low! Wang Goucheng panicked instantly - a while ago, the pigs from Butcher Zhang's house were taken away by the monster in the back mountain. He can only strike with a hammer, but can't even use a bow and arrow; Lin Yu has a broken leg and can't even stand firmly, and the two "fighting scum" are about to become monster snacks. On one side, he was suddenly thrown into the world of immortality, and on the other side, he was faced with an imminent survival situation. Wang Goucheng stared at the "unreliable" immortal next to him, and his mind was filled with questions: Is being associated with the word "immortal" in this life a matter of eight lifetimes of bad luck, or is he hiding some unexplained good fortune?
