Wasteland Era: My Mobile Fortress Sells Everything

No one knows where this huge mobile fortress came from. They only know that it wanders in the wasteland all day long, never actively attacking, and no one can break it. The owner of the fortress is named Xiao Ye, and he sells everything: food, arms, medicine, pets, mutant serum, mutant beast cores, armored vehicles... He has his own set of rules: he accepts not only the currency of any faction, but also "valuable" things, such as your loyalty, the head of your enemy, or your frivolous promise. Some say he is the savior of the last days, while others say he is the devil who plays with people's hearts. However, as long as you have the money and the value... You can find this mobile fortress and trade it for anything you need. … "Beer, drinks, mineral water, peanuts, melon seeds and ham sausage! Iced cola, iced black tea, white wine, cigarettes and jasmine!" "Hey! That zombie biting my tire! You have been permanently blocked by me!"
