People Are in Another World, Starting with the Source of Fire Cultivating Immortality?

Dear guest, welcome to my fairy weapon arsenal, where we will serve you wholeheartedly. What? A fairy puppet that can fight independently? It has the functions of killing enemies across levels and searching for invisible spiritual weapons? Oh! Your Immortal Weapon Master strongly recommends you to use this: Terminator Type I Immortal Puppet! This weapon not only has explosive combat power, but is also equipped with a laser gun, electromagnetic shield, and fairy infrared scanner. It can withstand a powerful blow from a foundation-building immortal cultivator, and it also has a stealth fairy search function. Let those criminals who want to get close to you have nowhere to hide. Immortal scientist? Oh, no, no, no, please call me the fairy arms dealer. Our service tenet is: to provide the sharpest spears for powerful immortal cultivators, and the strongest shield for weak immortal cultivators. Of course, if someone wants to cause trouble, this businessman will happen to punch him twice.
