[Alternate World] Weapon Maker

Traveling through time is not scary, what is scary is traveling into a wild world... Traveling to a wild world is not scary. What is scary is that the wild world is full of brutal beasts and mutated plants... It's not scary that there are brutal beasts and mutated plants everywhere. What's scary is that the simple weapons of the Stone Age can't provide guarantee for one's survival at all… Holy shit! This other world is so dangerous, I really want to return to Earth as soon as possible! Grenades, mortars, assault rifles... Just think about it, just be realistic and start changing with cold weapons... ～﹡～﹡～﹡～﹡～﹡～﹡～﹡～～﹡～﹡～﹡～﹡～﹡～ Please give me your support for the new article from the author.
