Infinite Weapon Evolution

When he woke up, he found himself in a wild world. Surrounded by ferocious beasts, he may receive a box lunch at any time. No matter how you look at it, he is just a bit player. Like all time-travelers, he also has a system. However, this system seems weak at first glance. He has to rely on his punches and kicks to defeat it. There are no shortcuts and no cheating. Facing a tall ape, he decisively threw a stone—— "Poof" - steady! Allow! Ruthless! For the first time, fear filled the male monkey's eyes. Then he peed, marked his territory, and began his wild rise. This is a story from the wilderness to another world and then to the sea of ​​stars. This novel and its characters are purely fictitious.
