I'm Playing Military Industry with My Sword

Sunuo didn't expect that he would be so unlucky. He went home to play in the back mountains and stepped into a hole in the ground. When he woke up, Sunuo looked at this era of raging wars and felt like crying. He looked at others who had to carry the system with them when traveling across the country, and then looked at what they wanted and what they couldn't do. Fortunately, I am familiar with this era, so I can only hug my thighs and hide behind to play with skills. This novel and its characters are purely fictitious.
