Western Fantasy the Sword of the Old Era

Although I, Meng Wu, am a civilian, I can challenge those who are stronger than me and those who have more rights than me for the sake of my family! What I conquered is not just the earth, but the wider galactic universe. PS: This book is a Western fantasy novel with Cthulhu elements added. I don't know if many people will read it on Feilu, but you can just read it if you like it. If the introduction is insufficient, please read the text. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
