Gale was summoned into a mysterious world of magic and monsters for no particular reason. Thrown into squabbles of beings vastly higher than him, Gale strived to make a place for himself in the vain dream of immortality and a better world.

That was six years ago.

Beaten and battered from years of brutal war, Gale finally had enough and resolved to start over a new peaceful life in a totally unremarkable town with his trustworthy companion, Vale. Give up the weapon of slaughter and take up a hoe? That seemed like a fine deal to him.

Unfortunately, the valley wasn't as unremarkable as he thought it to be. Dictatorial governing bodies, suspicious practitioners, an exceedingly unwelcoming guest, and a secret that would change the entire world, all impeded his peaceful life. Gale will need all his mental stability to keep his temper in check, lest he brutalises his way out of trouble. Again.

Demon Emperor Meng Xianji: “Mockers, kill! Those who defy me, kill! Strong people, eat! Valuable treasures and materials, eat! Good equipment, steal!”

Wine God Xiao Sanshao: “Why must you be so brutal? If there’s something wrong, can we not just all sit down and have a nice chat? I’ll teach you how to taste wine, youngster!”

Medicine Immortal Tian Can: “You guys chat first. My condition today isn’t very good, so I’ll go rest first…. If you want to concoct some medicine, tell me after I wake up….”

Godly Craftsman Xi Hong: “Didn’t I just upgrade your equipment yesterday? What are you afraid of? Attack, youngster! Isn’t that right, Chen Nan?”

Formation Spirit Chen Nan: “En…. How about you go ask Mao Yue.”

Beast Emperor Mao Yue: “Today’s sunshine is too bright. I’m recalling that cat of mine who died because of menstrual pain….”

Hong Xiaobao: “Can you guys not be so misleading?”
