Invincible in New Eridu Thanks to Ten Years of Solitary Bamboo

(One heroine: Yidhari + pure romance + some original plot) (The ten-year-old lone bamboo is just bait to attract readers. This is actually a completely serious story. I'm a shameless hack who put a dog's head on a sheep's body. Mad about it?) After twenty-five-year-old Ren Yunfei elbowed the concrete floor, he not only survived, but also unlocked a thunderous, pig-stuffing, universe-defying super System, along with an incredibly powerful thunderous divine weapon. With the weapon in hand, Ren Feiyun can kill anyone who stands in his way, be they gods or demons. No one can stop him! With one sword, he slays Bringer, and the entire Public Security Bureau becomes his harem. With one sword, he destroys Lorenz, and the entire Obol Squad becomes his harem. With one sword, he kills Sarah, and Yidhari becomes his harem. By the end, every evil villain is gone. Everyone has a bright future, and no one will ever get killed off again. How wonderful. (Most of this is made up.) With a protagonist this powerful, he must be working hard to get stronger, right? No, no, no. Your Uncle Ren Feiyun is a fellow fan of Yuma. About Ren Feiyun: Hoshimi Miyabi: “He actually took advantage of the fact that I can't fly to win. That's despicable.” Tsukishiro Yanagi: “I know it's not nice to say this about my own child, but A-Fei really is a little... strange? Maybe I haven't done my duty as an adoptive mother.” Vivian: “He actually stopped me from climbing the air conditioner. Unforgivable.”
