Once he traveled through the world of Yi Nian, Wu Fan did not wait for the cold master or the peerless skills, but was bound to a system that called himself "Dora B Dream". This golden finger in the shape of a blue fat man opened its mouth and said "ding", and what it threw out was not a flying sword magic weapon, but a bamboo dragonfly, a lightning rod... And even an "air cannon" that was unheard of in the world of immortality! In a world where Yuanying is everywhere and golden elixirs are inferior to dogs, Wu Fan looks at the "black technology" props piled in the storage bag and the garbled codes that pop up intermittently on the system screen. Wu Fan can't laugh or cry: "Okay, we don't have enough magic weapons, let's use our imagination! What about flying with a sword? I'll fly on the bamboo dragonfly! Thunder disaster? I'll insert a lightning rod! Look how I can use this weird plug-in to rub the faces of various immortals against the alchemy furnace talisman!
