My Flying Sword Has a Billion Handles

Chen Yu traveled to a supernatural world and found that the training system here was somewhat similar to the meat pigeon game. After upgrading, you can choose one of three enhancements, and collect relics to obtain powerful bonuses... The combination of various enhancements and various relics can have the effect of stepping on the left foot and reaching the sky with the right foot. But luck is not something everyone has. Chen Yu knew that he was not a child of luck, but he could replace his enhancements and relics. [You get Engraving·Copy, copy your spirit weapon, and inherit all basic attributes. Sold other enhancements and replaced them all with engraving and copying, so Chen Yu owned many flying swords. [You have obtained the relic·Flying Sword. See Flying Sword again. When you launch a flying sword, there is a chance to launch another flying sword. Sold other relics and replaced them all with flying swords. Seeing flying swords again, Chen Yu owned more flying swords... Until there were one billion flying swords. What about the Lord of Gray Fog, what about the Scarlet Eye, what about the Corrupted Serpent... Whatever you want, tell me about my billion flying sword.
