We Agreed to Become a Disciple of the Sword Sect, but Why Did We End up Refining the Flying Sword?

Travel through the world of strange things and visualize the gods and Buddhas. Yang Zheng, a young man from a humble background, was refined into a flying sword by a witch. Fortunately, he opened the panel and as long as he absorbed the blood and soul, he could infinitely improve the quality of the flying sword! If you want to practice swordsmanship, do it well. If you don't want to practice swordsmanship, then come in and practice swordsmanship for me. When he meets a sword master with a pure heart, Yang Zheng becomes a sword of justice, specializing in killing evil people and evil spirits. When encountering a bloody-minded sword master, Yang Zheng turned out to be a most evil sword, and he could kill all the gods and Buddhas with his sword. Time travels backwards, and the sea changes. Yang Zheng suddenly looked back, he was already invincible in the world!
