I Am a Test Engineer in Another World

Zhou Heng was a product manager in his previous life. Unexpectedly, after time travel, his first job would be to test flying swords for others. The last tester handyman hadn't found it yet, but the sword flew back on its own. The steward kicked him: Stop lying down, go up and fly around, the delivery is still waiting in the front yard. The problem is, this sword only knows where to go, not slow down, avoid people, or stop. In order not to become the next missing person, Zhou Heng could only save his life while writing down every accident. Why did the flying sword hit the wall? Whose responsibility is it if the magic weapon breaks? What did you change before the accident? While others were busy refining weapons, he first provided testing, records and after-sales services to the world of immortality. Later, when it was his turn to learn to make weapons by himself, he realized how annoying that saying back then was, "Just change it and it'll be fine."
