After Thousands of Iterations at the Beginning, Who Can Stop the 100-Meter Giant Sword?

[Black technology + evaluation + fantasy products + interstellar] Yu Fei, who just entered college, accidentally got an iterative system and needed to conduct an evaluation to collect popularity points. As a result, outrageous products appeared in front of the audience one after another. It can be used as a toy with a 100-meter giant sword. A shovel that can hollow out mountains. A projector that makes the sky change color. A small flashlight that can destroy stars. Each outrageous product made the audience say the special effects are so enjoyable! But when the live broadcast permission was turned on, the audience realized that they seemed to be the real thing! ! ! (The protagonist is not very smart, and his identity will be revealed after a few chapters, so be cautious if you don't like it!)
