You're Testing a Kitchen Knife, But Why Are You Using it to Strike a Military Shovel?

Zhao Feng transmigrated into a parallel world and became a product livestreamer. For a whole week, he promoted kitchen knives, but for six days, no one showed any interest. Not only that, the viewers in his livestream room mocked him, claiming that everything he sold was garbage.
Unable to tolerate this, Zhao Feng couldn't hold back his anger anymore. In front of hundreds of viewers in the livestream room, he pulled out a military shovel and said, "You all said my stuff is garbage, right? Well, now I'm going to show you whether it's garbage or not."
"Clang! Clang! Clang..."
The kitchen knife struck against the military shovel and created countless sparks, silencing the whole livestream room. After a while, the screen was bombarded with numerous bullet comments.
"What the hell? Who taught you to test a kitchen knife like that?"
"This is insane! Such a good kitchen knife might end up ruined!"
"They asked you to test the kitchen knife, and you used it to strike a military shovel? That's just crazy!"
Gradually, news of Zhao Feng's eccentric testing method spread online, causing a huge sensation. Suddenly, he went viral and became incredibly popular. Not only that, but people also discovered that this livestreamer not only had a ruthless way of testing products but also exposed the behind-the-scenes secrets of the entire product-livestreaming industry.
