My Mom's Rant: The Things I Invented Are Really Useless?!

As the Dragon Kingdom grows ever stronger, the United States imposes a technological blockade.

At the same time, the United States scores major breakthroughs in various fields of technology.

"Room-temperature, ultra-high-pressure superconductivity," "GPT artificial intelligence"...

Su Chen, a third-year vocational college student, is obsessed with inventing things, but people call him a "useless inventor."

His mother even brings in a TV crew to complain:

It's not that I'm saying his inventions are useless. They really are useless!

Su Chen awakens the [Practical Handicraft System].

And so, while Su Chen's inventions look useless on the surface, they actually contain some of the world's most advanced technologies!

[Hovering Kettle]: It can float, but it can't heat water. It helps the Dragon Kingdom achieve a breakthrough in "room-temperature, normal-pressure superconductivity."

[Lying Lie Detector]: It can lie, but it can't detect lies. It helps the Dragon Kingdom usher in the "era of artificial intelligence."

Household air conditioners powered by controllable nuclear fusion, learning tablets using quantum computing...

With Su Chen's help, the Dragon Kingdom completely crushes the United States, making civilizations across the universe tremble!
