Hello, I onced read this book based in modern day china, basically the Mc is smart and can build stuff, also his friend is a police woman, he has a sister in school he also decides to learn wing chin martial art. And lastly he helps someone create a hover board. Sorry for the horrible description, it has been a long time since I have read the novel thank you.
I only remember details. Searched x-ray first, then vision. Pretty sure the name was something like X-ray vision at first too. I pretty much read most novels, excluding ones marketed at a female audience.
