Wang Yi was reborn in a parallel world. Just when he was gearing up for eighteen years to flex his muscles, the belated Golden Finger came online and threw him into a low-magic world for three full years. After learning a lot of magic knowledge in three years, Wang Yi was kicked back to modern times…

What is the combination of magic and technology? Magic technology? Black technology?

The troublesome material science problem was solved, and many mysteries became reasonable after the addition of magic.

However, when Wang Yi just came back, he still decided to use a captured Wraith to knock out an artificial intelligence to be his housekeeper…

Also known as “My Skull Can Turn Screws”, “This is not magic, it’s black technology”, “There is no magic in this world, everyone should believe in science”, “There are no ghosts in the mobile phones I sell”
