After transmigrating to an ancient dynasty, Su Wen used his knowledge and the System to rise through the ranks in just three years, becoming a second-rank official and entering the imperial court as its chief minister.
But his meteoric rise had drawn too many eyes. He decided to keep a low profile for now, making sure his brilliance did not completely outshine the other first-rank ministers. He would submit useful intelligence and inventions bit by bit.
One day, he found a pretty calico cat at the foot of the imperial city. It looked pitiful and adorable, and kindhearted Su Wen took it home, ready to become history's first cat slave.
But from then on, the inventions he gave the cat to play with would occasionally go missing, only to be cleverly discovered by someone and presented to the Empress.
His analysis of current events would also somehow find its way to Her Majesty's ears, covering everything from astronomy and geography to the most trivial matters.
At last, Su Wen figured it out. There had to be a mole in his household.
Just as he was about to put some effort into finding the mole, the Empress summoned him for a private talk. Looking at Su Wen, who had been alone with her for what must have been the umpteenth time, she smiled.
"Why so nervous? Don't you like petting My fur?"
"Want Me to meow for you, too?"
