When Gu Hang placed several new "Black Boxes" in front of Wu Jiarong, her mouth opened wider than it ever had in her life.
Where on earth did these things come from?
Initially, she had suspected they were provided by the Gu Family, but then she realized even the Gu Family wasn't capable of this; later, she harbored the daring thought that perhaps Mr. Gu was the son of some great Sage from the Sect of Mechanics, but then again, any Sage would undoubtedly value the Black Boxes more than their own flesh and blood. Those who had mechanical parts replacing everything in their bodies except their brains, did they still possess familial affections? That was uncertain.
After that, Wu Jiarong couldn't think of any other reason.
