Because in the Jiushan Realm, having no background, his life was also rather average.
Yet this person had an extraordinary talent in mathematics. After attending school for half a year, he stood out, and later successfully entered the Jiushan Sect, which could be said to have changed his fate.
In Zheng Fa's view, this person was somewhat like a combination of himself and Senior Sister Zhang, and thus he remembered him well.
Later, Gu Chang also displayed an uncommon but surprising talent to Zheng Fa—a talent in topology.
Although Senior Sister Zhang was not bad at topology, her main talent possibly lay in calculus or algebra.
She often found this abstract thing of topology rather headache-inducing.
Zheng Fa could totally understand!
But Gu Chang's performance in topology was so exceptional that even Senior Sister Zhang felt inferior, always topping the topology exams.
Gu Chang's mathematical talent, shouldn't Master Pang have taken him out?
