Having sent everyone away, Zhao Guang's house finally... didn't seem to quiet down.
With so many pigs oinking and squealing, it required closing doors and windows to find some peace from the noise.
Turning on the air conditioner, Zhao Guang began to research his next spell, the Simultaneous Writing Skill. Indeed, just like before, there were many aspects of its structure that could be improved.
Zhao Guang couldn't believe that other mages wouldn't improve it, but improving a trick had little benefit.
The most crucial point was, after improving it, the learning difficulty for most Mage Apprentices would increase significantly.
These tricks were merely to nurture apprentices, to cultivate their spell research abilities, and couldn't be made too complex. Lately, Zhao Guang had researched many mathematical models and a large volume about the essence of spells.
Although he hadn't brought about a radical change, he already had his own ideas on analyzing and improving these spells.
