Interpreting ancient texts was an exceedingly mentally exhaustive task.
Just as Master Qianye had said.
Seeing the "ancient texts" was only the first step.
To deconstruct the array patterns, calculate, and reassemble them required a vast amount of computing power. In this regard, Gu Shen wasn't Chu Ling. His computing power was already strong among his peers, but after all, he was "human."
After dissecting a drawing, he distinctly felt fatigued.
"If... fully interpreting and deconstructing an array pattern takes four hours, on a day when I do nothing else... I could probably interpret five array patterns."
Qingzhong didn't require every single array pattern to be repaired.
By that calculation, the repair work indeed only needed a year to complete, but wanting to learn all the "ancient texts" on the diagrams would take over five hundred days, even if he invested twenty hours each day.
"Everything is difficult at the beginning."
