You should know that the reform process always starts easy and gets more difficult later. It eventually touches the deeper areas, and without someone formidable like a dragon, it's absolutely impossible to continue reforming and thus save the day.
In Cheng Guang's view, even if the Grand Secretary successfully implements reforms, it's merely papering over cracks, allowing the Great Yu Dynasty to appear glorious. It cannot eliminate the deeply rooted maladies that beset the dying stages of any dynasty.
As for how to go about it?
Cheng Guang himself doesn't know.
But he is aware that only those with exceptional innate talent might have a slim chance of succeeding.
He has read Xu Qing's examination papers from the county exam; they were upright and bold, brimming with the spirit of ancient sages. Moreover, the man has not yet turned sixteen. Such a person, presumably born with innate knowledge, could hardly be cultivated solely through secret inheritance to this air and manner.
