So now there were only two ways. One was to find a son-in-law, have a grandson, and then worship Gu Shanhai as a master.
The other was to do it himself, but no matter which method, the difficulty was extremely great.
The class system of scholars, farmers, artisans, and merchants had always been there. Even if he had become the wealthiest man, his social status was not high, and it was unlikely that the other party would think highly of him.
Therefore, at the table, Li Yu was constantly probing Gu Shanhai's attitude.
At the very least, he needed to know whether the other party harbored goodwill toward him.
This was the only place where he could obtain the inheritance of military tactics.
Gu Shanhai understood Li Yu's thoughts too; the man indeed had it tough, but he himself didn't even have military tactics at hand, so where could he get them for you?
