For the Qinghe Fund, the most suitable income model is the kind that brings sustained benefits.
The lifespan of a human is very short in the grand scheme of the world. How long can Ren He himself live? He wasn't sure either; being long-lived now seems more like a beautiful blessing than an assurance.
If it were about donating money, the Qinghe Fund would have no problem while Ren He was around. But what if he, too, disappeared from this world someday?
What would become of the Qinghe Fund?
Therefore, the best approach was to leave behind some eternal classics. He wasn't afraid of others questioning why he could write these things; why should he feel guilty for things earned through his own abilities?
The most important reason for leaving behind classic works was that, if Ren He one day left this world, the Qinghe Fund's income would never cease.
So the current model was what satisfied Ren He the most.
