Song Yun took 1.5 million out of the 2 million, giving about 15,000 to each of the elite members of the Shura Alliance who came to Guangzhou, and kept 500,000 for himself.
It's like the saying goes, make money together.
An organization is basically a conglomerate of interests. People gather together, and under your leadership, they make big profits. If you try to pocket all the money yourself, sooner or later, you'll be abandoned by this interest group.
This isn't just true for organizations; in fact, the entire establishment is just a coalition of interests. Not only now but even in ancient times, if the Emperor monopolized all the benefits and left the people in misery, someone would surely rise against you. But if you, as an Emperor, ensured everyone was well-fed and well-clothed, living comfortably and prosperously, then no one would oppose you. That's the principle of shared interests.
