Zi Su and Brother Li choosing to collaborate with these Rainbow Flag players is understandable.
They were indeed running out of stamina.
Although on the surface, the two sides seemed evenly matched, Brother Li's group has never been able to seize the Level A Dealer position.
Therefore, there was already a significant cost difference in purchasing the Nine Dragon Elixir Pills.
Brother Li obviously couldn't get supplies from Instructor Ding. Though the price would be lower, it would increase the sales for everyone in Instructor Ding's sales chain, effectively giving up the competition for the Level A Dealer position permanently.
However, getting supplies from Natural True Man as a Level B Dealer was too costly, and he had to subsidize his subordinates, which was a significant expense.
Even if he could use other side businesses to lower expenses as much as possible, it was still difficult to sustain.
