The so-called second priority selection right means that among all the dropped items, Dong Liu Cang Shui's side would choose one first, followed by Ye Rong's pick.
In other words, what he would get would be the second-best item dropped by the BOSS.
However, if there was only one item dropped, it naturally wouldn't be Ye Rong's turn.
The condition proposed by Dong Liu Cang Shui was that as long as Ye Rong participated in any entry-level task to help, he could choose one item with the second priority selection right. This reward was already quite generous, and even if he didn't consider the favor of saving face, he might agree to it.
A few players behind Dong Liu Cang Shui were obviously unhappy, but they held their tongues and didn't speak up, as they all thought that Ye Rong was given too great of an advantage.
