If the Black River Heavenly Monarch is willing to give him some face, then perhaps he could swallow his pride to plead for Jing Yan. The problem is, it's unlikely the Black River Heavenly Monarch would grant face to Yuantong Immortal Venerable. In such a situation, sending a message to intercede would only embarrass oneself without saving Jing Yan's life.
"Clan Chief Xin Si, I too wish to protect Jing Yan, but he is within the Yellow Spring Cave, and my reach does not extend there!" Yuantong Immortal Venerable shook his head helplessly.
If it were outside the Yellow Spring Cave, Yuantong Immortal Venerable wouldn't hesitate to fight the Black River Heavenly Monarch. However, for matters happening within the Yellow Spring Cave, Yuantong Immortal Venerable cannot enter to seek the Black River Heavenly Monarch.
