To the Merak Saint Son, a force like the Cyan Yuan Sect was far too weak.
The entire Sect had only one master at the Inner Refining of the Five Viscera Level. The others were just at the Inner Refining Six Viscera Level, and the rest had even weaker Cultivation.
These people were naturally not worth him targeting.
As the Merak Saint Son, targeting the Affiliated Forces of his own Merak Sacred Land while on a mission to deal with the Alien Race would not reflect well on him.
This mission was also a test for him from the Saint Master and the others, one that would affect his future chances of becoming the new Saint Master. For that reason, the Merak Saint Son played it safe. Otherwise, he would have arranged for someone to target the Cyan Yuan Sect long ago.
Chiyu Peak had been a prior example of this. It had suffered a great loss, and its already unstable foundation was severely damaged. Its Primordial Qi had been wounded again, and it still hadn't recovered to this day!
