Assuming the role of a Cloud River Realm cultivator and arriving at the Spirit Stream battlefield to deploy such overwhelming force was indeed unseemly.
If Tan Sheng had truly outsmarted Lu Ye on his own and caused him such a great loss, he wouldn't have acted this way. Being inferior in skill meant there was nothing to complain about; he could only strive to enhance his cultivation, improve his strength, and then seek ways to seek revenge.
But Tan Sheng had used the second ability of the tracking disc, leaving him nowhere to hide within the hunting ground, ultimately leading to his encirclement by many powerful beings from Ten Thousand Demons Ridge. He couldn't escape, and had to use the extremely precious Golden Body Token. The cost had been a hundred thousand merits, a heavy loss indeed.
The origin of the incident in the hunting ground lay with Tan Sheng, so naturally, the losses had to be recouped from the New Moon Sect.
