Compared to Lu Hong, Augustus preferred not to kill if he could avoid it. The reason he killed Tie Shilan and Yu Lang was that they had participated in the ambush against him.
"What should we do with them?" Lu Hong pointed at the nearly two hundred strong from the Cold Extreme Divine Path and the Wanmu Divine Path.
"Just leave the Strength Divine Path, and I will let bygones be bygones," Augustus said. Before he was ambushed, he had defeated many heretics along the Strength Divine Path and allowed them to leave; however, no one heeded his advice, and they continued their wicked deeds once he was gone.
Once bitten, twice shy—Augustus certainly wouldn't allow them to return to the sixth trial.
"We are willing to leave the Strength Divine Path." With their boss dead, the morale of his underlings naturally dissipated. They were all Third Transition strong, and the journey of cultivation had not been easy. It was clearly not worth dying for nothing in such a place.
