In fact, it didn't mean that the old Taoist had opened up the Ren and du meridians after being possessed, and that his divine power had increased so much that he could kill anyone in his way. Cao Ding's upper body had indeed stimulated the old Taoist's potential, but in reality, no matter how much he stimulated it.., the old Taoist's potential could not be stimulated to a level beyond that of Bai Yingying and the Little Loli.
The reason why Cao Ding was able to kill two warriors consecutively like chopping melons and vegetables was because Cao Ding had killed them back then and suppressed them for 500 years. This was a fear that was imprinted in the depths of their souls.
In front of Cao Ding, these three fierce and murderous warriors could only be reduced to thin and weak quails.
This was similar to how Bai Yingying could be very cold when she was alone, but when she faced boss Zhou, whose bloodline suppressed her, she would immediately become "Sob sob sob".
