Tripiṭaka was confident in his own strength, and even if the Destroyer had someone to back him up, he would not be afraid. He continued to run, without slowing down his pace for even a moment. As a God-Level Expert, one of the strongest people in this world, even those so-called super experts who stood at the human summit would only have one choice upon meeting him: to run. Tripiṭaka's opponents were only other God-Level Experts, which is why he was brimming with confidence facing Yan Fei, a Super Expert at the Innate Realm Peak.
This abandoned underground tunnel was actually excavated by miners over a hundred years ago, meandering endlessly without a known destination. Yan Fei now had no other path but this one, only by taking advantage of the winding roads here could he shake off the pursuit of that God-Level Expert behind him. If it had been on flat ground, he would have been caught by Tripiṭaka long ago.
