Chapter 299: Chapter 164: Scientific Genius_3

Yan Fei's confidence in accepting the challenge from the Taekwondo master stemmed from his realization of his own strength's position after the battle with the bearded Al-Assassin. Although he was no match for Huo Shan and Duan Hongye, outside of those God-level experts, he was nearly invincible within the innate realm. Moreover, he had one ultimate trump card, which was the black sphere.

In the end, he could grind the opponent to death solely through attrition.
