Exposed by Qing Yu's revelation of his identity, Master Kong Hai's eyes flashed fiercely but he did not panic too much.
The scene had actually been a melee involving four fighters, with Master Kong Hai and Shi Yi teaming up against Yuan Jianyi and Demon Young Master. However, because Shi Yi was slightly weaker and was not sufficiently on guard against Master Kong Hai, a fellow monk, he was killed outright by two aggressive moves from Master Kong Hai.
The spectators, being too weak, did not clearly see Master Kong Hai's surreptitious strike, but Yuan Jianyi and Demon Young Master, who were right nearby, observed everything in great detail.
Thus, although the exposure of his identity as a member of the Esoteric Sect caught Master Kong Hai somewhat off guard, he had mentally prepared himself before striking at Shi Yi. After all, killing a member of the Great Zen Temple would have had dire consequences whether he was identified as part of the Esoteric Sect or not.
