Only after Huinan Si narrowly defeated An Dongxu did Zhang Xiaohua gain a further understanding of the martial arts of the Grass Division.
Huinan Si is the fourth Arhat in the Grass Division ranking, and is slightly stronger than An Dongxu, the ninth Vajra of the Pill Division. This means that any of the top five of the Ten Great Vajras could easily match or defeat an opponent from the Grass Division, showing how weak the Grass Division is in Tianmu Peak. It also explains Chen Fengxiao's surprise and delight at Zhang Xiaohua's skill last night, as well as his determination to protect him in the dining hall, even if it meant offending Wu Dalang of the Pill Division.
Soon, the third gambling duel was announced by Lei Gongfeng's loud voice. This duel left everyone shocked. The Pill Division sent out their Great Vajra, Zou Shuming, and instead of Zhang Xiaohua going up for the Grass Division, it was shockingly Chen Fengxiao, the leader of the division, who was their surprise pick!
