Only Yao Honglei herself was at the Nascent Soul Realm, with the support of the Blood Poppy Skill, so hardly anyone could get behind her or close enough to her. Therefore, unless the opponent launched a surprise attack, or had far superior strength with a strange and swift movement technique, it was difficult to exploit this flaw against her.
However, this bunch from Luofu Mountain clearly came prepared, specifically designing a strategy. They first used Immortal Palace cannon fodder to lure her, wearing her down in one wave, and then employed a targeted tactic, always having three people besiege her from the front, and one person launching sneak attacks from behind. This kept Yao Honglei constantly preoccupied with the threat from behind, preventing her from exerting her full strength and unable to achieve a quick victory, forcing her to eventually retreat.
