This move might not be entirely honorable, but only Li Yifei knows that achieving this was already difficult enough for him. They have been fighting for so long, and though it may sound easy, Li Yifei was very careful and focused with each move. He and Xu Shanshan had been trapped in that temple for over ten days, replenishing their physical energy after coming out, but their stamina hadn't really been restored.
Simply put, Li Yifei was tired. He worried that if things dragged on, he would deplete his stamina too much, and a momentary lapse could let the opponent take him down easily. At that point, Xu Shanshan would certainly lose to the opponent.
That's why he twice signaled Xu Shanshan to prepare to make a move, using this somewhat dishonorable tactic.
Yet, from another angle, it was only fair that Ruan Xiaotian was unlucky. He was still too arrogant, neglecting the presence of another Innate Expert after gaining the advantage.
