With Qin Wushuang’s protection, Miao Zhongxia did not encounter any threats while he was getting his own jade plates. Soon, he found his seventh jade plate.
After they left this place, Qin Wushuang made a promise with Miao Zhongxia to spread the information about the ambush to everyone. When they met the other Stargaze disciples, they would warn them to prevent them from suffering a great loss.
Since Qin Wushuang had finished collecting the jade plates, he no longer had any burdens. Thus, he was much more efficient in spreading the information than Miao Zhongxia.
Especially at night time, they needed to stay alert if that person intended to harm them. As per the rules, whoever attacked their enemies would influence the overall grade of that country.
Thus, something like the sneak attack was not honorable behaviour and had rarely occurred during the preliminary round.
