The student who was carried out was not properly equipped with their breathing mask. During the rescue process, they carried the mannequin on a stretcher and accidentally bumped their breathing mask on the fake head of the mannequin. Just like that, they breathed in the CN tear gas and choked. They covered their throat with their hands and coughed loudly as they cried crazily.
Because of this sudden accident, the students from the country couldn't care less about the mannequins. Naturally, they focused on the student from their country.
The radio station received their cry for help. The fully equipped rescuers immediately rushed into the poisoned zone and quickly brought out the student who had inhaled the CN tear gas.
Fortunately, another student from that country reacted quickly. He helped the student up and rushed out. He didn't even waste a second. He immediately headed to the entrance, which led to a faster rescue.
