The entrance exam for the freshmen of Dragon City University's Martial Arts Department usually did not forbid the spectators from cheering, clapping, taking photos, or even booing. There would be all kinds of sound, light, and electric interference.
After all, if they could not even withstand such a small interference, they would be treated as fodder even if they ran up to a monster. It would be better to get out of there as soon as possible so that they did not embarrass Dragon City University's Martial Arts Department.
On the other hand, most of the freshmen and their parents were professionals in the industry. They knew the rules. Even if they could not hold back on their reactions, they would not go too far. It was fine if they shouted a few times, but it was also rare for them to be noisy from the beginning to the end.
