You have to speak softly when you speak ill of the instructor

Barton and Berg didn't believe that they couldn't beat an 18-year-old boy in a two-on-one fight. Barton, in particular, was trying his best to win. He had once defeated a fighting expert and became famous. He was very satisfied with his skills. He and Burke had been in a small group for a while, and they had coordinated their tactics during their training. However, the two of them couldn't beat an 18-year-old Jack.

Other than a few bruises, Jack didn't seem to have any injuries, so he didn't seem to be in a bad state. Barton and Berg were almost unable to get up, and the new students who were watching looked at each other in dismay.
