Jack sparred with the two ladies for half an hour before he forced them to quit by throwing both of them to the ground. He then ran into the tent while claiming that he was tired and wanted to sleep. Jeanny and the others were speechless by his rather unconventional method of ending the spar.
Everyone went to rest after that. They were woken up a few hours later by loud gongs accompanied by John's voice powered by mana manipulation. John knew everyone ignored his warning last night. He didn't care. They had to resume their journey at the appointed time. There was no exception, no matter how tired they still were.
Most of these people ended up feeling miserable through the entire journey of the second day because they were sleepy. On the second night, most of them went directly to sleep once they stopped moving.
John made sure everyone was aware that they were not on a picnic. They were on a quest with the world's fate at stake.
