When Sato and Xin Feng came back to the dead campfire, they found everyone already asleep. The reason why they were all asleep, was because they were sure that everything would be fine with Xin Feng going together wih Sato Ato. Other than them being at ease because Xin Feng's decision to assist, they were tired too, and also hungry. Hence why, it was best for them to take a rest and consume less energy.
"Wow… Didn't any of you even think of preparing the utensils to cook?" When Xin Feng was close to everyone, he spoke out his remark.
Because Xin Feng spoke at a normal volume, only a few people woke up. Those people were Akira and Hiroto of course, since they were the most trained people out of the rest. One had to wake up in time to attend adventures, and the other had to wake up in time to attend the delivery of cargoes.
