The journey back to base was not without difficulty. They encountered a few more waves of wild creatures, and suffered more casualties. Ye Chong did not interfere too much, as he decided to let the students do most of the fighting. His objective was to train the students. Being overprotective would not serve this purpose. As long there were no mass casualties, he would refrain from interfering.
This process of elimination was cruel, but necessary.
Once they were back to base, everyone felt relieved. In the next few days, Ye Chong did not bring them out for more battles. Instead, he ordered them to analyze their fights. The analysis process would help new soldiers mature faster, and help them understand more about teamwork.
The students had now experienced the cruelty of battles first hand. No one slacked in their roles. That would be like giving up one's life. When battling in groups, survival relied on more than just on individual strength, but also teamwork.
