The children who got their hands on firearms, after having a full meal and especially tasting the flavor of a small glass of red wine, were entirely committed to sacrificing their lives for Tang Zheng. They always wanted to do this, but no one needed them before. Now that they have finally found an opportunity, they naturally wouldn't give up.
In the Wasteland World, people die every day. The children had already grown indifferent to the concept of death, it wasn't a fear anymore, but a symbol.
Tang Zheng thought that when he ordered them to attack the Duangang Mercenary Corps, the children would at least exclaim in surprise. However, they were actually expressionless, each of them hanging their heads low, learning how to use firearms with all their might. They refused to use live ammunition for practice and adopted postures for aim practice instead.
