Originally just a mercenary, training others was something Gao Yang could manage albeit with difficulty, but command, especially command over a group that numbered in the thousands and could barely be considered an army, as well as manage their food, drink, and daily necessities along with their families, was asking too much.
These people, including Gao Yang, were adept at fighting small-scale skirmishes, and commanding dozens or a few hundred soldiers in battle was still within their scope of expertise. However, temporarily taking charge of the whole Skull Gang exceeded their capabilities. Nevertheless, since there was no one else available for the task, Gao Yang felt no psychological pressure. Even if he did poorly, he certainly couldn't do worse than the current situation.
