One of the black men came up and tried to mediate, "Zhang Liu Yi, that’s not what Yue Zhong meant."
Yue Zhong retorted coldly, "No! That was exactly what I meant, if I were to be the leader, and send you to your deaths, you will have to obey! Only when orders are followed to that standard, that it will be possible for me to join you guys, be your leader, and give you a chance at survival."
Being the leader of this group of people, Yue Zhong had to share his precious water and food. He would have to divert attention to care for their safety and wellbeing, it was natural he wanted the authority over them. Otherwise, it was not possible for him to help them.
The main thing was that this world was so much harsher than Earth, there was no clean water or food, no matter how strong Yue Zhong was, he could not sustain all of them.
