Wang Zhan was also quite shocked by Lv Zhenglong's words.
Before this operation, the education he had received always stressed that humans should not kill each other and that beasts were the greatest enemy!
It was only after he had been involved in a few incidents related to the Original Organization that he finally learned the truth earlier than most.
Because of this, Wang Zhan could better understand that some things were not appropriate to tell them, as they were still students.
Imagine if, one day, someone told you that the ideology you've accepted for over a decade was wrong, and that you couldn't blindly entrust your back to other humans but must carefully discern who to trust. This concern alone would significantly weaken the power of the Coordinated Strike Method practiced by most students in the Academy.
