The sneak attack by the team from the north wing had backfired. After losing one of their members for no apparent reason, the morale of the north wing team had visibly lowered. After all, it wasn't that easy to kill a posthuman with additional lives. Nobody knew how powerful that attack was since it managed to, in a single instance, use up all the lives that the victim had accumulated.
When they continued fighting with Lin Sanjiu and her team, they started losing focus and accuracy. Even though Reno risked getting slashed by one of their enemies from the back, he created an opportunity for his sister to gain more lives. Finally, the number on Rena's back rose to 4. With that, Top Hat's team had already lost one member and two lives.
