Yang had already mastered using his powers to attack zombies by mastering control of his water power.
He had been using his water powers by rotating and condensing them thinly to act as blades.
The other people with superpowers were also the same.
Even though they were more aggressive than water and could deal a lot of damage to the zombies, the people with superpowers in the team were clearly stronger.
While they were on the road, the others kept on training their combat ability by fighting the zombies they had encountered.
They were also already familiar with the road, so it was easier for them to go back.
They continued following the road that they had used before, and they had only detoured when they were near the suburban area near the city area where they had encountered a level 3 zombie before.
