Precious Herb Garden

The lady in the veil Chyou seem to possess the ability to see through the formations which in this case was a very helpful ability.

With that ability, they could easily see through the weak points of the invincible barrier and weaken it with their attacks until it breaks. Otherwise, they might as well be here all day just attacking aimlessly and the wall wouldn't even show signs of weakening.

"There." Chyou whose eyes was closed suddenly opened up as she pointed towards a particular direction.

The four people immediately started to attack that specific point with their blades, repeatedly. Since David had been seen as a weakling and had been underestimated by the five of them, David decided to keep it that way so they wouldn't see him coming at all by the time he decided to attack.
