Chapter 406 - Barren land
'It will be very difficult to kill those when they will activate their iron skin. I need to kill them before they activate that technique. But still it will be difficult to kill all these ten monsters at the same time.'
Sam thought that but at this time he was already prepared to shoot those Monsters. Right now he was mostly combining some of his skills to attack those monsters so that he could kill those 10 monsters at the same time.
Before anything he quickly came toward those Monsters. You can say that he already came in front of those Monsters and instantly uses his confused ray toward those Monsters.
This will make those monsters confused for 1 minute and this will be enough time for him to kill them. He just hoped that in this confused state those Monsters did not use their iron skin technique.
