Klaus looked at Grey in shock, "You're planning to kill us, aren't you?"
"There was a little error, I'll sort it out. If you know you can't wait, you can enter and be like those guys." Grey retorted.
Klaus looked at the group of seven and the other few people in the array that were moving cautiously. Explosions rang out occasionally, followed by screams of pain. It was clear that getting through the array wasn't easy by any means.
"I'll just wait, it's not like I'm in a hurry anyway." Klaus cowered away.
"Coward." Grey spat on the ground.
Klaus pretended as if he didn't hear anything Grey said. There was no way he was going to stress himself when Grey could easily make them walk through the array without facing any challenges.
They all knew Grey's capabilities as an array genius and knew that as long as he was focused, he would surely be able to tweak this array, no matter how old it was.
