Source of the Killing Intent

"Let's get into that building. I don't know what is going on with those three, but we have to be careful. I don't have a good feeling about that building." Henry stated to the two, before he took a step forward and began heading towards the building where Olivia and the rest of the group had entered.

As they approached the building, Henry could feel just what Olivia and the rest of the group felt. As he approached the building, the killing intent intensified.

But as soon as he passed through the barrier that was present around the building, the killing intent suddenly disappeared. This was something that Henry did not understand.

But nevertheless, he understood one thing, that was the fact that inside this building, there had to be someone that was controlling the killing intent.
