Lin Fan didn't notice this as he had been staring at the mark on the blade the entire time.
This was a mark that was like a lotus that was imprinted on the guard of the blade.
As he stared at this mark, even though there was no residual life energy in it, he could feel a unique sensation coming from it. This should have been the imprint of the Realm that Momonga had mentioned before.
As he felt this sensation, there was a strong yearning for power that filled him. He wanted to reach the realm that this mark was in, he wanted that power to make all that he wanted his.
This impulse became stronger as a look of greed filled Lin Fan's face.
Momonga knitted his brows when he saw this.
He had said all this because he wanted to test Lin Fan. He could still see that there was some kind of split in Lin Fan and he wanted to see just how bad the split was.
