Cain did not even realize what was happening and was unprepared, so Benjamin got a clean strike.
"You..."
At that moment, he lowered his head and looked down at the knife deeply embedded in his chest. The blade was now completely buried in his left chest, and Benjamin had even deliberately twisted the knife around to maximize the damage.
Suddenly, Cain’s expression changed. He looked at Benjamin with his eyes wide opened, his expression was a mixture of fear, shock, and doubt.
"W-why ..."
Benjamin looked very calm. Then, he suddenly pulled the knife out, threw it on the ground and replied casually, "Because you are not real."
Then, he looked at the wound in his chest. However, what he saw was surprising - the blood vessels around his wound looked as if they were sealed off, and not a single drop of blood was shed.
Cain was still in shock, but he suddenly calmed down.
"... You noticed?"
He asked slowly and cautiously.
