His hands were shaky at the prospect of cutting himself, but he didn't drop the sword. He stretched out his left hand and sliced through it with the sword.
The pain was instantenous and ravenous. It wanted to eat and become his whole existence.
There was something different about it compared to the normal pain in the game. It felt more like his arm was burning to ashes.
He could feel his arm still there despite being cut off. Only that something invisible was burning his invisible arm until he lost sensation of his arm completely.
He fell face first and allowed himself to cry. The pain was so great that he rolled around on the ground and cried for an unknown amount of time. The gods found it amusing. Many of them snickered and laughed.
He didn't stop crying until he stopped feeling his lost arm completely. The burning sensation had also stopped. When he came, he was already in his room back on earth. There was also a notification in front of him.
