Chapitre 581: The Sword

Alex felt a wave of spiritual sense coming from the other side of the corridor that ended at the room with the door, which was the dead end.

'Dammit! How did I stop such little way?' he wondered. 'Is there a seal in this place that won't let me leave using my techniques?'

If that were to be the case, he needed to think of something quick. Concealing himself wasn't going to help him against the spiritual senses, so he needed to do something else. 

He sent out his own spiritual sense around him while thinking of what he could do. 

Just then, he realized that his spiritual sense wasn't working beyond the door behind him.

'I can hide there,' he thought. He needed to find a way to get inside. From what he remembered of seals from all of these memories, he needed some sort of key to open it.
