Albert left the seventh floor of the west wing in the demon king's castle and headed down, he could tell that for some reason his new master was mentally exhausted. Perhaps it was due to the circumstances that surrounded this castle and the fact that the red ogre settlement had accompanied him, or maybe he had expended a bit too much mana during the fight in the rocky plains.
Albert guess was that Lord Ty had most likely isolated himself for centuries and kept himself in a special state similar to sleep in other to recover from a certain injury. He wasn't completely sure about the details but it wasn't like it mattered to him anymore.
He had already used a demons pact when he offered his life to Lord Ty so he wouldn't betray him no matter who he was. Even without the pact he would still never betray him, after all, he was someone that had saved both his and Erin's lives. Going against him would do a lot more than dishonor his demon heritage.
