Increasing Strength!
Ace was calmly sitting cross-legged and mulling over the new chain mission, which seemed like a disaster.
Even though he had managed to theft a duke-level tribe and a demon duke; this new mission was on a whole new level.
Because firstly, he had Noa's intellect to help him exceedingly in the last thievery, while this time he had to rely on himself.
Secondly, he managed to easily fool Livy and got his storage ring to help him with the last thievery, but this time he literally didn't know who might hold those keys.
Most importantly, this was the Life Demon Association which had almost the same status as the royal council and this was the organization had multiple high-grade rune crafters which simply mean their security measures might be even more solid than the royal council and Ace simply didn't have skills to see through or bypass their security.
