"But now I need to get out of here before someone else shows up."
I was feeling quite confident after I had snuck inside and completed my objective. I then quickly but carefully snuck back from the way that I had come.
The guards were still there, but they were not very alert. Even if they knew that they were doing some important job, it was quite boring to guard something for the night especially when everyone is asleep.
However, I didn't want to make any mistakes and was more careful than before. I actually got scared when one of the guards yelled at the rat as I thought he had sensed me.
Whether it was the rat's fault or my own, I was extra careful when keeping my aura concealed. I quickly snuck out.
After that, I quickly went back to my room excited. I had managed to disarm those Mana explosives and the Dark Guild couldn't produce as much destruction as in the novel. I slept through that night with peace of mind.
