Unlike outside, there were no guards inside the mansion. Perhaps because the sound of the guards' movements would wake others up, thus, this noble ordered them to stand guard outside.
Although there was no one inside the mansion, that did not mean that thieves could sneak in easily because the thieves would have to face dozens of guards outside with fully prepared armors and weapons.
But of course, that did not work for Lucifer because he could use Shadow Movement to get into the mansion easily.
Since there was no one inside, Lucifer did not need to use Shadow Movement to move anymore. He could return to normal and move normally inside this massive mansion.
But there was one thing that made Lucifer wonder: he had checked many rooms but could not find any room containing money.
He had checked all the rooms on the first floor and had now checked half of the rooms on the second floor but still couldn't find the money room.
