"What's wrong?" Cecilia whispered but Sato didn't answer. Instead, he kept his eyes on the monster as if he has spotted something.
"When we start walking, don't make a sound. Move as gently as possible and try not to create any sounds from your footsteps. Stay close to the wall but don't lie on it. The shuffling sound between your clothes and the wall could possibly alert it." Sato spoke up after a while.
He didn't need to give Milo any instructions as the feline knew better. Apart from that, it was a master in tiptoeing and soundless steps so Sato was least worried about it. The problem was Cecilia. Being the daughter of a noble, it was understandable that she didn't know how to minimise the sound of her footsteps to become soundless, after all, her training would mostly focus on aristocratic behaviours as well as the knowledge of the kingdom's political situation and history.
AN :
[1] Qualitative changes occur at certain ranks. For example King rank. Logically (by the example used above), a level 14 King should be the same as a level 15 Special-Elite but the two can't be compared. A King would have a slight upper hand even if it were weaker in level.
Also, while it's said that the two comparisons in the marked paragraph are on par with each other, their attribute points distribution aren't necessarily the same but the total of points are.
