Over a minute had passed since Sato and Cecilia had started exchanging blows. Rather than calling it exchanging, it was more of Cecilia attacking with Sato running around the place as he tried to dodge. Cecilia didn't give him any breathing space to counter so Sato was always forced to be on his feet lest he gets injured. However, it wasn't like there were no gains in this for him.
Having survived for this long, Sato became confident in his suspicions. Cecilia couldn't use her full strength. Otherwise, he wouldn't have had any chance to react and would have been dead long ago.
AN :
[1] Let's suppose Maldora Canyon is divided into outer, mid, and inner parts with the Lorls river running through each part. Let’s also assume the shallow part of the river to be between the surface of the river till 15 metres deep.
In the outer region, the shallow part of the Lorls river doesn’t have many strong monsters with the average lvl around lvl 15 -20. in the Mid region, it would be lvl 21-40, though the stronger ones are harder to spot. But at the inner region, the shallow part of the Lorls river houses lvl 41 and above.
The current place the duo are in is the mid-region so the ‘shallow-dwellers’ here simply refers to the monsters that stay within the shallow part of the river. As they are closer to land, they are able to sense some of the events that occur at the river’s banks.
[2] Reference to the underworld. In summary, dying.
