Choi Han quietly mumbled as the Dark Elf continued his report.

�The knights look like they have some type of signal flare.�

They would probably use the flares to inform the palace that enemies were trying to infiltrate the underground waterways.
Everybody looked toward Cale who then started to speak.

�We will take the knights down and go in through there.�

At the river flowing southeast starting from the northern part of Renche�
There was water flowing out of the waterway located at the end of that river.

�Haaaaa. The smell is terrible even when it�s cold.�

One of the four knights guarding the waterway pinched his nose and shook his head.

�At least shit doesn�t flow out of here.�
�That is true.�

There were three waterways that started from the palace and ended at the river, with the water flowing out of this waterway coming from the kitchen, palace garden, or the knights training ground.

�What nonsense. What kind of knight has to stand guard at a place like this? Don�t you agree-, huh?�

One of the other knights who was also pinching his nose and grumbling opened his eyes wide after suddenly seeing something black appear.
In that short moment�

�Ugh!�

He gasped after feeling something hit the back of his neck and plopped down on the ground.

Plop. Plop.

All four knights quickly fainted.

�Amazing.�

Tap.

Cale then landed where they had been standing. The Dark Elves smiled as if they were embarrassed by what Cale had said.

�We are known for being quick.�

The Dark Elves who were embarrassed but still confidently showed off about their abilities took out three flares from one of the knights� pockets.
It looked like a magic device that worked similar to a firework and looked quite strong. JrNovels.com
