Returning to the abandoned ancient city once again, Rod felt quite emotional.
In less than two weeks, the traces of their battles here were almost invisible.
The black fog had swallowed everything, making it look as if no one had ever been here.
New monsters had been born in the areas that were once cleared, and in such a short time, their strength had reached the Strong Level.
Even though under Rod's command they were just a matter of a punch or a sword and posed little threat, the very fact was chilling.
Anna felt the terror and cold deeply, her enormous horse body instinctively moved closer to Rod, and she asked in a low voice, "Why do these monsters grow so quickly? You clearly killed them just recently."
Rod replied in a deep voice, "The concentration of black fog here is very high, so the monsters born are naturally very strong. Look."
He pointed casually, and on the shattered ground, a thick black liquid was flowing.
"Black water!"
Anna was startled.
