The exploration time agreed upon by the three guilds was 24 hours, enough for him to make a round of the entire secret realm.
During the search, Su Yu occasionally discovered some artificial traces remaining in certain canyons, such as collapsed buildings and stone pillars covered in vines, but the secret realm had been abandoned for an unknown number of millennia. These artificial traces had long decayed or been submerged by vegetation and were almost impossible to detect without a careful look.
Through these artificial traces, he speculated that there must have originally been zoning within the secret realm.
Flying south along the edge of the secret realm for over 5,000 kilometers, he saw a large lake covering hundreds of square kilometers. As he passed over it from high above, he saw a hundred-meter-long flood dragon swimming in the water, continuously devouring spots of blue light from the lake.
Azure Flood Dragon (Elite): Leader, Level 121, Aquatic Race, Flood Dragon.
