It's like some kind of geographical boundary line.
Since Xia Nan left Sheep Horn Town, he truly delved into Su Bin Province at the southernmost tip of the continent.
The surrounding environment began to change rapidly in a way that differences could be clearly perceived.
The terrain, originally a mix of hills and basins, gradually transitioned to open plains where the horizon was visible at a glance; large forests and fertile farming areas gradually disappeared, replaced by ponds, swamps, and wetlands that could be seen everywhere.
The air was filled with moisture, and the sky was frequented by water birds like herons and storks, while all kinds of insects became more prevalent.
Walking in the wilderness, Xia Nan always felt as if a layer of moisture was clinging to his skin, damp and sticky.
Luckily, he was in strong physical condition and had a good ability to adapt to changing environments, showing no signs of acclimatization problems.
