The memories Jiang Li left with the White Marsh Emperor's Dynasty were painful to endure.
For the human cultivators, the White Marsh Emperor's Dynasty was an excellent battlefield, a whetstone. Anyone who was ambitious about their own battle strength wanted to experience life-and-death trials amongst the beasts, to achieve growth.
After all, beasts could reproduce more rapidly than humans and grow faster in the early stages, making them stronger than humans of the same level.
Jiang Li was an exceptional case. After reaching the Nascent Soul Stage, he felt that his cultivation was growing too rapidly, which was detrimental to his subsequent cultivation. To slow his progress, he visited the White Marsh Emperor's Dynasty.
At that time, the beasts were oblivious to the fact that Jiang Li would later become the Human Emperor. One after another, they tried to kill him with all their might.
