After swimming more than two hundred nautical miles in one breath, Zhao Sheng felt the crisis in his heart diminish slightly.
However, as soon as he stopped and time passed, that nameless sense of crisis in his heart quickly intensified.
Zhao Sheng had no choice but to leave again and continue his underwater escape.
In this way, the chase endured for three whole days.
During these three days, Zhao Sheng searched inside and out of his body and finally discovered a Divine Soul Mark on his twelfth vertebra.
Having been a Foundation Establishment Cultivator in his past life, Zhao Sheng was very familiar with Divine Soul Marks and knew they were extremely hidden and difficult to remove.
For other Qi Refining Realm cultivators, not to mention not being able to find it, even if they did find it, they would be helpless against it.
But for Zhao Sheng, the Divine Soul Mark was not unsolvable; it only required a lot of time to erode it.
