Although the Soul-chasing Bow was unreasonably strong, Chu Xuan was not able to use it to its full potential at the moment. He could not lock onto and kill a person with just a thought.
No matter how powerful a weapon was, it still needed to be wielded by someone with sufficient strength.
At the current stage, Chu Xuan could either lock onto the enemy with the soul-chasing seal, capture a trace of the enemy's aura, or use other methods to locate the enemy.
Only by doing so would he be able to ignore distance and space and shoot them to death.
Moreover, if the person he had locked onto was too strong, the person could also withstand his attacks.
After all, the power of the arrows was also related to his own cultivation.
Given Chu Xuan's current first-level Supreme realm cultivation, it was definitely impossible for him to kill a Heaven realm expert.
