Zeng Han reacted quickly. The moment he sensed something was wrong, he immediately flew off, escaping without a care for the lives of his fellow disciples.
In his mind, only by preserving his own life could he even consider anything else.
The path of cultivation is one where it's either you die or I survive.
Zhang Yan's sword escape moved as fast as lightning. If he were even slightly slower, he'd perish under the sword. Those fellow disciples left behind might even buy him a moment of delay.
Once he returned to the sea boat, protected by the prohibition arrays, he naturally wouldn't need to worry about Zhang Yan causing him trouble anymore.
Since he had acted so decisively, by the time Zhang Yan had killed Shen Minggu and circled back to seek him out, Zeng Han was already less than a hundred zhang away from the Mysterious Snake Nine-orifice Sea Boat.
Seeing he would reach the sea boat in just a few moments, Zeng Han couldn't help but reveal a look of delight.
