Crossing the boundless ocean, Zhu Minglang stared at the sea's surface, knowing that if it weren't for Zhu Rongrong teaching him to use the fixed direction of the tidal surge for navigation, he would have long been lost in this sea with nary an island in sight.
Following the tide, he could at least discern a direction to move forward.
Under the blue sky and over the azure sea, Zhu Minglang had the Heavenly Slaughter Dragon come to a halt on the water's surface and then quietly felt the breeze blowing past.
If the initial direction hadn't been wrong, the wind direction would also be constant.
When the wind direction and the tidal surge just so happened to converge, that was the sea he was searching for.
Fortunately, as a Dragon Shepherd, his perception of nature was exceedingly keen. Otherwise, even with this knowledge, he would still be lost.
There was no sea fog, nor were there any storms, just an exceptional calm all around.
