Lu Yuanshan had already visited the Qingli Sea three times, gaining a preliminary understanding of its power layout, customs, and civilization, and was no longer a novice.
Not to mention how much he understood about the Qingli Sea Cultivation Realm, just crossing it was by no means an easy task.
The total area of Qingli Sea exceeds 900,000 miles.
For cultivators, this distance is not particularly vast.
If a Foundation Establishment Cultivator flew day and night at full speed, it would take more than three months to travel from one end of Qingli Sea to the other.
Theoretically, this could be done.
However, the Qingli Sea is teeming with demon beasts, including Crystallization and Golden Core Demon Kings entrenched within, making the sea region extremely perilous, and with a bit of bad luck, one might also encounter severe natural disasters.
Under such dangers, wanting to cross the Qingli Sea becomes extremely hazardous.
