It would take a normal human traveling by carriage almost five months to go from Heavenly Sword Mountain to the Yuan Peninsula. Not only did they have to cross the immense Xia Dynasty, but there were several large landforms and rough terrain that could not be traversed by normal means. After traveling through the one nation, they would reach Song Country, which they would also have to traverse before finally reaching the Yuan Peninsula.
For a Seeker Realm cultivator like himself, it would take just two days to travel that distance.
Of course, he was not alone. Several Human Realm experts were with him. That did slow him down some, but they reached the Yuan Peninsula within three days time.
