Chapitre 439: 439. The Arbitrator

Once again, they took the Tame River, but this time they rode a grandiose ship that belonged to the King. It used multiple wizards to move fast upstream. The Sand City was not too far away, so by evening, they neared the majestic walled city situated beside the point where the Tame River and Snake River intersected. 

Using elemental earth wizards, an artificial moat was formed from the Tame River to the Snake River behind the Sand City, which instantly gave the city protection from all around. But, Sand City had limited area, so a new city was made on the other side of the moat, called Gravel City, and on the other side of the Snake River, there was the Blessed School Of All Arts, where people of all social rankings were taught a talent.
