Leaving the Royal City of Western Empire, Long Chen flew towards the Northern Empire. As he had all the maps already, he didn't need to be concerned about being lost.
The only thing he was concerned about was the location of the Dark Tribe. According to the markings on the map, the Dark Tribe lived near the Royal Palace of the Northern Emperor.
This was what made the Dark Tribe so sate. They not only had their own warriors protect themselves, but they also had the support of the Royal Palace.
In case someone even dared to attack them, they were to face the wrath of the Royal Army even if they survived the onslaught of the Dark Tribe.
That was like fighting on two fronts to take out one enemy. Fortunately, it could have been avoided by taking out Dark Tribe before the information of this attack reached the Royal Emperor. It was the hardest to do.
