In fact, the Beastman Empire on the other side did not hold out for long.
After a massive slaughter of the Beastman Empire's resistance forces, that day, the remaining royal family of the Beastman Empire collectively sought out Fang Jie, admitting their defeat and recognizing Fang Jie's rule.
From that point on, the three strongest native forces of the North were finally uprooted by Fang Jie.
"Now, only the demons of the North remain, and they are something I must deal with next," said Fang Jie thoughtfully, but he didn't plan to deal with the demons on a large scale for the time being, and would wait until their current frenzy had subsided. However, the people left behind by the two empires were not as easily handled as the Dragon Clan.
Dragon Beasts worship the strong, and as long as you are much stronger than them, they won't rebel.
