The wolf Soul Kingdom had been unified once again, and yakbu had also given the titles of King to the leaders of the large tribes. Although those large tribes were still under his command, they were very independent. The wolf Soul Kingdom was now more like an allied country, not an Empire.
However, Zhao Hai believed that with yakaban's ability, slowly unifying the wolf Soul Kingdom wouldn't be a big deal. Yakobu had the means to do so.
At the same time, Zhao Hai also knew that yakobu had also sent people to kill dugu Xiong and the others. However, he was a step later than Zhao Hai. Dugu Xiong and the others had already been killed by him. Naturally, the people that yakobu had sent out could not be found.
