The surrender of the desert tribes was expected. Although the desert tribes were now under the control of the wolf Soul Kingdom in name, due to special historical reasons, they were relatively independent. Therefore, it was normal for the desert tribes to surrender to Zhao Hai.
However, the wolf Soul Kingdom's surrender was beyond the expectations of the other kingdoms. Although the wolf Soul Kingdom had a good relationship with Zhao Hai, it was not so good that they would surrender to him. In their opinion, the wolf Soul Kingdom's surrender was too fast and sudden.
