Most of Zhao Hai's attention was still on the fake realm. The small sects in the fake realm had almost all been subdued by Zhao Hai's people. Those small sects were the foundation of the realm. Zhao Hai was basically controlling the foundation of the realm. If this Foundation became unstable one day, the realm would be finished.
However, Zhao Hai did not allow the small sects to attack the large sects directly. If they could take over an entire realm without anyone knowing, Zhao Hai naturally did not want to make a big fuss.
Now that the small sects in the fake realm had been integrated by Zhao Hai, he would make a move on the middle-sized sects next. However, this was not so easy. If he did not do it well, he would be discovered by others, and that would cause a big uproar.
