Wu Kai believed that Zhao Hai had something to do with Tao Liang's death, but he didn't say it out loud. He didn't have any evidence, and he was in cahoots with Zhao Hai.
Under Wu Kai's lead, the group flew straight to a city that was very close to them. Their speed was very fast, and it only took them two hours to reach the city. It was a small city with a population of less than 500000. However, there was a teleportation array in the city, and they could take the teleportation array directly back to the poison Dragon sect's territory.
