Shi Lang did not know about the things happening outside after the incident with the Zhu Family. He was immersed in cultivation and wanted to reach the peak of the Immortal King realm. It was said that all the Immortal Kings were allowed to participate. However, that was too broad of a spectrum.
There were many rules that the people did not mention in detail. Well, the initial assessment was when the people thought the tournament had begun because not everyone managed to ace it. There have been many deaths because the cultivators were stubborn and did not give up.
Tian Long had told Shi Lang about the difficulty level, and thus, he was preparing the best he could. Yun Xue was also the same; she was at the edge of ascending to the Immortal Queen realm. The tournament had just been held two days ago, and Shi Lang had yet to escape his seclusion.
