In some sense, He Tao and Wu Zhe were actually quite decent people. At least, they had both offered genuinely good and valuable treasures to share with their junior brothers and sisters. If Wu Zhe hadn't been too insistent on winning and used shady techniques against the Rain Emperor, Ling Han wouldn't have challenged and humiliated him.
Only after asking around did Ling Han learn that the other four king tiers had all gone out to explore and train.
In reality, the disciples of the Majestic Heaven Sect all had fairly good relationships with each other. If the seniors obtained valuable items during their adventures, they would take them out to share with the newer disciples of the sect. This was a tradition.
When the other four king tiers returned, they would also share some valuable treasures with Ling Han and the others. Such practice was repeated generation after generation, and it had already become a good tradition of the sect.
