Yu Wudi agreed to take Ling Han to find his "friends," not just because he could not bear with such torment, but because he wanted Ling Han to walk out so that others could see him. This naturally would alert the authorities of the martial academy, and they would send someone to save him.
He was certain that Ling Han had to have reached the Pseudo-Heavenly Venerable Tier, or even further than that, and that was why he could take him down with a single blow.
F***, a Heavenly Venerate was being a bully, so the martial academy would definitely interfere in this matter.
Very soon, they arrived at the foot of a mountain. This was where one of Yu Wudi's friends lived. That man's name was Cheng Feiwen, and he was also a Ninth Heaven Celestial King, but he did not have a Heavenly-Venerable-Tier elite among his ancestors.
This small clique was led by Yu Wudi because only his father was a Heavenly Venerate, and a Second Tier Heavenly Venerate at that.
