Duan Ling Tian waited two days before he received the Floating Image Pearls promised by Ku Mu. After that, he was going to leave for the Three Great Sacred Realms. He was not concerned about He Luo's condition after losing. If He Luo managed to recover, it might be a turning point that could propel him to another level.
Duan Ling Tian was not worried about Ku Mu blaming him as well since Ku Mu was the one who suggested this. Ku Mu was the one who asked Han Wang to find a prodigy below the age of 10,000 to defeat his grandson so his grandson would not be complacent and arrogant. Most importantly, Han Wang had reassured him two days ago that Ku Mu did not blame him for what happened.
