Shi Feiyang considered that Grandmaster Ha Ha knew that he was no match for him in a fight alone, and that considering his own status, messing with his disciples was also pointless, not to mention it would inevitably lead to a confrontation in the end.
After the incident at Wildman Mountain, Grandmaster Ha Ha indeed had the intention to capture Shi Feiyang's disciples, especially when Shi Zhu was born, and even more so after four of his own disciples were killed, strengthening his resolve.
But he had once "personally witnessed" Shi Feiyang dueling with Elder Kuzhu in the Void Illusion Realm. Elder Kuzhu had kidnapped Mo Zhui, luring Shi Feiyang to Great Wilderness Mountain, only to end up utterly defeated.
Therefore, Grandmaster Ha Ha felt that targeting Lin Han and Shi Sheng would not help him achieve his goal, and might also lead to his own downfall, just like Elder Kuzhu.
