In short, the Four Heroes of the East Sea weren't fools. After spinning and fighting in circles for over a dozen rounds, they realized that not only couldn't they break defenses or bodies, they couldn't even tear clothes, realizing they were being used by others for training like wooden dummies. They immediately wanted to retreat.
However, although Tie Dan's fist technique wasn't as exquisite and exceptional as Cang Song's, in this close combat, it would be embarrassing to let these Divinity Transformation juniors escape from his hands. So he swung his fists in counterattack, and with a slight use of fist power, forced the Four Heroes of the East Sea to focus fully, needing to use energy transfer to protect themselves, disperse cultivation, and reduce power, not daring to easily retreat for fear of exposing their backs and getting blown away by a punch.
