Han Sen was suffering beneath the Sky Palace text. He could not focus on anything else, and he did not hear what Thousand Feather Crane had said to him.
Thousand Feather Crane could see Han Sen suffering, though. And without thinking, he moved to grab hold of him.
"Relax, it is okay." Thousand Feather Crane smiled as he helped Han Sen.
The feelings around Sky Palace were strong, but Thousand Feather Crane possessed the blood of the Sky. He was born there, and he was immune to that power. He held Han Sen with ease, because he felt nothing. It'd be so light, even if Han Sen was getting crushed.
Thousand Feather Crane saw that Han Sen was continuing to walk forward, and so gave him his own arm to hold and support him. If he fell, Thousand Feather Crane would use his own strength.
