Su Weifeng, though as tough as iron in constitution, simply couldn't handle being tickled.
Of course, that was when he was relaxed. If he were in the heat of battle, Su Weifeng's muscles would be tensed, and then not only tickles wouldn't affect him, but even a somewhat blunt knife wouldn't be able to penetrate his defenses.
But when Su Weifeng was with Lin Xuanxuan, he definitely couldn't keep his muscles tensed, as that would easily hurt Lin Xuanxuan.
So when Lin Xuanxuan started her antics, Su Weifeng couldn't help but burst into laughter, his hands frantically trying to fend off Lin Xuanxuan's advances as he gasped, "Ha... satisfied, I'm satisfied now."
"That won't do, you were mean to me just now. I'm punishing you," Lin Xuanxuan's slender hands kept dodging Su Weifeng's, as she continued her assault.
