rLDA: reverse LDA -- pulling, instead of pushing, "through the air" without physical contact.
Here's what Qiu Qianren did:
但见慈恩左掌拍出,右手成抓,同时袭到,两股强力排山倒海般压了过来,待欲退后逃避,却那里还 来得及?
黄蓉、武三通、耶律齐三人不约而同的纵上。三人于一瞥之间均已看出,慈恩右手这一抓虽然凶猛,但远不及左掌 那么一触即能制人死命,因此三掌齐出,都击向他左掌。砰的一声,四股掌力相撞。
慈恩嘿的一声,屹立不动。黄蓉等三人却同时倒退数步。耶律齐功力最浅,退得最远,其次则为黄蓉。她未稳身形 ,先看女儿,只见郭襄已给慈恩抓住,郭芙却兀自呆立当地,惊得慌了,竟然忘了躲闪。
The reason I think Qiu Qianren may have performed rLDA, is how did he get ahold of baby Guo Xiang? Guo Xiang was in Guo Fu's hands. Qiu Qianren used both hands to attack Guo Fu. His right hand palm was stopped by Huang Rong + Wu Santong + Yelu Qi, and didn't hit Guo Fu. But if his right hand didn't hit Guo Fu, it should mean his left hand didn't reach Guo Fu either. If his left hand didn't hit Guo Fu, and he still managed to snatch baby Guo Xiang out of Guo Fu, that must mean the snatching was performed "through the air".
