Why can't 9Yang break though this door?

In HSDS Zhang Wuji and Xiao Zhao were stuck in the Ming Cult's secret passage and the only way out was by learning Ultimate Grand Shift (乾坤大挪移). But why can he open the door after learning UGS and not with 9Yang?

Because pure strength alone isn't enough to move the door; you need to have QKDNY, which gives you special ways to exert that strength properly, in order to move it. The door was -designed- so that only QKDNY users could open it.

Oh...thank you RWX. I was really wondering about this, lol. ZWJ now has 9Yang + QKDNY...so strong now
