Qin Ruojing's push was so forceful that Chu Ge staggered and ended up sitting on the bed.
Logically speaking, with Chu Ge's capabilities, not to mention a frail woman like Qin Ruojing, even a master at Da Shan's level would find it nearly impossible to make him stumble with a push.
The reason he got pushed over was entirely because he didn't need to be on guard against Qin Ruojing at all, they were standing very close to each other, and he was preoccupied with his thoughts, giving Qin Ruojing the opportunity to do this.
In fact, even when Qin Ruojing reached out to push him, he could have easily maintained his balance, but if he had braced himself and counteracted the force, it might have been Qin Ruojing who ended up falling.
Behind him was the bed, soft and cushioned, while behind Qin Ruojing was the hard floor. If she fell, her pretty head would definitely get a nasty bump.
In such a situation, the choice was simple.
