Wang Dadong did not turn into a beast, he just wanted to change Mo Xiaoxiao's size a bit.
Mo Xiaoxiao's height couldn't be changed because it would be extremely painful, to the point she wouldn't be able to walk.
So, changing just the appearance wasn't secure enough; there was a chance Chu Manhe would recognize her.
If they could change the size there, it would be much safer.
Wang Dadong let Mo Xiaoxiao choose between enlarging and reducing her original size.
Mo Xiaoxiao naturally chose to enlarge.
No woman would be foolish enough to choose to downsize, right?
In fact, for Wang Dadong, enlarging Mo Xiaoxiao was much easier than reducing her size.
Because he only needed to inject some Inner Strength to enlarge Mo Xiaoxiao by one or two sizes.
To shrink it would be much more troublesome.
When Mo Xiaoxiao stood in front of the mirror, she was instantly stunned.
