Your AV is looking very weak... very dehydrated...
May be before re-rooting, it would be nice to soak it in water for at least 4 hrs (adding some 活力素 will also help) so that the plant can be re-hydralise to some degree?
Please remove all flowers, because flowering actually takes up a lot of engergy + water... making your plant even weaker than it already is...
by removing all flowers, you're helping the plant to concentrate its remaining engergy (which doesn't look like very much to me...) to re-root ^^
Best of luck with your plant
