They should totally be able to buy flying Soul Tools. 30 Kilometers ins't that far, in "Unrivaled Tang Sect" they had no Problem flying that far even with low ranked flying sool Tools and now it's 10.000 years later so flying Soul Tools should be much better (Energy conserving or with batteries/milk bottles), much cheaper, alot faster, much more readily available and all of them are over rank 50 already. This kind of feels like a bull**** problem.
