To be honest, if it was simply a matter of heading to the Western Continent, it wasn't too troublesome. After all, with the Academy setting the precedent, the inter-connected nature of the five continents wasn't too bad, and even now in a general 'war time' there were still plenty of boats and methods for ordinary people to head from one continent to another.
For the various sects, there should also be teleportation formations that had been set up! Although, with Di Tou's current cultivation that wasn't really a feasible option. The bigger issue for Di Tou was how fast he could get there, and also how inconvenient it would be.
Taking a boat would inevitably take a few days or weeks, depending both on when the boat set off, as well as how fast the boat travelled and what stops it had to take. Then when he arrived at the Western Continent, there was still a matter of actually getting to a major city so he could orient himself and then go find the Realm Fractures!
