As for the routes, Zhao Guang can completely relax, allowing other ocean powers to take control while he only needs to intervene occasionally.
After all, the route is really too long, passing through many ocean territories. If he tries to control it all, not only would there not be enough troops, but complete control would not be an easy task.
It's better to directly use intimidation combined with incentives, letting those ocean forces help him control them more effectively.
However, there are three places he must control, which are the coastal areas of his own territory.
Including the coast of the Xuanwu Kingdom, the coast of Xuanwu Territory No. 2, and the surrounding area of his Land of Faith.
The Land of Faith covers the most sea areas, so this place also needs the most defensive power. Thus, the Thunder Dragon Flowers frequently come into play, having already been planted abundantly around the major islands.
