The first step is always the hardest.
Jason Morgan led the ships of the Fox Moon Star Domain and basically mastered a relatively safe way to pass through the Star Realm Tunnel in the subsequent tests.
A church filled with the Emperor Divine Statue and inscribed with the Holy Words, equipped with the National Church's choir, and supplemented by a Blessed Star Realm Protective Field generator, forms the most basic configuration.
Equipped with enough Blessed Holy Water, the ship has a 'clean-up team' to constantly combat corrosion marks and eliminate the evil entities invading the vessel. This is what needs to be done on top of the previous setup. Only when the choir, church, and Blessed Star Realm Field are all in place can the phenomenon of evil presence and even invading Evil Demons be weakened to a level that can be fought against, allowing the guards on the ship, using Holy Water, to destroy the enemies with mortal bodies.
