After spending a few days, the many Creators and Deity Emperors finally managed to drag the ship all the way to the King's palace before they all scattered back to Azure Dragon Gate. The castle walls around Azure Dragon Gate were crushed by this ship when it was salvaged, hence, they had to repair the damage with the star sand in the river.
Apart from that, the Deity Emperors, Creators and even Imperial Emperors had to shower their blood onto the compound, carving their totem patterns onto the walls, creating totem talismans and formations before linking the Dao totem patterns with those from the other walls in order to have the newly built walls be strong enough to withstand the star waves.
If not, they wouldn't even be able to withstand the impact of the waves, let alone an invasion.
