Hiss!
Xia Feng couldn't help but take a deep breath of cold air.
Although he wasn't certain if the Spirit Light Flying Boat was an Ancient Divine Artifact, he knew that it was made entirely of special materials.
Moreover, with the coverage of Star Power, it could withstand attacks from a Profound-tier Martial God without any effect.
Even for an Earth Tier, or even Celestial Tier Martial God, breaking it would require some time.
Xia Feng now actually felt that using the Heaven-Burying Sword to smash it with one strike was conceivable, indicating just how powerful the Heaven-Burying Sword was.
He roughly used his Great Dao of Celestial Sword to refine the Heaven-Burying Sword once, barely incorporating it into his body.
It was indeed barely incorporated into his body; he could feel that the Heaven-Burying Sword was somewhat reluctant, perhaps he needed to refine it more carefully with the Great Dao of Sword, but he didn't want to cultivate in such an environment.
