The moment the whole White Jade Small Sword appeared, a tremendous oppressive force emanated from it, causing the space to rupture under its massive pressure, unable to endure the inadvertent energy fluctuations it emitted.
Furthermore, given Zhang Xiaohao's current cultivation, he was not yet at the Divinity Transformation Realm and was unable to wield it!
Unless relying on one's royal bloodline talent, there's absolutely no possibility; additionally, even if he used the Xuantian Jiao Sword through the king's bloodline, it can only be utilized three times! After those three times, using the Xuantian Jiao Sword again would lead to severe damage, so Zhang Xiaohao wouldn't use those precious opportunities unless absolutely necessary.
Anyhow, it's just digging a cave, if using such a precious opportunity recklessly, then it's better to directly wield the Xuantian Jiao Sword to slay the three-headed Monster Fish Demon Beast, saving all the trouble.
