The Sirius Strike is one of the ultimate forbidden arts of the Starry Unicorn Wolf clan.
The minimum requirement to cultivate it is the Demon Emperor Realm.
This alone demonstrates just how formidable the Sirius Strike truly is.
Once unleashed, it allows the caster to kill opponents across multiple realms.
Although the peak Demon King did not execute the Sirius Strike at its absolute maximum power, it was still enough to make Beigong Yu feel a sharp surge of danger.
He had a strong premonition that this single strike could shatter even his Eleventh-Tier Immortal Artifact-grade physical body.
Almost in an instant, Beigong Yu's mind stirred. Wild, terrifying power and the complete Law of the Blade surged frantically into the Chixiao Ancient Saber.
Fueled by this immense energy, the Chixiao Ancient Saber erupted with a terrifying aura that shook the heavens.
The surrounding void cracked open, leaving dreadful fissures in its wake.
"Go to hell!"
