Before using "Heavenly Heart Tribulation," Shi Xiaole couldn't be sure of its actual power and could only estimate a rough idea, believing that even if he were surrounded by three top-notch Heaven Realm Martial Emperors, he would be able to escape in the quickest manner possible.
Seeing how he had successfully inflicted heavy damage on the Flame Sun Great Emperor, Shi Xiaole knew he had underestimated "Heavenly Heart Tribulation," or rather, he should say he had underestimated the power boost from the Great Achieved Heart Sword.
After all, this was a realm that surpassed most of the Heavenly Realm Sword Emperors—how could it be taken lightly?
Without any hesitation, Shi Xiaole seized the opportunity to press his attack, not giving the Flame Sun Great Emperor a moment to catch his breath, and killed toward him once again with boundless sword momentum.
"Relying on a petty surprise attack, how dare you act so ferociously, young one!"
