The instant Xu Jingming unleashed his Slaughter Domain, the entire plaza fell into a terrifying silence.
The blood-red domain, thirty thousand kilometers in diameter, resembled an expanding crimson star.
Through the Virtual Universe projection, it radiated a chilling murderous aura that made souls tremble!
"What level of proficiency is this?!"
An Eight-star General cried out in a low voice.
Everyone had witnessed the power of the Slaughter Domain through Lin Qianxue.
Suppressing six opponents of the same rank within a hundred-kilometer radius was already considered a miracle.
But Xu Jingming's domain... had a diameter of thirty thousand kilometers!
Three hundred times Lin Qianxue's!
"It's definitely beyond advanced proficiency!"
"How could an advanced-proficiency Slaughter Domain possibly reach this scale?"
"Could it be master-level? Or grandmaster-level?"
"..."
Cries of shock and sharp intakes of breath rose one after another.
Beginner, intermediate, advanced, master, grandmaster, and perfect were the different stages of combat skill proficiency.
Advancing through each stage was extraordinarily difficult!
As for improving one's proficiency in the Killing Combat Method, it required an extremely deep understanding of the essence of slaughter, along with the accumulation of vast amounts of killing intent.
When Nine Swords Sovereign created this technique, even he had needed a full thousand years to progress from advanced proficiency to perfect mastery!
But now...
"No."
High in the sky, Nine Swords Sovereign slowly spoke.
A clear trace of shock appeared on his face, which had always been as stern and cold as ancient ice.
His voice was not loud, yet it exploded like thunder in the depths of everyone's souls. "It is perfect mastery."
"Perfect mastery?!"
"How is that possible!"
"Perfect mastery in three months?!"
The plaza instantly erupted. Countless gazes locked onto the black figure enveloped by the blood-red domain in the Holographic Projection.
Their eyes were filled
