The Underworld King Blade was one of the Six Treasures of the Underworld that he had obtained in Nine Nether City.
When he saw Dark Nether Old Ancestor perform Dark King's Three Kowtows, he immediately thought of the Six Treasures of the Netherworld. However, he did not know what treasure to use at that moment because none of the treasures had been refined except for Crimson Light Heavenly Monarch.
In times of crisis, he could not care about anything else. He was like a drowning person grabbing at random, desperately trying to find a cure.
Thinking of the Underworld King Blade, he summoned the Underworld King Blade with his divine sense. The Underworld King Blade went straight for the arm of the three kowtowing Underworld Kings.
The aura of the two forces were exactly the same but Li Lingtian had no idea at that moment. All he could think about was how to withstand the terrifying arm. If he could not withstand the attack, he would be destroyed.
"Crash."
