This sword technique and the previous Divine Killing Stroke were two different concepts!
Although the Divine Killing Stroke was formidable, it had ultimately become outdated in the realm of law-based combat.
At the level of a Golden Immortal, all combat revolved around laws.
The reason Jiang Xiaobai could kill Golden Immortals—even Taiyi Golden Immortals—was entirely due to his heaven-defying power!
When he unleashed the Divine Killing Stroke with all his might, the strongest attack was not direct but rather the damage it inflicted on the soul!
Very few Golden Immortals' souls could withstand this stroke.
As for the Xulei, needless to say, it naturally carried the attributes of heavenly thunder and could even integrate with the power of laws, easily destroying Taiyi Golden Immortals.
But in front of a real powerhouse—a Daluo Golden Immortal—these two methods were simply inadequate.
