Yun Mu, who had been empty-handed just a moment ago, now held a thin Primordial Energy Sword in his hand. Although the sword was slender and entirely composed of energy, normal people or lower-level cultivators couldn't possibly sense its existence.
However, Lei Yu, the Family Head of the Yin Family, was a master of the Nascent Spirit Stage and had been through countless battles, so how could he not sense the presence of the Primordial Energy Sword?
It never occurred to Lei Yu that Yun Mu, with only the power of the Nascent Spirit consolidating stage, could use a secret technique. Moreover, the intensity of the secret technique was formidable, and the compelling sword qi surprised Lei Yu.
Lei Yu quickly dodged to the side, avoiding a direct confrontation with Yun Mu. and how could Yun Mu's speed possibly exceed that of a Nascent Spirit Stage master? In an instant, Yun Mu's stab hit nothing.
