Having a Secret Technique and not having one were two completely different concepts in terms of combat power.
Zhou Lin did not possess peak Godling cultivation. Earlier, relying on Great Chaos True Power and the Myriad Tribulation Primordial Body, he had only barely possessed the might of a Low-Level King.
With the Dust Frost Sword, he possessed the might of a High-Level King.
After developing a Secret Technique, however, his might quickly rose to the level of a Peak King.
The increase in power provided by a Secret Technique, especially a combined Secret Technique, was truly immense.
Zhou Lin had accumulated profound reserves; it was only his lack of actual combat experience that had held him back. Otherwise, he should have created his own Secret Technique back when he was Transcendent.
After fighting the Black-Robed Man for half a day, the ideas that had existed in his mind finally became reality. The sword and Extreme Point Penetration were a perfect match. After layering the world on top of them, the result could be called flawless.
If Zhou Lin's Great Chaos True Power advanced another level, then the might of his Myriad Sword Domain would truly be terrifying.
"Go."
Under his deliberate guidance, the endless sword light instantly condensed into one. At the same time, the Sword World lost its original stability and became violent.
Boom!
Everything within tens of millions of kilometers shattered. The entire underground cavern shook violently and was on the verge of collapse, ready to bury the Thunder God Hall completely.
The endless sword light condensed into one, resembling the destruction of the world.
Everything was moving toward its end. The energy was boundlessly violent, truly capable of injuring the foundation of a High-Level King. Even a Peak King would be shocked when facing such an attack.
