Zhang Su entered the Cultivation Room.
He opened the first martial skill manual.
This martial skill was a superior-grade technique, an Internal Force-level sword art called the "Posuo Sword Technique."
The Posuo Sword Technique was somewhat similar to the Nine Shadows Sword Technique.
When the sword technique was unleashed, sword shadows filled the sky, making it impossible to distinguish truth from falsehood.
However, the difference was that the sword shadows of the Posuo Sword Technique were basically all illusions.
Only one sword shadow was real.
Yet that single sword shadow came without a sound or trace, and once it struck, it took a life.
It was somewhat like a fusion of the Light Shadow Killing Sword and the Nine Shadows Sword Technique.
Zhang Su carefully compared Blood Qi Realm sword techniques with Internal Force-level sword techniques.
In truth, many of them shared common ground.
After all, Internal Force-level sword techniques had not been created out of thin air; they all progressed step by step.
The greatest difference was the explosive force of Internal Force, which made Internal Force-level sword techniques more powerful.
They might be several times stronger, or even more than ten times stronger!
"The Posuo Sword Technique, Compatibility Rate as high as 97%..."
A strange glint flashed through Zhang Su's eyes.
If this Posuo Sword Technique was studied carefully, it had far too many similarities with the Nine Shadows Sword Technique and the Light Shadow Killing Sword. Calling them branches from the same lineage would not be an exaggeration.
This sword technique's Compatibility Rate with Zhang Su was also as high as 97%, the highest Compatibility Rate of any technique he had encountered so far.
To say that the Light Shadow Killing Sword and the Nine Shadows Sword Technique had not influenced it would simply be unrealistic.
