The black blade was known as Negative Shadow Blade, while the red one was the Positive Shadow Blade. They were twin blades with positive and negative vital energy, which meant that they were inseparable and deeply connected.
And, these two blades were… top grade level one spiritual weapons!
Austin couldn't help but be taken aback, while he was also pleasantly surprised when he read the introduction in the manual.
Cultivators usually classified the spirit weapons into three types: low grade, medium grade, and the top grade.
All types of weapons were divided into five levels.
For a top grade level one spiritual weapon, it was so valuable that even top cultivators from the Mysterious Realm would do anything to get it!
Austin sighed deeply and thought that he wouldn't dare show this level of a spiritual weapon casually in public, even if he had succeeded in refining the Twin Shadow Blades.
There was a saying that the precious jade landed its owner in jail, even though he was innocent! Thus, if someone who was envious of his treasure had targeted him, he was afraid that he might get into trouble.
He went back to reading the secret manual carefully again and tried to understand it.
The core contents of the manual aimed to guide a cultivator on how to refine the two top grade spiritual weapons.
It also contained instructions on how to skillfully use them after their refinement.
Once refined, the two blades could be fused with a cultivator's own flesh and blood and concealed within his body.
When a cultivator fought against an enemy, he could mentally control the Twin Shadow Blades, and the blades would turn invisible and attack the opponent without being noticed.
Austin thought that the predecessors who had refined and created the Twin Shadow Blades were wise.
After se
d unpredictable attack was invisible and impossible to avoid.
He then put away Negative Shadow Blade and released the Positive Shadow Blade. A red light flickered, and the Positive Shadow Blade suddenly appeared, disappeared, and leaped forward in the room. Its trajectory was impossible to identify!
However, he realized that the power of the Twin Shadow Blades' attack came from his own vital energy.
The Positive Shadow Blade emitted an overbearing and robust power, while the Negative Shadow Blade's was soft and sharp. When used together, they formed a set of swordplay array.
Finally, Austin had refined the two blades and formed the Twin Shadow Blades. As for how much attacking power it could release, that depended on the cultivation base of his own vital energy.
After all, the cultivation base of vital energy was always the primary strength of a cultivator.
Austin planned to stay in his house for the remaining three days and try to raise the cultivation base of his vital energy to a higher level.
If he could reach the seventh level of Energy Gathering Realm with his body's abundant amount of vital energy, his vital energy strength would be equal to or even better than Billy's!
