The Nine Heavens Opening Sword was very familiar to Hei Yang, which is why he could recognize it at a glance.
However, he never knew that the Nine Heavens Opening Sword had such an effect, actually allowing the entire planet's beings to make significant progress, comparable to half a planet's advancement.
He even noticed that this transformation was not temporary but continuous.
Although there is an upper limit, future beings will also receive the same benefits and advance.
"Is this what the difference looks like?"
In such a short time, to exert such a powerful effect, it is completely beyond his capability to compare.
"Perhaps only someone like the Lifeless True Saint can truly unleash the real power of the Nine Heavens Opening Sword!"
Hei Yang was unsure whether he felt relief or sighs, but ultimately, he put down the Nine Heavens Opening Sword.
