At this moment, Su Tu finally understood why he had been unable to master the Heaven-Flipping Seal, and knew what exactly he was lacking.
Because this ancient skill was not perfect, even when it unintentionally erupted in anger at the Martial Arts Department back then, the Heaven-Flipping Seal was somewhat incomplete.
At this moment, as long as he obtained this lower half volume, he could completely master the complete Heaven-Flipping Seal.
Bringing the brilliance of those gods and immortals back to the world!
But...
Su Tu did not reach out to take the ancient skill, instead, he lightly glanced over it, his expression unchanged.
"Grandpa Tang, the collection value of this ancient skill is not low, and it can fetch a high price if it meets someone who loves collecting."
"You just give this thing away, I feel uneasy holding it."
Seeing Su Tu's calm demeanor, a hint of appreciation flashed in Old Master Tang's eyes.
