"Mm!"
The Thirteenth Elder nodded, then took the jade slip from Su Mo and examined the martial skill within.
"Nine Heavens Sword Canon!" Seeing the contents of the jade slip, the Thirteenth Elder shook his head slightly and said, "Mo Su, martial skills above the Emperor grade are known as Profound Martial Arts. To cultivate an Emperor-grade Martial Skill, one must first comprehend profound power!"
"Profound power?"
Su Mo asked doubtfully, "What is profound power?"
The Thirteenth Elder pondered for a moment and said, "Profound is still rather distant for you at present, so I will give you a simple explanation first!"
"Profound is the Dao, the Dao of Heaven and Earth. It is said that there are Three Thousand Great Daos between heaven and earth, and Profound is the embryonic form of Dao Rules," the Thirteenth Elder said.
"So that was it!" Su Mo nodded. He had not expected Emperor-grade Martial Skills to involve the Great Dao of Heaven and Earth.
"Master, then what kind of Profound must be comprehended to cultivate this Nine Heavens Sword Skill?" Su Mo asked.
"This Nine Heavens Sword Skill, if I am not mistaken, should be a Cloud Profound Martial Art!"
The Thirteenth Elder said, "If you have already comprehended Cloud Profound, cultivating this martial skill will naturally yield twice the result with half the effort. But if you have not comprehended Cloud Profound at all, cultivation will be rather difficult. You will need to carefully comprehend the Cloud Artistic Conception contained within this martial skill!"
Su Mo's expression turned somewhat bitter upon hearing this. It seemed that mastering this martial skill would be no simple matter!
"Mo Su, your cultivation is still low, so it will be difficult for you to comprehend Profound. This martial skill is not suitable for cultivation now.
