Huiqing proposed a trade, which sounded quite compelling.
After all, the contents of "Nirvana Sutra" had long been memorized; it was no use to Lu Yao anymore. It would be better to trade for a different cultivation technique.
Yu Yanmei immediately sent a message through hidden means, "The 'Dragon Elephant Prajna Skill' is powerful and consumes a lot of Inner Breath, which suits you well. However, its value is not as high as 'Nirvana Sutra'."
In this world, cultivation techniques of Spirit Refinement are unparalleled, nourishing methods are secondary, practice methods come next, and fighting techniques are the lowest.
"Nirvana Sutra" is a method of Spirit Refinement, as well as knowledge of the Out-of-Body Stage. No matter how strong the "Dragon Elephant Prajna Skill" is, it's still a nourishing method, indeed not as valuable.
Lu Yao had a measure in his heart and started to haggle, "Master, the two secret manuals don't seem to be of equal value."
