"In this age, according to Chinese traditions, any secret knowledge that helps people promote all the way from LV 10 to LV 16 can be called sutra, which indicated its qualified, dignified position."

Instead, they were the far-ancient cultural product that people discovered in the underground relics. That's why cultivation methods above LV 10 are very precious!"
Lan Yunxi continued to explain as Zhang Tie gradually understood the world of cultivation above LV 10. At the same time, a question appeared in his mind.
"Now that such a secret knowledge is so precious, why have I encountered many human fighters above LV 10. Have all of them gotten the precious secret knowledge?"
