"That's right, the Lu family also has a more important secret manual in their line of heritage, the 'Seven Apertures Spirit Secret'."
Zhou Sui's eyes showed a flash of intensity.
Without a doubt, aside from the second-stage Alchemy Heritage, the most important heritage of the Lu family is the 'Seven Apertures Spirit Secret'.
This was the crucial reason why Lu Hongran, the ancestor of the Lu family, rose to prominence and advanced to become a Foundation Establishment cultivator even though he was a loose cultivator with only a fifth-grade spiritual root and without a sect.
It was said that Lu Hongran used to be just an ordinary scholar in a mortal dynasty.
By chance, he slipped off a cliff and accidentally entered a cave abode.
There, he happened to encounter a fallen high-person and obtained his heritage.
The most important of these was this 'Seven Apertures Spirit Secret'.
This was a Soul Secret Art for cultivating the power of the spirit, incredibly profound and deep.
