Book of Holy Demons

Lin Yan was taken aback.

It... it had run off with him...

From Qing Cang's tone, he could sense no great anger or frustration—rather, there seemed to be a trace of something like resentment. Lin Yan had not expected that.

"You have spent these years studying the Panwang Mountain lineage inheritance, so you should know something of this," Qing Cang explained. "In the Ancient Civilization, when certain incomparably defying heaven Super Existences sought suitable inheritors for the ultimate skills they took pride in, they would expend tremendous effort to refine a 'secret technique treasure.'"

"A secret technique could contain a spirit."

"Those capable of refining secret technique treasures were all Super Existences of the Ancient Civilization. And the 'secret techniques' worthy of their effort in refining such treasures had incomparably demanding cultivation requirements."

"A secret technique with a spirit would naturally choose a truly suitable master. If other experts attempted to seize the secret technique by force through their great strength, they could only fail. Moreover... as long as this secret technique treasure had not acknowledged an owner, even an expert like the Ancestor would find it difficult to destroy."

"Our Panwang Mountain lineage inheritance, for instance... I personally select inheritors, and the Mountain Master Token ensures that information about secret techniques cannot leak. Naturally, there is no need to refine secret technique treasures. But the origins of the 'Xuan Yuan Technique' are special. It is an ultimate skill passed down by that invincible existence, and so it uses this method of a 'secret technique spirit.'"

Lin Yan nodded slightly.

Weapons had spirits, like the "Origin" of the Chaos Golden Wings. Worlds had spirits as well, like Qing Cang of the Heavenly Realm Stone. Secret techniques likewise possessed spirits.

However, merging a secret technique into a spirit was extraordinarily demanding.
