Several more months passed after the sect-protecting formation was laid down.
Li Ping refined another third-tier top-grade formation, this one specifically designed to block probing divine sense.
But when he drove all the formation banners underground and activated it, he discovered to his surprise that no unusual phenomenon appeared before him, nor did any creation qi surge out of the spirit vein.
Only then did he understand why the Formation Dao-related effect of his creation magic power was called "Vein Creation."
The creation qi produced when a formation took shape did not come from the formation alone, but from the formation and spirit vein becoming one.
After all.
Without a spirit vein supplying spiritual qi, a formation could not display its corresponding power at all.
In other words, a given spirit vein would only produce creation qi the first time Li Ping laid down a formation there. Subsequent formations would produce none.
This put an end to Li Ping's idea of repeatedly farming formation-related creation qi.
"As expected, it wasn't going to be that easy." Li Ping shook his head slightly.
Fortunately, although he could only draw creation qi from the same spirit vein once, the grade of the creation qi produced was also tied to the spirit vein itself.
Thus, although the grand formation he had laid down was only third-tier top-grade, the creation qi he obtained was fourth-tier low-grade.
After absorbing a portion of fourth-tier low-grade creation qi, the Vein Creation effect had also begun to take shape.
He could head to the cultivation region Ten Thousand Souls High Person had slaughtered, lay down a formation there, and cultivate while using Vein Creation to improve the grade of its fourth-tier spirit vein.
Of course, raising a fourth-tier low-grade or fourth-tier middle-grade spirit vein to fourth-tier top-grade was not
