Spirit-Absorbing Grand Magic, Water-dissolving Formation...
It was a method that relied purely on water spirit energy to activate the Spirit-Absorbing Grand Magic, then condensing into a ball of pus that had the ability to absorb spirit energy and absorb the spirit energy of cultivators.
The Water Sect Master clearly remembered...
This special method of using the Spirit-Absorbing Grand Magic required profound mastery of both the water spirit energy and the Spirit-Absorbing Grand Magic before one would be able to use it.
As for the master of the Water Sect, he had been cultivating the water spiritual power for nearly 50 years and the Spirit-Absorbing Grand Magic for nearly 20 years...
Yet he hadn't cultivated this technique to its peak.
Therefore, he didn't know how to perform this technique.
Moreover, he had always subconsciously felt that... This technique didn't exist.
