Chen Jichuan sensed that his foundation was solid, and his insights into Heaven and Earth were deep, yet he was still slightly short of achieving a breakthrough.
Indeed.
In the final century of his current lifespan nearing its end, he returned once again to Sumeru Immortal Sect's Seven Treasures Pond, using the Eight Dharma Water to re-cultivate his Divine Transformation Realm.
It had been seven to eight thousand years since the Eight Dharma Water was completely depleted back then.
Over the years, the Seven Treasures Pond had accumulated a considerable amount of Eight Dharma Water.
Chen Jichuan used it to re-cultivate, while also deriving new magic and cultivation techniques in passing.

Afterwards, he began deriving the 'Najia Divination Method.'
