More than a year ago, before arriving in the Southern Realm, Yu Ci had already mastered part of the profound mechanism of the Three-Party Primordial Energy. Relying on the fluctuations of the primordial energy within Chengqitian and using meticulous control, he had split off thoughts to send outside.
The first time was a success, yet also a failure. The split thought had been unable to thoroughly shake off the seals of the Three-Party Primordial Energy and had been locked away inside the shed skin and shell, still unable to gain freedom. It was not until it had circulated around and landed in Fan Lingrong's hands that that split thought had truly found a use.
The second time was the remodeling of Gui Yan. Without a doubt, it was an immense success. Not only did he harvest Gui Yan as a useful puppet, but in the ensuing heavenly tribulation, he even pushed that split thought up to the True Person tier.
In the period since, Yu Ci had not continued trying, instead choosing to accumulate his strength.
As the Advancement Demonic Seeds continuously gathered, the impact they inflicted on Chengqitian grew ever greater. The void that had originally been dead and devoid of life gradually gained a few traces of vitality. The operation of primordial energy within grew increasingly lively, and the structure of the Three-Party Primordial Energy that had originally congealed showed a trend of constantly increasing components belonging to Chengqitian and the true realm.
Through the connection between the inner and outer voids, this change was transferred into the thick shell formed by the Three-Party Primordial Energy, also forming a relatively obvious impact. The leeway for Yu Ci's true body to turn and maneuver grew increasingly greater, and the power he was able to wield became ever more formidable.
