At this thought, Chen Nianzhi fell into contemplation once more.
At his current stage, the Primordial Chaos Indestructible Body had already reached a bottleneck, and there was yet another barrier before it could advance further.
This bottleneck could not be broken through with resources alone. After refining a great number of Six-Transformation Immortal Pills, the Primordial Chaos Indestructible Body's source had become exceedingly abundant.
Yet this overabundant source power had also made the Primordial Chaos Indestructible Body's foundation somewhat unsteady. It still needed to be tempered into pure source essence.
There were two methods to temper the physical body. The first was to spend time slowly polishing it.
With Chen Nianzhi's current foundation, so long as he spent a million years or so continuously using the Primordial Chaos Limitless Law to temper himself, he would sooner or later enter the major completion realm as naturally as water flowed downhill.
Beyond that, borrowing external forces to temper the body could also hasten the process.
At this thought, Chen Nianzhi could not help thinking of the Abyss of Guixu, but after a moment, he still shook his head.
The Primordial Heavy Water within the Abyss of Guixu was not domineering enough. Using it to polish the Primordial Chaos Indestructible Body would likely require three hundred thousand years to reach major completion.

Seeing this, Jiang Linglong pondered and said, "If Husband wishes for the Primordial Chaos Indestructible Body to reach major completion,
