The Void Brain system and the Demon Rune system... let's call them that for now.
From Ronan's perspective, there was little point in deliberately distinguishing between them. No matter how their principles differed, as long as both could be used by him, that was enough. Combined, they expanded into domains neither could reach alone. They could ascend or descend, climb to heaven or enter hell—what was wrong with that?
What truly mattered was how to combine them, as well as the technical problems involved in practical application.
There was one very practical issue: reason had a scale, while sensibility—or emotional instinct—was difficult to measure.
It was like Ronan's class half a month ago. He could teach the same knowledge to over a thousand people at once, progressing from shallow to deep, then build the complex and grand Blood Intent Ring Fortress on that foundation. Granted, the standards of the mental level were difficult to grasp as well, but the Fortress's continuously layered Configuration design cleverly solved that problem. As those thousand-odd people kept adjusting to one another, their understanding and recognition of the Fortress's structure gradually converged, forming a greatest common denominator. That was precisely the advantage of reason.
In this regard, emotional instinct possessed an irreparable flaw. It had too many variables and was too unstable. It was difficult to apply rational standards to it, and once a standard was applied, emotion could no longer be called "emotion."
Most fatally, when the Emotional Turbid Current gathered, it could easily head toward extremes. Extremes meant losing control, meant the end of change. For any dynamic system, heading toward an extreme was a disaster.
Like the Great Living Area covered by Silent Thundercloud, where accumulated fear could crush a successful man like Yue Qi into breakdown. The effect looked quite good,
