Chapter 439 - 400: One becomes a God Monarch, only when the Three Flowers gather at the top, one Becomes Immortal!
That is to say, you could use an additional three sets of runes to condense a Chapter, which could be used to construct an Infant God.
Meanwhile, the rune seed condensed from the Lower Three Realms belonged to that rune set, and you could continue condensing it. This could be considered as early preparations for your Primordial Spirit, or even for Crossing Tribulation.
This was how cultivation in the Middle Third Boundary diverged from that in the Lower Three Realms.
In the Lower Three Realms, you only needed to focus on the core Tao Law. However, in the Middle Third Boundary, one needed to gather the three flowers at the top. That is, they needed to condense Chapters of runes corresponding to the Infant God Realm, the Primordial Spirit Realm, and the Tribulation Stage.
When you have a Chapter for the Infant God, the Primordial Spirit, and at the Tribulation Stage, one has three major Chapter systems to their name. That is, the three flowers have been gathered!
So, you didn’t need to condense the Infant God using the core Tao Law, you could use the core system when you reach the Primordial Spirit Realm. In this way, you would have gathered two flowers in advance.
Because of this, the cultivation skills of the Lower Three Realms often took a comprehensive approach where myriad techniques were fused into one single rune.
However, it was the opposite in the Middle Third Boundary. Here, one started to take the extreme route, with three runes forming one Dao!
This meant that, based on the already diverse foundation, one would begin to choose one or several specific directions for extreme development.
That is to say, on the premise that the foundation of the perfector form is strong, the Middle Third Boundary began to stress battle methods, highlighting one direction for in-depth development.
This was because when you are building foundations in the Perfector form, you are developing breadth. When you become a God Monarch, you start to develop depth. When the three flowers meet, that is the moment of Becoming Immortal.
