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!
