The cosmic membranes of other universes were only a few hundred million light-years thick, accounting for less than one-trillionth of their total diameters. Yet in the Tidal Gyre Universe, the universe's internal space was the part that accounted for one-trillionth of its total diameter!
The Heart of the Sea was the true internal space of the universe. That cosmic ocean from before lay within the cosmic membrane, and those fluids were Chaos Matter within the membrane layer!
At 1.74 million years old, you became obsessed with cultivation.
Besides the spiritual root system you had cultivated before, you also tried different paths of cultivation in other universes.
For instance, there was a Carrier System that did not rely on spiritual roots. One could cultivate it directly, and every realm had fairly classic Foundation Establishment and Core Formation methods, divided into Heavenly Dao Foundation Establishment, Immortal Grade Golden Core, and so on.
The Dao Foundations and Golden Cores forged through these methods were called carriers.
The base value of this system was very low. At the initial Qi Refinement stage, the system's Dao Seal Quality was only 1 point—extremely weak.
When you underwent inferior Foundation Establishment, the system quality would fall to 0.9. From then on, you would be stuck at Foundation Establishment Early Stage, your cultivation might even become unstable, and you would never advance another inch for eternity.

With High-Grade Foundation Establishment, the system quality rose to 3 points, while Heavenly Dao Foundation Establishment raised it to 5 points.
In this system, every realm required one to raise Dao Seal Quality to the corresponding level through methods such as Foundation Establishment before one could break through.
For example, system quality had
