The Shallow Dimension of the Boundary Sea.
Qin Heng's avatar had not remained motionless. Instead, it traveled between the True Universe and several nearby Pseudo-Universes, familiarizing itself with the Boundary Sea's environment.
He observed the environmental characteristics of regions both near and far within the Boundary Sea, calculated the differences in arrival times for each crest of the Boundary Sea Tide, and at the same time nurtured the seeds of the Dao established by himself and Dong Huaiyue, allowing them to quietly take root and grow within the nearby Pseudo-Universes.
With his main body and avatar serving as temporal reference points, Qin Heng calculated the cycle of the Boundary Sea waves.
Their width could span the combined forward depth of more than three hundred Pseudo-Universes—three hundred "steps" wide.
From rise to fall, from the highest point to the lowest, it took more than thirteen thousand Earth years. Then came a tranquil period of roughly twenty-nine thousand Earth years before the next wave arrived.
One wave alone took over forty-two thousand Earth years. One could imagine just how lengthy the full tidal cycle was.
According to Cleaner No. 2, the tides of the Boundary Sea had two directions. One spread outward from the center of the Boundary Sea, while the other reversed course and drew inward.
Whenever the outward-spreading tide—high tide—arrived, all universes would breathe open, drawing in the energy of the Boundary Sea Tide and gaining growth.
During the reverse tide—low tide—the True Universes had to seal themselves off, preventing Cosmic Energy from being drawn away.
Such a cycle required at least several hundred thousand eras. Many True Universes did not even have lifespans that long before they were destroyed by external forces.
At present, the Boundary Sea was in its high-tide phase. Energy from the Boundary Sea Tide continuously
