The erasure was no longer a abstract threat; it was a physical geometry. Haoran had become a literal silhouette, a two-dimensional boundary line separating the ravenous hunger of the womb from the collapsing framework of the outer universe. Without silver to give structure or obsidian to provide mass, he existed purely as a localized law—the law that Yuxiao must not fall.
But the Twin Primordials were indifferent to the geometry of their parents. Inside the bleached, white void of the horizon, the amniotic pressure within the Womb-Gate began to boil. The Iron Prince and the Starlight Princess were growing larger, their metaphysical volumes expanding at the "Speed of God."
The pale light of the room began to bend, warping into a massive, inward-facing funnel toward Yuxiao's midsection. The twins were no longer just drinking elements; they were consuming the very Concept of Proximity. Anything that was close to them was being compressed, pulled into the fetal gravity to form their external skin.
Yuxiao screamed, a sound that carried no audio but tore through the remaining Threads of the Absolute. The compression was collapsing her internal space. Her ribs, her organs, the very concept of her physical interior was being flattened to make room for the expanding heirs.
"The space... there is no room left inside me for them," she gasped, her eyes turning into empty, silver-rimmed mirrors reflecting the countdown. "They are expanding faster than the timeline."
Haoran's silhouette moved, pressing itself entirely against her back. He could not speak, and he could no longer feel the touch of her skin against his, but he possessed one final, foundational layer before his core concepts were reached.
Using the Threads of the Absolute like a needle, he sewed his own flat, two-dimensional shadow directly into the perimeter of Yuxiao's body. He became an external chassis. He volunteered his own boundary to serve as the new wall of the womb, absorbing the crushing outward pressure of the twins' expansion.
The impact was instantaneous. The silhouette of Haoran cracked, jagged lines of pure, unformatted white light splintering across his dark form as he took the strain of the children's growth. His sacrifice stabilized Yuxiao's internal space, giving her room to breathe the thin, conceptual air of the dying world.
The countdown, etched into the cracking surface of his own shadow-chest, shifted: 456 chapters remain.
