Ai Cao was bound to a system under the Heaven's Will.
The skills provided by the system allow men to get pregnant, using their bodies as nourishment (upon death) to birth new life.
...
The young man's gaze fell on his own stomach.
Another girl he knew, the one he had once put in a cloth bag, was curled up inside his stomach.
The girls killed their brother, so they dumped them here according to old custom—what did he do wrong? He was just following tradition!
The young man opened his mouth: "Please, don't come looking for me... It wasn't my fault. If you want revenge, don't come after me..."
The mute girl stood silently beside the mugwort.
The old man started berating the young man again. He began by recounting various events from the young man's childhood, accusing him of being unfilial and lamenting his own miserable fate. As he spoke, he even picked up clods of dirt from the side and threw them at him.
A clod of dirt landed on the young man's forehead. A trail of blood appeared on his forehead, and the clod fell in front of him, revealing a small bone underneath.
The young man lowered his head and shook it, begging for mercy.
His belly grew bigger and bigger.
He could no longer support his body. His limbs drooped, and he no longer looked like a human body—his arms stretched out and twisted, digging deep into the soil.
His belly heaved.
He even had the delusion that the nutrients in the soil were flowing through his limbs and becoming nourishment for the... monster in his abdomen.
Sometime later, the old man's cursing stopped.
He was left with only faint breathing sounds, and the young man no longer had the strength to beg for mercy.
Their hearts were pounding in their lower abdomens.
Knock knock, knock knock.
The two girls looked at each other through their bellies, which were almost stretched to the point of being completely transparent.
They smiled in unison, bent their fingers, and drew hard lines on their bellies.
Their fingers sliced open her belly, and it quickly collapsed.
They sat on two dead trees, smiling as they took each other's hands.
They are reborn.
