**The Garden of Origins**
The portal led to a primordial realm where time flowed backward. Rivers of liquid light fed into a colossal tree—the **Worldroot**—its branches holding dying stars and unborn galaxies. At its base stood the **First Arbiter**, a statue of Xiaoyu carved from antimatter.
**Environmental Hazards**:
- **Reverse Entropy**: Wounds healed but aged the body. Lin Shen's crystallized arm regressed to flesh, then to raw, bleeding muscle.
- **Echoes of Creation**: Voices of dead civilizations whispered from the light-rivers, begging for release.
#### **The Serpent's Heart**
The Worldroot's core housed the serpent's true form—a colossus of entwined timelines, its scales etched with the names of consumed realities. *"You return to me, child,"* it boomed, its voice shaking the ground. *"Why?"*
**Xiaoyu's Ultimatum**:
- **Option 1**: Merge with the Worldroot, becoming the Cycle's eternal guardian.
- **Option 2**: Shatter the Worldroot, freeing all trapped realities but unleashing chaos.
- **Option 3**: Reforge the serpent, restoring balance with humanity as its equal.
#### **The Final Bargain**
Lin Shen stepped forward, his body flickering between human and Arbiter. *"There's a fourth option. Let us *share* the burden."*
He plunged his hands into the Worldroot, channeling the Core's energy. The team followed:
- **Bai Ye** linked her photon dagger to the light-rivers.
- **Ghosthand** hacked into the serpent's neural network.
- **Mira** planted her Timelock in the roots.
The Worldroot shuddered. Realities began merging—Neo-Kyo's streets blended with alien jungles and dead stars. Xiaoyu screamed, *"What have you done?!"*
