Arc 4Ember Base’s Last Stand
Tiandao faced the Star Envoys’ assault on Ember Base, defeated the invaders, and stayed behind as the base self-destructed so Caroline and the Starborn could escape. He survived in a Black Calculation Pod, then began preparing to claim the Miracle Stone: Law.
- Caroline gave Tiandao a Deep Blue Sound necklace before they left Trillan, and the group returned to Ember Base, where Tiandao insisted on taking a dangerous mission from Doctor.
- Four Star Monuments summoned a Beast Tide and triggered Star Core Resonance, so Tiandao, Yun Meng, Gang Yan, and the others split up to destroy the Monuments while Chen Xing and her group defeated the western one.
- After destroying his Monument, Tiandao returned to Ember Base and found an Association Star Envoy raid underway, so he activated the lethal defenses and released the Star Beast test subjects into the maze.
- Tiandao fought Benjamin and the invading Star Envoys, killed Benjamin with a hidden Black Azure, and continued protecting the Quantum Hub despite being blinded and gravely injured.
- Tiandao ordered the Starborn to escape aboard the Quantum Shuttle, then connected himself to Glimmer while Caroline awoke and found his prerecorded message.
- Caroline tried to save Tiandao through Mechanoid modification, but Tiandao activated Protocol No. 3, sealed her memories of him, and sent her to the shuttle before Ember Base exploded.
- Doctor said Tiandao had changed the future, and a camera revealed him asleep in a Black Calculation Pod on the ocean floor.
- Tiandao obtained Hyper-computation through a character-background modification, combined it with Vector Control to erase his presence, and tested an energy-intensive Eight Gates Formation.
