After Binding a Time-Space Anchor, He Stayed Behind for Me in the Han Dynasty

I am the living key to the "Quantum Regression" project, the only person who can activate the spacetime anchor. He is my calibrator, and he promised to follow me wherever I went. But during our final test, the System collapsed. To push me back into the safe zone, he was thrown into the chaos of the Han Dynasty. The board sealed the project and declared him "dead." I touch the locator necklace he left around my neck and smile. What you've sealed away is data. The one I'm going to save is the love of my life.
