Three hundred years ago, the high-dimensional world-eating tribe tore a dimensional rift at the boundary between heaven and earth. Lin Cangya, the boundary keeper, forged the Gate of Taichu - a dimensional crack repair device to guard for generations. Three hundred years later, Lin Zhengtang, the 18th generation boundary keeper, lay in a sealed coffin. Before his death, he gave Sun Linhui his last words: Go to Sujiabao to be a son-in-law, get the boundary-breaking cone, and come back to guard the gate.
Lin Hui heard three knocks in the coffin - those were not his grandfather's last words, but the whispers from the Gate Devourer through the corpse. He is not a rescued orphan, but a chosen guardian. His mother was trapped on the other side of the crack, and his father had been waiting for him at Wild Wolf Slope for twenty-eight years.
After joining Su's family, Lin Hui found the same boundary-keeper blood mark on Su Wanqing, the eldest daughter of the caster. The two bloodlines, separated by three hundred years, will reunite in their generation. The Shattered Cone has two sides: the key on the front and the lock on the back. Use it wrong and he'll be trapped in darkness forever.
Lin Hui lay in the coffin and stayed there for two thousand days. Su Wanqing came every day, talked to the coffin, and carved marks on the tree. The lamp in the copper coin never goes out. The crack was eventually sealed, but the mission of the boundary guardian was not to guard the crack—it was to guard the family.
