Everyone still remembers the Dragon Kings, but people are beginning to forget Lu Mingfei.
After the Battle of Odin, the once-S-rank student of Cassell College became a dangerous fugitive wanted worldwide. He fled to an apocalyptic sect's sanctuary in northern Siberia, where he reunited with his parents, missing for many years, and heard a heartbeat that did not belong to him.
At the same time, the infant boy known as the "Key," sleeping in an incubator, left the college for the first time. Two hearts, thousands of miles apart, beat in unison for seventeen seconds. Beneath the northern ice, a gate sealed away for millennia began to awaken.
Cassell College, the apocalyptic sect, the mixed-blood families, and Odin's agents arrived one after another. Chu Zihang once again set foot on the elevated highway in the rain. Nono searched for Lu Mingfei in her erased memories, while Lu Mingze waited for his brother to complete one final bargain. As the roots of the World Tree began to grow anew, the names of the dead started returning to the world. But every time Lu Mingfei wielded the power of a king, a part of him vanished from reality.
Beyond the gate were three thrones.
One preserved names, one remade flesh and blood, and one rewrote cause and effect.
Everyone wanted Lu Mingfei to claim one of them: to become the Black King, become a seal, or become the sacrifice that kept the world in order.
But this time, he wanted to choose something beyond the thrones.
He could save the world, or bring the dead back.
The price: no one in the world would ever remember him again.
