Su Yuan was originally an unknown young man from a corner of southern Xinjiang. He was born in troubled times and witnessed his family being exterminated due to a "secret contract of immortality". Everyone in the world believed that immortality was a lie, but Su Yuan knew that what was contained in this deed actually pointed to the "soil of rest" that was left behind eons ago. He vowed to explore the ruins of the world and embark on a journey of exploration that defies the will of heaven. However, immortality is not false, and immortality is not a blessing. Every time you get an opportunity, you will lose a true love; every time you break a secret barrier, you will see the subtleties of human nature. On the road to pursuing eternal life, Su Yuan kept making choices: for revenge or for transcendence? Should he stick to his true heart, or become an indifferent zombie? In the mountains and seas of Kyushu, secret skills are circulating, old friends and new enemies are all here because of obsession. In the end, can Su Yuan realize the true meaning of immortality in the intertwining of desire and fate, or will he become the legendary third passer-by lost in the world? This book uses the search for deeds as the thread and the human heart as the mirror to describe the desolation and tenderness of the immortal road, subverting the meaning of "immortality".
