I'm a Spy in the Divine Clan

His name is Jiang Yan, the most successful human spy in history. Three thousand years ago, he was transformed to have a divine race physique and infiltrated the divine race's imperial capital. Three thousand years later, he had risen to become Marshal of the Seven Luminaries, commanding a powerful army and enjoying the emperor's deep trust. The emperor even treated him as an adopted son. No one knew his true identity. Even he had almost forgotten it. Then one day, a secret order sealed away for three thousand years suddenly activated: “The Endgame Plan is underway. Topple the divine race's leadership within three months.” He should have been delighted. He should have carried it out. But when he saw the adoration in his divine-race disciple's eyes, the life-and-death trust of his comrades, and the emperor's tender, fatherly concern, he realized he could no longer raise his blade. Worse still, the truth behind the so-called “Endgame Plan” was to sacrifice half the population of both races and forge “peace” in blood. So he betrayed both the human race's orders and the divine race's trust. So both sides hunted him down. So he chose a path destined to be lonely He would help neither humans nor gods. He would help only those who did not want to die anymore.
