The heavenly pillar collapses, the Weak Waters flood the world, and the prehistoric world enters its darkest age.
Lu Chen transmigrates into this world and becomes a corpse floating in the flood.
He assumes he has entered the familiar world from mythology textbooks: Nuwa is about to mend the heavens, the Three Pure Ones have yet to become saints, and humanity is barely clinging to survival.
Then the ancient book in his arms, titled The Fragmented Scroll of the Epoch, begins writing by itself:
"The Ninth Epoch has officially begun."
"Host identity: Remnant soul of the last guardian of the Age of the End of Dharma, the One Who Escaped, chief physician to the sick Heavenly Dao (provisional)."
"Current diagnosis: The prehistoric Heavenly Dao is suffering multiple organ failure."
"Treatment plan: Heal it, do not replace it."
And so Lu Chen takes a path no transmigrator has ever taken:
While others are busy seeking masters and fighting over magical treasures, he uses his "medical knowledge" to perform surgery on injured Ancestral Shamans.
While others take part in the Investiture of the Gods war, he mediates "medical malpractice disputes" between the Jie Sect and the Chan Sect.
While others strive to reach sainthood, he prescribes fever reducers for feverish Chaos Demon Gods.
Then one day, the gates of the Zixiao Palace open, and Dao Ancestor Hongjun personally comes down the steps to greet him:
"Doctor Lu, the Heavenly Dao coughed up blood again last night. Do you think we should adjust the dosage?"
Lu Chen calmly opens the medical chart:
"First, tell me clearly: is this an ordinary tribulation, or a malignant condition?"
"Also, settle the bill for the treatment. The merits from mending the heavens last time still haven't come through."
