The Pill Sect's discarded medicine cost his sister her life. He was beaten and had his leg broken while begging for medicine, then left for dead in a mass grave.
At death's door, Lin Yue, a lowly rogue cultivator, awakened two black tortoises that had slept for ten thousand years with his blood.
The Black Tortoise commands heavenly lightning to punish evildoers, while the Green Tortoise excels at detection and stealth. Though endowed with the power of the Heavenly Dao, they are bound by strict rules:
Without solid evidence, he cannot summon lightning. Abuse its power and his meridians will be shattered. He cannot stand against those above Foundation Establishment, and if his lightning aura is exposed, he will be hunted down.
He strikes down villains with ironclad proof and escapes deadly traps with cunning.
A fake-pills case leads to the sect's dark secrets, while the pursuit conceals mysteries from ten thousand years ago.
The Pill Sect's powerful elite, the Sword Sect's false venerable, the evil rites of the ice fields... Anyone who stands in his way will be blasted to death by heavenly lightning.
From a lowly rogue cultivator crawling out of a mass grave to a wielder of thunder famed throughout the immortal realm,
Lin Yue climbs ever higher, stepping through the mire, vowing to uncover the truth behind the Heavenly Dao's collapse and protect his sister so she can live in peace.
