Yuecheng stands on the human race’s buffer frontier. Every night, the roars of other races echo beyond the city walls, and the martial arts college entrance exam is the only way out for poor young people.
Born with his foundation damaged by baleful energy, Jun Wuji has the worst cultivation talent of all. With a blood-energy score of 398, he ranks dead last and is subjected to endless scorn.
His father was left disabled after fighting the other races in a bloody battle, and his mother has been bedridden for years. He cannot afford to fail. If he doesn’t pass, his family will have no one to rely on.
When a classmate is killed by a demonic beast, the crushing despair opens a spatial passage deep within his heart, revealing the one-of-a-kind [Body Instance Dungeon].
A Heart Demon Realm lies in his heart, a Storm Canyon in his lungs, an endless battlefield in his muscles... Every organ is an independent secret realm connected to another world.
The adventurers who enter these realms have no idea that the secret realm’s true form is an ordinary high school senior. They explore wildly and battle the instance bosses.
One adventurer defeats the Heart Demon and gifts him an Undying Heart Furnace that keeps him calm in the direst circumstances.
Another perishes in the Bone Prison, replenishing his spiritual essence in vast quantities and helping him advance at incredible speed.
As he gradually unlocks the secret realms throughout his body, he crosses several cultivation stages in a hundred days, leaving the geniuses who once mocked him far behind.
During the college entrance exam’s live combat trial against the other races, the boy who once ranked last makes a stunning debut. When the other races launch a massive assault on Yuecheng, the countless secret realms within his body ring as one. With the power of the secret realms contained in his flesh, he protects the city’s people and finds the human race a new path to resist the baleful-energy-wielding invaders.
