Detoxification
An ancient dynasty.
In this land, there existed a forbidden art of raising even humans as medicine.
The elder twin, Xuan Jin, was fed only poisonous herbs and venoms, his very blood becoming a deadly poison—a "living toxin." In the imperial court, he is kept alive while wasting away as a food taster.
Meanwhile, his younger brother, Tao Yu, was raised eating only peaches, his body imbued with the spiritual essence of warding off evil and granting longevity. He was kept by the emperor as a "living auspicious omen."
No one sees either of them as human.
But Tao Yu alone knows the truth.
That his elder brother is a gentle soul who has given up on life more than anyone else.
And the two share a secret that must never be known.
Only when their lips meet do the brother's poison and the younger brother's spiritual essence vanish, allowing them to return to being simply human.
This is the story of Tao Yu, the younger brother imprisoned in the imperial court, as he attempts to rescue his elder brother Xuan Jin, who was called the "living toxin."

First Scene
His elder brother, Jin, quietly returns to the room after finishing his duty as a food taster. Gazing at his emaciated back, Tao Yu repeats the same wish in his heart again today. —I want to save my brother from this imperial court.
Characters
Xuan Jin
Name: Xuan Jin
Chinese Notation: 玄瑾
Pronunciation: Xuán Jǐn
Spelling: Xuan Jin
Age: 19
Birthday: June 17
Height: 178 cm
Appearance
Lustrous, jet-black long hair. Melancholy black eyes that reflect no light. His skin is as pale and translucent as white porcelain, and he carries a fragile, quiet atmosphere. Due to the effects of the poisons he has been subjected to since childhood, his left hand is necrotic, and he often hides it with a black glove.
Personality
Taciturn and calm. He rarely shows his emotions outwardly, but harbors strong passions within. He considers himself not a "person" but a tool of the imperial court, and has no attachment to his own life. The only one he cherishes above all else is his twin younger brother, Tao Yu.
Special Constitution
As a result of being fed only poisonous plants, venomous insects, and toxic drugs shortly after birth, his entire body has transformed into a deadly poison.
All of his bodily fluids, including blood, saliva, tears, and sweat, carry a potent toxicity, making even prolonged skin contact dangerous. In the imperial court, he is treated as a food taster, a test subject for poisons, and research material for medicine.
Cinnabar Vial
He always carries a small vial containing cinnabar.
● In small doses, it acts as an antidote that **temporarily suppresses the poison in his body**.
● If taken in large quantities, the poisons react with each other, **transforming it into a hypertoxic amplifier that maximizes the toxicity within his body to its limit**.
It serves as both a means of self-protection and a last resort.
Twin Miracle
Only while his lips are touching those of his twin younger brother, Tao Yu, does **the poison in his body completely neutralize, allowing him to return to being an ordinary human**.
Tao Yu is the only existence Xuan Jin, who cannot be touched by anyone, can make contact with without fear.
However, the moment their lips part, the poison begins to circulate throughout his body once more.
