The day the city fell, Feng Yun was treated by her father as a spoil of war and presented to the enemy general.Everyone pitied her, soon to be a captive, plunging into a fiery pit.Yet she veiled the little donkey cart that took her out of the city tightly, daring not to let anyone see the secret delight in her heart…As a child, she behaved oddly and spoke startling words, once predicting a war in which the whole army was wiped out, nearly being burned to death by her clan as a demon.When she grew up, her beauty was out of the world, but she was rejected by her husband's family.In the period of chaos and disorder everywhewe, where could a female captive go?“I do not seek a devoted partner to grow old with; I merely wish to rule unrivaled in this life.”In her previous life, Feng Yun was always the one being scorned by others; in this life, she decided to strike first, turning the tables on each and every one of them, those so-called unreachable flowers and beasts in gentleman's clothing, those degenerates… all to be scorned in return.

That lonesome night as he lays dying in the hospital, fearing of death and desiring the taste of life, his mind became unprecedentedly complex with mixed emotions.

Myasthenia gravis — an incurable disease where one’s muscle slowly degenerated until the day when one can no longer move and only tears may flow.

“Is this… dying?”

When he opened his eyes again, he had crossed over into the body of a two months old infant, right in the middle of an assassination attempt.

He was born as the illegitimate son of a noble. His name was Fan Xian; and with that name came the burden of deep political secrets and the legacy of his mother.

He understood; to survive, he needed unparalleled strength, money and political power.

To a new world with the luxury of a new life, so named; Celebrating the Remaining Life.
