Princess Le Yao, the troublemaker of the imperial palace, discovers that her father has gone gray with worry over the notorious corrupt official Yan Song. Forbidden from investigating the case? No big deal! She drags along Qing Dai, her ruthless, tight-lipped maid skilled in medicine and martial arts, climbs over the palace wall, and heads into the jianghu!
The waters in the capital are murky, which makes it the perfect place to fish around: Xiao Che, a wealthy swordsman who rejected an arranged marriage and left home, and Lu Xiaochuan, an inventor obsessed with gadgets who carries a box of "junk." A bizarre murder brings all four of them together:
Le Yao's sharp intuition exposes the lies, Qing Dai's silver needles reveal a deadly poison, Xiao Che's sword drives back the hidden assailants, and Lu Xiaochuan's supposedly "useless" inventions turn out to be perfect tools for solving the case! Amid their banter and bickering, the clues point straight to the tip of the iceberg of Yan Song's embezzlement!
Go back to the palace? Not a chance! History's most unconventional anti-corruption squad makes its debut on the spot: a princess, a runaway young master, a cool-headed physician, and a talkative inventor. With the dangers of the jianghu ahead and a web of corruption behind them, each also harbors secrets left unspoken...
Watch them solve puzzles with their quirky cleverness and triumph through ingenious contraptions, carving a ray of clear light through these troubled times amid flashing blades and laughter!
The jianghu road is long. Corrupt officials, prepare yourselves!
