Solving Cases Makes Me Stronger: The Good-for-Nothing Prince Consort Goes on a Rampage

After marrying into the Princess Royal's household, Li Changgeng was mocked across the city as a useless, good-for-nothing consort, powerless and constantly belittled and oppressed.

But there is always a way forward. He awakened a System that rewarded him with cultivation, martial arts, and divine weapons for solving cases.

Investigating a massacre, he smashed through walls to capture the culprit, tore apart the prince's manor's schemes, and face-slapped the powerful members of Prince Ning's household...

In return, he received a wealth of rewards. The Yijin Jing cleansed and transformed his meridians, while the Nine Suns Manual, the flying knife technique, and the Formless Void-Shattering Sword all reached complete mastery.

In a single transformation, he broke through one realm after another from the peak of the Xiantian realm, advancing several realms in a row and charging straight into the fourth layer of the Grandmaster realm.

With the Princess Royal's personal sword in hand, his combat prowess crushed anyone at the same level, and he could even slay powerful foes above his own level.

From then on, every difficult unsolved case at the Judicial Guard was cracked as soon as he took it on, and he swept aside every powerful figure in the imperial capital who dared to provoke him!

The Han clan's plots, the prince's manor's schemes, and a sinister flower-plucking fiend appeared one after another, with layers upon layers of conspiracies...

With the brilliance of a master detective, Li Changgeng unraveled every mystery, and with peerless martial arts, he subdued all opposition.

Who says every live-in son-in-law is mediocre?

Starting as a good-for-nothing consort, he turned his life around step by step, solving the world's most extraordinary cases and ascending to the peak of the martial path.
