SUMMARY:
Wu Yu, a seemingly mild-mannered and cowardly new detective in the Jinhai Public Security Bureau, was actually a legendary undercover agent who had a great deal of achievements under his belt, and his return from hell after the twelve-year undercover had triggered a serious psychological disorder which made him unable to integrate into modern society,. Bu Chonghua, Captain of the criminal investigation unit, was an elite, hard-nosed, strict, perfectionist workaholic. He changed his attitude toward Wu from being prejudicial to understanding, and the two worked together to solve a series of bizarre cases as the Internet criminal group emerged from the data trench.
The guts of a teenager slaying a dragon with a single sword in the abyss is backed by a plan that spans two generations. Evil thoughts, greed, loyalty, faith, coalesce into one battle after another, in this road shed countless people's blood and sweat hard to move forward, ignited thousands of lights, swallowed thousands of mountains and seas.
