These Years I Was a Captain at the Six Doors

After transmigrating to become a constable of the Six Doors, Ling Yun is a little dazed. How is he supposed to catch those peerless demons with world-shaking martial arts?

Xiong Ba, Yan Kuangtu, Blood Saber Patriarch, Heavenly Thunder Demon...

Are these really enemies a minor constable like him can arrest?

"Congratulations, your crime reasoning was correct. Reward: legendary martial art Vajra Indestructible Divine Art!"

"Congratulations, you have been promoted to bronze constable. Reward: peerless martial art Wind God Leg!"

"Congratulations, you have been promoted to silver constable. Reward: peerless movement technique Snow Treading Without a Trace!"

"Congratulations, your reputation has reached world fame. Reward: peerless martial art Cosmos Reversal!"

"Congratulations, you have been promoted to golden constable. Reward: legendary martial art Tathagata Palm!"

...

Hmm, that makes things easy!
