Great Tang: I'm a Constable, and I Train Relentlessly in the Dragon-Elephant Prajna Skill

Wen Changan transmigrated to the eighth year of the Zhenguan era in the Tang dynasty, where he became a low-ranking constable. A good-for-nothing at martial arts, he dreamed of doing nothing and living off others. At this moment, he was squatting in an outhouse, facing a translucent virtual screen floating in the air. It read: [Ding! Your transmigrator's starter pack has arrived!] [Congratulations, Host. You have unlocked “Ultimate Wellness Exercises”...] Wen Changan's face remained blank. He knew it. The heavens never dropped free pies. They only dropped iron ones. [...Reach the pinnacle of mastery to unlock the next level of techniques!] Fine. Wellness exercises it was. At least they could keep him fit. Resigned, he nodded. In the next instant, four dazzling golden characters nearly blinded him: [Dragon Elephant Prajna Skill]! Wen Changan sucked in a sharp breath. Even the stench of the outhouse seemed to turn sweet. The Dragon Elephant Prajna Skill! The most absurdly overpowered technique in Jin Yong's martial arts novels. Once mastered to the thirteenth level, it gave the user the power of ten dragons and ten elephants. One punch, and even a city wall would call him Dad. “System Dad! I was wrong about you!” He nearly wept with joy.
