Chinese Martial Arts: You Took Out a Loan to Become an Earthly Immortal?

Jiang Chen transmigrates into an age when everyone practices martial arts. Influencer grandmasters are everywhere, while traditional martial arts are treated like trash. After awakening the [Credit Martial Arts System], he can use any realm or technique before learning it, as long as he has enough "credit points"! In the ring, he faces an arrogant taekwondo champion. Jiang Chen stands with his hands behind his back. "I only need one finger to deal with you." Inside, he frantically clicks: [Advance: One Yang Finger (Perfected Realm)! Cost: Poke a steel plate ten thousand times in a row afterward!] Boom! A thunderous crash, and the champion flies out of the ring. The whole internet erupts: Is that the long-lost Six Meridians Divine Sword?! Only Jiang Chen knows that every night, he practices in the System's space until he's foaming at the mouth. "Everyone, I'm really not some peerless master. I'm just a wage slave buried under a mountain of martial arts debt!"
