"Alright, let's not talk about this for now. I'll explain it to you slowly in the future. Let's deal with the bruising on your arm first. If the bruising doesn't disperse, it could lead to permanent damage over time. You've been practicing well these days, you have talent. Your sister didn't choose the wrong person. Since you're here, I'll teach you all the martial arts I know. As for that Captain Collins, if you want to get back at him for what he did to you, just break one of his arms."

Catherine Turner unhurriedly unwound the golden thread wrapped around her index finger, then straightened it out.

Only then did Charles Warren realize that it was actually a golden acupuncture needle over a foot long.

Chapter 10: The Profound Skills in Taiji Push Hands

After straightening the foot-long golden needle, Catherine Turner gave her hand a flick, and the needle, like a loach burrowing into a hole, suddenly pierced into Charles Warren's elbow joint. As Catherine Turner's right thumb and middle finger twisted the end of the needle, the needle, over a foot long, actually went seven or eight-tenths of the way into the flesh.

Charles Warren watched, his heart pounding, but even though the needle went in so deep, he didn't feel any pain at all. Instead, there was a faint, cool, comfortable sensation moving through his arm.

The needle stayed in for half an hour before Catherine Turner gave another flick of her hand, swiftly pulling the needle out and wrapping it around her finger again as a ring. At this point, Charles Warren's arm seemed to have regained some of its original feeling, but the purplish-black bruising and swelling still hadn't disappeared.

After putting away the golden needle, Catherine Turner didn't pause. She suddenly grabbed and lifted Charles Warren's entire injured arm, and with her other hand, began kneading and massaging the bruised, swollen area at the elbow.

This time, Charles Warren felt as if there was a faint electric current in the center of Catherine Turner's palm. Each kneading motion sent a jolt through the nerves in his skin and muscles.

Gradually, damp sweat began to flow from the area being massaged. Charles Warren knew this was sweat drawn out by the hidden force in the palm.

The hidden force released by Catherine Turner surged out from the pores in her palm, penetrating into the bruising in Charles Warren's arm.

Little by little, the purplish-black swelling and bruising began to fade. In the end, Charles Warren's entire arm and fist felt as if they'd been pulled out of water, drenched with sweat brought out by Catherine Turner's hidden force.

"Mm-hmm, mm-hmm, mm-hmm, mm-hmm..." At this moment, Charles Warren's ears caught a deep yet subtle sound, like the lingering rumble of thunder slowly rolling across the sky.

"Where is that sound coming from?" Charles Warren paid attention and realized that all the joints in Catherine Turner's body were trembling slightly. The sound of the joints vibrating merged into a faint, continuous hum, finally gathering into that deep, thunderous resonance.

"Alright! Just rest for another half a day and you'll be fine. No need to apply any medicine—let it heal naturally. All medicine has some toxicity, which must be expelled through the kidneys. Overusing medicine will harm the kidneys, whether taken internally or applied externally, it's the same."

After finishing the massage, Catherine Turner let out a long breath. At this point, all the swelling on Charles Warren's arm and fist had disappeared, leaving only some faint reddish marks.

"Chen-jie, your palm is sweating so much..." Charles Warren murmured.

"Hidden force consumes a lot of physical energy. If your martial arts haven't reached the level of 'Yi Sui' (Marrow Transformation), you can't use too much hidden force, or your heart will fail quickly and your body will collapse within a few years."

"What is 'Yi Sui'?" Charles Warren asked. Although two months ago in the park, Catherine Turner had explained to Charles Warren about 'Ming Jin' (Obvious Force), 'An Jin' (Hidden Force), 'Hua Jin' (Transforming Force), and the concept of 'Qi', he had never heard of this 'Yi Sui'.

Catherine Turner nodded after hearing this, but didn't answer immediately. She simply pressed a button on the armrest of the sofa. In a short while, a servant appeared at the door. She asked the servant to bring a large basin of warm water and a towel. Catherine Turner washed her hands, then told Charles Warren to wash his arm as well.

"You can go now, no need to take the water away," Catherine Turner instructed. After the servant left, she said to Charles Warren, "Come, take the water out and pour it on the lawn in the garden."

Charles Warren immediately picked up the basin of water and followed Catherine Turner out of the villa to the lawn in the front garden.

"From today on, I will officially teach you martial arts," Catherine Turner said as she saw Charles Warren standing ready. Her expression turned cold, and Charles Warren felt that his usually gentle sister had suddenly become a different person, exuding a sharp and chilling aura. He had only ever felt this way once before, when he saw a leopard or tiger hunting at the zoo, but even then, it wasn't as intense as what he felt from Catherine Turner now.

"Up to now, I suppose you're very curious about your sister's background, aren't you?" Catherine Turner said.

"Yeah," Charles Warren nodded. He wanted to ask, but had a strong premonition that if he did, he might lose something most precious. Some things, it's better to remain in the dark about forever.

"Good thing you never asked before. If you had, maybe I wouldn't have taught you," Catherine Turner said, as expected. "The world I come from is beyond your imagination, and not something you can come into contact with. I came to the mainland this time on a whim. When I met you and taught you some things, it was just to see if you had the aptitude. But since you've made progress, it means you do have talent. That's why I'm leaving my skills here on the mainland, to find an inheritor. Otherwise, if the lineage were to end one day, that would truly be a pity."
