A Beijing socialite stole my boyfriend; she went crazy after I got married.

Jiang Chu stopped what she was doing.

There was a person standing next to the bench there.

Jiang Chu noticed her when she entered the venue. At that time, she was doing a set of hanging one-arm pull-ups with her back to him.

And it's very easy to do.

...Because you could tell it was a woman just by looking at her back, Jiang Chu was very impressed at the time.

Upon closer inspection, Jiang Chu's heart skipped a beat.

The other person was very tall, probably around 1.8 meters, and was wearing flat shoes.

She looked slightly thin, wearing a dark gray workwear vest and work shorts, with clearly defined arm muscles and abs.

—This is the physique that can only be honed through high-intensity, extreme training.

Moreover, it is extremely functional.

It's definitely not just for show.

Jiang Chu was well aware of this, which is why she was shocked.

The other person looked to be about fifty years old.

The person had jet-black hair streaked with silver, a mixed-race face with deep-set eyebrows and high cheekbones, and deep gray-green eyes that were cold and sharp.

If it weren't for the unmistakable wrinkles around her eyes and forehead, judging by her figure and posture alone, she could easily pass for someone in her thirties or forties.

"pretty."

The woman spoke.

Her voice was low, with a unique magnetism, and she spoke Chinese extremely fluently, as if it were her mother tongue.

Jiang Chu guessed that one of the other party's parents must be Chinese.

Are you a gymnast? Or a dancer?

"Dancing," Jiang Chu smiled, "classical dance."

The woman raised an eyebrow. "No wonder..."

As she spoke, she strode over with a brisk and confident air.

"My name is Sigrid."

The woman stretched out her hand, which was covered with thick calluses.

"I came to China to attend an industry forum on exercise physiology and extreme physical fitness, and I'm staying here for a few days."

"Hello, my name is Jiang Chu."

The two held hands, and Jiang Chu could clearly feel the solid strength unique to extreme athletes emanating from the other's palm.

"I've always been interested in the visual effect of 'dissolving gravity' in your dances."

Sigrid loosened her grip, crossed her arms over her chest, and casually leaned against the holographic railing beside her, her gray-green eyes fixed on Jiang Chu.

"In extreme physical training, we pursue how to use the most perfect mechanical structure to fight against gravity and conquer height. But those few seconds you were in the air just now gave me the feeling that you were using gravity to complete your own physical narrative."

These words unexpectedly struck at the very issue that Jiang Chu had been grappling with for the past two weeks.

The original syntax of actions.

Stripped of cultural symbols, what is the most fundamental grammar of human movement?

Jiang Chu's heart rate quickened slightly. "Actually... there are many advanced aerial movements in classical dance that are not achieved by brute force."

She moved a few steps to the thick, soft padding area next to her, and smiled at Sigrid. "It's achieved through breath control and a kind of 'upward-downward' muscle pre-coding. You can watch this movement."

After speaking, he lightly tapped his feet on the soft mat.

She lifted her leg, twisted her waist, and rose higher.

In a cloud that is extremely well-defined and rises at an astonishing height!

Like a wisp of smoke that explodes and then gathers back in the wind.

The moment she landed, her right foot brushed against the mat, and using the remaining spin, she did a side somersault and flew out, skimming the ground.

As she landed, her calves and toes traced a large semicircle in the air, smoothly transitioning into a graceful leg twist.

The three movements were completed in one smooth motion.

Jiang Chu landed steadily.

Sigrid's eyes lit up to the extreme in that instant.

"marvelous."

The woman clapped her hands. "At the moment of takeoff, your rectus abdominis and obliques contracted to their limit in a fraction of a second, but your trapezius and deltoids were completely relaxed. This extreme separation of local muscles is rarely seen in many athletes. And that side somersault you just did—"

Sigrid suddenly straightened up and strode to the edge of the cushion.

Is this the correct logic?

Before Jiang Chu could react, this woman, who looked to be about fifty years old, pushed off the ground with both feet with remarkable firmness!

Then he completed a terrifyingly powerful side somersault in mid-air!

"Bang."

When the woman landed, her legs were firmly planted on the mat.

Jiang Chu: "Yes...but you're really amazing too..."

"This is just a basic functional hang time technique."

Sigrid clenched her forearm muscles. "In Reykjavik, when you're cross-country skiing in the winter, if you encounter a sudden crevasse, you need even more explosive power to take off in an instant."

The two then began a lively discussion.

Jiang Chu soon discovered that Sigrid's expertise in exercise physiology and human anatomy and mechanics was frighteningly high.

Sigrid could explain every question she posed to her clearly using the most straightforward and fundamental neural mechanisms.

They even used their fingers to draw specific muscle groups on their abdominal and back muscles as a demonstration.

"Sister, you're amazing!" Jiang Chu became increasingly excited, her words growing ever sweeter. "Are you a university professor?!"

"I have given some lectures," Sigrid said, seemingly wanting to laugh at the title, "but teaching at school is just too much trouble..."

She paused slightly as she spoke, looking behind Jiang Chu.

Jiang Chu also turned her head away.

Xie Jing is back.

He looked at the two of them and strode confidently toward them.

Jiang Chu was torn between whether she should introduce him and whether he would inexplicably become jealous again.

Xie Jing stopped in his tracks.

His expression was somewhat subtle, with a hint of relief and joy in his eyes, but also a touch of helplessness, as if he had known this would happen all along.

...Why didn't you know sooner?

Jiang Chu wasn't sure if her feeling was right.

Xie Jing first looked at her, giving her a supportive look, and then looked at the woman, uttering a string of words that were quite unfamiliar to him.

"Sæl, mamma. Langt síðan."

The syllables sounded somewhat stiff, with many peculiar trills and voiced sounds. The speech was not fast, but the tone was deep and extremely familiar.

Sigrid smiled and patted him on the shoulder.

"Já, strákurinn minn."

They then said a few more words.

Jiang Chu opened her eyes wide.

Even though she couldn't understand the language, or even know which language it was, she heard some universal pronunciations.

She wasn't sure if it was what she thought.

Xie Jing continued talking to Sigrid. They both looked calm and composed, like two old friends who hadn't seen each other for years greeting each other and catching up.

but--

Jiang Chu could tell that her boyfriend was still very relaxed.

After exchanging a few words in a foreign language, Sigrid turned her head and gave Jiang Chu a somewhat teasing look. "You have better taste than I do."

Xie Jing nodded, "I think so too."

Jiang Chu blinked. "Was that sentence directed at me, or at you?"

"...I guessed so," Xie Jing put his arm around her shoulder and pulled her closer to him. "Chu Chu, let me introduce you."

As he spoke, he looked at the woman opposite him who was watching them with her arms crossed and an expression of great interest.

"This is Ms. Sigrid Lee Gunnarsdottir."

Xie Jing said, word by word, "It's the founder of this club. And my mother."
