After the success of Arya's "Dance of Healing" at international scientific conferences, she received invitations to collaborate with many research institutes and hospitals. Among them, a well-known neurorehabilitation center in the federal capital was particularly intriguing. The center hopes to work with her to study the potential of dance in helping stroke patients regain motor function. Arya, Erin, and Leeson decide to take on the challenge. They formed a multidisciplinary team, including neuroscientists, physiotherapists, and dance therapists, to develop an art therapy that incorporates dance for neurological rehabilitation. In the early stages of the project, the team faced many difficulties. Scientists are skeptical that dance can have a substantial impact, and patients need time to get used to this novel treatment. However, Arya didn't give up. She believes that through her dance, she can help these patients regain hope in life and balance in their bodies. One day, during a treatment, a stroke patient named Mark was gradually able to lift his arm that had been paralyzed by the stroke under the guidance of Arya. When Mark's fingers were able to flex slightly for the first time, everyone was stunned. This small step forward not only proves the effectiveness of dance therapy, but also injects new impetus into the whole project. Inspired by this, Arya began to create more dances for different neurological disorders. Her "Dance of Balance" helps people with Parkinson's disease improve their gait, and "Dance of Breathing" offers a new approach to breathing training for people with asthma. With the passage of time, the application of dance therapy in the medical field has become more and more widespread. Many hospitals have started to set up dance therapy departments, employing professional dance therapists to provide services to patients. Arya's name spread throughout the Commonwealth, and she was hailed as a "pioneer in dance therapy." However, just as the project made a major breakthrough, Arya began to feel physically and mentally exhausted. The long hours of intense work and the tremendous pressure caused her to gradually lose her passion for dance. She began to question whether she had taken the wrong path and whether she should continue on this seemingly endless path of scientific research. Erin and Li Sen saw it in their eyes and were anxious in their hearts. They knew that Arya needed more than just a break, but also a rediscovery of her passion for dance. So, they decided to take Arya back to the distant planet that once faced an environmental crisis, and let her find inspiration and strength there. When Arya set foot on that planet again, she was stunned by what she saw. The once barren land is now covered in greenery, the dry rivers are flowing again, and the skies are clear and bright. Local residents welcome the federal visitors with their traditional dances, and their laughter and dancing are filled with love and hope for a new life. Arya stood in the garden, feeling the breeze on her face and the sun shining on her. She closes her eyes and recalls when she first started dancing. At that time, she simply enjoyed the joy of dancing without any utilitarian purpose. And now, dancing seems to be a responsibility and a burden.Suddenly, she heard footsteps behind her. When she turned her head, it was Erin and Leeson smiling at her. "Kids," says Erin, "sometimes we get so caught up in the goal that we forget why we started. Dance is not just a tool for healing, it is expression, it is freedom, it is love. With this in mind, you'll be able to find your way forward. Arya nodded, tears rolling in her eyes. She took a deep breath and began to dance in the garden. Her movements are light and free, as if in dialogue with the breeze and the sun. As the dance progressed, she felt the pressure in her heart gradually dissipate and her love for dance was rekindled. When she finished the dance, Erin and Leeson applauded her warmly. Arya felt relieved that she had finally found a balance – that dance could be both an art and a science; It can be both therapeutic and pure enjoyment. Back in the Federation, Arya gets back to work, but this time, she's less obsessed with results. She began to add more personal emotion and creativity to her dances, making the healing process more vivid and effective. Her patients report that the dance makes them feel more understood and healed. Years later, when Arya stood on stage for her first "Dance of Healing," she was filled with gratitude as she watched the countless patients in the audience who had changed their lives because of dance. She knows that as a dancer or as a scientist, she is writing her own legend. And it all starts with a girl who believes that dance can change the world.
