Episode 24 recap: Yang Wei Ning helped Ye Wen Jie.

During their time at Hong'an, Lei Zhi Cheng and Yang Wei Ning encouraged the young Ye Wen Jie to continue her research work. Ye Wen Jie was aware of the challenges in research, and she was prepared to admit that she hadn't made any significant progress. However, she unintentionally overheard Yang Wei Ning and Lei Zhi Cheng discussing their intention to provide an environment for her to continue her research.

Afterward, Ye Wen Jie didn't submit her report. She knew that if she did, she wouldn't have access to advanced engineering data. However, her decision soon led to a new discovery. So, Ye Wen Jie continued her repetitive work day after day. One day, she made a tremendous breakthrough and excitedly approached Yang Wei Ning to share her new finding. She speculated that the sun was an amplifier for radio waves, and humans could utilize it to send unprecedented signals into space. When Yang Wei Ning heard her explanation, he was also filled with excitement. However, the practical challenge was to establish contact with foreign scientists to confirm this possibility, which was extremely difficult. Nevertheless, Yang Wei Ning was determined and prepared to help Ye Wen Jie apply for this opportunity. Ye Wen Jie also decided to give it a try by directly sending signals through the Hong'an launch system.

However, Lei Zhi Cheng strongly opposed Ye Wen Jie's extraordinary idea. Yang Wei Ning, who was standing nearby, actually supported Ye Wen Jie's idea and hoped she would take a risk. But there were significant risks involved, which left Ye Wen Jie even more disappointed. Although there were people around her urging her to give up, she didn't follow Yang Wei Ning's suggestion and continued to seek an opportunity to complete the experiment. Later, the Hong'an launch machine encountered a problem, and Ye Wen Jie successfully found a rare opportunity to complete her work, using the excuse of work to do what she wanted.

Just as she was about to press the launch button, the machine emitted a loud alarm. Frightened, Ye Wen Jie hurriedly left the scene to seek help from others. Upon learning that Ye Wen Jie had sent a signal using the Hong'an system without authorization, Yang Wei Ning warned her not to tell anyone. Subsequently, Yang Wei Ning obstructed Ye Wen Jie's experimental conjecture in various ways. When she was feeling disappointed, Yang Wei Ning quickly presented a reply from foreign experts. This reignited the fighting spirit within Ye Wen Jie's heart. However, she was soon hit with disappointment, which deeply affected her strong spirit. Unbeknownst to her, from that moment on, the sounds emitted by Earth had been gradually traveling through space at the speed of light.

As Ye Wen Jie recalled this exciting past experience on the stage, the audience below was also thrilled and echoed her with great enthusiasm. They even chanted slogans. After the launch, Ye Wen Jie's life returned to its previous calm state, and she successfully married Yang Wei Ning. Due to their past mistakes, Ye Wen Jie and Yang Wei Ning both lost their positions—Ye Wen Jie as an engineer and Yang Wei Ning as the chief engineer. They continued to work at the Hong'an Base as ordinary technical personnel. Soon, life became very peaceful, and this made Ye Wen Jie begin to realize another negative aspect of humanity.

The madness of humanity did not stop its relentless pace. The surrounding environment was being destroyed, and the madness reached uncontrollable levels. As an idealist, Ye Wen Jie knew that her actions were ultimately meaningless, and she continued to live a repetitive and purposeless life. This kind of existence continued for a long time.

It wasn't until November 21, 1979, that everything changed dramatically. On that day, Ye Wen Jie unintentionally heard a highly unusual frequency. After urgently translating it, she realized that it was the message "Do not answer."
