It was a mysterious feeling. According to the martial arts materials from the imperial family that Zhao Xuanxin had once shown him, one’s state of mind and martial arts were complementary realms. If one’s state of mind did not meet the requirements of martial arts, it would be impossible to achieve a breakthrough. Only by comprehending the myriad aspects of life or experiencing an unprecedented impact on one’s inner world could one elevate the realm of their mind.


    For example, in the history of the Zhao Song Empire, there was once a Level 2 innate expert who had been unable to break through for a long time. One day, his beloved wife was attacked by pirates during a trip, and her fate was unknown. In his grief and anger, he piloted a mech alone to the pirates’ lair, single-handedly killing all the pirates and successfully rescuing his wife. Shortly after returning, despite being severely injured, his martial arts cultivation unexpectedly made a breakthrough under his wife’s meticulous care, even jumping directly to Level 4.


    This was the result of a change in his state of mind—from calmness to grief and anger, to the madness of slaughter, to the excitement of rescuing his wife, and finally to the warmth after returning. The intense fluctuations in a short period allowed him to break through the shackles of his state of mind and achieve a breakthrough.


    However, all the materials indicated that changes in one’s state of mind could only be felt after reaching the innate level. At the acquired stage, even at the peak of Level 10, there would be no change in one’s state of mind before breaking through to the innate level.


    The state of mind was the most significant change from the acquired to the innate stage.


    Although Yun Yi didn’t know why he could sense changes in his state of mind, he wasn’t foolish enough to think he was about to enter the innate stage.


    But in any case, a change in his state of mind should be considered a good thing.


    The melodious music filled the small, cozy room. Gradually, Yun Yi’s mind became calm. He glanced over and saw Zhao Xiyue sitting quietly on the bed, holding her stuffed bear and listening intently. Her beautiful eyes, like black obsidian, sparkled with a slightly confused light, as if she was savoring something in the music.


    As the song ended, Yun Yi stepped forward and gently stroked Zhao Xiyue’s smooth hair, softly saying, "Xiyue, if there’s something bothering you, tell your brother."


    Zhao Xiyue looked up at Yun Yi, seemingly wanting to say something, but ultimately shook her head and whispered, "I’m fine. Brother, go attend to your own matters."


    "What could be more important than Xiyue?" Yun Yi smiled warmly, tapping her forehead with his finger.


    After hesitating for a while, Zhao Xiyue said, "Meow, Xiyue doesn’t want Brother to get to know those girls at school."


    "Huh… why?" Yun Yi was stunned, not understanding why Zhao Xiyue would say such a thing.


    Zhao Xiyue turned her face away and, after a long pause, said, "No reason. Just don’t."

    Yun Yi laughed. "How is that possible? The school isn’t just for boys. Many things require communication with everyone. Just like how Xiyue participates in choir at school, with both boys and girls, everyone shares their singing experiences. Doesn’t that help you gain more experience?"


    "Meow, although… although that’s true…" Zhao Xiyue didn’t know what to say. Her delicate hands twisted together, and her face clearly showed her hesitation. After a long time, she whispered, "Then you’re only allowed to exchange experiences with them. You’re not allowed… not allowed… not allowed to have lunch with them!"


    "Uh… alright, alright. I promise I won’t have lunch with them." Yun Yi smiled and patted Zhao Xiyue’s head.


    Perhaps in the little girl’s eyes, eating lunch together was the easiest way to build relationships.


    Seeing Zhao Xiyue’s joyful expression, Yun Yi felt a warmth in his heart. After comforting Zhao Xiyue, Yun Yi returned to his room and sighed, "I really don’t know how Her Majesty the Empress taught her daughter back then. This is too difficult!"


    The next day, Yun Yi thought of that girl again and got up early, arriving at the school gate before dawn. But even as class was about to start, the timid girl didn’t appear.


    "Maybe she’s not coming to school today either."


    With this doubt in mind, Yun Yi headed to class. After lunch, during his break, Yun Yi found the teacher in charge of off-campus accommodations and, without much effort, obtained a list of first-year students living off-campus.


    There weren’t many freshmen living off-campus. After some screening, he quickly found his target.


    Lin Moxue, female, 17 years old…


    In the series of details that followed, Yun Yi was shocked to see a line that read: Due to physical reasons, she has applied to live at home to ensure treatment effectiveness. In addition, there were four words that left him even more astonished: Martial Arts Level 8.


    So she was the Level 8 martial arts girl…


    But as a Level 8 martial artist, why was she so timid that she didn’t dare fight back against a boy who was at most Level 4? And even more puzzling was her illness. Normally, martial arts experts rarely fell ill—their strong bodies made them immune to diseases. Moreover, in today’s advanced technological age, even severed limbs could be restored using regeneration technology. What kind of illness required her to return home every day to monitor her condition and prevent it from worsening?


    This only intensified Yun Yi’s curiosity.


    But to his dismay, Lin Moxue’s file didn’t include her detailed home address, not even a photo. Perhaps she didn’t want to fill it in, or perhaps someone deliberately concealed it. Either way, it was clear that Lin Moxue came from an extremely noble family with significant influence.


    A young lady from a powerful family, a Level 8 martial artist, a girl suffering from a serious illness, a timid and shy student… These completely unrelated traits had all appeared in this one girl.


    During lunch, Yun Yi shared his findings with his friends.


    "Huh? There’s such a mysterious person in our school?" Gudrian was utterly amazed, even forgetting to eat his meal as he listened to Yun Yi’s story.


    Yang Yue’er pondered and said, "How is that possible? What kind of illness could a Level 8 martial artist have that can’t be cured?"


    Chris thought for a moment and said, "There are some rare and strange diseases that still don’t have effective treatments. But those illnesses are extremely rare—basically, one in billions might get such a disease."


    Omir also nodded. "Yes, they’re very rare. Usually, only one case appears every few decades or even centuries. But I’ve never heard of an illness that requires daily monitoring at home."


    For a moment, everyone’s curiosity was piqued by Yun Yi’s story. They sent messages to ask around and searched on their computers.


    "Could it be…" Suddenly, Yang Chengling’s words caught everyone’s attention.


    "What?" they all asked in unison.


    Yang Chengling shook his head. "I’m not entirely sure, but based on what Yun Yi said—a Level 8 martial artist who doesn’t fight back when bullied by a boy, coupled with the difficulty of curing her condition—there’s a more than 90% chance it’s… a mental illness!"


    "Mental… mental illness?"
