The dormitory was spotless. Whether it was the low, medium, or high-tier rooms, Zhu Yanyi was satisfied with the living conditions. After checking the surroundings, the two of them walked to the door of Class Low-A (2). Although it was the weekend, students in the special youth class could either enjoy every day off or be so busy they lost track of time, wishing a single day could stretch into several. Therefore, many students were still in class during the day.
As Zhu Yanyi reached the classroom door, she immediately saw Zhu Zhibin passionately discussing a problem with someone.
"I think this formula isn't proven this way." Zhu Zhibin took out a pen and wrote rapidly. His handwriting was swift like a swimming dragon, yet clear and legible. "I've studied the advanced fractional structure. The formula you mentioned splits one square root into two. I feel this method is unreasonable. If it were me, I would assume the square root directly as two separate roots…"
It had to be said that Zhu Zhibin was incredibly sensitive to numbers. He seriously wrote out his own proof method to support his viewpoint. Others joined the discussion, with some agreeing and others disagreeing. In the end, Zhu Zhibin won the argument.
Zhu Yanyi watched this scene from the window, a smile appearing in her eyes. This was a side of her brother she had never seen before. At this moment, Zhu Zhibin seemed to radiate a brilliance usually unseen. That confidence and joy came from the charm of numbers. It seemed Yan Aohan was right; being here would help Zhu Zhibin achieve her potential.
Feeling someone watching her, Zhu Zhibin looked up. A huge smile spread across her face. "Second Sister!" She ran out, ignoring the curious glances of her classmates toward Zhu Yanyi.
Zhu Yanyi laughed. "Why are you running? I'm not going to fly away."
"Second Sister, why are you here?" Zhu Zhibin asked curiously. She then noticed Yan Aohan behind Zhu Yanyi and greeted her shyly. "Hello, Brother Yan."
Yan Aohan’s expression was gentle. He nodded slightly to acknowledge the greeting.
Zhu Yanyi replied, "I came to see you." She continued, "We haven't been in touch much since you left the courtyard. I was in military training recently, so it wasn't convenient to visit. Now that training is over and I have a few days off, I specially came to see you." She then asked with care, "Are you getting used to it here?"
"I'm quite used to it," Zhu Zhibin said directly. "Second Sister, you don't know. Here, I finally found people my age who understand me. I am very happy here." Zhu Zhibin looked at Yan Aohan with gratitude. If not for him, he wouldn't have been able to come here.
Zhu Yanyi could hear the sincerity in Zhu Zhibin's words. She nodded with a smile. "That's good. I brought some snacks for you. There are Lv Da Gun (rolling donkeys) bought here, and some items from our home. I divided them into three portions: one for Eldest Sister, one for you. Take them back to your dorm, tidy up, and you can share them with your roommates or classmates, or give some to your master."
"Okay." Zhu Zhibin nodded, not minding at all. "By the way, Sister, there is an international math competition in October. My master suggested I try it."
"Then go try it," Zhu Yanyi said, not stopping her. "Just remember one thing: don't be proud if you win, and don't be discouraged if you lose. You are only nine years old. Life is long, and gains and losses are normal parts of it."
