Rebirth in the Millennium: My Brain Is Connected to AL

On September 1, 2000, under the national flag at the opening ceremony of the third year of high school. Lu Chen woke up to the sound of the dean's lengthy speech and found that he was back in the classroom where he was eighteen years old. The sun shines through the old wooden windows, casting blurry spots of light on the mottled desks. The ponytail of the girl at the desk, the idol's name written in pen on the title page of the textbook at the same table, the bright red slogan "Work hard for a hundred days, win the college entrance examination" above the blackboard - everything was so familiar that it made his heart tighten. Just yesterday (or, yesterday, twenty-three years later), he was still a mediocre middle-aged man, sitting in the corner of the class reunion, listening to the school belle whom he once had a crush on politely and distantly asked: "Lu Chen, how are you doing now?" He couldn't answer. And now, fate gave him the chance to answer it again. Just as he was digesting the shock of rebirth, a clear and calm interface unfolded in his consciousness - a pure black background, a simple input box, and a line of shimmering fonts at the top: DeepSeek AI-Connected Lu Chen was stunned, and then an almost crazy plan took shape in his mind. In the first monthly exam, the last math question, the teacher asserted that "no one in the school can solve it." Lu Chen raised his hand: "Teacher, I have seven solutions." He walked up to the podium and while everyone was stunned, he wrote down three ingenious ideas that were completely beyond the scope of high school - future problem-solving models optimized by DeepSeek. The mathematics team held a meeting overnight, and the old professor made a long-distance call with trembling hands: "The province... No, it is the national mathematics competition training team, he must be allowed to join!"
