On an ordinary summer evening, Lin Beixing sat quietly in front of her old mobile phone. She held the review materials for the college entrance examination in her hands, and an indescribable determination burned in her heart.She once again used this old mobile phone to return to her high school days, determined to make a splash in the upcoming college entrance examination.

In Lin Beixing's memory, the college entrance examination was a critical moment that changed her destiny, and it was also an important springboard for her to reach the pinnacle of life.However, every time she faced the exam with confidence, she always found herself back at the starting point in the evening after the college entrance examination, and everything seemed to be an endless cycle.

Being awakened from his sweet dreams again and again, Lin Beixing began to doubt his memory and perception.She gradually realized that there was an important variable in this cycle that was constantly interfering with her plans.This variable is her classmate Zhang Wansen.

Zhang Wansen, a talented young man who always ranks among the best in studies, accidentally fell into the water tower on the night after each college entrance examination, which became the key to Lin Beixing's inability to break through the time and space cycle.Lin Beixing began to reflect on whether Zhang Wansen's change in fate was the opportunity for her to break out of the cycle and realize her dreams.

So Lin Beixing decided to change his strategy.She no longer just paid attention to her review progress and exam performance, but began to pay close attention to Zhang Wansen's every move.She tried to find out the reason why Zhang Wansen fell from the tower and did everything possible to prevent this tragedy from happening.

Lin Beixing's action was not easy.She needs to cleverly change Zhang Wansen's fate without changing the historical background.She began to establish a deep friendship with Zhang Wansen and understand his inner world. At the same time, she also faced the pressure of the college entrance examination and the urgency of time.

In repeated attempts and failures, Lin Beixing gradually got closer to the truth.She discovered that the reason why Zhang Wansen fell from the tower was not a simple accident, but a series of complex factors hidden behind it.In the process, Lin Beixing also gradually grew into a more mature and tough person.

Finally, on the last night before the college entrance examination, Lin Beixing successfully prevented Zhang Wansen from falling from the tower.She used her actions to change Zhang Wansen's destiny and opened up a new future for herself.

When a new day arrived, Lin Beixing walked into the examination room with confidence.She knew that this time, she could finally break free from the shackles of the cycle and take a firm step toward her dreams and future.

After the college entrance examination, Lin Beixing and Zhang Wansen celebrated their victory together.Not only did they successfully pass this important test in life, but they also gained valuable friendship and growth.
