Shen Tingzhou looked up at Lin Wanqiu's worried eyes, his heart filled with reluctance and guilt. He held her hand and said in a heavy tone, "Wanqiu, the mole I was on a mission back then has been found. He's on the border now, and I need to go there to assist in his capture."

Lin Wanqiu's heart tightened, and a worried look appeared on her face. She knew that the border region was fraught with danger, and the traitors were ruthless. She was really worried about Shen Tingzhou taking the risk. "Tingzhou, can't you not go? It's too dangerous."

Shen Tingzhou shook his head, his eyes resolute: "No, Wanqiu. This is not only to complete the mission we didn't finish back then, but also to give an explanation to our fallen comrades. I must go."

Looking at the worry in Lin Wanqiu's eyes, he felt a pang of tenderness in his heart: "Don't worry, I'll take good care of myself and I'll definitely come back safely. Please take care of things at the food shop and the scholarship fund."

Lin Wanqiu knew that once Shen Tingzhou made a decision, he wouldn't easily change it. Suppressing her worries, she nodded, "Okay, I support you. You must be careful and take good care of yourself. The children and I are waiting for you to come home."

She paused, then continued, "I will take good care of the food shop and the scholarship fund so you won't have any worries. You can go with peace of mind."

Shen Tingzhou hugged Lin Wanqiu tightly, his heart filled with gratitude and reluctance. He knew that his biggest worry on this trip was Lin Wanqiu and her family. But he had no choice but to shoulder his responsibility and complete this long-awaited "battle."

Before leaving, Shen Tingzhou made a special trip to Peking University to visit Shen Nian'an. Looking at his son, who had grown into a tall and handsome young man, he was filled with pride. "Nian'an, Dad is going to carry out an important mission and may not be back for a while. You must study hard at school, take good care of yourself, and call your mother often to reassure her."

Seeing her father's solemn expression, Shen Nian'an nodded despite her worry: "Dad, don't worry. I will study hard and call Mom often. Please be careful and come back soon."
