Lin Haisheng replied, "The police informed us. Also, your classmates couldn't get in touch with you, so they gave us a call."
Then, he changed the topic and began to ask the question that he was most concerned about.
"Son, why on earth did you fight with someone?"
Lin Bai answered casually, "Because if we don't stop that person, he will kill many people."
Lin Haisheng was stunned. "What happened?"
Lin Bai briefly described the situation at that time.
After Lin Haisheng heard it, he said indignantly, "Then you were acting heroically! It's fine if they don't praise you, but why are they detaining you!"
Mrs. Lin was equally indignant.
"There's no reason to be detained for acting heroically! No, we have to get an explanation for this!"
Lin Bai said, "Dad, Mom, there's no need..."
Mrs. Lin interrupted him angrily before he could speak, "Why is there no need? If bravery is said to be a fight, how can there be justice!"
