The police and Qian Niandi waited in the house for more than half an hour, and finally heard the door open.

Zheng Chun and Zheng Xia were still unaware of what was happening in the room. As they entered, they said to Qian Longfei, "You cooperate well with Ji Zong's matching test. Once Ji Zong's surgery is complete, we'll let you go..."

Qian Longfei asked: "What about my sister?"

Zheng Chunhui: "She is not your biological sister, but a member of our Zheng family. She must stay in the Zheng family. We are her family and will definitely not harm her. But if you don't save Ji Zong, then who knows..."

Qian Longfei probed: "If my brother doesn't survive, what are you going to do?"

Zheng Chun said, "We can't say for sure. We have to listen to my mother's arrangements. Okay, stop talking nonsense. Just cooperate with Ji Zong's treatment. You don't have to worry about anything else!"

The three of them walked in while talking, and only then saw someone in uniform in the house.

Zheng Chun and Zheng Xia looked at each other and felt that something was wrong.

Before they could react, Qian Niandi walked out from behind the police and shouted to Qian Longfei, "Xiaofei, I'm fine. Come here quickly. Don't listen to them. Zheng Jizong's life or death has nothing to do with you. This is not your responsibility!"

When Qian Longfei saw the police, Qian Niandi was in good spirits and her tense nerves immediately relaxed. She wanted to get rid of Zheng Chun and Zheng Xia and walk to the other side.

Who knew that at this moment Zheng Chun put a spring knife on Qian Longfei's neck and threatened: "If you dare to leave, I will kill you now..."

She confidently explained to the police, "He and my brother are brothers, and only he can save his life. If you want to take me away, you have to wait until my brother has surgery. We have no choice but to do this. Human life is at stake, and you, as police officers, can't be so heartless, right?"

The two women were able to control Qian Longfei not only because of Qian Niandi as a hostage. They also made preparations for both situations, holding a switchblade against Qian Longfei to force him to cooperate, otherwise going to the hospital would not have been so smooth.

Zheng Chun's actions shocked the police officers present, and her words were completely illogical. She even described such blatant illegal behavior as justifiable.

The police officer was worried that Zheng Chun might accidentally hurt Qian Longfei due to his emotional outburst, so he patiently tried to appease him: "Put the knife down first, and let's talk things over. If you use a knife, the situation will change..."

Zheng Chun did not put down the knife, but replied to the police: "I am also trying to save lives. You can ask me to put down the knife, but leave Qian Niandi here, and you two can leave now..."

The police were speechless. Zheng Chun didn't look that old, so how could he not understand the law?

He then went on to explain to Zheng Chun, "You illegally detained people and took hostages. Do you know how many years you'll be sentenced to? I understand your desire to save your family, but you have no right to force others to do so. Do you understand?"

Zheng Chun defended himself, saying, "My brother has no blood relationship with our family. We all wanted to spend all our money to save him, but this blood relative refused to donate bone marrow even when we begged him on our knees. He forced us to do this."

Qian Niandi looked at the spring knife with its blade already extended, pressing against the carotid artery in Qian Longfei's neck, and was afraid that Zheng Chun would accidentally hurt Qian Longfei.

She stepped forward to negotiate: "Let my brother go, I will be your hostage..."

Zheng Chun said, "Don't even think about leaving. If you hadn't stopped your brother from getting a matching test, would we have resorted to this desperate measure?"
