Chapter 340: "Tang Si, it's the green light."

Tang Si's question was very plain, but it was like a depth bomb, causing waves in their hearts.
The look on his face changed instantly.
Liu Zhong's wife and daughter are obviously problematic, but why choose to hide their family is not harmonious.
At this time, Song Yi gently pulled Tang Si's hand.
Tang Si lowered his head and looked towards Song Yi. The two people made eye contact, and Tang Si nodded.
Song Yi then slowly stood up.
"What's your name?" She stared at the eldest daughter, with a smile in her eyes.
The eldest daughter didn't speak, and Song Yi didn't care about her attitude either.
"Let me analyze it." Song Yi looked at them straightforwardly, his vision was too thorough, as if he could see through their souls.
The eldest daughter felt a little pressure in her heart.
"Your family relationship is not good, but you don't divorce or separate because you can't bear such a good resource. Once you divorce, divide your property, and save face, you won't be as glamorous as before."
"It's actually nothing, rich family. This kind of relationship is not unusual at all, but why do you choose to hide it?" Song Yi looked at the eldest daughter: "Your father has passed away, but I didn't feel your sadness, even You are pretending, and even, deep in your heart, you are happy."
Liu Zhong's wife was a little anxious, and pointed to Song Yi's nose: "Why do you say that to my daughter?"
Song Yi stood there, facing her face to face, smiling calmly: "Is your husband's relationship with your eldest daughter good or not?"
"If I guessed correctly, Liu Zhong’s original spouse should have died or divorced and you were remarried by him, but your eldest daughter was born to your ex-husband and not Liu Zhong’s biological daughter. The younger daughter is you and Liu Zhongsheng. Yes, but you are still preparing to have your next child, because Liu Zhong is not satisfied that you gave birth to a daughter."
"No!" Liu Zhong's wife shouted.
Song Yi chuckled his lips and chuckled, "No, the thermos you brought in is all medicinal materials for pregnancy. Don't say this is for your unmarried eldest daughter."
After saying this, the woman who was originally full of arrogance instantly lost her confidence.
"Does this have anything to do with the case?" the eldest daughter asked.
"At least it proves that you are not cooperating with the police to lie." Song Yi looked at Tang Si: "I guess Liu Zhong's autopsy report did not actually du, nor did it have a history of sucking du, but their descriptions looked like sucking du. "
"I think you should know what Liu Zhong injected."
Song Yi's words and sentences are well-founded. This speculation is not so professional, but it is very detailed and deep.
Tang Si put his hands around his chest, and touched his elbow slightly: "What are your suggestions?"
"I think your intuition is not wrong." Song Yi leaned close to Tang Si and said, "He should have injected Du Lengding."
Hearing this, Tang Si's eyes changed slightly. He was a little surprised and unexpected. He didn't know Song Yi would understand this.
Du Lengding is generally used for pain relief, but the dosage is strictly controlled, otherwise it will become addictive.
The side effects are great.
Why did Liu Zhong rely on Du Lengding for pain relief? What pain does he have? How could his doctor prescribe this drug to him?
He also kept injecting repeatedly into the same place on the arm, which caused that point to be ignored during forensic examinations.
This doctor is very suspicious.
Tang Si nodded, tilted his head to say something in Song Yi's ear, and then Song Yi walked out.
After she went out, Tang Si quietly looked at Liu Zhong's wife: "If you refuse to cooperate with the police investigation and questioning, you can still be sentenced."
This sentence acted as a deterrent to Liu Zhong's wife.
There is an obvious change in look.
On the other hand, the eldest daughter was calm and calm from beginning to end, except for the absence of a smile on her face, everything was calm and calm.
The psychological quality is too strong to be like an ordinary person.
Tang Si has been observing her micro-expression, this girl who does not seem to be very old, calm and abnormal.
Tang Si retracted his gaze and fell on Liu Zhong's wife: "Why did the youngest daughter go to the hospital?"
Liu Zhong’s wife replied: "The dripping Guanyin in the restaurant is ignorant for children. The dripping Guanyin is poisonous. She went to play, got the water on her hands, and wiped her eyes with her hands, causing... Blind."
Liu Zhong's wife said with tears in her eyes, she couldn't help crying again: "She is still so young..."
Tang Si did not show sympathy on his face, his face was clear and indifferent, and he lowered his head and took out his mobile phone to send a message to Zhou Liang: "Inquire about who raised the dripping Guanyin in the restaurant."
"Okay." After sending the message, Tang Si raised his head and glanced at his elder daughter: "Thank you for your cooperation today. We will do our best to return the truth about Liu Zhong's death."
......
After the questioning, the family left the police station.
Tang Si opened the door and entered the office.
"How?" he asked.
Song Yi sat on a chair: "It has been found that Liu Zhong's personal doctor is Liu Yu, who is Liu Zhong's cousin. It is true that he went abroad by plane two days ago."
"Does this doctor have any questions?" Song Yi asked.
"The biggest problem is him." Tang Si: "As a doctor, you should know how Du Lengding uses medicine. But Liu Zhong is not allowed to restrain him."
He twisted his eyebrows, sat on the sofa, raised his head slightly and closed his eyes.
Song Yi felt distressed, but couldn't help it.
"Ring, ring, ring—" Zhou Liang called.
"Boss, Liu Zhong's youngest daughter was seen when I was on a blind date. The young girl is not like a naive child. The possibility of destroying the restaurant's green plants by herself is very small." Zhou Liang: "Drip Water Guanyin is their newcomer. The clerk bought it. She didn't know it was poisonous. She bought it online."
"Okay, I see." Tang Si: "You send someone to follow Liu Zhong's eldest daughter. Please inform me if you have any information."
Hang up the phone.
Song Yi sat beside Tang Si without speaking, just accompanied him quietly.
Time did not know how long it had passed, Tang Si stood up suddenly: "I have to go."
"I'm with you." Song Yi also stood up.
She is very worried about Tang Si's state now, even if there is nothing wrong with Tang Si now.
"it is good."
Tang Si finished speaking and walked out.
But along the way, it was silent, and neither of them spoke.
Song Yi kept staring at the expression on Tang Si's face, thinking about it.
He drove the car, his thoughts drifting far.
Holding the steering wheel tightly, it looks so much...
This case is too similar to his back then...
When he waited for the traffic light, he was stuck in his thoughts.
"Tang Si, it's the green light."
