The waiting hall of the airport is crowded.

Mr. and Mrs. Yang Boming sat on the sidelines and waited quietly to board the plane.

Looking at the strangers coming and going, Yang Boming's eyes were full of loss and melancholy.

He has lived in this city for most of his life, but he didn't expect to leave his hometown when he was old, and he couldn't even keep the scientific research results that originally belonged to him.

"When we get there, let's live some quiet days." Mrs. Yang gently shook her husband's hand with a tolerant smile on her face.

"After all these years, you've been so busy with work that you haven't been with me for a long, long time. Now, we have time, and we can watch the sunrise and sunset together."

Yang Boming patted the back of his wife's hand tremblingly, and there was a trace of tears in his eyes.

In this life, he owes his wife too much, and now he can't take care of himself, but the people around him are always her.

The young girls who once surrounded him and swore that they loved him deeply are long gone.

Mrs. Yang took out a tissue from her bag and wiped the tears from the corners of her eyes for Yang Boming.

He Dongchen's bodyguards stood beside the couple, looking around vigilantly and responsibly.

At this time, a little boy with a small schoolbag and a peaked cap walked towards Yang Boming.

The little boy looked like he was three or four years old, and there were no adults around him, and his bright and clear eyes sparkled, and he soon stood up by his wheelchair.

When the bodyguard saw that it was just a child, he did not stop him.

"Kid, why are you alone? Where's your mother?"

Mrs. Yang looked at the soft and cute little baby in front of her, and couldn't help but squat down and gently pinch his face.

"Are you separated from your parents? I'll help you find them, okay?"

The little boy shook his head and said immaturely, "My mother has gone to heaven, and it will be a long, long time before she returns."

Yang Boming and his wife looked at each other, and they both felt distressed for the little boy.

The little boy walked over and grabbed Yang Boming's two fingers.

He raised his head and looked at Yang Boming, and his innocent smile made Yang Boming's heart melt.

"Grandpa, are you sick?"

Yang Boming couldn't say a clear word, but nodded slightly.

When the little boy heard this, he took out a colorful candy from his small schoolbag and fed it to Yang Boming's mouth.

"Grandpa, eat candy...... My dad said that if you eat it, you will get better."

Yang Boming used to be a big smoker, and in order to quit smoking, he began to eat sugar.

At this moment, he felt that the little boy in front of him was like an angel sent by God, bringing him a candy when he was most helpless.

He couldn't help but feel emotional.

When the little boy stood on tiptoe, he not only stuffed the sugar into Yang Boming's mouth, but also half of his little hand.

"Thank you, little friend." Mrs. Yang touched his head, sorted out his schoolbag for him and put it back on his back, "Where is your adult?"

"Daddy went to the bathroom, let me stay here and wait for him."

Mrs. Yang breathed a sigh of relief, she wanted to hug the little boy, but suddenly, Yang Boming foamed at the mouth and convulsed all over.

Mrs. Yang and the bodyguards were shocked.

She gave first aid to Yang Boming, and the bodyguard immediately dialed the 120 emergency number and sought help from airport staff.

The scene was chaotic.

By the time the bodyguard came to his senses, the little boy was gone.

Yang Boming was rushed to the hospital for treatment, but he died on the way.

When He Dongchen rushed to the hospital, he only saw Mrs. Yang crying heartbreakingly in the corridor.

"Boss, the doctor just told me that Dr. Yang was poisoned."

He Dongchen's pupils shrank, and his brows furrowed. "Poisoned? What poison?"

"It's a long name, I'...... I didn't remember it for a while. However, the doctor said that this poison is not available to ordinary people. The gambling nature is very strong, and the seizure speed is very fast, several

There wasn't much time to salvage. In our country, there has always been a ban on the sale of goods."

He Dongchen was silent for a long time, and then slowly walked to Mrs. Yang's side.

"Mrs. Yang, the festival mourns and ......."

"What did you do? Others say that you, He Dongchen, can fight against death. You have protected so many people, how can you ...... when it is the turn of my old Yang You compensate my husband for me......

Mrs. Yang was already crying, and when she clenched her fists and pounded He Dongchen's chest, He Dongchen stood motionless.

Yang Boming was poisoned to death under his protection, and he really needs to bear the main responsibility.

It wasn't until Mrs. Yang finished venting her emotions that He Dongchen told her what the doctor said, and then asked, "Mrs. Yang, in the current situation, you need to call the police."

Mrs. Yang wiped away her tears, and after calming down a little, she still listened to He Dongchen's advice.

The forensic doctor gave Yang Boming a detailed autopsy and determined that Yang Boming had indeed died of poisoning.

"It's a little strange, how did the poison enter Yang Boming's body?"

The medical examiner questioned this.

"Depending on the nature of the drug, the onset time is one to three minutes after taking the drug. According to Mrs. Yeung, he didn't eat anything during this time."

"Didn't you eat a child who gave me a lay?"

"There's still half of that candy left, I've tested it, and it's not poisonous."

Everyone looked at each other, and for a moment they couldn't come up with convincing assumptions.

After all, it was just a three- or four-year-old child; How could he have poisoned an old man he didn't know?

He Dongchen got Yang Boming's autopsy report through some channels.

Although so far, the police have no conclusive evidence to prove that this incident is related to Yang Moran, but he always believes that Yang Moran is the most suspicious.

Yang Moran is ruthless and cunning, Yang Boming does not die for a day, he will not be able to enjoy the dividends brought by the current scientific research results with peace of mind and peace of mind.

But how did he manage to kill without leaving a trace?

He Dongchen was puzzled.

He called two bodyguards who were present at the time and asked for the details of the situation.

"You look for airport surveillance and check the kid."

"Boss, do you suspect it's the kid?" The bodyguard was dumbfounded, what can a little fart kid do?

He Dongchen looked down at the autopsy report and said seemingly casually: "Children can't kill people, it's hard to guarantee that adults in the family won't."

"Move fast, I think, the police should be looking for this kid too. I'm going to meet him before the police look for him."

"Understood."

The bodyguard retreated, and He Dongchen was left alone in the study.

The sudden silence made him feel physically and mentally exhausted.

He looked at the picture frame on the desk, Yin Qianyue snuggled in his arms, smiling brightly and happily.

He Dongchen picked up the photo frame and sighed silently, he didn't know how long he would have to wait before God would give him a definite answer.
