"What happened?"

The store manager and a few waiters walked over quickly, and when they saw this scene, their faces turned white, and they hurriedly shouted: "Is she suddenly ill, hurry up and call an ambulance, hurry up!" ”

"It's too late!"

Xu Yancheng raised his head, his handsome face was extremely cold, his dark eyes showed a sharp light, and he muttered: "The chest is tight, it is difficult to breathe, the mouth has the smell of bitter almonds, the heart rate is increased, the skin and mucous membranes are cherry red, and the whole body has paroxysmal spasms...... It's ......"

"Acute cyanide poisoning!"

Cyanide, one of the most toxic chemicals and the most toxic and lethal chemical, requires less than a gram to kill the average person in 15-30 minutes.

As soon as Xu Yancheng's words came out, it was like a bomb thrown into the crowd, and it exploded with a bang.

"What, cyanide poisoning?"

"How can this happen?"

Someone questioned: "How do you know?" ”

"I'm a medical examiner!" Xu Yancheng spoke.

He Zheng's eyes flashed: "Since it is acute poisoning, then the source must be in this coffee shop, and there is something wrong with the coffee she drinks!" ”

The crowd became even more flustered, looking at the cup of coffee that was smashed to the ground, and shouted: "The coffee in this coffee shop is poisonous!" ”

"Oh my God, are we going to be poisoned too!"

"How dare you poison your coffee, what kind of black shop are you!"

The guests were shocked and angry, and some of them had already rushed forward and raised their fists.

The store manager tried to explain in a trembling voice: "Please calm down, our store is absolutely not poisoned, by the way, call the police immediately, call the police!" ”

"Don't mess around." He Zheng's eyes swept over everyone calmly, "Cyanide works quickly, if the coffee you drink is poisonous, it would have collapsed by now." ”

Only then did everyone feel a little relieved.

The store manager quickly called the police.

At this time, Xu Yancheng lifted the woman up, put his abdomen on his knees, broke the woman's small mouth, pressed the base of the woman's tongue with his fingers, and patted her back at the same time.

This is emetic.

With a "wow", the woman spat out some coffee mixed with stomach acid, but her condition did not improve much, and breathing seemed to be extremely difficult.

This is because the cyanide toxin is able to cause rapid hypoxia in the body's cells.

"Get out of the way!" Xu Yancheng shouted loudly, and the crowd around him retreated in fright, revealing a small open space.

Xu Yancheng put the woman flat on the ground.

His hands pressed hard against her rapidly heaving chest, and at the same time, despite the sour smell of gastric juice in her mouth, he gave her artificial respiration.

At the same time, he spoke quickly, and said without looking back: "He Zheng, go to my car and bring the medicine box in the trunk." ”

He Zheng walked out quickly.

About half a minute later, He Zheng returned and handed a dark black box to Xu Yancheng.

Xu Yancheng opened the box, there were two layers inside, the first layer was placed with various test tubes and medicinal liquids, and the second layer was some simple medical equipment.

He dispensed the medicine and moved like a fly.

The crowd couldn't understand it, so they could only talk endlessly, and some people quietly took out their mobile phones and began to take photos and videos and post them on the Internet.

Suddenly, someone questioned: "If it's not the coffee shop, why is there cyanide in her coffee?" ”

He Zheng narrowed his eyes and swept over everyone: "Naturally, someone has moved her hands and feet in her coffee and put cyanide in it." ”

Hearing this, everyone's hairs stood on end, and they were shocked to the extreme.

Who will do it?

Who is so cruel as to throw poison in the coffee of such a beautiful girl!
