An An grabbed Chang Ping's collar and dragged it away, ran two steps and felt that his hand was light, Chang Ping's collar was pulled off, threw away the collar and dragged his arm to the edge of the death zone, because the speed was too fast, dust and smoke came from behind.

An An put Chang Ping out of the edge, breathed in the fresh air and woke up.

Chang Ping sat up and shook his head: "How long have I been in a coma?" ”

An An looked at the place where Chang Ping had fainted and replied, "Less than a minute!" ”

Chang Ping glanced at the place he had just arrived: "Lying grass, it's really amazing, I put me down after taking a sip, it's more vicious than laughing and half a step crazy!" ”

An An looked at him suspiciously: "What is it that is smiling and half-step?" ”

Chang Ping stood up and patted the soil on his buttocks: "A poison, once you take it, you will laugh wildly, and you can't take a step, and you will hang up if you take a step." It can be described as a must-have medicine for killing people and overselling goods! ”

An An was very interested: "Do you have it?" Where can I buy it? ”

Chang Ping shook his head: "I don't, I don't know where to sell it, I've only seen it once on TV!" ”

An Anhu frowned suspiciously: "On TV? ”

Chang Ping nodded: "Yes, the old lady in Washington in "Tang Bohu Dots Autumn Fragrance" used it for Tang Bohu!" ”

"Smack", An An kicked Chang Ping's ass: "Die!" ”

"Ahh Chang Ping flew into the death zone with his teeth and claws, "pop", and lay on the ground, wanting to stand up, but when he shouted, he gasped, so his head was dizzy and he fell to the ground again.

An An kicked Chang Ping out only to find that he had kicked in the wrong direction, and as soon as Chang Ping landed, she ran over again, pulling Chang Ping's leg and dragging him out.

Chang Ping turned over and stood up, glared at An An and roared: "I'm rubbing, you want to murder!" ”

"I said I kicked in the wrong direction, do you believe me?" An An said with a puffed mouth, tears appeared in his eyes, "I was born and died with you again and again, and you still scolded me?" Do you still have a conscience? ”

Chang Ping looked at An An, with a black line in his head. I'm rubbing, what is this goblin going to do? Could it be poisoned too? No, I must have fainted from poisoning, could it be that I was evil?

Tears the size of soybeans flowed down An An's face, looking very aggrieved and pitiful.

"That's it! All right! I was wrong! Chang Ping frowned and quickly apologized. Say cry, cry, is a woman really made of water? Besides, it's not me who is wrong, why should I apologize?

An An wiped her tears and glanced at Chang Ping slyly, thinking to herself: Hmph, little look, fight with me, dare to fight with me, I will dare to throw you into the death zone and ignore you.

Chang Ping sniffed and touched his head: "The smell here is too big and I can't smell anything, I have to try it in another place!" As he spoke, he looked into the mountain stream.

An An waved his hand: "Then let's go quickly, let's go back and rest early when it's done!" ”

Chang Ping looked at An An who was walking in front, he felt that there must be something abnormal about the other party being so positive, but he couldn't think of what the other party was for.

The two of them walked in for more than a kilometer and stopped, still An An stayed outside, Chang Ping went inside, this time Chang Ping was much more cautious, he didn't dare to go too deep, as long as he smelled the smell.

"Hiss", he kept holding his breath, and only took a breath when he walked into the mountain stream, and a smell similar to gas entered his nose, and before he could react, his brain instantly fell down dizzily.

An An put on a gas mask and ran down, the speed was very fast, he jumped two or three meters, and in an instant, he reached Chang Ping's side, grabbed his clothes with both hands and carried them on his shoulders and ran back.

Chang Ping lay on the ground for more than ten minutes before he woke up, his eyes were a little sluggish, as if the gas had anesthetized his brain.

An An breathed a sigh of relief, she didn't expect Chang Ping to fall so quickly, and when she rushed over, Chang Ping had already closed his eyes.

Chang Ping took a big breath, felt that there was no taste in his mouth before he sat up, and looked at the bottom of the mountain stream with palpitations, if An An slowed down a little longer, he estimated that it would be over.

An An looked at him with concern: "What do you feel?" ”

Chang Ping shook his head: "I'm still a little dizzy, it's much better than before!" ”

An An asked curiously, "What taste?" ”

Chang Ping frowned and thought about it for a while and said: "It's a bit like gas, but it's different, and it's a little spicy, it's quite choking!" ”

An An pondered for a while and said, "Could it be that there are other gases in the gas?" ”

Chang Ping nodded: "It's possible!" But you can try! With that, he stood up and opened the package, took out the igniter from it, found some hay from the neighborhood, put on a gas mask, and walked down.

An An stretched out his hand and grabbed him: "You just go like this?" ”

Chang Ping looked at An An in surprise and nodded: "Yes, otherwise?" ”

An An rolled her eyes: "If there is a big gas pit below, can you still run if you light it?" ”

Chang Ping's brain sweated instantly, yes, if there is an explosion, he can't run, what kind of test is this, it's completely fatal!

took off the gas mask and looked at the place more than ten meters away, then looked at the hay in his hand, lit it and threw it down? I can't throw it away! By the way, just bale a stone with hay and throw it down. As soon as he thought of it, he found a stone and wrapped it in hay, lit it, and threw it down.

"Whew", as soon as he threw it out, the fire was extinguished, the stone fell, and after rolling a few times, it didn't even light a cigarette.

An An found some hay and threw it on the ground: "You make a big ball out of hay, and roll it down after lighting it, there is hay inside and out, the more you roll, the bigger the fire, and it will definitely not be extinguished in the end!" ”

Chang Ping gave An An a thumbs up after hearing this, packed a handful of hay nearby and put it on the ground, first rolled it into a ball with a handful of hay and then wrapped the hay on it, wrapping it around and around it, and it didn't take long to make a grass ball the size of a football, but he was worried that the gravity of the ball was not enough to roll, so he wrapped all the remaining hay on it.

A grass ball with a diameter of more than 40 centimeters stepped on Chang Ping's feet, lit it with an igniter, and kicked it out.

"Rustling", the grass ball rolled down the hillside, the more it rolled, the bigger the fire, and soon rolled into the ditch, the grass ball turned into a fireball, and the imaginary explosion did not happen.

Chang Ping stared at the burning fireball and frowned, indicating that the gas in the death zone was not gas, not even a flammable gas.

The gases that can make people instantly stunned are ether, laughing gas, enflurane, isoflurane, sevoflurane, desflurane, and ether is flammable, so it is definitely not ether. (Because the plot needs it, so a brief introduction, I hope you don't use them to do illegal things after reading them, after all, they hurt others and yourself)

Laughing gas, also known as nitrous oxide, has been included in the country's criminal code as a drug

(This chapter is not finished, please turn the page)

, because after inhalation, it can make people feel euphoric and can't help laughing. It can also burn under certain conditions, so it can also be excluded.

Anflurane has a special odor and is mostly used for clinical anesthesia, which is very similar, but unfortunately I haven't smelled it and don't know what it smells like, so it's hard to find some to try?

Isoflurane is a colorless clear liquid with ether-like odor, corrosive effect on metals, rubber and plastics, boiling point 48.5 °C, used for general and hemibody anesthesia in various surgeries. It is not flammable and does not explode, but at that time there was no smell similar to ether, which can also be ruled out.

Sevoflurane is a colorless, transparent, aromatic, non-irritating liquid, which can also be ruled out.

There are sequelae after inhalation of desflurane, which can produce headache, bradycardia, hypertension, sinus arrhythmia, tachycardia, nausea, vomiting, increased salivation, suffocation, dyspnea, increased cough, laryngospasm and conjunctivitis. I didn't have this symptom after waking up, so I can rule it out.

The same exclusion, in the end, only enflurane is the most likely, but it is not easy to get, you can only go to the hospital to ask, if the doctor does not prescribe it, you can't buy it.

An An looked at Chang Ping's brows and stretched a little and asked, "Did you think of anything?" ”

Chang Ping nodded: "I think of one, but I have to go to the hospital!" ”

An An stood up and looked at him: "Then let's go!" ”

Chang Ping shook his head: "Actually, you don't have to go, just find someone to ask!" As he spoke, he took out his mobile phone, found a forensic doctor he knew when he was a police officer from the address book, and dialed it.

After the phone was connected, I didn't expect the other party to remember, and after a few simple greetings, I consulted, and the answer given by the other party made him negate the only remaining guesses.

He hung up the phone and looked at An An, and said with a wry smile: "It's not!" "What the hell is his grandmother's? Could it be mustard gas or hydrogen cyanide? Silently shook his head, no, mustard gas has the smell of mustard, and hydrogen cyanide is flammable.

An An sat on the ground leaning on her backpack: "Then what should I do next?" ”

Chang Ping got up and looked at the bottom of the ditch: "Let's go down and see if we can find some clues from inside!" He put on a gas mask as he spoke.

An An looked at Chang Ping: "I suggest that you go inside, I walk on the periphery, in case the gas mask doesn't work, I can still save you!" ”

Chang Ping nodded: "Okay, then I'll go down, you're on top, once I fall, you will go down to save me!" ”

An An nodded, Chang Ping went down to the bottom of the ditch, looked left and right and didn't find anything unusual, so he had to walk forward, took a few steps and glanced at An An and suddenly fell down.

An An's heart instantly lifted, oh my God, the gas mask really didn't work. Dodged down to the bottom of the ditch, dragged Chang Ping up the slope, felt it with his hand under his nose, he didn't even breathe, and then lay on Chang Ping's chest, "Bang", the sound of heartbeat sounded, although it was beating very slowly, as long as it beat, there was not much danger.

Chang Ping suddenly woke up and choked his neck in pain, looking like he wanted to breathe but couldn't breathe: "Quick!" Fast! Give me artificial respiration! ”

An An looked at him eagerly and asked, "What's wrong with you?" ”

Chang Ping pouted: "The poisoning is too deep, save me!" ”.......
