Grady's blue eyes were unsuspecting anger, and the expression on his face was still calm, and he glanced at the three people who were looking at him before he said to Qi Enwei: "This is not what you think. ”

Qi Enwei was skeptical and asked curiously, "Then what is this?" Do you know each other? After she said that, she simply began to open the plastic package, intending to take a look at it first.

At this moment, everyone's attention had already shifted from the rotten fan to Qi Enwei's hand, and by the time she opened the bag, Shi Fatzi had already run to the kitchen and brought a small spoon over.

Qi Enwei was inexplicably a little excited, she took the spoon and carefully scooped out a spoonful of powder, leaned forward and sniffed it: "It doesn't smell good, why don't I taste it?" ”

"Don't get it in your mouth!" Meng Hui hurriedly stopped, "This powder was deliberately hidden in the fan, it shouldn't be something harmless, right?" ”

She couldn't help but glance at Grady, and saw that he had the same curiosity on his face.

Everyone felt that the powder couldn't enter their mouths, so Qi Enwei hurriedly poured the spoon back into the plastic bag and handed it to Meng Hui. "Sister Sasha, take a look, I don't smell it anyway."

Meng Hui leaned closer to the bag and sniffed it, and passed it to Grady. "I don't know what it is."

Grady smelled and looked at the light, and finally boldly pinched a little powder with his hand and crushed it, his brows furrowed into Sichuan characters: "I can't see it, it feels a bit like edible salt." ”

"Who the hell is okay to hide salt in the fan? Sick? Bao Lu didn't bother to look at it, and handed the bag directly to Shi Fatzi.

Shi Fatzi always pretends to know everything and has seen everything by virtue of his age, but obviously his knowledge is limited to all kinds of strange foods, and he doesn't really know everything.

He silently handed the bag to Lan Dong, and to his surprise, Lan Dong was even bolder than Grady, and forgot to stuff it in his mouth after dipping a little powder, which scared everyone to shout again and again.

"It's sodium nitrite. Phew...... ......He hung his head down from the sofa and spit on the ground several times, then smeared the remaining powder on the sofa on his hand, sealed the bag and returned it to Meng Hui.

Even if the five people present no longer understand chemistry, they all know that sodium nitrite is a toxic industrial salt, and excessive consumption will cause poisoning, and if too much is eaten at one time, it will directly lead to death. But everyone couldn't help but look at each other, and it was hard to believe Lan Dong's judgment.

After all, he seemed to be the most unreliable of the six people present. is thin, his cheeks are sunken, his eyes are dull, his facial features can even be said to be a little ugly, and he has no energy, so people can't treat each other squarely.

"Blue, how do you know this is sodium nitrite and not ordinary salt? These two should taste about the same, right? Grady was the first to ask politely.

Lan Dong didn't care about their eyes at all, and responded angrily with his eyes closed: "Unlike salt, the taste of sodium nitrite is bitter, astringent, and slightly salty. Oh, and I forgot to mention, I majored in chemistry in college. ”

Bao Lu sneered: "Hehe, I thought you were a beggar." ”

Shi Fatzi laughed after Hehe, Qi Enwei pursed his lips and snickered, Meng Hui stared thoughtfully at the plastic bag in his hand, and was in no mood to pay attention to the boring jokes of Bao Lu.

She remembered the discomfort she had just finished talking about the suggestion, her mouth was dry, her heart was beating faster, and she was dizzy, she thought it was because she had suffered from heat stroke when she buried Jia Ruyi before, but now that she thinks about it, it shouldn't be the reason.

"Everyone," Meng Hui's face was a little pale, and his throat was a little dry and itchy, "Have you had any sudden shortness of breath, palpitations, and dizziness in the past two days?" ”

Qi Enwei was the first to nod: "Yes, on such a hot day, I feel like I have suffered a slight heat stroke several times." ”

Bao Lu, Shi Fat, and Grady then reported that they had the same symptoms, and they also thought they were suffering from mild heat stroke. When Meng Hui heard everyone's words, he felt a chill down his spine, and he couldn't understand what was going on this mission at all, and a chill arose in his heart.

Everyone had a faint guess in their hearts, and their faces changed one by one, Qi Enwei even kept muttering, "This is impossible", and at this moment, Lan Dong suddenly said weakly: "Someone threw sodium nitrite into the water we drank." ”

Trapped on an uninhabited desert island with no running water, no village in front of the village, no store in the back, no communication and network, the remaining six barrels of mineral water kept everyone calm to a large extent.

Because I knew that there was water to drink, I didn't feel that death was imminent, and because I knew that I could last a week, I was able to stabilize my state and wait for rescue.

But the leftover sodium nitrite in the bag finally broke the last peace.

"Something is wrong, this is really wrong!" Bao Lu's face turned pale, he stood up suddenly, covered his head and roared, "I'm grass!" I grass your ancestors! Who the hell is it! Come out to Lao Tzu! Isn't it you? Are you playing tricks? ”

No one paid attention to him, and the fat man sat on the ground and leaned on the sofa, chanting in his mouth: "Who will harm us...... Who poisoned it...... Why do you want to do this......"

Lan Dong still closed his eyes and didn't speak, but his breathing was a little messy. Qi Enwei hugged her knees against the wooden wall and cried softly, her shoulders shrugged, and her cry was so desperate that she might collapse at any moment.

Relatively calm are still Grady and Meng Hui. One is a criminal who has seen the world, and the other is a prefecture staff member who has died once, and under deliberate adjustment, his mood quickly returned to normal.

"Sha, what do you think should be done now?"

"First of all, we have to solve the problem of drinking water. Whoever poisoned them was, they were definitely no longer on the island, and a few of us obviously didn't have the time to poison them. So I don't think there's any need to dwell on who is the poisoner, at least until we solve the water problem. ”

Grady agreed with her, but his expression was not relaxed: "Where can we go to find water?" Perhentian Island is not big, we saw it when we went out looking for boats, there is no natural water source here. ”

Meng turned his head to look at Lan Dong, whose eyelids were trembling, and his voice was anxious. "Can you find a way to get rid of the toxins in the water? By distillation or something? ”

"Distillation? Snort-" Lan Dong smiled lowly, didn't open his eyes, but said a few words rarely.

"There are four ways to remove sodium nitrite from water: oxidation, membrane separation, ion exchange, and biochemical treatment. All we can do now is biochemical treatment, one of which is to use aerobic organisms...... Forget it, don't bother to explain, go to the sea to find seaweed, clean it and throw it into drinking water. ”

Meng Hui always felt a little unreliable: "Are you sure that this will detoxify?" ”

"Not sure." Lan Dong slowly opened his eyes, a little helpless, "I'm studying chemistry, but I didn't say I'm a scholar." ”
