We never saw the Poison City people wearing gas masks, and I found several bodies in the room with the window on the door, all of them shot dead.

The men who tried to capture me had shot in the hallway, and they probably killed them.

The corpses, all wearing helmets with air filtration on their heads and chemical suits, were locked in their rooms, and they were supposed to be the staff here, but they were quarantined for unknown reasons.

When I went out, Gu Yu was talking to the eldest brother of those people, and Gu Yu dragged people to the flower bed by the square, where there was no body.

When Gu Yu saw me come out, he pointed to the sky, and I looked up in the direction of his finger, and saw a purple cloud parked above the city, propped up like a parasol over the city.

It turned out that all the poisonous gases discharged by the exhaust system floated to it, and so did the poisonous fog on the ground, as if all of them had turned into water vapor, converging over the city and forming a cloud of poison.

"The poisonous gas has not dissipated, and the problem should not be with the poisonous insects."

"Is it geothermal?"

"Possibly, it's better to have a heat source under the slag."

"I'll go."

"No, you look at them."

"Don't fight with me about this, the temperature underground is too high, the gas mask can prevent poison, but it can't prevent heat, I'm fine, you know."

Gu Yu uttered a syllable, obviously wanting to say something, but I was interrupted first: "I don't know how to interrogate, our division of labor and cooperation are efficient." ”

He looked down at the 'big brother' on the ground, sighed and compromised, "Then you should be careful." ”

"Okay~" I smiled and gestured to him OK, hoping that my confident smile would make him worry a little less.

In fact, many times it is not that I want to be strong, but the objective conditions are like this, I can recover quickly from injury, but Gu Yu and they can't.

It is precisely because Gu Yu knows this that he has no choice but to compromise, but he must feel uncomfortable, but we are not just doing things for ourselves, since we have chased to the poison city, we can't give up halfway and leave without understanding the situation.

I returned to the ground and saw Hu Tao running out in a hurry, gesturing at me as he ran: "There is a hole underneath!" ”

"What hole?" I took a few quick steps to catch him.

"There's a hole in the pool, there's a hole in the bottom of the pool." Hu Tao said angrily: "There is still something down there, it's too hot, I can't get down." ”

I was anxious to see what was down there, so I ran along, even ahead of Hu Tao.

Five or six meters away from my room, I felt a wave of heat hit my face, and the temperature was several degrees higher than before.

"It's too hot, at least 50 degrees, the exhaust system doesn't work, and there's no air conditioning down there."

"You wait here, I'll take a look."

"No, I'm responsible for your safety."

"You wear a mask, if you get dizzy when you go in, I still have to carry you, so, tie a rope around my waist, if I faint, you pull me out, I'm not afraid of poison, don't fight with me."

After I finished speaking, I didn't know the bottom of my heart, I was usually used to being strong, Hu Tao was not familiar with me now, and I was worried that he would not listen to me.

Fortunately, he didn't insist, and went to find a rope, I tied one end of the rope around my waist, and this time I didn't take off my coat, the floor was so hot that in case I really fainted to the ground, I dressed thickly so that I wouldn't get burned.

The sound of the exhaust system not stopping, the fire and smoke in the pool were gone, and I walked to the edge of the pool and found a big hole leaking at the bottom.

Or maybe it's not a leak, but the hole is already there, but we burned it when we burned it.

Now the great hole was exposed, and the scorching heat was pouring up from below, and when I looked down, I saw a pile of stones that glowed faintly purple.

I've seen a source stone that glows blue, and I wonder if this purple stone also contains strange energy.

I looked at the corpse by the wall, picked one at random, walked over, cut off the corpse's fingers, and threw it into the pool.

My finger fell on the purple stone, and within a few seconds there was a sizzling sound of roasting meat, and I said to myself, sure enough, it was these stones that were hot, they were self-heating bodies, and there was no way to extinguish them with water.

Besides, the whole city is heating, this pool is just a small hole, I don't know how many such heating stones there are in the ground, unless the whole city is shoveled open, let it come into contact with the cold air to cool naturally, otherwise there is no refrigeration equipment to cool the whole city.

But my concern is not the heat, the people of the poisonous city raise poisonous insects on the hot stones, and the colors of the two are highly uniform, and it is difficult for me not to associate them.

So what I'm worried about is whether the hot stone will warm up more toxins and promote the reproduction of viruses, after all, the poisonous gas comes from the living body, it is considered a microorganism, and now all the poisonous gases are condensed in the sky, and their threat has not been lifted.

We didn't know about hot stones and poisonous insects, but someone did, so I thought in a different direction, quickly exited the room, and went to the office I had visited from memory.

This place is not a research institute, just a large drug factory, and the important information must be with the boss.

Hu Tao saw me running out in a hurry, thinking that something was wrong, although he couldn't see his expression, but his tone showed panic: "Are you injured?" ”

"No, I'm going to the office, you go up first, it's getting hotter and hotter, you're going to be starved of oxygen."

"What if you faint when I'm gone, no-"

"You drag the rope to the top of the stairs, it's cooler, and if I don't move in ten minutes, you can drag me out."

Hu Tao's breathing has become heavy, he is still wearing a down jacket, and if he stays any longer, he will not only lack oxygen, but also become dehydrated.

The gas mask is like a leather hat, but he can't take it off, and the feeling of wearing a padded jacket on dog days must be more painful than wearing pants on dog days.

Hu Tao nodded, pulled the rope and walked out, I pushed the door into the office, the inside was different from the outside, the things were neatly placed in place, there was no clutter, and there were no dead bodies.

I quickly rummaged through desks, bookcases, filing shelves, and even under desks and behind sofas, not missing a single corner.

Unfortunately, nothing was found, all the paper with words had nothing to do with hot stones and poisonous insects, the owner of the room had saved a bookcase of foreign classics, and the file shelves only had employee attendance sheets and production plans.

I didn't give up, and I conducted a second round of searching, this time by direct force, and finally I found the secret compartment in the drawer.

There was a work notebook in the dark compartment, I didn't open it when I took it, it was too hot in the room, I rolled up the book and ran out.

When I arrived at the staircase, Hu Tao was about to pull the rope, and when he saw that I came out, his shoulders were obviously loose.

We went back to the ground together, Gu Yu was still talking to the 'big brother', I waved at Gu Yu, "Let's go, go out and talk." ”

After some tossing, I was so hot that I was about to suffocate, and I was anxious to cool down, Gu Yuliu Hu Tao looked at a few people on the flower bed and went outside the city with me.

When I stepped out of the geothermally covered area, the air instantly became cold, and I shivered with the alternation of hot and cold, but when I breathed in the cold air, my drowsy brain immediately cleared up.

I took out my work notes and said, "I found this, hidden in the secret compartment of the office drawer, and I haven't read the contents yet." ”

"Where's the heat source, have you found it?" Gu Yu took the notebook and flipped it over.

"It's a kind of hot stone, and the poison city should be full of this kind of stone, and there is no way to cool it artificially."

Gu Yu opened the notebook and read a few pages carefully, then closed it and handed it back to me: "You keep it, the things recorded here are very important, look back and look back, find a place to clean it up first, we have been out for too long, Long Tao and Chen Dong will be worried." ”

Although Gu Yu and Hu Tao entered the city later, they were also stained with a layer of poisonous fog on their bodies, and now we can be sure that the toxins invade the human body through the respiratory system, so as long as they change their clothes and wipe off the toxins on their gas masks and skin.

The toxins in the city are all floating in the sky, and at this time, if you take off the mask, you won't be poisoned, and when Gu Yu and Hu Tao finish cleaning up, we will go out of the city.

Hu Tao took a big breath of the cold air outside the city, took a few breaths and didn't seem to be enjoyable, and then picked up a snowball from the side of the road and covered it on his head.

"What did you ask?" Gu Yu chatted with the 'big brother' for a long time, and he must have asked something, I asked as I walked.

"Those people are also drug dealers, but they are offline distributors, they came to buy goods today, and when they saw that something was wrong in the city, they wanted to pick up a leak, usually they didn't have the opportunity to enter the underground factory, thinking that it was full of drugs, but I didn't expect that drug trafficking was just a guise for a drug city, and there were no drugs at all."

"They are bold enough to dare to enter the city when they know that something is wrong."

"A weapon that can kill people is also a commodity, so they want to arrest you, and if they have both poison gas and antidote, they won't worry about finding a buyer."

"Yes, if you dare to think and dare to do, you are unlucky."

"Still haven't found the masked poisoner?" Gu Yu asked.

"No, I went from room to room, and there was no box like the one I intercepted, and the situation was very bad."

"We just did our best." Gu Yu's soft tone was obviously comforting me.

"I know, a lot of things are out of your control, hey, my mind isn't that fragile."

"I know, I want to comfort you."

"Then I accept it, I'm so happy~"

"Ahem, cough, cough..." Hu Tao suddenly coughed violently, as if he was choked by his own saliva, and tears came out of his eyes.

"Why, I'm not used to seeing the sudden change in the style of painting and the collapse of the character!" I raised my eyebrows and squinted at Hu Tao.

In the original time and space, Gu Yu and I often fell in love in tense battles, and the style of painting changed when it was said, but Gu Yu in this time and space can be said to have suddenly changed his sex, and the gap between his attitude towards me was too big, and the onlookers were obviously not used to it.

Hu Tao waved his hand again and again, indicating that he was not used to seeing it, but his eyes were staring at the surrounding scenery, but he didn't look at me and Gu Yu.

We didn't bring those drug dealers out, let them fend for themselves, anyway, the drug dens are gone, and they can be said to have lost their wives and soldiers this time.

When I got back to the car, Gu Yu asked me to take out my notes, I took the ball from Long Tao's hand, the car was warm, I opened the quilt that wrapped him, and let him move freely.

Qiuqiu reached out and poked my chin, his big dark eyes staring at me unblinking, and I remembered how worried he had been when I left, so I kissed him on the forehead as a sign of comfort.
