We didn't see the people in the Poison City wearing gas masks from beginning to end. I found several bodies in the room with windows on the door, all of which were shot to death.

The people who wanted to catch me had fired shots in the corridor, and they probably killed them.

The corpses were wearing helmets with air filtration function on their heads and were wearing chemical protective suits, but were locked in the room. They should be staff here, but for some reason they were quarantined.

When I went out, Gu Yu was talking to the elder brother of those people. Gu Yu dragged the person to the flower bed next to the square, and there was no corpse.

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

It turned out that all the poison gas discharged from the exhaust system had floated up on it, and the poisonous fog on the ground seemed to have turned into water vapor, gathering over the city, forming a poisonous cloud?!

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

"Is it geothermal heat?"

"It is possible that it is best to get the heat source under the slag."

"I'll go."

"No, you look at them."

"Don't argue with me about this. The temperature underground is too high. The gas mask can prevent poison and cannot prevent heat. I'm fine, you know."

Gu Yu issued a syllable, and obviously wanted to say something, but I interrupted it first: "I don't know what to interrogate, we have high efficiency in division of labor and cooperation."

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

"Okay~" I smiled and compared him with an OK gesture, hoping that my confident smile would make him less worried.

In fact, many times it is not because I want to show off my strength, but because I am in this way, and I can recover quickly when I am injured, but Gu Yu and the others can't do it.

It was because Gu Yu knew this that he had no choice but to compromise, but he must feel uncomfortable. But we are not just doing things for ourselves. Since we are chasing us 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 hurriedly, and gestured at me while running: "There is a hole underneath!"

"What hole?" I walked a few steps to meet him.

"Cat, there is a hole under the pool." Hu Tao said anxiously: "There is something down there. It's too hot, I can't get down."

I was anxious to see what was below, so I ran along, even surpassing Hu Tao to run ahead of him.

I felt a wave of heat coming from the room five or six meters away, and the temperature rose several degrees higher than before.

"It's too hot, at least fifty degrees, the exhaust system is useless, and there is no air conditioner underneath."

"You wait here, I'll go and have a look."

"No, I have to take care of your safety."

"You wear a mask and feel dizzy when you get in. I have to carry you. In this way, tie a rope around my waist. If I get dizzy, pull me out. I'm not afraid of poison, don't argue with me."

I was unsure after I said that. I was used to being strong. Hu Tao is not familiar with me now, so I was worried that he would not listen to me.

Fortunately, he didn't insist and went to find a rope tie. I tied one end of the rope to my waist. This time I didn't take off my coat, and the floor was hot. If I really fainted and I wouldn't be burned if I was wearing thicker clothes.

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

Or it wasn't that it was leaking, but the hole had already existed, but we burned the filling when we burned the corpse.

Now the hole was exposed, and the scorching heat surged from below. I leaned my head down and saw a pile of stones emitting faint purple light.

I have seen source stones that emit blue light, and I wonder if this kind of stone that emits purple light also contains strange energy.

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

My finger fell on the purple stone, and a sizzling barbecue sound was made in a few seconds. I thought to myself, it was true that these stones were the ones that heated up. They were self-heating bodies and could not be extinguished with water.

Besides, the whole city is heating up, and the pool is just a small hole. I don’t know how many such heating stones are underground. Unless the entire city is shoveled open and it is exposed to cold air to cool naturally, there is no refrigeration equipment that can cool the whole city down.

But what I am worried about is not heat. People in Poison City raise poisonous insects on hot stones, and the colors of the two are highly unified, so it is difficult for me not to associate them together.

So what I am worried about is whether hot stones will warm up more toxins and promote virus reproduction. After all, poisonous gas comes from **, which is considered microorganisms. Now all poisonous gases are frozen in the sky, and their threat has not been eliminated.

We don’t know about hot stones and poisonous insects, but someone knows it. I changed direction and quickly exited the room, and went to the office I had visited according to my memory.

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

Hu Tao saw me running out in a hurry and thought something was wrong. Although he couldn't see his expression, his tone showed panic: "Are you injured?"

"No, I'm going to the office, you go up first, it's getting hotter and you'll be deficient in oxygen."

"What should you do if you faint after I leave? No—"

"You pull the rope to the stairs, it's cooler. If I don't move in ten minutes, you'll drag me out."

Hu Tao's breathing has become heavy. He is still wearing a down jacket. If he stays there, he will not only be hypoxia, but also dehydrated.

The gas mask is like a leather hat, but he can't take it off. It must be more painful to wear a cotton jacket during the holidays than to wear shorts in the 39th day.

Hu Tao nodded and pulled the rope out. I pushed the door and entered the office. The inside was different from the outside. The things were neatly placed in place, without any mess, and there was no dead body.

I quickly searched, my desk, bookcase, document shelf and even under the desk and behind the sofa, without leaving any corner.

Unfortunately, nothing was found. All the paper with words had nothing to do with hot stones or poisonous insects. The owner of the room saved a bookcase of foreign classics, and there were only employee attendance sheets and production plans in the document shelf.

I didn't give up and conducted a second round of searches. This time I directly destroyed it by force, and finally found a secret barrier in the drawer.

There was a work note in the secret compartment, but I took it and didn't open it. The room was too hot, so I rolled up the notebook and ran out.

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

We returned to the ground together, and Gu Yu was still talking to the 'big brother'. I waved to Gu Yu, "Go and go out and talk."

After a while, I was so hot that I was about to suffocate and was eager to cool down. Gu Yuliu and Hu Tao looked at the people on the flower bed and went out of the city with me.

As I stepped out of the area covered by the ground heat, the air suddenly became cold. The alternating heat and cold made me tremble. However, after breathing the cold air, my drowsy mind immediately woke up.

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

"Where is the heat source? Have you found it?" Gu Yu took the notebook and flipped over.

"It's a kind of hot stone. There should be all these stones under the Poison City, and there is no way to cool them manually."

Gu Yu opened the notes and read them carefully for a few pages, then closed them and handed them back to me: "You save them well, the things recorded here are very important. Look back and find a place to clean them up first. We have been out for too long, so Long Tao and Chen Dong will be worried."

Although Gu Yu and Hu Tao entered the city behind, they were also covered with poisonous mist. Now we can be sure that the toxins invade the human body through the respiratory system, so just change the clothes and wipe off the gas mask and the toxins on the skin.

All the toxins in the city have floated up to the sky. At this time, we will not be poisoned even if we take off the mask. After Gu Yu and Hu Tao have finished cleaning up, we will leave the city.

Hu Tao breathed in the cold air outside the city with a few breaths, seemed to be unsatisfied, and then rubbed a snowball from the side of the road to cover his forehead.

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

"Those people are also drug dealers, but they are offline distributors. When they came to purchase goods today, they wanted to find a vacant thing when they saw something happening in the city. They usually didn't have the chance to enter the underground factory and thought that all the drugs were stored inside. Unexpectedly, drug trafficking was just a guise of the drug city, and there were no drugs under them."

"They are brave enough to know that something is wrong and dare to enter the city."

"A weapon that can kill people is also a commodity, so they want to catch you. If they master the poison gas and antidotes at the same time, they will not worry about not being able to find a buyer."

"No, if you dare to think or do it, you will be unlucky."

"Isn't I found a poisonous man wearing a mask?" Gu Yu asked.

"No, I looked at each room, and there were no boxes I intercepted. The situation was very bad."

"We just need to do our best." Gu Yu spoke softly, obviously comforting me.

"I know, many things are not something you and I can control. Hey, my heart is not that fragile."

"I know, I want to comfort you."

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

"Cough cough cough..." Hu Tao suddenly coughed violently, as if he was choking by his saliva, and his tears were coughing out.

"Why, I can't stand the sudden change in the style of the painting and the character collapsed!" I raised my eyebrows and looked at Hu Tao with a squint.

In the original time and space, Gu Yu and I often talk about love in the tense battles, and the style of painting changes as soon as possible. Gu Yu in this time and space can be said to have suddenly changed his nature. The gap in his attitude towards me is too big, and the bystanders are obviously not used to it.

Hu Tao waved his hands repeatedly, saying that he didn't feel uncomfortable with it, but his eyes kept staring at the surrounding scenery, just not looking at Gu Yu and me.

We didn't bring those drug dealers out and let them fend for themselves. Anyway, the drug den was gone, so they lost their wives and their troops this time.

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

Qiuqiu reached out to poke my chin, and his big dark eyes stared at me without blinking. I remembered that he seemed very worried when he left, so he kissed his forehead to show comfort.
