Luo Huijing, married, 36 years old, is an expert in chemical toxicology with a certain status in the world. I usually live in the United States, and this time I went back to Ghost Island to visit relatives, and by the way, I was invited by my alma mater to give a speech. For this reason, the school also specially sent an invitation letter to her classmates that year, and Chen Mo was one of them, and the date was just two days later.

Chen Mo wanted to find someone to test what the wastewater was, he didn't have so much time to wait for the official inspection report, and now it was up to this "old classmate" to help.

However, Chen Mo has no impression of this classmate, after all, it was more than 20 years ago. Chen Mo found the graduation commemorative album of the middle school, and only then did he vaguely think of the quiet and inconspicuous girl.

At this time, in the full-page headshot, Chen Mo noticed another girl's photo.

It was the first girl he fell in love with, but he didn't confess, so he could only be regarded as a crush.

In the first few years after graduation, Chen Mo always remembered her, but after so many years, Chen Mo hadn't thought of her for a long time.

I don't know if she's doing well now, will she come to this speech?

Youth...... , Chen Mo found that he still had some memories.

The speech was held on Sunday in the auditorium of the middle school near Mr. Chen's home.

Because Ms. Luo Huijing is also a celebrity, the school has more or less publicized it, so there were really a lot of people that day, in fact, you can enter without an invitation, most of them are students and their parents to participate.

On the stage, Chen Mo saw Ms. Luo Huijing, who had a successful career, her face was much more mature than when she was in middle school, and she was full of confidence and arrogance.

In contrast, what should Chen Mo say...... The defeated dog of life?

There was no seat on the invitation, so everyone just found a place to sit. Chen Mo looked around, they were all people he didn't know, so he wanted to find a place to sit down.

At this moment, Chen Mo was patted on the shoulder.

"You're Chen Mo, right? You don't seem to have changed much. 」

The person who came was a man in his thirties, and he was very enthusiastic and talked to Chen Mo.

"Are you ......" Chen Mo looked at the other party, his face seemed to be a little impressed.

"It's me, Xu Chengxing, do you remember?"

"You've changed a little bit, and you didn't recognize it for a while. Chen Mo smiled.

This is a friend who Chen Mo can still talk to a few words when he was in middle school, but he gradually broke off contact after graduating from middle school.

"There's no way, after leaving society, there is pressure everywhere, work pressure, family pressure, and people will age quickly. 」

The other party naturally hugged Chen Mo's shoulders, and Chen Mo did not resist. Chen Mo is not good at socializing with others, but he is not resistant, and he is quite open to people who are more familiar.

"Married?"

"There have been two little mischievous mischiefs. Xu Chengxing had a fatherly smile on his face.

"Congratulations. 」

"What about you?"

"Not yet, fate hasn't arrived yet. 」

"Come on. Come on, the old classmates are all over there, and they plan to go to the dinner party after the end, so you can come too. 」

"Okay. 」

Chen Mo and Xu Chengxing walked to a corner of the venue, where there was a card that read "Three Years and Seven Classes", which was the class from which Chen Mo and his classmates graduated.

Here, Chen Mo saw many familiar faces.

Some people are fat, some people are thin, the same thing is that they are no longer green, and their faces are full of traces left by the years. However, among these people, there was no one Chen Mo wanted to see.

Some people recognized Chen Mo, but most of them didn't remember it, and after hearing others mention it, they vaguely remembered the hot-blooded boy who was warned by the tutor in class.

"Of the fifty-four people in the class, only twenty-five came, less than half. Xu Chengxing sat down next to Chen Mo, with a sigh in his mouth, and then asked Chen Mo, "Then what are you working on now?"

"My boss who used to work ran away and stayed at home for the past two years. Chen Mo didn't have anything to say to others.

"Back then, you had such a sense of justice, we all thought you would be a police officer in the future. 」

"At that time, I was young and didn't know the reality, besides, can the policeman who has a sense of justice live now?"

"Haha, that's what I said. They're not teenagers who don't know anything anymore.

After continuing to talk for a while, the speech began.

As usual, the opening ceremony was a long speech by the Governor, followed by a speech by Ms. Luo Huijing. The content of the speech was the harm of food additives to the human body, some experiences in middle school, and gratitude to his alma mater, and finally ended with an inspirational speech, and the audience applauded continuously.

When Luo Huijing came over, many people rushed to greet her. Then a group of people came to a cafeteria not far from the school.

More than 20 people were divided into three tables, and this meal was quite enjoyable, of course, everyone divided it equally at the checkout, but it was not a high-end restaurant, so it didn't cost much.

Many people met again in private, and even Chen Mo received several invitations.

After everyone dispersed, Chen Mo found an opportunity to talk to Luo Huijing.

"Hello, Ms. Luo, I don't think you remember me. 」

"Are you...... , you are Chen Mo! There really hasn't changed much. 」

Chen Mo was a little surprised and said, "Fortunately, living alone, there are fewer worries. 」

"Is there anything wrong with you?"

Luo Huijing's words are polite, but they also make people feel a little alienated. But Chen Mo didn't care, anyway, the two sides were originally strangers.

"After listening to your speech, I have a question for me. 」

"Please. Hearing that she was not here to climb the relationship or ask for help, Luo Huijing was much more polite.

"What kind of chemical I want to ask is that it is so corrosive to bioenergy?"

"Strong acids and alkalis will ......"

"You're mistaken, I'm not talking about that kind of general thing, I want to ask what kind of chemicals can make a good plant look like this in a very short time. 」

Chen Mo pointed out the photo on his phone.

Where the black dog had passed, all the plants had corrupted into black mud along the way, and it took the villagers a lot of work to clean them up. Chen Mo also took some photos at that time, but he didn't expect it to come in handy.

Some of the corrupted plants still have their original shape on the outside, which is easy to see when compared to the green plants on the side.

Looking at that photo, Luo Huijing frowned a little.

"Old classmate, where did you take this picture? 」

Luo Huijing clicked on the photo and saw that a photo was taken of the corpse of a big yellow dog, most of the fur on the dog's body was rotten and visible in the flesh, just as she was about to look at it, Chen Mo took the phone away.

"I'm sorry, but there's some personal stuff in there, so it's not easy for people to see. 」

There are a lot of photos of the cat people village and the villagers in the mobile phone, as well as a few videos, which are not allowed to be seen by others.

"Where the picture was taken, I can't say. However, there is this kind of thing in the industrial area that is discharged from factories, and I am just curious to ask. 」

"Really?"

"Do you know?"

"Chen Mo, can you please take me to that place? Luo Huijing's expression became serious.

"Yes. 」

After that, Luo Huijing made a phone call: "Xiao Wu, C substance has appeared. 」

The other party seems to have some secrets, but Chen Mo also has it, doesn't he? And this matter seems to be more troublesome than Chen Mo imagined.

Since Luo Huijing seemed to be waiting for her assistant to come over, during this time, Chen Mo and Luo Huijing waited in a nearby coffee shop.

Luo Huijing is not alone, there are two entourages, a man and a woman, who seem to be bodyguards.

"This thing, is the C substance you are talking about?" Chen Mo pointed to the photo on his phone.

"The code name is C starting with corrosion, which is a mysterious substance that has suddenly appeared on the market in recent years. It has a miracle effect in industrial use, whether it is the electronics manufacturing industry, the metal industry, the chemical industry, the demand of all parties is very large. But the problem is that substance C is so toxic that it can cause irreparable damage to the land, so many countries now list it as a contraband. 」

"But in the case of Ghost Island, it's still legal, right?"

Onijima has always been procrastinating, always waiting for things to happen before starting to save them, if nothing happens, then maybe there will never be a relevant decree, and politicians should not see it.

"I don't know about that. However, my place of work is tracking down substance C, and I'm sure they'll take care of it. 」

"Tracking?"

"The formula of substance C is very mysterious, no one knows how it is made, and most of the factories that produce it are in relatively backward or war-torn countries, and the source is not easy to trace, so I really didn't expect to encounter it here. 」

"Uh-huh......

Chen Mo was thinking, what would be the relationship between the demon and the C substance.

In that world, there should also be a phantom land projected by that industrial area, so it is likely that the demon was infected by substance C and had an anomaly. It's just the black energy emanating from the C substance, and Chen Mo feels that this thing doesn't seem to be so simple.

After waiting for more than an hour, Chen Mo and the others waited for a ponytail woman driving a van.

"This is Jiang Wuli, my student. 」

"Hello. Chen Mo nodded and said hello.

The other party reluctantly responded, and couldn't wait to ask Luo Huijing.

"Teacher, is it really? Is there really a C substance in this place?"

"I'm not sure yet, that's why I'm asking you to bring your equipment to check it. This is my middle school classmate Chen Mo, who found out. Next, I'll trouble you to take us there. 」

"No problem. 」

It's the same riverside path, but this time it's much more lively.

"Wow, it's really polluted here. 」

Seeing the surrounding environment, Jiang Wuli suddenly screamed. But after all, it's a chemistry, and I don't complain about the pungent stench here.

"It's the water outlet. Chen Mo pointed to the hidden place of the river defense.

"You're amazing, uncle. This secret pipe is so hidden, to say that there is no ulterior matter, I don't believe it. 」

The road was four meters higher than the riverbed, and it took them some effort to get a sample.

Next, Luo Huijing and Jiang Wuli, a pair of teachers and students, were locked in the truck and didn't know what they were busy with, and it took about half an hour to reappear.

In the chemical factory in the distance, someone began to look at Chen Mo's side.

Chen Mo saw Luo Huijing who got out of the car, and asked, "What is the result?"

"Although the amount of wastewater is very small, it is indeed a substance C. 」

Luo Huijing then looked around and said, "Generally speaking, the area around the C substance manufacturing plant will produce very serious pollution. But this land has been polluted for decades, and the creatures that can survive have become quite resistant, so no one has noticed. 」

At this time, Jiang Wuli also got out of the car: "Uncle in this environment, you can actually find out, it's really amazing." 」

"Somewhat. At first, I was just curious, but I didn't expect it to be such a dangerous thing. 」

"In the picture you showed me, it was substance C with a very high purity, and the dog was also an animal infected by substance C. Can you tell me where that is, and if you don't deal with it quickly, a very serious disaster will happen. 」

Luo Huijing began to feel nervous about Chen Mo's mobile phone photos at this time.

"What photo?" Jiang Wuli asked curiously.

"Don't worry, that's all taken care of. 」

"Really, how is it possible, at this stage, there is no effective means of pollution caused by substance C in the world. Luo Huijing asked in surprise.

"That's a personal secret of mine. Chen Mo said with a wry smile, he didn't expect a photo to cause problems.

"If so, please tell me, it will help a lot of people. 」

"Yes, uncle, if you really know the method, please tell us. 」

Jiang Wuli rolled up the sleeve of her left hand at this time, and her arm, which should have been white, was covered with terrible black scars.

"This is a scar left by the accident of the substance C experiment, and there is no cure for it so far. Uncle, there are many people in this world who are like me. 」

"It's not that I don't help, it's that the method says that you can't do it. 」

"We have the best people and labs in the world, and we have a lot of money to support them. Jiang Wuli said in high spirits, it seems that the origin is not small.

"None of that works, little one, there's only one condition for this method. 」

"What is it? I believe I can do it. 」

"Then you should go and become a magical girl first. 」

As soon as Chen Mo's words came out, the atmosphere between the three of them suddenly became as cold as the North Pole.

"Uncle, are you playing with me?" Jiang Wuli was like a volcano, faintly about to burst out.

It sounds like this sentence is quite ambiguous......

Chen Mo thought for a moment, then took out a bamboo tube from his backpack and handed it to Jiang Wuli. Seeing that she didn't accept it, she handed it to Luo Huijing again.

"Wipe her arm with what's inside, and in a few days you can see how it goes, and then try to see if you can make it yourself." Of course, you can also be a madman and throw things away. This is just an opportunity to reward you for solving this problem without any other ideas. 」

After Chen Mo finished speaking, he didn't leave any contact, and just rode away.

"Teacher, who the hell is he?"

Jiang Wuli had doubts in her heart, he thought that the other party was a liar, but he didn't look like it.

"It was a man whose heart was once filled with righteousness. I thought the righteousness in his heart was dead, but now it seems that the flame of righteousness in his heart has not been extinguished. 」
