Having already had dinner in the security hall, Lu Xin went back to the bedroom with a light hand.

The house they live in is a small one with two bedrooms and one living room. Lu Xin usually lives in a second bedroom. Her mother lives in the master bedroom. Her father often stays in the kitchen, while her sister sleeps in the ceiling partition near the door. However, most of the time, she squats on the sofa, holding the bear, Watching cartoons all night.

In the small bedroom, Lu Xin sat down quietly in his room with only one bed, one chair and one desk. Then he turned on the desk lamp and quietly looked through the documents and materials about special pollution and reviewed them briefly.

At the same time, he is waiting for his mother to come back. It's time to have a chat with her.

Since the last factory incident, he has always wanted to talk to his mother, but he has never found a chance.

Recently, mom's whereabouts are a little strange. She often goes out to make new friends.

"Treatment of secondary pollution sources..."

Under the desk lamp that can only light up a small area, Lu Xin silently reviews what he learned today: "the impact of secondary pollution sources... Replace the main pollution sources to carry out the will, affect the surrounding environment... Most of them are the main pollution sources, lack of inner emotions, make up for the formation of... A few cases prove that some pollution sources have the ability to split two or more secondary pollution..."

"The capacity of secondary pollution sources is mostly the extension of the main body, and there is no case to distinguish the two capacities..."

"Treatment method: eliminate the main body of pollution sources and find the logical chain of primary and secondary pollution sources..."

"Independent existence of secondary pollution sources: not confirmed..."

“……”

Lu Xin is more concerned about this part of theoretical knowledge.

The last time he saw the secondary pollution source of No. 039 special pollution source in the factory, he was more concerned, because he wanted to know whether this situation could also explain his current problems to some extent.

Although, on the surface, the secondary pollution source is quite different from itself.

For example, secondary pollution sources can be sensed or even "seen" directly.

And his family, but no way to be detected.

For another example, the secondary pollution source is a bit silly in any way, and there is no way to communicate

And my family, not only can communicate, but also have character

However, although the difference is quite big, it is the closest mental change I have ever seen.

So when he learned this piece, he was particularly serious.

……

……

"Step", "step", "step"

I don't know how long after that, Lu Xin, who was absorbed in learning, heard the sound of heels stepping on the tile floor in the corridor.

He knew that it was mom who came back.

So he got up carefully and gently pushed open the bedroom door.

"Step", "step", "step"

The sound of trampling came to the door, and then it opened gently.

The room began to light up when mom turned on the light.

Wearing a white suit and skirt, a satchel in her hand, a red hat on her head, and a thin make-up on her face, she looks elegant and charming under the dim light. She gently closes the door, takes off her low heeled shoes, and then puts the satchel on one side of the tea table. While changing her slippers, she smiles to Lu Xin: "it's so late, Why haven't you slept yet? "

Lu Xin nodded and said, "yes, I'm waiting for you."

"Oh, sorry, I had a great time..."

With a smile, her mother put her hand on Lu Xin's shoulder and walked into the room together: "Miss Chen is very nice!"

"Miss Chen..."

Lu Xin is very helpless about this.

My mother often makes some friends, but Lu Xin has never met her.

When he first saw the existence of his family, he once wanted to understand his situation very much. At that time, he once asked who these friends were and what they looked like. But his mother just replied with a smile, "I'll introduce you when I have a chance." Then after a while, when Lu Xin remembered and asked again, his mother just sighed.

Anyway, I either went back to my hometown, or I haven't seen it for a long time

……

……

Sitting at the table, mother poured a glass of water and put it beside Lu Xin.

She sat on one side, rubbing her tired legs like shopping, and asked with a smile, "how's your work recently?"

"Very good..."

Lu Xin nodded his head and said in silence: "what happened to the factory in the north of the city last time..."

"Oh, you remember!"

Looking at Lu Xin's serious expression and attitude, her mother laughed and said, "I thought you had something important to do, silly child. I just happened to pass by and saw you and your sister standing there foolishly. There was no way for a little girl to do it. Stupid and lovely, how can I not ask?"

"Passing by..."

This answer obviously does not satisfy Lu Xin.

He was silent for a while, then whispered: "you often go out recently, what are you doing?"

"Going shopping, of course..."

Mother replied with a smile: "although I have to take care of my family, I have to have my own life, right?"

Lu Xin was speechless by this sentence.

In fact, sometimes he also felt that his family, sometimes, was too normal.

In the past, he could not ask any more questions at this time.

Now, after all, he understands a lot of knowledge and theories about special pollution, so he slowly ponders over them, deliberates every word, and asks softly, "is the little girl I saw last time in the factory a real person?"

Mother listened, smiling: "silly child, that is false, just a split out of the spirit..."

Lu Xin nodded slightly, and then said slowly, "what about you?"

When Lu Xin asked this, his father's snoring stopped suddenly in the kitchen.

In the crevice of the ceiling partition, my sister's bright eyes are peeping.

"We have to ask about such things..."

After listening to Lu Xin's serious question, her mother began to smile and said, "silly child, are we real? Shouldn't we look at you?"

Lu Xin listened to the answer and sat at the table indifferently. For a moment, she didn't know what to do.

My mother chuckled and said, "isn't it true that we live together, accompany and help each other? If family company is not real, what do you think is real? "

Listening to these words, Lu Xin felt a strange emotion.

He thought about his life, it was real.

"Ah, yes..."

Mother seemed to suddenly think of something. She took out a letter from her satchel and handed it to Lu Xin with a smile. She said, "I saw your letter in the mailbox downstairs just now, so I picked it up for you. It was from the orphanage..."

"I didn't peep..."

“……”

"What does she do by mail?"

Lu Xin's face stretched slightly and took the letter.

As she got up and walked to the room, her mother casually replied, "she wants to call you to eat dumplings..."
