The operating room is brightly lit. I squinted for a while before I finally got used to the light, and at a glance I saw my brother obediently sitting on an operating table, looking at me apologetically. Next to him sat a man and a woman, both in white lab coats.

My heart was beating faster - could it be one of the two who knew how to get Mom and Dad back?

My younger brother seemed to see through my thoughts, and after greeting me, he introduced me softly: "This is Dr. Yuan, this is Dr. Lu, they are both attending physicians of the fourth medical team of Xiangyi Hospital. But it's a pity that none of them are the people we are looking for. ”

"I've heard about you. I'm sorry, but my husband should know how to treat your parents, so don't worry too much. The Dr. Lu held out his hand to me and smiled at me in a friendly manner. I could see that her friendliness was genuine, and I could see that she was doing her best to maintain her demeanor. I could feel that she was actually very tired. This made me very fond of her at once. Because I know that being able to do such a person shows that she is a truly educated person.

"Thank you." I smiled back with gratitude and quickly shook her hand.

"Now we are all looking for Dean Lu, who is her husband." Doctor Yuan next to him also spoke, his tone was calm, he glanced at Doctor Lu, and lit a cigarette casually, "Although I have been looking for it all day, I still refuse to give up on this wasted effort." I told you I couldn't find it. ”

Dr. Lu pursed his mouth, and I was also a little unhappy. But she didn't get angry immediately, but directly crossed him and said to his uncle: "Just now I received a text message from my husband again, and the content on it is different, it is 'large intestine, end'." ”

"I'll see." When my uncle heard this, he immediately came to his senses, took Dr. Lu's mobile phone and began to study it.

I'll lean over and take a look. It's really a simple text message, just four words plus a punctuation, signed "Lu Tenghao".

"Lu Tenghao is my husband's name." Dr. Lu explained.

"'The content is different again' means that there were text messages before?" I question.

"Yes, plus this article for a total of three. The first 'duodenum', the second 'small intestine', and the third 'large intestine, the end'. He doesn't reply to anything we send other than these text messages, and he never gets through to his phone calls. Dr. Lu looked at my uncle with a sad face, as if asking for help.

My uncle looked at it with his phone, thought about it for a while, and then said, "The end should mean that this is the last text message he will send us." These seem to be regular, and if they are in the order of the digestive tract, then they will be excreted directly from the body. But the strange thing is that the duodenum is obviously contained in the small intestine......"

I wondered, "But why did he send these organs?" It's like a puzzle, if you can send a text message, why not send it clearly? ”

"Because there's something wrong with him." Dr. Yuan smoked a cigarette and didn't even look at it.

"Maybe he doesn't have time, and his current situation can't be explained clearly in one or two sentences, so he can only use these metaphors instead." The younger brother touched his chin and frowned and analyzed.

"Or maybe he just wants the doctor to know what it means." My uncle was still holding his mobile phone, looking up at something from time to time, "What do you say only doctors know about these three organs?" ”

"Only doctors should know anything about these three organs." My brother and I pouted. I've completely forgotten about these things since I stopped studying biology in college. Although his younger brother is an active high school student, what he hates the most is endorsement, and needless to say, he definitely can't understand these twists and turns.

"Actually, we might as well think like this," Dr. Lu's eyes lit up when he suddenly thought of something, "Why are they all anorectal?" Obviously, there are so many other organs in between. ”

"yes...... Is it peculiar to the intestines? Uncle was still frowning. My brother and I had basically given up, and we started picking and drawing on the walls.

"Huh? Wait a minute. Dr. Lu suddenly stopped us, then pointed to the marks we had cut out on the wall, and said with some hesitation, "...... Could these intestines refer to the picture? ”

"What do you mean?" My uncle also looked at it.

"You see, if you look like a child drawing, could it be a picture of these intestines?" Dr. Lu said with some uncertainty.

"But the duodenum and large intestine are okay, but the shape of the small intestine is really difficult to grasp." Uncle was a little helpless, suddenly thought of something, his eyes lit up, "Hey, wait, you say, could it be the length?" ”

"Length?" Dr. Lu also seemed to think of something, and his expression began to appear happy, "The adult length of the duodenum is 20~25cm, the total length of the small intestine is about 3~5 meters, and the total length of the adult large intestine is about 1.5m. These...... Could it be his coordinates? ”

My uncle immediately took out a map of the hospital and began to measure it.

It was probably less than a quarter of an hour. "Found it." Uncle wiped the sweat from his forehead, and finally showed a joyful smile, "He should be in ...... In the laboratory on the second floor. ”

"Hey, I've already looked for the lab, so you're just blind there." Dr. Yuan took a puff of his cigarette and sneered.

"No, he must be hiding in some corner that is not easy to be discovered, otherwise he wouldn't have gone to such great lengths to send us these text messages." Dr. Lu's expression was firm, "And...... He shouldn't want to be known by some people. The only thing that is certain now is that these people should not be doctors. ”

My brother and I looked at each other, and we seemed to have a big deal in place.

"Don't say so much, let's go. Try your luck when he's not in the capital, lest he move his position again. With a wave of his hand, the uncle took back the map and turned to leave the operating room. We hurriedly picked up our luggage and followed.

There is still a black hole in the hospital, and my uncle occasionally whispers in front of me to remind "There are stairs here, everyone be careful" and "You have to turn a corner here, everyone follow" or something, my brother and I followed behind Dr. Lu hand in hand, and I don't know if Dr. Yuan came with him.

In the dark, I heard my brother whisper to me, "Sister, are you angry with me?" I feel like you don't like to talk to me when you see me. ”

I ignored him and continued to walk cautiously.

He squeezed my hand and whispered to me with some hesitation: "Sister, in fact, I didn't mean to." I just think that if we stay at home like that, it will definitely not work, and I don't want you to be anxious, or you will beat me, I will definitely not fight back, just ignore me. ”

I still ignored him, and I didn't bother to withdraw my hand, looking around with my fingers out of sight, I regretted that I didn't carry the flashlight at home before I went out.

He seemed to be in a hurry, and began to gently pull my hand back: "Sister, don't do this, what do you want me to say, I will definitely do it, I promise you to do it absolutely, don't ignore me......"

Doctor Lu in front heard it and smiled: "Now you know it's wrong, right?" How dangerous it is to run out by yourself, you are still a high school student, do you know how anxious your uncle is when he receives a call from your sister, and he can't wait to leave here and run out to find you. Your sister must be more anxious than your uncle, have you ever imagined how she feels? But young lady, don't be angry, the most important thing is that he is well, if you are angry, you should be sad, and it is good for the family to reunite. Doctor Lu said, paused, and muttered again, "Reunion is good." ”

I know she's thinking of her husband. After thinking about it in silence, I pursed my lips, and finally the boss reluctantly said, "Do you know it's wrong?" Do you know how I felt? Your guarantee is worthless, so I don't want it. If you do something so excessive next time, I will really ignore you. As I spoke, I remembered the feeling of helplessness, panic, and powerlessness at that time, and my eyes ached, and my heart began to hurt again.

My brother seemed to feel it, and hurriedly said to me in a soft voice: "No, no, never." I don't promise, I prove with my actions, really never again. I was wrong, I understand now, don't be sad. Even in the dark, I could imagine his eager pleading expression through his tone.

I smiled and gently squeezed his hand to show that I forgave him. He breathed a sigh of relief and continued to hold me carefully, as if he was afraid that I would fall.

"Here we are." The uncle at the front suddenly spoke, and then there was a "squeak" and the sound of the door being pushed open.

There were no lights on in the lab. We rushed in, each carefully touching the wall to make the direction.

"Husband-husband-" After a while, Dr. Lu seemed to be unable to help it, and called softly.

"He's not here at all, you can't find him." Dr. Yuan said coolly behind us.

"Then what are you doing with you?" I was speechless and rolled my eyes in the dark. I thought he would just stay in the operating room.

"Shhhh ”
