The response from the other end of the phone was no response.
Ren Yi didn't speak either, he waited patiently for Gong Yingxian.
After a long time, Gong Yingxian asked in a very low voice that might disturb someone: "Go ahead."
"Do you remember the protective clothing you wore when you helped me handle the chemical tank truck?"
"Remember."
"The gas mask we wear has a whole piece of glasses like ski goggles or diving goggles. The exhalation port is thick and cylindrical, and there is a large filter box on each cheek."
Gong Yingxian vaguely realized something.
"That's a new type of gas mask. It's not very new either. I already had this type of gas mask when I went to the Armed Police University. But the old-fashioned gas mask doesn't look like that." Ren Yi took a deep breath and continued, "Old-fashioned The mask of my dad’s era, first of all, the place for the glasses is two separate large round mirrors, there is no filter box on the cheeks, the filter element and the exhalation port are integrated, and it becomes a filter. The filter does not have the current exhalation The mouth is so thick, but longer."
"You mean... the bird mask I saw was actually an old-fashioned gas mask." Gong Yingxian's voice trembled a little.
"I think it's possible." Ren Yi said, "First, as I told you last time, I guess the murderer may have worn protective equipment. Second, you were young and it was late at night."
"I wasn't very old at the time, but a six-year-old child shouldn't be able to tell the difference between birds." After Gong Yingxian finished speaking, he began to feel uncertain, but his impression was clearly...
What is it? Except that he was convinced that it was a bird's mask, but what it looked like was just a blurry image in his mind.
"I've been in elementary school since I was six years old, so I already remember things." Ren Yi frowned, "This is just my guess, I saw a spare mask from abroad in class today, and suddenly I felt a bit like the mask worn by Zi Yan , and then thought of... In short, you can use it as a reference."
"I, I don't know." When handling cases, Gong Yingxian has always been decisive and resolute, and rarely lacks confidence in his own judgment. Even during the tens of minutes of racing against time at the concert, any mistake would cause irreversible consequences, and he did not question any of his decisions, and the facts proved that he was all right.
But now he is really confused, because people's memory can be deceiving.
"Let me send you some photos of old-fashioned masks." Ren Yi said softly, "Ying Xian, don't panic, the truth will always come out, and on that day, all their tricks will be exposed."
"Okay." Gong Yingxian said, "This is a very important clue. If it can be confirmed, it will be very helpful to the case."
"Well, there were relatively few shopping channels in that era, especially for such uncommonly used things, maybe something can be traced."
"Ren Yi, have you ever thought about it?" Gong Yingxian hesitated for a moment, "That person may be... a firefighter... or something related." He still didn't say the word "firefighter" in the end.
Ren Yi bit his lips: "... I thought about it. Emotionally, I'm not willing to think in this direction, but intellectually, it's possible."
This case is so complicated, but it is closed so easily and quickly, maybe there is more than one ghost inside.
"Emotionally, I don't want the police to have internal problems, but intellectually, there were problems." Gong Yingxian said sullenly, "I will continue to investigate, you... have you finished your studies?"
Ren Yi felt that Gong Yingxian swallowed back what he really wanted to say, but suddenly changed the subject, so the last question seemed a bit abrupt. He knew that there was no evidence at this time, and it would be useless to say more, so he didn't ask further, and said: "It's over this afternoon, and there is another class in the afternoon."
"I haven't left to look for you these days. I'll pick you up sometime in the afternoon."
"You can do your work, there will be a car to take us back to the squadron in the afternoon."
"I want to pick you up." The last time they went to dinner after a meeting, the incident at the barbecue restaurant happened, and Gong Yingxian was still a little uneasy.
Ren Yi smiled slightly: "See you at half past five."
When I came back from the phone call, I saw that everyone in the classroom had left for dinner, only Yan Jue was still sitting in his seat.
"Why don't you go to lunch?"
"Wait for you."
Ren Yi laughed: "What are you waiting for me?"
"You have been absent-minded throughout the class, and your face is not very good." Yan Jue looked deeply at Ren Yi, "You are now a key protection target, so it is reasonable for me to care."
"It's okay." Ren Yi packed up his things, "Let's go, let's eat."
The two left the classroom side by side, Yan Jue glanced at Ren Yi from time to time.
Ren Yi said helplessly: "It's really all right, the phone call just now helped the case."
"Did you call the palace police officer?"
"Ok."
Yan Jue was silent for a while, and said sullenly, "Is there nothing I can do for you?"
"Who said that you were the one who helped me wrap the pipes at the barbecue restaurant that day."
"I can help you in other places, as long as you ask."
Ren Yi smiled and said, "No problem."
During the meal, colleagues from the Propaganda Department were taking pictures with their cameras.
Someone booed: "What's so good about eating?"
"Take a picture of our food."
The camera gradually came to Ren Yi's side. Yan Jue seemingly casually grabbed Ren Yi's shoulders, and smiled heartily at the camera: "Si Huo, look at the camera."
"Hey, wait for me to swallow this!" Ren Yi stuffed the food into his mouth in a bit of embarrassment, his cheeks swelled like a squirrel, and he choked himself, covering his mouth and coughing.
Yan Jue smiled and followed his back: "Take your time, take your time, why are you in a hurry."
Everyone around is happy.
Ren Yi finally breathed a sigh of relief: "It's not you, you suddenly want to take pictures. This group of people is hurt, they dare to release my ugly pictures."
The person who took the photo giggled and said, "It's true, I recorded this part, what a great material."
"Fuck, cut it off."
"Captain Ren, you have such a heavy burden. Don't worry, for the sake of the good image of our firefighters, I will definitely cut out the dirty words you just said."
Yan Jue took the tissue, wiped the corners of Ren Yi's mouth, then broke his chin, and took a closer look: "Okay, handsome, let's shoot."
The two smiled at the camera, and the camera clicked.
-----
After the last class in the afternoon, the three days of study are over.
Ren Yi went back to his room to pack his luggage and waited for Gong Yingxian to pick him up. At this time, there was a knock on the door of the room.
Open the door and look, it is Yan Jue.
"Come in and sit down."
Yan Jue carried the luggage: "What are you sitting on, I'm going downstairs to take the car."
"Oh, I told the team leader, I don't take the car, someone will pick me up."
Yan Jue was taken aback for a moment: "That palace police officer again?"
"yes."
Yan Jue frowned with thick eyebrows: "He seems very worried about you."
"After all, he has faced those perverts directly, and now the police secretly follow me wherever I go." Ren Yi raised his eyebrows, "It's enough to face."
"You two have such a good relationship." Yan Jue stared at Ren Yi, "The police have already protected you, and he will come to pick you up in person."
Ren Yi didn't know how to answer for a while, so he could only laugh: "We still need to discuss the case."
"Then I'll go first." Yan Jue's complexion was not very good, "If you have nothing to do at night, let's play games together, and you can call me anytime."
"No problem, see you later."
At this moment, Ren Yi's phone also rang. He looked down and saw that it was Gong Yingxian, who seemed to have arrived early, "Hello, are you here? OK, I'll go down now."
After hanging up the phone, Ren Yi took the luggage: "Let's go, let's go down together."
When they went downstairs, the minibus that sent them was parked at the door. Squadron leaders got on the bus one after another, and the black Wrangler was parked behind the minibus.
The windows of the Wrangler suddenly and slowly lowered.
In such a cold day, there is actually no need to open the windows, not to mention that Ren Yi is very familiar with this car.
Gong Yingxian lowered the car window to see the people around Ren Yi clearly. Since they were all wearing the same clothes and they were far away, he couldn't see clearly at first, but when he got closer, he was sure that it was Yan Jue who was talking and laughing with Ren Yi.
Gong Yingxian hummed in displeasure.
Ren Yi waved his hand towards Gong Yingxian and shouted, "Wait a moment."
He shook hands with the squadron leaders to say goodbye, said politely, "Let's have a drink together next time", and then watched them get into the car.
When it was Yan Jue's turn, Ren Yi stretched out his hand and teased, "See you in the Canyon of Kings."
Yan Jue smiled, and when he held Ren Yi's hand, he suddenly pulled him into his arms, hugged him, and patted his back twice: "Goodbye." At the same time, he turned his head, He stared straight at Gong Yingxian in the car, his eyes seemed calm, but there was an elusive emotion in his eyes.
Gong Yingxian narrowed his eyes, and a small flame of anger blazed up—he felt that Yan Jue was provoking him.
Ren Yi was a little surprised, but didn't think too much, and patted Yan Jue on the back: "Let's go."
After the two separated, Yan Jue got into the car, and Ren Yi also got into Gong Yingxian's car. He threw the simple luggage into the back seat, rubbed his hands and said, "It's been a while since I came out of the hotel, and my hands are numb. , it’s really cold today.”
Gong Yingxian pursed her lips, still remembering the way Yan Jue looked at him just now, the more he thought about it, the more unhappy he became, but he felt that maybe he was being superstitious, and normal male friends would hook up with each other.
"Close the window?" Ren Yi looked at Gong Yingxian in confusion.
Gong Yingxian came back to his senses and raised the car window, "Have you eaten yet?"
"No, the canteen here is not delicious at all."
"I'll take you to dinner."
"Go to your house? No, I have to go back to the squadron."
"No, go to... a restaurant."
Ren Yi was surprised.
