Chapter 316 Air Optimization System
"They went to rooms 306 and 307 of that 'Home Inn Hotel', and opened it for three days. It seems that they intend to stay here for five days. There are already people in room 308, so I only give room 305 to the hotel. It's settled." After Zhang Xueqiang came back, he handed a room card in his hand to the big man.

"Do rooms 306 and 307 have windows?" Ding Xiaojun looked at Zhang Xueqiang and asked.

"Yes, yes, by the window, it's on the right side, Xiao Hei, look, it's those two windows." Zhang Xueqiang stretched out his hand, pointing to one side of the wall of the hotel.

Ding Xiaojun looked at the window that Zhang Xueqiang was pointing at, and then at the upward direction of the hotel, his eyes finally stopped at a seven-story building.

"That hotel seems to be able to look at the opposite side. I went to get a room on the opposite side and observed from the opposite side." Ding Xiaojun pointed to the seven-story building and said.

"Very good, I think it's okay, big man, you were the one who passed by room 305, I've appeared in front of them before, and it's not easy for them to be suspicious once I show up." Zhang Xueqiang looked at the big man and said.

"Okay, I see." The big man took out the keys of the motorcycle from his pocket and handed it to Ding Xiaojun: "I left the car at the gate of the police station." The big man said and pointed to the motorcycle in the distance. The gate of the police station.

Ding Xiaojun took the motorcycle key, looked back at the gate of the police station, and nodded to the big man: "Okay, I see."

After the big man left, Ding Xiaojun went to the nearby hotel to observe, while Zhang Xueqiang stayed to observe the movement.

Ten minutes later, Ding Xiaojun walked into a room on the fourth floor of the hotel where he was staying. It was obvious that there were guests in the room not long ago. The smoke in the room was very heavy. It should be that the guests who left had smoked a lot before leaving. .

Ding Xiaojun immediately wanted to change to the next room, so he picked up the phone on the table and dialed to the front desk: "Hello, there is too much smoke in the room I just opened, can you see..."

"Sir, I'm sorry, we will arrange staff to turn on the air optimization system for you immediately, sir, please wait for a while." After the front desk said this, without giving Ding Xiaojun any response, he hung up the phone again.

Ding Xiaojun held the phone in his hand and was stunned for a moment, then hung up the phone and turned his gaze to the direction of the door.

"This hotel looks a bit small, but it's quite advanced. There is also an air optimization system. This air optimization system sounds like a technological product. I'll have to take a closer look." Ding Xiaojun I thought to myself, I am also a technician, if this so-called air optimization system is very easy to use, I can understand the principle thoroughly, maybe I can use its principle in the magazine.

Just as Ding Xiaojun was thinking, there was a knock on the door outside. Ding Xiaojun walked and opened the door of the room. After opening the door, there was a hotel attendant pushing a cleaning cart at the door.

"Is it because you have a lot of smoke here?" The waiter looked at Ding Xiaojun who opened the door and asked.

"Well, yes, your front desk said that there is an air optimization system." Ding Xiaojun looked at the waiter and said very seriously.

The waiter looked at Ding Xiaojun like an idiot, seeing that Ding Xiaojun seemed serious, the waiter pushed Ding Xiaojun away, entered the room from the little space he gave up, and went straight to the window sill.

Ding Xiaojun followed closely behind the waiter. He really wanted to know the principle of this air optimization system and whether it could be used in certain scenes of the army.

The waiter walked to the edge of the window sill, grabbed the curtains and swung them to both sides, and opened the curtains. Ding Xiaojun carefully observed every movement of the waiter, opened the curtains, and the waiter pushed open the glass of another window. And pulled the screen window to the part where the glass window was opened.

The waiter finished it, clapped his hands, and walked outside. Ding Xiaojun stared in disbelief: "Hey, didn't you mean the air optimization system? Have you turned it on?"

The waiter stopped, turned around, and looked at Ding Xiaojun: "Isn't this just that the air has been optimized? With the windows open, the air in the room can circulate. Isn't it just that the dirty air has been optimized? It's such a big deal." , I still have to run.”

Ding Xiaojun was stunned, and there is such an operation, which is too daring to imagine: "This is the air optimization system, I am dizzy, your front desk may be able to talk about such a high-end name. The result is to open the windows to keep the ventilation."

"You don't really think that there is some high-end air optimization system, right? The front desk is a little girl who likes to play tricks. If you really think deeply about her words, then you are really stupid, and there are others Is there any business, I will leave without it, and I still have a lot of things to do?" The waiter looked at Ding Xiaojun half-jokingly.

"No more, nothing else." After Ding Xiaojun finished speaking, the waiter turned around and walked out. Ding Xiaojun went to close the door. Just as he grabbed the doorknob, before closing the door, the waiter stretched out his hand again to block the door. on the door.

"The girl at the front desk said that after the air optimization system, there will be an air freshening system. I almost forgot." After the service finished, she smiled at Ding Xiaojun, and under Ding Xiaojun's puzzled eyes, she walked into the room again Come here.

"I don't need to guess, this is another fake high-end device." Ding Xiaojun said to the service, the waiter turned his head, looked at Ding Xiaojun and smiled.

"You're not stupid." The waiter said, and asked Ding Xiaojun: "What kind of fruit do you like?"

"What fruit do we like?" Ding Xiaojun replied casually to the waiter.

"Choose one, apple, banana, orange, which one is delicious." The waiter looked at Ding Xiaojun and said again.

"Is there any durian?" Ding Xiaojun also asked half-jokingly.

"You really know how to joke, just apple flavor." After the waiter finished speaking, he took out a bottle of air freshener and sprayed it on the sky of the room a few times.

"Okay, the air freshening system is done, now I can go." Taking the service and smiling at Ding Xiaojun, he put away the light air freshener again, opened the door of the room and walked out.

"I'm dizzy, this is really tricky, it really is a routine, the air optimization system, I still want to figure out the principle, try to improve some places that can be used in the army, you are just ventilation, it's still fresh System, spray a few times of air light freshener, it is the air light new system." Ding Xiaojun shook his head, not thinking about this pit anymore.

Ding Xiaojun walked to the edge of the window sill, and looked from the edge of the curtain to the two window sills of the opposite hotel.
