"Xiao Li, is it your first time on a business trip?" Master Zheng said with a smile. Master Zheng is over 50 years old this year, he is very kind, and he can usually get along with Li Shan's group of young people, so Li Shan is on a business trip with him, and he can be said to be able to talk to him.

"Yes, it's also the first time to take the high-speed train, you see the display screen shows that the current speed is 198 kilometers per hour, and I don't feel the shaking at all, it's really fast. Li Shan still couldn't hide the excitement on his face.

"Hehe, the nature of our job determines that we will have a lot of opportunities to travel in the future, and slowly you will get used to it. After that, Master Zheng unhurriedly took out a thermos cup from the bag he carried, opened a plastic bag, pinched some tea leaves from it and put it into the thermos cup, and motioned to Li Shan to come a little too, seeing that Li Shan shook his head, he picked up the thermos cup and went to the other end of the carriage to pick up the boiling water.

For Li Shan, who took the high-speed train for the first time, everything felt very fresh. When he pulled the table open, he felt that this kind of thing was really well designed, simple and practical, and did not take up space.

While I was fiddling with it, a person happened to pass by, and a "cut" sound came out of his mouth.

Li Shan glanced at the man, and saw that this person was dressed as a famous brand, and he was full of elite style. At this moment, this person was looking at Li Shan with disdain, and his eyes were full of provocation.

Li Shan recognized at a glance that he had seen this person in the Tianpeng Hotel. At that time, this guy was talking to Han Xin in the lobby, because his arrival interrupted the conversation between them, and the expression on his face at that time made Li Shan remember it deeply.

Obviously, this guy has already recognized Li Shan.

"How did you meet this guy?" Li Shan secretly wondered in his heart.

The two looked at each other for a moment, the elite man snorted coldly, turned his head and continued to walk forward, looking at the direction of the business seat carriage in front.

Shunan Province is located in the southwest of the country, the province has complex landforms, with mountains as the main feature, in the transition zone of the first level of the Qinghai-Tibet Plateau and the second level of the middle and lower reaches of the Yangtze River Plain, the high and low characteristics of the west and the east are particularly obvious, and the test flight base of the Yangtze River Aircraft Industry Group Corporation is located in this basin surrounded by mountains, this company is a large domestic enterprise, is a collection of scientific research, production, testing, A large-scale modern aircraft manufacturing enterprise integrating test flights is an important fighter aircraft development and production base in Huaxia, and this is the destination of Li Shan's trip this time.

After getting off the high-speed train and taking a long-distance bus for nearly two hours, Li Shan and the others finally came to this test flight base with the internal code name 727.

At the gate of the base, Li Shan saw that the armed police soldiers on duty were armed with guns, which made him feel awe-inspired.

Someone needed to guide them to enter the base, and the person in charge of receiving them was a young man in his early twenties, and accompanied by him, Li Shan and the others successfully passed the strict inspection, and only then were they able to enter this very mysterious place in the outside world.

The person in charge of receiving them was a young man in his early twenties, and after completing all the formalities, he pointed to a paper bag that Li Shan had just received and said: "There is a temporary pass with your photo printed on it, and now you can hang it around your neck. Remember, as long as you are in this base, you must hang this certificate, otherwise it will cause unnecessary trouble. ”

Seeing that Li Shan and the others were listening carefully, the young man smiled and continued: "Within the specified time limit, you can enter and exit the specified area with this certificate, and this area is marked on the back of the certificate, and you must be familiar with it." Needless to say, you should understand that you are not allowed to move outside the designated area without permission. Of course, if you need to stay longer after the specified period, you will have to reapply. In addition, there is a more detailed confidentiality requirement in the paper bag, I just said a simplified version, you can learn more about it when you have time. ”

Li Shan listened carefully to his introduction, looked at the area he could enter, and secretly remembered it in his heart.

"My name is He Peitian, I am from the technical department of Changjiang Group, I am responsible for external reception, and I have my office phone number and mobile phone number in your information, if you have any needs, you can find me. ”

"Thank you, Xiao He, I have to trouble you in the future. Master Zheng said very politely.

"Have you been here before?" saw both of them shake their heads. Xiao He continued: "We have beautiful mountains and rivers here, pleasant scenery, and our food here is famous all over the country, since we are here, we have the opportunity to go out for a walk." He Peitian seems to like to make jokes.

"Xiao He, it seems that you have the potential to be a tour guide. Master Zheng said with a smile.

As he spoke, He Peitian led Li Shan and the others to a stop in front of a three-story building.

"This is the No. 5 Guest House, and you live in Room 203, which is reserved for your unit, and the people who came from your Hongqi Factory in the early stage will be in the hangar with everyone else. The canteen is in the red house not far in front, it's twelve o'clock at noon, it's already open, after you have lunch, there will be a car to pick you up and take you to the hangar in the afternoon," and then explained a few more words, He Peitian turned around and left.

According to Xiao He's introduction, every day at 8:15 in the morning and 1:45 at noon, there will be a shuttle bus passing by at the intersection in front, and as long as they show their documents, the shuttle bus will send them directly to their destination.

At noon, Liu Changhui and Yang Rong, who had come to serve here in the early stage, both came back, and they were very happy to see Li Shan. After lunch, they handed over their work, and then Liu Changhui and the two left here.

Li Shan and the others took a short rest in the guest house, and then took the shuttle bus to the hangar in the afternoon to officially start their on-site service work.

There were many people on the car who had documents around their necks like them, and it seemed that they were all people who came to serve on the spot. Since these people were not very familiar with each other, there was no one to talk to, and the car seemed very quiet.

On the way, they encountered another checkpoint, which was more heavily guarded, surrounded by barbed wire, and it seemed that there were some wires wrapped around it, Li Shan couldn't guess what this was about, and along the barbed wire fence at an average interval of about 30 meters, there was a tall pillar erected on it, on which some high-power searchlights were erected, and the armed police soldiers here followed up the difference in the gate of the base, they wore steel helmets and rifles on their backs, their expressions were very serious, and they checked more carefully.

Li Shan had never seen such a battle, and he couldn't help but feel a little nervous. The armed police soldiers carefully checked their identities before they were released. As a result, Li Shan and the others finally entered the core area of this well-known test flight base at home and abroad.

The car pulled them to a stop in front of a hangar, and the driver signaled that they had arrived, and Li Shan and several people followed and got out of the car.

I saw that this hangar was in a very open space, and there was only this one building around, which seemed a little lonely compared to other densely connected hangars.

When I entered the hangar, I saw a very peculiar plane with an earthy yellow exterior painted inside, and the plane was surrounded by all kinds of instruments, and the display lights on the instruments were constantly flashing and making bursts of humming sounds. People are nervously busy, although there are many people but not noisy, the atmosphere is tense but not depressing.

"Can you still do it?" a voice suddenly rang out, and everyone's eyes invariably looked in the direction in which they were speaking.

I saw that it was a soldier in military uniform who spoke, and in front of him a tall expert was explaining something in a low voice, and several other people around him were drooping their heads, looking gray-faced.

"It's still a major general," Li Shan saw a golden flower on the soldier's shoulder.

At this time, the general seemed a little excited, "It's been a few days, and there hasn't been any progress, Mr. Qi, is this kind of engine good?" said the general staring straight at the tall expert.

"Huashan engine has been developed for more than ten years, we have basically mastered the key technology of this engine, and the performance of the engine should be very reliable. We have found the cause of the current problem, through continuous testing, we analyze that it is not the problem of the engine itself, but the inconsistency of the transmission system and the engine power matching, give us some time, and we will be able to solve it in three days. The tall expert said with great certainty.

"Comrades, time waits for no one, and what we lack most now is time!"

"Then give us two more days, no, just one day. The tall expert gritted his teeth and said.

"Then please. After speaking, the general solemnly gave a military salute to the experts.
