Siheyuan starts from a better life

Chapter 767, He Daqing returns to Sijiu City
Everyone received the tasks from Jiang Yan, and after arranging the personnel, under the leadership of Jiang Yan, the design and manufacturing work officially started.

The first thing to do is the overall design of the vehicle. This special protective vehicle needs to be both safe and comfortable in terms of space, so the body size will be relatively large. It is expected to be 6 meters in length, 2 meters in width, and 2 meters in height. The body, doors, windows, and floors are all made of bulletproof materials. , with a thickness of 10 centimeters, it is enough to withstand various light weapons attacks, and even to a certain extent, it can withstand attacks from small-caliber rocket launchers.

In order to better withstand landmines and drive in poor road conditions, the chassis is higher than that of ordinary cars. The tires are bulletproof tires specially developed by Jiang Yan, which can ensure limited driving of the vehicle even if they are punctured.

All the information about this tire has been sent to the leaders by Jiang Yan's secretary, who will coordinate the tire factory for production.

In order to ensure communication security, Jiang Yan also added a high-power walkie-talkie in the car, which can make calls within ten kilometers. This allows people outside to know the situation in the car at any time and increases the probability of rescue.

The engine compartment is also fully reinforced with special materials to prevent direct attack. It is surrounded by special materials, which has a fireproof effect to a certain extent.

In addition to the driver's room, Jiang Yan designed a small place in the car for placing a first aid kit, which can provide certain medical protection in case of injury.

During the design and manufacturing process, Jiang Yan repeatedly emphasized to the technicians the two key points of safety and comfort based on the design drawings.

After Jiang Yan's more detailed explanation allowed everyone to understand the effect Jiang Yan had achieved in manufacturing this car, all departments quickly entered the production preparation stage.

Jiang Yan personally participated in the selection and testing of materials, and selected them in strict accordance with bulletproof standards. For bulletproof materials, he conducted various impact, explosion and other tests until he ensured that its protective performance fully met the standards. For some key parts such as the engine compartment, Jiang Yan also designed modular protective structures to improve maintenance convenience.

"Comrade, thank you for your hard work! This car was finally completed years ago!" Jiang Yan patted Master Wang Sandan on the shoulder and said.

This car requires a large number of relatively precise parts, so Master Wang Sandan was under the greatest pressure. Fortunately, he completed all the work within the specified time.

The workers carefully handled the expensive bulletproof materials and made the car body in strict accordance with the drawing requirements. After repeated testing, the protective capabilities of the car body fully met the design requirements. Small weapons could not penetrate even the slightest. The engine, chassis, etc. were also supervised by Jiang Yan. The production is completed and the running performance is good after testing.

Jiang Yan looked at the black protective vehicle parked in the workshop and couldn't help but smile with relief.

Therefore, they conducted a one-day comprehensive basic test on this protective vehicle. After a day of testing, the overall performance of the car is excellent, especially when carrying such a high load, it still runs at a speed no less than that of an ordinary car.

"Yes, it is not easy to meet the protective performance standards." Jiang Yan nodded, "Installing internal equipment is a test of technology."

The engine, chassis, etc. were also manufactured under Jiang Yan's supervision. After testing, the operating performance was good, and the final acceptance work was quickly passed.

On the twentieth day of the twelfth lunar month, there was a joyful atmosphere in the steel rolling mill.

"But thanks to our group of old disciples, step by step, we finally completed the task!" Master Wang said with a proud smile.

After days of intensive preparations, various productions were finally officially launched. Under Jiang Yan's personal supervision, the production of special protective vehicles was in full swing.

"Haha, it's not hard work. Being able to see this thing makes it worth all the hard work. We finally delivered it before the end of the year!"

"Okay, today we will do the final test to ensure that all indicators are up to standard." Jiang Yan said.

"This car is not easy. We almost stayed up all night several times!"

Of course, true success requires more stringent testing, such as body protection, engine protection, tire protection, etc., which all require special testing at special sites. After passing these tests, the car can Finalize.

Jiang Yan and his research institute obviously do not have such conditions and can only do some basic tests, such as testing the spaciousness and comfort of the car, the operation of various equipment, walkie-talkie communication problems, etc.

After a day of verification, the basic performance of this protective vehicle has indeed fully reached the design specifications, and all performances are excellent. At this time, the senior leader and Minister Zhang who got the news also came to check the results.

"Xiao Jiang, how was the vehicle test?" the two asked expectantly.

"Reporting to the leader, the basic vehicle test was relatively successful and the overall vehicle can meet the prediction. However, if it wants to proceed to the production stage, it needs to undergo more rigorous testing of the system." Jiang Yan said with a smile.

"Okay, okay" I will arrange for professional personnel to conduct testing. Minister Zhang said excitedly.

.

On the 26th of the twelfth lunar month, He Daqing, who had been on the train for a long time, followed the flow of people and walked out of the Sijiucheng Railway Station.

The twenty-eighth day of the twelfth lunar month was He Yuyu's wedding day, so He Daqing returned to Sijiucheng two days in advance to attend He Yuyu's wedding, but no one told anyone about his return.

He Yuyu's wedding was originally scheduled for October 1, but Liu Yi had a very important task at the moment and couldn't coordinate the time, so it was postponed two months.

Although he has often returned to Sijiu City in the past few years, he has never returned to Siheyuan. However, he is still quite familiar with the roads in Siheyuan.

Since today is Saturday, the country has not implemented weekend holidays at this time, so those who have jobs naturally go to work, and the remaining people in the yard are basically women from various families, the elderly and children.

The fine traditions of the third uncle's family have been inherited perfectly by the third aunt. No, at this time, the third aunt is sitting on a small stool at the gate, pasting matchboxes and observing the people coming and going.

It was at this time that He Daqing returned to the courtyard with his things. The third aunt was stunned when she saw He Daqing. She was a little unbelievable and asked tentatively: "Are you... He Daqing?"

He Daqing, who had cerebral palsy, put on a smile that was much better than crying and said, "Haha~ Brothers and sisters, why don't we know each other?"

"My appearance hasn't changed much! It's just that my hair is a little grayer."

Hearing what He Daqing said, the third aunt complained in her heart.

"You can still recognize this paralyzed face in twenty years, don't tell me it's been ten years."

"No, He Daqing, didn't you go to Baocheng? I heard you got married there. Did you come back after a divorce?"

"That's not true." Isn't Yuyu getting married? He Daqing said with a smile: "How can I, a father, not come back?" "

"It's good to come back, it's good to come back." The third aunt nodded.

"What about that, sister-in-law, you just stay busy here. I have to go home and take a look. See you later."

After He Daqing said hello, he stepped directly into the courtyard and walked directly towards his home.

"It's bad. I forgot to tell He Daqing that their family has moved." Not long after He Daqing left, the third aunt who came back to her senses patted her head and spoke.

Just now, she forgot to tell He Daqing about the change of house in their house with Liu Haizhong. It would be great fun if she went in unexpectedly. Thinking of this, the third aunt did not dare to delay and put the things in her hands. He entered the house and ran to the backyard in a hurry.
