Ye Hanqing and hundreds of other teachers have been in Longkang Town for three days, and after three days of adjustment, they have also recovered from their initial discomfort and began to slowly accept reality.

It's just that they haven't been assigned anything to do in the past few days, there is no shadow of the school, and they don't know when they can officially start classes.

Speaking of which, the climate here is not bad, the climate is mild, surrounded by mountains, and the air between the basins is also very fresh. Diet is not a big problem, a meal of rice is full, and it is not enough to add it to yourself after eating. In a group of five, a small wooden box is assigned as a dining table, and the vegetables are harvested from the field, such as water spinach, lettuce, celery, etc., as well as some unknown wild vegetables picked from the mountains, and occasionally a fried river fish. There is also a pot of mushroom soup.

Most of these things were grown by the soldiers themselves, fished from the river, and picked from the mountains, and they were fresh and had a good taste. And there is enough oil and water in the dish, and everyone is willing to put away chopsticks only when they have a round belly.

Their previous life in China was not good, farming and harvesting for themselves. Because the farm work is not up to par, there is not much left after paying the public grain, and life is even more difficult than that of ordinary peasant households, and there is basically no time to eat.

Now that there is a full meal to eat, there are fresh vegetables with plenty of oil and water, except for the lack of meat, every teacher is very happy, and I feel like a fairy in this life. If it weren't for the harsh conditions here, the lack of recreational facilities, and the extreme lack of spiritual life, and then thinking about their relatives at home, many people would really have the idea of staying and not leaving.

After breakfast this morning, Teacher Xie pulled Ye Hanqing and Teacher Han in the same room, and went to the hilly area in the east and south excitedly, saying that he was going to take a walk and eat.

To the west is a towering mountain, and the rock walls are too steep to climb. The west side is too far away from the residence, and the gentle slope on the east side was opened up by the troops as a vegetable garden, and dozens of acres of vegetable land are planted with green lettuce, celery, green onions, ginger, garlic and other crops.

They have worked in the countryside for several years, and they have long tasted the hardships of farm work. No matter how good the vegetables are and how beautiful the scenery is, they don't want to get close, and if they unintentionally sweep their eyes, they will immediately turn away, and they don't want to take another look.

"The scenery here is so beautiful...... the group slowly marched towards the hills, seeing all kinds of strange wildflowers swaying in the wind, bursts of floral fragrance drifting with the wind, inhaling the end of the nose, bringing a refreshing fragrance, the three of them all felt extra comfortable and relaxed.

How long has it been since I felt like this!

Ye Hanqing looked at the large-leaved banana trees growing halfway up the hills, and looked at the morning mist that had not completely dissipated, and was full of emotion.

"Huh? Isn't that Captain Meng, what are they going to do in an uninhabited valley early in the morning? Teacher Han had good eyes, and suddenly pointed to a liberation truck in the distance and said.

Ye Hanqing and Teacher Xie looked in the direction he pointed, and saw Captain Meng and several members of the field engineering team sitting in a liberation truck, driving towards a small valley surrounded by a small mountain.

The car was also loaded with bricks, cement and other building materials.

There are many hills in the south, there are many small valleys, the valley they went to is very small, about ten meters deep, the entrance is narrow, the inside is wide, I don't know where Captain Meng is going and what they are doing.

"Let's go, let's take a look!" Teacher Xie was the most energetic and encouraged.

How did they get to a strange place, although the 291 Brigade is composed of educated youth, they always feel that they are outsiders. Internally, they still prefer to be close to people who have come from China together. Seeing what Meng Nan seemed to be doing, he couldn't help but be curious and wanted to go over and take a look.

"What will we do later?" Teacher Han was a little timid and hesitated.

"What will happen? There are no school buildings here, so I don't know when or when it will be repaired. It's our turn to teach, and it's the Year of the Monkey. You see, no one cares about us these days, what's the point of not walking around and sitting in the house? Teacher Xie said.

Ye Hanqing was also a little moved, they came in a hurry, except for some daily necessities, they didn't bring much other things. Some teachers also brought a book or two with them, which they could turn over and over to pass the time, but they didn't have to read any books, and they were really bored sitting in the room all day.

"Then take a look?" He looked at Teacher Han.

The three of them didn't care about the wild flowers under their feet, climbed over a few hills, and climbed to the small valley and mountain where Captain Meng and they entered.

From here, Meng Nan and the others seemed to be planning to repair something here, and several people stood next to the truck, pointing against a construction drawing, and then pointing to a vacant lot next to the hill.

An engineer opened the rear compartment, took out a roll of twine from it, and formed a circle in the clearing.

Several other workers took out a few shovels from the car and began to level the land.

"Let's go, let's go down." Ye Hanqing was also curious, said something, and ran down the hillside first.

Meng Nan and the others heard the voice, raised their heads, saw that it was them, and continued their work.

The place they chose was quite fair, and when Ye Hanqing and the three of them came over, they had roughly leveled the land, drew lines with white ash, and looked like they were ready to officially start construction.

"Captain Meng, what are you cultivating here?" Teacher Xie panted and leaned over to Meng Nan, wanting to see the construction drawing from him.

"A generator room will be built here, and a substation and distribution room will be built next to it." Meng Nan folded the construction drawing in half a few times and put it in his arms, not letting Mr. Xie see it.

Because he's embarrassed.

This construction drawing was also provided by Guan Fei. The style, size, and specifications are clearly marked, and they can just follow the drawings for construction. The first field construction team of the Provincial Construction Bureau did some mason work, and he felt that his face was very dull, so he simply did not let these teachers see the construction drawings, lest they see some clues.

The diesel generator set had been shipped back for several days, and Guan Fei was desperate to get it into service. With electricity, a lot of work can be carried out quickly, so when I came back last night, I explained to him and asked him to come early in the morning to build the power generation room and the substation and distribution room.

"Electrified here?" Ye Hanqing and others were overjoyed.

People who have not experienced the civilization of electricity cannot understand how strong their desire for light is. The last thing they can bear when they stay in the countryside is that there is no electricity. When it gets dark, they can't do anything, they sit in the house in a daze. There were no oil lamps for them, and they couldn't read books, write something, or play poker with the flickering light!

Hearing that Meng Nan and the others were going to electrify this closed place, they were so excited that they danced with their hands, and the whole person seemed to be about to fly.

Now that they knew that the engineering team was going to electrify them, it was even more unlikely that they would leave. After the three of them were busy, they took the initiative to help them hand bricks and towels, and they were very attentive, looking at a simple brick house, which was taking shape little by little.

They didn't expect to build a house so quickly.

In fact, this is a small project, but it is two bungalows, and even the foundation is not needed, it can be built directly, and it will be built very quickly.

The generator room is a rectangular building, with a construction area of only 30 square meters, three meters apart in the middle, and two diesel generator sets are placed. The generator house was built in this secluded place, mainly for sound insulation, so as not to make too much noise and affect the rest of the soldiers and townspeople.

These two diesel generator sets are used as a standing power supply, and ventilation needs to be paid especially attention to continuous work. In the front and rear of the two units, a louvered vent was opened, and according to Guan Fei's requirements, an electric fan brought back was installed to speed up air circulation.

The field diesel generator set has its own voltage stabilization system, which can be directly connected to the transmission line, but considering that the diesel generator belongs to the stroke work, the attack value has peak threshold and low peak threshold, and the fluctuation is relatively large. At the request of Guan Fei, a substation and distribution room was specially set up for it, which was connected to the power grid through rectifiers, inverters, and static switchgear.

As for Guan Fei's request to be completed and put into use as soon as possible, this is not a problem.

Meng Nan has long-term experience in field construction, and specially brought a batch of fast-drying cement, which achieved initial setting in 14 minutes and dried thoroughly in an hour. Over time, the strength gradually increases, reaching the maximum design strength after 24 hours. This kind of cement belongs to special cement, they are usually used to deal with tunnel cracks, pipeline repair, more than ten times more expensive than ordinary cement.

A generator room that does not need a foundation and does not consider earthquake proof, and uses fast-drying cement, is really wasteful.

However, Guan Fei is willing to pay more, and he can't help it.

It took them only two hours to completely build the two small bungalows, and then the group left the small valley and returned to the warehouse. The trailer that originally transported the construction machinery left after it arrived, and the goods were placed in the wooden warehouse.

Meng Nan picked at his head, but decided to use a crane to assemble the generator on the car.

The 30-kilowatt generator has a group leader of 2.2 meters, a height of 0.8 meters, a width of 1.3 meters, and a weight of 860 kilograms. This unit is relatively light, and a few more lads can load it into the car.

However, the 80-kilowatt unit is heavy, and the length, width and height are all standard sizes, which are the same as 30 kilowatts, but the total weight reaches 1.6 tons. Manpower can be lifted and loaded into the car, but this is too hard, you can only use levers, ropes, little by little to move to the car, there must be someone in the middle at all times, don't think about it for half an hour.

If you have a crane, why bother yourself.

One of the team members went into the storeroom, checked the fuel tank, then jumped into the car, sat in the cab on the height, and quickly started the crane.

There is a crane, and the 1.6-ton generator set can also be easily hoisted onto the car.

Then two trucks carrying diesel generator sets, together with cranes, came to the small valley again. In less than half an hour, the cement on the outside of the two small houses that had just been built had dried out.

In order to ensure stable operation, the generator set also needs to be fixed with cement.

Meng Nan has long been familiar with all this, and the pit has been dug in advance. A few people did it, hoisted it and got off the car, put it in, adjusted the level, modulated the cement, and sealed the base.

It takes more than an hour to get it done.

After the substation and distribution room, it is simpler, all kinds of equipment are done, and the supporting box manufacturers have also provided, just install it directly.

By one o'clock in the afternoon, all the work was done.

They are all people who are used to doing field work, and Meng Nan and they didn't eat lunch, so they directly began to bury the telephone pole and pull the wire. On average, a telephone pole of 50 meters was used to pull it to another small valley with only four poles.

The rest of the engineering team is also here, and they have arranged some carpentry equipment, lighting equipment, plug-in boards, etc., according to the plan. Wait until the wires come over, and then plug in the electricity.

They had been busy all morning, and Guan Fei had just returned from the army.

"Picked up? Thank you for your hard work, the generator set has been installed, and all kinds of woodworking tools we have left in the warehouse are finally usable! Woodworking machinery and tools can be used, and the construction below has entered the fast lane! Guan Fei shook everyone's hands one by one and thanked them one by one.

"It's nothing, it's not complicated." Meng Nan smiled, "Why don't you try?" ”

"Okay, let's try it!" Guan Fei followed Meng Nan with great interest, took out a barrel of diesel fuel from the warehouse, drove to the generator room, looked at the open environment here, and decided to transfer two people over later.

The power facilities belong to the highest-grade modern equipment of the 291 Brigade, and they are more related to the future development, so he cannot be cautious.

Meng Nan and others are very familiar with these two sets of diesel generator sets, and they have dealt with a lot of units of the same type, filling diesel, checking parameters, and operating control systems, they are very skilled.

In this era, most of the domestic diesel generator sets were started manually, just like tractors, and the crankshaft should be driven to rotate by the handle. Meng Nan waited until his subordinates completed the pre-start inspection of the equipment, stepped forward to open the pressure reducing valve, reduce the air pressure in the cylinder, and then held the handle with both hands, took a breath, and turned the handle violently.

At first, it was more difficult to turn, but slowly the speed came up, and the power consumed was not so great, and the speed of the handle began to increase rapidly.

When the rev reached a certain speed, he quickly removed the handle.

Driven by inertia, the flywheel still drives the crankshaft to move rapidly, the air pressure in the cylinder increases rapidly, and the temperature rises rapidly. When the temperature in the cylinder reaches the critical point, the diesel engine makes a roar and the ignition is successful!

There was a sudden explosion in the cylinder, and the deflagrated diesel fuel pushed the crankshaft piston, reciprocating at high speed in the cylinder.

At the same time, driven by the diesel engine, the generator began to run.

The pointer on the meter jumps up quickly, indicating that the generator is working normally and outgoing current.

When Guan Fei closed the electric switch at the signal of Meng Nan, the light bulb hanging on the top of the generator room burst into light.

Guan Fei looked at the light bulb above his head, which was only twenty-five watts, and his heart was excited.

He has waited for so many years, and he has been looking forward to this day since the moment he joined the People's Army. But at this moment, looking at this light bulb glowing with yellow light, his heart was still fluctuating, and it was difficult to calm down.

Although the wattage of this lamp is not high, it symbolizes that his 291 Brigade has officially left the agricultural era of relying on oil lamps and candles for lighting and completely manual operation, and has entered the threshold of the electricity era!

With the arrival of electricity as a symbol, it symbolizes the future development of the 291 Brigade and opens a new chapter!
