Apocalypse Rebirth: 3000 million won at the beginning

Chapter 2206 Extreme Construction
The railway tracks were shrouded in torrential rain.

The rain poured down on the ground, and the raindrops hit the rails, creating tiny water droplets.

Duan Lin squatted on the ground, carefully examining the degree of bending and deformation of the steel rails on the track.

He took out professional measuring tools and carefully checked the railway tracks within a range of tens of meters. As he moved, Duan Hong and the others quickly followed to protect him, in order to prevent any zombies from getting close and harming him.

Ten minutes later.

After he finished his inspection, a hint of joy appeared on his face.

But when he returned to the bent and deformed section of the rails, his face immediately darkened.

The roadbed in this area was slightly collapsed and deformed, and it was lower than the surrounding roadbed. Due to the rain, the two meters of roadbed were filled with rainwater.

At that moment, they had almost wiped out all the zombies in the area, and the threat posed by the zombies was temporarily eliminated.

However, because the gunfire was so loud, they didn't know if there were any zombies around. Once the zombies heard the commotion, they would definitely come over.

So they weren't really safe, because zombies could approach at any moment.

Once it was temporarily safe, Xie Fei jumped off the roof of the car.

"Old Duan, how bad is the damage? How long will it take to repair?"

He was very anxious. The rain-inducing shells launched from the outpost could only last for a few hours. Once the sea fog returned, they would lose sight again.

Even worse, the DS-1 train will arrive here in two and a half hours.

They had to fix the rail problem within two and a half hours, otherwise...
The train could only stop on the tracks by applying emergency brakes.

When a train brakes suddenly, the intense braking friction can cause wheel tread abrasions, brake disc overheating, affect the performance of the braking system, shorten equipment life, and even cause mechanical failure.

Furthermore, a train parked on the tracks for several kilometers would attract a large number of zombies, and the safety of the passengers and supplies on board could not be guaranteed.

Therefore, they had to resolve the rail issue within two and a half hours.

Duan Lin raised his head and answered:

"The severely deformed area is two meters long, and the slightly deformed area is four meters long. The slightly deformed area can be ignored for the time being. Only the severely bent section needs to be treated."

It should be done in about two hours!

As Duan Lin said these words, his admiration for Shan Zimo, who was far away at the headquarters, grew even stronger.

He could deduce the general situation from just his own description and provide the most efficient and useful solutions.

"Okay, if you can get it done in two hours, that's great. You guys focus on repairing the rails, leave the zombie problem to us!" Xie Fei felt relieved after hearing this good news.

Duan Lin nodded and turned around to see that Zhang Zihao and the others had already unloaded the repair equipment and materials from the vehicle.

He quickly assigned tasks:
"Zihao, the four of you dig up the roadbed in this area."

"Xiaodong, you two dig a drainage ditch between these two locations. The roadbed will need to be refilled with stones later; with this heavy rain, we can't let the water stay in place."

"Okay, understood!"

"okay!"

The group quickly got to work, carrying out the tasks as Duan Lin had instructed.

Seeing that there weren't many zombies around, Duan Lin ran to Xie Fei's side.

"Stationmaster, to prevent more zombies from climbing up here, we must intercept them at the bend. When we leave, we'll use the remaining sand and gravel to block the path leading from the straight road to the tracks!"

"Although there will definitely still be zombies crawling out of the bushes, there certainly won't be as many as before!"

"In addition, we brought a few extra steel posts to nail down that path. If you have time, please have someone nail down some steel posts. Sand and gravel combined with steel posts will make it even safer."

After listening to Duan Lin's request, Xie Fei frowned and looked around to count the number of people.

They came with sixteen people this time.

Seven of them were maintenance technicians, and including his own nine combat personnel, Zhou Tan was injured by the Vajra Zombie earlier, leaving only eight combat personnel.

Inside the vehicle, Zhao You and Huang Ming are operating machine guns and heavy machine guns to guard against a large number of zombies approaching.

The remaining Zhao Bing and Duan Hong were responsible for the zombies at the front of the track, while Xiao Huangniu and Lao Fengzi were responsible for guarding the zombies coming from the back of the track.

He Le was specifically responsible for protecting their construction safety, while he himself needed to stand on the vehicle to oversee the entire situation, direct everyone's actions, and act as an observer.

After a moment's thought, he used a communicator to contact Zhao You inside the armored combat vehicle: "Xiao Zhao, come out."

Zhao You, who was in charge of the heavy machine gun inside the vehicle, crawled out.

"Station manager, you wanted to see me?"

"You and Zhao Bing, listen to Lao Duan's instructions and nail those steel pillars to that path, do as he says."

"Yes."

Zhao Bing, who was in charge of the front section of the track, also ran over.

There shouldn't be too many zombies in the first section of the track, but the probability of encountering zombies is higher in the second section.

Therefore, Xie Fei transferred Zhao Bing from the front line to help.

After explaining everything, Xie Fei climbed onto the roof of the vehicle and used the infrared thermal imaging on his tactical helmet to observe the surrounding activity.

Led by Duan Lin, Zhao Bing and the other person hurriedly ran to the repair vehicle and carried the steel pillars down.

Time passed by, second by second.

Everyone was in a hurry, so Zhang Zihao led three maintenance workers to dig the foundation as quickly as possible using shovels.

Along the way, they took off their tactical helmets to make it easier to work.

This tactical helmet was produced by the Dazhangshu Military Factory and was modified and upgraded from a previously collected tactical helmet.

It is equipped with red thermal imaging, night vision, headlamps for both near and far distances, and strong impact resistance.

However, it has only one drawback: it is too bulky and uses a fully enclosed design.

Wearing this helmet makes it somewhat inconvenient to do physical labor.

Huhu——

Zhang Zihao rubbed his hands together; the perceived temperature was now almost zero degrees Celsius.

Every breath they exhaled was a white mist.

bang~
Every now and then a few zombies would appear, but Xie Fei, standing on the roof of the car, spotted them and shot them accurately.

He doesn't know how to repair things, but he's quite capable in combat.

Back in the combat unit, his marksmanship was among the best in the entire unit.

In addition, he has organizational and leadership skills, which is why he was assigned to this post as the station chief.

Twenty minutes later.

Zhang Zihao excitedly shouted to Duan Lin:

"Old Duan, is this about right?"

Duan Lin ran over from where the irrigation ditch was being dug, saw only a 50-centimeter-deep pit, and frowned, saying:
"No, it needs to be at least 60 centimeters. It will be even less stable when working in the rain. 70 centimeters would be best."

As he spoke, he called Xiaodong, who was still digging the irrigation canal over there.

"Xiaodong, you can let Lao Xing dig over there. He's almost done it. Let's dig the roadbed together."

Subsequently, with the addition of Duan Lin and Xiao Dong, the six of them worked together to dig the roadbed with shovels, which increased their speed by half.

Fifteen minutes later.

They dug a pit that was two meters long, one meter wide, and seventy centimeters deep.

Simultaneously, during this process, Duan Lin erected a temporary rain shelter above the pit.

To prevent rainwater from falling into the pit and causing instability in the roadbed.

"Put the big stones at the bottom to fill the gaps," Duan Lin shouted.

dong dong dong~
Zhang Zihao and the others pushed the large rock down, then jumped into the pit to adjust its position, trying to keep it as flat as possible.

Then they compacted the roadbed with gravel.

"Pour the concrete quickly!" Duan Lin said to Zhang Zihao.

Zhang Zihao quickly ran to the repair truck and drove it over. There was a small mixer on the truck.

Kangchi Kangchi~
After the mixer thoroughly mixes the quick-pour high-strength concrete, it is quickly poured into the pit through the pipe.

In less than ten minutes, the concrete filled the entire pit.

"What do we do next?" Zhang Zihao asked.

Duan Lin looked at the rails on both sides and said, "First, check and secure the rails except for this section. Also, take down the tarpaulin from the car and get ready."

"Yes!"

Zhang Zihao brought someone into the car to get something.

Duan Lin looked at the quick-cast concrete on the surface with a worried expression. Although this type of concrete sets quickly, the temperature is low now, and it's raining, so the quick-cast concrete won't set as fast.

"Stationmaster, how much time do we have left?" Duan Lin asked Xie Fei in the car.

“An hour and a half,” Xie Fei replied.

Duan Lin squatted down and touched the surface of the concrete; it was still wet.

At this rate, it will take at least half an hour to initially solidify and an hour to harden.

There's not enough time.

On a hot, dry day, this time can be reduced by three times. It can be completed within thirty minutes.

But the environment is different now.

What should I do?!
He rushed to Xie Fei's side and shouted:

"Stationmaster, the quick-poured concrete is setting too slowly. At the current rate, I estimate it will take another hour and a half to harden!"

Xie Fei felt completely overwhelmed after hearing this news.

"What the hell!"

"Didn't you say it would only take half an hour at most to harden? How come it now takes an hour and a half? Are you kidding me?"

Xie Fei was completely stunned.

Duan Lin replied awkwardly:

"We hadn't considered this kind of torrential rain and cold weather before. If it were during the previous drought and high temperature, there wouldn't have been any problem at all."

"Grass."

Xie Fei's brain went blank for two seconds, but he quickly recovered.

Reason told him that getting angry was useless; the important thing was how to solve the problem at hand.

"How can we speed up the setting and hardening of concrete?"

Duan Lin thought for a moment and replied:

"One is temperature, and the other is humidity. If the temperature is relatively high and the humidity is relatively low, it should..."

As they spoke, he and Xie Fei simultaneously came up with a plan, and they said in unison:

"Start a fire!"

Xie Fei quickly said:
"Making fires around here should solve this problem, right?"

“But,” Duan Lin looked at the surrounding bushes and grass, “these plants are all wet and won’t burn.”

Xie Fei pointed to the repair vehicle across the street and said:

"That repair truck uses gasoline, which is flammable. Just extract some gasoline and burn it."

"That's right!" Duan Lin slapped his thigh and excitedly shouted to Zhang Zihao:
"Zihao, hurry up and get some wood and dry grass to burn!"

Xie Fei quickly called He Le to go and protect them.

In addition, Zhao Bing and Zhao You had already installed the steel pillars, and Xie Fei had called them over to help.

soon.

Next to the quick-poured concrete was a pile of wet wood and weeds.

However, these pieces of wood and weeds are kept about half a meter away from the poured concrete, and are not directly close to the concrete.

the other side.

Duan Lin used a straw, inserted it into the fuel tank of the repair car, and took a big gulp, using the siphon effect to draw out the gasoline from the tank.

Wow~
Gasoline spilled onto the wood and weeds.

When the watering was almost finished, Duan Lin pulled the hose out.

Click~
He lit the gasoline with a lighter.

rub!
The gasoline ignited immediately, and the fire quickly spread, engulfing the central concrete structure.

Unexpectedly.

Upon seeing the size of the flames, Duan Lin not only did not feel happy, but instead looked anxious.

"Quickly, control the fire. Never let the flames come into direct contact with the concrete. You must ensure that the fire burns as evenly as possible within a certain area."

"Also, clean up all the rainwater around here. Don't let it flow into the concrete."

He was in such a hurry because the direct burning of the flame would damage the structure of the cement hydration products in the concrete, causing the concrete to harden prematurely but ultimately reduce its strength significantly.

The surface may peel, crack, and powder, which seriously affects its load-bearing capacity.

They had just used an early-strength agent, but its effectiveness is limited in this environment.

That's why the idea of ​​using uniform combustion to accelerate concrete setting came about.

Upon hearing Duan Lin's words, Zhang Zihao and the others quickly used sticks to push away the burning wood.

cough cough~
The damp wood, burning fiercely, emitted thick, pungent smoke.

They quickly put on their tactical helmets, which made them feel much better.

Wow~
The tarpaulins above their heads catch the rainwater falling from the sky. Once the rainwater accumulates to a certain amount, it flows down along the edges of the tarpaulins.

The people who dug the ditches have also returned.

The steel piles and rails at both ends have been fixed in place; only this section of rail is missing.

Time passed slowly.

Twenty minutes later.

Duan Lin jumped into the fire pit and reached out to touch the surface of the concrete to check its hardening.

Okay.

It has already solidified, but its hardening strength is not yet sufficient.

He carefully observed the condition of the concrete surface and found no cracks, indicating that this method of evenly burning the concrete over a half-meter distance did not cause much damage to the concrete's setting.

"How much longer?" Duan Lin shouted at Xie Fei.

"An hour? How much longer do you want to go?" Xie Fei retorted.

Duan Lin replied:
"Forty minutes."

"Okay." Xie Fei nodded, and didn't exceed the time limit.

"Zhao You, go inside the train and contact Train Conductor Xiao to ask where they are."

"Yes."

Another twenty minutes passed.

With Duan Lin's precise control of the fire, the concrete finally reached his expected strength after burning for forty minutes.

"Put out the fire! Start securing the rails and posts! Quickly!"

The group went over together, removed the still-burning wood, and casually tossed it into the nearby bushes.

The ground, which had been burned by the flames, was still hot.

But they had no time to worry about that; they quickly took action to reinforce the rails and steel piles.

Another twenty minutes passed.

The deformed rail has been repaired.

Duan Lin stepped on it to feel it, and then used professional equipment to test it.

"That's about enough. Hurry up and fill the remaining sand and gravel into that path!" Duan Lin shouted to Xie Fei.

But Xie Fei stood motionless. "Station Chief?"

Xie Fei stared at the valley to the south, where the infrared thermal image showed a dense cluster of red dots.

The high-end infrared thermal imaging they use can observe distant objects.

If it weren't for the mountains and forests blocking his view on both sides, he could see the thermal imaging situation thousands of meters away.

In heavy rain, infrared thermal imaging is suitable for observing situations ten meters or even tens of meters away.

At close range, it's clearer to see with the naked eye.

He shuddered, then suddenly turned around and shouted at everyone present:

"Get in the car! Get in the car! A large number of zombies are coming from the southern straight road! Hurry, hurry, hurry!"

Upon hearing this, everyone's expression changed drastically.

They quickly picked up the equipment and tools from the ground and ran to the car.
