Thanks to the monthly pass of the firewood knife eight bars -

Railway!

How could Wu Chen forget such an important scorched earth force.

Chongqing Railway Station is also on the Yuzhong Peninsula. Not far from each other. There is dog meat, which is a matter of 10 minutes.

The square in front of the station is a mountain of car ruins. It's not an exaggerated adjective, but it's literally piled up into a mountain. At the bottom of the ruins are mostly scrapped buses, and on the upper level are the ruins of various small and medium-sized vehicles. And they are supported by rails on the rails.

So, this mountain of ruins piled up with cars is actually a huge bunker. The steel shell of the car is also firmly fixed to the rails, which is extremely strong. The interior space is also very complex and tortuous. Dog meat scanned it casually and found many hidden fire points. These soldiers, sleeping in reinforced carriages, were able to turn the entire ruins into a war hedgehog in a very short time with tongues of fire.

In fact, the steel used for the main structure of the car, especially the front and rear impact beams, is generally very strong steel (this varies from car to car, and there are also foam-filled =.=).

The strength properties of steel, whether 'tensile strength' or 'yield strength', are expressed as stress values in units of 'MPa'. It represents the amount of tensile force experienced per unit cross-sectional area. A stress value of 1 MPa is equivalent to a force of about 0.1 kg per square millimeter.

The higher the MPa value, the higher the strength of the steel body. Generally, the strength of the steel plate is about 100 to 250MPa, and most of the steel used in the vehicle structure of high-end cars is about 1000MPa hot-stamping ultra-high-strength steel plate, and the steel used for front and rear anti-collision beams even reaches 1800MPa. Exceeds the strength of submarine steel.

These were artificially reinforced car batteries. It is the high-strength steel components that have been removed from the luxury cars that are used.

Obviously, these powerful crash-resistant steel beams. Not to defend against fire dragons, but to defend against lizardmen.

It's very simple, if you are poured by the liquid fire of the fire dragon, this mountain of cars that leaks everywhere will burn through from top to bottom. The fate of those who hide inside can be imagined.

Thankfully, the lizardmen don't breathe fire.

Soon, the railroad guards, dressed in homemade steel armor with half tires embedded in their shoulders, armed with machetes sharpened from the car's A-pillars, and shields with modified doors, strode out of the car's bunker. Qi Qi gathered around Wu Chen.

"Is it Lord Sag?" The team actually formed a fairly regular fish scale shield array. And that kind of momentum is obviously not practiced, but cut out with a knife. They've killed quite a few lizardmen.

"I am." Wu Chen opened the cockpit and jumped off the dog's back with his arms.

Everyone breathed a sigh of relief when they saw this iconic black armor, but the formation was not chaotic at all. The sword and shield hand with his back to Wu Chen didn't even look back.

"Our leader is waiting for you, please come with us." The fish scale shield quickly expanded outward, enveloping Wu Chen and dog meat.

"Okay." Wu Chen was also very curious, why didn't these railroad people use guns.

The gate slowly rose, and the team led Wu Chen into the passage supported by the steel rails. Like all remnant sites, they live in the station's underground aisles. The houses renovated by the Green Train are piled up to the ceiling. The junctions of the upper and lower compartments are also nailed together with long rivets. It's very sturdy.

After the fire dragon disappears. The waiting hall has also been reopened and turned into a sizable plantation. It's full of giant mutant fruits. There is a huge fruit tree in the middle. The lush branches were sticking out of the roof. A single tree almost occupies the space of the hall.

It is covered with pineapple-sized fruits, like beautiful lanterns.

If Wu Chen is not mistaken, it is the lantern fruit, also known as Peruvian bitter fruit. In the north, it is called "girl". The fruit is a small, round fruit with a lantern-shaped capsule, a little larger than a thumb, and many small seeds inside. The ripe fruit is bright yellow and very sweet, and can be used to bake fruit cakes, make jams, and eat well as fruit. In supermarkets, it is generally called "pearl fruit".

However, after the mutation, the fruit was already the size of an apple!

After the TT40 scan, it was found that it was too nutritious. Even more than ant eggs.

It felt like a planet that had been burned into charcoal by a fire dragon, desperately releasing the vitality deprived by the flames. As a result, every green plant that emerges from the surface of the ground that has formed a crust will release unimaginable vitality. Whether this is related to the mutant genes or the evolution of the earth itself, no one can say for sure.

Then again, as the whole world is scorched by the dragon, there are only a few remnants of herbs and shrubs left in the horns.

This giant tree full of fruit must be a blessing for the entire remnant site.

Wu Chen found that the way the remnants picked the fruits was also very special. Instead of taking the lantern together, wait for the lantern-shaped capsule to bloom on its own, and then gently pluck the fruit inside. Then, something magical happened. The capsule will automatically close into a lantern shape, and when it opens again, another ripe fruit will emerge inside.

"My lord, you can taste it." Removing a fragrant fruit from a basket of remnants passing by, the leader of the guard carefully handed it to Wu Chen.

"Thank you." The taste is really not ordinarily good. One belly, I feel that my whole body is full of strength.

"Ginseng fruit is nothing more than that." Wu Chen smiled.

"My lord, have you ever eaten ginseng fruit?" A little warrior born in the post-apocalyptic world asked timidly.

"No, it's a metaphor." The lack of civilization cannot be compensated for by a delicious fruit. Fortunately, the little warrior did not ask what a 'metaphor' was.

Walking into the underground passage, which has also been excavated in a large area, a huge smelting equipment stands in the center of the underground hall like a mountain. Wu Chen recognized the steelmaking furnace, the guide rails, and the universal rolling mill. No wonder they don't use firearms! It looks like all the metal is being used by them to roll the rails!

"My lord, the leader is on the rolling mill, and when this furnace is finished, she will come down to meet you."

"Okay." The Chinese 'he' is a homonym, so wait until a female worker slides off a huge universal rolling mill. When he stretched out his hand. Wu Chen hadn't reacted yet.

"Zeng Qian."

"Wu Chen." The female worker generously said her name. Wu Chen hurriedly reached out to hold her calloused hand.

"You're the last Sag?" There is no way, in the Fire Dragon Empire, Wu Chen's identity is equivalent to today's global super popular idol Heavenly King.

"I am. Are you the leader here? ”

"My dad was, and then I followed."

"Understood." Leaders don't have any money to make in this day and age. In addition to endless responsibilities, there are endless obligations. Take the lead in everything big and small, including fighting dragons and lizardmen. Definitely a chore.

Wu Chen looked around at the steel rails piled up in the hall and couldn't help but ask, "What do you want to do?" ”

"Build a railroad."

"Which one?" Wu Chen's eyes lit up.

"You're going to tell us." The female worker said with a smile.

"You don't have a destination?" Wu Chen was stunned. That...... What is cast rail for?

"Ever since the dragon appeared, my father has always had a wish to lead everyone out. So these 23 years. We've been collecting metal from the ruins and bringing it back to cast into rails. ”

"Understood." In fact, in a sense, the railroad people have regarded the casting of steel rails as a kind of ritual. A legacy. Or even a belief. As for whether it can be used, what it is used for, how it is used, and who will use it, it no longer matters. This event has transcended its practical significance. It became a kind of hope and a spark. The railroad people who support the apocalypse, struggle to survive in the ruins of the city where fire dragons hover all the time, and tenaciously continue their mission.

"I heard you're going to lead everyone out." The female worker asked with a calm but bright look, "Is this true?" ”

"Yes." Wu Chen nodded solemnly.

"Okay, we'll follow you." The female worker nodded briskly. But there is a heaviness wrapped in it. But Wu Chen was extremely moved.

It's a life-and-death relationship. Since then, the railroad people have been tied to Wu Chen's chariot.

"I'm going to the Himalayas." Wu Chen said his destination.

The female worker thought for a moment. Quickly picked up an old train ticket from his pocket: T222, Chongqing-Lhasa.

"Will the railroad still work?" Wu Chen thought of the Gold Devouring Ant.

"If it's broken, we can fix it." The female worker said with certainty.

"It's too late." Wu Chen shook his head: "Such a long distance......"

"Follow me." As she spoke, the female worker led Wu Chen to the depths of the hall. The guards then opened a tunnel that had been sealed for a long time. Picking up the helmet and turning on the lights, a strangely shaped train is quietly parked in this post-apocalyptic man-made tunnel.

"T-11A 4-storey long rail train set. It can ship 56 500m long steel rails and lay 14 kilometers of seamless lines at one time. The female leader said with a proud face.

The so-called 'long rail train group' is a special train group for transporting welded railway long rails composed of a variety of special vehicles with different functions and different structures. It is mainly composed of 43 rail cars of 13 models, including camping vehicles, power generation vehicles, safety vehicles, rail vehicles, locking cars, first operation vehicles, operation middle cars, and operation tail cars. Work as you move forward. Wherever the train goes, the tracks are laid.

Wu Chen looked back at the mountains of steel rails again, and could only sigh for the railroad man in his heart.

TT40 had a different opinion: "Master, the nest of the gold-devouring ants is on the south bank of the Yangtze River, maybe the damage to the railway is not serious!" ”

"Take the train to Lhasa?" Wu Chen feels unreliable when he thinks about it!

The female leader led him to a tunnel where war supplies were stored. The vehicle that Wu Chen was looking for for the big lizard that could carry 500 people was quietly parked in the dusty tunnel.

It was a long, double-decker passenger train.

The single carriage is 26.5 meters long and weighs about 20 tons after removing the bulky wheels and various inconsequential auxiliary facilities. Coupled with a 5-ton passenger, there are only a limited number of weapons that can be fitted to rhinoceros iguanas.

Even though there are less than half of the seats, it is still no problem for everyone to squeeze in. (To be continued......)
