Armored train in the apocalypse

Chapter 98 Damage and Repair

Immediately afterwards, Yu Jing handed over the object that was about one meter square.

"This is a new material I developed to replace the existing tempered glass. It incorporates gelatinous substances extracted from the butcher's body, the skullcrusher's hammer, and special fibers that Wan Xing collected from a plant..."

Su Huan was greatly surprised. In his previous life, he had little contact with the creators and collectors, and only knew that they were two magical realms.

But I never expected it to be so amazing.

"I can roughly understand adding gelatin, but what's the story behind the skull crusher's hammer?"

"The Skull Crusher's hammer has a unique structure; it is a hollow, special shape that appears large but is actually very light. It only becomes hard when it is filled with blood during combat."

Su Huan chuckled, "It can even change in intensity? I thought it would always be the same."

"Perhaps by utilizing this structure, these materials fused together under my erosion, forming this special piece of glass."

Su Huan took the glass and transferred some energy to the light above his head, making the corridor brighter.

Then he looked down to examine the "glass".

Under the light, you can see that the inside of the glass has a hexahedral shape, with the pieces arranged in an orderly manner, giving it a sense of aesthetic order.

It disappeared again after tilting slightly.

Yu Jing explained from the side, "I have already tested the glass. Its hardness is similar to that of stainless steel, but its toughness far exceeds that of steel. Even if it is subjected to an unbearable attack, it will only show damage like a plastic film, instead of shattering completely. Most importantly, it can withstand a temperature of 1200 degrees Celsius and will not melt like the previous piece."

Seeing that Su Huan didn't speak, Yu Jing assumed he hadn't understood, so she used a simpler explanation: "In other words, he is actually a soft material."

Su Huan pondered for a moment, then asked sincerely, "About how hard is stainless steel?"

"...It's a common high-hardness metal, usually used in high-end cutting tools and bearing balls."

Can it stop bullets?

"If it's stainless steel, it might not work. Stainless steel has too little toughness. The new material has high toughness, so I'm not sure. Testing would require more precise equipment."

"No need for all that trouble, it can be tested in ten minutes."

Su Huan quickly called Xiao Ba over and had Liang Kuan and the others move some guns and ammunition to carriage number 10.

Xiaoba manipulates the metal to secure the new glass to the carriage.

Su Huan tried out all sorts of guns.

After a thoroughly enjoyable wilderness test, Su Huan accurately determined the limits of this glass.

It can easily deflect regular pistol bullets, barely deflect 5.56 rifle bullets, and won't work if multiple shots hit the same spot. It can just penetrate 7.62 regular bullets, leaving a stretchy, gel-like tear.

Another piece of good news is that armor-piercing bullets are not much different from ordinary bullets when facing this kind of glass.

Clearly, the properties of this material are very effective against armor-piercing projectiles.

"Is this type of glass produced in large quantities? How much can be made in a day?"

"I've finalized the material ratio, but it will take a lot of time to replicate it. The two manufacturers in the crew can produce four pieces a day, even if there are enough materials."

Su Huan narrowed his eyes. It seemed he needed to significantly increase the proportion of evolved humans. Otherwise, with this efficiency, the enemy would have already attacked before his train was even fully armed.

"Are there any difficulties with the materials? I remember you just mentioned a certain plant?"

"Yes, it was brought back from the car body. Wan Xing saw it and tried to collect it. She obtained some tough fibers, which are the lines that outline multifaceted crystals inside the glass."

"Bring it to me and see."

Soon Wan Xing arrived with the mutated plant. Su Huan glanced at it and felt relieved.

He casually explained, "This is wiregrass, also known as tripping grass. Apart from being sturdy and plentiful, it's not dangerous. Because it's extremely resistant to corrosion, it grows everywhere in acid rain areas and can be easily collected."

Yu Jing nodded. "Then I'll have them work at full capacity and see if there are any ways to increase production."

"That's it, let's try to replace all the windows on the carriages with these."

After confirming the new materials, Su Huan listened to reports from various departments and inspected the damage to some trains.

The vehicle body has been corroded to some extent, but it takes at least a few years for corrosion to penetrate a 3mm steel plate, so there's no need to worry for now.

Because the power outage was handled decisively, the vehicle's electrical system itself was not damaged. However, some sockets were soaked by acid rain and need to be inspected before they can be used.

Liang Kuan even went out to take a look. The front of the car wasn't badly damaged, but the welded corner and the shovel head were corroded and looked a bit unsightly.

The brake lever system was corroded, and in addition to the previous collision, it was also damaged and deformed.

There were cracks in the bogie and deformation in the wheel rims, but these metal-related problems were not a big deal.

Xiao Ba had already been dealt with while Su Huan and He Jie were talking.

Furthermore, a significant amount of miscellaneous items and electronic components in carriage number 8 were soaked by acid rain.

These all need to be compiled as soon as possible.

……

At eight o'clock in the morning, after a quick breakfast, the train started again in the acid rain, heading towards the repair shops, steel mills, furniture stores, and material factories around Yijin.

We've been running around non-stop lately, and we're even running out of metal materials.

Washed clean of blood and grime by acid rain, the post-apocalyptic, iron-blooded train dons a rusty, wasteland-inspired paint job as it roams the rain-soaked city.

The people in the carriage were not idle either; they took advantage of their spare time to begin a new round of interior renovations.

First, the steel from the previous scrap vehicle recycling project was used to solve the workers' bed problem, so that everyone could have a bed to sleep in. Although it was a bit crowded with three bunks, at least they didn't have to sleep on the floor anymore.

Then came the interior partitioning and modification of the carriages.

1号车厢和2号餐车之间设立一道闸门，同样的还有5号和6号，6号和7号，10号和11号，11和15之间，根据不同的功能区进行分隔。

The gate is made of first-order lightweight steel previously developed by Yu Jing.

Because of its difficult-to-control nature, it consumed a lot of Xiaoba's energy.

In addition, the space of the carriage farm needs to be redistributed to accommodate more plants.

After finishing all that, Xiao Ba still needs to help Yu Jing build a new workshop.

He was arguably the busiest person in the entire carriage.

He was responsible for almost all the modifications, and his metal control, which was originally level 2, was upgraded to level 3.

It can also be considered... a training experience for the train conductor.

As for the design of the ammunition depot, Su Huan did not intend to store it in a dedicated carriage, like food.

If someone were to accidentally blow it up, the entire carriage would explode.

Like the water tank and fuel tank, it adopts a distributed design, with each compartment having its own ammunition rack and bulletproof treatment.
