Doomsday: I Build an Infinite Train

Three Spark 26 semi-automatic tactical rifles plus 120 rounds of ammunition can be exchanged for about five days of rations for a ten-man convoy, or 80 liters of gasoline.

However, these weapons combined can only replace two boxes of antibiotics.

In addition, water filtration devices, heating equipment, and communication equipment begin to become more valuable one by one as the apocalypse continues.

As a result, red beans, what the Phoenix Society called the strange blood essence, became a new hard currency for trading. With the invasion of the polar night and the deepening of research, more and more values ​​of this thing began to be discovered.

It can open up communications in the tide of night, peer into the dark world, improve abilities, and detect the spirit value to determine the danger level of an area...

You can imagine how important it is.

Lin Xian was very enthusiastic about the spirit value detector at this time.

If such a thing can be installed on the train, when they stop and rest, the risk of an area can be determined, which can greatly improve the safety of the train during the rest period, and at the same time, it can also allow him to take more time. Used in the exploration of the Heart of Machinery.

It didn't take long for most of the teams to have negotiated some deals with each other. Everyone started exchanging without any lingering.

"This friend."

At this time, the middle-aged man named Xu Jin came over eagerly, and beside him was the woman named Shu Qin.

"If it's convenient, could you take a look at her water purification equipment?"

The woman named Shu Qin had short hair and was not tall, but she looked capable. She said to Lin Xian, "Yes, if you can fix it, I can also provide compensation."

"Let's go take a look first."

Lin Xian said to KIKI, "Girl, you ask the building to bring the things we just discussed and exchange them with the glasses guy for his red beans."

"Okay." KIKI also helped arrange the transaction.

Walking out of the abandoned factory, the wind and snow increased, and the snow began to make a creaking sound when walking on it.

Many survivors of the convoy outside had already put on thick clothes, but some others were still wearing thin clothes and shivering in the snowy night.

Lin Xian followed behind and swept through these convoys of survivors along the way. Almost all of the vehicles were filled with mud. The wet blood stains showed a dark red color in the darkness of the night. All vehicles carrying supplies, water, and children were surrounded. In the center of the convoy, some of the people in charge of guarding had bright eyes, and some had dull expressions.

Shu Qin's fleet is a small one, with only eight vehicles. One of them has a water tank truck mounted on the back of a pickup truck, and a simple rainwater collector made of iron sheets on the roof.

"You cannot drink rainwater from the sky directly, nor can you drink it after boiling it. It must be filtered first, otherwise the water heater will break down quickly and consume a lot of electricity."

Shu Qin patted the iron water tank with a solemn look on his face, "Drinking too much rainwater will not only cause fever and diarrhea due to a large number of bacteria, but it will also cause horrific hallucinations and cause great mental torture."

"Yes." Xu Jin sighed, "We have been looking for water for two days. It turns out that we use a homemade filter to distill it into purified water, but that consumes too much fuel..."

Lin Xian was secretly stunned when he heard this. His Infinity was filled with bottled water that he had collected previously. In addition, he had never received the Phoenix Society's broadcast, so he did not consider this issue at all.

Now that I think about it, I immediately became wary. The Infinity's biggest advantage over these fleets is its loading capacity and protection capabilities, so that it can put a lot of supplies on it.

But the bottled water will run out sooner or later. There are only boiling water and steam generators on the train, and there is no water purification equipment at all.

With the ice shield before, he thought there would be no shortage of water, but he never thought about the hygiene of the water. Fortunately, he just took a lick at that time...

Because there is enough bottled water, there is no shortage in the car that requires him to use ice to make water to drink. Who knows whether the water in this ice shield is generated out of thin air or by condensing the surrounding water vapor. If he gets sick, he may It would be very troublesome. I was too hasty to collect supplies at the outpost late at night. In addition to weapons, food and water, I only found some medical supplies such as hemostatic gauze and iodine.

Even now, even disinfectant drugs such as iodophor have become urgently needed supplies...

Moreover, heating is now required, which consumes a huge amount of electricity.

His mechanical heart power has already put a lot of physical pressure on him, and he still has to run every day...

Damn it, go back and devour all the trailer trains at the back, as well as the unused locomotive, leaving only Qian Yu's armored vehicle and his motorcycle as backup. Try to reduce the load as much as possible, and improve it as soon as possible. Your own mechanical heart level.

"Let me take a look first."

Lin Xian took out the flashlight, climbed directly into the pickup truck, and then pretended to start checking the water purification equipment.

In fact, his [Mechanical Scanning] was quietly turned on, and he was quickly scanning the blueprint of the water purification equipment and checking the problem at the same time.

[Scan successfully, get blue sky KK-93 reverse osmosis water purifier blueprint]

Soon, a set of small holographic blueprints for a water purifier appeared on the light screen in front of Lin Xian.

"So simple?"

"But it requires PVC filter material..."

Lin Xian frowned slightly. He had only swallowed some major metal objects before. Since he activated his decomposition ability, he hasn't swallowed those civilian machinery and home appliances for a long time.

"It seems that we need to find a place to search carefully. Although the mechanical source point may not give you much, you can get some necessary materials."

…

"How's it going? Captain Lin, can you fix it?"

Xu Jin seemed to be more anxious than Shu Qin. He looked like he hadn't had water for a day or two.

So he had just exchanged some weapons and daily necessities for a lot of clean water to solve the urgent problem.

"It may be a problem with the circuit. Can you find me a screwdriver and pliers?"

He said it in a very convincing way. Xu Jin and Shu Qin's eyes lit up immediately.

For Shu Qin, if it can be repaired, she can exchange it for a lot of useful materials.

And for Xu Jin, it really solved the urgent problem.

"Okay, right away!"

Shu Qin quickly asked the team to find a toolbox and handed it to Lin Xian.

"Captain Lin, what do you need to fix this..."

"Just give me twenty cans." Lin Xian came and scanned it. Shu Qin's team didn't have enough supplies. The dozen people looked sad, and it was obvious that they were not rich.

She kindly reminded Lin Xian from the beginning, and told him directly about the information about the supernatural power she knew. Lin Xian had some good feelings for this female captain, and he also got the blueprint of the water purifier, so he didn't ask for too much.

If this set of water purification equipment is repaired, she can exchange at least two red beans worth of supplies from Xu Jin. Twenty cans are not even one-tenth of it, which is really conscientious.

"Really?!" Shu Qin's face was happy. "Great, I'll get it for you right away!"

In fact, Lin Xian asked for cans for another purpose.

When trading at the campfire just now, all his needs did not include supplies and water, and he was driving a train, which easily gave people an impression:

That is, his unlimited fleet is not short of food and water at all.

Lin Xian thought of this, so he deliberately proposed to take cans as a reward, and was a little cautious.

Xu Jin on the side also looked eager, because from Lin Xian's expression, it seemed that the fault was not complicated, which meant that this set of water purification equipment had fewer problems, so he was more relieved.

Without saying anything, Lin Xian used a screwdriver to remove the cover, while frowning and pretending to study and think.

In fact, he had already fixed it when he was running the mechanical heart just now. Although the problem was not big, it would be troublesome for ordinary people to repair it. Thanks to the supernatural ability of Lin Xian's mechanical heart, he only needed to use some materials to decompose the space, repair the circuit board and the water pump motor, and solve the blockage problem at the same time.

"It should be OK..."

Lin Xian was busy for a while, screwed the screws, wiped the sweat, and said to Shu Qin

"Turn it on and try it."

"Okay!" Shu Qin quickly patted the car door and asked the driver of the pickup truck to start the engine and turn on the switch of the water purifier at the same time.

Woo~~

The water purifier started to work normally, and a stream of filtered clean water slowly flowed out.
