Doomsday: I Build an Infinite Train

"It doesn't matter, you should consider keeping me."

Ding Junyi's face was calm. She pointed to the workbench in the distance. There were several exquisite petri dishes there, which were plant seeds that Lin Xian and KIKI brought back on the 89th floor. It seemed that Ding Junyi had finished sorting and placed them. Packed.

"Your idea is to cultivate green plants on the train. I happen to be an expert in this field. Although biological academic research and tree planting and cultivation are essentially the difference between theory and practice, there should be no one on this train who is more knowledgeable than me. Suitable for your plan, and you have two Cole 3 creatures The scientific research cabins can be used completely separately. One is used as a research studio for me, and the other is used as a planting cabin. I have made some progress in the research of blood disaster plants, and there is more than one person with superpowers in this car. It can help with experimental observations. If you stay, I can help you explore more areas."

Lin Xian looked at her curiously, "As far as I know, there is a group of operatives from your Dawn Project in Yubei City. Maybe there are people from the Phoenix Society and the Iron Guard Brigade there. Your identity can definitely join the official organization. Why have you always been there?" Want to get in my car."

Ding Junyi tilted her head slightly and looked at Lin Xian seriously, "I remember I told you last night."

"What?"

"I like higher-level physical pleasure. Staying in the dungeon will depress my emotions. What's more, the dungeon is not safe. Don't facts prove this?"

Lin Jing was really a little hard to understand. He frowned and said, "Are you saying that you like the excitement of escape?"

"This possibility is not completely ruled out." Ding Junyi said righteously, "Meeting death on a speeding train towards dawn is more romantic than science, not to mention that I can have science and romance at the same time."

It turned out that such a strict female academic would have such crazy ideas. Lin Xian was secretly stunned. No wonder many people said that those who are calm on the surface have real fanaticism in their hearts. From this director Ding, Lin Xian was shocked. I saw a little bit of it.

"Okay." Lin Xian took a deep breath and responded, "If you still have such thoughts after Yubei City, I will allow you to get on the bus."

"Thanks."

Ding Junyi looked at him, turned around and continued to work seriously.

Lin Xian walked to the carriage at the back, preparing to call up the building and finish the armor of the nuclear-powered locomotive first.

At this time, the light curtain in front of him flashed, and a reminder came from the R\u0026D center.

[The Blue Sky KK-93 reverse osmosis water purifier blueprint has been successfully upgraded and developed, please obtain the new blueprint]

Lin Xian looked happy and immediately chose to get it.

In a flash of glory, there was a brand new blueprint in the R\u0026D center.

[Congratulations, you have obtained the A1 level subcritical reverse osmosis water purifier (blueprint)]

“Subcritical reverse osmosis water purifier?”

Lin Xian looked at the strange blueprint and was dumbfounded. "What is subcritical reverse osmosis? Is it the technology tree of this world?"

Halfway through, he stopped and immediately turned back to find KIKI.

“Girl, let me ask you something, do you know the term subcritical reverse osmosis?”

"You asked me about this..." KIKI frowned, "What is it, related to the water purifier?"

Lin Xian found Ding Junyi again

"Director Ding, do you know about subcritical reverse osmosis water purification technology?"

Ding Junyi turned around and raised her glasses. "RO reverse osmosis method. If you are referring to water purification equipment that relies on reverse osmosis membranes to separate solvents and solutes in solutions under pressure and achieve a filtration accuracy of 0.0001 microns, there are many Laboratories or living areas with high requirements on water quality are using this water purification technology to obtain pure water.”

"The subcritical you are talking about should refer to the state of existence of a substance. In engineering, it means that certain substances exist in the form of a fluid at a temperature higher than its boiling point but lower than its critical temperature and a pressure lower than its critical pressure. material..."

Before she finished speaking, Lin Xian left directly. Ding Junyi took a look, then turned back expressionlessly to continue working.

"Maybe I'm overthinking it. This is a relatively high-end water purification technology, but many people haven't heard of it."

Lin Xian thought for a while and suddenly put the blueprint into the R\u0026D center to see if there was an end to this R\u0026D upgrade.

But when he put the blueprint in, the R\u0026D center directly reminded him: [The mechanical manufacturing level is insufficient and has reached the highest standard of the blueprint]

"All right……"

He opened the preparation factory at this time. At this time, he had obtained a lot of high-energy solid gunpowder in the decomposition space. Now that he wanted to make this water purifier first, he needed the basic materials of the reverse osmosis membrane.

Lin Xian tried to use steel and plastic to convert and prepare it, but found that this reverse osmosis membrane material was a level 2 material. Using level 1 materials to convert the material required for conversion materials suddenly doubled several times!

"I'll go, it's not worth it."

Fortunately, he now has a lot of Level 2 materials, and the material required for this reverse osmosis membrane is not much, so he directly converted it to carbon steel, and finally successfully prepared it in about 20 minutes.

Lin Xian took a deep breath, created a shimmering light in his hand, and countless materials flew out to build in the air.

Soon, a white water purification equipment was slowly manufactured. It was a set of equipment composed of multiple white round tubes and some kind of pressurization device.

"Good guy, looks very high-end."

"Try it first and then talk."

Lin Xian was eager and immediately took the water purification equipment to Car No. 1, connected it to the locomotive's water tank, powered on and started working.

The machine made almost no sound. After waiting for a few seconds, a stream of clear water came out.

"It looks like..."

What a fart.

How can he possibly see the existence of microorganisms with the naked eye?

Lin Xian took the water directly to the No. 3 laboratory cabin and found Ding Junyi again

"Is there a water quality tester in the laboratory? Help me test the quality of this water."

Ding Junyi had no doubts. Hearing Lin Xian's words, he stood up and took Lin Xian's water. He started testing with a water quality detector and quickly came to a conclusion.

"If you want to test water quality, there are many requirements, such as particles, turbidity, organic matter, PH, etc. But I know you are asking about drinking water standards. In conclusion, this water quality belongs to extremely high drinking standards. , but I don’t have effective detection equipment here for the energy carrier of night infection. Maybe the Phoenix Society and the headquarters have made progress, but this is not the field of my research. "

Lin Xian took the water, hesitated for a moment, and then drank it all in one gulp.

The filtration standard of his water purification equipment has exceeded the standard of bottled pure water stored in the car. If there are other invisible infectious effects, there is no other way.

However, there is currently no problem with the bottled water that so many people on the bus have been drinking.

Another point is that the heterogeneous Rubik's Cube helped him isolate the influence of the dark side of the night on the car. Thinking about it this way, I guess that the drinking water problem should be guaranteed.

If this cannot be guaranteed, it is difficult to imagine how other teams can survive.

Relaxing a little, Lin Xian chose to put the blueprint of the M556 light machine gun into the R\u0026D center.

[Please select the research and development direction of this weapon:]

【Firepower】(13 hours)

【Mobile】(09 hours)

【Accurate】(12 hours)

"Firepower!"

Lin Xian responded in his heart as he was familiar with the road.

Suddenly, a line prompting [M556 light machine gun] firepower upgrade (12:59:59) appeared on the time screen, and the countdown began.
