"It doesn’t matter, you should consider keeping me."
Ding Junyi’s expression remained unchanged as she pointed to a workbench in the distance. On it, there were several delicate culture dishes containing plant seeds that Lin Xian and KIKI had brought back from the 89th floor, which appeared to have been classified and packed by Ding Junyi.
"Your idea is to cultivate green plants on the train, and as it happens, I specialize in this area. Although biological academic research and the cultivation of trees and plants are essentially different in theory and practice, there’s probably no one more suitable than me to carry out your plan on this train. Besides, you have two Cole 3 Type Biological Research Cabins, which can be used separately--one as my research studio and the other for plantation. I’ve already made some progress in the research of the Blood Calamity Disaster Plant, and with more than one Superpower User on board to assist with experimental observation, keeping me around could help you explore more areas."
Lin Xian looked at her curiously, "As far as I know, there is a team from the Dawn Plan in Yu Bei City, and there might also be people from the Phoenix Society and the Iron Guard Brigade. With your status, you could completely join the official organization. Why do you keep wanting to get on my train?"
Ding Junyi tilted her head slightly and looked earnestly at Lin Xian, "I believe I told you last night."
"I enjoy higher levels of physiological pleasure. Staying in the Underground City would suppress my emotions. Moreover, the Underground City isn’t safe, as we’ve seen, isn’t that right?"
Lin Xian found it somewhat difficult to understand and frowned, "Are you saying you’ve developed a liking for the thrill of fleeing?"
"It’s not entirely out of the question," said Ding Junyi with conviction. "Welcoming death on a train racing towards dawn is more romantic than science. Besides, I can have both science and romance."
It turns out that such a prim and proper female scholar could have such crazy thoughts. Lin Xian was secretly amazed; it’s no wonder many people say that those who appear calm on the surface harbor true passion within. In Director Ding, Lin Xian saw a glimpse of this.
"All right," Lin Xian took a deep breath and responded, "If you still feel the same way after we pass Yu Bei City, I’ll agree to let you on board."
Ding Junyi glanced at him, then turned around and resumed working seriously.
Lin Xian walked towards the rear of the train, ready to wake up Building and get the armor for the nuclear-powered locomotive in order.
At that moment, a notification flashed on the light screen in front of him from the Research and Development Center.
[Blue Sky KK-93 Water Purifier Blueprint Upgrade Successfully Developed. Please Retrieve New Blueprints.]
Lin Xian’s face lit up, and he immediately chose to retrieve them.
A flash of light, and a brand-new blueprint was present in the Research and Development Center.
[Congratulations, you have obtained the A1 Grade Subcritical Reverse Osmosis Water Purifier (Blueprint).]
"Subcritical Reverse Osmosis Water Purifier?"
Lin Xian looked at the strange blueprint, slightly dumbfounded, "What’s subcritical reverse osmosis? Is that even part of the technology tree of this world?"
He stopped halfway, turned back immediately, and went looking for KIKI.
"Hey girl, I have a question. Do you know what subcritical reverse osmosis is?"
"That’s a stumper for me..." KIKI frowned, "What is it, something related to water purifiers?"
Lin Xian went to see 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, refers to the separation of solvent and solute in a solution through a reverse osmosis membrane under pressure, purifying water to a filtration precision of 0.0001 micrometers. Many laboratories and living areas with high water quality standards use this water purification technology to obtain pure water."
"As for the subcritical condition you’re talking about, it should refer to the state of existence of a substance. In engineering, it refers to some substances that exist in a fluid state above their boiling point but below their critical temperature, with pressure below their critical pressure..."
Before she could finish speaking, Lin Xian left. Ding Junyi glanced at him, then turned back with an impassive face and continued working.
"Maybe I’m overthinking it. It’s just a more advanced type of water purification technology that many people haven’t heard of."
After giving it some thought, Lin Xian suddenly put the blueprint back into the Research and Development Center to see if there was a limit to this development upgrade.
But when he put the blueprint in, the Research and Development Center directly prompted him: [Mechanical Manufacturing level insufficient, has reached the highest standard of this blueprint]
At this time, he opened the Preparation Factory, where his Decomposition space had already acquired a good amount of High Energy Solid Propellant, and now he wanted to produce the water purifier, which required the basic material of reverse osmosis membrane.
Lin Xian tried to use steel and plastic for the conversion, only to find that this reverse osmosis membrane material was a level 2 material, and the requirement for the conversion materials spiked exponentially when using level 1 materials!
"Damn, this really isn’t cost-effective."
Luckily, he had plenty of level 2 materials at his disposal, and not much was needed for the reverse osmosis membrane, so he went ahead with the conversion using carbon steel, and after about 20 minutes, he finally succeeded in preparation.
Lin Xian took a deep breath, a faint light of creation shone from his hands, and numerous materials flew out and assembled in the air.
Soon, a white water purification device was slowly crafted, a system consisting of several white cylindrical tubes and some sort of pressurizing apparatus.
"Nice, it looks pretty high-end."
"Let’s test it out first."
Eager in his heart, Lin Xian immediately took the water purification device to Carriage 1, connected it to the locomotive’s water tank, and started working it after turning on the power.
The machine made virtually no sound, and after a few seconds of waiting, a stream of clear, purified water flowed out.
As if he could see microbes with his naked eyes.
Lin Xian directly took the water to Laboratory Cabin 3 and once again found Ding Junyi
"There should be a water quality testing instrument in the lab, help me check the quality of this water."
Ding Junyi had no questions, heard Lin Xian’s request, stood up, took the water from Lin Xian, and began testing with the water quality testing instrument. It didn’t take long to come to a conclusion.
"If you want to check the water quality, there are many requirements: particle size, turbidity, organic matter, pH, etc. However, I know you’re asking about the standards for drinking water. From the results, this water is of a very high drinking standard. But I don’t have the equipment here to effectively test for energy carriers of the night contagion. Maybe the Phoenix Society or headquarters have made progress already, but this is not my field of study."
Lin Xian took the water, hesitated for a moment, and then drank it all in one gulp.
The filtering standard of his water purifier had already surpassed that of the bottled purified water reserves on board. If there were other invisible contaminating effects, there would be nothing else he could do.
However, everyone on board had been drinking the bottled water so far with no issues.
Another point was that the Heterogeneous Rubik’s Cube had helped him isolate the dark forces of the night from influencing the interior of the vehicle. With this thought, he guessed that the drinking water issue should be assured.
If this couldn’t be guaranteed, it was hard to imagine how other teams were going to survive.
With his mind slightly at ease, Lin Xian now chose to put the blueprint of the M556 light machine gun into the Research and Development Center.
[Please choose the development direction of this weapon:]
[Firepower] (13 hours)
[Mobility] (09 hours)
[Precision] (12 hours)
Lin Xian mentally responded, well-practiced.
Immediately, a prompt appeared on the light screen [M556 light machine gun] Firepower upgrade (12:59:59), beginning the countdown.
