Qiahao  I’m an expert in this field. Although biological research and tree cultivation are fundamentally theoretical versus practical distinctions, no one on this train is better suited to carry out your plan than I am. Moreover, you have two Keer 3-type bio-research carriages—you can use them separately: one as my lab, the other as a growth chamber. I’ve already made progress in studying the Blood Plague Plants, and with multiple psychics on board who can assist with experimental observation, keeping me will help you expand into many more areas.”\u003C\u002Fp>\n\u003Cp>Lin Xian looked at her curiously. “As far as I know, your Dawn Project has an operational team in Yubei. There might even be Phoenix Society and Taitiewei personnel there. Your credentials could easily get you into an official organization—why do you keep insisting on boarding my train?”\u003C\u002Fp>\n\u003Cp>Ding Jun tilted her head slightly and stared intently at Lin Xian. “I think I told you last night.”\u003C\u002Fp>\n\u003Cp>“What?”\u003C\u002Fp>\n\u003Cp>“I crave higher-grade physiological pleasure. Living underground suppresses my emotions. Besides, underground cities aren’t safe—doesn’t the evidence prove that?”\u003C\u002Fp>\n\u003Cp>Lin Xian genuinely struggled to understand. He frowned. “You mean you’ve grown fond of the thrill of fleeing?”\u003C\u002Fp>\n\u003Cp>“I can’t entirely rule out that possibility,” Ding Jun declared solemnly. “Facing death on a train racing toward dawn is more romantic than science itself. And besides—I can have both science and romance.”\u003C\u002Fp>\n\u003Cp>So this rigid, top-tier female scholar actually harbored such a wild idea. Lin Xian inwardly marveled. No wonder so many said those who appear utterly composed harbor true fervor within—here, he’d glimpsed a hint of it in Director Ding.\u003C\u002Fp>\n\u003Cp>“Alright,” Lin Xian sighed deeply. “If you still feel this way after we reach Yubei, I’ll let you board.”\u003C\u002Fp>\n\u003Cp>“Thank you.”\u003C\u002Fp>\n\u003Cp>Ding Jun glanced at him, then turned back to her work with focused intensity.\u003C\u002Fp>\n\u003Cp>Lin Xian walked toward the rear carriages, planning to wake up Daliu and get the nuclear locomotive’s armor sorted first.\u003C\u002Fp>\n\u003Cp>At that moment, a light screen flashed before his eyes—a reminder from the R&D Center.\u003C\u002Fp>\n\u003Cp>【Blue Sky KK-93 Reverse Osmosis Water Purifier blueprint upgraded and developed successfully. Please retrieve the new blueprint.】\u003C\u002Fp>\n\u003Cp>Lin Xian’s face lit up. He immediately selected “Retrieve.”\u003C\u002Fp>\n\u003Cp>A flash of light—another brand-new blueprint appeared inside the R&D Center.\u003C\u002Fp>\n\u003Cp>【Congratulations. You have obtained A1-class Subcritical Reverse Osmosis Water Purifier (blueprint).】\u003C\u002Fp>\n\u003Cp>“Subcritical reverse osmosis water purifier?”\u003C\u002Fp>\n\u003Cp>Lin Xian stared at the strange blueprint, dumbfounded. “What the hell is subcritical reverse osmosis? Is this some new tech tree from this world?”\u003C\u002Fp>\n\u003Cp>He halted mid-step, then immediately turned back and found Kiki.\u003C\u002Fp>\n\u003Cp>“Hey, kid, I’ve got a question—have you heard of ‘subcritical reverse osmosis’?”\u003C\u002Fp>\n\u003Cp>“You’ve got me there…” Kiki frowned. “What’s that? Something related to water purifiers?”\u003C\u002Fp>\n\u003Cp>Lin Xian went again to find Ding Jun.\u003C\u002Fp>\n\u003Cp>“Director Ding, do you know what subcritical reverse osmosis water purification technology is?”\u003C\u002Fp>\n\u003Cp>Ding Jun turned, adjusted her glasses. “If you mean reverse osmosis using membranes under pressure to separate solvent from solute in a solution, achieving filtration precision of 0.0001 micrometers—that’s a purification method widely used in high-purity water labs and living quarters.”\u003C\u002Fp>\n\u003Cp>“And ‘subcritical’ likely refers to the state of matter—in engineering, it describes substances existing as fluids at temperatures above their boiling point but below their critical temperature, with pressure below their critical pressure…”\u003C\u002Fp>\n\u003Cp>Before she finished, Lin Xian walked away. Ding Jun glanced after him, then turned back silently to resume her work.\u003C\u002Fp>\n\u003Cp>“Maybe I’m overthinking it. It’s just a high-end water purification tech—most people just haven’t heard of it.”\u003C\u002Fp>\n\u003Cp>Lin Xian thought for a moment, then placed the blueprint back into the R&D Center to see if this upgrade had any limit.\u003C\u002Fp>\n\u003Cp>But as soon as he did, the R&D Center immediately notified him: 【Mechanical Manufacturing level insufficient. This blueprint has reached its maximum standard.】 “Alright…”\u003C\u002Fp>\n\u003Cp>He opened the Fabrication Factory. His decomposition space now held a decent stockpile of high-energy solid propellant. To build this purifier, he needed the base material for the reverse osmosis membrane.\u003C\u002Fp>\n\u003Cp>Lin Xian tried converting steel and plastic—but discovered this membrane material was a Level 2 material. Converting it from Level 1 materials multiplied the input requirements by several times!\u003C\u002Fp>\n\u003Cp>“Damn, this isn’t worth it.”\u003C\u002Fp>\n\u003Cp>Fortunately, he had plenty of Level 2 materials already, and the membrane required only a small amount. He directly converted carbon steel. After roughly twenty minutes, he succeeded.\u003C\u002Fp>\n\u003Cp>Lin Xian took a deep breath. A faint glow appeared in his hands; countless materials flew into the air and assembled themselves.\u003C\u002Fp>\n\u003Cp>Soon, a white water purifier slowly formed—a device composed of multiple white cylindrical tubes and some pressurization apparatus.\u003C\u002Fp>\n\u003Cp>“Damn, looks high-end.”\u003C\u002Fp>\n\u003Cp>“Let’s test it first.”\u003C\u002Fp>\n\u003Cp>Eager, Lin Xian carried the purifier to Carriage 1, connected it to the locomotive’s water tank, powered it on, and activated it.\u003C\u002Fp>\n\u003Cp>The machine made almost no sound. After a few seconds, a thin stream of clear purified water flowed out.\u003C\u002Fp>\n\u003Cp>“Looks…”\u003C\u002Fp>\n\u003Cp>!\u003C\u002Fp>\n\u003Cp>Look at shit.\u003C\u002Fp>\n\u003Cp>Microorganisms? How the hell could his naked eyes see them?\u003C\u002Fp>\n\u003Cp>Lin Xian took the water straight to Laboratory Carriage 3 and found Ding Jun again.\u003C\u002Fp>\n\u003Cp>“You’ve got a water quality analyzer in the lab, right? Check this water for me.”\u003C\u002Fp>\n\u003Cp>Ding Jun asked no questions. She took the water from him immediately and ran the test. She quickly concluded.\u003C\u002Fp>\n\u003Cp>“If you’re testing water quality, there are many parameters—particles, turbidity, organics, pH, etc. But I know you’re asking about drinking standards. In terms of those, this water meets an extremely high drinking standard. However, I have no equipment capable of detecting the energy carriers of Night Plague infections. The Phoenix Society or Headquarters might have progress—but that’s outside my research domain.”\u003C\u002Fp>\n\u003Cp>Lin Xian took the water, hesitated a moment, then drank it all at once.\u003C\u002Fp>\n\u003Cp>This purifier’s filtration standard already surpassed the bottled purified water stored on the train. If there were any invisible infectious effects, there was nothing else he could do.\u003C\u002Fp>\n\u003Cp>But so far, everyone on the train had been drinking bottled water with no issues.\u003C\u002Fp>\n\u003Cp>Also, the Hetero-Cube had blocked the Night’s dark influence from entering the train. If that was true, perhaps the drinking water was safe.\u003C\u002Fp>\n\u003Cp>If even this couldn’t be guaranteed, he couldn’t imagine how any other convoy survived.\u003C\u002Fp>\n\u003Cp>Slightly reassured, Lin Xian now placed the M556 light machine gun blueprint into the R&D Center.\u003C\u002Fp>\n\u003Cp>【Select weapon development direction:】\u003C\u002Fp>\n\u003Cp>【Firepower】 (13 hours)\u003C\u002Fp>\n\u003Cp>【Mobility】 (9 hours)\u003C\u002Fp>\n\u003Cp>【Accuracy】 (12 hours)\u003C\u002Fp>\n\u003Cp>“Firepower!”\u003C\u002Fp>\n\u003Cp>Lin Xian responded instinctively.\u003C\u002Fp>\n\u003Cp>Instantly, a prompt appeared on the screen: 【M556 Light Machine Gun—Firepower Upgrade (12:59:59)】. Countdown began.\u003C\u002Fp>\n\u003Cp>New book launch, first time reaching 2000 monthly votes. Thank you all for your support.
