I live in the Martian wilderness!

"Lieutenant Colonel, the issue you were worried about yesterday, that 'water vapor will damage the light fixtures,' does exist, but it's not entirely true."

Xuanjian immediately brought up the final design file of the [GZ-05 Universal Illumination Module] on the screen.

"The design unit of this module, the 13th Research Institute of China Electronics Technology Group Corporation, had already taken into account the extreme working conditions of deep space agriculture."

"The final production version of the GZ-05 in 2047 adopted an IP68+ fully sealed structure and an immersion liquid cooling solution."

The animation on the screen demonstrates that each light strip is encapsulated in a highly transparent quartz glass tube, and the power interface uses a submarine-grade waterproof connector. The waste heat generated can be directly and efficiently conducted to the surrounding liquid medium.

"Simply put, the original design concept of this light array was to be able to be thrown directly into the water for use."

"Its waste heat can also help heat the culture medium, making it a perfect energy cascade utilization solution."

Gu Yu stared blankly at the screen, at the problem that should have been incredibly complex, which had been easily solved by such a simple and straightforward design. For a moment, he was both amused and exasperated.

The "hand-rubbed diamond" solution that I racked my brains to come up with looks like an amateur showing off his skills in the face of real industrial design.

"So," he muttered to himself, "we don't need any diamond modification at all?"

"Yes, Lieutenant Colonel. We only need the simplest lid."

Xuanjian switched the screen, displaying a new, simpler, and more efficient solution.

"We can use the Shengong module to print a carbon fiber sheet, which can be placed on the track pool like a blanket, thus perfectly solving the problems of water evaporation and carbon dioxide emission."

Gu Yu stared at this extremely simple solution and remained silent for a long time.

The excitement and confidence on his face slowly faded, replaced by a profound self-reflection.

Finally, he let out a long sigh of relief, a slightly bitter but relieved smile appearing on his face.

"Okay... alright." It was less like she was speaking to Xuanjian and more like she was talking to herself. "Sometimes the wisest approach is to trust the wisdom of everyone."

He leaned against the control panel, a hint of worry flashing in his eyes.

"Xuan, I need to reflect on this."

Gu Yu's voice turned serious. "These past fourteen days on Mars have gone too smoothly."

"Mining, drilling wells, building walls... every step was textbook perfect. My mindset started to falter."

"I started to subconsciously treat my superpowers as a universal key to solving all problems, and even...enjoyed this feeling of human beings conquering nature."

"They even started pursuing more complex and technically advanced solutions, while ignoring the simplest and most reliable engineering principles."

He shook his head as he looked at the "ingenious" diamond solution on the screen.

"If I hadn't asked you just now, and instead directly expended a huge amount of mental energy to create those diamond modifications, it would have been a serious waste of resources and a decision-making error."

"This is something we absolutely cannot allow to happen right now! On Mars, any mistake could be fatal."

He turned around and looked directly at Xuanjian's main camera, his eyes extremely serious.

"Xuan, I am now issuing you a long-term order with the highest priority."

"From now on, whenever I propose any decision that deviates from the optimal engineering path and is heavily influenced by personal subjectivity, I authorize you to interrupt me immediately and raise questions."

"Regardless of my attitude at the time, you must stick to your data and logic. Understand?"

"Instructions entered, Lieutenant Colonel." Xuanjian's voice was as calm as ever. But it did not end the conversation immediately.

"However, Lieutenant Colonel, you don't need to blame yourself too much. According to the original mission plan, Project Fireseed was a systematic project requiring a six-person team to work together."

Xuanjian displayed the avatars of the other five team members and their main responsibilities on the screen:

Colonel Qin Manying: Commander-in-Chief, responsible for strategic decision-making.

Lieutenant Colonel Wang Yang: Chief Geologist, responsible for resource exploration.

Major Guo Peng: Power systems expert, responsible for energy management.

Major Wang Qing: Mechanical Engineer, responsible for equipment maintenance.

Major Lin Yishui: Medical officer and biologist, in charge of life science experiments.

"According to the original plan, Major Lin Yishui should have provided the optimal biological solutions for issues such as the selection of light sources and the construction of biological culture environments."

"And you, as the chief engineering officer and pioneer, your core responsibility is execution—that is, how to use the most efficient engineering methods to realize the needs put forward by biologists."

"The diamond solution you just proposed is a brilliant idea from an engineering perspective. However, it is not the optimal solution under a comprehensive evaluation from both biological and energy perspectives."

Xuanjian's logic is clear and fluent, yet it carries a unique comforting power.

"You now hold six positions: commander, engineer, geologist, biologist, and doctor."

"Under such immense pressure, it is entirely logical to have blind spots in knowledge of non-core professional areas."

"This is not your mistake, but an inevitable result of the abnormal task mode."

Gu Yu listened quietly, and the self-blame and regret in his heart dissipated somewhat after Xuan Jian's rational analysis.

Yes, he almost forgot that he shouldn't have been alone.

He not only has to operate an excavator, but also understand biology, chemistry, and geological maps; he even has to treat his own illness.

"I understand, Xuan." Gu Yu straightened his back again. "Thank you."

"However," his eyes sharpened again, "having multiple roles is not an excuse for making mistakes; on the contrary, it places higher demands on me."

"I am first and foremost a soldier, and only then an engineer with special abilities. My mission is survival, not showing off my skills."

"Now that I am the commander-in-chief, every decision I make must be based on the overall situation and undergo the most rigorous and calm evaluation."

"For us now, there is no room for excusing, only 'survival' or 'death'."

"Xuan, from now on, I will reserve at least ten minutes of cooling-off period before making any major decision, to conduct cross-validation and risk assessment with you."

"I want to ensure that every instruction I give is based on the optimal solution through data and logic. I must eliminate any decision-making errors caused by personal emotions or ingrained thought patterns."

"Review complete." Gu Yu regained his efficient demeanor. "Xuan, please continue to refine and supplement today's plan."

"Lieutenant Colonel, based on your final decision and in accordance with the principle of cross-validation, the [Shennong Project - Hardware Deployment] process has been re-optimized."
