I can upgrade the shelter-Chapter 601 - 499: Protesting the Idiotic Limited-Free Activity

"Xin, why do you have such an expression? Have you encountered something troubling?" Mo Qingyan noticed the strange expression on Chen Xin's face when he returned from outside and couldn't help but ask with concern.

"Oh, it's nothing, just a small matter." Chen Xin said this, but his expression didn't match the words, suggesting otherwise.

Instead, he gave the impression of having encountered something embarrassing, like everyone's own past they prefer to keep hidden yet find awkward beyond measure.

Mo Qingyan roughly understood Chen Xin's expression, so she didn't pursue further questioning.

However, Chen Xin's father, noticing his son's abnormal expression, asked with equal concern, "Is it something at work? Did you make some mistake at work?"

"No, just a small matter, I can handle it myself." Chen Xin put on a nonchalant look, as if it were indeed a trivial issue not worth mentioning.

Seeing this demeanor, his father, familiar with his temperament, said no more, simply advised him, "Don't be afraid of trouble when there's a problem at work, actively face and handle it. Since the matter has already happened, you should first consider solving it, rather than devising ways to evade responsibility."

"I understand, Dad." Chen Xin nodded, his expression shifting slightly, seeming to shed a burden.

——————————————

After finishing his meal and returning to his room, Chen Xin sat at his desk with a wry smile.

In fact, Mo Qingyan and his father had already guessed that something had happened to him, but they simply refrained from probing further to spare his dignity.

The matter wasn't severe at all; it was just a minor accident, akin to making a fool of himself, rather than an actual work error.

Actually, the issue lay with the mining Titan designed by Chen Xin earlier; he had single-mindedly tried to utilize the existing prototype, neglecting the significant differences between open-pit and underground mining.

Underground mining primarily requires digging tunnels and crushing rocks to obtain ore.

In this mining process, before the disaster, due to technological advancements and increased mechanization, mechanical equipment was extensively used for mining operations.

Manual use of air picks to crush rocks was relatively rare before the disaster, adopted only by smaller mines unable to afford large machinery, opting for more primitive mining methods.

But after the 21st century, such small mines became increasingly rare.

Post-disaster, however, many machines couldn't operate under extremely cold conditions of minus dozens of degrees, being originally designed for different environments, rendering many unusable.

Coupled with the country's weakened industrial strength, producing large-scale machinery suitable for current conditions in the short term was impossible, leaving many mines to persist with relatively primitive manual mining methods.

The previous Researcher designed the mining Titan for this reason, equipping it with an air pick, and simplified it to an Exoskeleton paired with an air pick, balancing the ore bin with supporting feet.

However, open-pit mining wasn't like this.

For open-pit mines, direct mountain excavation followed by rock crushing was used for mineral extraction.

Technological advancements have long transformed blasting into direct digging; no matter how hard the rock, it cannot withstand the powerful cutting brought by hard alloy picks and hydraulic aids.

This is undoubtedly more practical and efficient than the hammering methods conceived by Chen Xin.

Despite environmental constraints limiting open-pit mines' operations, it's not feasible to replace digging heads with air hammers and brute force to smash ores.

Indeed, ores need to be crushed, but not to the extent of pulverization.

This awkwardness stemmed from Chen Xin; he sent his completed mining machinery design to the relevant mining departments, which hesitated to respond, sending some mining machinery data as references to avoid harming his dignity. 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

Upon seeing these materials, Chen Xin understood exactly where he went wrong; he realized his ideas were quite naive.

Fortunately, this was merely a design draft, not finalized for production, so it was simply his own embarrassment, allowing for timely revisions and adjustments without much consequence.

The biggest issue was simply Chen Xin making a laughingstock of himself, fortunately without anyone ridiculing him over such matters.

The mining department still held great interest in his new design, actively providing all sorts of mining equipment data to help him design usable open-pit mining equipment.

After referencing the mining department's data, Chen Xin developed new ideas, planning to overhaul his original design completely.

Replacing the air hammers with digging heads, placing a large roller-like digging head at the front, directly excavating and crushing ores, then sending them to the ore bin at the back of the machine, simplifying the structure.

At least, the mechanical claw originally used for ore collection could be removed, simply requiring an internal conveyor belt to directly dump the excavated ores onto it, transporting them to the ore bin effectively.

Actually, the former mining machinery adopted this design, a single machine with complex digging, transporting the crushed ores directly via conveyor belts or large trucks, achieving high efficiency.

The only issue was the existing large-scale mining machinery struggling to withstand current conditions, often freezing and difficult to operate.

Considering this, Chen Xin thought perhaps modifying existing mining machinery was more practical than stubbornly pursuing mining Titans.

Yet, since the project was underway, abandoning it halfway lacked reason; he decided to see his work through.

Moreover, the design wasn't entirely flawed; by correcting the unreasonable aspects, it remained usable.

With this in mind, Chen Xin reinvigorated his spirit, opened his computer, retrieved the data previously sent by the mining department, and planned to conduct serious study and determine how to revise his design.

While Chen Xin immersed in work, his door quietly opened, and Qin Lan entered carrying a late-night snack.

Without disturbing his work, she placed the food aside and quietly exited.
