As a professional in the prosthetics industry, Teodoro Barrientos had extensive research into the field. He had worked for years in functional design, materials evaluation, and nerve integration techniques. He could tell at a glance whether a prosthesis was functional or just a marketing gimmick.
When he first saw the title in the file: "Robotic prosthetic arm without allergic reactions," his first reaction was complete skepticism.
"This must be a scam," he thought quietly.
There was no mechanical prosthesis in the world that was completely free of allergic reactions. Contact between machinery and human flesh always caused inflammation, rejection, or infection, even under the best clinical conditions. It was an inescapable technical reality.
But as he read further, he was completely speechless.
What he was seeing was not a traditional prosthesis. It was a structure that mimicked not only human movement but also the way the body accepts the implant. It wasn't simply a robotic extension; it was a kind of biomechanical clone, capable of integrating into the nervous system without causing collateral damage.
And the most shocking thing was the technical data that followed.
Currently, the best product on the market was the North American NeuroArm-A5 prosthesis, manufactured by biomechanics giants in collaboration with the military defense industry. It used neural impulses to control the robotic arm through sensors installed directly in the central nervous system.
A single set cost around 290,000 pesos. And even then, it had to be replaced every ten years. Average families could never afford one.
In contrast, the technology Elías Mendoza had given him promised a cost of just 4,000 pesos per unit. It didn't need an external battery; it could operate for decades using only the body's natural bioelectricity.
With technology like that in hand, generating three billion pesos in three months wasn't just possible... it was inevitable.
And if given a little more time… they could monopolize the global market. Tens of billions per year, no exaggeration.
Where did that kid get something like that?
How could he have access to such advanced and revolutionary technology?
Teodoro looked at Elías, who remained silent. For the first time, he looked at him with true admiration.
Elías observed the director's reaction and knew immediately he had convinced him.
"Director Barrientos," he said with a serene smile, "since you believe it's not impossible to generate three billion in three months, then I'm going to give you your first assignment. I want to see the product. How long would it take you to set up a production line with a monthly capacity of one hundred thousand units?"
Teodoro thought for a few seconds before answering.
"Mr. Mendoza... many of the technologies in the USB flash drive are absolutely cutting-edge. Mass-producing them in a short period of time will not be easy."
"For example, the bioenergy technology shown in the plans… simply doesn't exist in Mexico."
"We would have to import it directly from the United States. And that process isn't that simple…"
Teodoro hesitated for a moment before continuing.
"The Americans control all the cutting-edge technology. The products they sell us are limited versions, at absurdly high prices."
"And how much would all this cost?" Elías asked, his composure remaining steady.
"To build a basic production line… we would need about 20 million pesos. But if we aim for a monthly capacity of 100,000 units, the minimum would be 200 million."
"And our plant, Mr. Mendoza… doesn't have that kind of money. Not even close."
For a moment, Elías was silent. He knew money was a real issue. He was the youngest son of the Mendoza clan, with barely enough to operate this plant forgotten by the rest of his family. His maternal lineage couldn't provide him with much more.
But he didn't hesitate for a moment.
"Then use everything we have. Sell, mortgage, take out loans if necessary. I want that first production line built as soon as possible. I need to see that arm manufactured."
"Once we have the product, there won't be a problem with financing," he added. "The money will come. The technology is too good to ignore."
Teodoro nodded respectfully.
Fifteen days passed.
Despite the difficulties and the endless days, the effort paid off. One morning, Teodoro burst into Elías's office excitedly.
"Mr. Mendoza! The first production line is ready. We're going to begin assembling the first robotic arm."
At the time, Elías was studying the biomechanical foundations of the human body. He had spent hours analyzing the biological structure and the key systems he needed to mechanize to achieve the necessary level of transformation.
He knew that the human body could be divided into regions—head, neck, trunk, and extremities—and systems—musculoskeletal, digestive, respiratory, circulatory, immune, reproductive, urinary, and nervous.
The prosthetic arm was just the first step. A 5% transformation.
To reach 98%, he had to completely replace every system in the body. Even the brain. Only then would the system allow for Mechanical Ascension: the complete transfer of consciousness into a fully mechanized body.
But then the philosophical question arose: if a human body is completely replaced, and its mind lives on only as digital code…
is it still human?
He still didn't have an answer.
For now, he could only take it step by step.
"I understand," he finally said. "Take me to see the assembly."
As he entered the production hall, Elias was surprised. He hadn't expected the progress to be so remarkable. Several workers, dressed in dust-proof suits, were operating with precision in front of newly installed assembly lines.
Industrial robots, touchscreens, fine-tuning mechanisms… everything was working.
And in front of him, his first product was being assembled.
A robotic arm, which until recently had been only a series of digital plans, was now taking shape. A stylized design, dark yellow in color, with a smooth texture and even anatomical details that made it similar to a human arm.
At first glance, anyone would think it was real.
If it weren't for the neural port at the end of the arm, it would have been mistaken for an amputated limb.
Teodoro spoke proudly:
"This production line was acquired through European intermediaries, although we know it comes from American technology. It cost 24 million."
"It's one of the most advanced in the world."
"Right now, our workers can produce 300 arms per day. The estimated monthly capacity is 9,000 units."
"We're optimizing shifts to exceed 10,000."
"Look, right now we're assembling a complete model."
"Over here, Mr. Mendoza, we're about to begin the first human tests."
Elías nodded firmly. He knew this moment would mark the beginning of something much bigger.
The biomechanical revolution had begun.
