In the repair shop, Xiang Fan tightened the screws in his hands while silently calculating the data he had copied from Ye Tiandi's mecha system last night. His mind was filled with the complex psychic circuits, the parameters of the Tiandi mecha's core modules, and the advanced designs that were almost impossible to see on a Jindan-level mecha. Even as his hands moved mechanically, his mind had already drifted away, completely immersed in a pile of complex calculations.

Engineer Hong came over from the other side and saw Xiang Fan tightening a screw three times, then tightening it back three times. He couldn't help but frown: "Xiao Xiang, what's wrong with you? Did something happen at home? Or are you in love and have lost your soul?"

Xiang Fan snapped back to reality, his hand shaking so much that he nearly dropped the screw. He quickly waved his hand away, "No, no! I just saw an engine part online recently. The parameters were really weird, and I accidentally got caught up trying to figure out its details."

Upon hearing this, Engineer Hong burst into laughter, plopped down on a nearby workbench, and fanned himself with a worn piece of metal. "Xiao Xiang, we repairmen shouldn't just focus on those virtual world parameters. Those parameters are just theoretical, but real combat is another matter altogether."

Engineer Hong fanned the machine with a metal plate, raised his finger, and said earnestly, "Look, the theoretical data of the engine is always an ideal state. In the spiritual battlefield, the system automatically calculates the maximum output data, zero loss, and perfect operation. But in reality, how can it be so simple?"

He casually picked up a scrapped psychic conduit and gestured, "Take this conduit, for example. When psychic energy flows, micro-losses, impurities, and even the decline in service life within it will all affect the output rate. Not to mention the circuit design issues. Sometimes, adding an extra conduit in the belief of optimization actually increases psychic energy loss. Even more ridiculous is that the operator's skill determines the mecha's ability to exert its full power."

Engineer Hong put down the parts and patted Xiang Fan's shoulder meaningfully. "Young man, don't always think about how to maximize the parameters. Change your perspective and look for breakthroughs in loss and structure to truly improve performance."

After saying that, he stood up unsteadily, fanning himself while lamenting the stuffy heat in the workshop. He picked up a can of iced psychic drink, squinted his eyes and leaned back in his chair, enjoying the rare moment of coolness.

Xiang Fan stood there blankly, pondering Hong Gong's words. Suddenly, his eyes lit up and he muttered to himself, "That's right! Parameters are static, but people are alive, and data is changing!"

He looked down at the engine component he was repairing, and began to simulate the entire engine's structure in his mind. As if a holographic projector had appeared before his eyes, he could clearly "see" the path of psychic energy flow. Psychic energy circuits ran through the engine like blood vessels, and the energy transmission, loss points, and efficiency blind spots in the operation were clearly visible.

Xiang Fan put down his tools, closed his eyes, and gestured in the air with his hands, as if controlling an invisible virtual projection. His mind raced, simulating, analyzing, and calculating. He repeatedly adjusted the energy circuits and optimized the transmission methods, precisely eliminating all unnecessary energy loss and forming a brand new psychic energy transmission system.

"If we reduce the loop redundancy here... optimize the transmission angle... compress the rune array..." Xiang Fan muttered to himself, his fingertips lightly sliding in the air, like a craftsman creating new things in the virtual space.

Finally, he suddenly opened his eyes, a smile on his face as he stared at the engine component in his hand. "If it is rebuilt according to this optimization plan, not only can the spiritual energy output reach the peak of the Golden Core stage, but it can even... reach a higher level."

Xiang Fan quickly picked up pen and paper and transformed the inspiration in his mind into incredibly precise circuits. He carefully considered and repeatedly calculated every psychic transmission path and every energy node. His pen tip flew across the paper, and soon, a complex yet highly logical diagram of the psychic engine improvement appeared on the page.

He stared at the blueprint with a fiery gaze, muttering to himself, "If this is fully built, the mechas of Zero, Shadow Killer, Black Tortoise, Sky, Youyu, and Gu Master can all be upgraded to peak Golden Core-level psychic parameters. While still not as good as the mecha we encountered last night, it's incredibly close."

Xiang Fan grew increasingly excited as he thought about it. He quickly turned a new page and began fine-tuning certain key details, deducing the optimal energy flow structure. He was so immersed in it that he didn't even notice when Hong Gong approached.

The table was tapped gently. Hong Gong stood by with a smile, watching him with interest: "Xiao Xiang, what are you drawing? You look so focused, like you're studying an ancient technique."

Xiang Fan's head shot up, his hands shaking as he nearly crumpled the blueprint into a ball. He chuckled dryly and tucked the blueprint under his elbow. "Uh... nothing, just drawing for fun."

Engineer Hong unceremoniously reached out and pulled out the blueprint. He examined it carefully for a few seconds, and raised his eyebrows slightly: "This design... has something interesting."

Xiang Fan's heart tightened, fearing that he would be asked too many questions, and he quickly waved his hands: "Just thinking about it and practicing."

Engineer Hong narrowed his eyes, looked up at him, and a smile played on his lips. "Boy, you're really not being honest. This thing doesn't seem like just a random idea." He turned the blueprint over, examined it against the light, and said in admiration, "The psychic energy transmission is optimized, and the energy loss is halved. This circuit design is far superior to the junk we have in the workshop."

Xiang Fan felt a little embarrassed by the compliment and said awkwardly, "Engineer Hong, please stop praising me. It's just an immature idea. It's really not that great."

Engineer Hong laughed heartily and slapped the blueprint back into his hands. "Don't underestimate yourself. If you could build this design and take it to the higher-ups, it would absolutely astound those elite engineers." He paused and sighed. "It's a shame our workshop doesn't have the resources. Otherwise, I'd love to help you try."

After Engineer Hong finished speaking, he fanned the metal sheet and staggered away, muttering, "What a loss! If our workshop could handle such high-end work, we would have made a fortune long ago."

Xiang Fan sat there, looking down at the blueprint in his hand, feeling an unprecedented urge surge within him. He gently stroked the edge of the blueprint, thinking, "Perhaps this blueprint can really change a lot of things. But I can't do that right now. If only I had more resources..."

He looked up at the door of the workshop. Outside the door was a busy industrial area. Psychic lights flickered between the tall buildings, and aircraft shuttled back and forth. Under the distant sky, the headquarters building of Qixing Company could be vaguely seen, like an insurmountable tower.

"One day, I will stand on that place." Xiang Fan said to himself with a firm look.

However, he gave a wry smile the next second, folded the blueprint, and stuffed it into his pocket: "But before that... I better finish today's repair task first, otherwise even the money for food will become a problem."

He shook his head, sighed, and continued to work on the mecha parts in front of him. The workshop was still filled with the familiar roar of machines and the clashing of iron, but in Xiang Fan's heart, a seed of hope had quietly taken root and sprouted.
