Chapter 454: Copying The Jade Slips
The slips Han Yu had collected contained techniques and information that could not be risked on a single fragile medium.
He needed to copy them into his own storage slips, ensuring nothing would be lost even if one were damaged. After all, even he could not memorize them by heart that well. That meant heading to the Logistics Division's warehouse to buy some.
With that in mind, Han Yu began walking in that direction.
The camp was alive with quiet activity. Some disciples were training in open clearings, their movements sharp against the fading sunlight. Others tended to weapons, polished armor, or sat around fires with bowls of food.
The scent of cooked spirit rice and roasted beast meat drifted thickly across the area, making Han Yu pause for a moment as his stomach gave a low growl. He shook his head lightly and kept moving.
The warehouse was not far, built from sturdy planks and reinforced by talismanic seals to preserve the items inside. Disciples manned the counters, cataloging and distributing supplies to those who came.
Han Yu entered and approached one of the clerks, a young woman with her hair tied neatly back.
"I need two jade slips, mid grade, for information storage," Han Yu said.
The clerk nodded and quickly fetched the items.
They gleamed faintly with a silvery light, each etched with small runes that would channel spiritual energy into their crystalline surfaces. Han Yu paid with the sect merits he had saved and carefully stored the slips in his sleeve.
Though his communication jade slip could also hold information, it was not designed for the kind of vast storage he required.
These special slips were far superior, able to contain entire books worth of content without losing clarity. One would be enough to copy all the jade slips he had acquired from the repository.
The second would serve as his personal journal, a place to record his own notes and reflections. It was a habit he intended to cultivate. With so much to learn, he could not afford to let anything slip from memory.
Stepping back out of the warehouse, Han Yu glanced toward the horizon.
The sun had dipped lower still, and campfires flickered across the camp like scattered stars. He turned the jade slips over in his hand, his expression calm but focused. Tonight, after a good meal, he would begin the work of transferring the knowledge.
It was not glamorous, nor was it the kind of task others would envy. Yet to Han Yu, it was just as valuable as any treasure hunt.
Knowledge, once secured, could not be stolen so easily.
Back at his tent, Han Yu sat cross-legged with the two jade slips before him.
Their faint silver glow reflected the wavering light of the nearby campfires that seeped through the fabric of the tent. He placed one of the original jade slips from the repository on his left, and the newly bought mid grade information slip on his right.
The process of copying information between jade slips was simple, far simpler than the intricate battles and traps they had faced in the underground chambers.
All he needed to do was touch both slips with his hands, let his spirit Qi flow into them, and allow the formations channels inscribed within the crystalline structures to align. Once the resonance began, the information flowed like water down a slanted path.
Han Yu exhaled slowly, steadying his Qi before beginning.
He pressed his left palm to the old slip and his right palm to the new one. The instant his Qi bridged the two, a faint humming filled the air. Threads of pale green light appeared between the slips, like thin strands of silk connecting them.
Then, softly and steadily, the information began to flow.
"Truly convenient," Han Yu muttered to himself.
He watched the flow for several breaths before letting go.
The process was laughably easy when it came to jade slips. This was why they were so widely used for information storage in sects, clans, and even merchant guilds. The efficiency could not be matched by books, parchments, or any other medium.
Han Yu was pleased. If he had needed to copy the information from physical books instead, the work would have consumed endless hours.
Copying from books required an entirely different approach.
He had done it before, and the memory of it still made his head ache faintly. One needed to hold the jade slip in one hand, connect their spirit sense with it, and at the same time read the content of the book with complete focus.
Only then could the words or diagrams enter one's mind and be transferred into the slip. The slip was essentially recording one's thoughts in the exact form they appeared while reading.
For simple text, the task was not difficult.
Letters and characters were straightforward enough, and while the process was draining, it did not strain the mind too heavily. But images were another story altogether. A picture of a landscape, a carefully detailed diagram of a beast's meridians, or a map of terrain—those were not easy to imprint.
On the surface, one might assume that images should be easier than large number of words.
After all, everyone could imagine the likeness of a person or recall the outline of a tree. But perception and memory were rarely flawless. A single curve might shift slightly, a proportion might alter, and colors might lose their vibrancy in the mind's eye.
When such an image was transferred into a jade slip, it could appear warped or incomplete.
This was why many maps and complex diagrams were still written or drawn manually. Accuracy mattered, and relying on imperfect mental impressions risked corrupting the information.
Han Yu recalled the instructors at the Alchemy Peak often berating young disciples who tried to store delicate alchemical diagrams this way. Even a small miscalculation could lead to wasted ingredients or dangerous concoctions.
Even Han Yu had made several mistakes before and had referred to faulty information from his own recorded jade slips that made a few pills explode.
