"How do you 'restore' the Letter Token?" 𝑓𝑟ℯ𝘦𝓌𝘦𝘣𝑛𝑜𝓋𝑒𝓁.𝑐ℴ𝓂 After several days of exploration and a review of numerous Formation Books, combined with his own understanding of the Beacon Fire Yuan Magnet Formation, Mo Hua had some ideas. Restoring the Letter Token was based on the principle of "Yuan Magnetic Letter Transfer." The Yuan Magnetic Formation in ordinary Jade Slips was a Single Formation. However, the Yuan Magnetic Formation involved in the Letter Token was a Compound Formation. The Compound Yuan Magnetic Formation required the Formation Pivot to control the transfer of Magnetic Patterns between different Yuan Magnetic Formations and the conveyance of messages. Through the Letter Token in his hand, Mo Hua discovered: If he wanted to send a message to Uncle Gu, he first had to use his Divine Sense to manipulate the Magnetic Ink and reveal the text. As the text appeared and the Magnetic Ink changed, it would cause the Unfixed Magnetic Patterns to change. These Unfixed Magnetic Patterns would then be conveyed through subtle Secondary Thunder Patterns to the Fixed Magnetic Patterns. The control of the Formation Pivot within the Fixed Magnetic Patterns and the sensing of Magnetic Patterns would transmit these pattern changes to another Letter Token within the same Compound Formation—the one belonging to Uncle Gu and the underlying Fixed Magnetic Patterns in his "Letter Token." Afterward, Uncle Gu's Letter Token, via the underlying Fixed Magnetic Patterns, would receive the sensing. Then, through the processes of Secondary Thunder Patterns, Unfixed Magnetic Patterns, Magnetic Ink, and text, this sensing would manifest as text. The entire process was the transmission of text information in one Letter Token, from the surface to the core, successively through Magnetic Ink, Unfixed Magnetic Patterns, Secondary Thunder Patterns, Fixed Magnetic Patterns, and Formation Pivot sensing, to another Letter Token. The other Letter Token, from the core to the surface, through the underlying Fixed Magnetic Patterns, Secondary Thunder Patterns, Unfixed Magnetic Patterns, Magnetic Ink in succession, ultimately manifested as text. When put together, this was a complete, complex cycle of the Compound Yuan Magnetic Formation. Mo Hua sighed. These were not things he could learn at present. With his current level of Divine Sense, he could not learn this type of compound Yuan Magnetic Formation method. At least not until he had reached the Seventeen Patterns, Foundation Establishment Late Stage. Fortunately, to "restore" the text of the Letter Token, there was no need to master the entire set of Yuan Magnetic sensing in the Compound Formation, only to intercept the final segment of the Yuan Magnetic transmission. Once the text was transmitted, the entire process was fixed. Erasing the text merely erased the final Magnetic Ink and altered the Unfixed Magnetic Patterns; the other processes would not change. The Fixed Magnetic Patterns were immutable. The Magnetic Flow was the Secondary Thunder Flow, latent, fixed remnants of the Yuan Magnetic Flow within the Secondary Thunder Patterns. Thus, it was only necessary to reconstruct the Fixed Magnetic Patterns within the Letter Token. Concurrently, using Calculation, he peered into and recorded the traces left by the Magnetic Flow in the form of Secondary Thunder Patterns. With the Fixed Magnetic Patterns and the Secondary Thunder Patterns, it was possible to simulate the Unfixed Magnetic Patterns. Once the Unfixed Magnetic Patterns were determined, they could be "restored" to text using Magnetic Ink. Mo Hua nodded. This entire set of Formation logic was something he had figured out on his own. It might have some flaws, but overall there should be no significant errors. Once a Letter Token was used, it inevitably produced Magnetic Flows, leaving traces of Secondary Thunder Patterns. Such Secondary Thunder Patterns were faint and obscure, invisible to ordinary cultivators. By integrating the Heavenly Secret Calculation to amplify his Divine Sense, he could observe these hidden traces of Secondary Thunder Patterns. Currently, the only issue was actually the Fixed Magnetic Patterns... Mo Hua realized that the Fixed Magnetic Patterns in different Letter Tokens were actually different. This was something he hadn't realized before. It was after dismantling the Letter Token sent to him by Gu Changhuai that Mo Hua truly understood... Looking at the Letter Token in his hand, now split into two pieces, exposing the underlying Fixed Formation Pattern but slightly damaged due to his "crude" technique—with some cracks on the Jade Token—it was already a "battle-damaged" version of the "Letter Token," and he couldn't help but sigh... To study the Formation, Mo Hua "reluctantly" dismantled the Letter Token Uncle Gu gave him... He had three Tokens involving the Yuan Magnetic Letter Formation principle. The Taixu Token from Taixu Gate, he definitely couldn't dismantle. Even if he wanted to, he lacked the ability... The Bald Eagle's Letter Token also couldn't be dismantled for the time being. There might be secrets inside. If damaged during dismantling, the secrets would be lost. So, after much consideration, he could only dismantle the Letter Token sent by Uncle Gu. If destroyed, at most he would apologize to Uncle Gu, but there wouldn't be much loss. Through this "learning by doing" disassembly, Mo Hua truly understood some of the Formation logic inside. He also realized that if he wanted to restore the "Magnetic Patterns" to recreate the "text," the biggest obstacle at present was the Fixed Magnetic Patterns. Because Mo Hua discovered he couldn't understand the Fixed Magnetic Patterns within the Letter Token... Having learned the Fixed Magnetic Patterns in the Second Grade Sixteen Patterns, Beacon Fire Yuan Magnetic Formation by heart... But the Fixed Formation Patterns in the Letter Token were a complete mystery to him. Although similar in form to each other, the variation in details was vast. It was clear they were a type of Formation Pattern, but it was impossible to discern what precisely these specific Formation Patterns meant. This was different from the Five Elements and Eight Trigrams Formation Patterns. While variations exist in the Five Elements Bagua Formation Patterns, the basic styles were the same. It was clear what each Formation Pattern corresponded to within the Five Elements and Eight Trigrams, such as the Fire-series Formation Patterns naturally symbolizing "Fire." But the Yuan Magnetic Formation Patterns were very abstract, more like a type of "self-explanatory" or "ideographic" text. There was no clear indication of what they were exactly "symbolizing". And the functionality recorded in Jade Slips, Letter Tokens, even Taixu Tokens, was all decided by the Fixed Magnetic Patterns. Not understanding the meaning of these Fixed Magnetic Patterns, in the future, learning Yuan Magnetic type Formations would probably be limited to "imitating without true understanding."
