Chapter 639: Restore

"How do you 'restore' the Letter Token?"

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.
