The moment the last sentence was finished, the writing on the letter flashed faintly and vanished completely.
The sheet of paper split apart, crumbling into a small handful of scraps that slipped through his fingers.
Clearly, this thing was single-use. It should prevent any chance of it being noticed by outsiders.
Lu Yuan looked at the scraps in his palm and raised an eyebrow. Could Mo Shui receive it? He was not sure either, but he hoped so.
Ah, but for future letters, he would have to find another way. He could not write anything too strange.
He gathered the scraps and set them aside, then spread out the paper and pen he had asked for. This letter was written in Imperial Language.
"Dear Karl: I received your letter. I will keep an eye out for the materials. Thank you, and thank the mayor for me as well. Congratulations on mastering the Song of the Sandworm. Even if it is an abridged version, it is still impressive—at least far better than I am now. Lately, with so much going on in Bronze City, I have made almost no progress in Ancient Music Theory. Next time, I think your Ancient Music Theory may even surpass mine. Also, when you go out to sea with your grandfather, make sure to listen and observe more. Never try to be a hero. I have made a note of going back. Once I finish up here, when I pass through Sandworm Town, I will definitely ask the mayor for a bowl of hot soup. —Lu Yuan"
After finishing the letter, Lu Yuan learned of a merchant caravan heading west and asked them to carry it with them. The caravan leader accepted several Copper Shields and thumped his chest, guaranteeing that it would be delivered.
