The new book was harder than anything it had read before.
Not impossible. Just slow. Every page had words it knew sitting next to words it did not and the ones it did not kept interrupting the flow of the ones it did, breaking the meaning into pieces that did not always fit back together cleanly. It read the same sentences multiple times, working around the unknown words the way it worked around obstacles on the forest floor, finding the meaning from the sides when the center was blocked.
By page eight it had six new words with solid matches pulled from context.
By page twelve it had ten more and the shape of what the book was about had become clear enough to read faster. Not a record or letters or someone's practical notes. Something written to explain things. The marks had the structure of something meant to be understood, built in a specific order, each page assuming the one before it had been read and absorbed.
It went back to page one and started again.
The second read was faster. The words it had pulled from context on the first pass were solid now and the sentences that had broken apart before stayed together and the meaning came through cleaner. It got to page eight in the time the first read had taken to get to page four and kept going.
Page fifteen stopped it.
Not because the language was hard. The language on page fifteen was some of the clearest in the book so far, shorter words, direct sentences, the kind of writing that was not trying to impress anyone and was just trying to say the thing it meant to say.
It was describing meridians.
Not vaguely the way the other book had described them. Actually. Where they ran through the body from the center outward, which paths came first and which developed later, what affected how they formed and what slowed their formation down. It read the page once and then read it again and then lay the book flat and turned the tongue inward and read its own body the way it had read it a hundred times before.
The speck at its center. The groove running left and slightly forward from it, worn thin and shallow but real, the surrounding tissue just slightly different from the tissue on the other side that had nothing running through it yet.
It read page fifteen a third time.
The book said meridians did not form randomly. The current moved through the body and the path it took depended on the structure it found, the density of the tissue, the way the body was built from the inside. Different bodies produced different paths. The book said this plainly, that no two cultivation paths were identical even in people following the same technique, because no two bodies were identical inside.
It read that line several times.
No two bodies identical inside.
It thought about the groove. Left and slightly forward, the direction it had chosen arbitrarily weeks ago because it needed to pick one. It had been thinking of the choice as random. The direction it picked did not matter, just that it picked one and wore the groove in consistently.
But the book was saying the direction was not arbitrary. The current had gone left and slightly forward on that first consistent night not because it had pushed it there but because that was where the body offered least resistance. The same way water found the lowest point not because it decided to go there but because the ground was already lower there.
It had not chosen the direction.
The body had.
It turned the tongue inward and read the groove again, the thin shallow channel worn into the tissue to the left and slightly forward of the speck, and then read outward from the end of it into the surrounding tissue, looking for what came next the way it looked for what came next on the road, reading the ground ahead before moving onto it.
The tissue to the left and slightly forward of where the groove ended was not identical to the tissue on the other sides. Slightly less dense. A difference small enough that it had read past it every time before without it registering as meaningful.
It was meaningful.
The body already knew where the road was supposed to go. Had known since before it started. It had just been reading the wrong thing, focusing on the groove it was building instead of the ground ahead that was waiting to be built on.
It read outward from the groove's end slowly, following the line of least resistance through the tissue the way the current followed it at night, and mapped where it went and how far it went before the difference became too small to read clearly.
Further than it had expected.
Not a complete path. Not even close. But the suggestion of one, the body's own structure pointing the way the same way the root's grain had pointed the water's way, and it was longer than one groove's worth of work and more specific than anything it could have chosen deliberately.
It closed the book and lay still while the forest moved into evening around it.
It had been building a road in the dark this whole time. Feeling ahead with each night's work, finding the next section by what the current did when it got there. Slow and uncertain and taking longer than it should have because it had not known to read the ground first.
Now it knew.
It opened the book again and read page fifteen one more time and then kept going to page sixteen and the language got harder again and it slowed back down and worked through it word by word until the light was completely gone.
That night it turned the tongue inward before starting the current work and read the full path the body was suggesting, from the speck to the end of the groove and beyond, mapping it carefully all the way to where the difference in the tissue became too faint to follow.
Then it moved the current.
Left and slightly forward, through the groove, to the end of it, and instead of stopping when it faded it followed the path the tissue was suggesting and pushed a little further and the current went, thin and weak but going, further than it had gone before, following something that had been there waiting the whole time.
It stopped when the tiredness came.
Further than last night.
Same direction.
It went to sleep.
