The clay vessels were okay.
Not great. Just okay. Ren had spent three nights figuring this out by doing what he usually does when he wants to know something: he got rid of what he hoped was true and worked with what was left.
He had hoped the vessels were good. They were three of the pieces from the storage yard and they were still in one piece when everything around them was broken. The inside of the vessels had a glaze on them, which meant they had been used with something hot before. Someone had used them. Then just left them behind which was the kind of thing Ren had learned not to wonder about and just be happy about.
Okay meant: the vessels could hold a flame without breaking they could keep the inside pressure right. They could be cleaned well enough that they would not mess up his work with leftover stuff.
He had cleaned the vessels over four nights.
Three hours each night for the three nights. Forty minutes on the night which told him that the vessels were clean. When it took a lot time to make sure they were clean that meant they were really clean.
He had tested one vessel with water and a small heat source. A piece of spirit stone that he had found. The vessel worked fine. No cracks when it got hot. No leaks.
Okay.
He would use it.

The herb problem was harder.
He did not have any herbs.
This was not entirely true. He had some herb leftovers. The dried-up stuff that alchemists threw away after they were done with it. He had found two places where this stuff ended up: a compost pile near the gate and a bin outside a storage building. He had been collecting this stuff for six weeks.
What he had was not good enough to use. The leftover herb bits only had a bit of the good stuff left in them.. Ren thought that even a little bit of something was better than nothing.
The question was whether he could make this leftover stuff work or not.
He did not know the answer.
So he was going to find out.
--- ◆ ---
He waited until it was really late.
Everyone in the sect was sleeping. The disciples who took care of the water would wake up soon.. For now it was quiet. The formation array was not as sensitive as it was during the day.
Ren had checked this a weeks ago. The array took longer to respond at night. He had. Seen that it took around twelve to seventeen minutes for someone to come after a cultivation event at night. He did not need that time.
--- ◆ ---
The training hall was different at night.
It was the place but it felt quieter. The beam was still cracked the swords were still dull. The floor was still worn out.. It felt like the place was empty in a way that felt right.
He brought the vessels his notebook, the herb leftovers and the spirit stone. He also brought a water skin with a solution in it. Not water, but a weak salt solution that he had made himself.
He set everything up in the corner of the room. Sat down.
He thought about what he was going to do one time.
--- ◆ ---
The idea of secondary extraction was simple.
The leftover herb bits still had some of the stuff in them but it was stuck to the plant bits. The usual way of extracting the stuff used heat to break the plant bits apart.. Ren was going to try something else: breaking the plant bits apart slowly and using a small amount of heat to get the good stuff out.
This way he might get less of the stuff but what he got would be better.
He had learned this from reading books. Three alchemy books and one chemistry book. The alchemy books told him what worked and the chemistry book told him why.
He used his Qi to make the spirit stone warm up. Not hot, just a little warm.
The stone worked.
He put the vessel over it and started.
--- ◆ ---
The first two tries taught him some things he did not know.
The first try taught him that the herb bits from the compost pile were no good. They had gotten wet. Were ruined.
The second try taught him that the salt solution was too strong. It was messing up the stuff instead of helping it.
He fixed the solution. Tried again.
It worked.
After two hours he had an amount of the good stuff in the vessel. A little bit of pale liquid that was a little thick and had a special smell.
He looked at it.
Then he looked at his hands.
He was fifteen years old in the sect at three in the morning sitting on a stone floor with a little bit of bad cultivation liquid that he had made from leftover herb bits using old clay vessels and a broken spirit stone.
It was not great.
He made a note in his notebook.
--- ◆ ---
He did not try the liquid on himself.
He had decided not to do this before he started. He still did not want to. The liquid might have stuff in it and he did not want to get hurt.
He stored the liquid in a packet and labeled it.
Then he cleaned the vessels well.
By the time he was done it was almost time for the water disciples to wake up.
He packed everything away. Went back, to his dorm.
--- ◆ ---
He could not sleep.
Ren sat on his mat in the dark. Wrote down the session in full. He did not use the notes he used for quick observations. He used the form he used for things that needed to be understood. What had. What had worked. What he had thought would happen that actually did happen. What he had thought would happen that did not happen. What the difference between those two things said about his understanding of the process.
The model needed to be updated. The problem with the concentration showed that he did not fully understand how the suspension medium behaved when it was exposed to Qi. The references talked about the techniques requirements in terms of cultivation input than chemical ratios. This meant they assumed the reader already understood the underlying chemistry. Ren partially understood it.. Not completely.
He added three books to his reading list. Then he added a book, which was not about alchemy but about how Qi-interaction compounds broke down under different thermal profiles. This was a materials science question than a cultivation question.. The two areas were related and Ren had learned that related areas usually had something useful to say to each other if you were willing to look at both.
He closed the notebook. Outside the water duty bell rang. People were getting water. Feet were walking on stone. The outer sect was starting its day as it always did loudly and without ceremony.
Ren put the notebook under his mat. Stood up. He had forty minutes before the official training session started. He went to find Wei Shan.
Wei Shan was already in his corner. He was always in his corner before the formal session started. Ren thought this was either a habit or a preference for occupying space before others did. Both were possible for someone who had watched the sects rhythms for nine years.
Wei Shan was drinking tea. He was always drinking tea at this hour. Ren thought the tea might be something to do when someone approached, which meant the approach required acknowledging him.
"The moisture contamination threshold for processed herb residue " Ren said, sitting down across from him. "What causes the contamination to survive the heat stage instead of burning off?"
Wei Shan looked at him over his cup. He paused for a moment. "If the herb residue is exposed to humidity for longer than three days it changes the cellular binding structure " he said. "After that the moisture is not on the surface. It is part of the structure. The heat that would remove it would also damage the herb residue."
"The references do not explain it that way " Ren said.
"The references are written for people who already work in storage " Wei Shan said. "Why are you asking about herb residue processing?"
"I am asking about moisture contamination thresholds " Ren said.
Wei Shan was quiet for a moment. "There is a rack of herb curing jars in the inner supply closet " he said. "They create a low-humidity environment that extends storage from three days to three weeks."
Ren thought about this. Darius had the key to the inner supply closet.
"Thank you " he said.
"Do not thank me " Wei Shan said. "I answered a question. That is not a favor."
Ren thought about this for a moment. "You make a distinction between favors and information " he said.
"Favors create obligations " Wei Shan said. "Answering questions creates knowledge. Those are things and I prefer to keep them different."
This was the direct thing Wei Shan had said to him in two weeks. Not personal,. A statement of principle.
Ren filed it away. Wei Shan was a man who distinguished between obligation and information. He had knowledge he shared in pieces. He had been waiting nine years for something to finish. Had decided to share useful knowledge without creating obligations.
The training session started at the hour. Ren trained. The Energy Paths first channel was at the edge of its saturation threshold. He could feel it the sense of a vessel that had been filling steadily and was now noting its state.
He held the compression steady. He was not going to rush it.
Across the hall Shen Yue arrived at the hour. She set her mat in the position she had been using since their conversation. It gave her a sightline to the training floor without positioning herself in direct relation to him.
They did not speak during training sessions. This had not been agreed upon. It had simply emerged as the practice of two people who were not yet at the stage where speaking during sessions would be more useful than not speaking.
He noted that she was further into Foundation Establishment than her outer sect presentation suggested. He had been updating this estimate as her training patterns gave him data. Today she was running a circulation sequence he recognized from one of the sects standard Foundation manuals.
He did not note this aloud. She knew he had noticed. He suspected she had allowed him to notice. Two people operating with logic tended to read each others exposure of information for what it was: an offer.
He would respond to the offer when the time was right. That was the foundation. Everything else came after the foundation.
That afternoon he found Darius near the storage yard gap. "I need to use the herb curing jars in the inner supply closet " Ren said. "I need two hours with them time you have the key."
Darius did not ask why. He had stopped asking why after the formation stone inventory. "Tomorrow morning " he said. "Holt does his rounds on Tuesdays, which means the maintenance building is clear from the second to the fifth hour."
"I need the second and third hours " Ren said.
"Done " Darius said. "The jars have a sealing mechanism. You press the side down while turning the right quarter-rotation. Otherwise you break the seal."
Ren noted this. "How do you know the mechanism?" he asked.
"I have opened them before " Darius said. "Out of curiosity. They still had material inside from years ago. Completely. Still sealed perfectly." He paused. "Whatever the previous formation elder was storing he took his preservation methods seriously."
Ren was quiet for a moment. Sealed jars. A formation elder who had retired than left or died. Herb curing equipment stored than discarded. A maintenance supervisors key that a merchant familys son had access to for reasons Darius had never explained.
There was something in this room that he did not yet have pieces to understand. He added it to the list.
" third hour tomorrow " he confirmed.
"I will be at the gap at the second-hour bell " Darius said. Then with a directness: "You are very specific about what you need and very quiet about what you are doing with it."
"Yes " Ren said.
"That is either very intelligent or very suspicious."
"It is both " Ren said. "They are not mutually exclusive."
Darius considered this. "Fair " he said.. Walked away.
That night the Energy Paths first channel reached its threshold. Not dramatically. Not with the pressure that cultivation manuals described for standard breakthrough events. A threshold, in his compression method felt different. It felt like a door closing. The channel had been accepting density for months. Now it stopped accepting and simply held, perfectly and completely what it had accumulated.
The change happened inside him. You could not see it from the outside. He was sitting on his mat in the room in Block C when it happened. His family was sleeping around him in the dark. He sat there for a moment before he did anything.
He thought about what this change meant.
The first channel took a time to open because he did not do it the usual way. He built it from the bottom up. Filled it slowly. This way the channel could get used to what it was getting. The result was a channel that was stronger than it should be at this point. It could hold more than a channel. He did this on purpose.
This channel would not show up correctly on any test.
He did not write this down. He did not need to. He would remember this moment clearly. Moments, like this stay with you in a way.
He lay down to sleep.
The second channel was already there waiting for him. He could feel where it was, like you feel the shape of a room when it is dark. You do not see it. You know where it is.
He would start working on the channel tomorrow.
Tonight he went to sleep. The disciples who took care of the water woke up the rest of the world without him. In the part of the compound eleven special stones were absorbing the energy of the air. This was happening quietly. Nobody knew about it.
