He took the Marrow Purifier pill on his second night in the inner wing.
The previous pills had been targeted — bones, organs, a dantian primer. The Marrow Purifier was comprehensive. It hit every major bone in his body simultaneously and purified the marrow — flushing out impurities and replacing the cellular structure with something harder and more capable.
He had been warned it was painful. It was.
He bit his leather strap and trained through it. He ran laps of the inner wing courtyard while the pill worked because motion helped distribute the effect more evenly. The night guard looked at him with deep concern but said nothing — inner disciples had the right to train at night.
By the fourth hour, it was over.
Body Tempering Level Six.
He stood in the courtyard in the pre-dawn quiet and felt the difference. Level Six was a jump — he had read this, now he felt it. The body at Level Six entered the deep tempering stage. His bone density, his muscle fiber quality, his nerve response — all of it had moved to a different threshold.
He drove his fist into the stone training post. The post cracked.
He looked at his hand. Unmarked.
He stood there for a while just breathing.
Over the next week he threw himself into training with Shen Yu every morning and solo cultivation sessions every afternoon and evening. The sparring with Shen Yu was informative in exactly the way she had predicted — learning to move against qi-enhanced techniques at his level was like learning a new language under pressure.
She was good. She used her leverage style against his Question Fist and the two approaches produced genuinely unpredictable exchanges.
'You're getting faster,' she said after the sixth session. She was sitting on the floor rewrapping her wrist. 'Not just physically. Your reading speed is increasing.'
'The sessions are forcing the technique to evolve,' Wen Dao said. He was standing, reviewing the session in his mind. 'When I fought Body Tempering opponents, the reading was relatively slow — I had time to process. Against qi techniques, I have to process faster or I miss the window.'
'Pressure accelerates,' she said.',
'Everything that strengthens you requires what you'd rather avoid,' he agreed.
She looked up at him. 'You talk in principles a lot.'
'Does it bother you?'
'No. It's just unusual.' She stood. 'Most fighters talk about techniques. You talk about the reasons behind techniques.'
'The reasons are what make the techniques work,' he said.
She nodded slowly. Then: 'There's something you should know. Two inner elders — Elder Tang and Elder Shan — have been asking questions about your background. Specifically about the jade pendant and the wrist mark.'
He went still. 'How do you know that?'
'Tang is my grandfather.' She met his eyes. 'He's not a bad person. But he's practical. He wants to understand what you're carrying before someone less patient than him decides to take it.'
'And you're telling me this because?'
She hesitated. First time he had seen her hesitate.',
'Because I think you're worth keeping alive. Whoever put that technique back into practice deserves to finish it.' She picked up her things. 'If my grandfather approaches you, be honest. He responds better to honesty than tactics.'
She left.
Wen Dao stood alone in the training hall.
Information from someone close to a potentially hostile elder. Genuine? Probably. She had nothing obvious to gain from warning him falsely.
But trust was a thing built slowly and tested carefully.
He went back to his room and trained the Question Fist advanced forms until midnight.
Outside his window, in the inner courtyard, a figure stood in the dark.
He looked down at it.
Zhou Jin. Standing still. Looking at nothing in particular.
Watching.
