Three days after discovering the method of transformation, Zhì Yuǎn and Yù Qíng had already perfected the cycle. In the mornings, he transferred Yang to her; she transformed it into Yin and returned it. In the evenings, she transferred Yin to him; he transformed it into Yang and returned it. The flow was constant, smooth, and each day their receptacles filled a little more.
But something bothered him.
The Wisdom in his mind, which now manifested as a sense of measure, told him that this was only the surface. As if they were drinking from a stream when an ocean lay just beyond, invisible.
What was missing?
The answer came during lunch at the Yù house at the end of the week.
Sū Huì, his mother-in-law, served the soup with a smile that seemed to carry more meaning than the words that accompanied it.
"You two have been looking different," she said, sitting at the table. "More… radiant."
Yù Qíng lowered her eyes to her bowl, the tips of her ears turning red.
"It's the sun," she murmured.
"The sun, of course." Sū Huì laughed, a low, knowing laugh. "But it's not only the sun that makes a wife glow, my daughter."
Yù Chéng coughed, clearly uncomfortable, and changed the subject with the skill of a man who had spent decades with a woman who spoke her mind. But the seed had been planted.
On the way back through the bamboo grove, Yù Qíng walked in silence, her fingers interlaced with his. When they reached the house, she finally spoke.
"My mother noticed."
"Noticed what?"
"That we are… different." She turned to face him, her eyes shining with something he could not name. "She doesn't know about cultivation. But she knows there is something between us. Something stronger than before."
He pulled her inside, closed the bamboo door, and pressed her against the wall.
"Your mother is right," he said, his lips close to hers. "There is something stronger."
The kiss that followed was different from earlier ones. There was an intention in it he had not expressed before: not merely desire, not merely affection. It was experimentation. It was cultivation.
She must have felt the difference, because her fingers dug into his shoulders and her body arched against him before he even carried her to the bedroom.

What happened that afternoon was a revelation.
When their bodies joined, Zhì Yuǎn felt the Yang inside him not merely flow, but explode. It was not the controlled trickle he transferred during the day. It was a torrent, a flood, a river breaking through a dam.
And her Yin, which he always received as a gentle coolness, now struck him like a tide rising against a cliff. Strong. Deep. Inescapable.
He lost track of time. For minutes—or perhaps hours—there was only the rhythm, the exchange, the circuit that closed and reopened with each pulse. When he finally collapsed on her, breathless, feeling his heart pound like a runaway drum, the Wisdom in his mind had already made its calculations.
Fifty times more potent, he thought, dazed. Perhaps more.
Beside him, Yù Qíng breathed in gasps, her hair spread across the pillow, her face still flushed.
"What…" she tried to say, but her voice failed. She coughed, tried again. "What was that?"
"That," he answered, still dizzy, "is what we were missing."
She turned toward him, her eyes still glazed.
"Then why don't we do it all the time?"
He laughed, a weak, almost pained laugh.
"Because we can't."
"Why not?"
"Because that—" he touched her chest, where her heart still beat fast, "costs something. My body is exhausted. Yours is too. We are mortals, Yù Qíng. Our bodies were not made to endure that for long."
She frowned, and he saw the frustration in her eyes—the same frustration she had felt trying to absorb the sun in those first days.
"Then we have to get stronger," she said. "To last longer."
"Yes." He lay on his back, staring at the bamboo ceiling. "But how?"
---
The next morning, he walked alone through the bamboo grove.
He needed to think. The Wisdom in his mind worked without cease, processing information, comparing patterns, suggesting paths. But something was missing. A piece. An ingredient.
The Qi of the world is sparse. The Qi we exchange is potent, but our bodies are fragile. We need something that strengthens the body without relying on cultivation. Something that increases stamina, the flow of blood, the capacity to sustain the rhythm.
His feet led him to the deepest part of the grove, where the stalks grew densest and the sun barely penetrated. There, the air was damp and cool, and Yin accumulated like water at the bottom of a valley.
That was when he saw it.
Between two stalks of black bamboo—the darkest he had ever found, so black they seemed to absorb light—a flower was blooming.
It was small, the size of his thumb, but its color was impossible to ignore: a red so intense it seemed to glow in the twilight, like an ember that refused to go out. Its petals were thin as rice paper, translucent at the edges, and at its center was a golden stamen pulsing with a faint light.
Zhì Yuǎn knelt before the flower and activated his inner vision.
What he saw made him hold his breath.
The flower did not contain ordinary Qi. It contained condensed Yang, so pure that his meridians vibrated just from being near it. But how? In a place of such deep Yin, how could something so Yang arise?
The answer came in a flash of understanding: the Yin there was so strong it had inverted. Like the transformation he had learned to perform with Qi, the environment itself, under extreme pressure, had generated its opposite. At the heart of darkness, a spark of light.
He picked the flower carefully, feeling its warmth against his fingers. He brought it to his lips and ate it.
The taste was strange—sweet at first, then bitter, then hot. The heat spread through his throat, down into his chest, and then…
His heart raced. Not in alarm, but as if someone had stoked a fire that had been burning weakly. Blood ran faster through his veins, his muscles filled with an energy that was not Qi, but something more primal: vigor.
He remained still for a long moment, feeling the flower work inside him. When the heat finally stabilized, his breathing was deeper, his limbs lighter, and there was in his chest a sense of fullness he had never experienced.
The heart, he understood. The flower nourished the heart. Increased the flow of blood. The body grows stronger, more resilient.
He stood and looked around. Were there other flowers? He searched among the black bamboos, but found only that one. Perhaps they grew only once a season. Perhaps they were rare. But it did not matter. He had what he needed.
---
That night, he said nothing to Yù Qíng about the flower. He simply came to her as never before.
She felt the difference immediately. His touch was firmer, his breathing more controlled, his rhythm more sustained. When they joined, the Yang that flowed from him was not an uncontrolled torrent, but a steady river, powerful, inexhaustible.
She arched her back, her fingers digging into his back, and the Yin she returned was equally strong, equally steady. The circuit closed, and for the first time it did not break after a few minutes.
They lasted. And lasted. And lasted.
When they finally parted, sweat covered their bodies and both breathed heavily, but there was no exhaustion. Only satisfaction. Only fullness.
"What changed?" she asked, her voice trembling. "You're different. Stronger. More… enduring."
He touched his chest, where his heart still beat in a calm, powerful rhythm.
"I found a flower. In the bamboo grove, in the darkest part. It nourished my heart. Increased the flow of blood."
"And that allows…"
"It allows me to sustain the rhythm longer. And to transfer more Yang to you."
She looked at him for a moment, and then her eyes widened.
"So if I find one too…"
"You will also last longer. And transfer more Yin to me."
She smiled, and the smile was that of someone who had just found the key to a treasure.
"Where is this dark part?"
---
In the days that followed, Zhì Yuǎn noticed that his cultivation had advanced.
Not only had the Qi in his receptacle increased—that was expected. But his meridians, which he had expanded and consolidated repeatedly, now seemed to have reached a new level. The flow was smoother, broader, more resilient. As if the flower had strengthened not only his heart, but the very walls of the channels through which Qi coursed.
Second stage, he named in his mind. Intermediate.
The Wisdom then showed him a pattern. Four levels in each stage. Initial, intermediate, peak, maximum. He was at the second. Yù Qíng was still at the first, but approaching quickly.
There will be more flowers, he thought. Or other resources. The world may be sparse, but it is not empty. We only need to know where to look.
That night, while Yù Qíng slept with her hand on his chest, he closed his eyes and plunged into his inner vision. One thousand two hundred and forty-three points. Three hundred and forty already absorbed. The receptacle still had room, but the meridians had already expanded twice. At the current rate, in a few weeks he would reach the peak.
And then, the next realm.
He did not know what it was called. Did not know what would come after. But he knew he would not be alone.
Yù Qíng murmured something in her sleep and pressed her hand against his chest. He smiled in the dark.
Together, he thought. Always together.
