祥瑞公主，貞觀十七年逝去，年僅二十三歲，因哮之癥，香消玉殞。病因源于皇家傳，皇后與皇帝皆患此頑疾，祥瑞不幸繼承了這不幸的產。

時流轉，千年回，祥瑞公主的命運似乎并未因時空的變遷而改變。依舊哮纏，每次發病，都有如臨深淵，氣息微弱，臉蒼白，讓人心憂。

此刻，祥瑞公主的息聲加劇，悶得幾乎無法呼吸，陳礪鋒眉頭蹙，焦急萬分。他有心尋求太醫，卻因份限制，無法渡過這一難關。他只能眼睜睜地看著祥瑞在痛苦中掙扎。

原本，若是以往，只需通知宮人，喚來太醫，祥瑞最多不過是些苦痛，未必會有生命危險。然而，此刻，看著祥瑞那拽住自己角的小手，陳礪鋒心如刀割，不忍心再讓痛苦。

眼見祥瑞病嚴重，陳礪鋒心一橫，從系統品欄中取出了一套針灸用的銀針，撕開祥瑞前的，毫不猶豫地為施針。

他的手法迅速而練，仿佛早已習慣了這樣的作。祥瑞的呼吸逐漸平穩，臉也漸漸紅潤。

陳礪鋒傾注了全部的心神，回想起過去作為老中醫時的經驗，手下的銀針如同游龍般穿梭在祥瑞的位之間。漸漸地，祥瑞的癥狀得到了控制。

就在這時，陳礪鋒突然到一陣異樣的覺，仿佛自己置于一個奇異的空間，他的變得輕盈，思維也變得清晰。

他意識到，自己似乎掌握了老中醫角的力量，雖然無法切換份，但已經能夠運用其能力。

祥瑞在清醒過來后， sees her own reflection in the silver needle and is amazed. Her chest feels unburdened, and she experiences a sense of warmth and comfort she has never felt before. She looks at the crystal-clear hand that is manipulating the needles, her eyes brimming with curiosity.

"Are you truly a god?" she whispers, her voice tinged with awe.

"Princess, I... I can't explain it," Chen Feng says, his expression puzzled. "But you're feeling better now."

Long Le squirms slightly, her cheeks flushed with embarrassment. "Yes, I am. And I feel differently... It's like I'm... lighter."

Chen Feng's heart swells with a mix of relief and happiness. He doesn't want her to die, not like this, not now. He forcefully concentrates, using the power he has gained to treat her asthma.

As he continues, Long Le's face turns beet red, her expression shifting from surprise to delight. She realizes that her chest is exposed, and she is in a vulnerable position. Yet, she cannot help but feel grateful to him. She believes he is her savior, the only person she would ever show her body to.

She silently swears in her heart, "In this life, there is no one but you, nor is there Long Le. My purity belongs to you alone."

Time passes slowly. Chen Feng finally finishes treating her. Long Le's breathing is steady, and her color is back to normal. She pulls at his hand and looks at him with a serious expression.

"Master, can you not leave?" she asks, her voice trembling slightly.

"Can't," Chen Feng responds, letting go of her hand gently. "I have things to attend to."

Long Le's eyes brim with tears. "Then, master, please stay for a night. I have made up my mind. In this life, I will serve no one but you. Master, as long as you are here, Long Le is alive. If you leave, there will be no Long Le in the world."

Chen Feng is caught off guard. This child, full of rebellion and curiosity, has made a decisive decision so early in her life. He sighs and helps her up, but his mind is made up.

"I have things to do," he says, turning to leave. "I'm sorry, Princess."

Long Le watches him go, tears streaming down her face. This is the man who saved her, the man she will never forget.

The story continues, as Chen Feng uses his newfound power to alter history. Long Le, once a fragile and vulnerable princess, finds her strength and determination. She becomes the woman she is meant to be, and her life takes an unexpected turn.

But Chen Feng knows he cannot stay. His mission in the past must be completed, and he must return to his own time.

In a flash, he is back in the present, his body shaking from the transition. He realizes that he has a choice: to stay and protect Long Le, or to return to his own world and continue his mission.

The decision is clear. He has a responsibility to his own time, and he cannot let Long Le's fate shape his own future.

With a heavy heart, Chen Feng turns to Long Le one last time. "Long Le, if we ever meet again, I will never turn you away. A man's word is his bond, and I will honor it."

And with that, he takes out the Moonlight Box, ready to leave.

As the room is illuminated by the box's light, and Long Le watches him disappear, she knows that her fate is intertwined with his. Whether or not they ever meet again, she will remember him.

---

Years pass, and Long Le, now a strong and independent woman, continues to live her life. She serves her kingdom, she finds love, and she faces trials and tribulations with grace and courage.

But deep down, she always carries a piece of Chen Feng with her, a memory that guides her through life's darkest hours.

Will they ever meet again? It is a question that remains unanswered, a mystery wrapped in time and fate.

And thus, in this alternate world, a story of love, destiny, and sacrifice continues to unfold.
