The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

As soon as Liu Mengli said this, Hongxiu's face turned bright red all the way to the roots of her neck, and she wished she could disappear into the ground.

Shen Yifei was also taken aback. He looked at Hongxiu, then at Liu Mengli, and asked, "What do you mean by that? Do you mean I need to merge with her to refine the essence blood?"

Liu Mengli blinked her peach blossom eyes, "Master, refining essence blood isn't as simple as you sitting there and having Hongxiu massage your shoulders. For the Xuanpin bloodline to refine essence blood, it requires the Xuanpin Qi within her body to merge with your essence blood. Only then can the impurities in the essence blood be completely purified, forcing out the purest power. And the Xuanpin Qi is hidden deep within her dantian..."

Liu Mengli looked at Shen Yifei with ill intent, "Master, you don't need to worry. With your talent, you've got more than enough."

Shen Yifei quickly interrupted her, "Does refining essence blood have to be so complicated?"

Then he turned to Hongxiu, "Sister Hongxiu, what Mengli said..."

Hongxiu lowered her head, "She...she's right!"

"Then why didn't you say so sooner?"

"Young Master...this servant..." Hongxiu's voice trailed off, "This servant is afraid you'll think I'm unworthy..."

Shen Yifei sighed, "What do you mean by 'worthy' or 'unworthy'? Don't call me a servant anymore. You are my Hongxiu! As long as you're willing, from now on you'll be my woman, Shen Yifei's woman!"

Hongxiu slowly raised her head. "Young Master... this servant is willing. From the first moment I saw you, my heart... I..."

"Alright, let's prepare the medicine first. Let's go find Xinghe."

The two entered the cauldron and found Xinghe, who was holding the phoenix tail feather in her hand and muttering something to herself.

Hearing footsteps, Xinghe looked up and saw Shen Yifei and Hongxiu. "Brother! You're here!"

Shen Yifei looked at her small face; after not seeing her for a few days, he felt something was off. He frowned but didn't say anything.

Seeing that he didn't say anything, Xinghe tilted her head and asked, "Brother, what are you daydreaming about?"

Shen Yifei snapped out of his daze and gave her a careful look.

Xinghe is still the same Xinghe, petite in stature, with her hair tied in two buns, looking like a little porcelain doll.

But Shen Yifei felt that there was a change in her eyes and brows, but he couldn't quite put his finger on what was different from before.

"Xinghe, have you been feeling unwell lately?"

Xinghe blinked her big eyes: "No, I can eat and sleep well, I'm full of energy. Brother, what's wrong? Why are you suddenly asking me this?"

"It's nothing, it's just that your complexion looks a little different."

Xinghe touched her face: "Really? Did I stay up all night preparing medicine and get these dark circles under my eyes?"

Shen Yifei didn't say anything, but he was inwardly puzzled.

He remembered Liu Mengli saying that the Life Demon God Lingyun was a little girl who would never grow up and was always chasing after Wan Shuo.

Is it because of that sentence that I feel differently when I look at Xinghe?

Just like back then, when he doubted that Xinghe was an immortal doctor.

As time went on, Xinghe didn't seem to have anything special about her, and that thought gradually faded away.

Shen Yifei explained his purpose to Xinghe, and specifically mentioned Hongxiu's special physique.

"The Xuanpin lineage, the mother of all bloodlines, can refine the essence of any bloodline..." Xinghe muttered as she looked at the Demon Emperor's essence blood. "Brother, you're right. If Sister Hongxiu's physique can really be brought into play, it's more precious than any rare and precious treasure."

Shen Yifei and Hongxiu listened to Xinghe's whispering from the side.

"I have the phoenix tail feathers, the ten-thousand-year-old cold marrow, and the essence blood of the demon royal family... Brothers, you go out and wait for me. It will take a day to prepare the medicine."

After leaving Xinghe's residence, Shen Yifei went directly to Liu Mengli's place.

Liu Mengli was lounging on the couch, feeling utterly bored.

Seeing Shen Yifei enter, her peach blossom eyes immediately curved into a smile: "Master, you missed me? Want to try your luck with me first?"

Shen Yifei laughed and scolded, "Test you my foot! I wanted to ask you, isn't Xinghe acting a little strange?"

Upon hearing this, Liu Mengli immediately perked up, sat up from the couch, and stared intently at Shen Yifei with her peach blossom eyes: "Master, do you also think there's something wrong with her?"

Shen Yifei nodded: "Did you discover something?"

"Master, don't you think Xinghe looks a bit like Lingyun?"

"Yes, I always felt there was a slight resemblance."

Liu Mengli chuckled and said, "Master, I'm quite familiar with Lingyun. That girl has a very special aura about her, similar to the scent of wood. I really couldn't smell it on Xinghe."

Shen Yifei frowned: "Could it be that the aura disappeared after the spirit was reincarnated?"

"It's hard to say." Liu Mengli shook her head. "Reincarnation is a very unpredictable thing. But if Lingyun really wants to reincarnate, she can't possibly leave no trace. As long as there's even the slightest trace, I'll be able to tell."

"Mengli, take a closer look at her again," Shen Yifei said solemnly. "Use your power of reincarnation to examine her soul and see if there's anything hidden."

Liu Mengli pouted: "Master, are you making me do chores?"

"Yes, I can offer my labor as payment."

"What kind of labor are you talking about?"

"You know what I mean."

Liu Mengli's peach blossom eyes immediately curved into crescent moons: "Okay, then I'll go take a look."

The two quietly arrived at Xinghe's residence. Xinghe was squatting on the ground arranging a pile of medicinal herbs, humming a little tune. Her two little pigtails swayed with her movements, making her look both well-behaved and adorable.

Liu Mengli did not disturb her. Instead, she hovered in mid-air and silently activated the power of reincarnation. A faint ray of light emanated from between her brows and silently reached out towards Xinghe.

Shen Yifei stood to the side, not daring to breathe.

After a while, Liu Mengli withdrew her gaze, her brows furrowing slightly.

"How is it?" Shen Yifei asked quickly.

"That's strange." Liu Mengli frowned. "Her soul is completely clean. There's no trace of reincarnation or the mark of a remnant soul. She's just an ordinary little girl, except her soul is a bit more solid than the average person's, and it looks like she's cultivated some kind of technique."

Shen Yifei was somewhat disappointed: "You mean, she has nothing to do with Lingyun?"

"I can only say that what I saw was not it," Liu Mengli shrugged. "Master, perhaps you're overthinking it. There are plenty of people in this world who look alike; we can't possibly make them all reincarnations of demon gods, can we?"

Shen Yifei sighed and nodded.

Maybe I'm just overthinking things.

If Xinghe is truly the essence of the Life Demon God, then no one can match my luck.

He managed to encounter a Five Elements Demon God successor who inherited Wan Shuo's legacy, a reincarnated Reincarnation Demon God, and a girl who was suspected to be the Life Demon God.

He turned to leave, but Xinghe suddenly turned back and gave him a sweet smile: "Brother, were you secretly watching me just now?"
