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

Shen Yifei stiffened at the question, but luckily he was thick-skinned and quickly put on a smile: "Xinghe, I just happened to be passing by with Mengli and I stopped by to see you. How's the pill refining going?"

Xinghe tilted her head, her big eyes full of disbelief: "Brother, you're lying. Sister Mengli just... just now she circled around in my consciousness several times."

Liu Mengli, exposed to his true colors, remained unfazed and laughed, "Sister Xinghe, what are you saying? I was just curious about you. You're so young, how come your medicine-preparing skills are more refined than those old alchemists who have lived for hundreds of years? I just want to see what's going on in your little head."

"That's a natural talent!" Xinghe puffed out her chest, looking smug.

Shen Yifei found it amusing to see Xinghe acting so smugly, even mimicking his speech.

Looking at them, they don't resemble the Nine Great Demon Gods at all.

Xinghe waved her little hand, "Don't delay me from preparing the medicine. Brother, bring Sister Hongxiu over first thing tomorrow morning."

Shen Yifei, feeling humiliated after being chased away by Xinghe, yelled into the house, "You little brat, you're getting more and more disrespectful! You even dare to chase your brother away!"

From inside came Xinghe's clear voice: "Brother, if you keep bothering me while I'm preparing the medicine, and I get distracted and make a mistake with one of the ingredients, Sister Hongxiu's demonic root will be ruined! Think about it!"

Upon hearing this, Shen Yifei grabbed Liu Mengli and ran away.

The next morning, just as dawn was breaking, Shen Yifei brought Hongxiu to Xinghe's residence.

Xinghe was squatting in the courtyard, with a small alchemy furnace in front of her. The fire in the furnace had been extinguished, but wisps of steam were still rising from the lid.

She heard footsteps, looked up, saw Shen Yifei and Hongxiu, and yawned widely.

"You're here? Come in." Xinghe stood up and opened the lid of the alchemy furnace.

A rich medicinal aroma wafted from the furnace. Shen Yifei leaned closer and saw a pill at the bottom of the furnace.

The pills were red, yellow, and blue, with a layer of pale gold patterns flowing across their surface, making them look quite peculiar.

Xinghe took the pill out of the furnace and placed it in a jade dish. "The main ingredient is phoenix tail feather, the medicinal properties are neutralized by ten-thousand-year-old cold marrow, and the essence blood of the Demon Emperor that you gave me is used as a catalyst. I added some auxiliary ingredients and simmered it all night. The heat is just right. Sister Hongxiu, please eat this."

Hongxiu looked at the pill, her lips trembling slightly, and for a moment she didn't dare to reach out and take it.

She had been waiting for this day for hundreds of years.

Back then, the Demon King, who was under the control of the Bewitching Heart, personally destroyed her demonic roots, turning her from a demon princess's maid into a useless person who was even worse than an ordinary person.

She wandered into human territory and lived in fear for so many years that she had long forgotten that she still had the blood of the Xuanpin lineage flowing in her veins.

"Sister Hongxiu?" Shen Yifei called out softly when he saw her in a daze.

Hongxiu snapped out of her daze, her eyes already red. She took the pill, tilted her head back, and swallowed it in one gulp.

The moment the pill entered her stomach, Hongxiu trembled violently, and a scorching aura burst forth from her dantian, spreading wildly along her meridians.

"Hiss..." She gasped, and fine beads of sweat appeared on her forehead.

"Sister Hongxiu, how are you feeling?" Shen Yifei quickly helped her up.

"Hot...so hot..." Hongxiu frowned deeply. "It feels like...like something is growing in my dantian...Ah...it hurts...it hurts so much!"

Hongxiu clutched her lower abdomen, bending over in pain.

Xinghe stared at Hongxiu's face, and her relaxed expression suddenly turned serious.

She reached out and grabbed Hongxiu's wrist, examined it carefully, and her expression changed slightly.

"Oh no, the medicine is too potent. Her demonic root has been destroyed for too long, and her meridians have severely atrophied. The medicine can't penetrate her all at once, and it's backfiring!"

Shen Yifei panicked: "What should we do then?"

Xinghe flipped her small hand and took out three silver needles, which she swiftly inserted into three major acupoints on Hongxiu's lower abdomen, chest, and brow.

"Brother, transfer a wisp of the Five Elements energy to Sister Hongxiu to protect her heart meridian! Leave the rest to me!"

Shen Yifei dared not delay, transforming the power of the five elements within his body into a gentle warm current, which flowed into Hongxiu's back.

As soon as the warm current entered Hongxiu's meridians, it immediately became a pioneer, traveling along Hongxiu's meridians.

Hongxiu's body trembled violently, and Shen Yifei could feel her meridians expanding inch by inch.

"Hold on! Hold on!" Shen Yifei encouraged Hongxiu while giving her breathing exercises. "Sister Hongxiu, you've endured so many years, now is the most crucial moment, you must hold on!"

Hongxiu gritted her teeth, feeling like she was about to explode, but she managed to hold back without uttering a sound.

After about the time it takes to drink a cup of tea, a faint light suddenly appeared in Hongxiu's dantian.

The light was initially only the size of a soybean, but as the medicinal power continued to flow in, it became brighter and brighter, eventually transforming into a fist-sized black ball of light that slowly rotated in the dantian.

"It's done!" Xinghe shouted excitedly, "The Demon Root has grown back!"

Before she could finish speaking, Hongxiu's body trembled violently, and a powerful aura erupted from within her. That aura carried the domineering and wild nature unique to the demon race, whipping up a gust of wind.

Shen Yifei was forced back two steps by this aura and couldn't help but exclaim in surprise, "Early stage of Tribulation Transcending!"

Hongxiu slowly opened her eyes and looked down at her hands. Her hands were fair and slender, just as they had been before.

But she could feel that long-lost power within her body surging and flowing through her meridians.

"My... my demonic root has recovered? My cultivation level...?"

Xinghe said smugly, "Phoenix tail feathers, ten-thousand-year-old cold marrow, plus the essence blood of the demon royal family—these three are indispensable. If the medicinal power were even slightly stronger, you would have been overwhelmed. Fortunately, I controlled it precisely, not a bit more or less."

Tears welled up in Hongxiu's eyes. She knelt on the ground with a thud and kowtowed three times to Xinghe, saying, "Miss Xinghe, I will never forget your immense kindness in this lifetime!"

Xinghe was startled by her kneeling and quickly stepped aside, her two little pigtails trembling: "Oh dear, Sister Hongxiu, please get up! What are you doing? I can't accept this!"

Shen Yifei stepped forward and helped Hongxiu up, wiping away her tears: "Alright, Hongxiu, don't cry. Xinghe is family, why are you being so polite with her? If you really want to thank her, just buy her more candied hawthorns in the future."

Xinghe's eyes lit up: "Sister Hongxiu, I really want to eat candied hawthorns!"

Hongxiu was amused by the two of them chatting back and forth, and she stopped crying and started laughing.

Seeing that Hongxiu's emotions had stabilized, Xinghe said, "Sister Hongxiu, although your demonic root has recovered, it has been crippled for so many years, and your foundation is still unstable. Don't rush to cultivate these next few days; insist on taking a medicinal bath for an hour every day."

Hongxiu nodded quickly: "I will follow Miss Xinghe's orders."

Xinghe turned to look at Shen Yifei, blinking her big eyes: "Brother, Sister Hongxiu's demonic root has just recovered. Don't even think about refining her essence blood. Her body is too weak; you might explode."
