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

After hearing Shen Yifei's words, Ao Ying stood there stunned, unable to recover for a long time.

"What did you say? The Ninth Princess doesn't know? She doesn't know that my eldest sister's soul was used as a tonic for her?"

Ao Ying's voice changed, "Shen Yifei, what you're saying is ridiculous! She's the Immortal Emperor's daughter. Those people from the Immortal Punishment Sect were finding her tonics, how could she not know? You're not just making excuses to protect her, are you?"

"What are you talking about? Why would I protect her? She really doesn't know. I communicated with her soul in the Ten Thousand Year Cold Marrow last time. She was born weak, and the Immortal Emperor told her that she needed all kinds of rare and precious herbs to nourish her body. She obediently ate them and had no idea where those tonics came from, let alone that they were made from the souls of living people."

Ao Ying looked at him with suspicion. "Are you sure she's not pretending?"

"I'm sure." Shen Yifei nodded. "When I repaired her soul that time, her sea of ​​consciousness was completely clean, there was nothing there. That purity didn't seem fake. Moreover, you have to understand, she's been locked up in the palace since she was a child, and she's hardly ever seen any outsiders. The Immortal Emperor has raised her very well. She has no idea how treacherous people outside can be."

Ao Ying remained silent for a long while, her eyes reddening again. "Then...can she save my eldest sister?"

"Yes," Shen Yifei said decisively. "She's the daughter of the Immortal Emperor. She must have seen the runes of the Immortal Realm's restrictions and knows how to break them. As long as she's willing to help, the restriction in your eldest sister's sea of ​​consciousness shouldn't be difficult to break."

"So when did you agree to meet her next time?" Ao Ying asked urgently.

"On the night of the full moon, in the Ten Thousand Year Cold Marrow." Shen Yifei calculated the days. "Last time in the Northern Underworld, I missed the time because I was dealing with that old thing, Soul Devourer. The next full moon will be in three days."

"Three days later..." Ao Ying looked at the unconscious Ao Ling'er, gritted her teeth, and said, "Fine, then we'll wait three days. But Shen Yifei, listen to me carefully. If you dare to have any shady dealings with that Ninth Princess, or do anything to harm my eldest sister, don't blame me for turning my back on you."

Just as Shen Yifei was about to raise his finger to swear, Ao Ying picked up Ao Ling'er and ignored him, returning directly to Ao Ling'er's residence.

Actually, Shen Yifei wasn't sure either.

We didn't see Princess Zhaoxue on the last full moon night, and it's still unknown whether we'll see her this time.

After leaving Ao Ling'er's mountain peak, Shen Yifei went to find Xing He.

Xinghe saw Shen Yifei coming over and said, "Brother, you've come at the right time. I've finished preparing the medicine for Sister Hongxiu."

"How's the result?" Shen Yifei asked hurriedly.

Xinghe shook her head, her little face somewhat dejected. "No, the medicine made with your essence and blood won't work on Sister Hongxiu. Although her demonic root sensed the medicinal power, it simply couldn't absorb it."

Shen Yifei's heart sank; it really wasn't going to work.

It seems that my bloodline as a member of the demon royal family is indeed impure; I must go to the demon realm.

Shen Yifei looked at Xinghe's dejected face, reached out and rubbed her head, "Don't be so downcast, this isn't your fault. It's because my bloodline isn't pure that I dragged you down with me."

Xinghe looked up, her big eyes filled with worry. "Brother, are you really going to the Demon Realm? That's a den of dragons and tigers!"

"I have to venture into the dens of dragons and tigers. Besides, my mother is a princess of the demon race, and I have the blood of the demon royal family flowing in my veins. So, we're related in some way."

"That's hard to say," Xinghe pouted. "Not all demons are familial. What if they capture your brother and study your human-demon hybrid physique?"

"Do you think I'm some precious treasure that everyone cherishes? It's not certain who will study whom."

Xinghe was amused by his words, "Brother went to the Demon Realm and took the position of Demon King. In the future, you will be in charge of both the human and demon races."

"Little girl, you've got quite the ambition. We're going to collect essence blood, not to fight."

"Brother, you now have an ancient demon army, and the Night-Cold War God..."

"Alright, Xinghe... let's put this matter aside for now. All I want to do is restore Sister Hongxiu's demonic root; nothing else matters."

Three days is neither a long nor a short time.

Shen Yifei hadn't been idle these past few days, wandering around each mountain peak and calming the women down completely. Since his last experience with dual cultivation of spirit and soul with Ao Ying and Liu Mengli, he had found that his technique was becoming more and more refined and efficient.

Now he can replenish the soul of each woman in the time it takes to eat a meal.

The only thing that gave him a headache was Liu Mengli's bottomless pit of problems.

Over the course of three days, he replenished her soul no less than ten times, each time filling the surface of her sea of ​​consciousness, but the next day, it would be mostly empty again.

Liu Mengli wasn't in a hurry at all; on the contrary, she enjoyed it and tried different ways to get close to him every day.

After each cultivation session, she would pester him with the question, "Master, do you think my body is a little stronger today? Is my skin a little smoother?"

Three days later, at dusk, the full moon arrived as scheduled.

Shen Yifei locked himself in a secret room, set up layers of restrictions, and took out the ten-thousand-year-old cold marrow and placed it in front of him.

"Ninth Princess, Ninth Princess, you must be here," he muttered, separating a wisp of his divine soul and carefully probing into the interior of the cold marrow.

This time, he encountered no obstacles.

As soon as his soul entered the Frost Marrow, he felt a familiar aura rushing towards him.

That aura was as gentle as jade, carrying a faint ethereal quality; it was none other than the Ninth Princess, Zhao Yue.

Shen Yifei was overjoyed and hurriedly followed the scent.

Sure enough, in the open space inside the Frost Marrow, Ninth Princess Zhaoyue was sitting cross-legged on an ice crystal, her eyes closed, as if waiting for him.

She was still completely naked, and her cross-legged sitting posture instantly aroused Shen Yifei's erection.

Shen Yifei quickly composed himself, suppressed his impulse, floated in front of her, and whispered, "Ninth Princess?"

Zhao Yue slowly opened her eyes.

The moment she saw Shen Yifei, her eyes welled up with tears, and her eyes reddened.

"You...you've finally come..." Zhao Yue stood up from the ice crystals and rushed towards Shen Yifei. "I thought...I thought you would never come again..."

Her sudden movement, with its soft and gentle touch, caused Shen Yifei's heart to flutter slightly, even in his spiritual state.

"Ninth Princess, you...you don't cry, I'm here now, aren't I?" Shen Yifei reached out to push her away, but felt it would be impolite, so he let her hug him.

"Do you know how long I waited?" Zhao Yue released him, looking at him with teary eyes. "Last time on the night of the full moon, I went to bed early, eagerly waiting for you. But I waited for so long, and you didn't come! I thought there was something wrong with my cultivation technique, or maybe you didn't want to come... so I woke up, and then I couldn't fall back asleep..."
