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

"Big sister!" Ao Ying exclaimed and rushed forward to support Ao Ling'er.

Shen Yifei quickly withdrew his divine sense and reached out to check Ao Ling'er's pulse. Fortunately, she had only fainted and was otherwise unharmed.

"What happened?" Ao Ying turned her head and glared at Shen Yifei. "Didn't you say you were just repairing the soul? How did you end up making him faint while you were repairing him?"

"Wife, don't worry." Shen Yifei wiped the sweat from his forehead. "There's a restriction deep in your eldest sister's sea of ​​consciousness, left behind by those people from the Immortal Punishment. I just tested it with the aura of the Five Elements Demon God, and it backfired on me, also affecting your eldest sister's soul."

Upon hearing Shen Yifei's words, Ao Ying's expression immediately changed. "You mean there's a restriction in my eldest sister's sea of ​​consciousness?"

"Yes, it's in the deepest part of my consciousness, under a golden light shield. I just tested it with the aura of the Five Elements Demon God, and that thing immediately retaliated."

Looking at the unconscious Ao Ling'er, Ao Ying's eyes reddened with anxiety. "What do we do now?"

"Don't rush, let me try again." Shen Yifei took a deep breath, sat cross-legged, and said, "I'll be more careful this time and see if I can figure out how to understand the restriction."

"Be careful!" Ao Ying watched nervously from the side.

Shen Yifei continued downwards and soon touched the golden light shield again.

This time, he didn't rush to make a move. Instead, he carefully controlled the wisp of divine soul wrapped in the red aura of the Five Elements Demon God, and had it circle around the golden light shield.

The surface of the light shield was shimmering with iridescent light, and some runes could be vaguely seen appearing and disappearing in the golden light.

He couldn't understand these runes at all. But he could sense the immense power contained within them. Could this be the power of the immortal realm?

Shen Yifei didn't use any force; he simply brushed lightly across the surface of the light shield.

The golden light shield emitted a very low hum, a sound that pierced through the soul and reached the depths of the sea of ​​consciousness.

Although Ao Ling'er was unconscious, her body still twitched instinctively, and she let out a muffled groan.

"Be gentle!" Ao Ying said anxiously, stamping her feet.

"I know, I know, don't rush me." Shen Yifei steadied his mind and continued to control his soul to wander on the surface of the golden light shield.

He discovered that although this light shield was domineering, it would not attack unless he confronted it head-on.

"That makes things easier." Shen Yifei felt confident and controlled his soul to slowly wander across the surface of the light barrier.

Even with such a light touch, Shen Yifei could feel how terrifying the power contained within the light shield was.

That power was unlike any power he had ever seen.

He had once heard his father, Shen Changtian, say that the power of the Immortal Realm was completely different from that of the Cultivation Realm.

Shen Yifei muttered to himself, "It is indeed much more advanced than the spiritual energy in the cultivation world. No wonder all those cultivators want to ascend."

But then he thought again, although Princess Zhaoyue's soul also possessed an ethereal quality, it lacked this oppressive aura of superiority. Her soul was gentle and refined, making people feel very comfortable.

"It seems that the immortal power used by the group of Immortal Punishment is not the same as Zhao Yue's immortal power." Shen Yifei secretly noted this difference and continued to manipulate his divine soul to wander on the surface of the light barrier.

The golden light shield seemed to sense his presence, and the golden light on its surface began to slowly rotate.

Shen Yifei felt a chill run down his spine and quickly steadied himself, daring not to make any further rash moves.

"Damn it, does this thing have a spirit?" he cursed under his breath, carefully pulling his soul away from the surface of the light barrier, leaving only a very thin thread lingering at the edge of the barrier.

The rotation speed of the golden light shield gradually slowed down, and it returned to calm.

Shen Yifei breathed a sigh of relief.

"How is it?" Ao Ying asked nervously from the side.

"It's nothing, just a test. The light shield is much more sensitive than I expected. I only used a little too much force, and it almost retaliated."

"What should we do then?" Ao Ying asked anxiously. "We can't keep my eldest sister unconscious, can we?"

"Don't worry, I'm here, there'll always be a way!"

Shen Yifei took a deep breath and once again probed his soul into the depths of Ao Ling'er's sea of ​​consciousness.

However, when he got closer, he froze.

The light shield was now emitting a faint glow, as if something was flowing inside it.

Upon closer inspection, he discovered that inside the light shield, there was something slowly rotating.

He was all too familiar with the scent of that thing.

It was that wisp of his soul that he had just transferred to Ao Ling'er!

"Damn it! All the soul I painstakingly poured in just now was sucked away by it?"

He calmed himself down and carefully sensed it.

Sure enough, all the divine soul power he transferred to Ao Ling'er was absorbed by the light shield, leaving not a trace in Ao Ling'er's sea of ​​consciousness.

All his efforts just now were for nothing.

Shen Yifei withdrew from his sea of ​​consciousness, his expression somewhat grim.

"How is it?" Ao Ying asked anxiously.

Shen Yifei wiped his face. "Wife, I have something to tell you, don't get excited."

"you say!"

"That golden light shield is just a container. All the divine soul power I just transferred to Sister Ling'er was absorbed by that light shield, leaving nothing behind."

Ao Ying's face turned deathly pale instantly. "You mean... my eldest sister..."

"Yes." Shen Yifei nodded. "I suspect that when the Immortal Punishment gang extracted your eldest sister's soul and dragon essence, it wasn't just to use her as a tonic for the Ninth Princess. They also used your eldest sister's body as a container, storing it in this restriction, and using the remaining remnant soul to nourish this restriction."

Ao Ying froze after hearing this.

After a long pause, she slowly spoke, "Then...then my eldest sister is now...isn't she just a walking corpse?"

"No, she's very strong. Even so, she can still maintain her consciousness. It's just that she's like an empty shell now." Shen Yifei sighed. "Her soul was already almost gone, and even that little bit was firmly locked deep in her sea of ​​consciousness by that restriction, used to nourish the restriction itself. All the soul power I transferred to her was absorbed by that restriction; she couldn't absorb it at all."

Ao Ying's eyes instantly reddened. "Then... what should we do?"

Shen Yifei remained silent for a moment before slowly speaking, "Wife, with my current cultivation level, I can't break that restriction."

"Then who can break it?"

"I thought of someone, only she can help me."

"Who?"

"The Ninth Princess of the Celestial Realm".

Ao Ying was stunned. "The Ninth Princess? The one... the culprit who harmed my eldest sister?"

"Yes, it's her." Shen Yifei nodded. "But this matter is a bit complicated. That restriction was set up by the people of the Celestial Punishment using methods from the Celestial Realm. Only someone equally proficient in Celestial Realm methods can break it. And the Ninth Princess is the daughter of the Celestial Emperor. She must know the ins and outs of Celestial Realm restrictions."

Ao Ying's expression shifted rapidly. "You...you have a connection with that Ninth Princess?"

Shen Yifei didn't hide anything from her, "Back in Beiming, I had a spiritual exchange with her once through the Ten Thousand Year Cold Marrow. She promised to meet me every full moon. Last time we met, I helped her replenish a part of her soul, so she owes me a favor."

"Didn't the Ninth Princess want to use my eldest sister's soul? Can she really save her?" Ao Ying didn't believe Shen Yifei's words at all.

"Wife, you have to believe me. There are some things that the Ninth Princess doesn't know at all!"
