The night was as dark as ink, deep and serene.

The moon hung high in the sky, casting its cool light that illuminated the outline of the room.

In the very center of the soft, large bed, a small figure sat cross-legged as if meditating.

A faint light emanated from her, like twinkling stars in the night sky, scattering a soft glow.

In a short while, the originally petite figure gradually grew larger.

As she grew, a stunningly beautiful face was revealed under the soft glow of the light.

The glow faded.

Hang Suisui withdrew her spiritual power, opened her eyes, and looked at the moonlight outside the window.

With a pinch of her fingertips, a thin little paper figure appeared in her hand. Hang Suisui shook the little paper figure in her hand, making a few rustling sounds.

She got out of bed and threw the paper doll on the ground. The moment the paper doll landed, it transformed into a little girl who looked exactly like Hang Suisui when she was a child.

The little girl stared blankly ahead, her eyes unfocused.

Hang Suisui shook the bell bracelet on her wrist, and the silver bell, which had never rung before, made a clear sound.

She extended her fingertip, touched a small bell on the bracelet, and then touched the little girl's forehead.

The little girl seemed to come alive instantly, her eyes suddenly sparkling with life.

Upon seeing Hang Suisui, he immediately rushed forward joyfully, opening his arms to hug Hang Suisui's leg.

"Sister, sister, sister, you've finally let me out!"

Her clear, childlike voice was exactly the same as Hang Suisui's.

Hang Suisui looked at the little girl who was happily rushing towards her, quickly stretched out her index finger and pressed it against the little girl's forehead, stopping her from rushing over to hug her.

"You stay here and wait for me to come back. Don't get it wet."

After speaking, Hang Suisui watched as the little girl's two plump, white arms, like lotus roots, flapped wildly in the air.

That's why they're so dishonest.

After thinking about it, I cast a water-repelling spell on it, just in case.

With a flick of his wrist, an invisible gust of wind tossed Hang Suisui No. 2 onto the bed.

Hang Suisui pointed at the number two warning officer who was trying to get up and said, "Go to sleep."

Upon seeing Hang Suisui's attitude, the little girl quickly lay back down on the bed and even pulled the blanket over herself.

She looked like a well-behaved baby, her big eyes blinking as she looked at Hang Suisui.

"I'm going to sleep. I'll wait for you to come back."

Hang Suisui nodded, turned around, and disappeared into the room as a streak of light.

There was no one for a hundred miles, and no smoke for a thousand miles.

A tall building with a deep courtyard, brightly lit.

In the tranquil library, the air is filled with the faint scent of ink and books, and the bookshelves are neatly arranged with rows of heavy books.

The sound of footsteps was swallowed up by the soft carpet.

The friction between the paper and fingers, accompanied by subtle sounds as it is turned.

By the light of the lamp, Jinqian stepped forward with the booklet in her hands, bent down and handed it to the person in front of her on the table.

Looking up, I was startled to see the page of the book that Yin Huaizhu was carefully examining in his hand.

Demon-Locking Formation.

Yin Huaizhu turned the pages of the book in his hands without even looking up, and asked indifferently.

"Are they all registered?"

Yinqian withdrew her gaze from the book: "All the newly awakened spirits, monsters, and souls that have cultivated themselves are in there."

Yin Huaizhu nodded lightly: "Mm."

He continued to carefully peruse the book in his hands, without saying anything more.

Yin Qian paused, glanced at Yin Huaizhu who had stopped speaking, and asked hesitantly.

"That demon in your house..."

Yin Huaizhu stopped flipping through the pages, glanced at Yunqian standing in front of her, and then lowered her eyes again.

His tone remained indifferent: "No need."

All sentient spirits, monsters, and creatures registered here will have their locations and movements recorded in detail.

Even though they can't cultivate into human form or become demons now, they can still separate from their original bodies and condense into spiritual bodies to roam around.

Once it's registered and stamped with the entity's seal, it's essentially subject to constraints in a sense.

If they do not stay at home and disturb the world, as long as there is a record, they will not be able to escape no matter where they go.

Hang Suisui is the first person in several generations to cultivate into a demon since Yin Huaizhu took over this place.

The techniques for controlling demons have long been abandoned.

Jinqian nodded, then, as if remembering something, said something else.

"In the pine forest of Wuzhong Mountain, there was a small pine spirit that had become quite powerful. It did not want to be restricted by the printing book, so it ran away when the people who came were not paying attention. Several people guarded its body for several days, but it did not return."

Yin Huaizhu's slender, fair fingers caressed a corner of the book's pages as she slowly spoke, "Go to the storage building and get the guiding lamp."

Jinqian nodded and said, "Yes."

After speaking, Jinqian turned around and went downstairs.

But then someone behind him called out to him.

Yin Huaizhu put down the book in her hand, looked up and said to Jinqian who was standing at the top of the stairs.

"Wait, have all the guards come back. I'll go in person in a few days."

Jin Qian was somewhat surprised to hear this. Usually, they would handle these matters and then report them. How could such a thing be so troublesome as to require Yin Huaizhu to go in person?

Yin Huaizhu did not miss the surprised look on Yunqian's face, and his fingers brushed over the pages of the book that had just been put down on the table.

He stroked the large characters above and the annotations on the formation below.

He leaned back in his chair, his fingertips tapping the book, making a few crisp sounds.

Yin Huaizhu casually curled the corners of her lips: "Perfect for practicing with it."

Seeing the chilling smile on Yin Huaizhu's lips, Jinqian straightened his expression, nodded knowingly, and quickly replied, "Yes, Master."

I don't know what that little demon did to offend this evil spirit again, that he came back late at night to study some kind of demon-locking formation.

What I saw before was a simple and crude demon-binding formation, but today it has become a demon-locking formation.

As the name suggests, the Demon-Locking Array imprisons something within a certain space, preventing it from escaping.

Although it is gentler than binding the opponent directly by using a demon-binding formation, it is still more powerful.

The former can only last for a period of time, while the latter can last until death.

If a master of formations were to intervene, trapping them for a hundred years would not be a problem.

After Yin Qian left, Yin Huaizhu looked out the window. The lights downstairs were bright, and a mysterious and hazy mist permeated the vast courtyard.

It is a gathering place for countless tiny and agile spirits and monsters.

These essences are like elves, sometimes appearing in a blurry form, and sometimes hiding in nothingness, making it difficult to grasp their true form.

They seemed to move freely in this special space, drifting like phantoms.

Spirits that cannot cultivate into human form still love to condense into human form, but no matter how similar their appearance may be, they cannot be as flesh and blood as demons who have cultivated into humans.

Although they are all skilled at manipulating elemental power, they may not be enough to deal with the people in this building.

However, if he were to face ordinary humans outside, he could easily hurt them if he were not careful.

Yin Huaizhu withdrew her gaze and pulled herself back to reality.
