Chapter 69 Rosalin’s last memory fragment!
  [Soul Necklace (Epic): A necklace that can host souls. Current number of souls (1)]

When Su Xuan saw this epic-quality soul necklace worn by Natasha, he was very curious. But what shocked him even more was that there was actually a soul in this necklace.

Whose soul?

"Mr. Su Xuan, do you care about my necklace? Or..." Just as Su Xuan was concentrating on observing the soul necklace on Natasha's snow-white neck, Natasha asked softly with a shy tone.

Su Xuan immediately turned his attention elsewhere and asked, "Does this necklace have any special meaning to you?"

"Hmm~"

Natasha nodded gently and explained to Su Xuan, "This necklace is a treasure passed down from generation to generation in our family. It will play a key supporting role in the process of using the soul secret method."

"In addition to playing an auxiliary role in the process of casting the soul secret method, does it have other uses? For example, there may be a soul hidden in it?" Su Xuan asked in a deep voice.

"There is a soul hidden inside..."

Hearing this question, Natasha's eyes flashed with fear, and she said softly, "Mr. Su Xuan, don't scare me!"

"I'm just guessing. If you're really worried, I can help you check it out after it's over." Su Xuan comforted with a smile.

"That's great~" Natasha patted her chest lightly and breathed a sigh of relief, "After I complete the soul secret method, Mr. Lao Suxuan will check it for me."

After the conversation, Natasha took off the sapphire necklace from her neck and handed it to Su Xuan.

He continued, "Mr. Su Xuan, please hold this necklace. Rosalin is now a member of your guild. Perhaps it is more appropriate for you to be the intermediary."

"Okay." Su Xuan nodded and held the necklace.

Natasha gently wrapped her hands around Su Xuan's palms. Her palms were soft and warm, making people feel peaceful and comfortable.

"Then~I'll start~"

Natasha closed her eyes and sang softly.

A blue magical halo gradually bloomed in her palm, and the weak light gradually became stronger, as if it would illuminate the entire room.

At first, only blue light flickered in the room, but after a few minutes, Su Xuan was surprised to find that countless afterimages of souls began to emerge around them.

They are intertwined and fluttering around the soul necklace, seeming to be looking for a certain opportunity.

In addition, Su Xuan also noticed that these summoned soul remnants seemed to be female. This may be because during the summoning process, Natasha consciously screened the gender of the remnant souls.

At this moment, a remnant soul stretched out his finger and tried to get closer to Natasha, but was blocked by the invisible barrier of blue magic around Natasha and could not get close.

"No, it's not you..."

Natasha opened her eyes slightly, with a faint blue light flashing in her brown-red eyes. She kept looking at these summoned souls, looking for Rosalin's memory fragments.

In just a few minutes, the room was filled with the afterimages of countless souls.

However, at this moment, suddenly, a unique soul appeared in the room.

Her appearance actually blew away all the other residual images of souls at the moment she raised her finger.

"This is……"

Su Xuan frowned slightly. This summoned soul was obviously unusually powerful.

"Su...Mr. Su Xuan, I seem to have summoned an incredible soul."

Natasha's beautiful eyes narrowed slightly, revealing deep concern.

She didn't expect to summon such a powerful soul at all. After all, there shouldn't be such a strong person near Sunset City. Moreover, this soul seemed to be somewhat unique...

"Wait a minute, I'll take care of her."

"Alice, come here and help."

Su Xuan immediately called Alice through soul dialogue. He urgently needed her help.

Alice's soul cutter has a significant restraining effect on the existence of souls, and is perfect for dealing with undead individuals that only exist in the form of souls. “Master, here I come!”

Alice immediately responded to Su Xuan's call.

Next up!

A pair of dark scissors suddenly appeared in the room, and then launched an attack on the remaining soul.

Swish swish!
  "what!"

Hearing a scream from the remnant soul, it was cut into pieces by Alice's big scissors, and fled here in a panic.

"It's done~ Master, you can continue your work~"

"This is the end?"

Su Xuan was slightly surprised when he saw this scene. Alice could actually control her soul weapon from the air?

This is too convenient...

"It's okay, Natasha."

Su Xuan turned to look at Natasha and told her that the summoned soul had been driven away.

And at this moment, he suddenly found that Natasha was staring at him with tears in her eyes. Her cheeks were slightly rosy, revealing a seductive aura.

"Natasha?"

Su Xuan was a little confused. Could it be that the failure of the soul secret method led to such a result?
  "Mr. Su Xuan, I'm fine, it's just that the soul just reminded me of something." Natasha wiped the tears from the corners of her eyes, her voice was a little low, "Let's continue, we must find Rosalind's soul today. That’s all.”

As she spoke, she activated the soul secret method again to find the last piece of Rosalin's memory fragment.

After the soul secret method was restarted, the number of souls appearing in the room was significantly reduced, and without the interference of the powerful soul, the process became very smooth.

However, due to the long-term consumption of magic, Natasha's body began to become a little weak, and she staggered and almost fell to the ground. When Su Xuan saw this, he immediately supported her with one hand from behind.

"Thank you." Natasha thanked her softly, and then continued to use the soul secret method.

During the contact, he could clearly feel Natasha's soft body. Her skin was softer and moister than that of a young girl, as if it were made of water.

The key thing is that Natasha always sways gently while singing magic, and her gentle movements bring her body into close contact with Su Xuan. The buttocks were gently rubbed, giving off a wonderful touch...

cough~
  Suddenly, Natasha's soft voice came: "Mr. Su Xuan, what do you think will happen to a person if she lacks part of her soul?"

"Lack of soul?" Su Xuan heard this, pondered for a moment, and replied, "Maybe he will become as cute as Rosalin is now."

"Yes~"

When Natasha heard Su Xuan's answer, she smiled slightly and said softly, "People who lack part of their soul will become stupid. No wonder Rosalin is always worried that I will be deceived by bad people..."

"..."

Su Xuan was silent. Ever since he saw that the soul in the White Rose Flower looked exactly like Natasha, he knew that Natasha's identity was definitely not simple.

Although he has not determined the connection between them, the speculation that she is the soul of the White Rose Flower has always been one of the most likely options.

Just when Su Xuan was immersed in his thoughts, Natasha slowly turned around, her clear eyes shining with soft light.

"Mr. Su Xuan~Look~"

She raised her hand slightly, and a fragment of her soul condensed in her palm.

Natasha succeeded!

Su Xuan felt an indescribable joy in his heart, Rosalin's last piece of the puzzle!
  finally come!
