Sixth-Rank Magic Core

After the Purple Crystal Winged Lion King's attack entered her body, Yun Yun immediately felt the Dou Qi within her slowly fading away.

Although the speed was not fast, Yun Yun's heart sank.

Seeing that its Purple Crystal Seal had successfully entered Yun Yun's body, the Purple Crystal Winged Lion King immediately lunged before her, raised its enormous claw, and viciously slashed at her chest.

"Extreme Wind: Meteoric Kill!"

Just as the Purple Crystal Winged Lion King's massive paw was about to fall, the longsword in Yun Yun's hand trembled violently. A tiny, illusory cyan sword shot toward the Purple Crystal Winged Lion King's head.

The little sword's power was terrifying. The moment it appeared, even the surrounding space trembled several times.

The Purple Crystal Winged Lion King's senses were sharp. The cyan sword gave it an extremely terrifying feeling, and it hurriedly tried to dodge.

At that moment, Xiao Yun, hidden in the shadows, moved. He reached out and made a grasping motion at the Purple Crystal Winged Lion King's enormous body. Instantly, its body froze in place, unable to move.

Not only that, the Purple Crystal Winged Lion King realized that it could not even make a sound.

There was a powerful expert hiding nearby!

That was the Purple Crystal Winged Lion King's final thought. Even in the underworld, it would not understand why someone so powerful had hidden away to ambush it.

The cyan sword shot precisely into the Purple Crystal Winged Lion King's head, then burst out from the other side, piercing straight through its entire lion head.

The Purple Crystal Winged Lion King, ruler of the Magical Beast Mountain Range, was slain by Yun Yun just like that.

The Purple Crystal Winged Lion King's body crashed to the ground, kicking up a sky full of dust.

Yun Yun slowly descended while dragging her heavily injured body. The instant she landed, she spat out a mouthful of blood, her cheeks slightly pale.

Looking at the Purple Crystal Winged Lion King's corpse, Yun Yun was puzzled.

"Clearly, it could have avoided the vital point. Why did it suddenly stop moving?"

"Of course, it was because I was hiding in the shadows to ambush it—no, because I was secretly helping you." Xiao Yun appeared beside Yun Yun like a ghost and said.

"Who's there?!"

The sudden voice startled Yun Yun. She turned around, and a somewhat familiar face entered her sight.

Looking at Xiao Yun, Yun Yun felt he was familiar, yet she could not recall where that familiarity came from.

"Who are you?"

Yun Yun raised the longsword in her hand slightly and looked at Xiao Yun warily.

Seeing this, Xiao Yun pretended to be angry. "You don't even recognize me anymore? Wife, you've changed. You don't love me anymore."

"Wife?" Yun Yun froze upon hearing that form of address.

Suddenly, something came to mind, and she said in shock, "You're Xiao Yun!"

The memories in her mind awakened. Yun Yun remembered that from childhood to adulthood, Xiao Yun was the only person who had dared to call her wife.

Seeing that Yun Yun recognized him, Xiao Yun smiled. "Looks like my wife still loves me."

Yun Yun's face reddened, and she hurriedly denied it. "Who's your wife?"

"Back then, someone dragged four-year-old me into a bet. She said that if I lost, I would marry her when I grew up, and if I won, I would take her as my wife when I grew up."

"Who would have thought that after only eighteen years apart, someone would turn her back on her word?"

"Hmph. Heartless woman."

Yun Yun's mouth twitched. At that moment, she deeply regretted being captivated by Xiao Yun's adorable appearance when she first met him.

Smitten with Xiao Yun at first sight—no, it had been love at first sight—she had dragged him into a bet. If she won, she would marry Xiao Yun when she grew up. If she lost, Xiao Yun would marry her when they grew up.

Thinking about it now, Yun Yun wanted nothing more than to slap herself twice. It was far too embarrassing. How could her younger self have done something like that?!

"I was young and ignorant back then. It doesn't count," Yun Yun said hurriedly.

Xiao Yun shrugged and continued, "Someone also said back then that she wasn't a three-year-old child anymore. Once a promise was made, it had to be honored for life, or she wouldn't be able to find a wife after growing up."

"Good grief, I'd only had my fourth birthday a few days before that, you know?"

"Cough, cough." Yun Yun's head felt hot. Every word Xiao Yun said filled her with unbearable embarrassment.

Xiao Yun smiled slightly when he saw this. Feeling that he had teased her enough, he changed the subject and asked, "Forget it. Let's not bring up childhood matters. What are you doing here looking for Purple Spirit Crystal?"

Seeing that Xiao Yun had finally let her off, Yun Yun felt as though she had been granted a reprieve.

"I need Purple Spirit Crystal for Yanran. There is a Medicinal Pill that can accelerate Yanran's cultivation."

When Nalan Yanran was mentioned, Yun Yun looked slightly embarrassed. "You should have met Yanran. She was the girl who went to the Xiao Family a few months ago to break off the engagement. You even had her deliver a message to me."

Xiao Yun nodded and smiled. "Niece Nalan? Of course I've met her."

Seeing that Xiao Yun showed no sign of anger when he mentioned Nalan Yanran, Yun Yun hesitated before asking, "Aren't you angry?"

"What is there to be angry about? Niece Nalan wasn't wrong to want freedom from the marriage agreement. Her method was just too extreme."

"Besides, she and Xiao Yan made a Three-Year Pact. Matters between the younger generation should be settled by themselves."

Although Xiao Yun did not particularly like Nalan Yanran, he did not hold much ill will toward her either. In any case, Xiao Yan would make Nalan Yanran regret it.

Xiao Yun walked over to the Purple Crystal Winged Lion King's head and reached in to retrieve a Magic Core.

Xiao Yun would not pass up such a good thing as the Magic Core of a Sixth-Rank Magical Beast.

Holding the Magic Core, Xiao Yun looked at Yun Yun and asked with a smile, "I'm taking this Magic Core. You don't mind, wife?"

"I told you not to call me wife!"

Yun Yun did not compete with Xiao Yun for the Purple Crystal Winged Lion King's Magic Core. She merely cut off one of the Purple Crystal Winged Lion King's claws.

The Purple Crystal Winged Lion King lived in a cave. After searching around, Xiao Yun and Yun Yun quickly found the entrance.

After killing several Third-Rank Magical Beasts guarding the entrance in one move, Xiao Yun and Yun Yun entered the cave.

The cave was not dark. Purple crystal blocks were embedded in the surrounding stone walls. They were exceptionally beautiful and, in the outside world, were precious decorative items worth a great deal.

After walking through the cave for a long time, Xiao Yun and Yun Yun came upon two branching paths.

"Xiao Yun, which way do we go?" Yun Yun frowned. After carefully examining the two passages and finding no clues, she asked Xiao Yun.

Xiao Yun released his Soul Power. His powerful Soul Power spread into both passages. Soon, he withdrew it and pointed to the passage on the left. "This way."

"Alright," Yun Yun said.

After some time, Xiao Yun and Yun Yun finally reached the end of the passage. The temperature here was extremely high.

At the center stood a platform made of piled purple crystal stones. Resting atop it was a purple, spherical object as large as an adult's head.

The heat throughout the cave was actually released by this purple sphere.

Xiao Yun examined the purple sphere and said, "This is Amethyst Birth Essence!"

When a Purple Crystal Winged Lion King gave birth, there was an extremely small chance that Amethyst Birth Essence would be produced. This Amethyst Birth Essence was a good thing, containing pure energy.

If a Purple Crystal Winged Lion consumed it upon reaching Fourth Rank, it could directly become a Fifth-Rank Magical Beast. This showed just how terrifying the energy contained within it was.
