Cao Yaxuan learned the Arctic Meditation Technique and then eagerly began meditating.

Everyone watched with anticipation.

The combination of Ultimate Frost Energy and Arctic Mana, even if Cao Yaxuan didn't use a skill and merely touched an enemy with this frost energy, would likely cause massive damage.

It was unknown how much time had passed when a shocking wave of frost energy suddenly erupted from Cao Yaxuan's body.

This frost energy was both swift and fierce, instantly spreading outwards!

"It's out of control!"

Xu Lang's pupils contracted sharply. As the thought flashed through his mind, the purple World-Ending Heterogeneous Flame roared forth, confronting the oncoming frost energy!

Frost and raging fire collided, but instead of an explosion, they reached a stalemate!

The area where Cao Yaxuan was located completely transformed into a frosty hue!

[Nightmare Eye · Cao Yaxuan: Arctic Mana has stimulated the latent power within the Ultimate Frost Energy, causing energy disruption...]

"Everyone, fall back!" Xu Lang barked.

The girls immediately dismissed the various thoughts in their minds and all retreated.

Cao Yaxuan was startled awake by the commotion. A flicker of confusion passed through her opened eyes before she hurriedly nodded, "Agree!"

Instantly, the frost energy retracted, completely annihilated by the heterogeneous flame.

Xu Lang withdrew the World-Ending Heterogeneous Flame. His gaze swept over the still-frozen furnishings around them as he addressed Cao Yaxuan, "Yaxuan, what's going on?"

"The system just prompted me, asking if I wanted to use the Arctic Meditation Technique to fuse with the Ultimate Frost Energy and birth a new skill!" Cao Yaxuan licked her lips, her heart still palpitating with fear. "Before that, I had just extracted one unit of Arctic Mana, and it spontaneously clashed with the Ultimate Frost Energy in my bloodline!"

If the system hadn't intervened, she definitely wouldn't have been able to maintain the balance between the Arctic Meditation Technique and the Ultimate Frost Energy so quickly.

"Then that's a good thing," Xu Xiaomeng spoke up. "Sister Yaxuan, quickly show us your new skill."

Cao Yaxuan nodded. The moment she checked the skill information, she herself was stunned.

[Blood Contract Profound Meaning · Ultimate Mana]

[Type: Ultimate Frost Energy · Blood Contract Skill]

[Level: EX]

[Rarity: EX]

[Effect: Excavates the "Ultimate Mana" hidden within the Blood Contract · Ultimate Frost Energy, simultaneously increasing personal attributes. The higher the Blood Contract level, the higher the purity of the Ultimate Mana.]

[Introduction: Ultimate Mana, the pinnacle power among ice-elemental forces, only passed down within the most orthodox Ultimate Royal Family.]

"Seems like I got something huge," Cao Yaxuan scratched her head. Then she suddenly jolted, exhaling a puff of frosty air, "Holy crap, why did my hair turn blue!"

Her hair now had a hint of icy blue, looking very noble.

"That's a good thing! I feel like you've become even more beautiful, Sister Yaxuan!" Xu Xiaomeng said with a cheerful laugh.

Hearing Cao Yaxuan's tone, Xu Lang didn't need to activate Nightmare Eye to know she hadn't been possessed.

Such a drastic mutation really made him suspect Cao Yaxuan had been replaced.

"Yaxuan, didn't you just use the Bloodline Purification Potion? Your bloodline level increases by two ranks after each round of the game," Wang Yazhi suddenly said. "The Arctic Meditation Technique transforming into Ultimate Mana is equivalent to binding it to your Blood Contract. You'll grow stronger and stronger from now on."

The girls' hearts trembled, their gazes towards Cao Yaxuan tinged with a bit of envy.

Xu Lang also felt somewhat envious.

Previously, when the two cultivation skills fused, he still thought they weren't as powerful as his Innate True Qi. Now, that wasn't necessarily the case anymore.

...

Gymnasium.

Cao Yaxuan fought one against three, forcing Tong Qi, Han Zhixiu, and Zhen Lu to retreat repeatedly.

"Path of Frost!"

"Bloom!"

"Hailstorm!"

Cao Yaxuan stood in the center of the arena like a frost artillery turret.

Frosty corridors, ice flowers blooming with countless icicles, sheets upon sheets of hail... her methods were endless.

Tong Qi, Han Zhixiu, and Zhen Lu weren't going all out either, merely acting as sparring partners.

Truth be told, even if Han Zhixiu and Zhen Lu went all out, they probably still couldn't win...

Enemies in front of Cao Yaxuan only had three tiers.

Can't beat, can beat, and cannon fodder.

The crowd-control ability of frost power was too strong, almost entirely area-of-effect damage!

Facing such methods, even Wang Yazhi would find it difficult, because with attacks covering the entire field, there was nowhere to dodge. Unless she could instantly kill Cao Yaxuan, winning later would be almost impossible.

As she cast spells, Cao Yaxuan's hair grew increasingly bluer, then gradually returned to normal as the Ultimate Mana receded.

However, a touch of icy blue, like ice crystals, remained in her hair.

"Enough, enough! I'm not fighting anymore!" Cao Yaxuan shouted loudly after about ten minutes.

Zhen Lu and the others had sustained varying degrees of injuries. Even though Cao Yaxuan hadn't intended to actually kill, they couldn't avoid getting grazed by the frost.

Sherry went up to provide treatment.

"Sister Yaxuan, why stop fighting?" Xu Xiaomeng asked.

This was her first time experiencing such an intense battle, and she felt it ended too soon.

"Out of mana," Cao Yaxuan waved her hand.

Xu Lang asked, "What's the recovery rate of your Ultimate Mana like?"

"If I meditate, recovery is very fast. My current upper limit is 50 units, probably restricted by my Blood Contract level," Cao Yaxuan replied.

[Cao Yaxuan]

[Attributes: Constitution 44, Spirit 148, Ultimate Mana 0] 𝙛𝓻𝒆𝓮𝒘𝙚𝙗𝒏𝙤𝙫𝓮𝒍.𝓬𝒐𝙢

[Skills: Blood Contract · Ultimate Frost Energy, Blood Contract Profound Meaning · Ultimate Mana, Low-Tier Ice Magic...]

"Yaxuan, you're so strong, really strong!" Tong Qi looked at Cao Yaxuan and said sincerely.

Casting with Ultimate Mana required no preparation time, and the frost weapons it condensed were extremely hard, with terrifyingly low temperatures.

Forget casting spells with Ultimate Frost Energy; even simply releasing it could instantly kill a large group.

"I think it's just average!" Senior Sister Red Butterfly curled her lip disdainfully.

"Then you come and try it!" Cao Yaxuan wasn't about to indulge Senior Sister Red Butterfly.

"Red Butterfly, Yaxuan's Ultimate Mana counters you the most. Your powerful healing is useless!" Sherry admonished.

That statement was something else, directly igniting the fire of debate.

It wasn't like the old days anymore.

If they really fought now, people could actually die, so they could only vent with words.

...

Night.

Xu Lang lay on the Nightmare Bed, peacefully falling asleep.

Cao Yaxuan and the others were Pioneering at this time.

Of course, they were just playing around outside, not delving deep.

But this was still much more diligent than the slacking Xu Lang.

Xu Lang, the one with the Blood Pelican Demon Blade and the Blood Rakshasa Blood Contract, was the one slacking off instead.

No helping it, this was his fastest growth method.

Within the simulated dream, the Constitution Limit Break Trial was underway, costing several hundred Nightmare Essence per attempt, frighteningly expensive.

The dreamscape shifted.

Xu Lang appeared in a sealed palace, with four Roman pillars supporting the dome.

"Hey, we meet again, kid!"

A familiar voice came over.

Xu Lang looked at the skeleton holding a black-bladed sword in front of him and tilted his head, "You're the Purple Cape Skeleton?"

"Call me Raphael, Imperial Guard of the Blood Empire!" the skeleton stated solemnly, then stared at Xu Lang with a mocking laugh, "You didn't really think you defeated me, did you?"

"So this is your second phase?" Xu Lang rested his hand on the hilt of the sword at his waist.

Yes, for the second round of the Constitution Limit Break Trial, he had a weapon.

[Blood Empire Standard Long Blade: A standard-issue weapon crafted by the Blood Empire for elite soldiers, excellent workmanship]

"Hah, otherwise? You didn't think a distinguished Imperial Guard like me would only rely on a divine weapon to deal with you, did you?" Raphael swung his long blade, a sharp glint suddenly flashing in the soul fire of his eyes. "You need to be careful this round. I was the third-place winner in the Blood Empire Master Tournament. This round, I'll demonstrate to you what the true path of blade combat is!"

The Senluo Purple Blade had an effect: the holder's blade technique skill levels increased by 1.

If the weapon was that impressive, Raphael in life must have been a true blade master!

"Kid, don't you die on me!"

Raphael let out a strange cry, leaving behind shockwaves resembling Mach rings on the spot. In the next instant, his figure was right in front of Xu Lang.

The blade cuts the flesh, the heart cuts the soul!

Before even swinging his blade, Raphael had already locked onto Xu Lang's vital points!

Then he saw Xu Lang also swing his blade.

The first blade clashed with his own, the second and third blades both slashed onto his shoulders.

Not cool, bro!

I only swung once, how did you swing three times?

"Boring," Xu Lang looked at Raphael, who had smashed into the wall, and sheathed his blade.

The Mad King's Limit Break Trial's difficulty is still too low.

Is there a Nightmare Limit Break Trial?

The kind that matches the identity of the Nightmare Lord.
