In his rage, the Nascent Soul Cultivator from Emperor's Extreme Heaven Splitting Dao did not notice that as he continued his fierce attacks, layers of the Dao Heart Pure Yang Mirror gradually blocked his line of sight.

Earlier, the Heart Demon Great Curse had suppressed his Spiritual Sense. He could no longer observe anything.

After eliminating the last unnecessary observer, Wang Qi did four things.

First, he input a command that triggered the explosion of the Thousand Illusion Divine Spell power accumulated inside the Nascent Soul Cultivator from the Unrivaled Sword Sect, while at the same time, the power of the comprehensive Divine Plague Curse flowed into his body along the pathways established by the Thousand Illusion Divine Spell.

Second, he used the Dao Heart Pure Yang Mirror to block the now harmless Nascent Soul Cultivator's vision.

Third, he employed the Unpredictable Body Technique to run next to the Cultivator from the Heavenly Book Tower.

Fourth, he executed the Mysterious Uncertainty Cloud Sword.

At the moment of being struck, the Cultivator from the Heavenly Book Tower sensed something different. The apex of the Heavenly Book Tower's cultivation techniques could evolve into the Taixu, Taiji, and the Great Dao of Innate Fate among the Innate Five Taos, and it delved deeply into causality and transformation. In that final moment, it seemed he truly saw something...

So many... so many...

So many swords...

Only then did he realize.

"Cause precedes the effect, the cause becomes the effect..."

Right at that moment, a Light Saber descended from the sky. The Dao Heart Pure Yang Spell's system overloaded, stuttered, and the vestment robe on Wang Qi momentarily turned into a snowy static - like the unsightly mosaic that appears during a poor signal transmission.

"The move just now, that was the so-called unknowable, unpredictable Unpredictable Body Technique, and then your sword just now..." he almost shouted: "Mysterious Uncertainty Cloud Sword..."

Ah, a reminder to his companion.

Of the three Heart Demon Great Curse divine garments Wang Qi possessed, only the Thousand Illusion Flute remained. Yet, he indifferently glanced at the Nascent Soul Cultivator from Emperor's Extreme Heaven Splitting Dao in the sky, revealing a playful smile.

Meaning, "Coming again?"

The Nascent Soul Cultivator from the Unrivaled Sword Sect was terrified by the rapidly evolving power of the Heart Demon Great Curse during their duel and was lured by the Thousand Illusion Joking Flute Sound into exposing his Heart Demon, already ensnared by the comprehensive Divine Plague Curse. Meanwhile, the Heavenly Book Tower Cultivator was already internally injured, struggling to flee, and his Mana was scattered by the Mysterious Uncertainty Cloud Sword, showing signs of losing control.

What would this Nascent Soul Cultivator from Emperor's Extreme Heaven Splitting Dao choose to do?

Wang Qi watched the Cultivator silently, then turned and retreated.

Wang Qi smiled and looked at the Cultivator from the Heavenly Book Tower. The Mysterious Uncertainty Cloud Sword had already dispersed his Mana; he couldn't even destroy his own Nascent Soul. Moreover, during the recent combat, plenty of Heart Demon Curse power had invaded his body; he was now like meat on the chopping block, nothing to be afraid of.

The Cultivator from the Heavenly Book Tower felt a chill in his heart, assuming a desperate stance. However, Wang Qi did not feel like fighting to the death, continuously retreating. The Heavenly Book Tower was famous for its numerous magic techniques, who knows what kind of special self-destruction skills this guy might have? He genuinely had a deep psychological shadow over self-destruction. Moreover, he had better options.

Soon, the Cultivator from the Heavenly Book Tower felt more than just a chill in his heart. The chill seemed to seep into his veins.

When he fell, his body was also emitting a faint blue glow.

At this moment, Wang Qi casually rebooted the Yellow Robed King's system. Then, he released the Sword Array around Mao Zimiao. He approached the Cultivator from the Heavenly Book Tower and asked, "What's your name?"

The Cultivator from the Heavenly Book Tower looked at Wang Qi woodenly: "Why should I answer your question?"

"Aren't you afraid I'll kill you?"

"Does it matter if I die sooner or later?" the Cultivator from the Heavenly Book Tower asked indifferently: "Falling into your hands, I had no plans of living..."

Despair had set in, but it wasn't enough. His mind was deeply distorted, and there was a chance of losing precious information...

Wang Qi frowned, then asked, "What do you think of the sword I used just now?"

Surprisingly, as soon as Wang Qi uttered these words, the dignified Nascent Soul Cultivator, like a startled bird, immediately jumped up from the ground and back: "Terrifying! Terrifying!"

Wang Qi initially thought he was a saintly character on the outside and resistant on the inside, capable of withstanding the Heart Demon Curse. It appeared he was just feigning being cursed to achieve mutual destruction with him. But his words made Wang Qi realize, unable to hold back, he grabbed his collar urgently, asking, "What did you see?"

"Swords... so many swords..." The Nascent Soul cultivator's legs feebly thrashed as he rambled, "Terrifying... I was struck by so many swords... In the end, there was only one sword... so many..."

"So many swords?" Wang Qi demanded, "What exactly is it? An infinite past? Or infinite incidents?"

Is it multiple histories, or multiple worlds?

This was his most pressing concern.

Just now, he hadn't intended to spare the other's life on purpose but because he truly couldn't kill him—his sword moves weren't strong enough. This wasn't to say that the Mysterious Uncertainty Cloud Sword, which had already slain numerous Nascent Soul cultivators, had a problem, but because the Mysterious Uncertainty Cloud Sword he used was his own modified version. He had removed the Copenhagen Interpretation and introduced other theories. It was still incomplete, and in a moment of quantum cloud sword Qi exposition, it unexpectedly couldn't unfold and failed to strike the most critical vital point during the collapse.

This level of magic was no longer the ordinary magic that Wang Qi used to tinker with. Wang Qi estimated it would indeed take him two or three years to resolve this issue. Although Zhen Chan said what Wang Qi was doing would take an ordinary person two to three hundred years, Wang Qi knew better. His magic was leveraging the Established Method of Mysterious Palace, while his theory was standing on the shoulders of an entire generation of Feynman's Earth physicists; taking two to three years still felt slow to him.

And completing this transformation would also complete Wang Qi's understanding of "Spiritual Energy." According to Wang Qi's estimates, the moment he could unleash "that one sword" would be when he ascended to the Golden Core stage. At that time, the path to Primordial Spirit would also reveal itself before him.

"The cause of infinity leads to the stable outcome..." The cultivator shrieked, "Terrifying! It's too terrifying!"

Wang Qi knew that he wasn't likely to extract anything useful now, so he used the Supreme Heart Demon Curse to thoroughly inflict the cultivator, seizing his mana. Zhen Chan witnessed this and couldn't help sighing, "The Heart Demon Great Curse really is... a terrifying thing. Nascent Soul Cultivator, with at least a Mental State Perfection, like Bright Mirror Lake..."

"It is invulnerable against those below Golden Core, but it poses several difficulties against Nascent Souls, requiring gradual infusion of the Heart Demon Curse Power during combat, which is quite troublesome. As for Divinity Transformation Cultivators... I reckon they can't be tainted in the short term."

The higher the cultivation of the cultivator, the heavier their personal imprint on their mana. In terms of Modern Method, it means that their mana's intrinsic form is closer to their own soul, allowing mana to become a carrier for thoughts. By the stage of Zhao Qingfeng's previous life's Immortal Realm, even a thread of immortal power could reincarnate independently. The higher the realm, the more sensitive they are to "foreign bodies" within the life system, making the Heart Demon Curse harder to invade.

If it were a Demon Path Cultivator, who does not contemplate mental state or true intent, perhaps on detecting an invasion of the Heart Demon Curse, they could only self-destruct part of their soul. However, if it were a cultivator from the Mysterious Sect or one of Emperor's Extreme Split Sky Dao's type who practiced with a bent sword path, it's possible they might not be tainted at all.

Of course, discussing toxicity without dosing is nonsense. If Wang Qi spread the Heart Demon Curse all over the world and then gathered a Supreme Heart Demon, even a True Immortal might fight it off.

Zhen Chan seemed puzzled, "Then do you still plan to contend with those at the Divinity Transformation Stage?"

"If it really comes down to it, it'll just be a few shots of the Sky Dragon Slaying Sword Qi," Wang Qi said. "Once the system from the Yellow Robed King is ready, I can at least withstand one move. Afterwards, maintaining my Unpredictable Body Technique..."

Zhen Chan solemnly said, "Don't be too naive. Do you know how strong a Divine Separation Stage Cultivator is? That dragon last time was problematic, which is why you could hit it easily. If it were a real Divine Separation Stage Cultivator, not to mention that his casual attack would broadly exceed the probable existence range of your Unpredictable Body Technique, his magic body is also stable, not to be exploded by your Foundation Establishment sword energy. Just speaking of reaction alone, when you are maintaining your Unpredictable Body Technique, you yourself wouldn't know where you are, what your speed is, how can you aim? The moment you exit your Unpredictable Body Technique to aim, he could kill you ten times over..."

Wang Qi remained calm, "I know."

"If you know, then why..."

"It's not like we haven't fought during Divine Capital battle," Wang Qi replied.

That sulfur-based creature transformed into Lu Wan most likely possessed Divine Separation Stage combat power. However, back then, he was stubbornly clinging to "Immortal Characteristic," insisting on competing with Wang Qi in "stepping out of the long river, mastering oneself," turning the fight into a computation power competition, ultimately defeated by Wang Qi. If he had seriously used more fundamental tactics against Wang Qi, Wang Qi probably wouldn't have won.

Wang Qi just shrugged his shoulders, "Who told you I planned to fight head-on?"

Zhen Chan looked confused, "Aren't you planning to rescue Ai Changyuan and Wu Shiqin?"

Wang Qi tapped on the three Heart Demon Curse Memory Bodies on his arm armor, "Remember the original use of these?"

"Original use?" Zhen Chan immediately recalled Wang Qi's old habit of distributing "Boluo Divine Flame" to everyone he met: "To trick people?"

"Otherwise, why do you think I let that guy run away? Right now I'm in peak condition, just a mere Nascent Soul, and even without using such cheating methods like the Heart Demon Curse, I could easily wipe him out," Wang Qi sneered. "What is he carrying? The Heart Demon Curse! The Heart Demon Curse that once tainted is absolutely irreversible!"

"He'll lead the way for us. Jarvis has already recorded his movement route. He will clear a safe path for us. As soon as he approaches other Ancient Method Practitioners, the power within him will completely burst forth, making him collapse in front of his companions."

"What do you think, what will be the first reaction of those Ancient Method Practitioners seeing their companion fall?"

Zhen Chan was at a loss for words.

Upon seeing their companion fall, cultivators generally use safe methods to lift them—like using spirit pets, puppets, magic artifacts, etc., to carefully verify any strange poisons, Absolute Gu, or triggering talismans on their bodies before personally touching them, imagining almost all anticipated types of traps would generally be guarded against by the cultivators. But, the Heart Demon Curse is not at the same level as those.

An ancient thief might know how to break any tomb mechanism. However, they certainly wouldn't anticipate a Broadsword Mine.

Wang Qi smiled slightly and added, "Actually, I also set a Divine Plague Curse."

Zhen Chan was shocked, "When?"

"Just now. That Emperor's Extreme Split Sky Dao thought he had removed himself from the battlefield." (To be continued. If you like this work, you are welcome to vote for it on Qidian.com, and your support is my greatest motivation. Mobile users please go to m.qidian.com to read.)
