Chapter 131 Invincible Physics

Worried that the sword would be difficult to repair if it was damaged, Luo Qing took the sword spirit out separately, beat it black and blue, and then put it back in.

The [Radiant Sword] huddled to one side, trembling and weeping.

'How come Yan Guang's strength has increased so much?' Luo Qing frowned and pondered after beating Yan Guang.

After collapsing back into the quantum world and greeting his first disciple, Luo Qing summoned all the spirit swords and other spiritual artifacts.

With a quick sweep of his divine sense, he discovered that all of the few million spiritual weapons had experienced varying degrees of enhancement, with the strongest spiritual sword emanating an aura that even he couldn't quite grasp.

Like the Xuanbing Sword, which once shone brightly in the subterranean fire disaster, this high-level magical artifact that did not develop sentience now has a sword spirit flying around.

What the hell? !
Luo Qing summoned his former sword, the [Dawn and Dusk Sword]. This once high-level spiritual weapon was surrounded by a mysterious yin-yang aura, seemingly having faintly touched the shackles of a semi-immortal weapon, but like him, it was completely unable to break through.

After the [Dawn and Dusk Sword] arrived in front of Luo Qing, the sword spirit respectfully bowed to Luo Qing.

"Owner."

Luo Qing frowned and asked, "In the fifty years I was gone, how many magical artifacts have developed sentience?"

“Uh…” [Dawn Sword] looked embarrassed.

"What's so hard to say? As the leader, didn't you do any statistics?"

"The statistics have been compiled," [Hunxiaojian] said respectfully.

"explain."

“Basically, there are no more magical artifacts left.” The tip of the [Dawn and Dusk Sword] pointed to the sea of ​​quantum magical artifacts. “They have all been upgraded to magical artifacts.”

Luo Qing took a step back tactically and looked into the distance in shock.

Millions of artifact spirits appeared, bowing respectfully to Luo Qing: "Greetings, Master!"

Then the spirit artifacts shouted in unison to Lin Yun, who was next to Luo Qing, "Greetings, Senior Sister!"

Quantum Lin Yun stood there, holding her [Cloud Sword], somewhat helplessly.

"You absorbed all the spirit stones I brought? No, no." After saying this, Luo Qing quickly realized the problem. In the distance, the mountains composed of quantum spirit stones and quantum spiritual energy still permeated the entire quantum world.

The spirit of the [Dawn and Dusk Sword] bowed its head and replied, "Master, we did not absorb any spirit stones. We all know that they are for Senior Sister's cultivation. We... uh, we didn't actually do anything."

"You didn't do anything and yet you managed to upgrade so many spiritual artifacts? You didn't secretly go back to Kyushu to upgrade behind my back, did you?!" Luo Qing exclaimed in disbelief.

"How is that possible?" [Dawn and Dusk Sword] said helplessly, its sword spirit pointing to the yin and yang energies surrounding its body.

"To be honest, Master, I think I need to have a name, and a five-character name would be more imposing."

"What do you want to call me?" Luo Qing gradually calmed down.

"My senior sister taught us a lot about Earth culture. I like Du Fu's line, 'Nature bestows its most wondrous beauty, dividing day and night with yin and yang.' How about I name myself 'Yin-Yang Dawn Sword'?"

"Granted." Luo Qing nodded. He tried to calculate something with his fingers, but since there was no Heavenly Dao in this universe, these calculations based on the Heavenly Dao had no effect. After thinking it over, Luo Qing looked at Lin Yun.

The master and apprentice, now somewhat estranged after fifty years, stared at each other awkwardly.

Luo Qing, too lazy to be coy, asked bluntly, "Lin Yun, what level are you at now?"

"Golden Core, mid-stage Golden Core," Lin Yun stammered.

"Focus on your cultivation and strive to return to the macrocosm as soon as possible. All the cultivation resources here are at your disposal, so don't slack off." After giving this advice, Luo Qing asked, "Have you noticed when the magical artifacts here were upgraded? Is there a unified time? For example, did they suddenly break through on a large scale at a certain moment?"

Lin Yun answered honestly, "No, I observed them a long time ago. The magic artifacts basically increase at a steady rate. After reaching the edge of the spiritual artifact, they will automatically generate spirituality and then start to break through from the low-level spiritual artifact."

Are the increases the same?

"They are different. Magic artifacts with good aptitude and materials will be upgraded relatively faster."

"What about high-level spiritual weapons, like the [Dawn and Dusk Sword]?"

“High-level spiritual artifacts can also break through, but they can only break through to the level of top-level spiritual artifacts. After that, they can give birth to extraordinary phenomena, like this one.” Lin Yun pointed to the Yin-Yang Dawn Sword that was spinning around beside him.

Where is your [Cloud Sword]?

[Cloud Sword] has been a top-tier spiritual weapon ever since it accompanied Luo Qing through the transmigration. If it weren't so feminine and something that a certain evil Hehuan Sect saintess didn't want, Luo Qing might have picked it up as his sword.

The sword spirit of [Cloud Sword] leaped out of the sword, surrounded by ethereal clouds, and stood on Lin Yun's shoulder, bowing respectfully.

[Reporting to the Sword Master, my realm is still that of a Spiritual Weapon, but my power level is already approaching that of a Half-Immortal Weapon.]
Luo Qing remained tactically silent. Even a semi-divine artifact has arrived? Damn it, what's going on here?

Luo Qing believed that his strength came from his diligent meditation and cultivation. Although he had not yet broken through to the Nascent Soul stage, his increased combat power was understandable.

But how come these magical artifacts automatically upgrade?

Let alone spiritual artifacts, even ordinary immortal artifacts don't cultivate automatically. Luo Qing has only seen one spiritual artifact that can cultivate and advance automatically, and that is the Yin Yang Heavenly Seal, the top spiritual treasure.

Looking at the Cloud Sword, which was already approaching the level of a semi-immortal artifact, Luo Qing suddenly had a flash of inspiration: "Cloud Sword, can you freely collapse back into the macroscopic world?"

Because artifact spirits are not true living beings, it is even more difficult for artifacts to break through the observer effect and collapse into a state of existence. High-level artifacts comparable to those of Nascent Soul and Body Integration cultivators cannot collapse back into the real world, but semi-immortal artifacts comparable to those of Tribulation Transcending cultivators should be worth a try.

After all, artifact spirits are acquired spirituality, and most artifact spirits are considered lucky if they have the temperament of a child. Otherwise, that farcical artifact revolution would not have happened.

As expected, the spirit of the [Cloud Sword] nodded hesitantly: "I should be able to... break through the general observer effect and return to the macroscopic world."

really.

"Dawn and Dusk, can you collapse back into the macroscopic world?"

Upon hearing this, the [Yin Yang Dusk and Dawn Sword], who was amusing himself, said seriously, "I'll give it a try."

The next moment, it appeared in the vacuoles of Mercury, but was immediately scanned by the electronic camera inside the vacuoles and annihilated back into a quantum state.

[Yin Yang Dusk and Dawn Sword] was unconvinced and charged out several more times, but each time it was suppressed by the observer effect in an instant.

"Not really." [Yin Yang Dusk and Dawn Sword] shook his head.

Luo Qing then had the [Kunyue Chenxiao Sword], [Qingmu Lingxin Sword], [Canghai Yuntao Sword], [Yuheng Sword], [Fuyao Sword], and [Xuesha Sword], which had already been upgraded to top-tier spiritual weapons, try them out one by one.

A certain electronic camera can quickly and effortlessly obtain seven top-tier magical artifacts.

Luo Qing: “…”

Sure enough, without my help, these magical artifacts would not have been able to appear in the world. The [Evolving Light Sword] was able to stay outside and keep watch purely because of the constant assistance of a wisp of my unconscious soul.

Luo Qing sat cross-legged in the quantum world, pondering for a long time. Lin Yun did not disturb him, but instead dispelled the noisy spirit artifacts.

After an unknown amount of time, Luo Qing suddenly spoke.

"Lin Yun, do you know the law of conservation of energy?"

Lin Yun answered seriously: "I know. The standard concept of the law of conservation of energy is: energy can neither be created out of thin air nor disappear out of thin air. It can only be transformed from one form to another, or transferred from one object to another. In the process of transformation and transfer, the total amount of energy remains unchanged."

Luo Qing nodded emphatically: "Yes, the law of conservation of energy is definitely not wrong! I firmly believe in this! Therefore, the advancement of these spiritual artifacts must be traceable. After thinking it over, I believe that there can only be one type of energy that can appear in the quantum world. It must be the existence of this energy that led to the collective advancement of the spiritual artifacts!"

"You mean..."

"Vacuum zero-point energy!" Luo Qing suddenly realized, revealing a confident smile.

Lin Yun remained tactically silent.

“Your old friend Ding Yi told me about vacuum zero-point energy. He said that the energy source of the sophon is vacuum zero-point energy.”

Luo Qing, posing as a physicist (though he once was), stood with his hands behind his back and said, “According to the uncertainty principle of quantum mechanics, even in an absolute vacuum environment, the quantum field will have tiny fluctuations. The energy of these fluctuations is the zero-point energy of the vacuum, not to mention in the quantum world, it will only be more.”

Lin Yun dared not speak.

Luo Qing grew increasingly excited, brimming with confidence. He quickly articulated a self-consistent logic: "Vacuum zero-point energy exists throughout the vacuum space of the entire universe. Whether on a macroscopic or microscopic scale, wherever there is a vacuum region, there exists vacuum zero-point energy. Moreover, theoretical calculations show that the energy density of vacuum zero-point energy is extremely high. Each cubic centimeter of vacuum space contains up to 10 to the power of 13 joules of vacuum zero-point energy. This immense energy is almost comparable to top-grade spirit stones. It's not surprising that various spiritual artifacts and magical implements can advance in this high-concentration energy field! The vacuum zero-point energy in the universe is practically limitless!!!"

"The only thing I can't figure out is why the zero-point vacuum can be absorbed just like spiritual energy?"

Lin Yun nodded obsequiously, not daring to utter a sound.

She had a feeling that things might not be as simple as Luo Qing said, but she knew that Luo Qing was essentially a very old-fashioned person, especially when it came to "respecting teachers and valuing the way." As his disciple, she absolutely could not question him at this time.

"Ah! So that's how it is! I understand now! Physics is great! I really need to study more physics!"

Luo Qingdao was overjoyed and couldn't help but let out a long roar. Then, realizing that his disciple was beside him, he awkwardly collapsed back into the macroscopic world.

Lin Yun rubbed his face expressionlessly.
