Before opening the sword box, Hongyuan naturally thought in his heart, how fierce and murderous the seven secret swords he set up were after they became real.

Even as described in fantasy novels, just eye contact will be stained by sword qi, and the heart trembles or something......

But the truth is that the situation inside the sword box is completely beyond Hongyuan's imagination.

Xiao Ying's sword box was empty, there was nothing!

As if trying to verify something, Hongyuan picked up the sword box with both hands, and immediately found that the entire sword box was terrifyingly light, as if the sword box was empty from the beginning.

"Impossible!" Hongyuan recalled Xiao Ying's struggling appearance when he carried the sword box on his back, and he could easily judge that Xiao Ying's sword box definitely had "goods" in it.

"Could it be that Xiao Ying used some secret method to collect seven secret swords, leaving me only an empty shell." Hongyuan secretly thought in his heart, and was almost about to go downstairs to question Xiao Ying about it.

Who knows, just as Hongyuan stretched out his hand to push the sword box and wanted to withdraw his gaze, the corner of his eye suddenly caught a glimpse of the sword box, and there seemed to be an illusory and blurred angular outline.

Hongyuan: (O_o)?

At this time, the gap between the sword box had been closed again, Hongyuan's heart moved, and he hugged his hands to move the sword box, and then he was shocked to find that the sword box that was still fluttering just now was so heavy that he couldn't move it.

"What the hell?" Hongyuan opened the sword box again, but the inside of the sword box became empty again, and the weight of the entire sword box became lighter again.

"Wouldn't it!? Could it be that the seven secret swords in the sword box are in a state of superposition that exists and does not exist, just like Schrödinger's cat and Ah Xuan? ”

The mentally ill have a lot of joy, and the fiction writer has a wide thinking!

Hongyuan dragged his chin with one hand. As an online writer, in today's indecisive and quantum mechanics, "Schrödinger's cat" is naturally not a new thing for him.

The so-called "Schrödinger's cat" refers to a thought experiment proposed by the famous Austrian physicist Schrödinger in the 20th century:

The experiment consisted of a cat being kept in an airtight box containing a small amount of radium and cyanide, and a trap was placed near the radium.

Radioactive radium is an unstable element, and if it decays, it triggers a trap to smash the bottle containing cyanide, and the cat is poisoned.

If radium does not decay, the cat will survive.

But quantum mechanics differs from classical mechanics in that the system described by quantum mechanics can be in two different states at the same time without an observer, and the two states will superimpose each other in a probabilistic way.

Therefore, according to the theory of quantum mechanics, radioactive radium will be in a state of quantum superposition that is both decaying and not decaying when there is no observer, so the cat in the box will also be in a state of superposition that is both dead and alive.

And this cat, which is both dead and alive, is "Schrödinger's cat".

At this point, unless an observer appears and the wave function of the system collapses into a definite state, the cat in the box will remain "dead and alive".

The same thing happened to Tang Yunxuan.

The "incident" ten years ago made Tang Yunxuan a quantum ghost between existence and non-existence.

Compared with Hongyuan, Tang Yunxuan is alive and exists.

But compared to other people, relative to this world, Tang Yunxuan actually died ten years ago!

In order to verify his conjecture, Hongyuan began to experiment repeatedly.

He opened and closed the sword case, and opened and closed it again every ten minutes.

Finally, after nearly an hour of trial and error, Hongyuan saw the entity of the Seven Killing Sword inside the sword box.

To be precise, what Hongyuan saw was only one of the Seven Killing Swords.

It was a heavy sword, the sword was gorgeous, but the body of the sword was dark red, the blade was not cold, the edge was not exposed, and there was a deep silence like the sea.

Hongyuan saw that the body of the secret sword was densely covered with bright red textures, like Xuan lines, and like sinuous veins squeezed in the dark red sword body.

At this moment, Hongyuan's heart suddenly had a sense of being watched, and this feeling was so strong.

Hongyuan looked at the source of this feeling, and suddenly his pupils shrank, and he saw that in the center of the secret sword, a blood-red pupil was shaking its pupils, looking straight at him.

At a cursory glance, the pupils of those eyes seemed to be just decorations on the sword, but at this moment, they looked extremely vivid, and their eyes seemed to be full of malice!

Hongyuan's heart shook slightly, and a sentence suddenly flashed in his mind......

When you gaze into the abyss, the abyss will gaze back!

His gaze trembled slightly, and the heavy sword in his vision immediately became illusory, as if he was about to fall from a three-dimensional vision to a two-dimensional vision.

Sure enough, the sword in Xiao Ying's sword box was in a superposition state that existed and did not exist, just like Schrödinger's cat and Ah Xuan. It is only when I open the sword case that the state of the sword is determined, either present or absent. ”

"But since I'm not the owner of the Seven Killing Sword, most of the time, the Seven Killing Sword doesn't exist relative to me."

"Of course, it can't be ruled out that the Seven Killing Sword, like the Fire Punishment Talisman, has anti-physical properties similar to 'containment', if that's the case, it can't be explained with my current knowledge."

"The things in the cultivation world are really weird and strange!" Hongyuan's thoughts rose and fell.

You must know that when online writers write novels, they naturally write bizarre and bizarre ways. But when the objects in the novel are embodied in the real world and appear in the real world, Hongyuan realizes how bizarre and incompatible the characteristics of these objects are from the real world.

For some reason, a feeling suddenly arose in Hongyuan's heart. Xiao Ying's arrival may really be a god in the dark, pushing a new door for him!

If he can communicate with the Xiuzhen world behind her through Xiao Ying and obtain a large number of resources from the Xiuzhen world, maybe he will really have a chance to fight with the Church of the Broken God, and saving his sister and Ah Xuan in the future is no longer just a fantasy and extravagant hope.

"I'm going to take this opportunity very fast." Hongyuan's heart, which was hiding under the appearance of "cynicism", was extremely excited at this moment.

At this moment, the pitch-black Dao Seeking Jade suspended in the sea of Hongyuan Consciousness suddenly began to rotate rapidly, blooming with Dao Dao brilliance!

The terrifying pain struck, and the vast sea of knowledge seemed to turn into a pot of hot oil that was ignited, and it completely boiled.

At the same time, Hongyuan's body seemed to be controlled, allowing his consciousness to scream in pain, but his body could not move a bit.

But Hongyuan could feel that a force was being nurtured with the brilliance of seeking Dao Jade, and this power quickly took shape and quickly surged towards Hongyuan's left eye.

The pupil of Hongyuan's left eye quickly turned bright red, and a very thin black ring appeared around the pupil.

At the same time, an invisible force used the grand pupil as a flashpoint, and suddenly enveloped the dark red giant sword in the sword box.
