(Wednesday, April 16, 2014, noon; school, club room)

Yuta Tomigashi stared at the computer intently, and the nine big characters of "quantum blockchain financial system" were very conspicuous. In the center of the activity room, the three of them are lined up, and the projection screen is the 4K ultra-clear "Genius Mahjong Girl National Chapter", and the high speed of the 5G network is enough for them to watch online.

"The expected era of technological blowouts!"

He tapped lightly on the laptop's shell — under his fingers, where the optical drive should have been, he had modified it with a programmable nanophotonic processor. Despite its high price, these optical chips are better at processing operations involving multiple matrix multiplications, far outperforming traditional CPUs and GPUs with negligible power consumption.

As for the "quantum blockchain financial system", this is an agreement reached by governments and major banks in Geneva some time ago, aiming to promote a blockchain transaction system secured by quantum encryption technology. In the past, the Bitcoin system was wiped out by the Galactic Federation along with those shady activities on the dark web due to its involvement in financial crimes. Although the rest of the blockchain trading system has improved the regulatory mechanism, it faces the threat of digital currency encryption being cracked due to the development of quantum computers.

The new blockchain system uses a quantum digital signature protocol, and each pair of nodes is connected by a quantum key distribution link, which in principle ensures that the identity of each participant is verified, and makes it impossible for a malicious hacker to tamper with transaction data through brute force attacks, which are discovered the moment the attack is discovered, and the transaction is invalidated by the termination of communication, which can be followed by the police or a miniature missile after a "quick trial", depending on the severity of the crime.

"Well, if I don't have Sister Fennel, I always feel weird. ”

Although the other party found a corner to take a nap after lunch on weekdays, and did not show his presence very strongly, but now after separation, Yuta Tomigashi realized that after two years of getting along, he and others had become accustomed to her existence.

"Quantum communication technology...... Speaking of which, in addition to the quantum key, it seems that there is also a quantum teleportation?"

Although the computer in front of him has a voice recognition function, he is too lazy to check the web page, and he still connects to the database in the mental network. Quantum teleportation is different from quantum keys in that it does not protect information by encrypting data and assigning keys. In the former, the communicating parties share a pair of entangled particles A and B, and one of them measures the particle C with the quantum state to be transmitted and the entangled particle A in its own hand to obtain a new pair of entangled particles, and randomly obtains a set of strings in 00, 01, 10, or 11. The quantum state of C changes the moment it is measured, and the information on it disappears. After the other party receives this set of strings, it performs corresponding operations on the unentangled particle B, so that B collapses into the original state of C, and the quantum state of particle C is transferred. Engineered by informaticians, this quantum teleportation can be used to transmit information.

"I think it's amazing...... But sure enough, the Galaxy Federation still has black technology!"

Some of the technologies of the Galaxy Federation are also based on quantum teleportation, but they can't stand the fact that others have superspace-time technology! Unlike what many people imagine, quantum teleportation itself cannot transmit information faster than the speed of light, and the above-mentioned 2-bit string has to honestly follow the classical channel, and even if the number of degrees of freedom transmitted at one time - commonly known as "bandwidth" - is raised, the transmitted quantum state will not automatically organize particles to form objects at the other end. However, the classical channel of the Galaxy Federation takes hyperspace, and the work of constructing 3-dimensional objects is done instantaneously in high-dimensional space, which is no different from opening and hanging.

The connection between Yuta Tomigashi's ontology and spiritual network on Earth is based on these technologies. The chrono-temporal probes in his brain are responsible for collecting information about the activity of neurons at the cellular and molecular levels, while the quantum activity involving the "soul" – the unique mental structure of an individual – is coupled through quantum teleportation and the soul clones in the mental network.

The body of a certain off-line [wise man] was also teleported to the earth in this way, after all, the Galactic Federation did not set up an institution like a biochemical laboratory on the earth. As for how to get the identity, the other party doesn't seem to want them to know.

"Well, if you think about it, this is just the tip of the iceberg of super civilization. ”

Yuta Tomigashi smiled a little self-deprecatingly. There are still more materials in the Galaxy Federation that have not been opened to them, and the [Wise Man] who has been promoted many times is an incomprehensible form of mind for human beings, and it cannot be ruled out that there are more magical black technologies. However, considering that the actual development history of the Galaxy Federation is not much longer than that of human beings, the development of intelligence and the progress of basic science are one thing, and the accumulation of applied technology is another. At least he didn't find a large facility in the database such as a stargate across the universe.

"Well, then again, it seems like it's been a long time since I've fought against each other...... Do you want to find Du Mu and them to fight a few games?" his mind turned elsewhere, "Uncle Duanshan hasn't been there for a while, but you can go to practice this weekend." ”

……

(Thursday, April 17, 2014, afternoon; California, near Mu's home)

The bright spring light shone on the land, and a path winded and narrowed down a long hill before cutting straight through the woods below. The sunlight passes through the emerald green barriers, and the pavement is dotted with spots of light, and on the sides are tall small white birches, and the trunks are white and the branches are soft.

"Haha, long time no see. ”

Du Mu's body practiced martial arts in the real world, and his soul clone went to the virtual world to greet him and the little bird You Liuhua. Lu Qingyi's body was also practicing, while Xu Mingshan didn't know where he went.

"yes, I've been busy with something else lately. By the way, what about Xu Mingshan?"

"He's fiddling with his python. Because I was going to submit the paper in June and July, I was busy supplementing the experimental data during this time. Du Mu pursed his lips, "By the way, judging from the game, you seem to have the identity of a [Pitch Black Flame Envoy]?"

Yuta Tomigashi's eyelids jumped when he heard this, and then he glared at the little bird You Liuhua fiercely. The latter nodded without any scruples, and said with a serious face:

"Yuta is the inheritor of the power of the [Dark Flame Dragon], and uses [Pitch Black Flame] to fight, and successfully advanced to the [Dark Flame God] Gelzon· Ni· Unsas…… Wow, it hurts!"

He couldn't help but give this girl a hand knife - this kind of shameful black history is better to stay in the seal obediently.

"Since they're all here to fight, why don't you let me see the combat power of the [Pitch Black Flame Envoy]?" Du Mu shook his hands, his fighting spirit was high, "I usually fight against cold weapons, but this time I try the fantasy confrontation, hehe." ”

Tomigashi Yongtai looked at the young grandmaster in front of him in a daze, and he didn't know what to say for a while--which god did I provoke meow, and why did everyone around me have a tendency to be sick in middle school? Could it be that this is the aura of the legendary protagonist?

"How can there be such a good thing without me?" As soon as the words fell, Xu Mingshan's figure appeared among the bushes, "Come on, come on, Imperial City PK, don't die and don't go home." ”

"You beat yours. Lu Qingyi swooped under the tree next to him, his long ponytail raised due to acceleration, covering his face and looking at him unbearably, "Don't get involved with me, I won't participate in the war." ”

"Isn't it the black history of junior high school......" Before Du Mu finished speaking, he was kicked to the ground by the embarrassed girl, "Hiss...... Qingyi tap your hand!"

"Call my sister!"

"Miss Qingyi, I was wrong!"

"Er, two?" "Little Bird You pulled out his umbrella in a row, "I'll fight!"

"Refreshing! I am the Venerable of Time and Space!" Du Mu got up as if he was nothing, his hands formed a complicated rune, the blue light in the left divine pupil appeared, his eyes were as deep as a secluded spring, and his divine power was as vast as a prison, "Heavenly Rank Divine Position, True Body Descends!"

The little bird Yu Liuhua was unwavering under the other party's divine power, the folding umbrella swirled and churned in her hand, and her eyes turned into blazing golden [Evil King's True Eyes], followed by the familiar ritual accompanied by spells and body movements:

"Burst, reality!"

"Break it, nerves!"

“Banishment——This——World！”

Seeing this, Yuta Tomigashi gritted his teeth, and the pitch-black flames surged, and he also chanted:

"Burn, soul!"

"Bloom, Black Lotus!"

"Burn it all—here—the sky!"

Anyway, in the virtual world, it's like playing online games...... Who's afraid of whom!

His casual clothes have been transformed into a black coat, and the little bird You Liuhua has also changed into a gothic dress. Opposite them, Du Mu was dressed in green clothes, his long silver-gray hair was wantonly scattered, and his left eye faintly revealed a strange blue glow, while Xu Mingshan was wearing a white brocade robe, and the fire flickered in his azure starry eyes, and the spiritual power around his body was as round as one, and his momentum was extremely restrained, making it impossible to see the depth.

"Take me a shot!" Du Mu grabbed a spear out of thin air, and his figure rushed towards him in a flash, "Wind and thunder!"

Gusts of wind mixed with blue lightning reached Yuta Tomigashi almost instantly. He felt bad in his heart, only to say that the opponent's attack was really amazingly fast, and instinctively burst out of the pitch-black flames in his body, and at the same time swung his sword to block. Although he hurriedly blocked the attack of wind and thunder, he was still stabbed by Du Mu's shot, and then was blown away by the violent explosion brought by the confrontation.

"This space secret method of shrinking into inches is not bad, right?" Du Mu did not take advantage of the victory to pursue, but suspended in mid-air, "Be careful, my name of [Time and Space Venerable] is not called in vain. ”

Don't you want to take advantage of the skills that you have learned about me beforehand? Yuta Tomigashi has a great fighting spirit in his heart, and he feels like he has returned to the second year of junior high school. Then let you see the [Black Flame Messenger] with all his might!

"Dragon Soul Burning Spell!"

With a flip of the palm of his right hand, a blue-golden flame rose up, turning into two extremely swift fire snakes, attacking Du Mu alternately one after the other. The latter snorted coldly, and the spear drew a circle in midair, and the fire snake was instantly annihilated in the twisted spatial vortex. Immediately afterwards, the opponent's guns were united, and his footsteps flashed in front of him.

"Meteorfall!"

The tip of the spear stabbed straight at Yuta Tomigashi with unparalleled might. He had already taken precautions against this, and at the moment of spatial fluctuations, he cast the "Void Shuttle" to escape, and then threw out a delicate and exquisite black lotus with his backhand, and the terrifying destruction fluctuations firmly locked on Du Mu.

"Eat me a Fire Lotus of Destruction!"

The killing move was dodged, Du Mu was in a state where the old force had just gone and the new force had not been born at the moment, and the divine power in his body could not be condensed instantly, so it stands to reason that he would definitely have to resist this blow. But what Yuta Tomigashi didn't expect was that the blue light of the other party's left eye pupil was sheng, and a blue and faint rainbow light charged up for a moment and shot straight towards the black lotus.

"Cold Domination!"

Tomigashi Yuta watched in amazement as the black lotus was frozen—it was a highly condensed pitch-black flame! However, after Du Mu used his magical powers, he also seemed to consume a lot, so he had to suspend his offensive and calm the divine power in his body.

"If it weren't for the fact that I had this [Xuanbing Divine Pupil], this Fire Lotus Destruction would be in trouble. Du Mu stared at him in mid-air, and the battle intent in his eyes was even worse, "One move will determine the winner, let me see your big move!"

"Good!"

Yuta Tomigashi nodded, and began to brew a pitch-black flame. More and more terrifying fluctuations of magic emanated from him, evaporating all the white clouds in the blue sky.

"Be consumed by the black flames!"

The black fire dragon burst out of his right palm, rising against the storm, roaring and rushing towards Du Mu on the opposite side. The latter threw the spear in his hand, and his hands formed a dazzling sigil, and the time and space around him gradually became fragmented.

"Space freezes! Time stands still!"

As soon as the other party's words fell, Yuta Tomigashi only felt that his body was tight, and his body and the released flame dragon couldn't move. Although time did not completely stand still under his full struggle, his movements became extremely slow, just like the "A Frog Python Asking for Life" by Chiyin Nanamiya, while the little bird on the other side of the battlefield, Yu Liuhua, still maintained a normal speed. After a while, Du Mu's supernatural powers were unlocked, and he also regained his mobility.

"Originally, the three-plate axe had one last move, 'Plane Exile', but it would be too exaggerated to use that one. Du Mu's figure slowly descended to the ground, "Anyway, don't you still have the form of a [Dark Flame God]? ”

How can it be used in front of you! That is the most shameful even in black history!

"By the way, I remember that China has time magic, right?" Yuta Tomigashi turned his head to look away, deliberately changing the subject, "Why don't you use time magic?"

Du Mu rubbed his hands quite embarrassedly, and then pretended to be calm and said, "Ahem, don't be too violent, be elegant...... We generally use time magic in the realm of literature rather than in the realm of martial arts. You can't always think about making big news, can you?"

It didn't take long for the battle between Little Bird You Liuhua and Xu Mingshan to end. The latter opens with the "Void Condensing Sword", and then the two of them each control the missile and the sword array to fight, and finally the little bird Yu Liuhua wins with a forbidden spell.

"It's not bad! There is a ...... from the palace" Lu Qingyi clapped his hands gently, and then realized that something was wrong, "Uh, it was a slip of the tongue just now, I didn't say anything!"

Do I really have some kind of protagonist aura? Yuta Tomigashi was once again speechless.
