Positive and negative are a fundamental concept in mathematics and physics.

Negative mass matter, unlike antimatter, because antimatter, the charge carried by elementary particles and the cosmic charge, collide with positive matter, and the mass will become energy. Antimatter also falls into the category of positive mass.

And negative mass is a mass that is "lighter" than zero mass!

Scratching his head, Jiayu can't imagine what a concept it is to have a mass of matter less than zero!

What a form!

What a pattern!

Anyway, the nascent elementary particles are less than zero!

Only in this "Dirac Sea space", where there is no matter and no elementary particles, can he sensitively discover that the mass of the newborn particles is indeed negative!

Not a negative number in the mathematical sense, but really lighter than zero!

At the beginning, Jiayu made a mistake in the estimation.

The mass is equivalent to the mass of elementary particles, electrons, but below zero, to be precise, it should be minus trillions billions of billions...... Two-hundredths of a gram.

Even though Jiayu was instilled with almost endless physics literature by Nebula, he was also confused about the "negative mass particles", and he didn't know what this thing was for!

Soon, he discovered that the mass of the negative-mass particles he had "created" began to increase in the negative direction out of nothing!

With the injection of the energy of the original starlight, there are more and more negative mass particles, and the effect of anti-gravity begins to become prominent, and there is a tendency to transform into negative mass matter!

Maybe after a while, Jiayu will be able to produce a negative mass "brick", on the surface of the earth, the brick is out of the hands of the hands, and will not fall directly to the ground, but swish, flying towards the universe, away from the direction of the sun, towards the void outside the galaxy......

Jiayu's consciousness "looked" at the indistinguishable mass of "negative mass" atoms in the huge star ring, and his mind was like a wild horse, galloping wildly.

"Negative mass? Anti-gravity? Virtual particles? It's kind of touching when you think about it! ”

Jiayu has no heart and no lungs.

Negative mass is a new toy for him, and he may be able to exert unimaginable power at some point!

He was having no heart or lungs, but suddenly discovered that a mass of negative particles claiming to be the universe came into existence out of nothing, producing hundreds of billions of dollars...... After sevenths of a gram, the rate of proliferation is slowed down.

Jiayu was shocked, he knew that his current self should be regarded as having evolved to the realm of high-energy god level again.

Limited to its own level of evolution, negative mass particles can only produce so many quantities, in the microscopic vacuum, tens of billions of negative mass atoms composed of an extremely tiny crystal gem, attracting inexplicable energy from outside the universe.

In a "negative mass gemstone", the mass of its basic atoms is negative, and even the energy in it is negative.

Jiayu muttered to himself, "Negative mass, negative energy, not antimatter!" Antimatter is still a kind of matter, after all, it is still a mass above zero, and a tiny weight can be measured in this universe, but negative mass and negative energy are different, smaller than no mass, lower than the limit of this universe! This paragraph is the key point, and the ...... to be tested is to be examined"

In the "Dirac Sea" space, Jiayu, who existed like the Great Demon King of Smoke Cloud, was finally satisfied, what is the use of negative quality gems, and he was slowly pondering in the future, and now he thought, is it okay to ask the Dirac Sea space, what peerless martial arts can be taught, the ancient lost swordsmanship?

Every time, I rely on lasers to create quantum black holes, which is not gorgeous enough!

Jiayu asked a question to the power that existed in a certain Kunlun void in space.

The star ring vibrated and transformed Jiayu's thinking into some kind of high-dimensional language.

"Hey, immortals, do you have any peerless martial arts?"

Then, he found that the star rings conjured up in his brain, the microscopic gems composed of negative mass atoms, were inconspicuously earthquaked!

Then, Jiayu is messy!

In an instant, he was kicked out of the Dirac Sea space and returned to his original body!

…………

Jia Yuleng returned to his body, his own brain, he still couldn't believe it!

Stupid, confused.

"I, did I say something wrong? Why did you kick me out? I'm not prepared at all...... I'm recruiting you, messing with you? ”

Jiayu was blasted out of the spherical space of the Dirac Sea, the land of inheritance, and he looked at the ruins of the ancient city that had become bright in confusion, and he saw that everyone here was immersed in the experience of ancient inheritance, and he was actually the first person to end the inheritance and wake up.

Jiayu couldn't complain, in the Grave Keeper Organization, he was the last to enter the Land of Inheritance, but now he was the first to be "kicked" out of the Land of Inheritance......

"Am I really a scrap of wood? Others still look like they're studying hard, but I'm done? ”

Then, he found that he was in a very awkward state, and something was wrong.

After returning to his body, Jiayu turned his head to look and found an acquaintance.

"Huh? Wang Jin? When did you show up? Wait, why pull a wire out of your head! Ahh ”

Jiayu "See", the mini version, the digital Wang Jin, like pulling out the charging power supply, snapped, and "pulled" a two-phase plug from his head!

It's like there's a socket in my head......

Jiayu was crazy, he wanted to roar, "For Mao! Have a socket in my head for hair? It's not a three-hole socket, it's a two-hole socket, it's too low-end, it's not safe......"

No matter how Jiayu shouted, Wang Jin ignored it, ignored it, pulled the huge long cable that he didn't know where it came from, and flew quickly into the distance.

Then two more virtual intelligent beings, Chubby White and a female ghost, appeared, flying out of the distant hadron planet.

Only then did Jiayu discover that the huge planet where the hadron equipment space was located had actually appeared!

He looked at the three digital creatures of different shapes with a bewildered expression, landing on the side of the planet fragment and pyramid, standing in a triangle, and then, the three digital creatures began to do it......

Something very strange happened? Jiayu's eyes widened!

Between heaven and earth, the fragments of the planet where the hadron equipment system is located really appear in the three-dimensional world.

In the Kunlun ruins, all the expedition members turned a blind eye and looked at the silver ball of light in the center in a daze.

On the miniature planetary fragments, an old "person" is slowly flying out of the database of this galaxy cluster, that is, the top of the pyramid!

Jiayu was completely stunned.

Under the guidance of the interstellar road sign paved with black light bands, the miniature super-civilization intelligent body, Jiayu's "mentor" - Nebula, is flying towards the magnificent and broken alien space passage of the sky!

Jiayu can even see one of Nebula's starry spiral arms, and greet Jiayu like a twitch!

"I'll go, when did this uncle sneak from the edge of the universe to squat in Wang Jin's ...... No, there are cats in my territory, why don't I know? ”

Jiayu desperately recalled, he didn't have a clue at all!

It was only then that he felt all this, and there seemed to be some sense of disobedience, which was very awkward.

A flash of inspiration flashed through his mind, "Huh? Wrong...... Their movements are like a movie playing backwards, huh? ”

…………

Indeed, in the "sacrifice" ritual of "expelling" the Nebula God, whether it is the action of the three digital virtual beings, or the law of cause and effect of the whole world, Jiayu thought about it, it is indeed very weird!

In a normal movie, people walk forward and move very smoothly, but in a reversed movie, people don't look behind them, and they retreat step by step, and the speed is still very fast! Just a while, Wang Jin, Fat Bai, and the female ghost that Jiayu had never seen before, all had some dancing movements in the process, the "prayer" posture of the three digital lives, the gestures and manners of each "person", all of which were a sense of dislocation in time lapse!

"Oh my God! Have I turned back my time? Alas, no, no, no, don't you say...... The Nebula God is not hidden in my watch, but has just been summoned by Wang Jin and a few of them from another dimension? ”

Jiayu was still confused, things were so weird, they were so irregular, but he knew that his guess was right.

Step back in time!

At this time, Jiayu can no longer control himself!

Time is gradually speeding backwards! At the beginning, the speed of time rewind was not fast, and many details that had just happened could still be recalled by Jiayu.

He was like watching a movie that played from the end to the beginning, and the familiar plot was full of awkward feelings when it was played from the end to the beginning, and many things were almost unrecognizable!

He saw that he led the students of the Grave Keeper Organization to fight against the seven high-powered divine skill Source Orcs, and beat these powerful monsters from death, to residual blood, and from residual blood to full blood, and then, there was a scene, several people spit out the potion intact, and received the desperate medicine into their bags, and they returned to become pure human evolutionaries!

Jiayu wants to stop time and change the world at this moment, he is already a real god-level, at this time, he is sure that he will launch a super energy destruction laser comparable to the energy of a stellar explosion, and easily vaporize these god-level gasification! Even if at this time, he broke 7 desperate potions, he felt that with his own ability, it was still relatively simple.

However, time goes back and can't stop!

Then, he saw that his sword was taken back from Mr. Lu's waist, and his body was broken in two, and it was restored to its original state!

Further on, no one on the battlefield could have predicted that Mars would hit the Earth with an unprecedented explosion!

Almost instantly, the two colliding Vulcan bullets separated completely unscathed, one disappeared in an instant, and the other returned to Liu Moxi's hands at high speed.

As soon as the picture turned, time returned to earlier, Jiayu used the "Light Speed Sword" to cut Wang Yi from minced meat into a whole person at high speed......

The two brothers lived, Catherine and her brother Kress ran backwards towards the park, and Jiayu flew back to the tower from the ground with a thud.

The rate of time rewind is getting faster and faster, and the image gradually distorts as it rewinds, as if the details become blurrier as time goes on, the farther away he is from the key point where he started the time rewind.

He regressed from the eerie multiverse, put down the concentrated cherished plant specimens, and flew backwards out of the fantasy space.

In the asteroid belt, Jiayu led people to explore, and with one hand, a huge ancient Kunlun civilization mining ship was completely released!

As soon as the picture turned, Jiayu first entered Kunlun, leading Liu Moxi and Yang Fan to rummage for garbage everywhere in the cultural relics collection site.

The rubble turned back into the building, forming a crumbling Alien Temple! The powder floating in the sky turned into dried flowers.

Time is moving backwards, and the world is a strange place.
