Time is a substance.

This concept has been proposed for a long time, but it has never been proven, and it has always been torn between matter and scalar.

Time is often seen as an object that exists independently of anything else, with an endless and even pass. This is in line with Newton's concept of "absolute time", which is also a universally accepted scientific concept of time.

However, as scientific research moves from classical mechanics to quantum mechanics, this basic notion is challenged. Einstein's special theory of relativity states that time cannot exist independently of the universe and its events, and that time can be inhomogeneous.

The most direct proof is that due to the gravitational field, the clock at different altitudes on the earth's surface travels at different speeds, and the higher the altitude, the faster the clock speed, with a difference of about 1.09×10*-16sm. That is, for every 100 meters of elevation, the clock becomes a quarry of a second faster.

Stephen Hawking also mentioned in "A Brief History of Time" that time is not a fixed coordinate, but a substance that surrounds us. It's like three-dimensional space, you can't see it, but it does exist.

Time, space, and energy can be transformed into each other. In quantum theory, the so-called law of conservation of mass and energy is almost wrong, and Einstein's mass-energy equation is the best proof of this.

Time and space are made up of energy. And this energy determines the balance of the universe, and the magnitude of energy is 10 to the 94th power of grams, and if calculated by the mass-energy equation, this energy will be very large to a very terrifying degree......

Thus, the unevenness of time energy leads to the uneven flow of time. That said, it's not impossible to change the time, as long as there is enough energy or speed. As stated in the Superman films, reaching the speed of light can even reverse time.

And Yao Shi Li's kaleidoscope writing wheel eye has such power, the so-called control of time!

In fact, it is a bit of an exaggeration to say that it is in control, at least for the current pharmacist. This is also what he said on purpose, and he was ruthless. Time ninjutsu is even more obscure than space ninjutsu, and the strongest type of ninjutsu that only the six immortals know is so easy to master?

With Yao Shi Li's current strength, he can only speed up or slow down the time in a small area around him, and he can't stop time at all, let alone turn back time......

However, even speeding up or slowing down is already a very unnatural thing for them now.

For example, it causes the time to be uneven in the corners of the five elements of this formation around you. Some fast, some slow...... For example, there is a surplus of cold gold and a shortage of raw wood...... In this way, once the energy is unbalanced, this array will naturally break......

As expected, the surrounding time began to be noticeably distorted.

"What...... What the? "Ruthless didn't seem to expect such a situation, this formation that was already ten out of ten is actually destroyed by the unexpected thing of time......

Once the formation starts, it cannot be stopped, and it cannot be reversed. The more powerful the formation, the more so. The Heaven and Earth Xuanhuang Array can be regarded as very powerful in the small formation, so it is very dangerous once it is interrupted. And...... The energy of the five elements is incompatible, and the most likely result is...... Explode......

I felt that the energy fluctuations around me began to boil violently like water entering hot oil, and even faint black smoke appeared.

"Not good!" Ruthless had just called out, and there was already a loud boom. He was now a vitrified body, and the shock was enough to turn him into powder.

The wave of the explosion rippled out, uprooting some of the surrounding trees, and some even turning them into pieces.

Yakushi sat on the ground in the distance, gasping for air. At this point, his image is no longer associated with elegance.

His face was dusty, his clothes were in tatters, and even the pair of black, shiny wings behind him were shattered and broken.

"Did you escape...... pharmacist wiped the blood and dust from the corners of his mouth lightly. Looking at the messy scene in front of him, he said lightly.

"It seems...... It's a draw again...... It's a pity......" Yakushi Li smiled faintly and slowly stood up.

The body finally began to regain consciousness little by little, and if it weren't for the fact that the wings could be moved just now, Yao Shili might have been blown up even more miserably. Although Yakushi Li used a kaleidoscope to slow down the passage of time around him, so that he had enough time to get out of it, but his body was uncontrollable, and he exploded before he could fly halfway, and he could only hold himself with his wings, and the result was like this.

"However, I didn't expect that guy to use a thousand miles of magic to walk...... It seems that he has probably been back to recuperate for a long time...... Ha, I'm at my limit......" Yakushi sat on the ground weakly, and the eternal kaleidoscope had been taken back by him. If the pupil power is consumed too much, although the eyesight will not deteriorate again, fatigue is inevitable, so you have to take a good rest.

Although the time ninjutsu thing sounds like a gimmick, it's quite a big thing, although it's against the sky, but it's also quite chicken. The consumption of pupil power is so huge that Amurasu can't match, and it's shorter. It's only about 10 seconds.

Of course, this is 10 seconds for others, and for Yao Shi Li, it can be about 60 seconds.

"This bastard......" Yao Shi Li scolded secretly, and slowly walked forward, his last words coming from the air with a faint smell of burning.

"It's really hard to find a good dry cleaner in a place like this...... The next time we meet, let him pay the bill for the laundry by the way......"

At this time. Konoha.

It's been a day since Naruto came back, and after sitting on the Hokage Rock for a while, he immediately ran into the former powerhouses. Everyone is very face-saving to listen to Naruto's flawed boasting but not exposing it, but when Naruto learned that he was still a middle ninja and the others were almost upper ninjas, in addition to being slightly disappointed at first, he was immediately full of fighting spirit.

But within a few days of peace, Naruto suddenly felt a strong sense of unease.

Although Naruto seems to have a lot of nerves, his instincts are very sensitive. Almost beastly sensitive. Everyone else was envious, but in fact, Naruto wanted to shout, "This is all forced!" ”

This is also one of Yakushi's masterpieces, and watching out for Yakushi's bad behavior all day long, Naruto's intuitive accuracy has risen to a terrifying level. Even if he put aside the Nine-Tails, his instincts could be enough to be a beast.

Sure enough, on this day, as if a storm was coming, the entire Konoha and even the whole world were filled with a depressing atmosphere. Naruto's beastly instincts told him that a great calamity was coming.

Immediately, Naruto was called into the office by Tsunade.
