Nobita soon put this "spherical", "battleship-type base artificial star" place.

Give him a full introduction.

It is said that this was built by Zheng Ying's father, Xingxuan, hence the name Xingxuan Base.

It is also the only place among the Seven Elders that only Tu Daxiong knows.

"Aren't you afraid that after I leave, I will return to Earth and tell my chief to talk about Mr. Xiaoping?" Changfeng said with a smile.

Tu Daxiong glared: "That's right, then I should kill my mouth first!" ”

Changfeng was stunned for a moment, and Tu Nobita haha: "Teasing you, silly boy." ”

He said that without Nobita's order, this artificial star would revolve around the earth at ultra-high speed every day, and it would not be detected not only by the earth, but also by other high-tech civilizations in outer space.

If it can be detected, it is an extradimensional civilization.

"Because our base is the existence of four-dimensional space-time!" Tu Nobita said very seriously.

Changfeng was nervous, and he felt funny.

"Four-dimensional? Length, width and height, plus timeline? ”

Tu Daxiong shook his head: "You don't study this, you don't understand it, in the top-secret scientific field of the third base, the dimension of time and space, time, is not a dimension, to the five-dimensional space-time, the three-dimensional world of the earth where we are located, where time can be visualized as an object, you can see, as long as in the five-dimensional space-time, your 'vision' ability is good enough, you can see what will happen to the earth for many years in the future." But now, we are still in the lower dimension of the five-dimensional space-time, in the words of young people, it is the dimensional wall! And Zheng Ying, called it a 'barrier'! ”

"Barriers?"

"That's right!"

Tu Daxiong handed a small notebook to Changfeng, and when he opened it, it looked like a leather notebook on the outside, and there was indeed an e-book inside.

Statistically similar to the undulation line.

The years are clearly marked on the top, with trough lines and peak lines.

After a few casual searches, I found something related to the so-called "barrier".

The barrier is divided into several meanings here, one is the limit of humanity, one is the limit of the universe, and the other is the limit of life.

Life includes human beings, but human beings are not absolute life in the universe.

In the limits of human beings, IQ, cognition, and potential, these three barriers are the things that bind human beings from reaching the high-level civilization of life in the universe.

If there is a breakthrough, then such a person is very powerful in human beings, but in the cosmic life cluster, it may just be an ordinary existence.

And the limit of the universe, one of which is "dimension"!

Crossing dimensions is equivalent to going to a whole new world, where everything is new.

If you go back and look at the chronological peak, there is a high peak, which is about tens of thousands of years after the earth.

Tu Nobita looked at him surprisingly, and seemed to be a little ignorant, so he pointed to the peak and told Changfeng: "We human beings, sooner or later, we will have to migrate to the interstellar world!" ”

Changfeng frowned: "Is something wrong?" ”

"It's just that there are too many bastards like Lu Xian, so that the only earth world we can survive, our home, during this period, will be self-repairing cycle era, killing everyone on the earth!"

"Anti-...... Mankind? "The long wind felt a chill down my spine.

Tu Nobita smiled bitterly: "Self-repair, it's not who will kill us, it's the defense of the earth itself!" Whether it's the greenhouse effect, or the pollution caused by war and industry, you can anthropomorphize the earth, liken it to a sentimental or stubborn child. At the moment when it was unhappy, none of the creatures in it had good fruit to eat! ”

"How?"

"The earth will turn its surface into a sea of fire and then an ice age at a cost that human beings cannot bear, and after tens of thousands or millions of years, all the creatures on the earth will die, and there will be new life gradually appearing and new births! Start with Phanerozoic! Start with the bottom creatures, trilobites, aqua coelenterates, plankton, and even the densest bacterial microbes! Evolution little by little, waiting for another reincarnation, a new human evolution. ”

Nobita Tu sat next to a machine: "At that time, no one will remember our human civilization in this cycle!" Because it's erased! ”

"Are you saying that the earth cycles through epochs at certain intervals, when the deadline is reached? In this case, is it possible that we are not the first human beings to circulate on Earth?! ”

"Does Wu Bo know?" Tu Nobita suddenly mentioned another Seven Elders.

Changfeng nodded.

"Under his command, there is a sea base called the Black Light Ship! Chu Liang, the current captain of that ship, has a power that is even more terrifying than that of the Lin guards! He is the human being three cycles ago! If you use age to count, you will feel extremely, because his age, so far, estimated, is 10 to the 9th power, plus three times his age! Is that...... 2.7 billion years old? Haha, it sounds like a fairy. ”

Changfeng took two steps back, smiled bitterly, and grinned in disbelief: "You...... Forgot to take your medicine, right? ”

Nobita grabbed a discarded iron pipe directly from the ground, grabbed it with one hand, and waved it up and down with one index finger of the other, easily cutting the iron pipe into two sections!

Then he handed it to Changfeng: "Check it!" ”

Changfeng didn't dare to breathe, took the iron pipe, and flicked it a few times with his fingers, it was really a steel pipe, very strong.

He also clenched his hands and bent them a few times, back and forth several times, but he didn't break it, but the steel pipe was deformed, and it was a little hot.

Tu Daxiong said with a smile: "You just folded the steel pipe back and forth and burned red, and you won't cut it off as easily as I just now." ”

"What's going on?" Changfeng became excited.

Tu Daxiong pointed to the top of his head, Changfeng looked up, and what he saw was just the boundless, vast sea of stars in the universe!

"This is a method that Chu Liang told me, extradimensional power, so far, I have only broken through one of the three major barriers of the human race, a small part of the power of potential!" Tu Daxiong walked over and stretched out his hand to him: "Check it, what is the difference with yours, or other people's hands?" ”

Changfeng grabbed Tu Daxiong's hand and pouted: "Two big men, although it's very bad to pull and pull, but I'm here for research, I don't mean anything else!" ”

"Hmph, just look at it, twisting and pinching is not like your mountain man Changfeng!"

Sure enough, Changfeng found that Tu Daxiong's hand had undergone inhuman changes!

Non-human, which means that normal people cannot have such ...... Such a sturdy pair of hands.

It can be said that Tu Daxiong's hand can already beat the Seven Divine Soldiers, he is just an ordinary person, one of the seven elders of the third base, an old man who is close to the sixtieth year!

But Nobita's hand, judging by Changfeng's ability, in terms of the density of human cells, this is almost metal-grade skin!

And on every palm and skin texture, the thorn-like sharp dandruff is clearly visible!

It seemed that Tu Daxiong moved, and Changfeng felt that although his hand was like a rusty blunt knife, it could become extremely sharp in an instant.

Not far away, a guard ran from the ceiling of the hallway, and this mode of walking headfirst down here, Changfeng had begun to get used to it.

It's like a space capsule, gravity, and the gravitational pull of the earth, which is completely unsearchable, but the gravitational force that supports the normal activities of human beings here still exists, which is a bit exaggerated.

He handed Changfeng a telescope-like device.

Let him wear it on his head.

Through this instrument, Changfeng can clearly see the body information of Nobita in front of him.

For example, the proportion of metal elements in his body has exceeded the proportion of the human body by dozens of times!

Assuming that Tu Daxiong weighs only one hundred and twenty catties, then there are ninety catties on his body, all of which are made of metal substances that are harder than diamonds, just like ...... As mentioned in a certain movie, alien metal lifeforms are the same!
