"In the universe, because the size of the planet and the mass are not the same, therefore, time and space will also have some changes, usually, in the same star field, the time of the planet is basically synchronized, the difference is only that day and night will change because of the size of the planet gravity and sunshine time, but, in general, it will not affect human activities, for example, some colonial planets near the Sahara Star are like this, you go for a few days, after returning to the Sahara Star, there will not be too much time dislocation. However, in other colonial star fields, there will be a big change, for example, if you go on vacation to another star field for three days and return to the Sahara star field, it is likely to be years or even decades later......"

"Eun, keep going." Wang Du was overjoyed, this was the first time he came into contact with the explanation of the relationship between time and space.

"In the universe, there are different time and space, under normal circumstances, if you travel indiscriminately, you will fall into the chaos of time and space, for example, grandparents and grandchildren are the same age, this kind of chaos of time and space may not be anything for the traveler, at most it is an ethical problem, but it will seriously affect the normal development of the whole society, after all, a human being who comes to the future or comes from the past will always cause social turmoil, and even some careerists will try to tamper with the future and so on......"

"So what to do?" Wang Fool remembered that he had completely changed his life after crossing sixty days, and hurriedly asked.

"In the universe, there are parallel spaces, space barriers, timelines, and black holes that can freeze time and space forever in an instant...... After all, many things cannot be experienced in person, and can only rely on the optical brain calculation and the speculation of scientists, and some of the things that have been confirmed are not said, and those that cannot be confirmed are still being studied, such as black holes that can freeze time and space, which are still only doubtful......"

"Let's talk about crossing the machine in time!" Wang is not a scientist, and he is not very interested in those messy time and space, and he is most concerned about his timely travel machine.

"The timely travel machine is the greatest invention of mankind so far, it uses the principle of different timelines, so that all human beings who travel through live in their own time and space, even if it is a long distance, the error is a few minutes, or even negligible." Yue Yue is a taciturn person, but when he mentions his profession, his expression is extremely wise and natural, and he has the temperament of a scholar.

"Any planet can be used?"

"Not any one planet, it's any one person."

"Anyone?" Wang Du was a little incomprehensible.

"When the traveler enters, it will automatically send the traveler to the moment of departure, so that the traveler will not affect the life of the human beings in the original place of residence. Of course, there will be some side effects of this crossing, and it is generally not used lightly. ”

"What side effects?"

"For example, if you live on a planet for many years and then return to where you lived, that is, you have not lost your time, but in fact, you have spent a few years, and your lifespan has actually been shortened by ......"

"Oh, I see, time and space are infinite, but human life is limited, it is impossible to live on one planet for decades and then live on another planet for decades, in fact, no matter where you live, you will consume the same life."

"Yes, this will have a very serious consequence, when you come back from a few minutes away, you will already look old, because you have consumed your life in another dimension."

"Hehe, that's fair, otherwise, if you don't age, human beings are equivalent to having endless life."

"Hmm. In fact, at the beginning, scientists did not want to use the timely travel machine to maintain the balance of the timeline, but wanted to let human beings enjoy life in different spaces, and later they realized that it is not advisable to use the method of time and space migration to prolong life, but it makes people unacceptable to human ethics. ”

"Why can't it be accepted?"

"It's very simple, your couple goes out on a trip in time, plays for decades and comes back to become an old woman, that is, to become a strict aging woman in a few minutes, can you accept it?"

"I can't accept it."

A wry smile appeared at the corner of Wang Fool's mouth, he remembered the white-haired girl and the scattered fairy Xiaoqian, they had been haunted by the things they had been waiting for hundreds of years, if they suddenly appeared in front of them as an old dragon clock, or if they appeared in front of them as an old woman, no one could accept it. Fortunately, although it is hundreds of years, Wang Du's time on the earth is very short, and the white-haired female who has spent hundreds of years is always beautiful, and can retreat and cultivate, otherwise, she will really go crazy.

"Therefore, except for some scientists and adventurers, ordinary people will not use the timely crossing machine, of course, once encountering irreversible danger, timely crossing machine will become the last choice, however, the danger should not be underestimated."

"And dangerous?"

"Yes, time travel itself is very dangerous, ordinary people simply cannot withstand the magnetic field formed by quantum, once the human body has formed a molecular structure, it is likely that it will never be able to recover its original form, and the form of the molecular structure will disappear in the space-time tunnel."

"Oh......"

Wang Du didn't have any feelings about the danger of crossing the plane in time, after all, he not only had a strong physique, but also a cultivator in the Yuan Infant Stage.

At this moment, Wang Du is racking his brains to think about how to get a timely crossing machine. With the timely travel machine, Wang Du can adjust the timeline of the earth and the other space to synchronization, even if it is not completely synchronized, it should not be hundreds of years at every turn.

It's obviously not easy to get one to cross in time.

It can be inferred from the words of the introduction of Yue Yue that the timely crossing machine is not a civilian product, and the government has extremely strict control in order to avoid being used by lawbreakers, and the timely crossing machine is very large, and it can be felt from the time of operation that it not only occupies a huge space, but also needs huge energy support.

Now even if the Sahara Star authorities send Wang Fool a timely travel machine, Wang Fool has no way to use it.

Although the space of Wang Fool's space ring is large, it is not enough to fit a huge timely crossing machine, not to mention, the timely crossing machine also needs countless auxiliary equipment, such as generators and the like.

Suddenly, Wang Du was whimsical, what if he used the Sahara Star as a transit point to go to another space?

……

"Hello Mr. Wang, the chairman of the board of directors, please come over." Just when Wang was thinking nonsense, the manager walked over.

"Ah...... Good. ”

"Hello Mr. Wang, we just held a board meeting, and we have always agreed that you will test the performance of the Black Yao Mecha-B6 on site, but we have one request." The chairman on the holographic screen looked a little excited.

"Say."

"We will arrange a large number of reporters and staff to accompany Mr. Wang, in addition to ensuring Mr. Wang's safety, but also to record Mr. Wang's battle scene as our Heiyao company's promotional materials, I don't know Mr. Wang's ......"

"Okay, I agree!"

"Since Mr. Wang agrees, please go to the Pengcheng No. 1 spacecraft base, our staff is preparing, if it is a qiē shun lì, in an hour and a half, we can set off, the cosmic worm outbreak point in front of the Sahara star coordinate 17." The chairman was a little excited.

"Dear sir, I also have a request, the environment we test must be the most brutal and tragic combat environment, only in this way can we be convincing."

"This ......"

"Chairman, I don't want anyone to think we're cheating! I think the chairman should understand what I mean. Wang Fool's deep gaze was fixed on the chairman on the holographic screen.

"Okay." The chairman gritted his teeth and seemed to have made a very important determination.

"Trust me!" A smile appeared on the corner of Wang Du's mouth.

"I believe in you." The chairman nodded heavily, and there was a hint of fanaticism in his steady eyes.

……

When Wang Fool and his entourage walked out of the exhibition hall of Heiyao Company, they found that the entire equipment building was already overcrowded, and there were black and black heads everywhere.

With the assistance of the Yunding tribe and the staff of the equipment building, the group came out of the equipment building and saw a silver-gray car quietly parked at the door, the vehicle was very long, estimated to be about 20 meters, two meters high, and about three meters high.

On both sides of the car, there stood several armed bodyguards in uniform, and their straight chests made people feel an inexplicable solemnity.

In addition to the heavily armed bodyguards, around the car, there were some military police wearing standard combat armor, all of them stepping on hoverboards, all with solemn expressions.

"Hovering RV!"

Looking at the car, Meng Qiang's eyes were about to fall to the ground. In fact, it was not only Meng Qiang who was shocked, but also the vulture Zhao and Yue Yue Xinyue, who had seen the world, all had a dull expression.

"Questions?" Wang Fool asked.

"This is the hovering car of the city lord of Pengcheng."

"Pengcheng City Lord?" Wang Stupid was also a little surprised.

"Yes, he is also the richest man in Pengcheng." Vulture Zhao shook in his throat and kept swallowing.

"A warm welcome to our great heroes!" Just when everyone was shocked, the door of the hovering car suddenly opened silently, and a middle-aged man in a black dress with fair skin came out of it, strode in front of Wang Du, and made a warm hug posture.

"You are the city lord of Pengcheng?" Wang Stupid stared at the middle-aged man and did not open his hands.

"Yes, Dear Mr. Wang, I am Qiu Xingguang, the city lord of Pengcheng." The middle-aged man didn't get a response from Wang Stupid, his body stiffened, and he had an embarrassed expression.

Qiu Xingguang ...... Good name. Wang stupidly laughed, opened his arms, and hugged the middle-aged man fiercely, which was regarded as giving him a step down.

"I am entrusted by the chairman of Heiyao Company to arrange Mr. Wang's trip for this mecha test."

"It turned out to be the arrangement of Heiyao Company, I thought I was flattered to be received by City Lord Qiu!" Wang smirked.

"Ah...... Mr. Wang's words are serious, I am a loyal fan of Mr. Wang, and I feel honored to meet Mr. Wang. ”
