Alke was slightly confused and said: "Huh? Didn't Enrika tell you that the Holy Tower is a place for truth-seeking, the most sacred place for our Yago clan, and a place for discussion."

He raised his hand and pointed upward, and continued: "The sixth floor of the Tower of Truth contains countless classics. Only great wisdom or great sages of our clan can enter. On the first to fifth floors, you will encounter five guardians in turn.

Gatekeeper, as long as your answer satisfies the gatekeeper, you will be qualified to enter the next level."

"Wait a minute? Our relationship is Wenbi?" Nian Yubai was still a little unable to react.

Alke smiled and said directly: "My question is, why can't everything in the world escape the shackles of the earth? Leaves fall back to their roots, flowers fall into mud, what kind of laws are at work here?"

Nian Yubai and Dong Su stared at each other, completely confused.

He coughed twice, forced out a smile and said, "Can we discuss it and change the problem?"

Alke still maintained his impeccable smile: "If you choose to give up, please close the door when you leave. Thank you."

Nian Yubai smiled bitterly and said: "Isn't this a normal thing? What's there to ask? Can't you ask something meaningful?"

Alke smiled and said: "This is the truth we are looking for, it has nothing to do with meaning. In other words, what do you think is meaningful?"

Nian Yubai's head was three inches tall, and he felt completely unable to communicate.

Yu Ling breathed a sigh of relief. Fortunately, the question asked by the other party was quite routine. At least any junior high school student from the earth could talk confidently. Even if he was not good at studying, he could easily give the answer.

Thanks Newton.

"Because the world has universal gravity, nothing can stay in the air for a long time. Even if it is thrown up forcibly, it will fall down on its own."

"Gravity? It's an interesting statement. Can you explain it to me in detail?" Alke nodded.

Yu Ling recalled some distant knowledge, and then said: "There is interaction between any objects. They attract each other through the force in the direction of the center line. The greater the mass of the two objects, the stronger this mutual attraction."

The bigger they are and the farther away they are, the smaller the attraction will be. And we live on this land, and the mass is so small that it is negligible compared to the mass of the planet under our feet, so most of the objects on the planet are

It’s impossible to escape the attraction of the planet.”

Nian Yubai and Nian Yubai had no idea what he was talking about.

Only Alke opposite showed an excited expression, patted his head and said: "Ah, your statement is very similar to that of the great sage Mo Ling. At that time, several great sages were arguing over this issue, although I have always felt that Mo Ling

Sage Zero is right, but he can't find any evidence to prove it, well... your thinking is very clear when you say this, and it's very convincing even if there is no evidence."

"However, I still have a few questions I want to discuss with you. Since any object has a tendency to attract each other, why are we not affected by each other?" Alke continued to ask.

"Of course there is a gravitational force between any of us, but if the mass does not reach a certain level, this gravitational force is very small and the impact can be ignored. And the mass is as large as the planets, and the gravitational force between them is subject to

distance, if they are close to each other, they will form an orbit around the constant

The star rotates, and the satellite rotates around the planet, one level at a time, but if the distance is far, the two sides still do not interfere with each other. This is the rule of the universe. Of course, what I say may be a bit simplistic, and there are also centrifugal force and

Centripetal force and other factors, gravity is just one of countless basic rules."

Alke said embarrassedly: "I was so excited just now that I forgot that you said that gravity is directly proportional to mass."

"To be precise, it is proportional to the product of the masses of the two objects."

"Well, then why are you human cultivators able to escape gravity after cultivating to a certain level?"

"I haven't studied this issue in depth... but gravitation is also a force, and its direction always points to the center of the sphere, so if we give objects an opposite force, we can make them leave the earth and fly into the air for a short time. And the cultivator

What they do is to prolong the process as much as possible. During the marrow cleansing period, the warrior cuts the menstrual passages and cleanses the marrow to make the inside and outside of the body transparent and eliminate impurities, so as to achieve the unity of nature and man.

In this state, they change their physique and use their physical body to resist the enveloping force of gravity. In the same way, soul masters use their soul power to resist gravity. Transformation cultivators use their spiritual power. There must always be an opposite force to enable them to stay.

In the air. But if they don’t cultivate to this level, their strength will not be enough to free them from the shackles of gravity. This is a question of quantitative change causing qualitative change."

Alke nodded thoughtfully: "Last question, what produces the universal gravitation you call? What is its essence?"

Yu Ling couldn't help but was slightly startled. Although he got a good deal with the wisdom of earth scientists, it turned out that the Yago people were not so stupid and easy to fool. He was just a young man in front of him.

The essential problem.

Forgive him for his limited knowledge. This problem is obviously beyond his ability. If it were replaced by a master of science, it might be similar.

"I don't know about this. The cause of gravity should be related to the magnetic field force and the spin motion of charged particles. Its essence may be the depression of space. I don't have a deep understanding of what is going on." Yu Ling said truthfully.

.

Alke couldn't help but his eyes lit up when he heard the two new terms, but he opened his mouth and finally said with some regret: "I have asked too many questions, and I can't waste your time anymore. You can come to me often when you are free in the future."

Let’s discuss it, now I’ll send you to the second floor.”

The light spots in front of them reflected like an ocean. When the three subconsciously closed their eyes and opened them again, they were in another silent space. There were also many scattered light spots here, but compared to the infinity on the first floor, the eyes seemed sparse.

A lot.

A blue light point fell from the sky and turned into a middle-aged man. He was sitting at the table and said with a smile on his face: "Hello, I am Cullan Weed. I am very happy to meet the distinguished guests of the human race."

"Hello, Mr. Wade." Yu Ling also returned the greeting.

Nian Yubai finally came to his senses and whispered: "Aling, what on earth were you talking about just now? Why do I know the meaning of every word you say, but I can't understand them when they are connected together?"

Dongmo also raised his head and said with admiration: "Brother Yu is so awesome. Although I don't understand what you are talking about, I just feel that you are awesome."

... Is it really necessary to be proud of the common sense that all middle school students know?

Yu Ling could only be speechless.

Kurlan smiled and said: "My question is, do you think the future can be predicted?"

"There's no fixed answer to this, right?" Yu Ling looked at him.

"That's right, it's not so much a question as it is a discussion. Six of the nine great sages of our Yago tribe tried to predict the future, and the last great sage Mo Ling even left a sixteen-character prophecy.

Words: The absolute darkness seizes the soul, the ice melts and the snow melts, the dark element reappears, the snow world is unified, and now we are all

I don’t know if it will come true. Sometimes I can’t help but wonder, should we predict the future? If we know a given outcome but cannot change it, then maybe it’s better not to know it from the beginning.” Kuhl
