"It's safe here for a while, and he won't be in the school building. Pen Fun Pavilion wWw. ｂiquge。 info "Xi Yue is holding an apple out of nowhere, playing with it in his hand, and his words always reveal a confidence for no reason.

But Tang Li was not infected by this groundless self-confidence, she cautiously stared out the window, observing the man's movements, and the "∫" in her eyes never stopped flickering, calculating all kinds of information at high speed.

Xiyue looked at Tang Li with a vigilant look, and felt very interesting, in his opinion, the man outside the window did not pose any threat, "Do you know what the nature of gravity is?"

Tang Li didn't pay attention to Xiyue's question, she pretended not to hear it, and continued to use calculus to calculate something.

Seeing that Tang Li ignored him, Xiyue did not express any unhappiness, he continued to speak to himself, "The so-called gravitational force is the mutual attraction caused by mass between any two objects, this attraction can be calculated by mathematical formulas, gravity is equal to the product of the mass of two objects divided by the square of the distance between the two, it should be so, but on our earth, there is something called the gravitational constant. ”

"Gravitational constant?" Tang Li∫'s eyes flashed continuously, and he quickly calculated the result, "Indeed, there is indeed something missing in your previous formula. ”

"f=gm1m2/r?,f replaces gravitational force, m1m2 refers to the mass of two objects, r represents the distance between the two, g is the gravitational constant, although I don't know what principle it is based on, but from everything that happened before, the man outside the window should be free to modify the gravitational constant between objects, which you will feel immediately. As Xi Yue's words fell, a slight vibration suddenly came from under the feet of the two.

Tang Li, who has the ability to calculus, quickly understood the meaning of Xiyue's words, but this still did not change the status quo faced by the two, the vibration from under his feet began to strengthen, and Tang Li's inner sense of uneasiness began to become more and more intense, "Even if you know this, you can freely modify the gravitational constant, for us now, it is almost invincible." ”

"So, our focus now shouldn't be on what he can do, but on what he can't do!" his gaze drifted around with the splash of apple juice, chasing the fleeting fireworks, and finally returned to Tang Li's body, a smile appeared on the corner of his mouth, "The next thing to talk about is the content of the charge." ”

"What's charged?" Tang Li's face was confused, as if he didn't understand what Xiyue was saying.

"There is an increase and a decrease, there is a return for paying, there is no free thing in the world, excellent ideas are very expensive. Xiyue said as a matter of course.

Tang Li ran quickly in the playground, recalling in his mind what Xiyue had said to him.

"If I could modify the gravitational constant, I could easily subdue you by simply modifying the gravitational force between you and the Earth and changing the centripetal force that the Earth provides to you, but he didn't do that. ”

Tang Li took out an arrow from behind his back, put it on the bow, and aimed at the man in the sky, holding it but not firing it.

"Whether it's to make the arrow stagnate, or to make the arrow go backwards, to want to attract you to you, or to float in mid-air, the essence of these phenomena is that he modifies the gravitational constant between other objects and him, if these are not accidental, can I understand that his gravitational force can only act on him and another object, and there is a limit to the gravitational constant that he can modify. ”

The man floating in mid-air watched Tang Li's actions on the ground with cold eyes, this was not the first time he looked down on the ground from a high place, he had even stood higher than now, there, the crowd on the ground was like ants, and only some black spots could be faintly seen, but no matter how high the building was looking down on the ground before, it could not be compared with the current feeling.

Relying on scientific power to break free from the shackles of gravity and soar freely in the blue sky, for him, this feeling is almost like a god!

However, this god is not as omnipotent as everyone thinks, at least in Xiyue's eyes, he is just a shell that has broken free of gravity, and his soul and mind are still bound by the gravitational pull of the earth.

"He has not fully mastered his ability, the change of the constant will cause a series of physical phenomenon changes, involving the whole body, if you can't finely adjust the constant change, it will also pose a great threat to your own life, if you want to perfectly manipulate the gravitational constant, you need extremely powerful computing power to make up for it, he doesn't dare to enter the teaching building should be this reason, his ability can probably only be well played on the open terrain, judging from the vibration of the previous teaching building, he is still very cautious when modifying the gravitational constant, he must be a very careful person, I think, he's probably coveted your supercomputer-like calculus abilities for a long time. ”

The arrow in Tang Li's hand kept it in its hands, just aiming at himself, which made the man floating in the air feel a little surprised, but it was just some accidents. His fingers flicked lightly in the air, as if a precursor to the activation of his power, and the arrows that had been knocked to the ground before began to shake faintly, flying into the air with the movement of his fingers.

"Although he will have some movements in his hands before manipulating gravity, according to my judgment, even if he stands still, he should have a way to modify the gravitational constant, those actions before using the ability may just be his subconscious actions, or fake actions to cover up the truth, the only condition for him to modify the gravitational constant should be the place where he can see, so he will choose to float in the air as soon as I appear and obtain the commanding heights of the field of vision. As long as you keep pointing the arrow at him when you go out, he won't be able to use his previous trick to suck you straight through, and he will probably find a way to use the arrows scattered on the playground to attack you, but for you who have calculus ability, it shouldn't be difficult to calculate the trajectory of the arrow falling under the effect of gravity. ”

Plural arrows fell from the sky, mercilessly piercing the barrier of air, shooting towards the original owner, and the "∫" in Tang Li's eyes flashed one after another, like a beautiful flower butterfly, shuttling freely in the rain of arrows.

"Can you understand the difference between gravity and gravity? The reason why human beings can survive on the earth, which is constantly rotating on the earth, is because the center of the earth provides a centripetal force to human beings, which is the gravitational force between the earth and human beings, and now he has taken the initiative to give up the earth's protection of human beings, and he thinks that he has broken free from gravity, he is arrogantly floating in the air alone, thinking that he has mastered everything, and what you want him to understand is that he ...... It's just a mortal with wisdom. ”

Tang Li, who had dodged the rain of arrows, finally came directly below the man and began to accelerate in the next second!
