In the image projected by the acacia tree, Shen Ning'er tore open the letter, and the transmission affects the change of angle, the first sentence: The earth is round, this assumption is not true, because when my three souls and seven spirits traveled thousands of miles, they did not return to the original point, but flew towards the sky, but returned to the original point. Sentence 2: The sun in the sky is a big fireball, that's right, but it's nowhere near as big as the earth.

Catherine nodded, and praised Li Yuanhao a little: "The two letters you wrote are very concise and objective, without superfluous subjective feelings, Shen Ning'er is a master of business, has a keen sense of smell, is good at pondering people's minds, and has enough knowledge of economics, but she doesn't have the logical thinking of science, she can find some answers from your letters, but she will be one step away from the truth." ”

Shen Ning'er in the video folded the letter, frowned and thought hard, suddenly she seemed to remember something important, picked up an apple beside her, threw it into the air, and then watched the apple fall to the ground, Shen Ning'er slowly closed her eyes, let out a long sigh, and then opened her eyes, full of exhaustion and pain: "I see, it turns out that this world is so simple and so complicated, ridiculous, pitiful!"

Li Yuanhao was still unconscious, she didn't understand how Shen Ning'er knew the secrets of heaven and earth, but from Catherine's gaze beside her, she knew that Shen Ning'er knew the truth.

Catherine stretched out her hand and tapped the acacia tree, and Shen Ning'er's image disappeared: "I miscalculated Shen Ning'er, and she is far smarter than I thought." Before I explain it to you, I need to explain to you Shen Ning'er, Shen Ning'er and her teacher, the female Qincha, are all traversers, that is, people who are born to know, unlike Shen Ning'er who has a solid foundation in economics, the female Qincha was a cook before the crossing, and she has a big secret that the world does not know. Without Li Yuanhao asking, Catherine paused for a moment and told the secret of the female Qincha: "Actually, before this female Qincha crossed, it was a man's ......"

Li Yuanhao opened his mouth, closed it again, and chose to be silent, men wear women, thick familiar routines, amazing, Shen Ning'er's master, that Mr. Gonglang of the Ministry of Works, forcibly broke a male cook into a female Qincha, if the Ministry of Labor waiter does not know that the female Qincha has a man's heart, then it is indeed pitiful, if he knows the male heart of the female Qincha, then, that ...... Then, I, Li Yuanhao, can only give you a thumbs up, and send sincere greetings and blessings, wishing you a hundred years of good harmony, eternal marriage, and early birth...... Takako!!

"Ahem. Catherine coughed twice and brought the shocking secret of the female Qincha: " For us, the female Qincha has enough knowledge reserves, she knows the form that a normal world should have, and the Ministry of Engineering has the thinking of an engineering man, if the two join forces to explore, it is very likely to know the secrets of the world, so we create an illusion and let the two go to sea in order to seek the truth of the world, but in fact, they are going astray, because the direction of exploring the truth is never east, west, north and south, but upward, and then we consciously guide Shen Ning'er's soul into the experimental time and space. For the appearance of the female Qincha, we call it a pulse interference to the system, and the appearance of Shen Ning'er is a continuous step interference. ”

Li Yuanhao automatically filtered out Catherine's professional terms, only listened to those he could understand, and firmly grasped the other party's train of thought.

Catherine also deliberately slowed down the speed of her speech, giving Li Yuanhao time to think, and when Li Yuanhao thought and digested completely, she continued: "Shen Ning'er once expounded an argument to you, this world is a bit weird, people should have the same basic rights between people, one person can be a little stronger than the other, a little taller, a little more powerful, this is acceptable, but this difference should be within a certain range, there should be no one against a hundred, With a situation of one enemy against a thousand, if it appears, it can only mean that the world is wrong, and it is ridiculously wrong. ”

Li Yuanhao heard this sentence, Shen Ning'er broke into the palace at night to save Shen Wanqian, and was finally captured in the palace, the two had a conversation, and then Li Yuanhao returned to Tai'an City from the Hun grassland, the two had a conversation, this time Shen Ning'er put forward a new point of view, the strange root of this world is that someone has changed something, these things are obvious, just around, but not easy to detect.

"Shen Ning'er is right, we have indeed changed two important things in the world. Catherine pointed to the two spells on the wall, "We actually changed two physical parameters of the human world. ”

"Physical parameters?" Li Yuanhao felt that this word was very important, but he didn't understand the meaning of this word at all, could it be that those two unaesthetic spells were unreasonable parameters?

"First of all, it's not a charm, it's Arabic numerals, and the next few children and mothers represent units. Li Yuanhao didn't speak, but Catherine could read her thoughts, and proposed a few other new terms, Catherine smiled, I don't know if she was laughing at herself or laughing at Li Yuanhao: "Sure enough, without basic cognition, the difficulty of talking has greatly increased." ”

Sighing, regardless of whether Li Yuanhao could understand it or not, Catherine said: "The so-called physical parameters are fixed constants that exist objectively and do not transfer by human consciousness, so I will give you an experiment." Catherine stretched out her hands, and two marbles of different sizes lay in the palms of her hands: "These are two qualities, well, quality is a new term, not good." These are two marbles of different sizes and weights, according to the general inertia of thinking, two marbles fall from a high altitude at the same time, and the heavier one will land first, in fact...... Both marbles will land at the same time. ”

With a slight tilt of his wrist, two marbles fell from the palm of his hand, and they really fell to the ground at the same time under Li Yuanhao's gaze.

"It's a very simple experiment, why two marbles of different weights can land at the same time, because the process of accelerating the fall of two marbles is always at work not by weight, but by a fixed physical parameter, which we call gravitational acceleration. ”

"Gravitational acceleration?"

"Yes, gravitational acceleration is gravitational and does not change because of the weight of the marbles, we modified this parameter. Catherine pointed to the top one of the two spells: "This parameter is the gravitational acceleration of the world, about one-tenth of the normal world, Shen Ning'er threw an apple into the air, at the same height, an apple landed, the greater the gravitational acceleration, the faster it landed, on the contrary, the smaller the gravitational acceleration, the longer the landing time, Shen Ning'er judged that the gravitational acceleration parameter was changed through the time of the apple landing, and then speculated that there should be someone above the world looking down and monitoring the world, so she will be negative." ”
