After Catherine finished speaking, the purple-haired girl suddenly pursed her mouth and said inappropriately: "Shen Ning'er's apple is comparable to the apple that smashed on Newton's head." ”

Newton? Li Yuanhao heard that this was a person's name, the surname was Niu, the surname of Niu was not, and Niu Fugui at the foot of Yuelu Mountain was surnamed Niu, but the word "ton" in a single name was very strange, and did it mean one meal or two meals? However, "change your so-called gravity...... Acceleration, is there any practical significance?"

"Yes, and it's significant, gravitational acceleration is generated by gravity, and if gravity is small, a person can jump very high. Yes, the so-called flying of human cultivators, or more precisely, can only be regarded as jumping, but after jumping, you stay in the air for a longer time, and eventually you will still fall to the ground, which also explains why after you ascend from the human world to the heavens, when you first enter our world, you will feel a coercion, in fact, it is not coercion, but a greater gravitational force. ”

Li Yuanhao gradually understood that gravitational acceleration represents a fixed parameter that is not affected by the nature of the object itself, the smaller this parameter, the higher the person jumps, and this parameter does exist, around the body, everywhere, but it can't be touched, but she still has a question: "Shen Ning'er, as a traverser, why didn't she find that the gravitational acceleration was modified in the first time?"

Because she is a soul crossing, not a body crossing, Shen Ning'er's original body functions have adapted to the gravitational acceleration of the world, and it is normal not to find it, people usually do not doubt obvious things, and Shen Ning'er has no knowledge of physics, and under the inertia of thinking, she would not think that the basic physical parameters of the world have been modified. It was a negligence in our work to guide the female Qincha into the world, and we did not evaluate the guide samples, so when we chose Shen Ning'er to enter the world, we conducted a lot of systematic evaluations, and finally decided to let her enter the experimental time and space and become our research object. ”

Li Yuanhao smiled bitterly, it turned out that there were so many stories behind Shen Ning'er's appearance, if Shen Ning'er knew the truth of the matter, she would not be so angry that she would jump to her feet and scold.

"Although there are some things that I don't understand yet, I probably understand what you said. You mentioned that you modified two physical parameters, what is the second one?" asked Li Yuanhao.

"We modified the proportion of oxygen in the air. Catherine said, reaching out a little more in the air, and a round cake of light spots was projected in the air, and the pie chart in the air was divided into several parts, each occupying different proportions: " First of all, I will explain to you the composition of the air, the ubiquitous air around us is not a single component, in simple terms, it can be divided into three parts, the first part is oxygen, the second part is nitrogen, the third part we will make it a few gases, of which helium is the most, about seventy-eight parts of a hundred parts are nitrogen, a few breaths are very few, only one of the hundred, oxygen accounts for the remaining twenty-one points, and among the three gases, oxygen is the most important, oxygen is inhaled into the body through breathing, and will be combined with hemoglobin to provide energy for metabolism。 ”

Catherine lit the round cake in the air and gradually expanded the proportion of oxygen: "We have increased the oxygen content to 50 points today, compared to nitrogen, oxygen is heavier, so it is more suitable for the gravitational acceleration of the world, there will be no atmospheric escape, providing a stable environment for the world, but not the higher the oxygen concentration, the better, the high density of oxygen content will cause oxygen poisoning." Man is a very adaptable animal, and people in the human world quickly adapt to the concentration of oxygen in fifty shares, and you call the degree of oxygen and hemoglobin binding as absorbing breath, and the stronger the breath, the higher the degree of binding. But the heavenly people go down to the mortal world but there are many obstacles, one is not adapted to the acceleration of gravity, and the other is not adapted to the proportion of oxygen, so every time we send someone to appear in the world, we will always formulate relevant protective measures, the mask you are talking about, the scientific name is gas mask, the so-called armor on the body is a protective isolation suit, and what is worn in these is a combat suit. ”

Li Yuanhao nodded, thinking back to the few times he had seen heavenly people descend to the mortal world, one was above the Xiongnu grassland, and the other was in the twenty-four immortals in Tai'an City descended to the mortal world, and they were indeed wearing strange armor: "What are those rays of light that fall from the sky?"

"It's called gravity flow. This time it was the purple-haired girl who replied, "It's my invention, hehe." On the grassland, the person who fell from the sky was me, Hao Lian Liushui was so annoying, I wanted to beat her for a long time, but unfortunately I didn't kill her!"

Catherine glared at the purple-haired girl fiercely, the girl's neck shrunk, and she retreated, Catherine turned to look at Li Yuanhao: "In order to save you, she self-forged and signed the relevant documents, which is something that we absolutely cannot tolerate, so she has been punished and has been demoted from the first level to the ninth level." ”

Li Yuanhao didn't know how they were graded, but she knew that there was a huge gap between the nine-grade system in the temple on earth, and there was a huge difference between the first product and the ninth grade, one in the sky and the other underground, Li Yuanhao nodded at the purple-haired girl, showing an apologetic expression.

The purple-haired girl reached out and patted her little breast, meaning that they are all small things, don't take it to heart, you, as my idol, are worthy of me.

On earth, the sun in the sky goes out and falls to the side of the earth, and the aurora flashes in the sky, forming chaos all over the sky, and the world is in chaos.

In the palace of Luoyang, Xichu, Zhuge Weiwei has been sitting by the lake, staring at the mysterious small mirror, until Li Yuanhao disappeared in front of that door, Zhuge Weiwei did not put away the small mirror, but stretched out his hand on the small mirror, he saw what happened in Tai'an City through the acacia tree, and also saw the imminent movement in the Nanliang Palace, the fragmentation on the snowy mountain, and finally the small mirror gradually dimmed, as if he had come to the end of his life, and was lifeless.

Zhuge stood up, picked up the small mirror, put it in the palm of his hand, the back of the small mirror was slightly hot, and then threw it into the lake without pity, poof, and the small mirror sank towards the bottom of the lake.

Fan Xiao on the side hurriedly ran to the lake, his heart full of pity: "Sir, why did you lose such a magical mirror." ”

Zhuge Wei I turned around and left, his clothes fluttering, he didn't look back, and his voice had already come: "Now that the human coefficient is on Li Yuanhao, it has little to do with me, and the reason why I lost the treasure in your eyes is that an iPad without power is useless." ”

"Epade?" Fan Xiaokuai frowned, looking into the lake, where there was an apple that had been gnawed on the back of the small mirror.
