The frame of reference is a very mysterious understanding for many powerful seniors such as Tiandao. Pu Hongyu knows that he is too far away from that realm, so he has not yet deeply felt it. "But re-exploring nothingness made Pu Hongyu confused. Once he observed it, Pu Hongyu's understanding changed every time. Pu Hongyu had a headache. He found that he couldn't find the pattern. Every change made him study it carefully for hundreds of years, and then he came out to meet Yue Ling'er and Zi Yejian, and then greeted his parents and elders. Yue Ling'er looked at Pu Hongyu who came out with a sad face again, and gently held his hand: "Hongyu, is there no progress again?" Pu Hongyu sighed and nodded: "It's been so many times, and there is almost no progress. I I found myself in a dead end and couldn't get out. " "Take a rest. It's hard to understand the secrets of being so tired all the time. Hongyu, let's go for a walk inside the boundary shell today. It's rare for this girl Ziye to stay in seclusion without waking up. Come, this time, this time just the two of us" Yue Ling'er's voice became lower and lower. Pu Hongyu hugged Yue Ling'er lovingly and lamented that he was a foreign affairs disciple, but he was able to be favored by her. Now it's been a long time since he had a world with two people. Pu Hongyu nodded, waved his hand casually, and then the two of them left the Qiankun Hunyuan Formation. In the boundary shell, there was gray everywhere. Pu Hongyu stretched out his holy thoughts to the edge of the boundary shell, and he could see the speed outside. The sea of ??evil. The madly filthy air has not diminished. There is also a more condensed trend, which treats this world shell as a delicacy. Fortunately, the world shell is extremely tough, and I don't know what kind of material it is made of, and it is not afraid of these filthy smells. Pu Hongyu found a place that was still open and clear, took Yue Ling'er there, and set up a formation, where the stream and the bamboo pavilion in the Qingyun Sect of Blue Star appeared again. Yue Ling'er ran up to her in surprise, and took off her shoes as Pu Hongyu had just seen her, revealing a pair of delicate feet, and gently placed them into the stream. "Hongyu, you are coming too." Ling'er's eyes were as charming as silk. Pu Hongyu was fascinated by the sight, secretly took a sip of water, and sat side by side with Ling'er. The cool water of the stream penetrates into the lungs, and Ling'er slowly nestles in Pu Hongyu's arms. "Hongyu, there should be no one here to take a peek" Ling'er asked softly. "No, of course not. If anyone dares to look, I will dig out his eyes and throw them into the stream to feed the fish." Hongyu said boldly. "Hongyu, I want to go swimmingare youwill you come?" Yue Ling'er's face was so red that she could drip honey. "Come. Of course I will come." As he spoke, Ling'er was already swimming like a fish in this creek that was not big but big enough for swimming. "Plop" sound. Compared with Ling'er's silent entry into the water, Pu Hongyu was simply in a hurry. Like a salmon chasing Yue Ling'er at high speed, Ling'er let out a sweet laugh and fled forward with a more graceful posture than the fish. Pu Hongyu laughed "haha", and suddenly he transformed into a sucker fish that was no more than an inch long. Without Yue Linger's knowledge, he secretly swam to Linger's side, and then used the sucker on his mouth to stabilize the fish. It is firmly attached to Ling'er. Swim forward with Ling'er. Yue Ling'er didn't even notice that such a small fish was attached to her body. He was still watching where Pu Hongyu had hidden himself, but after watching for a long time he didn¡¯t see the guy chasing after him. He suddenly became anxious: "Hongyu, Hongyu, where are you" "Don't panic, Ling'er, I'm right here with you. Around you." Yue Ling'er searched again but still couldn't find it: "Hongyu, where are you? Why can't I see you?" Pu Hongyu changed again and hugged Ling'er with both hands. He opened his mouth wide and stretched it out. Ling'er let out a "àÓßÌ" sound and was stunned for a moment. Then he hugged Pu Hongyu with his backhand, and the two of them sank into the stream. After a while, the stream vibrated unusually, as if there was a huge monster churning below. It was really unusual for the gods and kings to do things. Extraordinary. "Hongyu, I want, I want to give birth to a child for you okay?" Ling'er whispered. Those words triggered a new round of impact on Pu Hongyu. After a long time, he finally released the essence of life, but this time he did not turn the essence into energy. Under Pu Hongyu¡¯s careful guidance, the healthiest and best seed took up residence in Ling¡¯er¡¯s body. Ling'er hugged Pu Hongyu shyly and let the stream wash over their bodies. It took a long time for the two of them to come out of the water again. After tidying up her clothes, only God and Earth know everything. It was such a wonderful experience. Pu Hongyu returned to the Qiankun Hunyuan Formation with Ling'er in his arms. He happened to meet Zi Ye. She looked at the two of them strangely and showed such an expression. . ? ? ? ? ? ? ? ?The girl smiled and ran away. Zi Ye blushed and walked to Pu Hongyu: "Hongyu, just now, did you just me, I want it too" Zi Ye's words are more effective than any aphrodisiac. The dragon raises its head, and the dragon raises its head again. , Pu Hongyu took Ziye to another place After making a lot of noises, Pu Hongyu had never felt such passion in life, and the feeling of decadence was swept away. After another half month of rest, he again Retreat. There are no rules, no rules at all. Pu Hongyu remembered his realization last time that this void energy can exist in any space. Including him filling up the energy of the artifact-killing weapon in the Open Sky Sword again, but this time he retreated and found that the energy of nothingness could no longer be found in any space, as if everything had suddenly disappeared. The energy of nothingness in the artifact has turned into static energy again, and Pu Hongyu can no longer simulate it. Why is it called the energy of nothingness? How can energy have the characteristics of nothingness? Something is something, nothing is nothing. This is the law. If energy wants to become nothingness, it must be transformed into something else. It cannot be like this. Disappearing is simply impossible. If the scientific research of the Phoenix Galaxy says that energy and energy can be transformed into each other, but when the energy of nothingness disappears, the amount of annihilation does not change. What is it transformed into? Pu Hongyu thought about the transformation of energy, and there is another kind of particle without mass, that is, light. Only light exists without mass. Every time there is an exchange and transfer of energy, there must be light. But Pu Hongyu didn't notice any changes in the light. Suddenly Pu Hongyu slapped his head: "How could I forget that light is divided into visible light and invisible light. That's because their wavelengths are only within the range that the human eye can observe. A very small intersection range. The light within this intersection range can be seen by the naked eye. I have been watching the changes in light with my eyes. No wonder I can't find it." Pu Hongyu unfolded his holy thoughts, and the world in front of him immediately changed completely. , countless lights are twisting and changing, filling the entire space, and new problems emerge. Pu Hongyu could not conclude that those lights were related to nothingness. The number of photons was too huge. You must know that an ordinary lit candle can release 100 million photons in one second. If you want to count the number of photons in the light that fills the space, even with Pu Hongyu's current holy thoughts, it is impossible to complete it, because the light is still moving, and it cannot stop here for you to count before moving on. Pu Hongyu expands his own domain. With Pu Hongyu's current cultivation level, he is already familiar with space changes and time changes. Those are rules that even god kings can master. How can it be difficult for Pu Hongyu, whose cultivation level is far beyond that of ordinary god kings? Anything with mass only reaches the speed close to the speed of light. Their speed will have a corresponding relationship with time, which is a relationship that can be obtained through calculation formulas. But light does not hurt, and light has no quality. When Pu Hongyu accelerated time to five thousand times, the light still did not change at all, and time had almost no effect on it. Pu Hongyu tried to accelerate other objects to the speed of light and then accelerate time accordingly. Pu Hongyu discovered changes. In addition to changes in time and speed, there was also a subtle change in space. If Pu Hongyu didn't observe carefully, he would hardly be able to spot it. When time and speed adapt to each other, the "theory of relativity" from the Phoenix Galaxy no longer applies, and objects and time become normal. The speed of an object decreases according to the multiple of the acceleration of time. That is to say, if the speed of the object is one third of the speed of light, if time needs to be accelerated to 10,000 times, it will adapt. So now, due to the acceleration of time, the speed of this object can only be one-third of the speed of light and then decrease by 10,000 times. There is no change from running in normal space. But when it changes, it becomes stretched and thinned in space. This is very abstract. If Pu Hongyu insists on explaining this phenomenon, it is equivalent to a balloon that was originally injected with a large amount of air, and its volume was inflated by the air. And this is not just a space getting bigger, but the entire world, including everything in it, is getting bigger, objects are getting bigger, and energy is also getting bigger. Even photons become bigger, and after being huge, they become thin. It feels to Pu Hongyu that the world has become bigger. He seemed to have shrunk and could see everything clearly at a glance. It's so clear, it was just a small gap. What is now displayed in front of him has expanded into a big rift valley. The originally thick colors can now clearly see the basic composition of each color. This is different from microcosm. Microcosm and Xumina Mustard Seed are both magical powers, but the changes in front of Pu Hongyu are just the adaptation of time and speed. This is the law of the universe itself. It has nothing to do with whether you have supernatural powers or not. You are just a bystander and a discoverer. Although this is wonderful, it does not bring any progress for Pu Hongyu to realize the power of nothingness. Pu Hongyu, who was not interested, suddenly became a little playful, I will accelerate you to the maximum. See if you explode. Just like most children like to blow up their balloons, blowing them bigger and bigger, the bigger the better. If they accidentally exceed the limit, the "bang" sound will scare themselves. I'll speed you up, speed up, speed of light, time, all go up to me. Pu Hongyu exerted all his strength, and his whole body's cultivation was at full speed. Even in the Qiankun Hunyuan Formation, he could feel the unusual fluctuations in his room. The power was terrifying, but no one dared to disturb it. To continuously accelerate an object and change the time patterns around it, the whole process consumes a lot of attention and cultivation. After playing for several days, Pu Hongyu finally got tired, but the objects inside had been accelerated to a terrifying number by him, but there was no tendency to burst like a balloon. Pu Hongyu gave up and no longer maintained the acceleration of time. At the moment when time suddenly stopped accelerating and returned to normal, the object that Pu Hongyu had been accelerating suddenly flashed a bright light. Then it flew away, and Pu Hongyu felt the existence of void energy at the same time, but it quickly disappeared again. Pu Hongyu quickly cheered up and looked for the object accelerated by him, but he searched the entire space within the world shell and spent two hundred years without finding anything. lost? Could it be that it has escaped from the boundary shell? This is impossible. If it has flown out of the boundary shell, it should also have rushed into the Du Nie Sea. However, there is obviously no change in the Du Nie Sea. Where did it go? Pu Hongyu spent two hundred years in seclusion before coming out this time. He and Ling'er had promised to come out once every hundred years, but they broke the promise again. After Pu Hongyu came out, he went straight to his sister Feiyu anxiously. He told her this discovery. Unfortunately, Feiyu's cultivation could only accelerate time to more than 20,000 times, which was the limit.
