Ling Feng was from the earth, and he had a different view of speed from that of a Heavenly Martial Artist, and in his opinion, speed was inseparable from time and space.

There is a formula in physics about speed, the distance is equal to the time multiplied by the speed, and the reverse is the speed is equal to the distance divided by the time.

In other words, the factors that affect speed are distance and time.

In other words, the longer the distance, the shorter the time, and the faster the speed, where the distance is the spatial distance.

In other words, the speed should not only be affected by time, but also by the constraints of space, so Ling Feng felt that his perception of space could be completely added to the inch.

Speaking of which, for other people, this matter was even more difficult to do than ascending to the sky, but for Ling Feng, it was not particularly difficult.

Because of the relationship between time, space, and speed, no one understood it more thoroughly than Ling Feng.

In addition, their comprehension of space and time was far lower than Ling Feng's, especially Ling Feng's achievements in time, even farther than the Great Emperor.

With a theoretical foundation and a perception of time and space, the only thing lacking is to organically integrate them together.

Soon, a vague thought appeared in Ling Feng's mind......

In this way, as the days passed, the idea in Ling Feng's mind became clearer and clearer.

After a few more days, Ling Feng's eyes opened suddenly, and a light burst out from them, and then he slowly stood up, and with one step, the whole person appeared a hundred meters away.

Then, the inch flash was launched, almost in the blink of an eye, and his whole person ran tens of thousands of miles away, which was more than ten times faster than before.

Seeing this result, a smile appeared on Ling Feng's face.

And it just so happened that Xiao Hei and the others came over at this time, and Ling Feng cleaned up his mood and withdrew from the Emperor Pearl.

As soon as he came out, Ling Feng saw two people, one was Ao Qin, and the other was Xiao Zhengtai, who looked only thirteen or fourteen years old, who looked a little similar to Ao Qin.

"Are you Xiao Hei?" Ling Feng immediately thought of this Xiao Zhengtai and Xiao Hei together.

"Ling Feng, what kind of eyes are you, what, my appearance surprises you?" Xiao Hei glanced at Ling Feng and said angrily.

"No, no, it's just that why are you so small?" Ling Feng really didn't expect it.

"That's right, the lifespan of our black thread Jiao clan is longer than that of you humans, for us, two or three hundred years old is considered an adult, and now it is still in a juvenile state, if it is not cultivated stronger, otherwise, after the transformation, it will be even smaller. Ao Qin explained.

"I see!" Ling Feng realized at this time.

"Alright, let's go. Xiao Hei couldn't stay still for a second at the moment, so he wanted to get out quickly.

If it weren't for his mother's insistence on giving him a shapeshift, he would have left long ago, and he would have had to wait three days.

"Auntie, if there's nothing going on, then we'll go?" Ling Feng glanced at Ao Qin, after all, he didn't know when he would come back after this trip, he had to ask.

"Go ahead, remember to come back and have a look when you have time!" Ao Qin didn't care much on the surface, but Ling Feng could see that she was very reluctant in her heart.

"Let's go, let's go......"

Ling Feng wanted to say something, but Xiao Hei didn't care about it at all, and pulled Ling Feng out, Ling Feng could only smile helplessly a few times, and followed Xiao Hei out of here.

After walking for a short time, they came to the side of a spatial door.

"Xiao Hei, what are we doing here?" Ling Feng didn't know why.

"You don't know this, the place we are in now is not Tianwu, but a space opened up by the Dragon Emperor, and only through the door of this space can you get out. Xiao Hei explained.

"Then where will you go after you go out?" Ling Feng suddenly realized that his previous Dragon Tomb existed in a certain Jedi, but now it seemed that he still thought about it simply.

"It could be on any continent, because there is a passage to the door of this space. After Xiao Hei finished speaking, he asked again: "Say, which continent to go to, I'll set the coordinates." ”

"Xizhou!" Ling Feng was still thinking about Ouyang Qiushan's Tribulation, it was a Holy Tribulation, and after observing it, it would be of great benefit to his future cultivation.

Moreover, if you calculate the time, there is still one day before Ouyang Qiushan Crossing Tribulation, and you can just go back.

"Okay, I'll go and set the coordinates!" With that, Xiao Hei ran to the side of the space door and fiddled with it for a while, and after a few minutes, he retreated back and said, "Okay, let's go in with my door." ”

"Let's go!" said the two of them into the spatial portal.

But they didn't know that the moment they left, Ao Qin's figure appeared where they had just stood, and it took a long time before leaving.

Thousands of feet above a dense forest in Xizhou, a spatial rift suddenly appeared, and then two figures fell out of it, it was Ling Feng and Xiao Hei.

As soon as he came out, Ling Feng found that he appeared at a thousand zhang high in the sky, he was startled, and out of instinct he released the Vermilion Bird, so as to avoid encountering difficulties, and then turned his head to look at Xiao Hei, and said angrily: "Why didn't you tell me that the exit was at a thousand zhang high in the sky!"

"Didn't I tell you? No way, I'm sure I told you, you don't remember. Xiao Hei sloppily looked at it, he was too excited to forget about it, and he was a little reluctant but embarrassed to admit it.

"You kid!" Ling Feng could see this kid's thoughts at a glance, but he didn't pursue it too much.

"Ling Feng, what about the lightning, why isn't it with you?" Xiao Hei saw that Ling Feng seemed to see something, and immediately changed the topic, and at the same time, he really wanted to lightning.

"He was bored, so he ran out to play, and I don't know where it is now. Ling Feng also thought about it a little, after all, they had known each other for the longest time, and they had also experienced life and death together.

"Shall we go find it?" said the little black.

"I have something to do and go back to the sect first, and when it's done, we'll go again. Ling Feng also had this intention, but at the moment, Ouyang Qiushan Tribulation was the most important.

"Okay, I'd love to see the human sect too, but it's so boring to pass like this, or let's compete with the speed and see who can run faster. Xiao Hei suddenly became interested and said.

"You want to compete with me?" Ling Feng was stunned for a moment, thinking that he had misheard.

"Yes, why don't you dare to compare with me?" Xiao Hei thought that Ling Feng was scared, and suddenly became proud.

"I dare to compare, but I'm afraid that someone will cry if they lose. Ling Feng smiled and said.

"Che, do you think you've won? Let me tell you, our Blackline Jiao clan is a wind-attribute demon beast, and speed is our specialty. Of course, Xiao Hei wouldn't think that he was inferior to Ling Feng, otherwise, how could he take the initiative to compare speed.

"Okay, then let's take a look?" Ling Feng asked.

"Come, one, two, three, start!" As soon as Xiao Hei's voice fell, the whole person turned into a black shadow and rushed out, while Ling Feng sat on the back of the Vermilion Bird on the ground, unhurriedly retracted the Suzaku, and then chased after him like a walk in the field.

But he looks very leisurely, but every step of his body appears out of thin air hundreds of meters away, which is very strange.

Almost in the blink of an eye, he threw Xiao Hei far away.

"Stop, stop, don't compare. When Xiao Hei saw this, he didn't understand that he had already lost, but he couldn't understand how Ling Feng could have such a fast speed.

Moreover, it was obvious that the people had not used all their strength, otherwise, ten of them would not be Ling Feng's opponent.

"What, admit defeat?" Ling Feng smiled, if it was anything else, he might still have the possibility of losing, but compared to speed, he was really not afraid of anyone.

"How did you do that?" Xiao Hei couldn't figure out how his dignified emperor in the wind could lose so completely.

"Want to learn?" Ling Feng asked with a smile.

"If you dare to teach, I will dare to learn!" Xiao Hei said confidently.

"It's not impossible for me to teach you, but you have to listen to me in the future, I let you go east, you can't go west, how about it?" Ling Feng asked with a smile.

"You are a bully clause, I won't agree!" Xiao Hei immediately shook his head and said, what he pursues is freedom, how can he let these things bind him, and his brother can't do it.

"I really don't agree? I can tell you, this method is my own creation, only I can do it, if you don't learn it this time, the next time I want to learn, I don't necessarily teach it. Ling Feng said with a smile.

"You, you change the conditions, as long as you don't restrict my freedom, I will agree to anything. "Xiao Hei really wants to learn, because speed is its strength, and now there is a way to greatly improve its strength, how can he not want to learn.

It's just this condition that makes it difficult to accept.

"But what should I do if I have this condition?" Ling Feng asked with a smile.

"Then I'll ......" Xiao Hei wanted to say that he couldn't learn, but when the words came to his mouth, he swallowed back, but letting it accept such a request was like killing him.

"What about you?" Ling Feng asked with a smile.

"Yes, I promise you, but you are not allowed to restrict my freedom. In the end, Xiao Hei couldn't resist the temptation of this method and compromised.

"When did I say that I wanted to restrict your freedom, I just asked you to listen to me, you thought too much about it, and this is also my fault!" Ling Feng said angrily.

"Didn't you say it earlier!" Xiao Hei was a little depressed, if Ling Feng had said this, would he still need to be so entangled.

"I wanted to say it earlier, but I saw that you were in a hurry and it was funny, so I teased you, but I didn't expect you to really agree. Ling Feng laughed.

"I don't have the same knowledge as you!" Xiao Hei ignored Ling Feng's ridicule and said a little impatiently, "Well, when will we start learning?"

"This is not something that can be learned overnight, it is better to go back to the Heavenly Gate Sect first, and when everything calms down, I will teach you. Ling Feng said.

"Well, when the time comes, you can't afford to pay the bills. Xiao Hei nodded, he knew that Ling Feng was really in trouble, and he didn't entangle.
