"Why don't I run back." This crazy idea suddenly popped into Lin Yun's mind.

The idea is crazy, but theoretically possible.

From Liangzhou to Dian City, the distance is nearly 2,000 kilometers, and ordinary planes need to fly for two or three hours.

His fastest speed reached the speed of sound, a little faster than a normal airplane, and even if the highway was a little bent, the distance was increased by another third. His speed is not slower than that of an airplane, so it is still possible for him to run back to his hometown in three hours.

Anyway, he still has to give it a try, if he can do it, if there is something important in the future, he doesn't have to wait for the car, just run.

He was really worried about his family, if there were snipers in the killers, it would be troublesome, and Dad, they didn't have the ability to dodge bullets.

This incident also told him that if the evil is eradicated, the enemy should be killed, but who is the one who can't get along with him?

After setting a goal, Lin Yun was ready to set off. Let Lingyi first send him a map in his mind, and then start locating, with Lingyi pointing the way, the route can be directly transmitted to his mind, and he won't get lost.

He stepped onto the highway and began to accelerate slowly, and after continuous acceleration, his speed finally broke through the sound barrier.

His top speed can reach the speed of sound, but this is the result of constant acceleration, and he can't run that fast under normal circumstances.

When the speed of the object is close to the speed of sound, there will be a strong resistance, causing the object to produce strong oscillations and the speed decays.

This phenomenon is colloquially known as the sound barrier. When the sound barrier is broken, due to the compression of the air by the object itself, it cannot propagate rapidly, and gradually accumulates on the windward side of the object to form a shock wave surface, and the acoustic energy is highly concentrated on the shock wave surface.

When this energy reaches people's ears, it causes a short and extremely strong explosion called a sonic boom.

At such a speed, at close range, the human eye can see innumerable clearly.

On this night, many drivers saw a mysterious light and shadow, but no one could see what it was, and many drivers heard a sonic boom, but it disappeared in the blink of an eye.

Many attribute this to a mysterious event, with the staccato footprints left on the more than 2,000-kilometre-long highway being the only evidence of the event.

If he wants to maintain the speed of sound, Lin Yun must accelerate every once in a while, and when he accelerates, he must kick the ground frantically, with the help of the interaction force generated with the earth, to produce an acceleration effect, only in this way can he maintain the speed of sound.

This also caused a large footprint to appear every distance where Lin Yun ran.

In fact, it wasn't that Lin Yun's feet were that big, but his strength was too violent, like a wild bull, causing the road surface to collapse.

It took Lin Yun more than four hours to return to Yun City, people will be tired, and after running a few hundred kilometers, he will have to recuperate, drink some spiritual liquid, and replenish his energy.

This kind of long-distance running is not without benefits, and when he runs, he can also practice basic footwork and basic body skills by the way, and he feels that he has improved a lot and his strength has improved a lot.

However, when he ran to Yunshi, he only had a small pants left, which was made of a little dragon skin when he was idle, although it was simple, but it was very durable.

The rest of his clothes had been torn to shreds when he had broken the sound barrier, and his shoes had worn out several pairs.

When he arrived in Yunshi, he went into a small space to change his clothes, and washed up by the way, he really couldn't see anyone now, he only wore a small pair of pants all over his body, his hair was all upside down, almost stuck to his scalp, his head could be broken, blood could flow, and his hairstyle couldn't be messed up, but his current hairstyle was so messy that he couldn't change it.

Because he was afraid that there would be another accident at home, he didn't bother with the hairstyle anymore, and hastily put on a set of clothes and changed the fork of Jiaolong's leather pants.

Although this thing sounds noble and noble, it is really not very comfortable to wear, it will rub the second brother, make people's blood swell, the dragon nature is lewd, and almost all dragon creatures have aphrodisiac effects.

Then he went home barefoot, yes, barefoot, because his shoes were worn out.

People all have reverse scales, Lin Yun's reverse scales are his family, if he finds out who wants to hurt his family, he will definitely tear them to shreds, but who is it, I really can't figure it out.

For the rest of the journey, Lin Yun slowed down, if this suit broke again, he would really have to go home naked.

Pushing open the door of the house, there are quite a lot of people, first of all, Lin Yun's family, parents, grandparents, uncles and uncles, except for children, everyone is here. This kind of bloody scene is really not suitable for children to watch.

The people of the Xuanling team, Long Zhan, Liu Mengxue, Mu Wan'er, Liu Xinyu, and Luo Haoyu all came, only Zhou Qingfeng and Zhao Dazhuang did not come.

Seeing Lin Yun walk in, everyone was stunned, didn't he say that in Liangzhou, why did he come back so quickly, and he became like this, his hair was messy, and he was barefoot.

"Dude, how did you become like this?" Long Zhan asked.

Lin Yun rolled his eyes and said, "You will know if you run back from Liangzhou in three hours!" "Anyway, Long Zhan already knows that his speed can break through the speed of sound, so it's okay to say it.

After speaking, Lin Yun went to the bedroom to put on a pair of shoes before coming out to meet everyone.

"Brother, have you found out who it is?" Lin Yun asked.

"We know who it is, but it's useless to know, these people are all from the Seven Killing Palace, and their tone is very strict, so they can't ask anything at all.

Of the three people we found, two of them had already committed suicide, and the remaining one would have almost died if we hadn't reacted quickly! ”

"Brother, what kind of force is the Seven Killing Palace, even the National Security Bureau can't find out." Lin Yun, the ability of the National Security Bureau, knows that in Huaxia, there is almost nothing they don't know.

Lin Yun estimated that there were so many killers who came to kill him yesterday, and it was all because of the indulgence of the National Security Bureau, in order to try his ability again. Although it was night, it was already early in the morning, and it was the next day.

"The Seven Killing Palace's forces are very ancient, it should have a history of hundreds of years, it is the largest killer organization in Huaxia in name, but it does not take on tasks through the dark web like abroad, but through various dark lines, so the specific location of the station has never been exposed, only known to be in the depths of the mountains of Yunnan Province.

The killers trained by the Seven Killing Hall are also very strict, and they will commit suicide when something is wrong. These three did not commit suicide, they should have to wait for rescue, after we intervened, they knew that they could not escape, and before the trial began, two of them committed suicide.

The rest of the one, I'm going to bring back to the headquarters, and let the master of hypnosis try it and see if I can find the nest. Long Zhan explained.

"It seems that there are still many things in this world that I don't understand, and there is such a killer organization hidden in Huaxia."

"This killer doesn't have to bother, I have a way to get him to speak."

If it was before, he really couldn't help it, but unfortunately, he just obtained a book of soul exercises last night-Divine Soul Decision, which records many methods of using spiritual power, and it is very simple to let an ordinary person tell the truth.

"Since my brother has a way, let's come."

"Brother, what does the country think about the Seven Killings Palace?"

"For such a terrorist force, of course, the country can destroy it, and if it can't be destroyed, it must be in its hands."

"That's good, we'll go and destroy it in two days." Lin Yun said viciously, he had just killed hundreds of people last night, which had a big impact on his heart.

"Eh, you'd better not leave the house these days, the Seven Killings Hall will not give up until three assassinations in a row, I'm afraid that my uncle and aunt will be in danger!" Long Zhan said with concern.

Now Lin Yun also knows who is going to assassinate his parents, it is Li Yu, he has only provoked such a person, Li Yu may be the killer invited through the secret line, the whole process has not gone through the Internet, otherwise Ling Yi would not have been able to find out.

He wanted to tear Li Yu to pieces, but Ling Yi told him that Li Yu was dead, and he died under the sneak attack of a small killer, so he couldn't take revenge if he wanted to.

This incident told him that evil must be eliminated and enemies must be killed, otherwise troubles will happen one after another.
