It was not until the thunder disappeared that the sound of the terrible and deep sonic boom roared, and the empty space of the earthquake hummed.

For a while.

Duan Yuren, who is frozen in the air, suddenly loses his momentum, and then falls to the ground. His breath is like an oil lamp that is about to go out.

His right arm, a piece of space-time turbulence, with the right chest, blood and flesh blurred, and even the color of thunder and lightning appeared.

Hu ---

Duan Yuren looks up with great difficulty and looks at Su Bai, who is walking slowly. His face is pale and his pupils are still filled with disbelief and panic.

"The sound barrier - you can - you can break the sound barrier

As an old master of Huajing in China, he naturally knows what breaking through the sound barrier means!

In the history of China, there are only a few people who can physically break the sound barrier by using the divine realm and the incarnation realm --- no, they can count it with one hand.

All of these people are the peerless pride of Fawu, among which Lin cangming is the most famous sword immortal in the past 100 years!

That's right.

Cangming sword immortal, who has a great reputation in the martial arts and martial arts circles of China, is not a pure Dharma practitioner, but a path of Dharma and martial arts.

It is said that he breaks the Dharma with his strength, defends the sword with his body, and understands the power of heaven and earth. At the peak of the realm, he "combines man with sword". His body breaks the sound barrier, and he can fight with an expert who has just entered the divine realm. He is a peerless figure. However, there are not many people who only know such secrets.

Nowadays, even the one who is the most close to the divine realm, who is recognized by the Chinese people, has not broken the sound barrier because it is too heavy a burden on the human body!

You know, the speed of sound is 340 meters per second! Nowadays, the technology of the earth is so advanced, but only a few real supersonic fighters are available. Many of the videos disclosed in the online military forum, the so-called broken sound barrier, are fake, just the shock wave generated at the critical point of the speed.

Except for the F22 and F35 of the United States and the j-20 of China, some of the other fighters can only fly at supersonic speed for a short time!

If supersonic speed is maintained for a long time, it will be a great test not only for Fighter materials but also for engines. These so-called supersonic fighters are made of special aerospace materials.

Moreover, this is the result of the development of Earth Science and technology for so many years.

But now, in front of Duan Yuren, someone directly breaks through the sound barrier with flesh and blood!

At this moment, Duan Yuren suddenly felt old.

As soon as he thought about it, he gave a miserable smile and looked at Su Bai, with a bitter face and a gasp: "I lost!"

"I'm willing to accept defeat. I won't ask about the map of cangming immortal's cave, and I won't reveal it! I also ask Su Xiaoyou to see that I saved Miss Su's face and let the Duan family go! As for me, whatever you do! "

At this time, the blue thunder light on the Su white skin has disappeared, but *'s upper body is still as crystal clear as jade, emitting a dazzling breath, like an immortal.

His face light swept a section of rain person an eye, suddenly smile a way: "you pour is to know interest."

Duan Yuren seems to be seriously injured, but he still has the power to work hard.

In his state, as long as he doesn't die immediately and has vitality in his body, he can absorb the aura of heaven and earth to recover and heal.

What's more, Duan Yuren has stepped into the peak of Huajing. He has thoroughly mastered the meaning of weak water sword, and has a preliminary understanding of the artistic conception of potential. His mental strength and the harmony between heaven and earth have been greatly improved, and his recovery speed is several times faster than that of the ordinary master of Huajing. In addition, his mental strength and sword skill may not have the power of World War I if he burns the spirit!

However, no matter how hard he tried, he was by no means the opponent of today's su Bai, and they were not a heavyweight at all.

Such a peerless evil can only be compared with cangming Sword Fairy and other brilliant people in history!

In this way, it's not unfair to lose.

Duan Yu Ren shook his head and said with a tragic smile: "Su Xiaoyou is a man of extraordinary talent. He is the most arrogant person in thousands of years. I believe that even if I try my best, I can't be Xiaoyou's opponent, so I'd better not waste my time!"

Su Bai took a deep look at him and suddenly said, "you go!"

Duan Yuren's face was filled with amazement.

"Won't you kill me?"

"When did I say I wanted to kill you? If I want to kill you, do you really think I can escape? " Su Bai shook his head and said faintly: "in any case, you saved my sister before, so this matter has been exposed, you go!"

Duan Yuren looked at Su Bai and was silent for a long time. With only one hand left, Duan Yuren got up and bowed to Su Bai and said, "thank you for your kindness

Without paying any attention to Duan Yuren, Su Bai went to Su Qingyao and looked at her ruddy face. She relaxed in her heart and said, "elder sister, are you in a stable condition?"Su Qingyao nodded, suddenly frowned and looked at Duan Yuren's back in the distance, "Xiaobai, you just let him go?"

"Or else?"

"If you hurt him like this, will the Duan family give up?"

With a faint smile, Su Bai said, "he is a smart man and knows how to do it --"

"besides, I have a purpose to let him go --"

"what?"

Su Bai's eyes narrowed slightly. Instead of speaking directly, she said: "when I was fighting with Duan Yuren, I also felt a very secret breath - but he seemed to be scared by me. Now he is completely hidden and dare not come out again!"

"What's more, the breath is very strange. According to my guess, it should be a monk who belongs to the blood witch family!"

"These guys are very eager for the essence and blood of the strong. I don't believe he can stand the temptation of a single person who is at the peak of his life."

Su Qingyao's eyes stare round and looks at Su Bai. She doesn't speak for a long time.

When did my little brother become so black?

Unexpectedly, Duan Yuren was used as a bait. Fortunately, he was very grateful to Su Bai. I don't know how he would feel if he knew the result.

At the same time.

In the forest.

Duan Yuren's face is indifferent, but his heart is extremely alert.

Although he didn't know why he let himself go, he has now entered the peak of the world, his spirit and mind are more in line with heaven and earth, and he is more sensitive to the sense of crisis.

He can feel that somewhere in the dense forest, there seems to be a breath of nothing, staring at himself!

I'm afraid, that Su Bai has long been aware of this scene, will be so generous to let himself go!

Duan Yuren hummed coldly in his heart, and a trace of madness appeared in his eyes. Although he didn't understand who was staring at him, he was ready to work hard!

Rustling -

the wind blows the dead leaves on the ground, and the slow walking rain suddenly stops.

A whole body shrouded in the black robe within the shadow of the moment emerged.

"It's you?! ---"

at this moment, Duan Yuren's voice was full of shock and fear.
