Xia Fan originally wanted to attract the last Flying Eagle Martial Arts Pavilion together and let the beasts be wiped out. But after waiting for more than an hour, no one came.

"It seems that the people from the Flying Eagle Martial Arts Pavilion were frightened and didn't dare to show up. He sighed lightly, still having some regrets in his heart, he was not finished yet!

"Hey, what's that?"

Xia Fan accidentally raised his head and glanced in a direction deep in the Valley of the Fallen Gods, but he was suddenly stunned.

I saw that far ahead, behind a dense forest, there was a colorful halo of Daodao.

The tree under his feet is more than 30 meters high, and he can penetrate the dense forest when he straightens up, so that he can discover the existence of colorful halos at such a distance.

"Let's go, let's see!"

He was too curious in his heart, and felt that this halo must be extraordinary, so he immediately rode an adult coiled foot dragon and pointed in the direction where the colorful halo appeared: "Go, go to the east." ”

The cross-legged dragons regarded Xia Fan as their "own dragon", and they were also "young dragons", and they were very kind to him. The adult cross-legged dragon "understood" what he meant, and immediately ran wildly along the rocks. The two giant legs ran, and every time they landed, there was a loud "boom" sound, which shook the surrounding mountains and rocks.

Although the cross-legged dragon was not an agile beast, it was not slow, and after an hour, it finally came to the area where the multicolored halo was.

"Wow~~"

A mountain stream appeared in front of me, and the clear water meandered forward.

On the opposite side of the mountain stream, there are as many as eight pieces of jade, exuding brilliance of different colors.

Xia Fan stared at it carefully, and saw that the jade bi was mottled, with obscure fonts carved on it, and there were also human portraits on it.

After browsing it, his body shook violently, and he showed a surprised expression.

"These eight pieces of jade are divided into eight different colors: red, orange, yellow, green, blue, purple, and white, and each color represents a combat skill, a total of eight combat skills, corresponding to axes, hooks, forks, swords, spears, and whips. Every successful cultivation of each combat skill possesses extremely powerful power. ”

Xia Fan translated the Yaxing script on the jade bi, and his heart instantly became excited, and the flow rate of blood became much faster, and he felt like he had picked up a treasure.

On the current earth, I'm afraid he is the only one who understands the sub-star language. If you are someone else, even if you see the pictures and words on the jade, you don't want to refine the true meaning of combat skills. Because they don't understand Yaxing, they can only grope according to the pictures, and they will ignore many key points.

"I see, I see. In an instant, Xia Fan suddenly figured out a lot of things.

Why did the map lure the people of the Six Great Martial Arts Halls into the Valley of the Fallen Gods? Not just to make them fight each other, but also to put them to war.

And the prize is these eight pieces of jade.

Only the final winner can enter the depths of the Valley of the Fallen Gods and obtain the mastery of combat skills on the jade.

And there is no doubt that in this test, he relied on the dragon group to defeat the masters of various martial arts halls, and became the only person who was qualified to obtain the jade bi master.

"Hahaha, I didn't expect my luck to be so good. If Ke Jingyun, Bu Qi, and Qin Mingxiu knew the truth, they would probably vomit blood in anger. Xia Fan laughed wildly in his heart.

These three people, all of whom were at the peak of the seventh order of the Black Stage, were originally the most promising to obtain the qualification to participate in the Jade Bi, but they missed the opportunity because of Xia Fan's birth. What's more, they were not defeated by Xia Fan's strength, but were crushed by the group of cross-legged dragons at the mouth of the fallen god valley.

Think about how aggrieved you are!

However, thinking that the means of winning were a bit "despicable", he suddenly felt a little disappointed.

"No matter, since it's my chance, I can't miss it. ”

Thinking of this, he immediately raised his head, looked at the purple jade bi, and carefully read through the Yaxing text on it, lest he miss some key details.

The whole piece of purple jade records a set of combat skills called "Seven Bi Marksmanship".

If you want to understand this set of combat skills, you must first understand what "Bi" is.

According to Yaxingwen's description, Xia Fan vaguely felt that the so-called "Bi" actually referred to the sound barrier.

Sound barrier, also known as sound barrier, is a condition in which the speed of a marksmanship approaches the speed of sound, causing a sharp increase in resistance and making it extremely difficult to control the head of the gun.

Breaking the sound barrier is called "breaking the bi".

The core of the whole combat technique is how to break the sound barrier.

"Qibi Marksmanship, that is to say, when this set of marksmanship is cultivated to the extreme, it can reach a terrifying speed of seven times the speed of sound......" Thinking of this, Xia Fan suddenly gasped fiercely.

It's horrible.

What is the concept of seven times the speed of sound, even a bird, at seven times the speed of sound, can crash into a building.

"Earlier, I fought with the alder, and the gun speed reached the limit of 380 rpm, and at that time the entire burst musket was completely uncontrolled, as if it could fly away at any time, which should be the result of hitting the sound barrier. In that case, it was a fluke to strangle the alder. But I can't always be so lucky, if I can break the first of the Seven Marksmanship, and then face the Alder Beast, I won't be so embarrassed. ”

Xia Fan's heart was agitated, this combat skill was too powerful, if it was spread and the meaning of the sub-star text above was analyzed, it would definitely cause a sensation.

"Okay, let's put this technique to the test now and see if it can help me break the first sound barrier.

Xia Fan grabbed the exploding musket, the body of the gun of more than 100 catties was the same weight as a firewood stick in his hand, his wrist shook violently, and with a "snort", the spear suddenly bounced up, and instantly pierced into the trunk of the opposite tree, and a black hole with a big head immediately appeared in the entire trunk.

"No, the speed just now was only 280 rpm, and it was already out of my control, come again!"

Undeterred, he drew his musket and continued to stab.

When he practiced his combat skills, the genetic energy in his body turned into rolling energy, which was poured into the burst musket through both hands, making the burst musket faster and faster.

The speed of sound is 340 m/s, which means that the speed of the burst flame needs to reach more than 340 revolutions to break the sound barrier.

But the actual situation is that once the speed of the gun is close to 280 rpm, the entire gun body will become extremely hot after being infused with genetic energy, the gun head will shake violently, and the difficulty of control will increase exponentially.

Once, twice, three times......

Xia Fan practiced tirelessly, and the lifebridge in his body frantically absorbed the genetic energy around him, replenishing and consuming, forgetting the time and where he was.

When he was tired from practicing, he lay down on the rocks under the mountain stream to rest.

If you are thirsty, drink directly from the sweet spring below.

When he was hungry, he went to the tree to pick red wild fruits to satisfy his hunger.

This constant and crazy practice has made his marksmanship improve at an astonishing speed, 280 rpm, 290 rpm, 300 rpm, 310 rpm...... Progress again and again, but also breakthrough again and again, constantly approaching the limit of 340 rpm.

Rumble~~

I don't know how long later, an explosion-like loud bang suddenly sounded on the mountain stream, which shook the spring water under the entire mountain stream and instantly evaporated more than half, and a large area of water vapor evaporated and spread around.

"Whew~~" Xia Fan half-squatted on the bluestone, gasping for breath, but a satisfied smile appeared on his face.

He finally managed to break through the first sound barrier.

In other words, his gun speed can enter the space between 340 and 680 revolutions, and it is completely controllable.

It's a whole new realm.

"However, this purple jade is incomplete, and the breakthrough method of the higher-level sound barrier is all covered by the purple light, no matter how hard I try, I can't see the situation behind it. ”

Xia Fan was happy, but also had some small regrets.
