The old man who sold the black stone guessed correctly, there were indeed no large ice crystals in the stone, but he couldn't have imagined that it was actually a piece of Exercise Jade Slip!

Xiao Lici was a little shocked at first, and then his expression turned into joy, and he hurriedly picked up the jade slip and carefully confirmed.

He injected his spiritual power into it, and sure enough, a piece of information poured into his mind, and it was not only words, but also a picture, which should be a high-level martial art jade jian!

"Polar Ice Sword Duel?"

After reading the text message, Xiao Lici muttered to himself, and the joy on his face was a little more.

This Extreme Ice Sword is actually a very rare growth-type martial art, which can be cultivated in the Purple Mansion Realm, and the higher the level of the cultivator's ice power, the stronger the power it can exert, and there is no upper limit.

From this point of view, this set of martial arts seems to be a sword technique tailored for the people of the Ice Clan, and it is very likely to be the martial arts of the Ice Clan in ancient times!

After the catastrophe of the gods 100,000 years ago, the Ice Clan hurriedly retreated to the far north, losing a lot of resources, including many martial arts.

Xiao Lici didn't expect that he would actually find a set of precious ancient martial arts by chance, compared to it, the primary spirit stone spent was nothing at all!

If the old vendor knew that what was hidden in the stone was a piece of Exercise Jade Slip or a growth martial art, he would definitely regret slapping himself in the mouth, but even if he knew it now, it would be too late.

After Xiao Lici put the Xuanbing Jade Jane into the space ring and kept it, he left the inn excitedly. On the way, he bought some daily necessities for his outing, and then walked briskly towards the Fengyang Mountain Range.

The Extreme Ice Sword Duel made him a little impatient!

A few hours later, it was past noon, and Xiao Lici came to the outskirts of the Fengyang Mountain Range. He found a low bush that was quite spacious, and the Cold Light Sword appeared in his hand, and he directly began to practice the Extreme Ice Sword Duel.

Most of the people who haunt here are first- and second-order demon beasts, which are not very dangerous, and they are just suitable for sword training.

Extreme Ice Sword Duel is a martial art that condenses the Extreme Ice Sword Qi attack, and there are also five killable swords, and the picture in the jade slip is the explanation of the Killing Sword.

Xiao Lici did not go far and directly practice the sword of killing, but gradually started with the basic swordsmanship.

According to the content of the martial arts, he began to try to condense the Extreme Ice Sword Qi and control the cold ice spiritual power from the Purple Mansion to the Cold Light Sword. Blue light bloomed above the blade, and an icy chill spread around.

As the cold ice spiritual power continued to compress on the blade, the chill became stronger and stronger, until the energy was a little uncontrollable, Xiao Lici swung his sword forward, and a sword qi roared out with a chilling chill. But this sword qi began to collapse on its own before it was five meters away from the sword, dissipating in the heavens and the earth, and failed to condense!

Again!

He was not discouraged, and continued to practice, constantly compressing and condensing the cold ice spiritual power into sword qi and releasing it.

The second time it was five meters, the third time was five meters, and the fourth time it was still five meters, and it wasn't until the fifth time that the distance between the sword qi and the sword attack finally increased, and it began to dissipate after flying six meters.

Make progress and come again!

The boy made persistent efforts, constantly condensed, and swung his sword, as if he didn't feel a little tired, and enjoyed the progress in it.

It wasn't until after hundreds of attempts that he stood still with his sword, adjusting his breathing while sorting out the various problems that had arisen during the practice just now, and then turned around and slashed at the huge dead tree more than thirty meters away.

A cold sword qi that was already somewhat close to materialization suddenly came out of the sword, cutting the dead tree in half. But the top half of the dead tree didn't fall, because the place where it broke had been frozen by the force of ice!

This sword qi is full of power, and it has reached the level of purity of the Extreme Ice Sword Qi, and the foundation of the Extreme Ice Sword Duel can be regarded as a preliminary success!

"Whew, I'm so tired!"

The tiredness coming from his body did not hide the joy on his face, and after resting for a while, Xiao Liqi began to browse the explanation screen of the first move, the Killing Sword.

The first move is called a sword to break through the air. In the explanation screen, a light and shadow is holding a sword in his right hand, and the extreme ice sword qi on the blade is instantly condensed, as if it has been materialized, and it is extremely dazzling.

Then the light and shadow squatted slightly, and the power of ice flowed around his body, and the terrifying chill made Xiao Lici, who was watching the picture, feel a tingling bone.

The circulating power of ice seemed to isolate heaven and earth, turning a vacuum around the light and shadow body, and then his figure suddenly broke through the air, and rushed forward with his sword. His speed was extremely fast in that moment, and he would kill with one hit!

Such a wonderful picture is confusing.

This sword may seem simple, but it is actually extremely difficult. Only by combining movements, breathing, and specific energy movements can the forces of heaven and earth be isolated for a short period of time, and the body can become a temporary vacuum.

Moreover, it is difficult to condense the Extreme Ice Sword Qi at the moment of sprinting, so that the speed and attack power can reach the extreme!

After recalling the various details of the light and shadow sword, Xiao Lici tried it first. But the result can be imagined, there is no accident and the failure is miserable, which hurts him very much.

Increasing speed and condensing Polar Ice Sword Qi will clash with each other, causing the sword to fail.

After shaking his head, he had no choice but to continue watching the explanation, imitating while paying attention to various details. In this way, time passed slowly in serious concentration.

A few hours later, dusk came.

The boy in the bushes was still practicing, his blue robe was already soaked with sweat, but his sweaty face was not tired, but more and more focused.

"Break through the air with a sword!"

A loud shout sounded from the young man's mouth, and I saw him holding his sword and sprinting, his movements were exactly the same as the light and shadow in the explanation screen, without the slightest error.

Although a real vacuum had not yet formed around his body, his speed was still ridiculously fast, like a blue meteor streaking, piercing through a thick giant tree with a diameter of one meter with terrifying ice power.

"Bang!"

The trunk at the bottom of the giant tree was instantly frozen by the Extreme Ice Sword Qi, and then shattered in response, and was directly blasted into ice fragments flying everywhere.

"Whew, finally made it once!"

Seeing the giant tree behind him, Xiao Li exhaled a long breath, and a bright smile hung on the corner of his mouth. Although this kind of attack power is far from the polar ice breaking sky used by light and shadow, the power should not be underestimated, and coupled with the terrifying speed, it will catch the enemy off guard.

The only drawback is that the consumption is too terrifying, a few minutes ago he had just used his luck to restore his physical condition to the best, but after a sword, the cold ice spiritual power in his body had been consumed by nearly half!

"The first move of the killer sword consumes spiritual power so much, and the next four swords are not even more terrifying!"

Thinking of the next four moves of the killer sword, Xiao Lici longed for it, but then his longing became helpless, because with his current cultivation, he could only practice the first move!

"Alas, forget it, let's go to the actual battle first to try the power of a sword breaking through the air!"

Shaking his head, Xiao Lici no longer thought about the killing sword behind him, got up and walked towards the depths of the Fengyang Mountain Range. He doesn't plan to return to Fengyang City in the past few days, he must improve his strength as soon as possible before the atmospheric luck comes, after all, grasping that glimmer of life is the most important thing now!
