The passage was extremely long, and Chu Yan walked all the way, walking for about half an hour before he came to a stone gate.

With Chu Yan's arrival, the stone door slowly opened, and the dazzling light passed through the slowly opening stone door, and Chu Yan's eyes narrowed slightly.

A violent fluctuation of spiritual power rushed towards him, causing the true qi in Chu Yan's body to operate involuntarily.

This is a high platform, located on the top of the mountain on the quaint platform, a blue sword floating in the air above the high platform, floating up and down, around it, a whole nine thick thunder pillars, like towering trees straight into the sky, the sword arched in the middle, emitting a huge thunder and lightning explosion.

Chu Yan's face was shocked, and he looked at the nine thunderbolts in front of him and the sword with thunder all over his body with some surprise.

On the left hand side, a stone tablet was erected, and several rows of golden characters came into Chu Tian's eyes.

"If you want to pass the nine-day trial of thunder, you need to use the "Thunder Sword Technique" to cut off the thunder pillar!"

"Thunder Sword Technique?" Chu Yan saw a blue secret book on top of the stone tablet, and on it were the four big characters of "Lightning Sword Technique".

Reaching out to take off the secret book and an ordinary long sword on the stone tablet, Chu Yan gently opened the secret book and read it carefully.

"Thousands of miles of thunder flashes, comes like thunder, goes like electricity, flashes thousands of miles, flashes thousands of miles....refining to Xiaocheng, the momentum is like thunder, the sword is like thunder... Titled "Thirteen Swords of Thunder"

“……”

"It's such a powerful swordsmanship, it's actually just a yellow-level top-grade swordsmanship..."Chu Yan closed the "Thunder Sword Technique", held the long sword in his hand, closed his eyes gently, and the first style recorded in the secret book slowly appeared in his mind.

"Draw the sword... If you move, the sword moves, and if you move the sword, you will kill! This is a sword draw! ”

True air swirled and poured into the sword body, and with a slight shake of the wrist, the long sword let out a trembling sound.

"Qiang...."

Chu Yan's eyes opened violently, and he swept towards the twelve "Sword Test Stones" standing not far away, the long sword was unsheathed, and a sword light shot straight at the one-person high Sword Test Stone.

"Ding!"

With a soft sound, a puff of stone foam splashed out and dissipated in an instant, but there was not even a mark left on the test sword stone.

"Huh! What a hard stone... I can't hurt it in the slightest! Chu Yan frowned slightly, and muttered to himself, "Well, it shouldn't be fast enough, come again..."

"Boom..."

Draw your sword! Sheath!

Chu Yan's movements were completed in one go, but the result was still the same, only a trace of stone dust was splashed.

……

The Extreme Heaven Golden Dome "Thundering Nine Heavens" is located at the top of the third highest main peak of the Extreme Heaven Sect, which is closely connected with other main peaks by a series of suspended passages.

Layers of sea of clouds, magnificent, refreshing.

However, Chu Yan was not in the mood to appreciate it at this time, and his mind had all sunk into the "sword drawing style" of "Thirteen Swords of Thunder".

Draw the sword... Sheath...

Draw the sword again... Re-sheath...

I don't know how many times I repeated an action, and the sweat on my forehead became more and more.

"Ding..."

Another sword swing was thrown, and finally a small sword mark suddenly appeared on the sword test stone in front of him.

"Yes, yes, it's really the same as Bafang Po..."Chu Yan showed a look of surprise on his face, and then, his mind calmed down again, and his eyes became more and more fierce.

Five full days had passed, the sun and the moon above his head had alternated six times, and the sword test stone in front of him was densely covered with countless sword marks. Different shades, intertwined...

The sword drawing style of "Thirteen Swords of Thunder" has only one word, that is, fast!

Fast to the extreme, it is as powerful as a bamboo, and the strongest sword bursts out at the moment of drawing the sword, killing with one blow, never hesitating, and never looking back...

"Phew..."

"Click..."

The sound of the sword qi breaking through the air suddenly appeared, Chu Yan's sword was very different, and it slashed on the sword test stone, directly cutting out a scar that was an inch long and an inch deep.

The long sword in his hand was lightly snorted, Chu Yan smiled, and said

"It's time to try!"

Turning around, facing the high platform, the nine thunder pillars, lightning and thunder, the power was amazing, and the blue long sword in the middle seemed to feel Chu Tian's battle intent, and it actually made a buzzing trembling sound.

Facing the thunder pillar, the true qi in Chu Yan's body circulated rapidly, and the white tiger martial soul behind him rose up, appearing above Chu Yan's head, a pair of tiger eyes shining with golden light, looking directly at the nine thunder pillars in front of him, looking up to the sky and roaring.

"Draw the sword..."

His pupils shrank sharply, Chu Yan moved, and a sword swung out, and the white light sword qi that was amplified by the White Tiger Martial Spirit slashed straight towards the nearest thunder pillar.

"Phew..."

At the same time as the sound of breaking the air sounded, the white sword qi had already been deeply submerged in the thunder pillar...

But the stone sank into the sea, disappeared without a trace,

Just when Chu Yan was stunned, the thunder pillar suddenly rolled up, and a blue sword qi suddenly appeared, shooting straight towards Chu Yan...

Between the lightning and flint, Chu Yan drew his sword without hesitation, and the white sword qi left his body, colliding with the blue sword qi fiercely.

"Snort..."

Two groups of sword qi, one blue and one white, exploded not far in front of Chu Yan, and countless small sword qi shot out, several of which slashed through Chu Yan's ears and clothes, bringing out tiny blood marks and cloth fragments...

"It's so strong..."

"I didn't expect that I would refine this sword-drawing style to a small level, and I still not be the enemy of this thunder pillar's move... Could it be that this thunderous nine days really can't be cracked? ”

Frowning tightly, Chu Yan's eyes froze, and a hint of hesitation flashed.

"No... No, as long as it's a trial, there must be a way to crack it, and then come..."

Just a thought flashed, Chu Yan's eyes became firm again, and without hesitation, he drew his sword and slashed at the thunder pillar,

When the thunder pillar reflected back a sword qi, Chu Yan, who had been prepared, split out a sword qi and broke it...

So repeatedly, for a while, on the high platform, the sword shadow flickered, the sword qi was vertical and horizontal, and countless sharp sword qi filled the entire space...

Chu Yan didn't know how many swords he had swung out, his clothes were in tatters, and there were countless sword wounds on his body, each sword wound brought out a trace of blood red, although it was not deep, but there were too many of them, making Chu Yan look extremely terrifying, like a bloody man like a mad demon.

Chu Yan also tried to attack several other thunder pillars, but found that the results were no different.

After that, Chu Yan completely calmed down, specializing in swinging swords, attacking, and defending, completely immersed in the world of swords, every time he swung a sword and blocked a sword, Chu Yan would deepen his understanding of swords.

In particular, the blue sword qi coming out of the thunder pillar's body, sometimes fast, sometimes slow, sometimes tangible, sometimes intangible, completely unrestrained, made Chu Yan shake a lot.

"I see, water is impermanent, the sword is impermanent, the sword is born from the heart, and the heart comes out! This is the sword..."

Chu Yan, whose eyes were glazed, looked at the blue sword qi shooting towards him, and slowly, the sword qi actually became slower and slower, as if it was about to stagnate.

"Draw the sword..."

At this moment, the white light on Chu Yan's body was great, and the White Tiger Martial Spirit shot out a white light at the same time, merging with Chu Yan's sword qi, and slashing towards the blue sword qi...

"Ding..."

With a crisp sound, after the blue sword qi was broken in two, the white sword qi emitted by Chu Yan continued unabated, shooting straight towards the thunder pillar.

"Hum..."

The sword qi attacked the thunder pillar, bringing out a tremor sound, and the faint thunder rolled down, and the place where the thunder pillar was hit by the sword qi suddenly shrank a small hole, and it seemed to be completely pierced by the sword qi.

But in just an instant, it returned to its original state, and suddenly, it shot another blue sword qi to attack Chu Yan.

"Yes... That's it! ”

The corners of Chu Yan's mouth lifted lightly, and a faint smile appeared on his face.
