Su Tong stepped into the secret realm, his body suspended above the void, and it was pitch black all around, and there was not even a place to stay.

I don't know why here, he relied on his spiritual power to probe the surroundings, but he found nothing.

"It's weird! Why is there nothing on this fourth floor? And even my psychic probes have been cut off."

Su Tong frowned and muttered, "I don't know, what is the test of this fourth layer."

"Buzz!"

The dark starlight around him, Su Tong was in the sea of stars at the moment, like a small grain of sand.

"Where is this?" Su Tong looked around in a bit of a panic.

Then, a familiar voice came from his ears: "The fourth layer of the rookie list of Kunlun Mountain, with the help of the power of the stars around it, condenses its own spiritual energy stars, and the trial time is ten days."

"Ten days? That's not right! There is a purple belt promotion contest on the ninth day!" Su Tong exclaimed.

At this moment, Jing Zhi's voice came from the Nine Tribulation Sword: "Master, this fourth layer provides the trialists with natural star power, this is a great opportunity! If you take advantage of this opportunity to greatly improve your spiritual energy level, it will not be too late to compete for this purple belt promotion competition again!"

"But ......"

After Su Tong's psychological struggle, he sighed lightly: "Forget it, if you come, you will be safe!"

"Master, hurry up and take out that Xuanlei Baolian, this will be of great benefit to you in condensing the aura stars!"

Su Tong did what Jing Zhi said, sat cross-legged on the Xuanlei Baolian, activated the aura in his body, and his hands quickly sealed.

"Buzz!"

A dull thunderclap sounded, and dazzling white thunder light emerged from Su Tong's body, and countless thunder snakes wound up, helping Su Tong absorb the power of the stars around him.

Su Tong's eyes were tightly closed, carefully feeling the changes in the void around him, he suddenly stretched out his arms, sank into the dantian, and wrapped the power of the stars around him, gathering in the palm of his hand.

The power of the stars surged wildly, constantly rushing towards Su Tong, in order to make it more peaceful, Su Tong could only use the internal exercises to suppress it with all his might.

"Whew! It's finally done!"

It took a lot of effort to condense this aura star.

Su Tong wiped the sweat off his forehead, took a deep breath, and said, "It's too hard to condense this aura star!"

Jing Zhi controlled the Nine Tribulations Sword to fly out of the scabbard, he wandered around, constantly observing the surroundings, and slowly spoke, "The structure of this fourth layer is so mysterious......

"What's wrong? Jingyuki, did you find anything?" Su Tong hurriedly stepped forward and asked.

Jing Zhi said meaningfully, "You first generation of ancestors are not small! This is not something that ordinary people can understand."

Su Tong asked puzzledly, "Jingzhi, what do you mean by this?"

Jing Zhi's spirit body landed beside Su Tong, and pointed to the stars around him and introduced, "Master, you see that there are countless stars here, but how many are really dazzling?"

"I'll take a look at ......"

Su Tong looked up at the sky, counted the twinkling stars in the sky, and replied, "There are twenty-eight."

Jing Zhi explained, "These twenty-eight dazzling stars are the twenty-eight stars of the ancients!"

"Twenty-eight nakshatras?"

Su Tong looked dazed, he was a typical guy who didn't learn and didn't know anything, Jing Zhi told him these professional terms, he naturally didn't understand. "The 28 Nakshatras are the 28 star regions divided by the movement of the sun and the moon, and are composed of seven Nakshatras each of the Eastern Green Dragon, the Southern Vermilion Bird, the Western White Tiger, and the Northern Xuanwu."

"In ancient times, the immortals looked up at the starry sky in the upper realm, divided the stars into several areas, called them the 28 houses, and divided these 28 houses into four houses according to the orientation: east, south, west, and north, each of which had seven houses, and imagined that the seven houses to which each house belonged were an animal, thinking that they were the four spirits of the heavens, and that they were in the four directions."

"The horns, the horns, the horns, the teeth, the houses, the hearts, the tails, and the kei, these seven constellations form a blue sky dragon disk

It is located in the east of heaven and earth, so it is called the Seven Nights of the Oriental Sky and the Blue Dragon; Fighting, bull, female, void, danger, room, wall, these seven stars form a group of turtles and snakes intertwined images, guarding the sky in the north, so it is called the seven houses of Xuanwu in the north; Kui, Lou, stomach, Pleiades, Bi, Mi, and ginseng, these seven constellations form the image of a mighty white tiger, entrenched in the western sky, so it is called the seven constellations of the western white tiger; Wells, ghosts, willows, stars, zhang, wings, and zhen, these seven constellations form the image of a flaming phoenix, shining on the southern sky, so it is called the Seven Houses of the Southern Burning Sky Vermilion Bird."

Jing Zhi patiently explained to Su Tong, although Su Tong was a little slack in his studies on weekdays, but listening to Jing Zhi's words, he took what he said in his mind very seriously.

"Do these twenty-eight nakshatras have any effect on this fourth-level trial?" Su Tong asked suspiciously.

Jing Zhi pinched a finger towards a star, only to see the bright star hanging in the starry sky flickering slightly, and the majestic aura around the star surged towards Jing Zhi madly.

"Since it is to use the power of the stars to condense the aura and stars, then it is natural to resonate with the twenty-eight stars in the sky to achieve the best effect of absorption and condensation."

Su Tong suddenly realized and exclaimed, "I see!"

This time, according to what Jing Zhi said, Su Tong held the Nine Tribulation Sword, and the sword light surged and pointed directly at the Seven Stars of the Green Dragon, and the starlight surged between the seven stars, and one after another meteors flew out and smashed towards Su Tong.

"I'll go! Why are you still playing this?"

The meteor came quickly, wrapped in majestic flames, and smashed towards Su Tong.

While maintaining the resonance between the Nine Tribulation Sword in his hand and the Qinglong Constellation, Su Tong kept dodging the Xuantian Shadow Step.

"Buzz!"

As the seven stars of the green dragon flickered one by one, a majestic power of the stars converged into a strong tidal wave and poured into Su Tong's dantian.

"Is it okay?"

"It's still early! There are three other constellations!"

Su Tong followed the previous method, and when he touched the White Tiger Constellation, countless white rays tore through the void and swept over, like lightning flying out. Seeing this scene, Su Tong had to free up one hand to resist the domineering light cut in front of him.

"Roar!"

A tiger roar sounded, and the seven stars of the white tiger above his head burst out of dazzling white light one by one, and the power of the stars surging around the white tiger turned into a huge white pillar of light, slowly rushing down from the top of Su Tong's head.

"Xuanwu!"

Su Tong roared, turned the spiritual power in his body and struggled to support it, and the seven stars of Xuanwu lit up, and one after another ghostly phantoms swept into Su Tong's body, and the afterimages around him swept around, containing extremely mysterious power.

"Suzaku!"

Su Tong roared wildly, only to see that the Vermilion Bird Star had changed, and the white star suddenly turned blood red, which couldn't help but make people's hearts tremble.

I saw the fierce force of the seven stars, and the flames rushed to the sky, turning into a Vermilion Bird Fire Shadow, and the huge flame wings slapped violently, rolling up a wave of flame qi.

"What a force! I can't stand it anymore......

Su Tong held the Nine Tribulation Sword tightly with both hands, and the powerful immortal fire invaded madly, and the Nine Tribulation Sword Body in his hand was burned red, and the blazing heat from the palm of his hand made it difficult for him to hold the hilt.

Jing Zhi looked at the blood that kept overflowing from the corners of Su Tong's mouth, and at the same time pinched a handful of sweat for Su Tong, and said anxiously, "Master, you must hold on!"

The immortal fire continued to destroy and tear Su Tong's body, the sword qi surging around was swallowed up by the flames that erupted, and the thunder and lightning that emerged on the skin fused with the flames, constantly colliding, and the crazy spiritual power continued to attack.

"Dingding!"

Su Tong's head was blank, and a familiar figure slowly rose in front of him, the man slowly stretched out a hand, and suddenly burst out a red gold flame, the two flames collided and intersected, constantly melting and dissipating, turning into sparks scattered in all directions.

"Phoenix Flame ......"

I saw the two most powerful flames in the world clashing, and Su Tong was under the powerful impact, his head sank violently, his limbs were weak, and his feet were weak

Empty.

Su Tong's legs weakened, and he fell to the ground with a "plop......

By the time Su Tong woke up, the immortal fire in front of him had already dissipated, and he saw that the fire spirit treasure fan was suspended in mid-air, and the flames were surging.

Su Tong slowly stood up under the support of Jing Zhi, and he looked up at the Vermilion Bird Seven Stars flashing with dazzling white light at this moment.

Jing Zhi slowly spoke, "Now that all the twenty-eight stars have returned to their positions, the master can begin to condense the aura stars."

Su Tong nodded, then sat cross-legged on the ground, his hands quickly sealed, pinched out the spell, and silently recited the incantation in his mouth.

"Green Dragon!"

I saw that a deafening dragon groan sounded, and the seven stars of the green dragon lit up violently, and a meteor crossed between the seven stars.

"Condensation!"

Su Tong used the aura in his body, introduced the power of the stars into his body, and exerted his magical powers, condensing the power of the stars into a bright aura star.

The aura stars condensed by the power of the stars in the fourth layer of this secret realm are more powerful than the power contained in the ordinary aura stars, and their aura is also more pure and majestic.

"White Tiger!"

Su Tong's handprint changed rapidly, and he saw a white strong light behind him violently swept up, and then turned into a huge white tiger that was extremely powerful, looking at the world like a king.

"Condensation!"

The power of the stars burst out, and Su Tong took the opportunity to make a move, running the Pure Yang Decisive Technique, and the Phoenix Flame immediately shrouded down, trapping the power of the stars in it.

"Xuanwu!"

I saw that the Xuanwu Seven Stars first flickered faintly, and then burst out with a strange strong light, and the power of the stars surged like a tide, looking from afar as if it was an ancient divine beast at work, that roar shook the earth, and the earth shook between raising his hand.

In the face of such a surging power of stars, a faint luster appeared around Su Tong's body, and the extremely powerful sword qi immediately burst out, the sword qi was entangled, and one after another extremely sharp sword light appeared.

"Suzaku!"

At the moment when the Seven Stars of the Vermilion Bird lit up, the monstrous immortal fire erupted, and tongues of fire erupted one after another, like a fire phoenix burning the plain.

This time, Su Tong had already prepared the Fire Spirit Treasure Fan, and when the immortal fire approached, he would use the Phoenix Flame to fight against it.

Right now, all the twenty-eight stars were subdued by Su Tong, and the power of the stars around him continued to pour into his dantian.

Su Tongpan sat in the void, meditated, and used the aura in the dantian to transform all the absorbed star power......
