He remembered some previous memories in his heart, combined with some information from the Nine-Story Heavenly Tower, and came to a conclusion: "Could it be that this is the Artistic Conception Stone?"

With this thought, Lu Ling suddenly recovered a little surprise, and took out the smallest stone he had obtained initially, he had long been yearning for this kind of treasure, so he naturally looked up all the information that could be found, naturally, and the way to use it was also known, it was very simple.

He began to try to probe into it with his mental power, and almost instantly, he felt that something was present in the stone, ethereal.

"The artistic conception of fire;" Lu Ling was no stranger to this, and he recognized it at the first time.

He was immediately interested, but then he was disappointed, the breath of the artistic conception of fire in this is very weak, and the information involved in the artistic conception of fire is very superficial.

He estimated that even if this kind of artistic conception stone was used by a relatively talented person, it would not be enough for people to climb to the entry level, and a dozen of these stones were a little hopeful.

He tried to use his spiritual power to probe into the other two pieces, but they disappointed him, the best one, the artistic conception of fire in it was only a little bit of the intensity of the early stage of the first level.

Shaking his head in disappointment, his spiritual power retracted: "It turns out that this is the artistic conception stone, if I hadn't comprehended and mastered the second-level artistic conception before, they would be a rare treasure for me, now, they may make me some extra money and supplement my losses, but I don't know if this thing sells well;"

Knowing this, he was not interested in the stones, but he had to keep going, and now he was only on the fourth floor, and there were five floors to follow.

After a while, he came to the fifth floor, which already seemed very large, not like a tower at all, but more like a small square, and the aura was even stronger.

The first creature soon appeared, black as ink, tall and mighty, like an iron tower, with a hard tendon flesh full of explosive beauty, and every muscle was extremely solid.

On the top of its head, there are a pair of long meniscus-shaped horns, two long ears fluttering like a fan, eyes and nose are large, and a snort from time to time exhales is full of thick breath.

"Black Tower Demon Bull, a third-order consummate spirit beast, isn't it, there is already a faint aura of the fourth order;" Lu Ling exclaimed.

The reason why he knew this spirit beast was due to the time when he lived in Pang Ying's grandfather's place, where he read a lot of books, among which there was a page in a book that recorded some words of this spirit beast, and it was also accompanied by a portrait, which was the same as this spirit beast.

There is a sentence in it that says, the Black Tower Demon Bull can be regarded as the king of spirit beasts.

"Baa~"

A voice sounded, as terrifying as thunder, and Lu Ling couldn't help but squint his eyes.

"Interesting, it's a pity, if I hadn't broken through the Spirit King Realm Consummation, you would indeed be a rare opponent, but now, although I don't know your ability, you should be almost;"

As soon as Lu Ling finished speaking, he raised his sword and cut it horizontally, and a sword light struck the huge figure in an instant.

The Black Tower Demon Bull actually raised its front legs high, its whole body was shining with black light, and with a few thunderous screams, its hooves fell fiercely, and the ground around it actually trembled.

The point was that its powerful snort suddenly spewed out a black air stream towards Lu Ling's attack, accompanied by the power of that kick.

Suddenly, Lu Ling's powerful sword was completely disintegrated in an instant, and there was a powerful force that bombarded him.

"What?, dark attribute, this is terrible!" Lu Ling exclaimed, the life of the dark attribute, the first time he faced it, it was actually in this situation.

I didn't think about it, but this energy was too terrifying, and the speed was so fast, just a hesitation of breathing, he felt as if he had been hit by a 10,000-pound boulder in his chest, and the whole person flew out of the distance, and the corners of his mouth overflowed with blood.

The moment he hit the ground, he felt that the bones of his whole body were about to fall apart, and then looked at his chest, his clothes and everything had been destroyed, and the slightest corrosive black energy was still trying to invade his body, but unfortunately it didn't succeed, his physical defense was not weak, but now he also felt his internal organs churning.

Being taken aback by such a big startle, Lu Ling's face showed a strong battle intent and said: "Dark attribute creatures, this is the first time I have faced it, and my ability is a little beyond my expectations, but no matter how strong you are when you meet me, you are still killing yourself;"

As his voice fell, Lu Ling was just about to get serious, when suddenly, above his head, there was another phenomenon of aura converging, and it was two points of light condensing at the same time.

Lu Ling looked at the two phantoms that were getting clearer and clearer, his eyelids trembled, and he said with a speechless face: "No, it's just the fifth layer, so you have to play like this?"

Soon, two new Black Tower Demon Bulls appeared, and the three Demon Bulls stood together, their characteristics were completely no different in Lu Ling's opinion, but he knew that in the face of the three Black Tower Demon Bulls at the same time, he really had to be very serious.

While Lu Ling was observing the Black Tower Demon Bull, the three Black Tower Demon Bulls seemed to be looking at him with disdain in their eyes, which made Lu Ling even more cautious.

His heart tightened, and he muttered: "The spirit beasts that appear in this layer seem to not only increase in number, but also seem to have some wisdom;"

At this time, the three Black Tower Demon Bulls took a step forward at the same time and shouted loudly: "Baa~"

At the same time they lifted their feet and stomped the ground.

"Bang;"

The three Black Tower Demon Bulls were as unanimous as a formation, this kick was very terrifying, and the ground shook when they stomped on it, and in Lu Ling's induction, a powerful force immediately appeared on the ground and spread towards him.

Lu Ling was shocked, his legs kicked the ground and leaped up, and the sword light that had integrated into the artistic conception of the second-level fire "Boom" appeared at the same time, and three attacks towards the Black Tower Demon Bull.

The three Black Tower Demon Bulls snorted at the same time, each meeting an attack from Lu Ling, and the two collided, and what came into Lu Ling's ears was the sound of metal colliding.

At a glance, he sadly found that the snort of the Black Tower Demon Bull had indeed failed to stop his sword moves, but it was easily taken by their pair of big horns, and there was no scar.

Lu Ling's gaze tightened: "Another monster with a strong defense, this defense is no worse than the spirit beast of the previous layer;"

Lu Ling knew very well how powerful the damage caused by his attacks was, but he still couldn't cause a single damage to them, and he was surprised and a little puzzled at the same time.

I thought in my heart: "This is already the case with the fifth layer, so how perverted should the next four layers be? Moreover, these three spirit beasts, with the combined force, ordinary early stage martial artists of the Spirit Emperor Realm are estimated to be able to fight, does the Ziyang Empire have such a genius?"

In Lu Ling's current level, the perverted test of the Nine-Story Heavenly Tower, as far as he knows, is the strongest young generation he knows, that Lin Jun, and the fourth layer is estimated that he will not be able to pass it, but why would the royal family set up such a perverted test?

Without thinking too much, seeing that the three demon bulls began to move again, Lu Ling also restrained his mind.

"These three guys are not small when they work together, since this is the case, then I won't play anymore;" After Lu Ling finished speaking, the battle qi expanded, and a radius of 100 meters was shrouded, and the battle qi also made great progress in the improvement of his strength.

The three demon bulls felt the inexplicable pressure and screamed in unison.

Lu Ling's body emitted a red and green faint light, and the two kinds of light of the long sword in his hand surged, and the long sword suddenly rose from the fourth-order low level to the fourth-order high-level, and the color changed from fiery red to blue and red, and its power increased a lot.

In addition, the artistic conception of fire in the early stage of the second level and the artistic conception of wood in the middle of the second level were pervasive, and with the blessing of the battle qi, Lu Ling actually slowly rose.

The first time he used all his strength, Lu Ling suddenly had a feeling of arrogance in his heart, as if he could overturn the world with a wave of his hand: "It's so powerful,"

Lu Ling was feeling his own strength, and the Black Tower Demon Bull also felt Lu Ling's strong threat, and suddenly took a step, the rough body did not burden it, and the figure quickly flashed towards Lu Ling.

Facing a demon bull that was more than twice his size, Lu Ling naturally reacted immediately, but he didn't move.

At this time, in his eyes, the three demon bulls were no longer so powerful, as if they had shrunk many times, no longer so tall and mighty, but a lot weaker, when he saw the three demon bulls rushing to his eyes at the same time.

Suddenly, at this time, a loud voice hissed, stirring up bursts of invisible ripples in the air, and three sword lights slashed towards the Black Tower Demon Bull like a storm, close at hand, impossible to avoid.

The three Black Tower Demon Bulls showed fear at the same time, and they all used their big horns to meet the sword light, but they were cut into countless pieces in an instant.

"Boom, boom;"

"Baa~Baa~Baa~"

In the roar, accompanied by the only scream of the Black Tower Demon Bull, when the smoke and dust fell, the figure of the three demon cows finally dissipated.

But Lu Ling didn't mean to be happy, he began to ponder.

thought: "It's still not enough, since the imperial family has set such a test, it can't just be used as an ornament, then it means that someone can go to the ninth layer, and no matter how bad it is, it will reach the eighth layer, and I, who is already like this on the fifth layer, the ninth layer~"

Thinking of this, Lu Ling slowly put away the contempt for those geniuses in the empire in his heart, and at the same time confirmed that there must be many geniuses in the Ziyang Empire who are not known, and this kind of thing, very few people can know about it, he believes his guess, although he doesn't understand why he hides it like this.

What's more, this is just a Ziyang Empire, and above their heads, there is also a high, the so-called Shangzong.

The third wave of spirit beasts did not appear, but directly appeared that kind of purple energy, Lu Ling was not surprised, this layer, facing the three Black Tower Demon Bulls at the same time, if the interlocutor did not match the combat power of the early stage of the ordinary Spirit Emperor Realm, it was basically impossible to pass, if this was not over, it would really be powerful.

Lu Ling sat patiently on the ground and began to absorb purple energy, he tried all kinds of methods he could think of to see if he could speed up the absorption, but it was useless to try, he could only take his time in a regular manner.

One day, two days, it wasn't until the third day that Lu Ling opened his eyes leisurely and let out a long exhale.
