The moment he entered the fourth layer, Lu Yun's first reaction was to investigate the surrounding environment.

It was still a wasteland, with dark clouds and mist covering the sky, and the field of vision had little visibility range.

So far, the environment in the first to fourth floors of the Vientiane Tower has been like this.

There was silence in the empty space, and the black mist slowly drifted as if the entire space on the fourth floor was slowly moving.

Dada!

Lu Yun slowly walked a few steps forward, and the sound of crisp footsteps echoed in his ears.

At this moment, in the darkness in the distance, a lantern-like red light suddenly appeared, almost a dozen pairs, Lu Yun glanced at it, and his right hand held the hilt tightly.

Woohoo!

The red lantern seemed to have spotted Lu Yun, and almost at the same time it began to move, approaching in his direction at a high speed.

After a while, the red lantern finally became clear.

A pair of scarlet fiery eyes, as well as that huge body, a powerful demonic aura emanated.

Monsters!

The demon beasts in the early stage of the second order were fifteen.

The momentum of each end was slightly stronger than that of the two ends on the third layer, and there were more of them, more than seven times as much.

In the middle of the general Tongmai realm, I am afraid that I am helpless, at most I will give up everything, and in the end, I will be able to die with a few of them.

But Lu Yun is different, so far, he has not really shown his strength.

He is a pure yang gang, and even he himself does not have an accurate grasp of how far he can reach after he explodes with all his strength.

"I hope you can hold on a little longer!"

Looking at the menacing and majestic dozen or so second-order early stage demon beasts, Lu Yun's eyes exhaled like arrows, the essence in his eyes flashed, and his powerful battle intent burst out.

"Sweep through a thousand armies!"

Lu Yun snorted coldly, the long knife was instantly unsheathed, and the cold light burst out, a knife light like a crescent moon burst out, and the black mist that was slowly fluttering around was directly cut, and the terrifying sword light slashed towards the attacking demon beast.

These fifteen demon beasts, not only are they huge in size and have strong limbs, but they are like thousands of troops rushing together, and their momentum is extremely fierce, giving people a feeling of invincibility.

However, after being slashed down by the incomparably bright, almost extended sword light, it was instantly crushed.

Lu Yun's figure flickered, and a sharp knife slashed at one of the demon beasts.

Bang!

The beast's strong front paws lifted and collided with the long knife that slashed down.

Click!

Blood was sprinkled all over the place, staining the pitch-black mist red, and then turning into a little red light, dotting the entire pitch-black sky.

With one successful blow, Lu Yun's feet were like flying, and the sword flashed.

After the explosive power, strength, and speed all burst out, the momentum of the whole person increased greatly, and it was not inferior to the demonic demon beast in the slightest.

Snort, the sword light tore through the darkness, vertical and horizontal, and landed heavily on another demon beast, instantly splitting it into bits of energy, floating in the dark sky, adding a few red rays to it again, embellishing a strange environment of black and red.

Break through a thousand mountains!

Sweep it all in!

The third-rate sword technique has reached the place of transcendence in his hands, and it is no weaker than the second-rate martial arts that others have performed perfectly, and one demon beast after another has died on the sharp sword technique.

After about half a cup of tea, there was no demon beast in the fourth layer of the Vientiane Tower.

Lu Yun stood with his sword in his hand, his qi and blood were slightly agitated, and he silently looked at the scarlet scene in front of him.

"The Vientiane Tower is really not simple, only the difficulty of the fourth layer has been raised to such an extent."

Lu Yun sighed slightly in his heart.

He clearly knew that the reason why he had slashed more than a dozen second-order early-stage demon beasts so easily was mainly due to the fact that he had raised the Mixed Yuan Gong to the realm of Cave Truth, and his physical body had almost broken the limit twice, and his foundation was extremely strong, which made it seem relatively easy.

However, it also shows that the martial arts academy has strict requirements for its disciples.

If you don't have the strength of the middle or late stage of the Tongmai Realm, you can't think of passing through the fourth layer of the Vientiane Tower.

The fifth floor of the Vientiane Tower.

There are only five demon beasts on this level, but ......

The demonic aura and coercion of these two demon beasts were several times stronger.

This is a mid-second-order demon beast!

One of the black bear demon beasts was even more terrifying in momentum and coercion, almost reaching the limit of the middle of the second order.

Lu Yun knew at a glance that this black bear demon beast alone could crush the fifteen demon beasts on the fourth layer.

And in the fifth layer, in addition to the black bear demon beasts, there were also four second-order mid-order demon beasts that were not much inferior.

It can be seen that it is not very difficult to pass the fifth layer.

"It seems that it is a bit difficult to pass through this layer just by relying on the Wind Breaking Knife Method!"

The second-order mid-stage demon beast is stronger than the second-order early-stage demon beast in terms of strength and physical strength, and the knife in his hand is the most ordinary weapon, not much more powerful than a kitchen knife.

If it weren't used in Lu Yun's hands, if he used his dexterity and protected it with Gang Qi when fighting demon beasts, I am afraid that it would be completely scrapped on the first or second layer.

Glancing at the long knife in his hand, sure enough, there was already a shallow crack.

"Weapons are also part of strength, it seems that we will have to find a suitable weapon again for some time!"

Lu Yun withdrew the qi wrapped in the long knife, and with a click, the long knife shattered into two pieces and fell to the ground with a clatter.

Shaking his head slightly, throwing the other half of the blade aside, Lu Yun's heart moved, and a white brilliant light curtain filled his body, like a rising sun, illuminating the dark and silent world.

This is the nature of pure yang, the most rigid to the yang, the power is pure, giving people a sense of light and reliability.

"Roar!" The black bear demon beast roared, and the wide and thick bear paw slapped out violently, and the powerful momentum swept away, and the terrifying strength forcibly dispersed the black mist, and the aftermath was not stopped shooting towards the landing cloud.

After Lu Yun's body broke the limit twice, it was much stronger than that of the same year, about the same as a fourteen or fifteen-year-old boy, but at this time, it was not much bigger than the bear's paw.

In the face of that wide, thick and powerful bear paw, Lu Yun did not retreat, and also bombarded with one palm!

Bang!

The palms are facing each other, as if a sledgehammer and an egg are touching.

A sledgehammer is a real sledgehammer, unstoppable, but an egg is not a real egg.

The powerful blood qi and Xiao Cheng's pure yang true qi exploded at the same time, and the extremely powerful force bombarded, and the huge body of the black bear also burst out, and a black mark appeared on the thick and strong bear paw.

It was the mark left by the burning power of the pure Yang True Qi.

"Roar—"

Feeling the sharp pain coming from the bear's paws, the black bear waved its strong arms and slapped its chest vigorously.

With its slapping, the hair on its body stood upside down, and the demonic aura and coercion exuded from its body became more powerful, approaching the late stage of the second order more and more.

"Give me death!"

Next, Lu Yun shouted, and the vast pure yang qi suddenly erupted like a big river.

With this punch, he not only burst out with the powerful power of his body, but also covered all the pure yang qi on his fist, like a small sun.

The fist of terror, indestructible, unstoppable, destroys everything.
