The ground was shaken by the power of Du Yun's knife.

The unconscious security guard was woken up and looked at the two zombies that were split into four pieces at his feet, and he was scared to pee on the spot.

Du Yun's evil knife was horizontal, put it on the man's neck, and asked coldly, "How many zombies are there in this underground base?"

The man's voice trembled: "I, I don't know, at least, there are fifty or sixty heads." And no, it's not just humans, it's animals. ”

"What animal?"

"There are many breeds, dogs, wolves and even tigers and lions. ”

Du Yun and Li Anna looked shocked.

This experimental base is simply crazy, using people and animals to do zombie experiments.

"Who is the mastermind?" Du Yun's eyes breathed fire, and he couldn't wait to immediately kill the man behind the scenes and cut it in half.

The man hesitated, but at the moment of life and death, he finally said: "Yes, it's Yun Shao." ”

"Which cloud is less?"

"It's Liang Yun of the Liang family in the capital. ”

Speaking of Liang Yun, Du Yun really doesn't know him.

But he knew the Liang family, and he helped Liang Xin escape from marriage at the beginning, and now Liang Xin and the ghost husband Junzhuang are walking together.

After getting the answer he wanted, Du Yun's evil knife fell, and the man perished on the spot. Although this person is not the mastermind, he knew that the metamorphosis experiment in the underground base did not report it, and even maintained law and order here, and killed him.

Suddenly.

There was a violent shaking of the entire underground research institute.

Loud explosions rang out from the depths of the corridor.

In each individual laboratory, there is the low roar of zombies, and the roars one after another make people's scalps tingle when they hear it.

"Oh no! Those guys want to blow up the base. ”

Du Yun ran out, but quickly retreated.

His guess was true, someone detonated the bomb, and the fire was already burning.

In the corridor dozens of meters long, a fire dragon roared, and the heat wave blew, making people feel as if they were about to be burned.

"Oh no, Brother Yun, let's run away. "Anna has already walked towards the dark passage.

Du Yun stood still, a fire ignited on his body, the fire dragon that did not explode was fierce, but it was like a barrier, isolating the scorching temperature of the basement.

"Brother Yun, let's go!" Li Anna said urgently.

"You go out first, find a safe place to hide, I'll contact you when I get out." ”

When Du Yun's words fell, the figure had already jumped into the raging fire.

Li Anna was so frightened that her eyes fell to the ground, such a big fire, people can only die if they go in, but thinking of Du Yun's extraordinary ability, Li Anna can only grit her teeth and leave, she knows that she will become a burden if she stays.

In just one minute, the entire base was completely engulfed in flames.

Du Yun is like a burning man, walking in one laboratory after another.

Each lab is similarly constructed, with dungeons where zombies are kept, the walls of the dungeon are made of steel, they are built very strongly, and there are chains to trap the zombies in case they break free.

But after the explosion in the basement, most of the zombies broke free from the chain and rushed out, during which Du Yun encountered several zombies, but he didn't make much move, and those zombies were basically burned alive.

"It turns out that zombies are afraid of fire!"

Du Yun found a way to deal with zombies, and he saw several zombies rushing and roaring wildly in the fire, and finally burned to a black skeleton and fell to the ground.

Roar!

When I reached the end of the base, I saw a huge iron gate in front of me, and a deafening roar came from the iron gate.

Du Yun listened to the low roar of zombies all the way, and was very familiar with the sound in the iron gate, there was no doubt that there were zombies locked in it, and the roar was even stronger and penetrating.

Soon, there was a crashing sound at the iron door.

It should be that the things inside are crashing against the iron door, and every time it collides, the iron door has to shake violently, and even Du Yun, who is standing outside the door, feels that the soles of his feet are numb, as if there has been an earthquake.

When it hit the fifth blow, there was a 'boom', and two large iron gates more than three meters high collapsed, shaking up a ground of dust.

Roar, roar, roar!

More than a dozen black shadows burst out of the iron gate.

There are zombies that walk upright, hungry wolves that run fast, and even big roosters.

It was just a stunned kung fu, and all those things rushed towards Du Yun, with a faint green light bursting out of his eyes, and his aura was far more powerful than the zombies in the laboratory.

didn't have time to think about it, Du Yun raised his hand and stabbed.

Suddenly, the strength of the fourth layer of the True Spirit exploded, and the sword qi turned into a long black cloud, slashing a giant lion that was in mid-air to the ground.

The giant lion was not dead, a huge bloody hole was split on the top of his head, and green blood flowed.

When approaching Du Yun, one of the tall long-haired zombies suddenly waved his arms, as if a hurricane was rolling up, and slapped Du Yun out on the spot.

Du Yun's body flew more than ten meters away, knocked down the outer wall of a laboratory and fell into the ruins, before he could catch his breath, a black shadow flashed, it was the giant lion who had been struck by him before, staring at Du Yun in a downward posture, and the crack on the top of his head had already healed most of it.

Roar!

The giant lion roared.

opened his bloody mouth, and the corpse gas that spewed out was about to stun Du Yun.

Without waiting for the zombie giant lion to launch an attack, Du Yun slapped several balls of hellfire into its mouth, and then a violent explosion sound came from the giant lion's stomach, and the giant lion rampaged through the base like crazy, and finally hit his head and passed out bleeding.

finally leveled a stiffened lion.

But there are a dozen other animals and zombies coming in all directions.

These stiffened objects were black all over, almost merging with the night, and their eyes were flashing with an eerie green light, and the mere eye contact was terrifying.

"An evolved version of a zombie?"

Du Yun didn't understand the research situation of the experimental base, but he felt that this batch of zombies was far stronger than the zombies imprisoned in the laboratory, and their strength was comparable to that of a True Spirit Realm monk, and they had thick skin and thick flesh, and their defense was super strong, and ordinary True Spirit Realm monks had no way to take them.

Whew!

The fire of hell rises like a dragon in the midst of fire.

Aside from the Inferno Offensive, Du Yun had no better means, and his most powerful Divine Sense Offensive was useless against these zombie-dissolving things.

In an instant, the zombies with a single walking path were burned by the inferno, their footsteps stopped, their mouths let out a low roar, and their outstretched arms were bent up, trying to extinguish the fire on their bodies.

As for the stiffened animals, they were swift and leapt through the flames, leaving the inferno behind.

Du Yun immediately used the fire control technique, and the flames seemed to have eyes, chasing after the stiffened animals.

Speaking of this fire resistance technique, there are three layers.

Du Yun has only practiced the first layer of fire resistance now, and he can urge the trajectory of the flame to pursue the enemy.

When the fire resistance technique reaches the second level of transformation, it can transform the flame into various desired states to achieve unexpected results.

With the support of a powerful divine sense, Du Yun controlled more than a dozen infernos at one time, chasing several zombie beasts while beware of the zombie raid entangled in inferno.

This kind of operation is extremely difficult, and it is also a test for the current Du Yun, but as he continues to control the Hellfire, he gradually has a sense, as if he is one with the flames, as long as the mind flashes, the flames will change accordingly.

Swish!

When a new Hellfire is fired.

In an instant, it turned into a sharp sword more than five meters long and slashed into the air.

As soon as one of the zombies raised its head, the sword slashed down, blasting its head out.

The green liquid was sprinkled all over the ground, and a violent smell of corpses came out under the burning of the fire, Du Yun held his breath unaffected, and with the urging of his mind, a huge battle axe transformed into a hellfire split the sea of fire, cutting off a black panther that was jumping in mid-air.

The second layer of the Fire Resistance Technique has been transformed.

Du Yun's emotions of holding back his internal injuries were finally released, his mind flickered wildly, all kinds of inferno forms fell from the sky, and several flame beasts chased the zombie beast and roared.

The situation has shifted.

Du Yun began to gain the upper hand.

The entire underground base was set on fire, and all the buildings and equipment were burned.

Seeing that the batch of zombie dissolving things was about to be wiped out, a low roar suddenly came from the dark iron gate, and the roar seemed to come from the ground, hitting Du Yun's mind directly, and it shook his head with a tingling pain.

"Divine Consciousness Offensive?"

Du Yun's brows tightened.

Being able to release one's divine consciousness is at least a Holy Spirit Realm cultivation.

However, when Du Yun urged his divine sense to resist, he found that it had no effect at all.

This shows that it is not a divine consciousness attack, but an ordinary sonic attack, and Du Yun has already stepped into the fourth layer of the True Spirit, and his real strength can even compete with the strong venerable in the early stage of the Holy Spirit, if he can be injured by the sonic attack alone, it can be seen how powerful the thing hidden in the ground is.

Roar, roar, roar!

Just as Du Yun was thinking, a low roar sounded in his ears again.

This time, the roar was clearer and more thorough, and when Du Yun looked up, six figures walked out of the dark iron door.

The six approached, and the silhouette became clear.

It's not a human being to say it's a human being, and it's not like a zombie to say it's a zombie.

Their skin was dark, and their eyes glowed with a lilac glow, but the purple was mixed with some green light. He walks in the same posture as a zombie, but his hands are not straightened.

When they walked to a distance of one meter from Du Yun, the six people stopped.

One of them spoke: "Trespassers on the underground base!

Swish!

The man rushed suddenly, at great speed.

Du Yun just flickered at a thought, and his body seemed to be hit by a thousand catties of huge force, flying all the way, crashing through the walls of several laboratories before stopping.

"Can these zombies talk?" Du Yun was shocked in his heart, and he couldn't even care about his injuries for a while.

After the zombie struck, he was not in a hurry, and walked in the sea of fire, and even the inferno hit him without much effect.

Soon, the six-headed zombie appeared in Du Yun's field of vision again.

The six of them were lined up, their eyes were not sluggish, and they flashed with a faint sense of mockery.

"Damn it! The six of us are about to transform into purple corpses, you are here to make trouble at such a critical moment, if I don't refine you into corpse soldiers today, how can I relieve the hatred in my heart." The man spoke again.
