At this time, the Black Iron City was already surrounded by the disciples of the sect, and these disciples each held a set of array flags, and under the sky, each set of array flags was a set of small forbidden annihilation arrays, and the ninety-nine sets were combined to form a set of large forbidden annihilation arrays.

The Great Forbidden Annihilation Array has been laid down, and the breath of the formation envelops the entire Black Iron City, but everyone can see that the black qi inside is constantly surging, changing into all kinds of hideous shapes, and there is a kind of terrifying energy that wants to be devoured, and it makes people feel their scalps numb when they look at it.

Not only that, these black qi were constantly corroding the range of the formation, Lin Feng saw that the disciples of the Fengwu Sect continued to play the spirit trick into the formation flag, increasing the power of the formation, but the range of the formation was slowly expanding, this was because the black qi had corroded the space of the formation, so it seemed that the range of the formation had expanded.

"Sect Master, Senior Sister Diao Chan. Seeing Lin Feng and Diao Chan coming, Xie Renjie, the sect leader of the Nine Seven One Three, hurriedly stepped forward.

Lin Feng waved his hand: "What is the situation now, can you control it?"

Xie Renjie's face was a little solemn, and he said respectfully: "Sect Master, the situation is a little not good, the effect of these black qi is too terrifying. ”

After speaking, Xie Renjie took out a magic sword and handed it over, Lin Feng took it and saw that the body of this magic sword had become pitted, just like after being rusted in the ground for countless years.

"Is this corroded by black gas?"

"Well, and it's only a temporary exercise, and this black qi can not only corrode the magic weapon, but even the spiritual energy, sect master, look at the following. ”

The black iron below has completely turned into a paradise for monsters, and there are no living humans, all of them have become monsters, these monsters roar and kill each other after eating people, the defeated are eaten directly, and after the victor eats the vanquished, the size becomes even larger and more terrifying.

The tallest monster is already ten feet tall, without a human form at all, and its body is full of flesh and blood and tendons, like skinned chickens, and some even have huge horns on their heads, and I don't know what kind of species they are.

Lin Feng frowned, reached out and grabbed the ground, and in Xie Renjie's careful words, he grabbed a monster.

This monster is very large, but its strength is actually not very good, it was grabbed by Lin Feng's aura and couldn't move at all, but there was a red light in his eyes, and he roared desperately at Lin Feng.

"Can you still understand human speech?" asked Lin Feng.

The monster didn't react, so Lin Feng didn't talk nonsense, and directly used the soul searching technique, but the monster's brain was a mess, and the memories that Lin Feng searched out were pieces of blood-red memories, and he didn't know what it was.

"I don't have intelligence, and I've become a monster who only knows how to kill and poke instinctively, which is a bit similar to zombies, but it's much more terrifying than the size of zombies, huh?"

A cloud of black gas suddenly floated out of the monster's body and floated towards Lin Feng, Xie Renjie and Diao Chan were shocked and wanted to stop in front of Lin Feng, Lin Feng waved his hand, indicating that there was no problem.

This black qi seemed to be conscious, floating directly towards Lin Feng and floating onto Lin Feng's body, Lin Feng felt that something wanted to drill desperately into his body, but unfortunately Lin Feng had an immortal emperor body, and his body was extremely strong, and the black qi couldn't drill into it at all.

"It seems to be a living thing..."After feeling it carefully for a while, Lin Feng grabbed this black qi in his hand, and the black qi rushed left and right in Lin Feng's hand.

"System, show me the information of this black gas. ”

The system uncle is still quite powerful, and directly gave a row of information.

Black Devil Worm: This is a low-level insect that lives in the Dark Devil Realm, and likes to parasitize and devour the most, because of the harsh environment of the Dark Devil Realm, the Black Devil Worm has a strong lethality to all creatures in the outside world, but the Black Devil Worm is quite afraid of flames.

"I'll go, is this really a living creature, and it's still a worm?" Lin Feng was surprised.

The black devil insect can't be seen with the naked eye and the primordial spirit, it should be a creature smaller than a cell, like the black devil worm in the black qi in Lin Feng's hand, there must be trillions.

"Afraid of flames?" Lin Feng decided to give it a try.

As soon as his mind moved, a cluster of Jindan True Fire appeared in Lin Feng's hand, and as soon as this Jindan True Fire came out, he vaguely seemed to hear a miserable low sound, and the black gas was burned completely by the Jindan True Fire.

Sure enough, he was afraid of fire, and Lin Feng hurriedly informed all the disciples present of the weakness of the Black Demon Worm.

Now the disciples don't need to arrange the formation, they directly sacrifice the Jindan True Fire and burn it violently, and the black devil insects in the Black Iron City were quickly burned, but these black devil worms do seem to have some wisdom, or instinct, and those black devil worms that are close to the spatial rift escaped back to the spatial rift early.

"Since you're afraid of fire, it's no problem, Xie Renjie, you go and extract a few leyline volcanoes and put them here, set up the formation, and don't let the black demon worms come out again." ”

Xie Renjie nodded yes.

Extracting the leyline volcano is incredible in the eyes of ordinary people, but for immortal cultivators, especially immortal cultivators in the distraction realm, this is a very easy thing, and a strong person like Lin Feng can easily take on several mountains.

Xie Renjie quickly moved several leyline volcanoes over and put them under the spatial rift, there was still magma flowing in the volcanoes, and some disciples of the Fengwu Sect escaped into the ground, opening up these volcanoes with the magma underground, so that these leyline volcanoes would not cool down.

The black devil worm died, escaped, and the humans in the black iron city who were parasitized by the black devil worm all died, and the death was particularly miserable, all of them became dry corpses, which was when the black devil worm was dying, and all the essence and blood in the body were devoured.

Looking at the dead city below, Lin Feng's heart was a little heavy, how long had it been, millions of people had disappeared like this, and what worried Lin Feng even more was that the Black Devil Worm was just some low-level insects on the other side of the spatial rift, and the low-level insects were so powerful, so what about the more powerful ones?

"Xiao Zhi, is there any information about the Black Demon Realm?" At this time, of course, Lin Feng had to ask Xiao Zhi that he must know the other in order to be invincible.

Xiao Zhi is indeed omniscient and omnipotent, and soon sorted out the information about the Black Demon Realm for Lin Feng, and after reading the information of the Black Demon Realm, Lin Feng felt that his heart sank to the bottom.

When it comes to the Black Demon Realm, it must be said that the Demon Realm.

In this era, the supreme lord of the epoch makes the rules, and the lord of the epoch ascends to the heavens, a place where even the gods cannot peep into it except himself.

Under the heavens of the world, there are two planes of the highest level, one is the divine realm, and the other is the demon realm, and the divine realm and the demon realm are opposed to each other, like the two sides of a mirror.

Below the god realm there are the fairy realm, the spirit realm and countless planes, these planes are generally more decent, while below the demon realm are the abyss and countless planes, all of which are negative.

The Black Demon Realm belongs to the plane below the Demon Realm, and its plane level is somewhat similar to the Spirit Realm.
