The endless swampy land exuded a wisp of fishy smell, and Nie Fan and the others quickly left the place and walked away into the distance at this time.

The sky-killing attack stimulated a gray-brown air current, and as soon as this gray-brown air flow appeared, it surged with an ancient aura, which made people feel like time was flowing.

Liliang of time wants to control it, it is difficult to ascend to the sky, every existence that controls time is not a terrifying existence, a little control of the power of time and space, once it is cultivated to the realm of Dacheng, then the small combat power will definitely make too many people's scalps numb!

Streams of gray-brown air rushed out of the swamp like green smoke.

Looking at the air flow above the swamp, Nie Fan and the others were all a little shocked.

The quaint air flow was gray-brown, and at this moment, wisps suddenly shot out from this swamp, and the four of Nie Fan suddenly rushed into the distance.

Puff, a gray-brown light rushed out of the swamp quickly, and Nie Fan and the others stood in the distance and watched all this quietly.

"Did you find anything?" Xiao Xiao looked at Killing Heaven suspiciously, this gray-brown luster was inspired by Killing Heaven, and Xiao Xiao also launched an attack before, but nothing appeared.

"I don't know, I just felt that my attack was dissipating as soon as it touched a seal, and then what happened. ”

Xiao Xiao looked at the killing sky speechlessly.

Nie Fan frowned and looked at the gray-brown light, at this moment, this is the ninetieth layer of the Void Sea, such fluctuations, I don't know if it will cause some unrelated monks to appear.

Once it attracted the attention of the mysterious old man, then this time Nie Fan and the others would not be happy, and the aura was slowly becoming stronger at this moment.

Ten minutes passed in an instant, but the gray-brown light did not stop, on the contrary, it still grew stronger and stronger.

"Someone's coming!"

Ji Tian looked at the south and said coldly.

"The big man killed someone!" said Killing Tian coldly.

Xiao Xiao nodded slightly at the big man.

Nie Fan didn't say anything, and the big man disappeared in an instant, and at this moment, Nie Fan and the three of them were still staring closely at the gray-brown light in the distance.

The area within a radius of about 1,000 miles is not small, and such an area has a gray-brown light, which makes Nie Fan and the others also surprised.

But the area is still expanding!

"Stand back!"

Nie Fan let out a low sigh.

Xiaoxiao, Killing Heaven was also quickly retreating, and Nie Fan, who was two thousand miles away, saw a terrifying blazing heat in the distance, and then saw the figure of a big man shooting rapidly.

"It's just a small shrimp of the Yuan Sage Nine. The big man said disdainfully.

Xiao Xiao glared at the big man, and the big man shrank his head and stopped talking.

"Remember, there are some innocent people who try not to kill if they can. Nie Fan whispered, the so-called human life is a matter of heaven, and everyone's life has the meaning of existence, but sometimes when it is time to kill, it is innocent people who must be killed!

If you want to step into a more powerful realm, you can't tolerate the slightest mercy, but you must not kill indiscriminately!

The big man nodded slightly.

This time, the big man did not show the slightest mercy, and directly killed the comer, which was a decision of Heaven Killer and a small one, and the secret here must not be revealed.

Time passed in a blink of an eye, and the gray-brown light directly expanded to a radius of five thousand miles, but at this moment, the gray-brown light no longer expanded, but it became more powerful.

The brilliant gray-brown light imprinted a gray-brown cloud on the top of the sky, and if you looked at it from a distance, you would really think that there was a gray-brown cloud with a radius of 5,000 miles.

Of course, if you are under this heaven and earth, you can feel the terrifying aura and fluctuations surging under the gray-brown clouds.

In the blink of an eye, three days have passed, and on the fourth day, a sound like waves sounded, and then Nie Fan and the others saw the swampy land with a radius of five thousand miles, and immediately began to rush upwards, and even poured down in all directions.

The mud mixed with the water body was rapidly used in all directions, and a huge depth appeared in the center, and this deep pit formed a terrifying whirlpool, throwing out the swamp mud in it rapidly.

Half a day later, under the shocked eyes of Nie Fan and the others, a huge city made of mud appeared in front of everyone's eyes.

The huge pit is about 10,000 meters deep, and within a radius of 5,000 miles is a huge deep pit, and in the middle of the pit is a gray-brown city.

The cliffs formed by the mud are 10,000 meters deep, and they are covered by a circle of gray-brown light, making it impossible for the mud to enter the ancient city.

Nie Fan and the others who saw this scene were dumbfounded.

"Mom, what kind of place is this, how can such an ancient city appear?" said in a small shock when he felt the desolate atmosphere emanating from the muddy ancient city.

Ji Tian frowned and said, "Someone has been here before. ”

Nie Fan was stunned.

"I felt the old man's breath. Killing Heaven whispered.

"Won't you?" said the little unwillingly.

Killing Heaven didn't speak, but pointed out, and suddenly a black light rushed out, rushing towards the gray-brown barrier, only to see that the gray-brown barrier was suddenly corroded by the black airflow, and a huge gap appeared.

"Let's go!"

Killing Heaven let out a low shout, and Nie Fan and a few people hurriedly followed, and then Nie Fan and a few people appeared in this ancient city.

But this place is as gray-brown as you can see from the outside, as if made of mud, and the ancient gray-brown hall is scattered in this ancient city, and the ancient city within a radius of 5,000 miles exudes a trembling atmosphere.

But there was not the slightest breath of life here, and if you think this ancient city is an empty city, it would not be located under the swamp.

"Since the old man has been here, there is a time limit for the appearance of this ancient city, so we must hurry up, if we really can't find the root of the yellow sky, then we will leave quickly, once this ancient city is going to sink again, none of us can stop it. Killing Heaven reminded seriously.

Nie Fan and the others nodded slightly.

"Search on all sides. Killing Heaven whispered.

Then Nie Fan and the four of them immediately scattered and headed in four directions, the ancient streets were extremely desolate but exuding a shocking ancient atmosphere.

This ancient city has existed for hundreds of thousands of years, but it still exists today, but there is not the slightest breath of life in it, and it has been opened a lot over the years, but there are many people who are greedy, did not drive it out in a certain period of time, and finally were stuffed here.

Seeing some of the bones that had died not long ago in the distance, Nie Fan also thought of the origin of these bones.

In this way, Nie Fan also began to rush forward.

Ten minutes later, Nie Fan appeared in front of a gray-brown pagoda that was only ten meters high, at this moment, Nie Fan stood in front of this pagoda and looked at this tower that looked ordinary, but at this moment, Nie Fan looked at this ten-meter-high tower solemnly.

Bang, just after Nie Fan stayed for three seconds, there was a loud bang, and suddenly the ten-meter-high pagoda exploded, and suddenly, a gray light rose to the sky, and it was also at this moment that the divine beads on Nie Fan's neck suddenly shot out purple gas!
