Xu Feng looked at the humans in front of him, they were not infected by the demonic qi, and there was a faint layer of fluorescence around their bodies, faintly blocking the invasion of the demonic qi.

"Yes, I am a disciple of the Sword Swinging Sect." Xu Feng nodded and said.

"This senior, our base is there, it's better to go back to the base with us to rest first." A young man said, pointing to the back.

"It's good!"

Xu Feng urgently needed to understand the situation now, and when he heard that there was a human base here, he didn't panic to ask this group of people.

"In the base, there must also be disciples of the Sword Swinging Sect." Xu Feng said secretly in his heart.

Several people carried the demon beast, and the group took Xu Feng and flew towards their base.

……

Xu Feng originally thought that the human base here was just a place like a village or a probe spaceship, but he didn't expect that he would see a steel city in a valley.

The city is more than 4,000 meters long, more than 3,000 meters wide, more than 10 million square meters, the city wall alone, there are 12 meters high, 5 meters wide, the surface of the city wall, faintly emerge dense golden gods, a translucent light curtain, the whole city is enveloped.

The city was built in a mountain col, surrounded on three sides, and there was no gate, only one due north.

"This city is really big!" Xu Feng sighed.

Bigger than this city, Xu Feng has seen many people, but to build such a city in the Demon Domain, Xu Feng can imagine the hardships and difficulties involved.

And just the materials used to build this city are not ordinary, ordinary alloy steel, which is constantly corroded by demonic energy in the Demon Domain, or it will not be long before it will decay.

In front of him, the city uses a special alloy mined from the Demon Domain, which can resist the attacks of the master-level powerhouse, coupled with the unique defensive divine text, even the domain master-level powerhouse cannot cause damage to this city wall.

In the city, there are no high-rise buildings, only houses made of boulders or metal, all of which are low-rise buildings, and the highest is not more than three floors.

"Senior, we need to hand in the task, go along this road, about three hundred meters away, there is a gathering place for the disciples of the Sword Swinging Sect, you can go there." The girl who first recognized Xu Feng as the Sword Sect said.

Xu Feng nodded slightly, thanked him, and walked in the direction guided by the girl.

In this city, all the human beings exist, and Xu Feng found that most of these human beings are disciples of major sects, and they are all major sects, although they have not seen it, they have heard of it.

Soon, Xu Feng came to a small two-story building, which looked rough from the outside, and was all made of huge rocks.

Standing at the door of the small building, Xu Feng felt a familiar atmosphere coming from the small building.

"This is, Senior Sister?" A look of surprise flashed in Xu Feng's eyes. The Sword Swinging Sect was destroyed, Xu Feng had not seen a single person from the Sword Swinging Sect until now, and at this time, if he was able to meet his senior sister Xiahou Feng, there were many questions that could be answered.

Rumble~

There was a sudden roar in the small building, a stone window was directly shattered, and a fiery figure flew out of the window and appeared in front of Xu Feng.

"Senior brother, it turned out to be you, you, you didn't die?" Xiahou Feng's face was full of excitement, holding Xu Feng's shoulder, looking incredulous.

"Senior sister......" Xu Feng showed a wry smile on his face, Xiahou Feng's strength had even reached the domain master level, and it was also the peak of the ninth order of the domain master level, and the strength of her arms made Xu Feng a little unbearable.

"Okay, good, hehe, I didn't expect that the junior brother would also break through to the domain master level, not bad!" Xiahou Feng seemed to notice his gaffe, and took his hands back without a trace, and gently patted Xu Feng's shoulder with an admiring look.

"The world, what about Master and Senior Brother?" Xu Feng hurriedly asked.

Xiahou Feng's face changed, and he shook his head and said: "On the day of the Demon Domain invasion, the master was killed in battle, and Duanmuqin's whereabouts were unknown, and some people and I took advantage of the chaos to rush into the open Demon Domain Passage......

Xu Feng frowned, in three hundred years, too many things have happened, I don't know what the reason is, the number of demon domain passages has increased suddenly, many star fields have appeared demon domain channels, some star fields have even appeared more than one, the demons swarmed out, and the flames of war instantly burned the entire universe.

The star field where the Sword Swinging Sect is located, although only one Demon Domain Passage has appeared, but with the appearance of the Demon Domain Passage, there is also a universe-level starry sky giant beast, and it is precisely because of this giant beast that the Sword Swinging Sect was almost wiped out, and finally had to be forced to retreat to the Purple Blue Star Domain hundreds of thousands of light years away from the Sword Swinging Sect.

And Xiahou Feng took the opportunity to enter the Demon Domain at that time, and has been hunting the Demon Clan in the Demon Domain.

"We have only one purpose here, which is to hunt the demons, and only by killing these demons will they be powerless to attack our universe." Xiahou Feng gritted his teeth and said, "Only by killing the demon clan can I avenge my master!" ”

Xu Feng's brows furrowed, the area of the Demon Domain was extremely vast, almost the same size as the universe they were in, and many people believed that the Demon Domain was actually the other side of the universe they were in.

"Kill all the demons?" Xu Feng muttered to himself.

"That's right, kill the Demon Clan, of course, the junior disciple can also go out through the Demon Domain Passage and go to the Purple Blue Star Domain to meet the other disciples of the Sword Swinging Sect." Xiahou Feng said.

The Demon Domain Passage has become extremely unstable at this time, and it will appear at any time, but like the fixed Demon Domain Passage in the Shattered Spirit Star Domain, there is none, as long as the Demon Domain Passage appears, after a period of time, it will be automatically closed.

"Since Senior Sister wants to kill the Demon Clan, Senior Brother, I will accompany you to the end!" Xu Feng smiled slightly and said.

The Demon Domain is so big, it is simply impossible to destroy the Demon Clan, even if Xu Feng breaks through to the cosmic level, I am afraid there is nothing he can do.

"Xu Feng, this is not a matter of the two of us, nor is it a matter of the Sword Swinging Sect, but an undying war between humans and demons!" Xiahou Feng said with a serious face: "The Demon Domain Passage has suddenly opened, and more than a dozen star fields have already been involved, or it won't be long before the flames of war will burn throughout the entire universe!" ”

"How so?" Xu Feng said to himself, he didn't expect that the situation would be eroded to this extent.

Rumble~

At this moment, a huge roar suddenly came from the city wall, and the entire city began to shake violently, and the translucent light curtain in the sky also began to tremble violently!

"There is a situation, go, go to the city wall!" Xiahou Feng's face changed, and he threw Xu Feng a spar the size of a fingernail, but he jumped up and flew towards the city wall.
