The two of them have been wandering in the endless plains, and after another ten days, they finally saw a different scene.

At this moment, on top of this endless plain, a huge city appeared.

"Boss, how can there be a city in this Endless City? Isn't that incredible? The Heavenly Demon Emperor looked at the huge city and said in surprise.

"Didn't you say that this place is forbidden? In the forbidden land, there was a city, but I don't know if this is a living city or a dead city. Fan Chen looked at the giant city and said in surprise.

Fan Chen was also shocked by that city, because, in this place, there are sky-devouring ants everywhere, and there will be a city, which can devour everything, and it is preserved in the mouth of the sky-devouring ants, how can Fanchen not be shocked?

"I don't know! I really didn't expect that there would be a city in this forbidden land, and I don't know who built this giant city, and on this endless plain, a huge city suddenly appeared, which was really shocking. The Heavenly Demon Emperor was also shocked by the giant city, and at this time, he said in surprise again.

"Let's go into the city and have a look." As he spoke, Fan Chen walked towards the giant city.

"Good!" The Heavenly Demon Emperor replied.

So, after the Heavenly Demon Emperor also answered, he also followed Fan Chen and walked towards the giant city.

After a while, they came to the city of the great city.

The walls of that giant city are thousands of feet high, reaching into the sky, and they are magnificent.

Later, they searched under the city wall, but they did not find where the city gate was.

"Boss, why is this city so strange? Only city walls, but no city walls? Why is that? The Heavenly Demon Emperor said suspiciously.

"How do I know! However, I can check the information on this wall. Fan Chen said.

Afterwards, Fan Chen checked the information of the city wall.

Walls of the Eternal City:

Durable: Eternal and undamaged

"Eternal and undamaged? I'll try it, will it be damaged. After checking the information about the city wall, Fan Chen muttered to himself.

Then, Fan Chen directly took the peerless sword and used all his strength to cut down the city wall.

"Boom!!"

Then, the earth trembled, as if there had been a magnitude 10 earthquake.

Soon, however, the shaking stopped, and apart from the many cracks in the ground outside the walls, the walls were not damaged at all.

"Hold the grass, so the cow? Lao Tzu's sword, can kill 10,000 level bosses, cut on this city wall, even a white mark, can not be left, Niu Bi, really special Niu Bi, worthy of being, eternal and undamaged attributes! Fan Chen said in surprise.

"It's no wonder that this giant city can be preserved intact in this forbidden place." Fan Chen exclaimed.

"Boss? What's going on? The Heavenly Demon Emperor said suspiciously.

"I didn't just now, I checked the attributes of this city wall, and the attributes of the city wall are eternal and undamaged, so I tried it to see if it was really indestructible." Fan Chen said to the Heavenly Demon Emperor.

"Oh, well, I see!" The Heavenly Demon Emperor said.

"As a result, you have also seen that the earth has been shaken like that, and there is not even a single white mark left on this city wall, it seems that the reason why this city can exist in this forbidden place is all because of this city wall!" Fan Chen continued.

"So what can I do? There is not even a city gate, are we going to fly in? The Heavenly Demon Emperor said.

"Yes, let's fly in, see that this city wall is only a few thousand meters high, it shouldn't be difficult to fly in, but I don't know, in this city, there is a forbidden sky formation or something." Fan Chen said.

"Oh well! Then let's try it, if we can't fly in, let's think of other ways! The Heavenly Demon Emperor replied.

So, the two of them rode the Vermilion Bird and flew upward.

They soon came to the top of the wall, and by this time they were able to see what was inside the city.

I saw that in the city, people came and went, and there were demons, demons, and human races.

"Boss, this is too shocking, why don't those demon clans eat it? The demons didn't eat the demons either! It's also weird. The Heavenly Demon Emperor looked at the scene in the city and said shockingly.

"Who knows? Don't you know when you go in? Fan Chen said.

"Let's go, fly in and have a look!" As Fan Chen spoke, he ordered Suzaku to fly towards the city.

"Bang!!" Suzaku slammed directly into an invisible barrier, and was dizzy from the impact.

The two of them were also affected and were almost thrown out.

"Damn, there is really a formation, I can't get in!" The Heavenly Demon Emperor scolded.

"I'll take a look, what's going on with this formation, as long as it doesn't have that kind of eternal and undamaged attribute, I can destroy that formation with a single sword." Fan Chen said.

Then, Fan Chen checked the invisible barrier.

Eternal Forbidden Sky Domain: Eternal Forbidden Sky Formation, which is within the range of the formation and cannot fly.

"Grass, I really guessed correctly, there is a forbidden space formation in this city, and that formation is still at the eternal level, and it can't be damaged." After Fan Chen finished inspecting the invisible barrier, he scolded and said.

"So what do we do? There is no city gate, and you can't fly in, and finally, in this endless plain, I saw an inhabited city, but I couldn't get in, which was too depressing, alas! The Heavenly Demon Emperor sighed.

"Don't worry, I'll figure it out." Fan Chen persuaded him.

Then, Fan Chen thought about it.

After a while, Fan Chen thought, "Let's try to see if the plug-in can break this formation!" ”

So, Fan Chen took the forbidden space realm as a target and used the second kill to see if it could work.

"Ding!"

"To permanently destroy the target, it takes 99,999 trillion in energy value."

"Temporarily breaking for 10 seconds requires 900 million energy values, and in less than one second, the energy consumption value is doubled."

After receiving feedback from the plug-in system, Fan Chen decided to temporarily break the forbidden space realm for only ten seconds.

Ten seconds was enough time for them to get in.

"There's a way, I'll break that formation for ten seconds later, and then we'll just go in." After getting the way in, Fan Chen said to the Heavenly Demon Emperor.

"Really? Boss, you are too powerful, you can break the eternal level formation, what a special cheat! The Heavenly Demon Emperor said in shock.

"Okay, don't talk nonsense, I'll move faster later, I'll put away this Suzaku, look at his dumb appearance, it feels very unreliable, let's fly in by ourselves later!" Fan Chen said to the Heavenly Demon Emperor.

Then, Fan Chen directly used the plug-in to break through the eternal forbidden space realm for ten seconds.

Then, Fan Chen and the Heavenly Demon Emperor quickly flew into the Eternal City.
