One sand dune after another slowly rose, and even Su Fan's feet gradually began to bulge.

"What is it this time?" Jiang Yihuan was taken aback and hurriedly dodged, and the four of them observed the sand dunes back to back.

In the blink of an eye, a huge city rising from the bottom of the desert appeared in front of everyone.

The walls are intricately carved and the quaint architecture speaks of the city's long history.

"Inexplicable......" Lu Xi didn't react for a while.

Only Su Fan stepped forward and reached out to touch the buildings beside him, frowned and said, "How do I feel that these walls are alive?"

At the moment when the city rose, Su Fan felt a vigorous vitality appear, these vitality was endlessly surrounding the surrounding buildings, if he hadn't seen it with his own eyes, he couldn't imagine that this was a city in the middle of a sea of sand.

"You're afraid you're stupid...... What kind of life can these hard and thick wall skins have?" Jiang Yihuan glanced at Su Fan, and did not take Su Fan's words to heart.

"But we are in the Void Palace, so we still have to be careful, Sister Jiang. Little Luo Ling said in time.

"But then again, it doesn't seem to be on the map...... It's like it came out of nowhere!" Jiang Yihuan said thoughtfully.

"It should be a formation, only when cultivators like us come here, this sand city will appear, and those machines that are exploring here by technological civilizations can't meet the conditions for triggering the formation, so there is no description. Lu Xi explained, and then added a sentence later, "Such a big formation is not a small one......

"It's possible that the key is in the middle of this sand city, but we still have to be very careful, I always feel that something is wrong here. Su Fan looked around, and then said with a slight worry in his tone.

Although he couldn't see the existence of any creatures, Su Fan, who had extraordinary perception, did feel the rich vitality around him, and there was a trace of demonic energy.

The four of them weave through the ancient city, but they don't find any clues about the key, but they discover something even stranger.

In the courtyard or in the house of every house here, there is always a table of sumptuous wine and food, and the most incredible thing for them is that the food is still steaming, as if it has just been served out of the pot.

Although Su Fan and the others could have long been exempt from eating grains, they still felt a little hungry when they looked at such a hearty delicacy back and forth.

"These meals are so weird, don't mess around!" Su Fan admonished, although he was also very persistent about eating, but in the face of this kind of food of unknown origin, the vigilance in his heart still kept him calm.

Jiang Yihuan, Lu Xi and Luo Ling are not stupid, they naturally know that these foods are very strange, even if they are very greedy, but they also hold back the restlessness in their hearts.

When he saw those meals, Su Fan also felt that the meals on the table also had the same vitality as those walled houses, just like living things.

The more Su Fan walked, he found that something was more and more wrong, because as long as the eyes could see, the area that his senses could reach, there were countless vitality, and Su Fan could still feel the trace of demonic energy mixed in these vitality.

"Have you noticed that there are so many similar small sand dunes here!" Su Fan pointed to the two or three piles of sand dunes in front of the house not far away, which were slightly higher than one person.

"After all, it's a desert, isn't it normal to have sand dunes, and on the other hand, it's even more unreasonable if there is no sand. Jiang Yihuan looked at it and said.

"That's right......" Su Fan nodded thoughtfully.

Time passed quickly, the sun had already set, and Su Fan and the others were still groping back and forth in the sand city, turning around for most of the day, but they didn't find anything.

"Could it be that someone else has already taken the lead here?" Jiang Yihuan put forward this hypothesis.

"It's not impossible, at least one team in each of the ten areas, and we haven't found any signs of other teams since we stepped here, so it's possible that the key here has been taken. Su Fan nodded, feeling that this was very likely.

"Wait, did you hear anything?" At this moment, Xiao Luo Ling motioned for everyone to be quiet, and then listened quietly.

"Shhh...... "It's like something is dragging on the ground, and then there's a constant low roar............ Although it was too dark to see what it was, the sound was chilling.

Jiang Yihuan opened his golden pupils and looked in the direction of the sound, and the next moment he covered his mouth and nose in shock, trying not to let himself let out a shocking scream.

Su Fan also felt a thick demonic aura coming from afar, and he didn't have to think about it, it was definitely a big demon who appeared.

None of the four spoke, so the monster only lingered here for a moment before fading away, and only after it was far away did everyone breathe a sigh of relief.

"What did you see?" Su Fan asked, although he could feel that it was a terrifying demon beast, he still couldn't understand what it looked like.

"Judging by Sister Jiang's reaction, I'm afraid that thing won't look too good!" Xiao Luo Ling said seriously on the side.

"It looks like a person, but it has snakes all over its body, and even five or six demon snakes coiled on its head are terrifying!" Jiang Yihuan said thoughtfully.

"It should be a demon beast that is about to approach the third order, let's not startle the snake, we still have to suffer against it. Su Fan said.

However, as soon as Su Fan's words were finished, a snake spitting snake letter stabbed directly at them like a flying sword thrown by someone.

Rumble!

Fortunately, Su Fan reacted quickly, dodged the blow, and after standing firm, they finally saw the snake demon covered in snakes that Jiang Yihuan saw.

I saw that its whole body was hidden in the cloak, but its limbs were all ruthless poisonous snakes, and there were not a few snakes coiled on its head at all, but every hair on its head was a long snake.

"It looks so disgusting...... Su Fan couldn't help but complain.

"Disgusting is disgusting, to be honest, I really don't want to fight with it......" Jiang Yihuan said with the disgusting in his heart.

"It doesn't look like it's very talkative, so let's play with it. Su Fan said.

"Roar ......!" the snake demon roared angrily, raised his two arms, and saw countless snakes coming out of his sleeves and killing Su Fan and them.

......Lu Xi stretched out the black-striped stick in his hand and swept most of the snakes down, and the soft sword in Jiang Yihuan's hand was also like a flower blooming in the night, countless sword lights bloomed, and those snakes were also cut off one by one.

"I don't think it's very powerful!" Jiang Yihuan said.

"Don't be careless!" Su Fan shouted.

Su Fan had no weapon, he had to get close to the snake demon to deal damage, and at the moment when the snake demon was dealing with Jiang Yihuan and Lu Xi, Su Fan came behind the snake demon with a jump.

Hit the back of the snake demon's head with a punch.

Su Fan, who originally thought that he could end the battle, found that his punch seemed to hit the cotton, and then saw that the head began to disintegrate, and then turned into a snake one by one.

"This ......" Su Fan was a little at a loss, but he still got up and retreated after this blow failed.

I saw that the disintegrated snakes condensed on that body again, and became a new head.

"Don't tell me this guy is made up of that disgusting dead man's snake all over his body!" Jiang Yihuan's scalp was a little numb.

"You should have guessed right......" Lu Xi on the side said lightly.

Xiao Luo Ling couldn't help by hiding behind them, there was too little water vapor here, and there was no way to gather into a wall of water as a defense.

"It's a little difficult...... Su Fan squatted on the top of a house and sighed.

"Hmm, there is some disorder, ......" Suddenly, Su Fan clearly felt that the breath of life in the surrounding houses and buildings had become a little disordered, chaotic and chaotic.

However, the demon snake didn't give them much chance to think, and jumped up directly towards Su Fan, just now Su Fan burst its head and completely attracted its hatred.

Su Fan and the demon snake were entangled together, and in the process of fighting, Su Fan also found that although the aura of this demon snake was infinitely close to that of a third-order demon beast, it was actually far inferior in attack and defense, and it was not even as high as the defense of the group of wild boar demon beasts that Su Fan encountered last time.

Although the combat power is not strong, it is very difficult, and if you are not careful, you will be entangled by the snake born on its body, and no matter how Su Fan attacks, this snake demon will eventually converge.

"Let's go help too!" Seeing that Su Fan was caught in a bitter battle, Jiang Yihuan and Lu Xi also joined the battle, but the situation was still indistinguishable.

No matter how they attacked, even if they were smashed by Su Fan, or cut off by Jiang Yihuan, or stabbed by Lu Xi, it would eventually return to its original state.

"Ahhh

But at this moment, the snake demon suddenly stood still.

Su Fan also sensed that something was wrong around him, and immediately motioned for everyone to leave this area.

"What's the matter, what are you running decently?" Jiang Yihuan asked.

"It just doesn't feel right...... Su Fan felt that the vitality in the buildings around him was getting stronger, and he felt like he was coming back to life.

Sure enough, in the next moment, those ancient buildings with the style of the Western Regions actually 'came to life'!

The buildings gradually changed color and then began to distort...... Lines appeared, and there were fine and cold scales on top of the lines......
