After Lin Yu listened to Mengdie's words, he immediately showed a look of surprise on his face.

"Awesome my butterfly!"

Mengdie gave him a strange look, as if she was looking at an idiot.

Lin Yu coughed dryly, and also felt a little embarrassed.

After all, the word butterfly is very similar to the pronunciation of a certain word.

He almost didn't say a word, and he was super reduced.

But the ancestor really doesn't deceive him, and there are people around him who are easy to do.

If Mengdie hadn't assisted him in secret, I'm afraid he would still be in the dark about the detection.

Although Lin Yu didn't know how Mengdie had left the back door in the strongest city of the Xuantian Continent's human cultivators, it was naturally a good thing for them now.

Before Lin Yu and the others were surrounded, Mengdie was already directing Lin Yu to follow the route she had drawn up to the location ten miles outside the city of the Empty Xuan City.

Although the Holy Land Alliance monks in the Empty Xuan City had guessed the location of Lin Yu and the others, when they felt it, they found that these two people were no longer there.

They tried their best to reorganize the encirclement, and they pounced again.

What made them even more aggrieved was that they couldn't search around.

Because their main task is to guard the Empty Xuan City, this is their first priority.

As long as the Empty Xuan City can be defended, it is only a matter of time before Lin Yu and Mengdie are arrested.

Just when they were still struggling with what to do, Lin Yu and Mengdie had already come to the city of Kongxuan City.

The walls of Kongxuan City are all made of incomparably strong gold crystals, and this material seems to have been newly researched in the past 10,000 years.

Lin Yu didn't know what kind of inspiration the smelting methods of alloy materials he had left for Li Xiangyun and Xu You before had inspired the two of them, he only knew that this golden crystal was more than three times harder than the hardest material he had encountered when he came to the future dream realm last time.

Moreover, Jin Jing can also rebound some spell attacks, and the spiritual power does not have much destructive power for it at all.

If you want to destroy it, you can only rely on brute force, but how difficult is it to achieve such a level in such a huge city?

"There's the entrance I left in front of me, but I haven't used it since the city was built."

"At that time, this golden crystal had not yet been developed, so I should be glad to say it."

Mengdie looked at Lin Yu with a somewhat complicated face and said.

She couldn't have imagined that one day she would need to use this method to enter the Void Xuan City.

What she didn't expect was that her purpose this time was to rescue Qin Ruyue.

Lin Yu looked at the rows of formations in front of him, and glanced at the dream butterfly on the side with some confusion.

"Didn't you just tell me about this?"

Mengdie also seemed a little embarrassed, she said with a stiff neck.

"Didn't you ask me then?"

Hearing this, Lin Yu almost spurted out a mouthful of old blood.

What do you mean I haven't asked you yet? Isn't this road what you are referring to, how can you forget this defensive formation?

Fortunately, Lin Yu and Mengdie came here in advance, and there was still time to crack the formation, otherwise this only opportunity would be missed again.

Lin Yu took a deep breath and took out Huanyu Ding.

The moment Huanyu Ding came out, there seemed to be a strange fluctuation in the space, which made Lin Yu feel a little strange.

However, Lin Yu didn't take these things to heart, and since Lin Yu got it, Huanyu Ding hadn't found anything that could break through its defenses.

Now that time was pressing, Lin Yu didn't have time to crack these formation mechanisms and the city wall in front of him one by one.

can only be held up by Huanyu Ding and forcibly break through!

"Lin Yu! What do you want to do?! ”

Mengdie was immediately startled when she saw Lin Yu flying towards 2 in front of her.

Is this kid crazy, although the front formation is said to be the back door that she specially left for herself, and the power is much worse than the city protection formation, but it is not something that a monk like him can resist?

"What to do? Naturally, they rushed in! ”

Lin Yu grinned, revealing a mouth full of white teeth, as if he was saying something sparse and ordinary.

"You...... Don't be impulsive, this formation is very powerful......"

Mengdie's face suddenly changed when she heard this, and she hurriedly sped up her speed, wanting to stop Lin Yu, but what she didn't expect was that after Lin Yu sacrificed Huanyu Ding, the speed was even faster and outrageous.

The speed at which she flew with all her strength couldn't catch up with Lin Yu at all, which made Mengdie couldn't help but feel a little shocked in her heart.

"Lin Yu, you ......"

Mengdie looked at Lin Yu's unhesitating look, and didn't know why her heart was a little sour, this guy really didn't care about his life and death for Qin Ruyue!

Even with her strength, she didn't dare to take it lightly when facing so many formations, but who knew that Lin Yu didn't hesitate at all!

However, what happened in the next moment almost made Mengdie's jaw drop!

I saw the phantom of a giant tripod outside Lin Yu's body appear, although those formations began to burst out with amazing power after being broken into by outsiders, but these attacks fell on Lin Yu's body, and they had no effect.

The attacks of those formations, whether they were aimed at divine consciousness or simple spell attacks, were blocked by the strange giant tripod phantom outside Lin Yu's body, and Lin Yu himself flew towards the exit of the formation unimpeded.

Mengdie was stunned, and her speed was a little slower, but she was also very human, and after a short shock, she immediately began to catch up, wanting to catch up with Lin Yu's figure.

It seemed that Lin Yu had also discovered that this formation had little effect on him, so Lin Yu was not as anxious as before, and his speed had slowed down a bit, so as to wait for Dream Butterfly to catch up.

If you don't wait for her, the spiritual power stored in the Huanyu Ding has almost been exhausted, and Lin Yu can break through these formations, but when the city protection formation is finally opened, it still needs Mengdie to take action in person.

The people in the Void Xuan City were originally paying full attention to the scene outside the city, but what they didn't expect was that the underground was rumbling, as if the earth dragon had turned over.

It's just that they have never had this kind of earth dragon turning over in Zhongzhou, which makes them all a little surprised in their hearts.

However, in the next moment, two figures, a man and a woman, immediately flew out of the ground, and then rose into the sky!

Take a closer look, who else could it be if it wasn't Lin Yu and Mengdie?!

After Lin Yu came out of the ground, he turned his head to look at Mengdie, but found that there was something wrong with her face.
