Facing Ye Feng, Zhang Sanfeng did not spare his hand a little.

Between the hand-raised, a fierce wind gathered.

The wind gathered into a dragon, and the wind dragon roared towards Ye Feng.

"Control the elements to attack?"

Looking at the wind dragon that attacked him, Ye Feng smiled while dodging, "You seemed to have a different feeling about the wind back then. ”

Ye Feng still remembered that when he was still in the yang world, Zhang Sanfeng once controlled the wind to attack him.

It's just that the wind at that time was much weaker than it is now.

"Heaven and earth are naturally connected, even in this underworld."

Hehe, Zhang Sanfeng floated in the air under the action of the wind, and then raised his hand to condense the wind dragon again, and now the wind dragon that is more than ten meters long is now being dealt with, and dozens of faint and faint appear in the air at this moment.

Qi Qi aimed at himself and roared.

Don't underestimate these wind dragons, not only the fury of the wind, but the wind blade hidden in it is extremely sharp.

The wind dragon was wrapped in a tornado, surrounding Ye Feng, and the powerful wind seemed to tear him into countless pieces.

"Definitely!"

In the wind, Ye Feng felt it seriously, and now Zhang Sanfeng's strength may be similar to the black dragon he fought with Ye Huang back then, and it may be worse than the black dragon.

According to the level of the underworld, the black dragon of that year should be the third grade.

Zhang Sanfeng is only close to Sanpin now.

This kind of power still doesn't pose a threat to Ye Feng.

With a soft snort, the entire space seemed to stand still in an instant, and those crazy tornadoes actually collapsed on their own.

Ran Zhou exploded directly on the spot and dissipated into invisibility.

In the sky, Zhang Sanfeng, who was originally stepping on the wind, suddenly felt that the wind under his feet was no longer under his control, and his whole person was falling unconsciously.

Fortunately, Ye Feng did not attack in the process, allowing him to land safely.

"Just now, what kind of ability is that?"

"Domain?"

Zhang Sanfeng was not surprised by his defeat, and in his opinion, this was normal.

It's just that he doesn't understand Ye Feng's power a little.

Why did the wind suddenly dissipate, how did the space suddenly stand still.

"In the array realm, I am temporarily integrated with this space, and the inscription in my body affects this space, and to a certain extent, I am the master of this space."

Strength is a very complicated thing, Ye Feng just explained it to Zhang Sanfeng briefly.

"Inscription."

Touching his chin, Zhang Sanfeng understood what Ye Feng said.

"Can I write an inscription then?"

"Also, how do you line up the inscriptions in the flesh?"

Asking for advice with an open mind, Zhang Sanfeng felt that Ye Feng's realm was really practical and very powerful.

It is more valuable for research than the simple realm of the three grades in the underworld.

"Take innate qi as the core." Ye Feng looked at Zhang Sanfeng and said.

"Well, when I didn't ask." Zhang Sanfeng shook his head slightly.

When he returned from the resurrection, he was not born in this underworld.

This is also the essential difference between people in the underworld and in the yang.

Both sides look the same, and even the genetic sequencing may be the same, but!

The basic materials that make up genes are not the same.

"Actually, I'm quite curious about this."

Ye Feng said softly, "Even if your body doesn't have an innate qi, since you have this body, you will inevitably have the most basic substance. ”

"But I haven't found the core base substance deep in your body."

"That's why I've said it, in fact, we're probably at the mercy of others." Zhang Sanfeng said with a smile.

"According to my reasoning over the years, we are able to live, most likely because of a very powerful magic weapon, nothing more."

"Maybe."

Bowing slightly, Ye Feng didn't say much.

He just felt that there were really a lot of secrets in this underworld waiting for him to dig further.

"Okay, let's not talk about that, let's go see the Great Wall first."

After a short discussion, the two began to hurry.

They all relied on flying, but even so, it was only two days later that the two arrived at the location of the Great Wall.

"This underworld is really big!"

Ye Feng was quite emotional.

According to the flight speed of the two of them, they have basically circled the earth in the past two days.

And such a distance is only the distance from the central area of Xudu to the remote areas.

And!

It's just an area of the whole underworld!

Outside, there are not only thirteen underworld cities, but also endless unexplored areas.

"It's huge, indeed."

After Zhang Sanfeng heard Ye Feng's emotion, he bowed slightly, "But I don't think the distance here can be completely compared to the yang world." ”

"Because the environment isn't exactly the same."

"Including gravity and so on."

"Makes sense." Nodding, Ye Feng agreed with Zhang Sanfeng's analysis.

After speaking, Ye Feng no longer continued the topic, but looked at the city wall in front of him.

Left and right, you can't see the end at a glance.

Up and down, you can't see the end at a glance.

To the touch, it feels like the same material as the Great Wall of the Sun, all of which are green bricks, but!

Ye Feng could clearly feel that there was a very peculiar energy fluctuation on it.

This energy fluctuation is contained in every brick.

And these countless masonry are connected together, and this energy fluctuation is perfectly connected.

Randomly tapped it.

The fact that his own attack power spread across this city wall and spread out is no different from tickling.

"Such a powerful formation, it can radiate such a long distance, how can it be done."

Just now, at that sudden attack, Ye Feng clearly felt that his attack power was evenly divided within all the blue bricks that he could perceive.

As for the outside of the perceptual range, I'm afraid the same is true.

"I don't know how, but it's a miracle."

"Just like the Great Wall of the Sun, it's also a miracle."

Stroking the city wall in front of him, Zhang Sanfen sighed.

"No one in the whole underworld knows how this wall was built."

"It's so high, a hundred miles high, it's unimaginable."

It is not the first time that Zhang Sanfeng has come here, but every time he comes, he has a feeling of spiritual shock.

"Speaking of which, do you know how high the heavens are in this underworld?"

After hearing Zhang Sanfeng's words, Ye Feng couldn't help but raise his head, wanting to see the height of the city wall clearly.

In the sun, a hundred miles in the sky, that means at least 50,000 meters, what is the concept of 50,000 meters in the sky?

It looks like it's about to break through the troposphere!

"How do you get up?" Ye Feng asked Zhang Sanfeng, "Besides, doesn't this city wall also have a city gate?" ”

"There are no gates."

Zhang Sanfeng nodded, and then said, "As for how to go up, there are two ways. ”

"The first way to fly up, but when it reaches an altitude of 10,000 meters, there will be an attack that lands, and the attack does not distinguish between the enemy and me."

"The second is the space circle, but you need a pass, but I don't have a pass."
