Ling Yun was a little confused at the time and thought to himself that it was just like that? That's that simple?

But now is not the time to think about these things. The key is that when the door opens, do you want to enter or not?

Ling Yun tilted his head and looked inside along the gap - it was completely black and could not see anything.

"Hey, is there anyone at home? Can I come in?"

Ling Yun shouted, but his voice was like a rock sinking into the sea, without even a sound.

The unknown world is terrible, but Ling Yun is not afraid.

After a little thought and without much hesitation, Ling Yun took a step in!

The fool didn't enter, the bronze giant gate just opened a gap. The terrifying dragon energy, emperor energy and yin energy were already dozens of times thicker than those outside, let alone inside the city?

That's not a hundred times a thousand times?

Not only is it thick, but also pure, so pure that Ling Yun feels extremely intoxicated. For Ling Yun, who has achieved great success in the Yin-Yang Art of Yi Qi, such temptation cannot be rejected at all.

Rumble...

Behind him, the sound of the bronze giant door closing sounded.

The protection formation was closed, and Ling Yun didn't care much about this. After he came in, it would be really abnormal if the formation was not closed.

Strangely, when Ling Yun was slashing the crack in the door, it was still dark. He could not see anything with his heavenly eye power and Yin-Yang divine eyes. But when the bronze giant door was closed, he could see things normally.

Inside the city, there is neither day nor night, and there is hazy gray everywhere within the sight.

At Lingyun's feet was a bluestone avenue dozens of meters wide, leading straight to the distance. He looked into the distance and could vaguely see the end of the avenue, as if it was a continuous palace.

Ling Yun looked back and found that the bronze giant gate was still there without any change.

His divine consciousness is still there and has not been any suppression, but within this city, he can only cover a range of 100 meters.

This is enough.

Lingyun had limited time and had no idea of ​​exploring this mysterious city. He remembered the purpose of his coming in.

After carefully observing the surrounding environment, Ling Yun did not feel any danger, so he felt relieved.

His figure flashed, only fifty meters away from the bronze giant gate, and sat cross-legged on the spot. Without any hesitation, he began to use the Qi Yin and Yang Technique and practiced wildly!

The colorful flames are released from the body, covering the 30-meter range of the whole body.

The vortex of the yin and yang true qi also overflows outside the body and is also controlled within the same range.

The two superimposed, turning into a huge vortex of flame, swallowing, tempering, and absorbing!

Whether it is dragon energy, emperor energy, or yin energy, once it enters this range, it will be immediately transformed into the purest yin and yang energy.

It's really too fast!

Lingyun's realm is rising steadily at an astonishing speed.

In less than an hour, Ling Yun successfully reached the peak of the ninth level of Qi training. In the sea of ​​consciousness in his eyebrows, the divine essence is full. In the qi sea and the dantian, the yin and yang energy have already transformed into liquid, just like the waves of the sea, surging and turbulent.

Ling Yun was unmoved and continued to practice until he felt that the foundation of a certain great way was brewing in his body, and he barely stopped.

It is only one layer of window paper to break through the foundation building realm.

Of course, Ling Yun could not build a foundation here, and the place and timing were not suitable.

What's more, he couldn't take out any of the important items used for foundation building, such as the five-color earth, the roots of Buzhou Mountain, a drop of blood from Gonggong, etc.

Lingyun stopped absorbing the outside world's breath and began to concentrate on stabilizing the state.

At the same time, Ling Yun sacrificed all the fighting magic weapons such as the Green Shadow Flying Sword, Yin-Yang Gang Qi Sword, Golden Dragon Spear, Human King Seal, etc., suspended them all around him, and constantly tempered them with colorful flames.

After the state is stable.

Ling Yun began to concentrate on practicing the Golden Emperor's Mad Dragon Slash.

There is no way, the dragon energy here is too violent and pure, and it would be a pity to miss it.

What if I can't come in once?

It didn't take long for Ling Yun to cultivate the Golden Emperor's Crazy Dragon Slash to the Great Perfection!

Ling Yun slowly opened his eyes, smiled and stopped, and stood up.

His eyes looked at the continuous palace at the end of the road again, regardless of whether there was anyone there, and he clasped his fists and said "Thank you".

"Can you open the door?"

Rumble...

The bronze giant door really opened again!

"Goodbye! When I finish my work, I will definitely come back to visit again."

Ling Yun clasped his fists again, left a sentence, and immediately flashed his body and flew out of the crack in the bronze door.

After Ling Yun left, the door immediately closed again.

Where Lingyun was, a white-robed general suddenly appeared.

"The skills are good, and the courage is good."

"It's just... it's too weak."
