"Chang'an City?"

"Some secret?"

Su and Qin's thoughts turned quickly.

"Not bad."

Emperor Tang nodded slightly and said, "but I think it's fake. Although Chang'an city is big, if there's any secret, can you hide it for 500 years?"

The emperor of the Tang Dynasty took it for granted.

For more than 500 years, the outer city of Chang'an has been rebuilt many times. If there were any secrets, they would have been exposed.

As for the inner city, although it has always been the same as the imperial residence, there must always be a large army to patrol and guard it. In this case, there is no secret.

"I see."

Su Qin remained calm.

A moment later, the emperor returned to the palace of longevity.

After the emperor of Tang left, Su Qin got up slowly, took a step and disappeared in the same place.

At the same time.

Su Qin stands in the air, overlooking the whole city of Chang'an.

Whether it's the master of Luohan or the myth of Wulin, even if there is only one heavy sky, it can control Qi, ride the wind and go up freely.

What's more, Su Qin's five great consummation?

"The secret of Chang'an City?"

"I'd like to see what's the secret of Chang'an City?"

Su Qin's thoughts spread rapidly, and in an instant, the whole city of Chang'an was shrouded.

At this moment, all the actions of millions of people in Chang'an city fell into Su Qin's mind. It was like watching a pattern with the palm of his hand.

Although Su Qin had lived in the palace for so many years, he would visit Chang'an city every other time.

But it's the first time I've been as careful as I am now.

Hum!!!

The terrible idea spread to every corner of Chang'an city like flowing water.

"Yes?"

"No?"

Su Qin frowned.

The next moment.

Once again, the spirit condensed and began to spread slowly underground.

One hundred meters.

Two hundred meters.

Three hundred meters.

Five hundred meters.

One thousand meters.

...

at last, at 2500 meters underground of Chang'an City, Su Qin suddenly felt a strange breath.

"What's this?"

"Evil spirit?"

Su Qin's eyes narrowed slightly.

Su Qin has seen this kind of evil spirit in many places, such as the magic tower of Shaolin Temple, and the devil who killed Shaolin.

However, Su Qin never thought that he would find this evil spirit in the underground of Chang'an City, an ancient capital of ten dynasties.

Moreover, compared with the Zhenmo tower and the demon lord, the underground magic Qi is more pure. To be exact, although both are magic Qi, they are very different.

It's just like the true yuan of Luo Han and the internal power of nine grades.

"Interesting."

Su Qin continued to probe into the underground.

Finally, three thousand meters under the ground, Su Qin suddenly found a towering palace through his mind.

This towering palace occupies several miles, empty and uninhabited, but in the center stands a black wellhead.

And the wisps of evil Qi spread out from the black well.

Seeing this, Su Qin's figure disappeared again.

A moment later.

In front of the towering palace 3000 meters underground, Su Qin's figure appeared quietly.

"Such a deep underground, I'm afraid it's very difficult for a great master to come in..." Su Qin glanced at the towering palace and thought silently.

"The black well..."

after thinking for a moment, Su Qin walked towards the center of the palace.

He had already swept the palace inside and outside with his mind. Except for the black well in the center, other places were normal.

Soon.

Su Qin came to a stone tablet ten meters high.

There are many inscriptions on the stone tablet, which are all written in ancient Chinese characters for thousands of years, which is difficult to understand. However, it is difficult for Su Qin to understand. As early as in Shaolin Temple, he read the whole Sutra Pavilion, including the evolution of the characters.

"The magic well was born and connected with the underground world, and countless demons poured into the world..."

"the world was in chaos, but fortunately, the magic well could only accommodate the demons under the myth. After countless ancestors' bloody struggle, they finally sealed the magic well with the Dragon movement of the dynasty, blocking the passage between the underground world and the world..."

ancient words flashed by, which made Su Qin know the cause and effect Fruit.

According to the stone tablet, about thousands of years ago, or tens of thousands of years ago, a large number of demons suddenly appeared to bring disaster to the world.

And these demons are from this black magic well.

On the other side of the black devil's mouth is the underground world of demons, which is the real world of demons."It seems that the level of this underground world is very high, at least much higher than that of this continent..."

Su Qin touched his chin and thought deeply in his eyes.

According to the records on the stone tablet, thousands of years ago, that era should have been a period of great prosperity for martial arts. There are more than ten surviving martial arts myths.

But as a result, it was still directly maimed by the demons gushing from the magic well.

You know, the magic well can only accommodate the demons under the level of myth, that is to say, the Terrans were only facing a group of demons with the most strength at that time.

With at least ten myths, the human race is still in decline. It can be imagined how ferocious the world under the magic well is.

"No wonder Chang'an city is the ancient capital of ten dynasties. It turned out that only by taking Chang'an City as the center and gathering the Dragon transportation of the world's dynasties, can it be forced to seal the magic well..."

Su Qin thought silently.

At this moment, he probably figured out why the emperor Taizu of the Tang Dynasty wanted to establish the country. He was only worried about the loss of the dynasty, the suppression of Longyun, and the loosening of the seal. Finally, ten thousand demons entered the world.

"Keep looking."

Su Qin looked slowly at the stone tablet.

In addition to introducing the horror of Mojing, the records on the ancient stele tell us something about the world of the grottoes connected by Mojing.

Since the demons in the underground world can follow the magic well, the people above can naturally enter the underground world through the magic well.

During the period of fighting against the demons, many Wulin myths have sneaked into the underground grottoes. They are surprised to find that the world connected by the magic well, whether in scope or in high-level combat power, is far more than this continent.

And in the world of the devil's cave, the civilization similar to the human race has also developed. In the vast area, there are many powerful countries.

All the martial arts myths that have entered the underground world of the grottoes conclude that the existence time of the mushroom world of the Grottoes is at least 100000 years old, even far more than that.

After discovering this point, those Wulin myths who sneaked into the past were scared to death, so they quickly returned, and then sealed the magic well with the Dragon luck of the dynasty, completely cutting off the connection with the underground world.

What happened next is probably clear to Su Qin. The invasion of the demons directly maimed the martial arts in this continent. Even the martial arts myths fell down. The rest of the martial arts myths disappeared.

"Time?"

"At least 100000 years?"

Seeing this, Su Qin's eyes lit up directly.
