Sure enough, after pressing it, some information was displayed.

It's just that Yuanyun's name really can't be displayed no matter what.

Because at this time, the name on the booklet only shows a cloud character, and the first word in front of it is not clear no matter what.

The guards were puzzled when they saw this.

In the end, after letting Yuanyun press it a few times, the result was still the same.

However, this booklet is classified and does not infringe on the privacy of others.

Just reveal some basic information, such as height, looks, and so on.

After Yuanyun tried a few more times, the guards directly asked Yuanyun to report his name.

After all, if you press it again, it will be the same result, and it will make this Taoist friend bored at the same time.

Immediately, the guard gave Yuan Yun a red rock crystal.

Yuan Yun looked at this crystal and immediately knew what it was. This was unexpected, but he didn't expect that after registration, red rock crystals against the scorching heat would also be distributed.

This was unexpected.

I didn't expect to register and send crystals, which made Yuanyun exempt from buying crystals.

Although it is cheap, Yuanyun is troublesome, so it is better not to run errands for this.

At this point, one man and one beast embarked on the journey again.

After a few days of man-man and beast, they finally arrived at their destination.

The Fallen City

The city of the fallen sits in a valley, but this city is suspended in mid-air.

Beneath the valley here is a gently flowing river.

But this river is not an ordinary river, because what is in this river is not ordinary clear water, but hot molten lava.

The city is even more strange, usually on a lava floor, while the other half is full of vibrant green mountains and green waters.

Moreover, the division of the two environments is very clear, and it is directly divided into two parts by a river.

Of course, this river is exactly the same as the one in the valley, and it is all hot lava.

The river channel suspended above the valley directly converges into two lava waterfalls that fall into the lava channel of the valley.

This is also a rare wonder in the world.

After all, waterfalls are common, but they are all waterfalls.

It's rare to see such a molten slurry coming together.

The Old City is magnificent, because it is more than a thousand feet high in his main city, and there are at least dozens of floors underground.

As for the people who live in these main cities, they are divided according to rank.

The worst people live on the top floor, and the bottom people are the highest in between.

As for why the person with the highest rank didn't live on the top floor, Yuanyun didn't know much about it.

The city is already magnificent, and the pale red transparent barrier around it adds a different color.

At this time, the periphery of the old city was full of scattered mounts and birds.

But there was nothing in the air inside the city, and it seemed that no spirit beast had ever been able to fly into it.

"Momo, can you fly higher? A little higher. This old city is indeed a bit tall.

You're not taller, let me observe. ”

The beast seemed to have a bad sense of hearing. The whole book

Completely ignoring what Yuan Yun said, it was as if Yuan Yun hadn't heard a word of what Yuan Yun said.

Yuan Yun had no choice but to pat the back of the Hongqu Hua Saucer Beast vigorously, and then said loudly again

"Momo, fly a little higher, higher, a little more."

This time, the Hongqu Hua Saucer Beast finally heard Yuanyun's words, and then it had to be high.

It's just that it seems that in the end, this old city is higher, and the red beast has been abandoned for a long time, and it has not flown to the top of the old city.

In addition, in the past few days, the Hongquhua Saucer Beast has also been flying day and night, and fatigue is indispensable.

Simply Yuanyun also sensed the fatigue of the Hongquhua Saucer.

So, Yuanyun ordered Momo not to fly high anymore.

Only then did Yuanyun see that this fallen city was like a Luban lock, but there were indeed some differences.

Because Yuanyun had just observed, the top of the Falling City was indeed exactly the same as the upper part of the Luban lock.

But the bottom of the fallen city is not at all like the appearance of Luban lock, but like a quadrangular pyramid.

In a short time, Yuanyun discovered the only entrance to the Fallen City through observation.

Lava channels.

It's just that there is someone to guard it, and the only thing next to it is a merchant.

This merchant sells crystal, but this crystal is not like red rock crystal, but has a stronger color than red rock crystal.

It's blood-red.

Blood-red?

Yuan Yunwu thought of something, it was a lava crystal!

At this time, the best crystal in the Chiliu country is also the most precious and rare crystal.

Not only because its ability to resist the heat is top-notch, but also because of the wide range of functions of these crystals, which makes people have a mysterious pursuit and yearning for them.

Because this crystal is not only used for refining weapons, but also can be used to refine elixir under special extraction methods. At the same time, it can also use spiritual power to refine the scorching qi in its body, and then it can be absorbed to increase the spiritual power in its body, which is a smoother and faster path to cultivation.

Therefore, this lava crystal can be sold for a very high price not only in the Red Stream Country, but also in other countries.

Yuanyun didn't expect that this fallen city would have such a precious treasure.

"Let's go, Momo."

The Hongqu Hua Saucer Beast quickly fell to the ground with the abyssal clouds.

Yuanyun also began to line up with the people in the underground.

It's just that the queue is too long, so this also makes Yuanyun feel like a waste of time.

It took a long time, but at this time, two people in front of him actually fought.

"Just because you're embarrassed to beat Lao Tzu? Do you know who Lao Tzu is? It's really TMD that you can't see dog things for a long time, hurry up and get out, otherwise you will have no return.

Really, the city is not a place where a junk like you can come whenever you want.

What a waste of Lao Tzu's time and energy.

Bah. ”

Yuan Yun observed for a long time, only to realize that this middle-aged man who was scolding was one of the examiners who entered the Old City.

In addition to this examiner, there are five examiners, all of whom are there to test the abilities of those who enter the Old City.

In fact, this kind of rule seems to be the law of the jungle, but in fact it is actually a hidden protection rule.

This rule selects those who can barely survive in the fallen city, and those who are too weak are disqualified from entering the fallen city.

While it may be cruel to them, nothing is more horrible than death.
