Chu Chen didn't expect that this Jiaocheng was actually a dragon that had been dead for tens of thousands of years, and the entire body had become a fossil!

This dragon is about several hundred feet long, and the huge dragon mouth seems to be rising up to the sky and roaring, just forming a natural gate.

Behind the dragon's body that stretches hundreds of feet, there is a huge dragon's nest. The nest is a city transformed by ancient relics, and it is one of the largest and most crowded cities in the vicinity.

"If you want to enter Lei Jiao City, you need to pay a fairy crystal."

Just as Chu Chen walked into the huge Longkou city gate, two guards in black at the city gate stopped in front and said blankly.

The two black-clothed guards have a majestic aura, and the whole body is always exuding a bit of murderous intent to the surroundings.

This is the murderous intent that has truly experienced the great horror of life and death, honed in the **** battle, obviously in the small fairy world, in order to protect the city.

They have fought against the ancient beast countless times.

"This is the territory of the Thunder God Breaking Formation Group..."

Chu Chen glanced at the guards and found that there was a lightning totem outlined with silver threads on their chests. In the Little Immortal Realm, this was a unique symbol of the Thunder God Breaking Formation Group.

And this breaking formation group is also one of the top ten breaking formation groups of the Xeon in the Little Immortal Realm, with masters like clouds and strong.

Thunder Dragon City was originally an underground nest of Flood Dragons. It was precisely because of the presence of the Thunder God Breaking Group and their organization of personnel to transform the entire dragon nest, that it was built into a city suitable for monks to guard for a long time.

Therefore, although the cost of entering the city of this fairy crystal is high, it is also worth it.

After all, there is no need to worry about attacks by those ancient giants in this city. And there are many resources available within the city.

When Chu Chen left, Lu Yan once gave him a small bag of fairy crystals, but this time it worked.

After surrendering a fairy crystal, he stepped into Thunder Jiao City and took a breath.

How magnificent is the city transformed by Jiaolong's underground nest?

A monk who hadn't seen it in person would never imagine it.

Stepping into the ancient city is as if you have come to an underground kingdom.

At a glance, huge karst caves criss-cross, spreading over thousands of acres.

Each cave is like an independent space, many more clean water sources, air chambers, and warm houses.

There is a connected place between the cave and the cave. Those connected boulders have been cleverly cut into stone temples, as shown by the spar map at the entrance of the city. Every stone temple in the city is crowded with people, very lively.

Since the entire dragon’s nest is underground, there is not enough light, but almost every cave is surrounded by several fist-sized night pearls. The soft light shines on the entire city like the legendary city that never sleeps. Incomparably brilliant!

"It's so handsome!"

Chu Chen, who had just entered the entrance of the city, sighed slightly.

It can be seen that those caves should actually be the time when the ancient flood dragons survived. The shuttle was opened and formed, and the long passage was just able to accommodate the shuttle dragon's body.

The complex connection of the stone temple and cavity between the karst caves was made by the dragons after they were opened up, and they have undergone a lot of transformations to make them suitable for monks to live.

Unlike other cities, every cave here is like a bustling street.

After all, compared to the flood dragon, which is often dozens of hundreds of feet long, the human body is really too small. Therefore, it is not a simple matter to transform such caves.

From this aspect alone, the fee for entering the city of the fairy crystal charged by the Thunder God's Breaking Formation Group is indeed worth it.

Watched for a while at the entrance of the city. Only when Chu Chen officially entered Thunder Jiao City did he really enter the huge caves and discovered that there was a lightning-shaped stone monument at the entrance of each cave, with road signs and text instructions engraved on it, marking the trading caves and tasks. Caves, recruitment caves, supply caves, etc.

There are even several caves with very conspicuous bright red lightning marks marking the dangerous area. The dangerous cave closest to the entrance is said to contain the resentment devil after the death of the ancient dragon. This entrance is completely sealed by the overlapping seal formations. dead.

This cave caused Chu Chen's interest. Because his spiritual sense detected a trace of pure dragon energy in the depths of the cave!

It's the real dragon spirit!

Perhaps because of the nourishment of years of resentment, that trace of dragon energy has also been polluted. But if it can be captured and refined, that trace of dragon energy is definitely a rare treasure!

But at this time, on the one hand, this place was sealed by the Thunder God Breaking Formation Group, presumably that trace of dragon energy is already a masterpiece, he is not good at secretly planning any more, and after a while, he will directly move towards his destination. Recruit the cave and go.

In a large-scale relic city such as Thunder Jiao City, there are basically special recruitment locations that are used to recruit new people and replenish new blood for those powerful formation-breaking groups.

Exploring the ancient ruins has never been a simple matter. Casualties often occur. Even the most powerful group of Extinguishing Immortals and Breaking the Formation will be sacrificed every time the formation is broken. This kind of thing is simply unavoidable.

Although from the entrance of the city, the whole city looks like one after another, and it feels that there are many people, but when you really enter the city, the population density you see is not as large as you imagined.

Along the way, there are not too many people in even the most prosperous trading cave, which is a strange visual difference.

Perhaps because the caves are too big, the height of each cave is more than ten feet tall.

The huge underground city formed by countless karst caves is unimaginable. A monk living in such a city is like an ant living in a human house. It looks very empty and even feels deserted.

After walking into the recruitment cave, Chu Chen was surprised to find that there were actually more people here than the trading cave. There were about thousands of people in the bustling cave, divided into more than twenty strongholds.

There are a lot of people around the more famous Recruitment strongholds, and the crowd is almost crowded wanting to join in.

In contrast, those less well-known groups are almost Menkeluoque, very deserted.

Looking around ~lightnovelpub.net~Chu Chen quickly discovered the recruitment stronghold of the Miexian Breaking Formation Group, and immediately walked over.

There were very few people stationed in this stronghold, only one man in white who appeared to be about twenty-five or sixteen years old.

When Chu Chen came, this person was packing things up, and he seemed to be going back.

"Senior brother, do you still recruit people for the Destroying Formation Mission?"

Chu Chen's voice was a bit agitated. After coming to Little Immortal Realm, she finally saw the team of Little Junior Sister.

In terms of his own strength and background, no matter how harsh the conditions for joining the group, he is confident that he can meet their requirements!

"It's full, it's full, go back."

The white-clothed man's voice was a little impatient. When he said these words, he was putting jade charms into the storage ring, and he didn't even lift his head.
