Yang Feng and the others were shocked, caressing the bronze giant gate in front of them, and they could also see some traces of Ban Barge, and even the bronze giant door was carved with dense symbols, ancient and mysterious, and it was not clear its use and meaning.

"The entrance is here!"

With a shout of excitement, everyone's eyes turned to an entrance not far away, only to see that the rocks and dirt that had collapsed around them were mostly buried, but there was still an entrance exposed.

"Wang Lulu, Liang Yu, you go in with me."

Looking at the entrance not far away, Yang Feng immediately led Wang Lulu and Liang Yu in, and walked along the narrow passage towards the front, while the others also entered through the entrance.

"Look, the aisle ahead is much wider."

Luo Lang, the martial artist of the True Yuan Realm who took the lead in entering, found that the passage in front of him was much more spacious, his face was a little happy, and he walked quickly, and then everyone followed, and soon came to a relatively spacious place.

Here, it looks like a huge space, but many rocks have collapsed around it, and some huge pillars can be seen, as if it were an underground palace.

However, Yang Feng and the others did not take a closer look, but continued to move forward along the passage in front of them. Here, nothing useful exists, and only when you enter the interior does you know what is inside.

I don't know how long they walked, Yang Feng and the others only felt that the passage was getting wider and wider, and even in the end, they could see some dilapidated buildings on both sides, all buried in the mountain.

"It's here!"

Ahead, in front of a wide exit, a group of people were standing here in shock, staring blankly ahead. It's a shocking scene, and you're greeted by a huge city.

That's right, what Yang Feng saw was an incomparably huge city, which was an ancient city. From here, the interior of the city is neatly housed, but it has collapsed into ruins, and the ancient and desolate silhouette can still be faintly seen.

"Ancient city?"

True Yuan Realm martial artist Zhao Guang, his face was surprised, and he took three subordinates to look at everything in front of him in surprise, this is an ancient city, and several other True Yuan Realm martial artists also took their subordinates and looked at the ancient city in front of them.

"What now?"

True Yuan Realm martial artist Luo Lang glanced at Yang Feng and Zhao Guang, as well as several other True Yuan Realm martial artists, and asked softly.

Zhao Guang's eyes flickered, looking at the huge city in front of him, he couldn't see the edge at all, he could only vaguely see the outline, and there were many buildings in the ruins that had not completely collapsed.

This city is so huge that it is impossible to guess how big it is when a few people enter. At this time, everyone came here with a lively mind, and they must have thought of exploring each other.

"Let's each choose a direction and see our luck!" Zhao Guang directly dropped a sentence and left with two of his subordinates.

Other True Yuan Realm martial artists also left with their subordinates, and some lone True Qi Realm martial artists also scattered one after another to explore the ruins.

In the end, the remaining Yang Feng and the three of them were here, cautiously staring at the huge city in front of them. This ancient castle seems to have been built underground, but it is certain that it is not an underground castle.

However, to Yang Feng's confusion and surprise, there were no rocks falling from the sky above this city. In other words, the mountains above this city have not collapsed, which is the most amazing.

"Captain, what do we do now?" Wang Lulu asked.

"Let's go, let's go this way!" Yang Feng pondered for a while, and then said softly.

After speaking, Yang Feng directly chose a direction to walk, followed by Wang Lulu and Xia Hong.

Along the way, Yang Feng's face was surprised, looking at the collapsed buildings around him, he couldn't guess what kind of creature built the city was, and suspected that it was a prehistoric human?

"Look, Captain, this dust is strange."

At this time, Wang Lulu's face was very serious, staring at the thick layer of dust under the feet of the three people, which was grayish-white, and a lot of footprints could be clearly seen.

And Yang Feng checked it, his face suddenly turned cold, and his heart was extremely shocked, he found that these gray dust was not the dust of sediment, but the dust formed by bones.

"It's bone meal!"

The faces of the four of them were terrified, and when they stepped on it, they could faintly hear a crisp sound, as if they had stepped on something. Yang Feng flicked his feet and suddenly found that some broken bones were being exposed, and the color of Sensen was terrifying.

This is bone meal in one place, and there are broken bones, I can't imagine that there is such a thick dust here, three feet deep, is it all bone meal formed by the weathering of bones?

"A lot of bones, these seem to be human bones." Wang Lulu said cautiously after observing.

"The whole ancient city is too big, we may not be able to find anything by exploring like this, one person searches in one direction."

"If you encounter danger, send a signal, this place is too big, I will search each door to see if I find anything useful and collect all the things for me."

At this time, Yang Feng directly ordered the two of them, and then chose a direction with Wang Lulu, Liang Yu and others, and quickly explored in one direction.

Yang Feng separated from the two, and the figure rushed over quickly, carefully looking around along the way, hoping to find something.

It's a pity that Yang Feng was disappointed, and along the way, except for the thick bone meal on the ground and some broken bones, he didn't find any valuable things and clues.

Even, in the ruins of the rows of houses on both sides, nothing was found. The only thing worth noting is that some broken utensils can be seen from time to time in these ruins, but unfortunately they are incomplete.

Yang Feng even found that the wreckage of some weapons had been completely shattered and had lost their due luster. But what surprised him was that these fragments were still so hard and sharp, and he couldn't imagine how powerful these weapons were in their full life.

Bite!

In the ruins of a house, Yang Feng was holding a piece of debris to check, and with a flick of his finger, there was a crisp argument. His face was very amazed, and he looked at this small fragment, which was just a small piece of sharp metal, but it was still strong.

It's obviously very old, and I don't know how long it has been, the bones have turned to powder, and the fragments are still so sharp and strong, it's unbelievable.

"It's amazing"

Yang Feng's face was shocked, and he didn't hesitate, he collected these fragments one by one, estimating that he might be able to use them in the future, or when he had the opportunity in the future, he would reintegrate these metal fragments to forge a more powerful weapon.

Along the way, Yang Feng was carefully checking and was not in a hurry. He knew that since he had entered this ancient city, he had to be careful if he wanted to gain some benefits.

"The houses here seem to be made of rock, but what do these symbols mean and what do they do?"

At this time, Yang Feng came to a building that had collapsed more than half of it, and was looking at it curiously.

Because from the ruins in front of you, you can still see the complete wall, on which some ancient and mysterious symbols are depicted.

These symbols are mysterious, and they have an unknown function, not just for the sake of beauty. Yang Feng could only give up after looking at it for a long time, because he didn't know what these things were, what they meant and what they contained.

He walked quickly in the ruins, and carefully found that there were a few or most mysterious symbols on some buildings that had not collapsed and broken, and it was impossible to understand their intentions and functions.

However, Yang Feng suspected in his heart that these ancient and mysterious symbols must have a huge effect. It's just that he doesn't know the key to it yet, so he only vaguely perceives that it is important.

Even so, he didn't think much of it, and continued to walk forward, coming to a relatively spacious area.

From here, it looks like a square at first glance, but when you look closely, it's not right.

Yang Feng soon discovered that this was not a square, but a military camp.

That's right, if you look closely, you can clearly find that this is clearly a military camp, a place where army soldiers are stationed, or a place for rest and training.

"Barracks?"

Yang Feng's face was cautious, staring at a huge ruin in front of him, most of the buildings had collapsed, and some black tiles could be faintly seen scattered, not weathered cleanly.

And some huge pillars collapsed, leaving only a bare bottom, which can still prove the prosperity and prosperity of the year.

Yang Feng walked into the ruins, walking cautiously, without the slightest carelessness, he didn't know if there was a terrifying crisis inside this ancient city, but there was nothing wrong with being careful.

Kindness?

Suddenly, Yang Feng walked to a corner, but suddenly noticed that there was a powerful aura permeating him, and after careful distinction, he found that there should be a powerful True Yuan Realm martial artist in front of him.

As Yang Feng stepped forward cautiously and vigilantly, he found that in front of a huge building ruins, there were several burly figures standing here.

There are a total of four warriors, three of whom are one meter eight or nine tall, each holding a sharp bone spear in their hands, with a strong aura and a faint evil aura.

The most amazing thing is the first warrior, covered in solid bone armor, holding a huge skeletal white bone knife in his hand, sharp and terrifying.

This is a True Yuan Realm martial artist, more than two meters tall, and his whole body is oppressive, and he is extremely heavy. The strength of this True Yuan Realm martial artist is absolutely strong, stronger than most True Yuan Realm martial artists, and his aura faintly oppresses Yang Feng, stronger than Yang Feng.

"This True Yuan Realm martial artist is stronger than me, and he should be a True Yuan Realm Sevenfold Heaven martial artist!"

Yang Feng's face was cautious, and he felt that this True Yuan Realm martial artist was much stronger than him, this was an intuition, and the feeling for no reason was very profound. He firmly believed in his own feelings, which were instinctive feelings that arose after cultivating to a certain extent.
