The northern city of the capital garden.

Nangong Xuan came to the place where Fei Qingming told him alone.

Before sending Mu Shen and them back to Thunder Valley, he returned to the capital again.

He is also very interested in the spiritual vein, if this spiritual vein is taken away and brought back to the Thunder Valley, it will definitely benefit the Thunder Valley and will not harm it.

Originally, this place was heavily guarded by the academy before, but with the arrival of Nangong Xuan, those disciples have been transferred.

Nangong Xuan walked alone in this big mountain, and as soon as he entered it, he felt that the source qi here was extraordinarily rich compared to other places.

After confirming that there was indeed a spiritual vein here, Nangong Xuan was relieved.

It's just that the spiritual veins are hidden underground, and it's not easy to take them away.

However, this may be difficult for others, but for Nangong Xuan, it is a piece of cake.

Although his burial coffin could not be condensed, he could control the secret technique of burial abyss and temporarily receive the spiritual veins into the burial coffin.

Just do it, Nangong Xuan immediately ran the source qi to the extreme, and then cast the burial abyss.

Purple qi was pervasive, and under Nangong Xuan's control, it quickly enveloped the area.

Suddenly, the ground began to shake, and the people of Yuanbei City were terrified.

Fortunately, the academy had set up an energy barrier here before, and no one could explore it for a while.

It's just that the spiritual veins in this place are huge, and Nangong Xuan couldn't even receive them all into the burial coffin for a while.

Helplessly, Nangong Xuan could only adjust his state while casting the burial abyss to collect the spiritual veins.

A month has passed in a blink of an eye, and with Nangong Xuan's unremitting efforts, all the spiritual veins here have finally been included in the coffin of the burial abyss by Nangong Xuan.

However, before Nangong Xuan could be happy, suddenly a ray of light erupted from the earth, and then penetrated the barrier arranged by the academy.

This change has also attracted the attention of many people, and even Fei Qingming and others have noticed the movement here.

Nangong Xuan looked at this light with a stunned expression, and then shook the mountain again.

This time, a huge ruin unexpectedly broke through the ground and stood in front of Nangong Xuan.

Nangong Xuan wanted to enter and investigate, but he didn't want to be blocked, there was an invisible barrier here, so he couldn't enter it at all.

Nangong Xuan had no choice but to stay here, thinking that this invisible barrier would disappear soon, but he never thought that he would wait for three days.

In the past three days, news of the appearance of ruins here has spread far and wide, which has also led to the gathering of many cultivators here, and it is obvious that they are also coming for this ruins.

Fei Qingming and the others also rushed over.

"King Xuan, what's going on? How is there a ruin here? ”

Nangong Xuan smiled bitterly: "You ask me, who do I ask, I haven't figured out the situation."

"What about this ......"

Fei Qingming looked at the ruins in front of him and wanted to step forward, but found that there was an invisible barrier around him, and he couldn't get in at all.

He looked at the cultivators around him, and he wanted to drive them away.

Nangong Xuan saw Fei Qingming's intention and waved his hand.

"Since the ruins have already appeared, it is naturally obtained by the virtuous, don't pay attention to these people, and rely on their abilities after arriving at the ruins."

Fei Qingming nodded: "Okay."

Although he is still the dean of the academy, he knows his position very well, and since Nangong Xuandu has already said so, then he naturally can't say anything more.

Nangong Xuan suddenly frowned, and his consciousness fell into the coffin.

At this moment, there was a golden piece of gold in the burial coffin, and a whole spiritual vein filled the internal space of the burial coffin.

Let his golden pill be submerged, but this is not the main thing, he found that his golden pill was actually absorbing the energy of the spiritual vein.

But he didn't care.

In the blink of an eye, another day and a half passed, and more and more cultivators gathered here.

At noon, only a click was heard, and the invisible barrier that shrouded the ruins shattered, revealing the situation inside.

This turned out to be a huge mountain range, and the surrounding cultivators saw this and immediately rushed in.

Fei Qingming looked at Nangong Xuan: "King Xuan, let's?"

Nangong Xuan nodded: "Let's go, you don't have to follow me, go find an opportunity by yourself."

got Nangong Xuan's approval, Fei Qingming and the others were not polite, and they hugged Nangong Xuan, and they also entered the ruins.

Nangong Xuan walked into the ruins, only to feel that this place seemed to be very old, but he didn't know what was here.

Nangong Xuan took out the fragment of the holy card and shook the illusory old man out vigorously: "Old ghost, can you tell that this is from that era?"

The illusory old man shook his head: "I don't know, but it should belong to your civilized era."

Nangong Xuan pursed his lips and immediately put away the fragments of the holy card.

I thought this old thing knew everything, but it turned out to be nothing more than that.

Immediately raised his feet and walked into the depths.

It's just that what Nangong Xuan didn't notice was that somewhere, a pair of eyes were watching him.

"Sure enough, it's you, I didn't expect you to run to the Six Domains."

As he went deeper, Nangong Xuan discovered a cave that many cultivators had entered.

Nangong Xuan didn't think much about it, and also walked in.

As soon as I came in, I found that there was a cave here.

Although the entrance to the cave is not large, it is extremely wide inside.

Walking along the passage, Nangong Xuan soon came to the bottom, there were a lot of stalactites here, and at the same time, he also found that all the cultivators who came in before were here.

Obviously, the mountains are just a disguise, and the real inheritance is here.

It's just surprising that except for the steps, which are artificially formed, the rest are naturally formed.

What exactly is this place?

Nangong Xuan looked around curiously.

Then he went deeper, and soon he found that this place seemed to run through the whole mountain range, and he had been walking in it for almost an hour, and he had not even reached the end.

Just as he was wondering, a cry came.

"There's a dark pavilion here."

When everyone heard this, they immediately rushed to the place where the sound was made, and Nangong Xuan also walked over.

Sure enough, a secret room was carved out of this place, and various exercises and secret techniques were placed here.

When those cultivators saw this, their eyes immediately turned red, and they were crazy to snatch these exercises and secret techniques.

Seeing this, Nangong Xuan shook his head, and did not follow these people to participate, but continued to go deeper.

On the way, he encountered some secret pavilions, which not only contained exercises, secret techniques, but also pills, spirit stones and the like.

There are even various totems in it, but Nangong Xuan is not interested in this.

It wasn't long before he found himself in a secret room, where he found that it had been turned into a bedroom.

Looking at the interior layout, it is obvious that this is a woman's boudoir.

After turning around inside and finding nothing, Nangong Xuan planned to leave.

But when he hadn't taken a few steps, the floor under his feet was sunken.

Immediately afterward, the bed began to move, revealing a narrow passage.
