On the memorial tablet, three ancient fonts are written.

"Xia Chunyuan!"

At this moment, Mu Yun blurted out.

Muyun doesn't know who Xia Chunyuan is.

But here, it can be judged that it is really not a palace for people to live in.

This palace seems to be dedicated to the dead figures of the Xia family.

"Similar to ancestral temple..."

Mu Yun whispered, "but if you want to worship your ancestors, set up ancestral halls. Is it necessary to build underground palaces and place memorial tablets in the underground palaces..."

Xiao Yuner also nodded.

They left the underground palace and then checked several underground palaces. In the center of each underground palace, there was a memorial tablet.

Even looking, they are all Xia people.

At this moment, Mu Yun rubbed his eyebrows and said, "it seems that this is really the same place as Xia family ancestral temple..."

It's just, it's still that problem.

Ancestral halls are ancestral halls. How lively are you staying together for generations?

Now one underground palace for one person is deserted.

Unless... There's something special in doing so.

At the moment, Mu Yun looked around with a calm look in his eyes.

What could it be?

At least it was the Xia family that was comparable to the first-class forces in the past. Even after a lapse of more than 100 million years, many things were not well preserved, but they were always of great benefit.

Mu Yun and Xiao Yuner went to check underground palaces one by one with doubts.

At the moment, Tuoba Xiu, Nangong Lingyue and Li pin are also among hundreds of underground palaces to check carefully.

At this time, Mu Yun and Xiao Yuner came to an underground palace.

This underground palace is taller.

In the underground palace, there is still a plaque in the center.

"Xia Qingying!"

Mu Yun looked at the three ancient characters on the plaque and found nothing else. He was ready to leave.

But when he turned around, Muyun stopped.

no

incorrect.

What's different!

Although he couldn't say, he felt something different just now.

This underground palace hall is different from the other underground palaces he and Xiao Yuner saw just now.

Mu Yun now forced himself to calm down.

"What's going on?"

At this time, Xiao Yuner also found that Muyun was wrong and looked around carefully.

In the end, xiaoyuner looked at the memorial tablet and said, "this memorial tablet is different from the previous one..."

"What's different?"

Mu Yun immediately said.

"This memorial tablet looks... Brighter..."

Yes!

At the moment, Mu Yun's eyes suddenly brightened.

There is no problem with the handwriting of the memorial tablet. The problem is the memorial tablet itself.

Brighter!

Mu Yunzi looked at the memorial tablet carefully and said, "it should be more than the ancestral temple worship. Maybe these dead Xia family elders will leave something for future generations..."

Mu Yun looked at the memorial tablet, and the Taoist boundary lines condensed, looking at the memorial tablet every minute.

After a long time, suddenly, the light flickered in the memorial tablet.

At this moment, the wall behind the memorial tablet makes a buzzing sound at this moment, spreading towards both sides.

At the moment, Xiao Yuner's beautiful eyes had an incredible expression.

Mu Yun was careful and came behind the wall.

Behind the wall is a room with three sides, and the bookcase is close to the wall.

The bookcase is lattice by lattice, with books and some exquisite glass bottles

Look carefully, those glass bottles are bright and have a somewhat exciting breath.

Muyun and Xiao Yuner looked carefully.

On the bookshelf, there are bamboo slips, scrolls and yellowish books.

When you open the bamboo slips and scrolls, you can see some martial arts and some understanding of practice.

After observing for a while, Mu Yun said, "it seems that he was a martial artist in the early days of melting heaven."

"The left scroll describes the cultivation and understanding, mostly related to the martial arts of Tongtian territory and how to break through the Rongtian territory..."

Xiao Yuner opened the glass bottles and said, "there are seven grade elixirs in them. They can help those who melt the heaven and pass through the heaven to recover their injuries and practice..."

Although it is not very precious, Muyun is also very satisfied.

In this way, the underground palace is not ordinary.

When the older generation of Xia family martial artists are about to sit down, they will leave everything here to leave to their predestined offspring to get and improve themselves.

It's a gift to future generations.

The underground palaces in front are empty. It should be that things have been taken away by the descendants of the Xia family.

However, not all the things in it are completely taken away, and the Xia family will perish

It seems that there are still some here.

Mu Yun immediately put away those scrolls, books and pills.

In fact, Muyun didn't pay much attention to the pill. Instead, these scrolls and books recorded the path of practice through heaven. His experience was very important to him.

After a sweep, the room looked rather empty.

"What is this..."

At the moment, Mu Yun squatted down and found a wooden box in the corner of the room. It looked dull and plain.

After opening the wooden box, I only saw a total of ten slots inside. However, one of the slots was empty, and there were only nine slots, containing nine incantation balls that looked to be branded with cyan patterns on the surface.

On the open side of the wooden box, a line of small characters recorded the information of the green ball.

"Thunderbolt xuanlei!"

Mu Yun whispered, "it contains the power of God thunder. It is forbidden here. It can be compared with the full attack at the peak of tongtianjing."

Good stuff.

As soon as Mu Yun's eyes brightened, he immediately put away nine thunderbolts and xuanlei.

With these nine guys, you don't have to panic even in the face of Tongtian's six, seven and eight opponents.

Mu Yun put away the thunderbolt xuanlei and looked around. After confirming that there was no omission, he left with Xiao Yuner.

After leaving the room, the memorial tablets were placed and the walls were closed. Everything looked as calm as when Mu Yun and Xiao Yuner first entered here.

At the moment, Mu Yun smiled and said, "it seems that there must be at least dozens of such palaces in these hundreds of underground palaces? We can get a lot..."

Xiao Yuner also nodded slightly at the moment.

They left the palace and then entered other underground palaces. One by one, they began to investigate.

During this period, every palace was in general shape, and Mu Yun and Xiao Yuner did find several.

However, most of them are scrolls and ancient books. There are almost no eight grade boundary tools, boundary pills, nine grade boundary tools and boundary pills

It's reasonable to think about it.

It's hard to say here that after the death of those strong Xia family members, they left behind some spiritual heritage, such as elixirs and weapons. It's just that they are too high-level, and the Xia family is not willing to dust here.

It may also be that the Xia family is about to perish. Someone took away many things here, and the rest is only those that are slightly useful to the martial arts in Tongtian territory.

However, after checking dozens of underground palaces, Muyun was satisfied with the harvest.

It is related to the practice of connecting heaven and the refinement of dominating Tao. Those recorded in scrolls and bamboo slips do not exist in today's era. While Mu Yun and Xiao Yuner were staying in a main hall, there was a deafening roar outside
