"The ground is emitting white air?" Fang Yu raised his eyebrows and looked at the ground under his feet.

"Well, they described it at the time... like steam rising from the ground." Zhao Jidao said.

Fang Yu stopped talking, his eyes were thinking.

There is a strange magic circle under the observatory, and white gas rises from the ground...

This kind of phenomenon is obviously abnormal.

But it doesn't make sense to say that the observatory was built to cover up anomalies on the ground.

Because the top of Qingyun Mountain is an inaccessible place.

The semi-spirits requested to build an observatory in a place like this, but they felt that there was no silver here.

Although the old man Daokong is not very smart, he is not that stupid either.

After thinking about it for a while, there was no result.

At this time, an idea flashed in Fang Yu's mind, and he thought of something.

A total of thirty-seven locations have been requested to build observatories. Could it be...

Fang Yu's eyes returned to normal, and he took out a map of the entire region from the storage space of the ethereal ring.

Based on the information given by Huaixu, Fang Yu marked all the thirty-seven locations where observatories were established on the map.

Then, connect the marked points with a line.

Soon, an extremely square pattern appeared in front of me.

Thirty-seven locations, connected exactly to form a square!

And all the internal locations are connected...

It's exactly the same as the underground formation that Fang Yu saw just now with his eyes of insight!

Fang Yu opened his eyes wide, opened his eyes of insight again, and looked at the ground under his feet.

Then, look at the connected signs on the map.

Exactly the same! Even the complicated connections inside are exactly the same!

This surprised even Fang Yu!

Underneath the ground at every location, there is likely to be the same magic circle.

In other words, when the small magic circles in each location are connected, they become a giant magic circle covering the entire Chinese region!

The function of this magic circle is not yet known.

But a magic circle with such a huge scope... As far as Fang Yu's knowledge is concerned, it has never appeared before since ancient times.

You must know that every setting of a magic circle must use a certain amount of spiritual energy as the energy to activate the magic circle.

A magic circle with such a huge coverage area may not be able to activate even if it drains all the spiritual energy from the world!

In fact, there is no way to drain away all the spiritual energy in the world.

"Unless... my understanding is completely wrong, this is not a magic circle at all. But if it is not a magic circle, what is it? Moreover, it does cover most of China." Fang Yu touched his chin and started thinking.

.

Zhao Jidao stood aside and watched Fang Yu thinking. Although he was full of doubts, he did not dare to disturb him.

…

Huaibei Nandu, northern villa area.

Behind the Zhao family's mansion is a hill.

On the top of the hill, there are only some small trees.

At this time, several black shadows suddenly appeared on the previously empty mountain top.

A black shadow three to four meters high was the first to appear.

It was the demon who had met Fang Yu in the ruins!

Immediately afterwards, four more figures appeared behind the demon.

The four men were dressed in gray robes and had a devil pattern on their foreheads.

"Lord Demon, the container... is in the house below." A man in gray robe said.

"Well, go down and take her away," the demon said.

The next second, the figures of the five people turned into black energy again and disappeared from the place.

…

"That's almost it. I have to rush to the next place." After thinking about it for a while, Fang Yu decided to go to the observatories in other areas to have a look.

"Uh... Master Fang, I wonder if you still remember my granddaughter Zhao Zinan?" Seeing that Fang Yu was about to leave, Zhao Jidao spoke quickly.

"Huh? What's wrong?" Fang Yu asked, raising his eyebrows slightly.

Of course he would never forget Zhao Zinan, a girl with a weird physique.

"She often mentioned to me that she wanted to meet you..." Zhao Jidao observed Fang Yu's reaction and said.

Fang Yu frowned slightly and said, "Next time, I'm a little busy now."

"I understand! I will tell her when I go back." Zhao Jidao said immediately.

"Um."

Fang Yu nodded, activated the ethereal ring, and prepared to leave.

At this time, Zhao Jidao's cell phone vibrated.

Zhao Jidao answered the phone and after listening to two sentences, his expression changed drastically.

"What!?" Zhao Jidao looked at Fang Yu who was about to leave and shouted, "Master Fang, please wait..."

Before he finished speaking, Fang Yu's figure disappeared in front of him.

Zhao Jidao's face was pale, and the hand holding the mobile phone was shaking violently.

As soon as he received the call, people from the Devil's Cult went directly to their home, killed more than a dozen guards, and wanted to capture Zhao Zinan.

If Fang Yu stays, things may turn around.

But now, Fang Yu is gone...

Just when Zhao Jidao was flustered and at a loss, another light suddenly lit up in front of him.

"What's wrong?" Fang Yu looked at Zhao Jidao in front of him and asked impatiently.

Zhao Jidao was stunned for a moment, and then he looked overjoyed and said, "Evil, people from the Devil's Sect have found our home, and they want to take Zinan away!"

"Devil sect?" Fang Yu raised his eyebrows, remembering the demon who escaped in the ruins.

…

Inside the gate of the Zhao family, there were more than a dozen mutilated bodies lying in miserable state of death. Most of the bodies were directly torn to pieces by brute force.

The smell of blood filled the air above the Zhao family.

At this time, in the hall.

"I will give you ten more seconds. If you don't hand Zhao Zinan over, every second, you will sacrifice one person." A man in gray robe stood in front of the demon and said.

The core members of the Zhao family were all kneeling on the floor of the hall, their faces bloodless and trembling.

Just seeing the appearance of the demon, their courage was shattered.

In this world, monsters like demons really exist!

"Ten, nine, eight..." The man in gray robe began to count down.

Many people present looked at the scene of the tragic death of the guards. They were so frightened that they were urinating and crying.

Zhao Xuan was also kneeling on the ground, his body trembling and his fists clenched.

A middle-aged man next to him reached out and pushed his shoulder.

Zhao Xuan glanced at this man and saw that it was his cousin, Zhao Shiqiao.

Zhao Shiqiao's eyes turned red and he trembled: "Xiao Xuan, I don't want to die, no one else wants to die!"

Hearing these words, Zhao Xuan's heart trembled.

Zhao Zinan was hidden by him.

He told Zhao Zinan not to go downstairs no matter what noise he heard.

But now, it's time for life and death.

The group of monsters in front of them are simply not something that ordinary warriors can contend with.

Even the guardians of the Martial Saint Realm were slapped into pieces by the huge demon...

If Zhao Zinan is not handed over... everyone present will inevitably die.
To be continued...
