Hanging on a mountain, inside a dimly lit cave.

A figure in a black cloak, standing in front of a rock wall, holding a broken white skeleton in both hands, is making something.

Just as he was concentrating on the production, a blurred mouth suddenly appeared on the rock wall in front of him.

"Soul Stream, I need to report something. The mouth on the rock wall moved, making a dull sound.

"Say it. Soul Flow didn't stop what he was doing, and said.

"As you requested, I triggered a battle between Tianchen and Fang Changsheng...... It's a pity that the contradiction didn't escalate as expected, Tianchen just summoned the will of the law to fight Fang Changsheng......" said the mouth on the rock wall.

"What was the result?" Soul Flow asked, raising his eyes, his amber eyes glowing with a faint light.

"Tianchen's will of the law used the Tianluo sealing technique, which was easily broken by Fang Changsheng, and the will of the law was also shattered...... Tianchen threw in the towel. ”

"Admit defeat......" Soul Flow's eyes flashed with a different color.

Tianchen admitted defeat in public, he thought that Fang Changsheng's strength was far superior to him...... Therefore, he would rather make a fool of himself in front of everyone than continue to fight with Fang Yu. ”

"In this way, we overestimate Tianchen's strength...... What do you think of Tianchen's injuries right now?" Soul Flow asked again.

"The will of the law has been shattered, and it will take at least two to three months to recover. During this period, his strength will be reduced by three to four percent. "The mouth on the rock wall kept moving, making a constant sound.

"Three to four percent...... Do you have faith?" Soulflow asked.

"I ...... I'm not sure, but if you can provide some help, then I'm 100% sure. ”

Soul Stream's eyes flickered, the movement in his hand stopped, and he said, "I will let Jiukong go to help you, but you must make the most perfect plan." ”

"Lord Nine Skies...... Okay! I see, Soul-sama!" the voice from the mouth on the rock wall became agitated.

......

Fang Yu left the Yangxin Temple and returned to the Northern Capital One Hundred and One.

Before setting out to deal with the Half-Ellings, he needs to eat a big meal and then get some sleep to get rid of his sleepiness and hunger.

During dinner, Ye Shengxue glanced at Fang Yu and asked, "Mr. Fang, are you leaving early tomorrow morning?"

"yes. Fang Yu replied with his head bored.

"How long are you going to be away this time?" Ye Shengxue asked.

"I don't know the exact time, maybe a week, maybe a month, or even longer. Fang Yu said.

"Oh. Ye Shengxue wanted to ask if she could go with her, but she quickly realized that if she followed, it would only become a burden, so she didn't speak.

"Master, don't you go for hundreds of years...... I don't care, but Sister Shengxue is different, can you bear to watch her wait here until she is old?"

Fang Yu glanced at the little wind chime and said, "After eating, bring me a few magic weapons......

......

At eight o'clock the next day, Fang Yu located the southern capital of Huaibei and teleported away alone.

In addition to looking for the lair of the half-spirit clan, he also had a purpose on this trip, which was to understand the so-called torrent.

He wanted to know what was going on in the world today, on a level that he couldn't see.

Soon, Fang Yu's figure appeared in front of the gate of the Huaibei Martial Arts Association Hall.

took out the pass order given to him by Huaixu, and without encountering the slightest obstruction, Fang Yu came to the president's office and met Zhao Jidao.

Seeing Fang Yu, Zhao Jidao immediately got up, stepped forward, and asked respectfully, "Lord Fang, ...... you?"

"Some time ago, did you receive an order from the upper echelons to establish the so-called observatory?" Fang Yu asked.

“...... Yes, Lord Fang, do you want to ......" Zhao Jidao looked at Fang Yu suspiciously.

"Has it already been built?" Fang Yu raised his eyebrows and asked.

"This was an order that was given three months ago, and we built it two months ago. Zhao Jidao replied.

"Take me to the observatory. Fang Yu said.

......

Yesterday afternoon, Fang Yu got a document in Huaixu's hand.

This document records in detail every martial arts association that Pan Yushan and Luo Hao demanded the establishment of the observatory during their control.

In fact, there are quite a few martial arts associations that have been asked to establish an observatory, and there are 37 in total.

Among the thirty-seven martial arts associations, the ranks are different. At a high level, there are third-level martial arts associations in large regions, such as the Huaibei Martial Arts Association. And the low-level ones also have a fifth-level martial arts association in a small county town that is not well known in a certain area.

From here, it can be seen that the conditions for the establishment of the observatory have nothing to do with the rank of the martial arts association, but only with its location.

If you want to investigate the demi-spirits, there is no other way to do it, so you can only start here.

......

Half an hour later, Fang Yu followed Zhao Jidao and came to the famous Qingyun Mountain.

The height of this mountain is about 500 meters, which is not very high, but it is located in the Nandu Forest Park, so it is very famous.

"The Beidu side gave us precise coordinates, which happened to be located in Qingyun Mountain, and they asked us to build an observatory on the top of Qingyun Mountain. Zhao Jidao smiled wryly and said, "This place belongs to the scenic spot, and we were allowed to build an observatory on the top of the mountain for a long time after we had a long time with the person in charge of the forest park. ”

"But Qingyun Mountain is not high at all, to be honest, it is surrounded by other high mountains...... It is simply not reasonable to establish an observatory in such a place. ”

"However, after all, it is an order from the Northern Capital, although we are confused, we can only do it. ”

Fang Yu and Zhao Jidao flew with the imperial qi and soon came to the top of Qingyun Mountain.

Here, sure enough, an observatory was built.

It is said to be an observatory, but it is actually a wooden platform with an astronomical telescope and astronomical tools in the corona.

"What exactly does the observatory need, didn't they ask for it?" Fang Yu asked.

"No, in fact, observing astronomy has nothing to do with our Martial Arts Association...... So at these observatories, we also randomly placed some astronomical tools on them. After Zhao Jidao finished speaking, he glanced at Fang Yu, a little afraid.

After all, Fang Yu was holding the top pass in his hand.

Therefore, he believed that Fang Yu had come this time to inspect the relevant facilities on behalf of the Northern Capital Martial Arts Association.

And in front of Fang Yu, he didn't dare to lie, he could only tell the truth.

Fang Yu ignored Zhao Jidao's careful thoughts, walked to the observatory, and looked around through the astronomical telescope.

But the result is just like what Zhao Jidao said, this location is not a good location for observing astronomy, and it is blocked by higher peaks on all sides.

"They didn't ask for the specific facilities of the observatory...... In other words, the role of the observatory is not really to observe astronomy. Fang Yu thought to himself.

But if it is not used to observe astronomy, why do you need to establish an observatory?

Fang Yu thought for a moment, released his divine sense, and searched the entire mountaintop.

Overall, there is nothing out of the ordinary.

Fang Yu's brows tightened, he thought about it, and opened his eye of insight again.

Now, he finally saw something strange.

In the field of vision of the Eye of Insight, where the observatory was located, about a meter below the ground, a magic circle with a general frame of squares and countless lines interlaced in it!

The entire magic circle was glowing with an extremely faint light, and it did not exude a trace of strange aura.

Without the Eye of Insight, it would not have been discovered.

"What is the magic circle down here for?" Fang Yu narrowed his vision and observed carefully, but he didn't have a clue.

The entire structure of the magic circle was quite complicated, and the theory of the magic circle related to Fang Yu's previous study did not seem to be the same system.

Even the approximate purpose of this circle cannot be seen.

"These circles should have existed before. The Demiling Clan had given the exact location and asked to build an observatory, was it to make a mark, or to cover up the special features of the original ground?" Fang Yu thought to himself.

"When you were building the observatory, did you find anything strange about this place?" Fang Yu looked at Zhao Jidao on the side and asked.

Zhao Jidao frowned at the meeting, and after a while, his face changed, and he replied, "It's really ...... It's just that I didn't seem to care too much about being controlled at the time. ”

"When the team in charge of building the observatory found this place, they reported that the ground where the observatory was built on the top of the mountain actually emitted wisps of white gas......
