On the hanging mountain, inside a dim cave.

The figure in the black cloak stood in front of the rock wall, holding a broken white bone in both hands, and was making something.

While he was working on the production intently, a virtual mouth suddenly appeared on the rock wall in front of him.

"Master Soul Liu, I need to report something." The mouth on the rock wall moved, making a dull voice.

"Let's talk about it." Soul Liu said without stopping his hand.

"According to your request, I triggered the battle between Tianchen and Fang Changsheng...Unfortunately, the contradiction did not escalate as expected. Tianchen just summoned the will to fight with Fang Changsheng..." said the mouth on the rock wall.

"What's the result?" Soul Liu raised his eyes, his amber pupils glowed faintly, and asked.

"Tianchen's will of law used Tianluo's seal technique, and it was easily broken by Fang Changsheng, and the will of law was also destroyed...Tianchen gave in."

"Acknowledge..." A different color flashed in Soul Liu's eyes.

"Tianchen admits defeat in public. He thinks Fang Changsheng's strength is far superior to him... so he would rather make a fool of yourself in front of everyone than continue to fight with Fang Yu."

"In this way, we have overestimated Tianchen's strength... Do you think, how is Tianchen injured now?" Soul Liu asked again.

"The Will of Dharma was shattered and it took at least two to three months to recover. During this period, his strength would be reduced by 30 to 40%." The mouth on the rock wall kept moving and continued to make a sound. .

"Thirty to 40%...Do you have confidence?" Kunliu asked.

"I...I'm not sure, but if you can provide a certain amount of assistance, Master Soul, then I'm sure of it."

Kun Liu's eyes flashed, and the movement in his hand stopped, and said: "I will let Jiu Kong go to help you, but you must make the most perfect plan."

"Master Jiukong...Okay! I see, Master Soul!" The voice from the mouth on the rock wall became excited.

...

Fang Yu left Yangxin Temple and returned to Beidu No. 101.

Before setting off to solve the semi-spirit race, he needs to eat a big meal first, and then sleep again to eliminate 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, sullenly eating.

"How long are you leaving this time?" Ye Shengxue asked.

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

"Oh." Ye Shengxue wanted to ask if she could follow along, but she quickly realized that she would only be a burden if she followed, so she didn't speak.

"Master, don't leave for hundreds of years...I don't care, but Sister Shengxue is different. Do you have the heart to watch her wait here until the youngest child?" Across the table, Xiao Feng Chime raised her head and said .

Fang Yu glanced at Xiao Feng Chime and said, "After eating, bring me some magical artifacts..."

...

At 8 o'clock the next day, Fang Yu located the southern capital of Huaibei and teleported away alone.

In addition to finding the lair of the half-spirit race, he also had another purpose in this trip, which was to understand the so-called torrent.

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

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

He took out the passage order Huaixu gave him, and Fang Yu went to the president's office without encountering any obstacles, and saw Zhao Jidao.

Seeing Fang Yu, Zhao Jidao immediately got up, greeted him, and asked respectfully: "Master Fang, you..."

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

"...Yes! Master Fang, you want..." Zhao Jidao looked at Fang Yu suspiciously.

"Has it been completed?" Fang Yu asked with a frown.

"This is an order issued three months ago, and we have completed it two months ago." Zhao Ji replied.

"Take me to the observatory to take a look." Fang Yu said.

...

Yesterday afternoon, Fang Yu got a piece of information in Huaixu's hands.

This information records in detail every martial arts association that requested the establishment of the observatory during the period when Pan Yushan and Luo Hao were under control.

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

Among the 37 martial arts associations, the levels are different. There are three-level martial arts associations in large areas, such as the Huaibei Budo Association. And for the low-level, there is also a fifth-level martial arts association in a small county town in a certain area.

It can be seen from this that the conditions for the establishment of the observatory have nothing to do with the level of the Budo Association, but only with its location.

If you want to investigate the semi-spirit race, there is no other means, you can only start from here.

...

Half an hour later, Fang Yu followed Zhao Jidao 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 on Qingyun Mountain. They asked us to build an observatory on the top of Qingyun Mountain." Zhao Jidao smiled bitterly and said, "This place belongs to a scenic spot. The responsible party wrangled for a long time before being allowed to build an observatory on the top of the mountain."

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

"However, after all, it was the order from the Northern Capital. Although we were puzzled, we could only follow it."

Fang Yu and Zhao Ji flew imperially, and soon came to the top of Qingyun Mountain.

Here, indeed, an observatory was built.

Said it is an observatory, it is actually a wooden high platform with an astronomical telescope and astronomical tools in the corona.

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

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

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

Therefore, he believes that Fang Yu came here to inspect related facilities on behalf of the Northern Capital Budo Association.

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

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

But the result is the same as Zhao Jidao said, this location is not a good location for astronomical observation, all sides are blocked by higher peaks.

"They didn't ask for the specific facilities of the observatory...that is to say The role of the observatory is not actually used to observe astronomy." Fang Yu thought.

But it is not used to observe astronomy, why is it required to establish an observatory?

Fang Yu thought for a while, released his spiritual consciousness, and searched the entire top of the mountain.

Overall, there is nothing unusual.

Fang Yu frowned, thought about it, and opened his eyes of insight again.

Now, he finally saw a strange place.

In the vision of the Eye of Insight, at the location of the observatory, about one meter below the ground, there appeared a square frame with countless lines intertwined!

The entire array was glowing with a very faint light, without a trace of strange aura.

If there is no eye of insight, it is impossible to be discovered.

"What is the magic circle below this for?" Fang Yu zoomed in and observed carefully, but he didn't have a clue.

The structure of the entire circle is quite complicated, and the circle theories related to Fang Yu's previous studies do not seem to be the same system.

Even the general purpose of this magic circle cannot be seen.

"These magic arrays should have existed before. The semi-spirit tribe has given accurate positioning requirements to build an observatory. Is it to mark or cover up the original special features on the ground?" Fang Yu thought.

"When you were building the observatory, did you find this place strange?" Fang Yu looked at Zhao Ji and asked.

Zhao Jidao frowned at the meeting. After a while, his expression changed, and he replied, "It's true...but I was under control at the time. I didn't seem to care."

"When the team responsible for building the observatory found this place, they reported a message. He said that on the ground where the observatory was built on the top of the mountain, there would be wisps of white gas..."
