Fang Yu suddenly thought of a magic weapon.
When he was on earth, he had a magic weapon called Dayan Lantern.
That artifact can pass through the subtle breath to trace the source of the breath.
Once, Fang Yu used this magic weapon to find immortal creatures.
However, Fang Yu did not bring this magical artifact to Datianchenxing.
It's just that the previous searches of the treasure pavilions of the various sects in succession have allowed him to obtain a lot of valuable artifacts.
One of them, similar to the Dayan Lantern, was stored in the storage space by Fang Yu.
"bass!"
Fang Yu took out this magical artifact.
This is not a lamp, but a bronze compass!
This compass looks extremely old, with many broken scratches on it, and the whole is bleak, it doesn't look like a very good magic weapon.
But the function of this compass... is not inferior to Dayan.
It can even be said that its function is stronger than Dayan lamp!
'Tian Yin'.
This is a fuzzy character engraved on the back of the compass.
Therefore, the name of this compass is Tianyin Compass.
Fang Yu held the compass in his hand and walked into the inner courtyard of Cao's family.
Huaixu happened to be in the yard.
"Brother Fang, you are..." Huaixu saw the compass in Fang Yu's hand with a look of doubt on his face.
"This is a powerful magic weapon, but I don't remember which sect I got it from." Fang Yu said.
Approaching the ashes on the ground, Fang Yu knelt down.
When he and Huaixu came to the Cao's mansion for the first time, they smelled the smell of burning and blood remaining in the air.
And this smell that can be smelled is also a kind of breath!
When they mix together, it becomes a unique breath in the world!
The Thousand Shadows Lake is very big, and the stars in the big sky are even bigger. Perhaps there is a burning smell in many places, and some places are also emitting a bloody smell... But the combination of the two, coupled with different concentrations... makes them unique Up.
And the shadow of the hands at that time must have been contaminated with these auras, and there will be residues all the way on the way with Cao Tian away.
This is the clue that can be used to track!
Tianyin Compass can track the other party through such a smell, not necessarily the breath radiating from the body!
However, the time is still too long.
In addition, the speed of the black shadow leaving is extremely fast, even if the body is contaminated with smell, it is easy to be washed away.
It's still hard to track.
"Theoretically, it can still be tracked." At this time, Li Huoyu's voice came, "For example, if you open the eyes of the avenue, you can see some extremely tiny molecules remaining in the air, and they will stay where they were. Of course, it depends on how detailed your artifact is."
"No matter what, give it a try." Fang Yu held the sky guide compass in his right hand, instilling true energy into it and activating it.
"bass!"
The dim and dim sky-guided compass immediately burst into light!
"Om!"
A trace on the compass began to glow, forming a thread-like mark.
"Hey..."
A large amount of cyan light enveloped the surroundings.
In the blue light, you can clearly see that there are a large number of fine particles suspended on the piles of ashes on the ground.
These are the breaths of this pair of ashes!
"Wow!"
A burst of suction appeared in the middle of the compass, absorbing these particles into the compass.
"Om..."
At this time, the sky guide compass vibrated, and a brighter light appeared!
On its surface, the thread-like imprint glows constantly.
This process lasted for nearly ten minutes.
It wasn't until a clear spot of light appeared on the thread mark that the sky guide compass stopped shaking.
"found it!?"
Fang Yu's eyes were surprised, looking at the flashing light spots on the threads of the compass.
The center point is Fang Yu's current location, and the light point... represents the target point of the breath locked by the sky guide compass!
It's like a mark on the radar.
"We have to find this light spot, and there should be something to gain." Fang Yu said to Huaixu.
Huaixu nodded.
"go."
…
Following the light spot of the Tianyin Compass, Fang Yu and Huaixu flew all the way to the northwest.
Before long, he flew out of the area of Qianying Great Hunan and continued to fly northwest.
"According to this distance... Isn't it going to fly to the northwest area of Qianying Lake?" Fang Yu frowned as he looked at Tianyin Compass.
The two continued to move forward, faster and faster, gradually approaching the point of light on the compass.
They entered the northwest area of Qianying Lake.
In the end, the light spot is already in the center.
This shows that this is where that breath will eventually disappear.
At this time, Fang Yu and Huaixu were both above the sky.
The two swooped down and saw a huge area.
"It seems to be here!" Fang Yu glanced at Huaixu.
Huaixu's expression was extremely cold, and his eyes flashed with cold light.
The two fell from the sky.
Before landing, Fang Yu discovered that there was a huge magic circle in this area.
According to the instructions of Tianyin Compass, the aura disappeared completely after arriving here.
From this point of view, the shadow... finally came to this area.
And the magic circle in this area has cut off all the breath... or rather, removed all the external breath from his body for him.
"That's it."
Fang Yu and Huaixu landed and looked forward.
At this time, when the breath is released, it will also be blocked by the magic circle, and it is completely impossible to explore the internal situation.
But just less than a hundred meters in front of Fang Yu and Huaixu, there was a stone stele erected.
There are four characters written on it.
Emperor family circles.
"Emperor Family Realm?" Fang Yu frowned.
"Emperor's house... Beiliang Emperor's house?" Huaixu's face changed slightly.
"Have you heard of it?" Fang Yu asked.
"The old man of the Cao family... once mentioned the emperor family to me. He said that the emperor family is one of the two most powerful families in the Northern Liang realm." Huaixu said with a solemn expression.
"Emperor..." Fang Yu squinted slightly, looking at the stele in front of him.
Clan circles.
After coming to Datianchenxing, it was the first time I saw such a big family, and it was enough to set up a clan world.
It seems that it is indeed a big family.
But whether to find the murderer for Huaixu, or to find out whether the purple flame is related to the Ziyan Palace... Fang Yu has to enter the imperial family realm.
"Go in." Fang Yu said.
"There is a barrier here, how do I sneak in?" Huaixu frowned.
"Sneak in? No, we will go in openly." Fang Yu smiled and said, "They are the murderers and kidnappers. Why are we sneaking?"
With that said, Fang Yu stepped forward.
Huaixu immediately followed.
The two went to the stele and continued to move forward.
At this moment, a copper wall and iron wall suddenly appeared in front of him, blocking Fang Yu and Huaixu's path.
"If you are not of the emperor family's blood, you can't step into the emperor family world for half a step!"
A voice without emotion came to Fang Yu and Huaixu's ears.
Huaixu looked at Fang Yu.
Fang Yu smiled slightly, raised his right hand and pressed it against this wall.
"boom!"
The next second, there was a loud noise!
The terrifying infuriating energy blasted the copper wall and iron wall in front of him to an instant burst, exploding big pits on the ground!
"Go, let's go in." Fang Yu said.
