Ji Tianxing thought silently for a while, and then he had ideas and plans in his mind.
"After the people were corroded by the poisonous plague, their flesh and blood spirits turned into blood and energy, gathered in the sky and flew away.
Even a demon commander in the Soul Refining Realm cannot control the blood energy hundreds of miles away.
From this point of view, the Son of Blood God and the powerful demons are likely to be lurking hundreds of miles around Xunfeng City.
Or, they have set up some formation around Xunfeng City.
Xiao Han followed this clue to investigate, and he didn't find the formation or the Blood God Son, but that doesn't mean I can't find it either!"
So, he quickly flew back to the City Lord's Mansion and found Xiao Han and Xiao Ling'er.
The two of them were busy directing the overall situation and letting the people move into the underground city.
Seeing that Ji Tianxing was back, Xiao Han quickly came up to greet him and asked, "Tianxing, have you discovered anything?"
Ji Tianxing shook his head and said calmly: "Master Xiao, I have an idea that must be implemented as soon as possible.
I need a secret room where I can cast spells without anyone disturbing me."
Xiao Han immediately nodded and said: "No problem, I will send someone to make arrangements now!"
Soon, he found a secret room and rushed there with Ji Tianxing and Xiao Ling'er.
Ji Tianxing entered the secret room, and he and Xiao Ling'er stood outside the door, waiting patiently.
In the dark secret room, there was nothing else except an ice jade bed.
Ji Tianxing didn't care. He sat cross-legged on the ice jade bed, closed his eyes and started casting spells.
He held the spell with both hands, drew complex arcs and gestures, and murmured profound and obscure spells in his mouth.
"Swish, swish, swish!"
His entire body was gleaming with divine white light, emitting an unparalleled aura of strength.
After a while, I heard him shout in a solemn voice: "Dayan Sanqian, the soul is leaving the body!"
"Whoa!"
The Soul Sword that had been silent in his mind suddenly broke through his head and flew into the air.
The small dark golden sword quickly grew in size and turned into a golden sword more than three feet long, shining with sacred and bright golden light.
"This is the first time I've used it since I learned the secret method of soul leaving the body. I hope you won't disappoint me!"
Ji Tianxing's voice came from the Soul Sword.
He put his body into the world of swords and placed the broken sword on the ice jade bed.
Then, his soul sword flew out of the secret room with a whoosh and flew over the city lord's mansion.
Xiao Han and Xiao Ling'er, who were guarding the door of the secret room, saw a flash of golden light and a golden divine sword rushing into the sky. Their eyes widened with confusion.
The two looked up at the sky and talked in low voices.
"Uncle Xiao Han, did a divine sword fly up just now?"
"That's right, it's a golden divine sword. It should be Tianxing casting a spell."
"What is Brother Tianxing going to do? There are no demons or Blood God Sons in the city, who is he going to cast a spell to kill?"
"I don't know either. Let's just wait and see what happens and keep the secret room safe."
While the two were discussing, Ji Tianxing's golden sword spirit roared through the sky and flew out of Xunfeng City.
"call out!"
The three-foot-long golden sword soul was like a streak of golden light, flying to the northwest as fast as lightning.
He flew a hundred miles away, stayed in the sky for a moment, released the power of his soul to cover a fifty-mile radius, and explored carefully.
Whether it's the gray sky, the earth covered with fine sand and bones, or the dark depths of the earth, he doesn't let it go.
Ten breaths later, he searched a fifty-mile radius and found nothing.
So, his golden sword spirit flew around Xunfeng City, searching the surroundings of the city along the way.
About a quarter of an hour later, Ji Tianxing thoroughly investigated the entire area of a hundred miles around Xunfeng City.
This is not just digging three feet into the ground, but a search that goes thousands of meters underground!
Not even a mosquito or a hair can escape the detection of his soul.
But even so, he still couldn't find the aura of the demons, let alone any Blood God Son.
His sword soul paused in the air, thinking full of doubts.
"How could this happen? We searched hundreds of miles around and found nothing.
Could it be that a powerful demon can still absorb blood energy from hundreds of miles away? This is impossible! Only powerful formations can have such an effect."
He was unwilling to do so and continued to fly northwest.
He wanted to see where the dark red blood that covered the sky and the sun was going to fly.
A quarter of an hour later, Ji Tianxing left Xunfeng City six hundred miles away and entered a mountain range.
He found that the dark red blood energy above this mountain range became more and more intense.
The dark red blood mist that covered the sky not only came from Xunfeng City, but also several streams of blood mist came from different directions.
Obviously, the source of those bloody mist must be other cities and villages.
"This mountain range should be the intersection of blood and energy in the sky. The demons are likely to be hiding here."
Ji Tianxing's spirit was shaken, and he immediately flew into the mountains, releasing the power of his soul to investigate carefully.
The power of his soul covers a radius of fifty miles, no matter the sky or the ground, he will not miss even a stone or a blade of grass in the mountains, and will explore them all.
Before long, he searched an area of two hundred miles.
Finally, deep in the ground of a thousand-foot-high mountain, he discovered a clue.
In the rock layer deep underground, there is a man-made cave, only ten feet in diameter.
A Tianyuan-level formation is set up outside the cave, which can conceal the aura and make it difficult for warriors below the Soul Refining Realm to detect it.
And inside the cave, there is a small altar ten meters high.
The altar is in the pyramid shape commonly used by the demons, built with the skulls of human warriors, and is embellished with several Tianyuan formations, which have evil demonic effects.
Ji Tianxing observed for a moment and found that the demonic aura on the altar had not disappeared, and there were still strong fluctuations of magic power.
However, there should be a magic weapon on the top of the altar as the core of the altar.
But the top of the altar was empty.
Ji Tianxing immediately concluded that the powerful demon clan must have just left not long ago and took away the core magic weapon at the top of the altar.
"Damn demon bastards! They must have sensed my arrival and fled in a hurry.
My speed was fast enough, but I couldn't catch them. No wonder Xiao Han couldn't find them either!
However, the demon bastard must not have gone far, I should be able to catch up!"
When this thought flashed through his soul, his golden sword soul immediately left the cave and flew toward the northwest at lightning speed.
The speed of the sword soul is extremely fast, like an aurora piercing the sky. Even a strong man at the seventh level of the Soul Refining Realm cannot match it.
"call out!"
After just a few moments, the golden sword spirit flew five hundred miles away and arrived above a sparkling lake.
At the same time, Ji Tianxing saw a dense black mist flying across the lake below at lightning speed.
He used the power of his soul to investigate and immediately discovered that there were three Tianyuan realm demon kings lurking in the demonic mist!
