Ji Tianxing followed closely behind the man in black and left the city under the cover of night.
The man in black is extremely fast, agile, and very vigilant.
However, Ji Tianxing was stronger and stayed three hundred meters behind him without being noticed by him.
When the two of them left Zhongzhou City one after another and entered the mountains in the southern suburbs, it was already dawn.
A new day has arrived, a faint red glow appears in the sky, and the sun is about to rise.
The mountains in the southern suburbs are sparsely populated, and the tops of each mountain are shrouded in thick clouds and mist.
The man in black speeded up unscrupulously, passing through layers of clouds and mist, and flew deep into the mountains.
Ji Tianxing followed leisurely, leaving special marks along the way.
Through this observation, he finally saw the clues.
The figure and appearance of the man in black did not look like a demon, but a human.
Moreover, the man in black was speeding along without any trace of demonic energy.
This discovery made Ji Tianxing full of doubts, and he silently guessed: "This guy is not a demon, but a human?
Is there someone colluding with the demons and acting as a spy for the demons?
No, this is impossible, no human race will team up with the demon race and collude with each other."
Full of doubts, Ji Tianxing continued to follow the man in black, trying to find out what was going on.
Unknowingly, half an hour passed.
The man in black flew for more than four hundred miles, entered the depths of the mountains, and landed on the top of a thousand-foot mountain.
Carrying a gray-brown cloth bag on his shoulders, he stood on the top of the mountain for a long time, looking around carefully.
Seeing that there was nothing unusual around him and no one appeared, he finally felt relieved and hurried towards a patch of rocks halfway up the mountain.
He entered the rocks and used a secret technique to activate a formation. A dark cave entrance immediately appeared in the rocks.
He looked around for a few times, then quickly got into the cave entrance and ran into the cave as fast as the wind.
Ji Tianxing, who was hiding in the dark, could see this scene clearly.
After the man in black entered the cave, he flew into the rocks and observed the cave entrance at close range.
The entrance of the cave is not big, only two meters in diameter. The cave is dark and lightless, exuding a gloomy and cold atmosphere.
Ji Tianxing used his spiritual sense to investigate and found a trace of demonic energy surging in the cave.
"It seems like this is a magic cave. I'll figure out what's going on soon."
This thought flashed through his mind, and he felt a little hopeful.
Taking advantage of the protective formation at the entrance of the cave that had not yet closed naturally, he quickly got into the entrance and rushed into the depths of the cave as fast as the wind.
As soon as he entered the devil's cave, a cold wind hit him, and a rich bloody devilish aura surrounded him.
There was no light in the magic cave, it was dark and damp, and filled with an unpleasant rancid smell.
Ji Tianxing released his spiritual consciousness and used his spiritual consciousness to explore the surrounding situation while sneaking into the depths of the Demon Cave.
He could see that the structure of this demon cave was very simple, and it should be a temporary hiding place built by the powerful demon clan.
The winding passage extends into the heart of the mountain without too many forks and confusing paths.
Half a quarter of an hour later, Ji Tianxing entered the depths of the magic cave and finally saw the light.
Ahead is a wide cave, with a radius of more than fifty meters. The surrounding rock walls are inlaid with more than a dozen moonstones, emitting a hazy white light.
The cave was filled with cold demonic energy, condensing into a large mass of black mist, billowing in mid-air.
Ji Tianxing hid at the entrance of the cave, opened his thunder eyes and looked into the cave.
He immediately saw clearly that there was only one person in the empty cave, and it was the man in black.
When the man in black returned to the magic cave, he thought he was safe and no longer concealed his aura.
He placed the bag on his shoulder on the ground, stretched his arms and moved his limbs.
Then, he took out two pills and drank them, then meditated on the ground to refine the power of the pills and restore his own strength.
When he started practicing Yungong, Ji Tianxing used his spiritual sense to detect that he had the strength of the second level of Tianyuan Realm.
"A strong demon at the second level of the Tianyuan Realm is not enough to become the king of a certain tribe. At most, he is just an elite demon general.
This person is hiding in the demon cave, but there is no aura of demons in his body. It is really weird... What is going on?"
Ji Tianxing hid in the dark and observed, thinking silently, not in a hurry to show up.
He waited patiently for two quarters of an hour before the man in black finished his meditation practice and fully recovered his strength.
The man in black stood up and opened the gray-brown cloth bag, and took out a young human race wearing a brocade robe from the bag.
The young man was about in his early twenties. He was dressed luxuriously and had red lips and white teeth. He looked like a noble son from a wealthy family.
This person possesses the strength of the eighth level of the Yuan Dan Realm. He is obviously an elite member of the Zheng family and a young master with a high status.
However, this Young Master Zheng is in a coma and unconscious.
The man in black carried Master Zheng and grinned with a sinister sneer.
"Jie Jie Jie... It's not in vain that I spent eight days sneaking into the Zheng family and waiting patiently. I finally succeeded!
Second Young Master Zheng, your Zheng family is prosperous, has many masters, and is full of flesh and blood... I really look forward to your performance after returning to the Zheng family!"
After saying that, the man in black shook his hands and threw Mr. Zheng into the magic mist in mid-air.
"Whoosh!"
The unconscious Mr. Zheng flew into the magic mist and was immediately wrapped in the magic mist and suspended in mid-air.
The magic mist surged faster and shrank sharply, forming a dark brown magic cocoon that enveloped Er Shao Zheng.
The demon cocoon released strands of black mist, like tentacles, piercing into Er Shao Zheng's body and began to transform and erode his body.
Er Shao Zheng's body suddenly twisted and swayed, and there were many bulges in his skin, like little mice walking through his flesh.
The man in black also continued to wave his palms to release the black mist's demonic energy, and used some secret method to control the power of the black cocoon.
Unknowingly, half an hour passed.
The man in black finished casting the spell, and Er Shao Zheng's body was also eroded and transformed by the magic cocoon, and some subtle changes occurred.
At this time, the man in black took out a small black gourd from the space ring.
The small gourd is a unique Purple Yin Demon Gourd in the Northern Desert. It only grows in the extremely evil Demonic Holy Land. The material is very tough and can contain all kinds of monsters.
This kind of Purple Yin Demonic Gourd is favored and loved by powerful demons. It can be used to nourish demons and store demonic energy or various flesh and blood spirits.
The man in black opened the Purple Yin Demonic Gourd, grabbed it with his big hand, and pulled out a tiny purple-black Demonic Insect from the gourd.
That hideous-looking purple-black devil insect was the same devil worm that Ji Tianxing had seen before.
However, this devil's Gu is extremely small, only as big as a fingernail.
Its power is very powerful, and its speed is as fast as a stream of light. It flies out of the Purple Yin Demonic Gourd with a "swish", and flies towards the magic cocoon with a "squeak", and is about to get into Er Shao Zheng's body.
