Xiao Yifeng entered this passage, went all the way down, I don't know how long, and found an underground cave.

In this cave, there is a demonic aura that is more than ten times thicker than the above, and the most important thing is that in the middle of this cave there is a long knife with a strange shape and various patterns.

At the hilt of the knife was a hideous ghost head, and the blade contained a monstrous might, obviously this was definitely not an ordinary weapon.

Even Xiao Yifeng looked at this knife with a trace of fear in his heart, but the outside of this knife was wrapped in a golden circle of light, as if it was a seal, sealing this knife here.

"It seems that those evil qi are produced because of this knife, even if it is sealed, it can still produce such a terrifying evil qi, what kind of weapon is this knife?"

Xiao Yifeng was secretly shocked, a strange look flashed in his eyes, and then his eyes looked around, and suddenly his eyes froze, as if he had found something.

He scurried out to the side of the cavern, where a pitch-black flower with a purple halo in the center grew, exuding a special energy.

The purple halo in the center of the flower emits a blurry light, which is beautiful for a moment.

But at this moment, Xiao Yifeng's face suddenly changed, and when his eyes swept away, he saw a black-robed figure appear in this cave.

"Nether Blade!"

"I didn't expect it to be the Holy Relic of the Ghost King Sect, Hahaha!"

The black-robed old man stared at the sealed long knife in the void, laughed, and then his sharp eyes swept away, and he saw Xiao Yifeng.

"Hey, I didn't expect that there is a little baby here, who can come here, and I am not afraid of the evil spirit here, who are you, boy?"

A cold glint flashed in the eyes of the black-robed old man, looked at Xiao Yifeng, and shouted coldly.

An invisible momentum enveloped Xiao Yifeng, which suddenly made her feel that she was restrained, and her whole body couldn't move.

The power in his body seemed to be imprisoned, and he was horrified in his heart, this was definitely a top master.

However, Xiao Yifeng was arrogant, so naturally it was impossible to give in like that, and looked at the old man in the black robe and said without fear:

"Who am I and what does it have to do with you!"

"Boy, have a backbone!"

The black-robed old man sneered, waved his hand with one hand, and a true qi power suddenly burst out, bombarding Xiao Yifeng's body, knocking him to his knees on the spot.

"You're a Condensation Realm master!"

Xiao Yifeng's face changed greatly, he looked at the other party in shock, and spit out a mouthful of blood, which happened to be on top of the black flower.

Suddenly, the purple halo on the flower was in full bloom, and then the unknown flower turned into a ray of light and poured into Xiao Yifeng's eyes.

Yes!

A terrible scream came out of Xiao Yifeng's mouth, and he fell to the ground, covering his eyes with his hands.

A sharp pain occurred in his eyes, and the pain made him feel like he was blind.

"Huh?"

Seeing this scene, a strange glint flashed in the eyes of the black-robed old man, but he didn't care, his eyes instead stared at the Netherworld Ghost Knife, and a blood-colored essence flashed in his eyes.

With a wave of one hand, a blood-colored light surged all over his body, and a blood-colored true qi burst out, blasting out towards the golden aura wrapped in the Nether Ghost Knife.

Rumble!

The blood-colored true qi bombarded the golden aperture, and immediately burst out with a terrifying energy aura, and the black-robed old man was even more shocked and retreated, his eyes showing a look of surprise.

"This seal is so terrifying!"

The black-robed old man was secretly surprised, but at this time he suddenly looked at Xiao Yifeng.

I saw that after a period of intense pain, the pain in Xiao Yifeng's eyes quickly disappeared, and he also felt as if something had changed in his eyes.

When his eyes opened, there was a purple light in front of him, and he couldn't see anything, which surprised him, and it was difficult for him to be blind.

Immediately after that, the purple light faded like a tide, and the cave in front of him appeared in his eyes again, but in the eyes of outsiders, Xiao Yifeng's eyes turned purple.

The purple eyes gave people a vague and dreamy feeling, and the moment the black-robed old man's eyes looked at Xiao Yifeng, his heart palpitated, and there was an inexplicable sense of fear.

Those purple eyes gave him an invisible oppression, and it gave him a sense of danger.

Eyes of the Dementor!

Suddenly, Xiao Yifeng's brain had an extra piece of information out of thin air, and this information turned out to be a special pupil technique that used his eyes.

The Eyes of the Dementor - Snatch people's souls and mess with people's minds!

Seeing the introduction of this pupil technique, Xiao Yifeng was shocked in his heart, this soul dementor eye was so powerful.

According to the above introduction, this soul eye is an extremely powerful pupil technique, once it reaches the highest level, as soon as others see his eyes, his soul can be absorbed by Xiao Yifeng and then controlled by it.

Terrifying!

Xiao Yifeng never thought that his eyes would become so powerful, and when he thought of something, Xiao Yifeng looked at the black-robed old man in the distance with his eyes and performed a soul dementorship.

The purple light in his eyes flowed, exuding a vague and dreamy brilliance, and the black-robed old man looked at Xiao Yifeng's purple eyes, and suddenly felt that his soul was about to float out, and he subconsciously lost his mind.

And it worked!

Seeing that this master was stunned for a moment, Xiao Yifeng was shocked.

However, at this time, the black-robed old man was covered in blood, and his eyes instantly regained their clarity, but Xiao Yifeng felt a terrifying force attacking, his body trembled, and a mouthful of blood spurted out again.

"Boy, what are these eyes of yours? Could it be some kind of magic?"

The black-robed old man's eyes stared at Xiao Yifeng with a look of vigilance and surprise, and his body was full of terrifying blood.

Xiao Yifeng fell to the ground, coughing violently, his face turned pale, although his soul dementorship and his eyes were powerful, but he had just obtained this soul technique.

He couldn't deal with an existence of the level of the black-robed old man at all, and he felt a little sad in his heart, could it be that he was going to die here today.

It's so aggrieved, I finally got a little gain, and I have to die like this.

"Not good!"

At this time, the black-robed old man seemed to sense something, his face changed, and he quickly left here.

Xiao Yifeng watched the other party suddenly disappear, his expression was stunned, and his clairvoyance eye couldn't help but open, and in an instant, his clairvoyance eye penetrated the cave and covered the outside of the teaching building.

And the perspective distance has also become longer, so that you can see through everything within a kilometer radius.

In Xiao Yifeng's perspective eyes, he saw several figures exuding a powerful aura approaching this Tianhai University, obviously the black-robed old man sensed the aura of these people before he suddenly disappeared.
