The key hung on the wall behind him.

Feather Wind wanted to steal the key with the Phantom Snake, but Princess Yuyu said, "Let me come, I have a better way!"

As she spoke, she activated the Eye of the Cave and whispered to the janitor, "Deep sleep!"

At this time, I saw that the janitor's limbs sank a little, snoring like thunder, and he slept even dead!

"No problem, he won't wake up tomorrow morning!"

They walked in generously, took out the key, opened the entrance door, and put the key back in.

Then, sneak into the training ground and enter the cultivation space of the princess.

Yu Feng felt that it was indeed a place with extremely high aura density, and he didn't know how many times higher than his own space!

And Yu Feng couldn't help but wonder, the reason why Princess Youyou was able to be assigned such a high spirit space, in addition to her beloved appearance, was it also related to the relationship between her and Xuanyuan?

Yu Feng couldn't help but ask, "Is there any special relationship between you and Principal Xuanyuan?"

Princess Youyou suddenly sank her little face and said, "Hey, do you still want to dig it?!"

Yu Feng knew that he was speechless, so he had to laugh and said, "Okay, this is digging, this is digging!"

Then, he summoned dozens of phantom snakes, opened the hellfire spirit hell, blessed the hellfire on the phantom snakes, let them lean together, forming the thickness of a passage, and then used the snake eye technique to determine the direction of his cultivation space. The phantom snake began to drill in that direction in the set course.

Feather Wind Pan sat down, closing his eyes to control the direction of the phantom snake and the intensity of the hellfire.

He had to make sure that the hellfire could boil the earth, but not spread too much, and the project was so huge that it took a lot of physical strength, and after a while, sweat broke out on his forehead.

Fortunately, with a large amount of aura in the cultivation space as a supplement, Yu Feng was able to maintain this state of continuous development.

The phantom snake kept moving forward, and suddenly, Yu Feng's brows furrowed slightly and stopped.

"What's wrong?" asked Princess Ghost.

"Something is unusual. "The hellfire didn't burn the soil of that place, and it seemed that a steady stream of things were rushing over to stop the hellfire's advance. ”

"Really? something?"

"I don't know, we'd better go over and have a look. ”

"Alright, let's go!"

Feather Wind stood up, and walked along the path that had been carved out.

The area burned by the hellfire was charred black, with a diameter of one and a half meters, and it was very neat and consistent.

"Not bad!" said the princess.

But Hakaze has been thinking about what is in front of him, so he is not in the mood to appreciate his masterpiece.

They hunched forward, and as they approached the place, they felt a tremendous energy floating in the air, and their hairs and hair were drawn to the fluctuating energy, reaching out that way!

"What a thing, such a powerful magnetic field!" said the princess.

As they went deeper, they found that an unconventional circular space appeared in front of them, and the space suddenly opened up, and blue electric sparks and the like were constantly flashing inside!

"What is this?"

"This should be the legendary 'Land of King Spirits' with the highest density of spiritual energy!"

"The Land of the King's Spirit?" Feather Wind repeated.

The Netherworld Princess said, "The density of the aura in the 'Land of the King's Spirits' is too high, and the spirits gather into pieces and collide, which is the blue electric spark we see. The movement of the aura has a relatively regular trajectory, so it can form a space with a regular shape. ”

"The Land of the King Spirit!" Yu Feng recited silently again, he really didn't expect that he had found the Land of the King Spirit by mistake, even in this marginal area, he could feel that kind of rich energy fluctuations, and the aura here was many times higher than the cultivation space of the Youyou Princess!

No wonder the hellfire can't burn, the aura is constantly converging, the hellfire has been burning the aura here, the aura here is so abundant, it must be incomprehensible!

If you cultivate in this space, then the speed of progress can be imagined!

As soon as Yu Feng wanted to step inside, Princess Yuyu said, "Wait a minute!"

However, Feather Wind has stepped in!

At this moment, suddenly there was a crackling sound of electric sparks in the air, and a behemoth emerged from it, and pounced fiercely at Feather Wind!

Feather Wind was startled, and quickly summoned several phantom snakes and entangled them!

Only then did it become clear that it was a behemoth dog!

This dog is very different from ordinary dogs, its body is as strong as a bull, its whole body is covered with long black hair, there is a brownish-red mane on its back, from the back of the neck to the tail, the protruding part of the mouth is long and wide, it looks a little like a dragon's kiss, the teeth are extremely sharp, the canine teeth are long and curved, the limbs are extremely thick, the four claws are thick and powerful, the cry is similar to a lion's roar, the eyebrow arch is very high, the eye sockets are deep, the eyes are like charcoal, extremely vicious, and, most specially, it has three heads!

"Good boy, what is this!" Feather Wind's eyes widened, and he was extremely amazed.

"This should be a 'hellhound'!" Princess Yu said, "Because, it is said that the land of the king's spirit can attract some 'underground creatures'!" 'Hellhound' is the representative of the legendary famous underground creatures, it should be attracted by the powerful energy here, and came here through the space gate! This creature is very powerful, it is said that they are the servants of the god of death, and they have strong cultivation ability. Luckily, this doesn't look like a high-ranking vicious dog!"

"Hellhound! This creature really exists......"

At this time, the hellhound had already roared violently, tore the phantom snake that entangled him with his sharp claws, and then pounced on Feather Wind!

Feather Wind hurriedly threw out a phantom snake boundary wall to trap the hellhound, but the hellhound tore the boundary wall apart with a slap!

Yu Feng glared widely, my good man, what a powerful force this is, he can easily shatter the phantom snake boundary wall with one slap, that is the realm wall of the Mahayana sixth-stage level!

At this time, the princess also joined in, instantly opened the eye of the cave, and used the "Extreme Vacuum", and the hellhound was weightless and floated up!

However, at this time, only to hear a deafening roar from the three heads of the hellhound, the princess was shocked to take a step back, and the "extreme vacuum" was cracked in an instant!

Yu Feng was shocked, he didn't expect this vicious dog's skill to be so strong, it didn't seem to be as low as Princess Youyou said.

Feather Wind creates a lead blade that stabs at the Hellhound, but is shattered by its slap!

Then, Feather Wind summoned Yuri, and when it saw the creature, it couldn't help but sigh, and said, "Oh my God, how did this evil thing come out?" I can only resist it for you, this kind of thing is too high-level, I'm afraid I won't be able to hold it for long!"

Princess Youyou stood up, activated the "Ghost Pupil System" again and opened the Ghost Pupil System to the eighth layer, and then, barked at the vicious dog: "Hey, brute, look over here!"

One of the heads of the vicious dog looked at this side, his eyes revealing a fierce light, and the princess did not move, and used this moment to launch an illusion: "Mirage, deep sleep!"

Sure enough, the blazing light that had erupted from the eyes of the Hellhound's head disappeared, and gradually turned into chaos, and gradually closed its eyes, and the head also drooped down and fell asleep.

However, at this time, the other two heads did not have any effect!

Now Yu Feng knows that the thoughts and consciousness of these three heads are completely independent, but when fighting, the pace can be so consistent, which shows that its internal consciousness has a unified combat habit and battle plan.

Indeed, when the hellhound is fighting, the three of them have different division of labor, with one of them as the command center of the battle, while the other two are responsible for observing and listening, so that they can achieve comprehensive defense and attack.

If one of the heads is attacked or killed, the others will immediately take over as the command center.

Now, one of the heads was hypnotized by the princess, but the other two were not affected in any way, only to see them let out a lion's roar again, and the eyes on the hypnotized head slowly opened again, and in a few seconds it returned to its original coal-like state again!

Yufeng and Princess Yuyu were shocked, it was so difficult to deal with!

At this time, the hellhound was obviously enraged, and its three heads roared at Yuri and the Phantom Snake King, and the strong air currents that emanated from its mouth were like wind blades, blowing the two giants to a crumbling ground, and a series of openings appeared on their bodies, and then, the thick and advantageous claws of the hellhound slapped wildly at them!

These two giant creatures, which were already very fierce, were immediately torn to pieces and almost killed, and they could only retreat into their space in a defeated manner!

At this time, it turned around, and its strong and powerful tail twitched towards Feather Wind and Princess Yuyu!

Feather Wind felt the strength of this blow, and immediately used layers of lead walls to protect them, covering both of them in it, and Princess Yuyu also used the "Extreme Vacuum" as a double layer of protection, but, with a bang, the hellhound just had this tail, and all the defenses were smashed!

The two of them crashed out and hit the wall, Yufeng hugged Princess Youyou tightly, used his body as a meat pad, and hit the wall, hitting his head and bleeding, and his head buzzed!

Fortunately, there are so many layers of defense and the protection of the "War Spirit Holy Armor", otherwise, this time it would have to be sucked to death!

The power of Hellhound is so powerful!

By this time, the hellhound had pounced again!

Feather Wind struggled to stand up, and launched the Hell Dao Spirit Hell at once, the hellfire has been used up, and Feather Wind, who is surrounded by the Hell Dao War Spirit all over his body, intends to fight the Hell Dog with a fully open attitude, although there is still no chance of winning in this case!

Just when the hell dog was desperate, the hell path war spirit was wrapped around the string of small bells "Wisdom Eclipse" on Yu Feng's wrist!

At this time, the string of bells suddenly made a pleasant sound.

Bell bell bell ......

This sudden scene couldn't help but surprise Yufeng and Princess Yuyu!

And at this time, the vicious dog actually looked at Yu Feng suddenly stopped moving, the hair on her whole body stood up, her limbs trembled, and then, two steps back, three heads bowed to Yu Feng.

Then, its eyes dimmed, and its six coal-like eyes slowly turned into a normal water-quality eyeball, but its pupils still looked much more evil and domineering than ordinary dogs.

At the same time, the powerful, vicious aura that emanates from its body is slowly hidden, and its body is constantly shrinking, and then, two of the three heads disappeared and became a head, and finally, it became a cute dog that looked chubby and round and smaller than the ordinary dog's body, its coat color was smooth, spotless and clean, and the image just now was really different, at first glance, it seemed like a pet who ran out!

At this time, the little fat dog, who was still a vicious dog, ran towards Yufeng with a fart, and then rubbed it affectionately on Yufeng's legs, and made the kind of intimate sound when the dog saw its owner.
