If the big colored bird knew that Ning Fei's thoughts now would be so depressed that he vomited blood, it wanted to say hello to Ning Fei and then take the demon pill, but what he said, could this guy understand? Isn't that bullying? Oh no, it's not bullying birds!

After entering the cave, Ning Fei found that the depth and complexity of this cave were far beyond his imagination, it was like a bottomless pit, and the mountain roads in this cave were intricate, just walking in the cave for almost five minutes, Ning Fei was already dizzy, if he was not allowed to use the aura, now push him back, he would be 100% unable to find his way back.

"What the hell? Spooky. Ning Fei was depressed while walking, the deeper he walked, the deeper he walked, Ning Fei would feel a chill, you know, with Ning Fei's current cultivation, it is already cold and heat, but even so, in this cave, he still can't help but wrap his clothes tightly, this is not an ordinary cold, to be precise, this is a kind of cold, a kind of cold that can penetrate into his bones!

"Is this the Yin Qi?" A flash of inspiration flashed in Ning Fei's mind, and his brows immediately furrowed.

As he walked, the little tomato that was walking in front suddenly stopped.

"What's wrong?" Ning Fei asked curiously.

Little Tomato turned her face to look at him, her eyes full of confusion.

Yes, the police dog is no longer effective.

However, the reason for this is that Ning Fei can also think that the yin qi in this place is so heavy, not to mention the little tomatoes, even if it is himself, he already has a feeling of losing his sense of direction, this kind of yin qi has slowly transformed into a magnetic field that can affect others, or rather, there is an energy field here, this energy field can destroy the brain thinking of other creatures, this is an invisible attack force, the attack is not physical, but spiritual power.

"Forget it, you better go in first." Ning Fei himself didn't have any problems, because he had cultivated spiritual power, and he had never slacked off, the energy field here would not cause him much damage, but the little tomato was difficult to say, for the sake of safety, Ning Fei decided to put the little tomato in the ring first, lest he regret it when something happened.

Little Tomato also seemed to realize that she couldn't help now, and after listening to Ning Fei's words, she just whimpered and nodded. The energy field here has already made the little tomato feel uncomfortable, and even it feels a kind of danger, which is normal, not to mention the little tomato, even Ning Fei feels a kind of danger.

After walking for a while, Ning Fei suddenly patted his head.

"This time it was really capsized in the gutter, no wonder the spirit beast did not hesitate to burrow into the cave even if it saw itself following closely, and the bird also knew the wonder of this cave, so it wanted to use this cave to trap me!" Ning Fei smiled bitterly, looking quite annoyed, no matter who was played like this by a bird, he would not be in a good mood.

Ning Fei was wondering, was he born with an enmity with animals, he had always been despised by the empty before, and then he had to serve the little tomatoes like a little ancestor, and now he was played by a bird, this went out of the cave, Ning Fei was embarrassed to say hello when he saw people, if this was spread out, he would have to be laughed at by others for more than ten years, right?

As soon as he thought of this, Ning Fei felt that his heart hurt like a tear......

After wandering around the cave for almost two hours, Ning Fei's heart was also a little impatient, and finally he reluctantly found that he was still lost in the cave, which made him a little helpless, after all, the energy field in the cave was too powerful, and it had interfered with his sense of his aura, so even if he went back, he didn't know.

"Damn, I really want to tear this cave down." As soon as Ning Fei had such an idea, he immediately dispelled it, what are you kidding, although he has the ability to demolish this cave, he has to be buried himself! He didn't want to die on the Sky Island!

"Don't let me find the bird, for when I find it, I'll have to pluck the feathers, and eat half of it, and half of it will be roasted twice!" Ning Fei said viciously, but now he said these words, the bird couldn't hear them at all.

In the end, there was really no way, Ning Fei simply stopped, after all, if he continued to turn like this, it was just consuming his physical strength, and it didn't make any sense at all, and now he was extremely aggrieved.

Sitting on the ground, he took a deep breath, began to run the aura in his body, and entered a state of concentration, he could only calm his mind first, in order to find the right way, he also realized that after two hours of futile searching, his heart has become more and more irritable, this is not a good sign, if you can't adjust your mentality, then you are really likely to be trapped in this cave all the time.

Slowly, Ning Fei's cheeks, which were originally a little red due to impatience, slowly regained his calm, and when he opened his eyes again, his eyes flashed with fine light.

"If you can't demolish this mountain and make a hole, there shouldn't be any problem, right?" A chuckle appeared on Ning Fei's face, he stood up, closed his eyes, and took a step.

His speed slowed down a lot this time, and now that he closed his eyes, he couldn't do it even if he didn't want to slow down his speed, he didn't want to hit it with his head like the fierce beast that broke through the formation before, how painful!

After walking about a dozen steps, he stopped, and touched his hand in front of him, which was a stone wall. A sneer appeared on Ning Fei's face, and then, he silently recited the mantra in his heart, formed a handprint in his hand, and a spiritual aura burst out from his palm.

"Boom!"

With a loud bang, the wall blocking Ning Fei was forced to make a hole, Ning Fei got into it, and then continued to walk forward.

After walking for about a dozen steps, a wall appeared in front of Ning Fei again, and the previous method was concocted in the same way, but there was still a loud bang, and the cave fell into shaking again.

"Well...... Sure enough, this wall can also be pierced. Ning Fei's face showed a smug smile, I'm afraid that only he can come up with such a method, that is, close his eyes and walk forward in a straight line, and when he encounters an obstacle, he will directly use his aura to penetrate it. In fact, Ning Fei did this for no reason, there is an energy field in this cave, as I have said before, that is, that energy field, which can allow Ning Fei to grasp the direction, although his aura cannot be perceived, but it is his instinct to perceive that energy field, not to mention him, even if an ordinary person comes, he can feel that cold.

Anyway, they have lost their direction, so they simply regard that energy field as their goal!

After walking for almost three hours, Ning Fei finally stopped, and opened his eyes, not that he didn't want to continue walking, but in front of him, there was an extra force, like two mutually exclusive magnets put together, a wave of energy, was pushing him forward.

"Huh?" There was still a wall in front of Ning Fei, but he could see a few gaps in the wall.

"Stone Gate!" These two words flashed in Ning Fei's mind, and he was immediately excited, he didn't think that those fierce beasts and birds would make a stone gate, this stone gate must be made artificially, but who did it do? Looking at the Buck people, they obviously don't have this ability, and the most likely Kong Gongque will definitely not spend so long to make some tools to create a stone gate here, this is not something that can be easily done by one person, even if Kong Gongque is not an ordinary person, he may not have such means.

"Could it be that before myself and Kong Gongque, there were other Chinese people who set foot here?" Ning Fei had such a bold idea in his mind, this idea startled him a lot at first, but then he thought about it, and he could accept it, since he and Kong Gongque could come to this world, why couldn't anyone come before? Maybe it was hundreds of years ago, or maybe it was thousands of years ago, you know, at that time, there were many powerful people in Huaxia beyond imagination, and they were all in the realm of supernatural powers, and the realm of the Holy Dao was as many as dogs.

Therefore, with the strength of those people, it is not necessarily something that cannot be understood whether they can come to this world or come to this world in a group.

Ning Fei took a deep breath, picked up a wave of aura, and smashed it towards the stone gate.

However, after his burst of aura smashed on the stone door, it was immediately pushed back, Ning Fei was caught off guard, let that aura smash on his chest, his body immediately flew out upside down, and slammed on a wall, it took a long time to relieve his breath, and after wiping away the blood spilling from the corner of his mouth, he sat cross-legged and began to use his mental method to adjust his qi.

"It's really evil!" I don't know how long it took before Ning Fei slowly opened his eyes, he looked at the stone gate, his brows furrowed, this time he didn't dare to use his aura to attack the stone gate no matter what, it would bounce back! It was as if the stone door was a spring, and how much force I gave to the stone door, I also had to bear how hard it bounced back. It was only now that Ning Fei became more and more confident in his aura.

"Hey, if this gets out, I'll be the first cultivator to self-harm." Ning Fei smiled bitterly, and after getting up, he approached the stone gate step by step.

He walked forward, but an invisible force pushed him out.

"Could it be that there is some secret of the invisible man?" Ning Fei rubbed his temples, he was sure that the cold aura was emanating from behind this stone door, but as for what was hidden behind this stone door, Ning Fei didn't know, he didn't see it with his own eyes, he couldn't judge anything. His curiosity was not very heavy, but he faintly felt that there must be a secret hidden behind this stone door, maybe, what other good things, in case, there was something like a teleportation array that could allow him to return to Huaxia?

Thinking of this, he immediately became excited.

Be sure to get in! He said to himself silently in his heart.

It is imperative to get in, and the question now is what you have to do to get in.

His brows tightened, his eyes fixed on the stone door.

"Huh?" Ning Fei was suddenly stunned, "Outside this stone door, there seems to be a majestic aura?" ”

Finding this, he immediately patted his head: "I understand!" Outside this stone door, there is also a complex defensive circle, this circle is much more advanced than mine! Such a magic circle, even a cultivator of the Holy Dao Realm or a beast or a bird of fierce beasts, can't enter it, right? That Jiao, who has been cultivating for more than 1,400 years, is afraid that he does not have this ability, otherwise, this stone gate would not be able to exist here intact. ”

Thinking of this, he couldn't help but laugh.

Since this is a magic circle, there is a solution, I'm not afraid that it's complicated, I'm afraid that there is no way to solve it!
