After a long time, Xiao Nan finally opened his eyes and sensed the situation of his whole body incredibly.

The originally stable three-layer realm of quenching the body has taken a step forward at this moment, and the qi and blood around the body are like rolling rivers, majestic and majestic.

Not only that, but he stretched out his palm and ran the Yin Transformation Technique. I saw that the palm of the hand quickly became transparent, revealing the crystal bones. A cold aura condensed in the dantian in the chest, like an arm commanding.

Is this the "Xuanyin Body"? It seems to be very strange.

"Mother, Anan is fine. Don't cry...... "He took the exercises and wiped the tears of his mother, "Look, Anan isn't it good, Fang Cai's disappearance is just caused by the exercises." ”

Lan Xi pinched his left and right little faces, and when he saw that it was really fine, he finally broke into tears and laughed and put his mind at ease.

Xiao Nanyun used the Yin Transformation Technique, switched his whole body to the state of Xuanyin body, and leaned towards the stone wall.

The stone walls were soft and parted like water, enveloping half of his body in an instant.

"It's done!" he tried several times in surprise, and he could clearly feel that he could shuttle along the stone wall if he wanted to.

The extremely difficult Yin Transformation Technique recorded in the Beast Bone Book did not expect Xiao Nan to cultivate to the first layer in this strange cave in just two hours.

Next, it is to teach Lanxi to practice the secret of transforming yin.

Her cultivation realm is the fifth layer of quenching, which is slightly higher than Xiao Nan. But she doesn't like to practice, and she didn't know what spirit Gu she found when she was dripping blood to recognize Gu, and she never saw her use it.

After so many years, she has not been able to break through to the realm of witch refining with the help of the power of the Spirit Gu, which shows that the grade of the Spirit Gu is not high, or even extremely low.

Lan Xi sat down according to his words and practiced according to the mantra taught by Xiao Nan, but it went surprisingly smoothly. In just an hour or so, she cultivated into the Xuan Yin Body and reached the first layer of the Yin Transformation Technique.

This made Xiao Nan extremely surprised, could it be that his mother's talent was actually extremely high? He couldn't figure it out, and in the end he could only attribute the reason to the magic of this place.

"Alright, let's go!" Lan Xi's hands took turns to transform into the state of the Xuanyin body, like a child who had a new toy, very happy.

"With the Yin Turning Formula, our safety is finally guaranteed. Xiao Nan bowed his head and was full of confidence.

"If what I expected, there must be countless caves, and only one can actually get out. Let's find out!"

The two held hands and cautiously walked into the mezzanine of the stone wall. It was dark inside, and even the fluorescent grass was unable to emit light for some reason.

The dark distance was very short, and the two of them walked for a moment, and then they came to another almost identical cave as if out of the curtain.

"Sure enough, my guess is right!" Xiao Nan saw that the murals on the stone wall were exactly the same, and verified what he thought in his heart, and immediately felt a little more confident.

With the ability to shuttle through the cave, the two of them suddenly became more complicated and free. The next step is to identify which cave connects to the exit.

Xiao Nan looked around, looking for clues. However, this step is extremely difficult, and there is no trace of it.

"If I were the arranger, where would I put the birth gate?"

If the formation is really spherical, countless passages form a spherical maze. The globular maze is both rotating and orbiting, overlapping and overlapping, and I am afraid it is more complex than galaxies.

Xiao Nan speculated that he walked through the passages, measuring the distance, frequency, and radian, and seeing the big from the small, as if ancient scholars looked up at the stars and observed the changing rules of the solar system.

"This formation is mysterious and mysterious, as vast as a sea of smoke, it is really unfathomable!" Xiao Nan couldn't help frowning.

"Anan, don't worry, there will always be a time when things will turn around. You eat something first and rest for a while. Lan Xi saw that he was worried, he must have encountered some problem.

"That's fine. Mother, Anan has brought a lot of these silver tea cakes, and you can also eat some cushions. ”

He took out the dry food from the storage bag, stretched his brows, and sat under the stone wall with Lan Xi to eat.

"Anan, you don't have to worry, maybe the time has not yet come. Lan Xi comforted softly.

In the darkness, I couldn't see far away, only a faint light in front of me.

She sat upright in a plain white dress, although she was in danger, she exuded a sense of tranquility and warmth.

Anan understood. Xiao Nan smiled and nodded, slightly relieved, knowing that in the face of such a mysterious formation, it was useless to be anxious.

"It would be nice if Meng Yao was still there...... With her luck observation and magic ability to seek good fortune and avoid evil, she will definitely find a way out. ”

He bit into the silver tea cake, thought of it in a trance, and missed the person he hadn't seen for a long time.

"No, silver tea cake? yes, why didn't I think of it!" he suddenly jumped up and took the silver tea cake that he had bitten in half, stunned.

The traces of butter and honey on the cake are still there, accompanied by a little silver of camellias.

"Silver Tea Cake...... Silver Tea Cake ...... I'm like a camellia, trapped in this cake, just like this!" Xiao Nan jumped up suddenly, grabbed three silver tea cakes and looked through them repeatedly.

"Mother, you see, we are trapped in this formation now. The array is spherical and round in nature, isn't it like this little silver tea cake?"

"Huh?" Lan Xi looked puzzled, and his beautiful eyes looked at it, not understanding what was the mystery in the silver tea cake he made.

"Mother, you said that we are trapped in this silver tea cake, so where is the way out?" Xiao Nan murmured, his eyes turning from dark to bright, as if piercing through the darkness and welcoming the light.

"The way out...... Naturally, it's outside the cake?" Lan Xi thought for a moment and said uncertainly.

"Yes, that's exactly the reason! The way out is outside the cake!" Xiao Nan suddenly realized and laughed.

"Black & White Spectrum...... This is a black and white spectrum! If I were a person who set up the formation, I would definitely put the birth gate in the black spectrum outside the cave!"

"Black and white spectrum?Anan, what is black and white spectrum?" Lan Xi was even more puzzled.

"Mother, this black and white spectrum is an extremely rare one of the essence of the formation. You see, if that's the formation we're in. ”

Xiao Nan took a stone and outlined a circular area on the ground.

"The countless caves we passed through were like white lines all over the array, constantly changing. ”

He drew lines in the circular area.

"If you think of these caves as white lines, then the area outside the caves is black lines. Black and white crisscross and intertwine with each other, forming the entire formation. ”

Xiao Nan pointed to the white line and explained, using stones to smear the remaining area into a diagonal line.

"If you want to get out of this formation, I am afraid that you will never be able to get out of the cave marked by the white line.

"Only ...... Seeing the black line as a hidden cave and finding a way out of the black line is the real way out!"

"I see...... Then let's break the formation quickly!" Lan Xi's eyes showed surprise, not because of the hope of coming out of the battle, but because of Xiao Nan's wisdom!

I didn't expect ...... Such a complex and mysterious formation has been cracked by him!

"It's not enough to talk about breaking the formation, but now I have some ideas about the formation, and it's still far from really breaking the formation. Xiao Nan was not too optimistic, but shook his head and continued to think calmly.

He didn't say it, in fact, there was still a layer of worry in his heart: "The current formation is only the second change, no one knows if there is a third or fourth change in this formation, and whether it will be suddenly triggered......

"If you want to enter this black line, you have to have a Xuanyin body, it's a fluke!" he sighed lightly, stirring up the formation diagram on the ground, everything was already imprinted in his heart, "Mother, hold on to me, let's go in and try." ”

The two of them ran the Yin Transformation Technique, and they were about to drill into the cave wall. Suddenly, there was a fierce fight.

The two of them followed the prestige, only to see black shadows quickly appear in the mist.
