The originally cold Fall Key is now becoming warm, and that temperature seems to be continuously rising at an inconspicuous rate.

Mo Zhiyao's mind flashed through what the Lord of the Stars said that day, this Falling Key should be able to guide him to find the source of yin and yang that the Ancestral Realm powerhouse Qi Sea had transformed.

It seems that the key to the fall is indeed a guide. Mo Zhiyao's eyes were hot, and he was secretly worried in his heart.

"Dad, where are we going now?" Long Zhan on the side lazily leaned on a big rock, looked at Mo Zhiyao and asked. A small world in this fallen land, although it was transformed by that ancestral realm powerhouse, but now it seems that it is also quite vast. If you run around aimlessly, the chances of finding the source of yin and yang will obviously become extremely small.

Although there is no time limit for the opening of this fallen land, Mo Zhiyao and the others cannot slack off because of this. Because no one knows if at a certain moment will be forcibly kicked out of here. The methods of the powerhouses of the ancestral realm cannot be judged by normal thinking.

This can be seen from the test of the space passage.

Mo Zhiyao rubbed the Falling Key in his hand, raised his gaze, and looked in a certain direction. Because he found that only when facing that direction, the temperature of the falling key in his hand changed significantly. Moreover, from that direction, Mo Zhiyao also faintly noticed a trace of spiritual power fluctuations.

"Let's go in this direction first. Mo Zhiyao's eyes flashed slightly, and then said.

Regarding Mo Zhiyao's proposal, the two of them naturally would not have any opinions. The three of them sat down and acted without the slightest drag, and when they even set off into the air, they swept straight in that direction.

And not long after the three of them left, on the sky above the top of the mountain, the void was slightly turbulent, and a ghostly figure appeared, shocking that it was Mo Zhiyao who saw a vague spirit shadow in the space passage.

Mo Zhiyao didn't know that of all the Divine Domain powerhouses who entered the space passage, only he had seen this spiritual shadow. Everyone else just doesn't see them, they only hear them.

Looking at the direction in which Mo Zhiyao and the three of them disappeared, there seemed to be some fluctuations in the eyes of the spirit shadow. That kind of fluctuation, as if I was expecting something...

After a few moments, the shadow faded, and finally melted into the void completely, vanishing.

.........

After galloping for a moment, the horizon in front of him suddenly changed. There was no end in sight before, and finally there was an end. What greeted Mo Zhiyao's vision was an ancient forest.

And when the three of them got closer and closer to the ancient forest, Mo Zhiyao felt that the temperature on the Fall Key had obviously risen a lot. Moreover, the spiritual power fluctuations that were faintly detected before are gradually becoming clear at this moment.

"Be careful. Mo Zhiyao told the nine colors and dragon battles beside him, and then his speed slowed down, and his vigilant gaze pierced through the void and stared at the forest in front of him. And the dragon battle and the nine colors also immediately used their spiritual power to protect themselves, and at the same time let go of their spiritual sense and carefully launched their investigations.

The three of them landed on the edge of the ancient forest in front of them, and Mo Zhiyao's expression became solemn. Because of that kind of spiritual power fluctuation, at this moment, not only did it become extremely obvious, but it also faintly carried a hint of rage.

Taking a deep breath, Mo Zhiyao nodded to the Nine Colors and Long Zhan, and then took the lead and stepped into the ancient forest.

And when Mo Zhiyao's footsteps had just stepped into the forest, a mutation protruded!

"Whew!"

A huge black shadow suddenly rushed out from the side, bringing a gust of wind and roaring towards Mo Zhiyao. The powerful force directly shook the surrounding trees into powder.

"Humph!"

Mo Zhiyao's eyes suddenly sharpened, he snorted coldly, and with a flick of his arm, the powerful power erupted like a volcano and smashed the body of the giant shadow.

"Bang!"

The terrifying shock wave of power radiated in a ring, and the ground under his feet exploded into huge cracks. Within a hundred zhang, countless towering ancient trees were uprooted by the impact of that kind of force, and then before they could hit the ground, they were torn into pieces.

The shadow storm retreated, slamming into the ground. A huge circular pit appeared in an instant. The dirt is flying, and people's vision is blocked.

Mo Zhiyao waved his palm, and the strong wind dispersed all the smoke and dust in the sky. The appearance of the giant shadow that could not be attacked by sneak attack was also clearly reflected in the field of vision.

It was a strange-looking beast with a hard scale armor that was black and white. The limbs are thick, and the sharp claws at the tips are like steel knives, shining with a palpitating icy sheen. Behind him, a long tail with spikes protruding from it, and when it flicked, even the void seemed to be able to tear apart.

The majestic spiritual power ripples around him, but in the diffusion, it can perfectly blend into the surrounding environment, as if it can be integrated with the void.

Mo Zhiyao's pupils shrank slightly, and the spiritual power fluctuations that permeated this strange beast were shockingly comparable to ordinary early ancient days!

"Is this the unique life derived from this heaven and earth?" Mo Zhiyao's palm slowly clenched, and from the scarlet eyes of the opposite hair, he could see that the latter did not have too high spiritual intelligence, only extremely ferocious and violent!

Moreover, the aura of this strange beast can blend perfectly with the surrounding environment. This was also the fundamental reason why he had only noticed obvious spiritual power fluctuations in this forest before, but he couldn't accurately determine the specific location.

"Bluffing.......

The strange beast stood up again from the deep pit, let out a low roar from its mouth, and with a murderous scarlet gaze, it locked on Mo Zhiyao and the three of them.

In the next moment, the strange beast let out a strange roar, kicked the ground with all its limbs, and its body rushed out again, rushing straight to Mo Zhiyao!

"I'm coming!"

This time, before Mo Zhiyao could make a move, the dragon battle on the side rushed out directly. The palm of his hand was suddenly clenched, and the power of the dragon and phoenix exploded, and a punch was blasted out!

Long Zhan's current combat power is comparable to that of the middle of the ancient world, and a strange beast that does not have much spiritual intelligence is naturally not his opponent. The thunderous fist blasted out, crushing the void and slamming heavily on the latter's huge body.

"Whew!"

The figure of the strange beast rushing out was directly smashed down from mid-air by the strong force of the dragon battle. And before its body could hit the ground, the dragon battle had already appeared above its head.

Looking at the strange beast under him fiercely, Long Zhan licked the corners of his lips, and a touch of ruthlessness that did not match his age appeared on his slightly immature face.

"Die!"

With a loud shout, Long Zhan's body sank, and he directly hit the head of the strange beast with a punch. Terrible power, crazy explosion. Circles of visible ripples of power, narrow and piercing sounds, swept out in all directions.

"Bang!"

The ferocious look in the eyes of that strange beast instantly froze, and then its huge body exploded directly, turning into a billowing black and white aura!

The dragon battle punch was as fierce as this, and it was shocking that a strange beast with ordinary ancient early combat power exploded on the spot!

Looking at the majestic black and white aura that was transformed by the explosion of the alien beast, Mo Zhiyao's eyes flashed suddenly, and he waved his hands continuously, enveloping all those black and white aura, and then pressed it hard.

The nine colors and dragons on the side suddenly changed their expressions. I saw that the rolling black and white aura, after being highly compressed by Mo Zhiyao's means, turned into dozens of round ones, the size of a dragon's eye, and there was a black and white two-color pattern evenly distributed elixir on it.

An extremely mysterious wave emanated from those elixirs.

"This is ......" Mo Zhiyao's eyes suddenly became hot. "Yin Yang Pill!"

Mo Zhiyao's most important purpose in entering the Fallen Land was naturally to find the source of yin and yang, so as to condense the true Dharma body. Another task is to collect a large number of Yin Yang Pills.

The Lord of the Stars once told Mo Zhiyao that there would be some unique life in this small world. And the source of these unique beings is because of the yin and yang qi of that ancestral realm powerhouse.

The qi of yin and yang is actually the qi of chaos. The chaotic qi can open up the heavens and the earth and give birth to all things. And the heaven and earth that this Immortal Venerable has transformed has always been in a closed state, so the chaotic qi contained in it has not dissipated at all. These strange beasts evolved from the chaotic qi.

It's just that to Mo Zhiyao's surprise, after these strange beasts are scattered, they will actually return to their original origin form, that is, the chaotic qi. He also had a flash of inspiration before, completely out of a trying mentality, but he didn't expect that he really succeeded in compressing and condensing those chaotic qi into a yin-yang pill.

With his palms in his hands, Mo Zhiyao took those Yin Yang Pills in front of him. At this time, Long Zhan also ran back, and together with Jiuse, he looked at these Yin Yang Pills curiously.

Mo Zhiyao took one casually, and the power of absorbing it in his palm was released, and it was directly refined into his body.

"Crackle!"

A crisp strange sound sounded in Mo Zhiyao's body. Mo Zhiyao's body suddenly trembled violently, and a look of shock appeared in his eyes.

The torrent of chaotic qi transformed by the Yin-Yang Pill rushed and surged in the body like a terrifying wave, and everywhere it passed, the flesh and blood meridians, bones and skin of the whole body became extremely greedy, frantically devouring that chaotic qi.

An indescribable feeling of pleasure permeated his whole body, making him almost moan.

After a while, Mo Zhiyao's body, which had been trembling slightly, could be regarded as regaining its calm. An indescribable feeling, rippling all around.

This Yin Yang Pill only made Mo Zhiyao's cultivation almost negligible in his cultivation. But it was an indescribable mystical understanding that made him feel indescribable. And the end of that kind of enlightenment is the realm that countless people dream of, the ancestral realm!
