In the past half a month, Cheng Yifan has been exploring the way in addition to practicing.

Every day he would go to the end of the river to find an outlet.

At the end of the river, he sometimes uses his spiritual sense to find a source; Sometimes they go into the triangular cavern and find out where the exit is. However, after persisting for more than half a month, there is still no progress.

Those holes were as numerous as stars in the sky, and no matter which hole he chose, he would never get out of the ground. Each entrance seems to lead to one place, and it seems to be separate from each other, without any connection. No matter which channel Cheng Yifan chooses to advance, he will eventually be forced to return when his spiritual power is exhausted.

However, in the past half a month, he has not achieved nothing.

Every time Cheng Yifan's spiritual power is exhausted, he can always inhale more spiritual energy than before. "The capacity of his dantian is getting bigger." Cheng Yifan guessed that this should be related to the golden spiritual root, because since he had this golden spiritual root, his dantian had also turned golden, and even the spiritual energy he had inhaled into his body was faintly glowing with golden light.

And his golden spiritual root body was also several times thicker due to the nourishment of the aura. There are also a lot more roots derived from the spiritual root, a piece of gold.

Far more than that, Cheng Yifan felt that the heart of his belly, that is, the location of the insect, where the breath of the creature was getting stronger.

He felt: "The aura here should also help the ancestor awaken. So, instead of worrying about the lost part of the aura, he meditated and practiced more diligently, and he really wanted to get out of here as soon as possible.

Early in the morning, Cheng Yifan woke up from his cross-legged sitting, and in the mild sunlight, he glanced at the rocks on the ground.

There are five "positive" characters carved on the rock with a knife, and the last "positive" character is still one stroke away from being written.

"Nineteenth day!" Cheng Yifan took a deep breath, feeling a little lost, he is a person who doesn't like to be lonely but is often forced to be alone.

"Maybe I should find an exit in a different way!" In the past nineteen days, Cheng Yifan has made countless attempts, but he has never been able to find an outlet from the end of the river. He felt that he must have overlooked something, maybe he was looking in the wrong direction? Or maybe you're missing something?

"If it's inhabited here, why isn't there anything else but the bed?" He had seen some lonely islands wandering, and knew that people were animals that were afraid of loneliness, and if no one talked to them for a long time, they needed to find something as spiritual sustenance and communicate with them, otherwise that person would be claustrophobic or crazy.

Cheng Yifan felt: "The person who lived here before would at least write something down in writing, even if the person was illiterate, he would leave some pictures or graffiti and other things, and it was obviously very unreasonable to leave nothing like now." ”

"Maybe there's something else here that the man deliberately hidden!" Thinking of this, Cheng Yifan didn't practice again, but looked around like the first day he just fell here. As for what you're looking for? Cheng Yifan himself is not clear.

He had searched almost every nook and cranny of the place, but he still found nothing.

"Digging three feet into the ground" is a perfect phrase to describe at this time.

And just as he was about to give up looking and walk to the edge of the waterfall, a familiar and terrifying aura was coming towards him quickly above the waterfall.

Cheng Yifan could naturally feel the breath, and he quickly fled into the cave. This time he did not flee further into the depths of the river, but stopped at the entrance to the cave. Because he knew that the creature had discovered him, he didn't think the creature could go into the depths of the cavern, and he wanted to see what that terrible creature was.

He held back his breath and waited quietly, gathering his courage. He was a little uneasy, but also full of anticipation.

A moment later, the terrible creature literally pierced through the waterfall and landed unabashedly on the platform. Cheng Yifan saw it really this time, and he was scared.

It was a giant creature, like the legendary unicorn, and like an ancient creature that had become extinct on the earth, "Pterodactyl".

The creature was more than ten meters tall and had four legs, the front two slightly smaller and the back two fat. As you can guess, it walks mainly on its hind feet.

It has a pair of giant wings on its back, like the wings of a bat, but they are thousands of times larger than the wings of a bat. When the wings are spread, they cover the sky and avoid the sun, like a boundless giant net; When the wings are folded, they are much smaller, and their posture is a bit like that of ancient swordsmen with two swords on their backs.

When the creature crossed the waterfall, it was the head that came out of the water first, so the first thing Cheng Yifan saw was not its huge body, but the eyes the size of a car lamp and a huge head. It was a skull he recognized, with long horns, fangs and teeth, and two long, curly whiskers hanging from its mouth, like the head of a legendary dragon.

If it weren't for the giant wings on his back, Cheng Yifan would have reason to think that it was the legendary unicorn.

And if you ignore his long neck, then its body shape is somewhat like that of the legendary Pegasus.

It's just that the pale blue dragon scales and the tail more than two meters long can't make people associate it with Pegasus.

Cheng Yifan preferred to believe that he was a pterosaur than a Pegasus, because his red yellow wings completely covered his pale blue dragon scales when he flew in the sky. If it weren't for such a close look, it would be no different from the legendary pterosaur.

"Snort...... Sneer...... "The unicorn-shaped creature gently fell beside the waterfall and snorted in the direction of the cave with a spray of water mist like the jet of an old ox. It's just that the sound is more than a hundred times louder than the jet sound of the scalper, which scared Cheng Yifan for a while.

After the creature snorted, it did not chase after Cheng Yifan, but squatted down by the waterfall, posing like a male lion demonstrating. It's just that its demeanor is different from that of the lion, it seems to be extraordinarily calm and relaxed, and it doesn't take Cheng Yifan as a thing at all. From time to time, its tail twitched the waterfall behind it, and with each twitch, the waterfall was cut off instantly.

Cheng Yifan didn't hide in the cave immediately, because he was already very clear: "That creature knows about his existence." ”

However, no matter how terrifying this creature is, it can only be outside this cave, so Cheng Yifan is not worried.

That creature thought that Cheng Yifan would hide in the depths of the cave after being coerced, but he didn't expect that the human had never left. It doesn't seem to mind this, though. After sitting for a dozen breaths, it no longer wags its tail, but slowly spreads its wings, which have been protecting its chest.

Its movements are very slow and light, and it is very uncoordinated with its large body. It seemed to have something in his wings, and it gently placed the thing on the ground, and then slowly removed the wings, the whole movement as light as a mother putting a baby in the bassinet.

"It's a person, it's a person!" Cheng Yifan was not far from the creature, and even if he didn't use his spiritual power, he could clearly see what the creature had placed on the ground. It was obviously a man, a woman in a coma.

Cheng Yifan felt that the form and breath of the person on the ground were very familiar. A pure white tight-fitting undershirt, a yellow shirt on the outside, blue low-waisted jeans, thin waist and long legs, just like a modern person's dress.

"Bai Su?" Cheng Yifan couldn't believe his eyes, and the woman lying on the ground in front of him was dressed exactly like Bai Su he saw for the first time.

His mind went blank with a "whoosh", and he rubbed his eyes and looked at it again uncertainly.

This time he used spiritual power: "Without a single blemish, a face as smooth as a realm; blond hair with a thin short ponytail; The hair hanging down her temples was already soaked, and the water dripping from her face made her delicate face even more crystal clear. Strangely, her clothes and pants were dry, without a drop of water. Cheng Yifan guessed that it must be the strange creature that protected its body with its wings.

"But why is she unconscious? Isn't she in the Li family in the city, how could she be here? It's all unbelievable. The lover of his dreams, when he was in trouble, suddenly fell from the sky and was brought to him by a magical creature, which is too bloody. ”

"What do you want?" Cheng Yifan slapped himself in the face fiercely, and he scolded himself angrily in his heart: "When is it still thinking about it here." Then he did not flee again, but got up and walked out of the cave and came to the platform.

"Whether he is the opponent of this monster or not, he must save Bai Su." Cheng Yifan felt that any normal man would do this. Don't say it's Bai Su, if it were someone else, he would save it, but he couldn't be sure if he would be as desperate as he is now.

He forced himself to be emboldened, and came to a place only five feet away from the monster.

"Let go of that girl!" Cheng Yifan took the dagger and pointed directly at the monster squatting next to Bai Su.

The monster didn't expect the human hiding in the cavern to have the courage to come out. However, it clearly didn't take this small human in its eyes.

It raised its head slowly, looked away from Bai Su with some reluctance, and finally landed on Cheng Yifan's body inadvertently. "Porphyry...... Sneer...... "It snorted in the direction of Cheng Yifan and spewed out a white mist, as if to warn Cheng Yifan to leave.

Then it raised its neck up more than a meter, raised its head and looked down at Cheng Yifan condescendingly, the two curly whiskers on its face swaying gently with the breeze from the waterfall. He was still squatting beside Bai Su, wagging his tail sadly and whipping the waterfall, as if he was waiting for Bai Su to wake up.

"Stay away from that girl?" Cheng Yifan's courage came from nowhere, and roared at the monster again.

The monster still looked like no one was around, as if he couldn't understand Cheng Yifan's words, and it was as if he couldn't see Cheng Yifan.

Cheng Yifan didn't know that it was a kind of ignorance.

The creature didn't understand, "Why is this human here?" "However, it didn't take this human into account at all. In its eyes, Cheng Yifan is no different from dead alive. Even if it can't enter the depths of the cave at this time, as long as Cheng Yifan leaves the cave, it has full confidence that it will kill him. It's just to let Cheng Yifan live a little longer, so it doesn't care at all.

It's just that it still can't figure out why this human ran out and died on its own. ”

The monster shook its body, and the water droplets on its wings fluttered around, but not a drop fell on Bai Su's body.

It opened its mouth at Cheng Yifan, and "Roar ......" let out a roar containing anger. The roar was not only extremely loud, but also inexplicably trembling.

Cheng Yifan felt that this voice was very familiar, and it seemed to be very similar to the roar he had heard in the saltwater lake before.
