Cheng Yifan didn't immediately absorb the three spirit elements on his body, he knew that the meal had to be eaten one bite at a time. His spiritual root was reborn, and it was several times stronger than before, and he was already satisfied, and he definitely didn't dare to have any more extravagant hopes.

He put the three spirit elements back in his pocket, stood up, and began to explore the environment of the cave. He had a hunch that it would be much more difficult to get out of here than it was last time in Hantan.

Cheng Yifan did not stay in the cave, but walked out of the cave in the sun. Towards the light, this is the most basic consciousness of human beings, so his actions are very logical.

The first thing that surprised him was the waterfall that was more than eight zhang wide. The water flow of the waterfall is not thick, and there is a faint sunlight shining in; The waterfall fell extremely high, and Cheng Yifan guessed that his impact should be quite amazing, otherwise the water curtain would not all fall into the abyss.

He looked up at the sky, and there was nothing but the huge waterfall. He used his spiritual power to look up at the sky again, and his vision passed through the waterfall, but he was blocked by the thick rock formation. The rock formation was very thick, at least 100 meters, and even if he used his spiritual power, he still couldn't penetrate it.

Fortunately, now Cheng Yifan's spiritual power is stronger than before, and the spiritual root is not what it used to be, he increased the degree of spiritual power, and walked through the 100-meter rock formation with difficulty, and finally reached the ground, but in addition to water on the ground, it is still water.

Cheng Yifan had just recovered his spiritual power, and he didn't dare to use it in vain. At this point, his spiritual power was close to its limit, so he withdrew his gaze.

"Thousands of meters up to the platform, except for the rock formation, there is water!" Cheng Yifan had already guessed where he was.

The largest lake in Xishan, the Broken Flow Lake, traverses the north and south of Xishan, and does not know the bottom. There is a fault ditch in the center of the lake, which is like a knife cutting off the water, dividing the lake into two halves.

Cheng Yifan guessed correctly, at this time, he was thousands of meters below the Broken Flow Lake, directly below the fault ditch.

Knowing where he was, he stepped over the flowers and plants on the platform and came to the end of the broken end.

At the end, the water was loud and the wind was cold, and he tried to probe the depth of the cliff bottom, but found that he couldn't see the bottom even when he used his spiritual sense to the extreme.

Without the rocks, his vision could see at least six kilometers away, but he tried his best to see the bottom, so he tried to see through the waterfall in front of him, and his vision saw through the one-zhang thick curtain of water, and found that there was also an outer platform behind the curtain of water.

The platform is small, less than five zhang in size. Behind it is a circular cave, the diameter of the cave is not about two zhang, but it is very long and dark. Cheng Yifan roughly estimated the depth of the cave, no less than a kilometer.

The deepest part of the cave left the smell of living creatures, and the smell was very unfamiliar, and Cheng Yifan had never smelled it. And it was just a smell, not a breath, and it was clear that the creature was not in the cave at this time.

Since the lake is a cave, it is not surprising that there is a symmetrical cave at the waterfall.

Cheng Yifan was not surprised by this cave, but he was very worried.

"The owner of the smell?" He subconsciously thought that the creature would be terrifying.

He felt that there should be an exit from the cave opposite, or the creature would not have disappeared.

It's just that he doesn't think he has the ability to penetrate a huge waterfall, if it is just a cliff a foot away, he may be able to risk death. But the impact of the thousand-meter waterfall, he can imagine, and there is only one result of jumping off the cliff, that is, falling into the abyss.

"Thinking a little far!" He smiled self-deprecatingly, intending to withdraw his gaze. Looking back the way he came, he came to the cliff, and he unconsciously looked at the bottom of the cliff below.

This look is incredible.

At the bottom of the cliff, ten feet away, in the waterfall, there is a plant that resembles an orchid.

"Plants can grow in the waterfall that falls for thousands of meters!" Cheng Yifan was a little unsure, and after retracting his gaze, he thought about it, and he cast his gaze there again.

This time he saw it clearly, it was not an orchid, it was just shaped like an orchid. Its leaves resemble orchids, but they are much more round than orchids, and the leaves are very short, and they are erect, like the toad grass common in the countryside, but the leaves of the toad grass are very soft, and the leaves of the vegetation are very hard, and they look much harder than the leaves of orchids.

"Maybe it's because it's been resisting a huge impact for a long time, so the blades have mutated and become hard!" Survival of the fittest, the plant that grows in the extreme environment is naturally not ordinary, although it is just a toad grass common in the countryside.

"Toad's Eyeleaf?" When Cheng Yifan's gaze moved to the center of the leaf, his heartbeat suddenly accelerated.

It was two clumps of curled leaves, shaped like cabbage but much smaller than cabbage, white at both ends and reddish-black in the middle, like eyeballs.

Cheng Yifan has never seen the "toad eye leaf", and the reason why he thinks it is the toad eye leaf is completely guessed by the meaning of the word and the shape of the plant, but he feels that eight or nine are not far from ten, and the two leaves on the opposite side are the toad eye leaves.

He had just finished taking Baicao Dan, and he could find Toad's Eye Leaf so quickly, how could he not be impressed? It's just that his heart is moving, and he is not stupid enough to jump over and pick. Not to mention whether there are alien beasts to protect it, he can't pass through this waterfall alone.

With the experience of picking the fiery centipede last time, he knew that where there were strange treasures, there would definitely be strange beasts.

Thinking of the creature smell of the cavern opposite, he left the edge of the cliff and walked back to the cave.

Cheng Yifan felt that the way to get out of here was to look for it in the cave where he was. He thought that since the river in front of him could bring him here, it would naturally bring him back, so he did not leave in a hurry, but began to observe the cave.

Soon he became more convinced of his thoughts. It was a relatively dark place in the innermost part of the cave, a large round stone more than two meters wide, with a thick layer of grass ash on the top of the stone, which was five centimeters high.

Cheng Yifan guessed that this layer of grass ash was artificially paved, that is to say, it was not grass ash before, but grass, and it only turned into ash because of a long time.

In the corner next to the large boulder there were several incomplete sheets of cloth-like rags. The rags have also been around for a long time, turning to dust at the slightest touch.

There are signs that "once upon a time, there were people living here!" ”

From its simple arrangement, it is not difficult to see that this place is just a place for a certain hermit master to practice or rest.

"Maybe the man is just like him, just the unfortunate one who fell into this place."

However, he quickly dismissed this idea.

"Who would accidentally fall into the lake with a quilt?" He shook his head and smiled wryly.

However, the discovery of a human being here strengthened his belief that he could leave this place the way he came.

Then, he walked around the cave a few more times, and after making sure that he found nothing else, he ran back to the platform and looked around.

In this less than twenty zhang radius, he rummaged back and forth, down to every crack in the stone and every vegetation.

In the end, he found nothing, and the human who once lived there left nothing but the rags, not a single word.

It wasn't until there was no sunlight penetrating the waterfall that Cheng Yifan finally gave up the search, and he planned to follow the river tomorrow to look for it.

The reason why he didn't immediately look for a way out was because he felt that his spiritual root had just been repaired and was not suitable for overwork. Moreover, he still had three spirit elements on his body, and he wanted to absorb them at night.

Now what he lacks most is aura. Just having spiritual roots and no spiritual energy is like a growing plant that has been cut off from water and soil, and cannot be nourished.

He must break through to the second layer of the "General Energy Realm" as soon as possible, which is also the purpose of his entry into the mountain this time.

At night, Cheng Yifan began to absorb the spirit element. He only took two of them, but it took him the whole night. Among them, Lingyuan's aura value is too strong is one reason; Another important reason is that because the loss of spiritual energy is too severe, Cheng Yifan has to slow down the speed of spiritual absorption.

His golden spiritual root was like a bottomless pit, and no matter how much he filled it, he couldn't fill it. And every time the aura runs to the heart of the belly, most of it disappears.

Cheng Yifan felt that there should be a problem with his spiritual absorption practice, which led to the loss of spiritual energy.

He had previously learned from Wu Yi that in order to enter the first layer of spiritual power, "Tongxin Realm", ordinary people had to accumulate millions or even tens of millions of spiritual energy to break through, and in the future, every layer of aura needed would be more.

Because Cheng Yifan was a barrier incinerated by the Fire Lotus Mist, he didn't know how much aura he needed to break through to the second layer. Now, judging from his own spiritual absorption, Cheng Yifan deduced that he needed at least hundreds of millions of spiritual energy to break through to the second layer.

He didn't know that his golden spiritual root was different from others, and he didn't know that what he wanted to break through was not the second layer, but the third layer. He only thought that his potential was too poor, after all, there were too few people like Ye Qingshan who only needed ten million spiritual qi to reach the third layer and give birth to spiritual roots.

Although the result of absorbing the spirit was not ideal, he must have inhaled more than 100,000 spiritual energy, and Cheng Yifan's spiritual power had improved a lot compared to the past.

He stopped exercising, and when he opened his eyes, he found that it was the morning of the second day, and the sun was still as warm as yesterday.

After taking a nap for two hours, he resolutely jumped into the river and began his way-finding journey back.
