Is there a sound of flowing water?" Ye Fan was stunned for a moment, and then walked towards the sound of flowing water.

Sure enough, there was an underground river ahead.

The water of the dark river is not turbulent, it is somewhat like a stream, and it looks quiet.

On the other side of the undercurrent, there is still a river cave, which extends to a deeper level.

Ye Fan was stunned and decided to change his route and move along the underground dark river.

Because of an undercurrent like this, there will definitely be an outlet.

Ye Fan walked along the riverbed of the dark river for half a burnt incense, the riverbed gradually narrowed, and the dark river also completely entered the rock.

Ye Fan hesitated slightly, and plunged headlong into the underground dark river.

Now, Ye Fan has recovered a trace of true yuan in his body, although it can't function yet, it is enough to maintain internal breath.

The water of the dark river was very cold, probably close to freezing, and when Ye Fan jumped in, he only felt shivering all over his body.

Fortunately, the physique of immortal cultivators is different from that of ordinary people, otherwise it is very likely that there will be muscle spasms.

Ye Fan couldn't run the True Yuan, so naturally he couldn't use the True Yuan to keep out the cold, so he could only let the cold of the river spread all over his body.

However, after a while, Ye Fan discovered a wonderful thing, the speed of the recovery of the true element in his body was actually improved under the stimulation of the cold, although the increase was very small, but it was really improved.

Seeing this, Ye Fan was suddenly overjoyed in his heart.

"It seems that there will be three more days at most, and it should be able to recover!" Ye Fan said secretly.

Without thinking too much, Ye Fan continued to move forward.

......

On the other side, Wu Yunfeng returned to the place where Ye Fan's aura had disappeared, and then followed the big river, going upstream, looking all the way.

However, after searching for a long time, Wu Yunfeng did not gain anything.

"Where are the people?" Wu Yunfeng roared, angry in his heart, he was actually teased by a guy in the early stage of foundation building.

However, at this time, the strange beast lion beard who had gone to fight the Jiao Demon King flew over.

"Lion-haired senior......" Seeing the strange beast lion's hair, Wu Yunfeng couldn't help but feel guilty in his heart, and he didn't know how to explain Ye Fan's escape.

"Don't talk, take me back to the Water Moon Sect first. The alien beast lion beard said.

Then, I saw him spit out three mouthfuls of blood in a row.

"Lion-haired senior, are you injured?" Wu Yunfeng was taken aback, this lion-haired senior was the third master of their Water Moon Sect besides the ancestor and the head uncle, how could he be injured? And he was so seriously injured? Could it be the Jiao Demon King?

The strange beast lion wiped the blood from the corner of his mouth and said, "I still underestimated the Jiao Demon King, and he is worthy of being the King of Ten Thousand Demons of Canglan Mountain...... Wow......"

Before he finished speaking, the strange beast lion hair spat out another mouthful of blood.

"Quick, take me back to the Water Moon Pie. The beast lion's beard urged.

"Yes, Lionbeard Senpai. Wu Yunfeng answered, and he didn't care about continuing to search for Ye Fan's whereabouts, so he immediately rushed back to the Water Moon Sect with the strange beast lion beard.

......

The other side.

The Jiao Demon King was actually not lightly injured, with a lot of scales knocked off his body, as well as two fatal claw wounds.

At this time, he was recuperating in a pool of water.

......

In the blink of an eye, two days passed.

The true element in Ye Fan's body recovered, and the sequelae of the escape pill slowly receded.

Now, Ye Fan was able to run some True Yuan a little.

The river never had an exit to the surface, but there were a few caves along the way, but these caves were not connected to the outside world.

Helpless, Ye Fan could only continue to move along the dark river.

But fortunately, now Ye Fan has been able to run some True Yuan, which has doubled his swimming speed.

"I don't know where this dark river leads, it won't always lead to the East China Sea, right?" Ye Fan muttered secretly in his heart.

For the East China Sea, Ye Fan has heard of it, it is one of the most dangerous places in the Hidden Gate, there are countless krakens in it, and their strength is generally stronger than that of immortal cultivators.

In addition, Ye Fan also heard that there had been traces of a real dragon in the East China Sea, and he also heard that there was a dragon palace in the very deep part of the East China Sea.

It's just that there is no way to tell whether this rumor is true or false.

Regardless of these for the time being, Ye Fan accelerated forward.

Through the master-servant contract induction, Ye Fan can be sure that the black python is still alive now, and his sister Su Ningyue should be fine, the only thing that worries Ye Fan is the black tiger.

The black tiger's tail was struck by lightning, and his whole body was covered with lightning.

At that time, the situation was critical, Ye Fan didn't care about treating him, he just gave him some high-grade healing pills, and he didn't know what was going on now?

Before you know it, another three days have passed.

At this time, Ye Fan seemed to have come to the end of the dark river.

It is a hollow belly that leads all the way to the top.

But in the middle of this mountain, there is a huge tree, and the branches of the giant tree are so luxuriant that it seems to be hanging in the air, but if you look closely, you will see that the roots of the giant tree are firmly rooted in the surrounding mountain wall.

Ye Fan was completely shocked by the scene in front of him, he never thought that there would be a giant tree growing in the belly of the mountain, because it was too difficult.

Plants grow and need sunlight and water.

Water may not be an issue, because there is a dark river below, so there is a lot of humidity in the air.

However, sunlight is a big problem.

The entrance to the top of the mountain is very small, and when viewed from the bottom, it looks like a well, and the top seems to be covered by something, so there is very little sunlight that can shine in, and even if there is sunlight, it cannot directly shine on the trees.

Vegetation growth is inseparable from photosynthesis, Ye Fan really can't understand how this giant tree grows?

"Forget it, the world is full of wonders, let's get out of here first!" Ye Fan said to himself secretly.

Immediately, Ye Fan turned on the True Yuan and flew upward.

However, when Ye Fan passed by the giant tree, a thick root suddenly pulled out from the mountain wall, and then like a whip, it was whipped towards Ye Fan.

The sudden change startled Ye Fan.

"This giant tree has become a spirit?"

Ye Fan didn't dare to slack off, and immediately sacrificed the Qingfeng Sword.

"Ding......

There was a crisp sound, and I saw that the roots of the giant tree collided with the Qingfeng Sword in Ye Fan's hand like an iron tool, and made a crisp sound that only iron tools have.

After the blow, the giant tree did not attack again, but stared at Ye Fan with a vigilant look.

Ye Fan didn't know the temperament of this giant tree, and he didn't underestimate him because he was a giant tree, because in the world of cultivating immortals, a single grass can cut the sun and the moon, let alone a giant tree.

At this time, I heard Ye Fan clenching his fists and said: "Senior, the junior has no intention of offending, he just wants to leave this place by taking the pretext, and he also asks the seniors to fulfill it." ”

The giant tree seemed to understand Ye Fan's words, and saw him pull out half of the tree roots, and then the whole tree leaned against the side of the mountain wall, looking like he had deliberately made a way for Ye Fan.

Seeing this, Ye Fan couldn't help but be stunned, what a psychic giant tree.

Ye Fan didn't hesitate and said, "Thank you." He flew quickly upwards.

Sure enough, the giant tree didn't make any more moves against Ye Fan, and returned to its original position after Ye Fan left.
