Hao Yun took Fei Fei to dive into the dark river, the water turned out to be warm, it seemed that it was affected by the underground volcano, and swam along the water for a while, Fei Fei sent a message to Hao Yun, signaling Hao Yun to go back. Hao Yun asked why? Fei Fei gave him a blank look and asked him to feel the temperature of the water.

Hao Yun realized that the water temperature had risen somewhat, and he immediately understood that it seemed that going down the river might be a volcano, and if you want to get out, you must go against the direction of the water.

Hao Yun and the two swam back, Hao Yun's dragon tour world magic trick was not used many times, and he didn't put his kung fu here, fortunately, there were no water monsters in the dark river, and Hao Yun hugged Fei Fei upstream, which was not difficult.

Soon returning to the space where they had just been launched, Hao Yun and Fei Fei were originally more cautious, but suddenly felt that spiritual power was shaking from the space and transmitted to the water.

Hao Yun and Fei Fei were a little strange, could it be that someone was fighting, the two of them glanced at each other, Fei Fei pointed upward, Hao Yun would come to his senses, and carefully took Fei Fei to swim to the water.

After Hao Yun approached the water, he used the mirror trick to form an air mirror on the water, so that it would be safer to observe.

After Hao Yun operated the air mirror and turned in a few directions, he didn't find that there was a battle, and he couldn't see anything on the shore.

Suddenly, the vibration came again, and this time Hao Yun found the right position and pointed the air mirror in the direction where the vibration came from. I saw the rock above the space fall down, and then there was a vibration from above, and a huge rock fell from above, and the river rippled.

Hao Yun and Fei Fei looked at the air mirror in front of them and saw a figure floating down from the big hole above, holding a big knife in his hand, it was Feng Tianfeng and Senior Uncle Feng.

Hao Yun was overjoyed in his heart, and motioned for Fei Fei to go up to find Uncle Feng, Fei Fei grabbed Hao Yun, shook his head, pointed to the air mirror, and transmitted the message to Hao Yun, asking him to take a good look at Uncle Feng.

Hao Yun was a little nervous in his heart, is there something wrong?

Uncle Feng was holding a big knife in his hand, looking very cautious, as if he was guarding against something.

Fei Fei sent a voice: "It seems that there is an enemy, we can't venture to go up, and we can't stay in this place." ”

Hao Yun asked, "Then what should we do, don't look for your master." ”

Fei Fei said: "In this situation, we can't find my master, if Uncle Feng is attacked, my master will definitely not be better, otherwise the two of them should be together." ”

"There won't be several enemies, does the demon clan have such a great ability to mobilize so many demon clans, is there really a secret base of the demon clan here?"

"From this point of view, it is certain that there is a secret base of the demon clan here, but why do you want to detonate the fire spirit crystal, isn't this revealing your secret?" Fei Fei felt very strange: "Even if we are all killed, this place will be exposed, is it possible that the demon clan plans to abandon this place, but why wait for us to come here to implement it?"

"It won't really have anything to do with me, I didn't offend the demon clan!" Hao Yun felt a little aggrieved in his heart.

"It shouldn't have anything to do with you, maybe it's related to the vampire vine, could it be that this vampire vine is planted here by the demon clan. "Fei Fei always analyzes it in a set.

"If that's the case, this vampire vine is not ordinary, there must be a secret, it's not good, let's run away. Fei Fei's face changed drastically.

Hao Yun was taken aback by Fei Fei's words, but his subordinates were not idle, and quickly took Fei Fei to dive under the water and swim away quickly against the current.

"Don't go yet, I'm going to take care of it!" Fei Fei sent a message to Hao Yun.

"What's wrong?" Hao Yun asked.

"If you were a demon and you were looking for someone, what would you do?" Fei Fei asked.

"I must have watched all the exits around here. Hao Yun replied.

"You can't go forward with the earth. ”

"No, it's too deep here, the pressure in the soil is too great, and it's mostly rocky layers, don't say you can't walk fast, if you get stuck in the stones, it's a dead end!" Hao Yun shook his head.

"So, the only escape route here is this dark river, right?" Fei Fei's eyes rolled twice.

"It should be, I think the secret base of the demon clan should also be in the underground dark river space, and there should be other empty underground spaces where the dark river passes. Hao Yun guessed.

"If that's the case, we can't go up, and the big demon last time was from the water system, we are in the dark river, and it's not safe, we can only go down the water now. Fei Fei analyzed.

"But according to the water temperature analysis, it should be a volcano below, it may be a dead end!"

"We can see what's going on down there, and if it doesn't work, then we can think about going up. Fei Fei proposed.

"Well, just as you say. Hao Yun didn't talk nonsense, and quickly went down the river with Fei Fei.

Along the way, the water temperature slowly increased, Hao Yun especially used his divine sense to perceive the cave wall of the dark river, and found that the cave wall was a little hot, and it seemed that this place was not far from the underground volcano.

Suddenly, Hao Yun and Fei Fei's faces changed at the same time, the sound of water in front of them was loud, and the speed of the water began to accelerate, under Hao Yun's divine sense, there was a big hole under the dark river in front of him, and the water of the dark river also turned into a waterfall and rushed directly into the bottom.

Hao Yun asked Fei Fei what to do, can she go down directly? Fei Fei also thought and thought, and was undecided.

At this time, suddenly an object in the rear was accelerating and rushed in their direction. Hao Yun and Fei Fei were taken aback, and Master Li's voice came from their heads: "Hurry up and swim forward, there is an enemy behind." Hearing the familiar voice, Hao Yun hurriedly opened his spiritual power and rushed towards the void with Fei Fei as fast as he could.

With a "whoosh", two people rushed out of the water of the dark river, and what greeted them was a huge space, the water of the dark river formed a waterfall and fell into a lake, and there were large dilapidated buildings outside the lake, which was the remains of an underground city.

Hao Yun and Fei Fei couldn't believe their eyes, analyzing and analyzing, and they didn't dare to think that there was a city at the end of the dark river. The two men controlled their figures, flew to the lake, and landed.

The city has apparently been abandoned for many years, most of the buildings have collapsed, and it is covered in moss, and these underground plants emit a faint green light, making the remains of this underground city even more mysterious.

Master Li also rushed out of the dark river, and came to Hao Yun and Fei Fei's side in a moment.

"Are you hurt?" asked Master Li.

"It's okay, it's not a big deal!" replied Fei Fei.

"That's good, I didn't expect there to be a goblin ruin underneath here. Master Li sighed.

"What? goblin, it should be the demon clan!" Hao Yun asked.

"No, it's the goblins, the intelligent race of the ancient era of the spirit world, and they became extinct without knowing what's going on. "Master Li is sure.

Hao Yun felt that he had to study the history of the spirit world, and now there was another goblin, or an intelligent creature from the ancient era.

"The goblins are said to be very powerful, much stronger than the cultivators, how could they perish, leaving only some relics to reflect the glory of the past. Fei Fei also sighed.

"Didn't you say, there is an enemy, what now?" Hao Yun was in a hurry, did he have time to care about the goblins now?

"There is an enemy, after the explosion of the fire spirit crystal, the explosion caused the collapse of the mining area, and the two of you are nowhere to be seen, Feng Tianfeng and I can only find a way to dig down, but in the process of digging, we were attacked by the enemy, fortunately, the enemy's ability is average, so we were not injured, but Lao Feng and I were also forced to separate, and later I dug up and found the dark river, and found the mark left by Fei Fei, so I found you. ”

Hao Yun looked at Fei Fei a little dumbfounded: "When did you leave the mark, why don't I know?"

Fei Fei touched Hao Yun's head: "I left a mark on the wall of the Dark River Cave with my divine sense, this is a master's master's mastery, and only the master can detect it, so as to ensure that the master can find us." ”

Hao Yun smiled bitterly, did his performance make Fei Fei think he was a child.

"Can you be sure who the enemy is?" Fei Fei asked her master.

"I'm not sure, the enemies have blocked the soul frequency, and I can't be sure if it's a demon or a human. Master Li shook his head.

"How many enemies?" Hao Yun asked.

"There were three of us who attacked, and after I separated from Lao Feng, only one enemy chased me, and I had already been wounded and ran away. ”

"We saw Uncle Feng in the dark river, he was in one space to guard against the enemy, because we were not strong enough to dare to step forward. Fei Fei said.

"You were right to flee, when we were attacked just now, we found out that they just wanted to stop us from coming down to save you, so Senior Uncle Feng rose up to stop two of the enemies, so that I could find you as soon as possible. Master Li had a happy expression.

"Master, Hao Yun and I guessed that they should have targeted us because of the vampire vine. Fei Fei looked at Master Li.

"The vampire vine is still in your hands, right?"

"Master, look at it, there should be something wrong with this vampire vine!" Fei Fei took out the vampire vine and handed it to Master Li.

A red rattan glowed with bursts of red light under the reflection of a green light around it, as if it had come to life.

Master Li looked at it for a while and handed it to Fei Fei: "I'm not sure, this vampire vine shouldn't be an ordinary wood-based plant, I think you can try refining it." ”

Hao Yun looked around: "The scale of this city is not small, why hasn't the spirit world discovered it?"

"This city is right under the volcano, and if it weren't for the explosion of the Fire Spirit Crystal in the mining area, we wouldn't even be able to find out about this dark river. And cultivators generally don't dare to be interested in the relics of goblins, after all, they are all eliminated races, the spirit world has studied goblins for a period of time before, and found that this race cultivates the spiritual power of the dark attribute, which is particularly prone to spiritual damage, and the higher the strength, the more likely the goblins are to lose mental control, so there are a group of people in the spirit world who think that goblins are extinct because of their own reasons. However, the main reason is that there has never been a cultivator in the spirit world who cultivates the dark attribute, so even if he obtains the dark technique, no one will be able to cultivate. Master Li replied in detail.

Hao Yun understood, just like many waste exercises or tricks now, if you don't get it for the right person, it's worthless. So naturally, no one would focus on searching for goblin ruins.

"So what should we do now?" Hao Yun asked.

"Let's go around, the enemy should also know about this place, then there must be a secret in this place, everyone be careful, follow me!" Master Li was very cautious.

The three of them carefully let go of their divine senses and began to search for the ruins, and soon they found that there was an anomaly, the spiritual power in the underground space had a very unnatural flow trajectory, and the direction of the spiritual power pointed to the location in the center of the city.

After the three of them confirmed, they quickly followed the trajectory of spiritual power to the center of the city, and not long after, Master Li let out an oh sound, it should have been discovered.

In the center of the city is a square with a raised circular black platform with six white pillars enclosed in a circle, with a six-pointed star carved on the ground within the circle.

Master Li was amazed, it turned out that this black high platform was actually polished from a whole piece of ink jade, this high platform was about an acre square, and such a large piece of black jade was also rare in the spirit world. The white column is carved with white jade, and the top of the pillar is carved with six kinds of screaming beast heads, which are not known to everyone.

However, the pattern formed by the golden six-pointed star on the ground, Master Li came to the conclusion after careful study that this is a teleportation array, although it is somewhat different from the teleportation array of cultivators, but it is generally similar.

Hao Yun's heart moved, and he hurriedly asked Master Li where this teleportation array was pointing, can he be sure? Master Li found a charging device that could be placed in the spirit crystal at the root of the six pillars, and after putting in the spirit crystal, he carefully pondered it with his divine sense for a while, and Master Li determined that this teleportation array should be in the direction of Linghai City.

Fei Fei glanced at Hao Yun, and the two of them said at the same time: "I see!"

Master Li asked them what they had discovered, and they told them how the big demon had left the fairy forest silently after encountering the big demon, followed them to the Linghai side, and finally died at the hands of Doctor Liu.

Master Li stroked his beard thoughtfully.

"This teleportation array should be able to change the direction of teleportation, I'll see if I can change it so that this teleportation array can be teleported directly to Lingdu City, so that we can leave." Master Li said.

"We haven't reached the infant stage, can't we sit in the teleportation array?" Hao Yun was a little strange.

"You can't do it, but isn't it me? I'll protect you, though it will be more difficult, but it's better than being trapped here, I suspect that there must be an ambush at the outlet of the Dark River now, and there must be more than three enemies. "Master Li is also helpless!

The three of them had no other way, so they decided to gamble, Master Li began to modulate the teleportation array, Hao Yun and Fei Fei were on guard all around, not knowing when the enemy would come, they were now in a race against time.
