Murong Feng, who had transformed into a small flying insect, flapped his wings and flew over the heavily guarded city, only to see that this prison city was busy, and there were boxes of goods carried by shackled laborers everywhere.

Murong Feng landed on a box of unsealed containers and looked down, only to see that the boxes were stuffed with straw, and half of them were exposed, with big round black iron bumps exposed!

Murong Feng took a closer look at the attributes of this thing, and was immediately taken aback!

―――――――――――――

Murong Feng hurriedly flapped his wings and flew away from these large boxes full of bombs, if this fell into a spark, then the entire prison would be blown up to the sky. It's no wonder that the Black Dragon guards this place so tightly. Originally, Murong Feng thought that the Black Dragon Prince was just making some swords and armor to earn some pocket money, but now it seems that he still underestimated the ambition of that prince.

Murong Feng landed on the top of a tall pulley hanger, looking down at the mountains of containers in the huge square, and he was very suspicious that His Royal Highness the Prince would detain his own sister in such a place.

Boom! Boom! Boom! Suddenly, heavy footsteps came from a large cave at the end of the square. Then I saw an extremely burly and tall black dragon man walking out with a sharp spear nearly a foot long.

【Le Shrel】

Elite dragon leader

Race: Black Dragon

Health: 600000/600000

Level: 60

―――――――――――――――――――

Murong Feng immediately flew away from the pulley hanger and got into the window of a black prison.

I saw the black dragon commander Le Shrell carrying a spear with heavy steps, slowly looking for the orderly shipment work in the square. Suddenly, it stopped, sniffed its nose with its head raised, and in an instant its eyes flashed brightly, and grinned, "There are intruders!! ”

"Woo-!" The horn sounded.

"Bell, bell!" At the same time, the gong sounded!

For a while, the entire prison was alarmed, and countless black dragon guards swarmed out to drive the laborers back to the cages, and searched for the intruders everywhere.

Murong Fengzhi, who was hiding in the shadows, felt a cold sweat on her head, fortunately, she had seen Onyxia's perverted sense of smell, and just now she was blessed to hide in advance, otherwise she would definitely be directly discovered by the black dragon leader if she stayed in place!

Le Shreel stared at a pair of huge dragon eyes and slowly searched every corner of the square where people could hide, and suddenly it thought of something, and immediately summoned a team of black dragon guards to follow it around and rush towards the cave.

Murong Feng also breathed a sigh of relief when he saw the black dragon leader leaving, and then flapped his wings and flew out of the filthy cell towards the cave.

According to Murong Feng's thoughts, Onexia is the black dragon princess, and even if she is imprisoned here, it is impossible to be imprisoned with these laborers. And with that girl's strength, an ordinary cell will definitely not be able to lock her up.

Therefore, Murong Feng expected that the girl must be strictly guarded in a more heavily guarded place. Seeing that the black dragon commander was so nervous just now, there must be something important in that cave that needs to be guarded.

But when Murong Feng flew into the huge cave, he found that the passage in the cave was very deep, and it was winding downward, and there were four railroad tracks laid side by side on the ground.

Murong Feng flew all the way down these railroad tracks to the depths, and the further down he flew, the more he felt that the temperature was rising. It wasn't until I flew to the end of the passage that I suddenly found that there was a hole inside.

The huge mountain has almost been hollowed out, and the surrounding rock walls are filled with stone chambers of various sizes. Murong Feng stuck to the cliff wall and looked down, only to see a boiling magma lake at the bottom of the cave. Three lava giants about ten feet tall stood in the magma lake, holding a large special spoon in their hands, scooping boiling lava into the drainage tank nearby.

The lava flowed down the drainage trough into an artificially dug cave, and even from a distance, Murong Feng could hear the rumbling roar of machinery coming from the cave.

Although Murong Feng was very curious about the strange scene in front of her, she had not forgotten the purpose of her visit. So after glancing around, he flapped his wings and flew up the cave.

After searching for the layers of stone rooms, Murong Feng did not find Onexia, but instead saw many strange laboratories and manufacturing workshops. Remembering that the Black Dragon Prince had mentioned to Onexia that he was spending a lot of money on an experiment, and even had to resell arms to make up for it. Murong Feng had to sigh that His Royal Highness the prince was really hiding a lot of things!

Following the spiral disk road, Murong Feng flew all the way to the top floor, only to see that there was only one stone room here. But there are two black dragons guarding the door.

Murong Feng was thinking about how to sneak in, when he suddenly heard a loud explosion from inside. Then black smoke billowed out of the crack in the door.

The black dragon man guarding the door immediately opened the door, and then saw a group of grizzled dwarf engineers fleeing one after another, rolling on the ground.

"Ahh I'm infected! Scald me! ”

"Antidote! Antidote! Give me the antidote! ”

"It's too late, get the Freeze Jet!"

Several gnomes scrambled to pull out a strange spear and sprayed a cold mist at their companions who were rolling on the ground.

These writhing gnomes were immediately frozen by the cold mist, and they lay on the ground shivering and convulsing.

At this moment, another team of dwarf engineers ran out of the lower stone chamber and approached the companions and asked, "What's the matter?" The experiment failed again? ”

"Alas, don't mention it!" A grizzled dwarf engineer sighed, "The proportions of this colorful dragon's blood are too difficult to reconcile. We are not professional alchemists, and we can't fulfill His Highness's requirements! ”

"Alright, that's not something we should be bothering about. Hurry up and clean up this place and make a report. The dwarf engineer who came to inquire shook his head and turned away, apparently not surprised by such an experimental accident.

Murong Feng, who was hiding in the dark, silently watched as the dwarf engineers cleaned up the chaotic laboratory while treating their companions, and after waiting for a moment, he turned around and flew down. Sneaking in a stone room as soon as it opened, he turned into a dwarf in a corner around the bottles and cans filled with various liquids, and tiptoed behind a door to eavesdrop.

Hearing the complaints of a few dwarves coming from inside the door, Murong Feng gently pushed open a gap and saw that there were three dwarf engineers mixing some kind of powder on the door of the room.

One of them grumbled, and after quickly finishing the task at hand, he turned and walked towards the door.

Murong Feng immediately took a step back, quietly waiting for this dwarf to push open the door and come out.

The moment the door closed automatically, Murong Feng stretched out his hand to cover the dwarf's mouth and dragged him to the corner.

"I'll just ask you a question! Tell me, spare you from death! Murong Feng felt a dart against his throat, and then slowly let go of his hand.

The dwarf nodded again and again with a frightened face, but he was afraid that the movement would be too big and cut himself, so he could only swallow his saliva and tremble: "Who are you?" ”

"It doesn't matter who I am!" Murong Feng raised his eyebrows and asked in a low voice, "Do you know that the Black Dragon Princess is locked up there?" ”

The dwarf looked stunned and said, "Black Dragon Princess? How did the Black Dragon Princess end up locked up here? ”

Murong Feng frowned and asked again, "Then do you know if there is a place here that is dedicated to holding important prisoners?" ”

The dwarf nodded cautiously and said in an astringent voice: "I know, there is a cell at the bottom that is specially used to hold blood bags. ”

"Blood packs?" Murong Feng looked puzzled and asked, "What kind of monster is this?" ”

The dwarf twitched the corners of his mouth and said, "It's not a monster, it's just another name for those big guys." In fact, there are other dragons, including red dragons, blue dragons, and green dragons! ”

Murong Feng's eyes immediately widened, and he said in shock: "You are actually imprisoning other dragon clans? This was ordered by the Black Dragon Prince? ”

The dwarf smiled bitterly: "Except for His Highness, how can we have such courage and strength?" ”

Murong Feng took a deep breath and asked again, "What does the Black Dragon Prince want to do when he actually imprisons his fellow clan?" ”

The dwarf hesitated for a moment before replying, "Your Highness wants to create a new dragon clan that combines all the dragon abilities!" We call it the Colorful Dragonman! ”

Murong Feng was speechless, feeling that the Black Dragon Prince was really crazy!

"That...... I know how much, can you let me go? The dwarf asked tremblingly.

Murong Feng nodded, knocked him unconscious as soon as he stretched out his hand, and threw him in the corner. Then it turned back into a little bug and flew out of the lab through the vent and straight down.

The further down the temperature, the higher the temperature, when he approached the bottom, Murong Feng could no longer maintain his transformation state, so he could only find a hidden corner to show his original form to support the body protection qi, and then sneaked to the mouth of a big cave. Because there was a feeling in this cave that made her very uncomfortable!

"This is Longwei !!" Murong Feng settled down, and then lightly touched it inside.

The further he walked in, the more Murong Feng felt as if the air had frozen. It is conceivable that the wyvern imprisoned inside is definitely not an ordinary subspecies!

However, what made Murong Feng feel strange was that there was not a single guard guarding here.

As he got closer and closer to the bottom of the cave, Murong Feng felt more and more difficult to walk, and when he touched the entrance of the cave, he couldn't breathe normally!

Murong Feng leaned against the cave wall and looked inside, only to see that there were seven or eight large cages in the huge cave. Half of them are empty. The other half is holding an adult red dragon, an adult blue dragon, a juvenile green dragon and ...... Onexia!

It's just that they're all asleep at the moment......

Murong Feng took a deep breath, flew down and landed gently at the bottom of the cave.

Looking up at these super beasts through the huge steel gate, Murong Feng found that his legs and stomach were actually trembling uncontrollably.

Murong Feng bit the tip of his tongue and walked towards the cell where Onexia was imprisoned. I saw that the little girl still maintained her Lori form, lying on a soft big bed and falling asleep, grinding her fangs from time to time and smacking her small mouth, humming.

Murong Feng shook his head speechlessly, and lightly popped out a stone and hit the girl's head, but she didn't react, and she slept like a dead pig!

Murong Feng added more force and popped out a few stones one after another to hit this girl's body, but there was no reaction at all.

"It seems that this girl and these dragons should have been poured with some special coma potion!" Murong Feng pondered for a while, then looked at the steel gate in front of him. Reaching out and touching it and knocking on it, it was determined that it should be made of tungsten alloy, which seems to be called black iron here.

Murong Feng took out the Yuehua Sword and pulled it back and forth a few times, but there was not even a trace on the steel pillar. I tried the sword qi again, and I could barely cut through it, but the movement was too great......

Murong Feng was helpless for a while, and suddenly felt the back of his hand burn. When I raised my hand, I saw a skull flashing on the back of my hand!

Murong Feng's eyes lit up immediately, and he hurriedly sacrificed this legendary giant sword!

As a result, as soon as this giant sword appeared, it immediately began to frantically steal the vitality of several nearby giant dragons, and the frightened Murong Feng hurriedly transformed it into the 'embodiment of light'!

"It's up to you whether you succeed or not!" Murong Feng held the ash envoy and asked. saw the giant sword let out a sword roar full of resentment, as if protesting against Murong Feng not allowing it to suck it up.

"Well, when I rescue this girl, I will deal with a green dragon, and I will ensure that you can suck it up when the time comes!" Murong Feng hurriedly comforted.

The greatsword stopped, and then the gem on the back of the sword flashed, and a raging flame erupted from the blade.

Murong Feng took a deep breath and directly raised his sword to slash!

The flame blade slashed through the thigh-thick steel pillars without any hindrance, and three steel pillars were cut off with a single sword!

Murong Feng hurriedly stretched out his hand to support it, supported the fallen steel pillar with his mental strength, gently rested on the ground, and then quickly rushed into the cell and rushed to the bedside, picked up the little girl and walked out.

As a result, Murong Feng was carrying Onexia, who was sleeping like a dead pig, and as soon as she bent down and got out of the prison door, she suddenly stopped.

Nefarian, the Black Dragon Prince, stood there quietly, looking at Murong Feng with a helpless expression, and sighed lightly, "Priest Moon Shadow, this is not the place you should be. ”

Murong Feng turned his hand and carried the little girl behind him, and the other hand carried the ash envoy to the Black Dragon Prince politely: "Your Royal Highness, please forgive me for offending." ”

"Give up, you can't beat me." Nefarian said helplessly: "Don't forget, this sword in your hand was forged for you by this king." ”

Murong Feng asked directly, "Is His Highness willing to leave next?" ”

Nefarian shook his head and said, "I'm afraid not, because you've seen things you shouldn't see!" ”

"Then there's nothing to say, I just happen to slaughter a green dragon in the next place. If I can't even pass the hurdle of His Highness now, then I better not send him to death. Murong Feng flicked his wrist, and the golden ash envoy in his hand instantly rose with an eerie green flame!

Nefarian sighed lightly, and suddenly a figure flashed in front of Murong Feng, and directly blasted her whole person out with a punch, slamming it on the huge prison door with a loud bang.

The huge difference in strength between the two gave Murong Feng no chance to react! (To be continued.) )
