The undead flames in the passage of the 'dungeon' burned more and more fiercely. The pen "Fun" Pavilion www.biquge.info the talisman on the inner wall of the passage, and the imprisoned undead ghosts in the text have become the best accelerant for the flame of the undead. The undead flames gradually spread throughout the passage, but the strange thing is that although the imprisoned undead ghosts on the inner wall of the passage were burned by the undead flames, the undead ghosts in the flames instead of letting out a terrified wail, but remembered a strange laughter. The laughter was high-pitched and harsh, but there was something sad about it. I could faintly hear a ghost whispering, "We're free, we're free.........!" Ha ha...... Hehe......"

The pearl of the dark green halo is still floating in the air...... At both ends of the 'dungeon' passage, two groups of people were paying close attention to the changes that had taken place in the passage.

The exterior of the 'underground palace' passage is more like a vast and vast cave space. Although it is underground in this cave, there is no lack of light. Up and down the cave, all kinds of craggy stalagmites that glow with various colors of fluorescence are scattered in all corners of the cave. It is not an exaggeration to compare this scene to a blessed land. And the 'underground palace' is the backbone pillar of this huge karst cave. Of course, there are many similar pillars, but in terms of form, they are not as huge as this 'underground palace'. The entire vast and huge karst cave space around the 'underground palace' is a world of its own, although this world is beautiful, but under the beautiful appearance is indeed the bloody killing of the 'underground palace'.

Over the years, countless creatures have been born in this 'cave world'. Originally, these creatures were accustomed to life here, even if some whimsical beings considered leaving this world. However, these different creatures have since disappeared inexplicably. And so the legend was born - those who offended the gods were punished by the gods.

Until one day, a monk who came here from the outside world broke this legend, and the whole 'cave world' changed completely. From this moment on, the creatures of the entire 'Cave World' became 'traitors'. Legend has it that the alien monk once successfully led the 'traitors' to conquer the 'dungeon' and took some of the 'rebel' leaders to another world.

However, the good times did not last long, and not long after the monk and the leader of the 'rebels' left, the 'dungeon' changed again. Some of the 'rebel' leaders and some of the 'rebels' who had been left behind actually raised their butcher's knives and slaughtered their former comrades. The bloody slaughter stained the land around the 'dungeon', and countless resentful spirits around the 'dungeon' wept and wandered unwillingly. At the same time, the 'dungeon' also underwent a mutation after completely absorbing those blood and resentful spirits.

The mutation has caused a winding corridor to form up and down around the 'underground palace'. Legend has it that walking along the promenade can hear the wailing and weeping of resentful spirits. And any creature that walks into the corridor is in and out. Legend has it that only a special mage with a special status can perform a special sacrificial technique to appease the evil spirits in this corridor.

And the passage of the 'underground palace' where Mu Bin is located is the resentful spirit corridor outside the 'underground palace', and it is also the only passage from the 'underground palace' to the outside world - the Jiuqu Corridor. 'Nine Curved Corridors' is the official term for 'underground palace'. Rebels outside the 'dungeon' call it the 'Death Corridor', and the 'dungeon' 'Nightmare City'.

Yes, the bloody slaughter did not completely exterminate the 'traitors', but rather made the 'traitors' unprecedentedly united. Although the 'dungeon' is powerful, this strength is geographically limited, and as long as it is far away from the 'rebels' in the center of the 'dungeon', it will become like a fish in water. After all, 'rebels' are the aborigines here. That's why the 'underground palace' is called 'Nightmare', because the word 'underground palace' is not known to these 'rebels' in the first place. The second is that the 'rebels' think that everything that has happened in the 'dungeon' is simply a terrible 'nightmare'. The third is that they believe that those 'traitors' who have died in the butcher's knife of their companions will be in a state of great anger, hatred and fear at the time of death, and that resentment will persist after death, and that some of them will become evil ghosts, while others will turn into "evil nightmares". Hence the name 'Nightmare City'.

"It seems that something has happened to the 'Death Corridor' of 'Nightmare City'! It seems that the undead sacrifice we are preparing needs to be postponed!" "Thousands of miles away from 'Nightmare City', a burly figure stood out of thin air and muttered to himself. I saw that the strange blood-colored veins in the sockets of this person's eyes were protruding, and the pupils exuded cyan light.

"You guys go check on the situation first......" orders from both ends of the 'Death Corridor' were issued at the same time......

At this moment, the passage of the 'Underground Palace', which was originally used as a protective barrier for the 'Underground Palace', had been completely wrapped in undead flames. The 'dungeon' passage gradually began to change under the refining of the undead flames. The 'dungeon' passage gradually dissolved, and gradually evolved into countless black rune characters. These talisman words turned into black and flowed towards the pearl of dark green halo. Within the pearl, on the palm of Mu Bin's hand, the countless Dao Dao black practices made of black rune characters were rapidly condensing. As the black path continued to condense, it gradually condensed into a black stone the size of a bean. The black horse training was still converging, and the black stone the size of a bean was also growing at the same time......

...... The shrill laughter combined with the glowing green flames of the undead was particularly eerie. Finally, the last 'Corridor of Death' was also reduced to nothing in the strange flames...... The laughter stopped.

In the air, only a pearl with a dark green halo still floats in the air...... Mu Bin was pleasantly surprised within the pearl. In Mu Bin's hand was a black half-foot square stone......

...... At the same time, a great battle was in full swing in the sky above the 'Ancient Tomb Labyrinth'.

"Hehe! It doesn't matter if you are the 'Year Spirit Stone' or the 'Year Stone Spirit' or something else? Now that you are in my 'Ancient Tomb Labyrinth', you will not be able to win against me! I think it would be better for you to agree to my suggestion. Otherwise......" Demon Sacrifice sneered.

"It's not your turn to judge my existence for a small 'spirit seal'. But that stinky boy is really too weak, he hasn't moved at all for so long, I really don't know why he is so confident and wants to break through the 'Guling Labyrinth' by himself......" Lin Feifeng said secretly in his heart.

At this moment, the sky of the 'Ancient Tomb Labyrinth' changed, and an orange-red sun suddenly appeared in the originally dark sky. Although this round of orange-red sun could not completely dispel the darkness of the entire 'Guling Labyrinth', this round of sun and the light emitted by Lin Feifeng's body reflected each other.

"How is that possible!?" the Demon Demon screamed.

"Haha! It seems that that kid is not too weak!It seems that I underestimated him!" Lin Feifeng was happy in his heart, but in an instant, Lin Feifeng had already appeared in front of the orange-red sun. Lin Feifeng's body flickered, and the whole person had already rushed into the sun.

It turned out that the so-called sun was nothing more than an open door to space—the gate of the 'Heavenly Palace'. As the existence of the 'Heavenly Palace' alongside the 'Spirit Palace' and the 'Underground Palace' in the 'Ancient Tomb Labyrinth', the 'Heavenly Palace' itself also has a certain degree of independence. Therefore, after Lin Feifeng entered the gate of the 'Heavenly Palace', the Demon Sacrifice Heaven did not follow into the 'Heavenly Palace' at the first time. For some reason, the 'Heavenly Palace' and the 'Underground Palace' in the 'Ancient Tomb Labyrinth' are forbidden areas for demons to worship the heavens.

"Damn! How could things have developed into this situation?! Do you really want to watch Mu Bin and the others turn the tables and fail...... Forget it, the demon kings who had contact with Mu Bin just now, it seems that I will also visit them one by one. As for the nightmare spirit beast...... What a trouble!" Demon Sacrifice Heaven said secretly uneasy in his heart......

...... At this time, Mu Bin's incarnation in the 'underground palace' was absorbing and refining the 'Nightmare' ghost in the medium space. In particular, the resentment and countless telekinetic information contained in the 'Nightmare' ghost were all summarized into the void palace in Mu Bin's body. This is mainly the TOEFL and the ring ring in Mu Bin's hand and the inclusion function left by Xiao Wu in the Void Palace in his body. In addition, Mu Bin also had to refine the black stones that had just arrived. Mu Bin believed that if he had refined this black stone, there should be new changes in the Void Palace in his body. Xiao Wu should also be happy to have new information resources.

Mu Bin, who stayed in the space, once again used the method of 'Gathering Spirit Condensation' to conjure up the appearance of Xiaoyaozi and appeared outside the 'Nightmare City'. After Mu Bin summarized and analyzed the sporadic grievances of the resentful spirits, he had a certain understanding of the past of the 'Nightmare City'. Mu Bin knew that this was not the best time to enter the 'Nightmare City'.

Just when Mu Bin was still thinking, several streamers had already dared to go to the place where Mu Bin was. Three of them came from within the Nightmare City, and five streamers came from far away from the Nightmare City. However, there is only one target they have locked, that is, Mu Xiaoyaozi, who has just appeared as Mu Bin's spirit clone.

"Doll, are you alone here, and do you see anyone else passing by here?" asked a scar-faced villain who had arrived first at Mu Xiaoyao's (Mu Bin) appearance. The scar-faced villain really didn't want to believe that the fifteen or sixteen-year-old boy in front of him would be the target they were looking for—the culprit who destroyed the Nine Curves Corridor.

"Well...... I don't know!" Mu Bin frowned when he heard someone call him a doll. Mu Bin knew that the current face was based on the incarnation as a reference, and the evolution was a little younger.

"Hehe! What a handsome young man, Shen Qi, don't frighten people!" a red-haired woman with dark blue skin then came and chuckled.

"Don't talk nonsense! Bring the people back to the 'Nightmare City'! That hateful rebel group is coming!" said the last blue-haired and blue-eyed young man in a cold voice when he arrived.

As he spoke, the figure of the blue-haired and blue-eyed young man swayed, and he had already come to Mu Xiaoyao (Mu Bin). But when the blue-haired and blue-eyed young man was about to reach out to Mu Xiaoyao (Mu Bin). I saw that one of the five streamers that was originally far away from this place suddenly disappeared, and the disappearing figure between the lightning and flint had already appeared on the side of the blue-haired and blue-eyed young man. Immediately after that, the two lightning-fast offensive and defensive battles were completed in the blink of an eye. The blue-haired and blue-eyed young man had been forced back by the comer, and he showed himself more than ten feet away from Mu Bin.

A beautiful figure appeared in front of Mu Xiaoyao (Mu Bin), and as soon as he stretched out his hand, he hugged Mu Xiaoyao around his waist. With a flash, he moved away with Mu Xiaoyao.

"Stop them! don't let them go!" shouted the blue-haired young man.

At the same time, the beautiful figure that had been moved away with Mu Xiaoyao was smashed back by a giant hammer from the void along with Mu Xiaoyao. It was the original scar-faced villain who delivered that thunderous blow. That giant hammer was supposed to be a space-type offensive magic weapon.
