Pu Yinglong''s sons are still cleaning up the battlefield, and Su Chen has come to the entrance of the fourth floor.


    "The border here is particularly powerful."


    Su Chen whispered to himself that he was not sure that he could open the boundary, but he was almost sure that the fourth floor and mingmeng road belonged to the same space. When he reached the fourth floor, there must be a way to reach mingmeng road.


    But even if Su Chen can break the border by force, it''s not appropriate for him to break in now.


    Although there are few demons on the fourth floor, they are demons at the level of Da Luo Jinxian. With Su Chen''s current strength, they must not be defeated.


    Su Chen turned her eyes to Donghuang purple.


    When will you stay without holding your thighs at this time?


    As soon as the Eastern Emperor Zi saw Su Chen''s expression, he knew what he thought. He said helplessly, "don''t expect me to help you again this time. I know a guy on the fourth floor. I''m not her opponent, let alone the other two demons."


    "Oh? Miss Zi knows the devil on the fourth floor? Can you tell me the origin of the devil?"


    The Eastern Emperor Zi didn''t shy away, and directly said, "the man I know, named Luo Ruxian, was once a general Ruxian, the most trusted subordinate of the Yan Emperor. Later, he was infected with collapse poison and degenerated into a devil, so he was suppressed by the Yan Emperor in the demon cave."


    Hearing that the collapse was highly toxic, the Taibai bright moon immediately showed a look of panic.


    She died because of the collapse and poison before.


    This poison has an unknown origin and contains the power of chaos and darkness. It once broke out in the fairyland for a period of time. Many immortals fell because of it. Even if they did not die, they would be infected by the power of darkness and degenerate into demons.


    She has heard of the name of the Prajna fairy, but she only knows that the Prajna fairy once had a high prestige in the fairy world, but suddenly evaporated and disappeared from the world. She didn''t expect such an encounter.


    "Like the poison in the bright moon?"


    Su Chen suddenly had a thought. When she revived the bright moon, only one third of the "anti collapse blocking life origin potion" bought by 30000 super skill points was used up.


    Even so, if the fairy is deeply poisoned, the remaining two-thirds of the medicine should be enough to cure her.


    If it''s not enough, buy another one. He can afford 30000 skill points now.


    Knowing that Taibai Mingyue was also poisoned by collapse, and was cured by Su Chen, the Eastern Emperor''s purple face showed surprise. He couldn''t help but look at Su Chen again: "this collapse poison, even Shennong was helpless at the beginning. You actually have a cure?"


    Su Chen smiled: "I have many advantages. Do you want to see it?"


    The Eastern Emperor purple blushed instantly, stared at Su Chen angrily, and said, "what are you going to do now? If you want to treat the Prajna fairy, I can help you."


    "Well, then."


    They have all come here. Su Chen must go to the fourth floor. Maybe he can get benefits by saving the Prajna fairy. Moreover, there are two other demons at the level of Da Luo Jinxian on the fourth floor, which can''t be dealt with by Su Chen''s strength. If the Prajna fairy can be cured first and her combat power can help, the threat of the remaining two demons will be greatly reduced.


    Su Chen didn''t talk nonsense. He sat cross legged and began to crack the entrance on the fourth floor.


    Several hours passed unconsciously.


    When Su Chen was about to crack it successfully, suddenly a violent tremor occurred on the earth.


    The huge vibration came from all directions, as if a big earthquake had occurred in the whole fairy world.


    No, not only the earthquake, but also the sky is shaking. To be exact, the whole space of the fairyland is shaking.


    "What''s going on?"


    Su Chen frowned and immediately asked Pu Ying to go out to check the situation.


    Soon Pu Ying came back: "I don''t know, father, I don''t see anyone''s breath around, and it''s shaking in the distance. The source of the vibration seems to come from the north."


    "North? Isn''t this the north of the fairyland?"


    "There is also an area in the north, which does not belong to the fairyland, and the time and space are disordered. Even Da Luo Jinxian dare not approach rashly. It is the most mysterious and unknown area in the fairyland," Pu Ying explained.


    Where the great Luo Jinxian dare not approach?


    Although Su Chen was curious, it was not the time to care about these problems. The vibration lasted for a short time and ended. Su Chen continued to crack the boundary on the fourth floor of the demon cave. After another half hour, the boundary finally loosened with a crisp sound.


    Su Chen took the lead in crossing the border and entering the fourth floor.


    Donghuangzi followed.


    "What a depressing atmosphere."


    "What a gloomy energy fluctuation."


    As soon as Su Chen entered the fourth floor, he felt a terrible pressure, which made him almost out of breath.


    Su Chen hurriedly said to Puying and others: "you stay outside and don''t come in. It''s too dangerous here."


    After calming down, Su Chen lit up the fourth floor space with the holy light of heaven.


    This is the interior of an abyss, the top of which is covered by a strong boundary. In the abyss, there are ruins and walls everywhere, as well as unknown skeletons all over the ground. It is impossible to distinguish what species they were in their lifetime by shape, but these skeletons have one thing in common, that is, they contain a strong smell of darkness.


    Su Chen urged the dark law to protect himself and isolate the dark power with the dark power.


    But this made donghuangzi show a surprised expression again.


    "How can you use the law of darkness?"


    "My heart is toward the light, even if it''s dark?" Su Chen said with a high sounding voice.


    The Eastern Emperor purple was speechless.


    What he said is reasonable. I don''t know how to refute it.


    However, now is not the time to care about this problem. Donghuangzi immediately launched a search on the fourth floor and soon determined the breath of Prajna fairy.


    She was thrown into the air by an iron lock made of cold ice, and there was a heavy and strict array around her.


    But it is strange that there are no other seals except here.


    "Aren''t three demons being held here?" Su Chen asked.


    "I haven''t been here before. How do I know what happened here?" said Dong Huangzi.


    Su Chen is not in a hurry to treat the Prajna fairy. There are too many arrays around her. If she approaches rashly, it is easy to stimulate these arrays. The lethality of some attack arrays is very amazing. Da Luo Jinxian may not be able to bear it. She must carefully untie these seals.


    But before that, Su Chen searched carefully in the abyss.


    "I really can''t find the trace that the other two demons were imprisoned. Is there only one Prajna Fairy on the fourth floor? Or are the other two demons escaped?"


    Su Chen suddenly looked at her head.


    He vaguely noticed that the border on his head seemed to have loosened.
