Pu Ying couldn''t hold the family''s persuasion after all. She bowed her head to Su Chen.


    "Father..."


    Su Chen smiled with satisfaction, touched Pu Ying''s head and said, "really good."


    After that, Su Chen waved his big hand and killed the remaining gray apostles.


    When the fog cleared and the valley returned to peace, Su Chen summoned the Xianlong family and asked about some things.


    It turned out that the branch of the dragon family in Longji mountain also migrated from Hongmeng universe many years ago. The blood of this dragon family was not strong at that time, but there was a super strong man with extraordinary talent in the family, who cultivated into the supreme ancestor dragon step by step. Only then did he fly to the fairy world, take refuge in Emperor Yan and become a strong family group guarding the North Tianmen.


    In addition, the Xianlong family also has an important mission, which is to guard the Fengmo cave in the north, which is the largest prison in the fairy world. It holds the heavenly demons captured by many immortals. Each of these heavenly demons has extraordinary background and strength. Letting one go will bring great disasters to the world.


    It is somewhat similar to mingmeng Dao.


    Pu Ying said, "father, we have just woke up. I don''t know what the situation is now. I want to check it as soon as possible so that the big devil inside won''t escape from prison."


    "Well, let''s go and have a look."


    To go to the Phoenix Palace, you must pass through the magic cave. Just go there and see what kind of big demons are held in the magic cave.


    If you can subdue several big demons, you won''t lose.


    In this way, Su Chen took a group of dragon children and women to the north, left Longji mountain and went straight to Fengmo cave.


    After walking for half an hour, Su Chen found a large area shrouded by fog in front of him.


    "No, it seems that those evil spirits have invaded the demon cave." Pu Ying''s heart is not good.


    Su Chen also saw some wandering figures in the fog, but they were not gray apostles, but some great demons with a strong smell of evil, but there was indeed the smell of the law of ashes on them.


    It seems that some demons have been taken away, just like the giant spirit outside the south gate.


    Su Chen no longer hesitated. With a big move, the chaotic clock was directly released, which soared a million times in an instant, enveloping the whole demon cave and preventing the evil spirits from escaping.


    "Good boys, come with me and clean up the demons inside first."


    Su Chen controls the rainbow horse, holds the immortal meteorite gun, takes the lead in charging, and directly enters the Fengmo cave. With a face-to-face Kung Fu, he blows through the body of a demon head.


    Wandering demons also noticed Su Chen''s approach and rushed over one after another.


    These demons are general. They only have the cultivation strength of fairyland. Although there are a lot of them, they do not pose a threat to Su Chen at all. The law of time is released. The action ability of these demons is greatly reduced and let Su Chen kill them.


    Even without Su Chen''s hand, his dragon sons can catch all these demons.


    The battle lasted only a little while before it was over.


    Su Chen urged the sky to shine the holy light and dispersed the fog around the demon cave with the law of light.


    At present, the entrance of the demon cave was finally revealed.


    "The array on the first floor of the sealed devil cave has been destroyed, but the array on the second floor seems to be complete. No wonder it''s just some little demons who haven''t met even a demon of heaven level."


    Su Chen asked, "how many floors are there in this magic cave?"


    "There are four floors. The first floor is the devil of the earth fairyland, the second floor is the devil of the heaven fairyland, the third floor is the devil of the gold fairyland, and the fourth floor is the devil of the Da Luojin fairyland. However, there are few demons of the Da Luojin fairyland, only three." Pu Ying said.


    Su Chen didn''t talk nonsense, and went directly into the first floor of the Fengmo cave.


    There must be other gray apostles in it. They must be removed as soon as possible.


    "The smell..."


    Entering the demon cave, Su Chen had some familiar feelings.


    The air of this as like as two peas of Ming and Meng, is just like a mold carved out.


    It seems that this demon cave is really related to mingmeng Dao. Maybe it was built by the same person.


    Su Chen suddenly had an idea.


    Is it possible that this demon cave and mingmeng Dao are connected with each other?


    You know, when Su Chen entered the fairyland, the tongtianxian road had been destroyed. Su Chen is now trapped in the fairyland. He can''t find a way to go back. Although he has plenty of time, he can''t delay in the fairyland for too long. After all, there is no waiting for the eternal night invasion.


    But if Su Chen''s guess is correct, he may find a way home in the demon cave.


    Of course, this is just a guess. It''s still unknown whether we can find it. In short, we''ll explore it first.


    The demons on the first floor have been cleaned up, so they appear very quiet and empty.


    It''s dark and gloomy here. The environment picks up leaks, but Su Chen notices the exquisite array arrangement here. Each divine pattern is so clever that Su Chen can''t help learning. He grabs a divine pattern and starts to study it.


    In a flash, more than an hour has passed.


    "Ding, congratulations on the host''s understanding of immortal pattern."


    Su Chen suddenly woke up.


    Actually understand the new skills?


    Su Chen immediately entered the skill library to check it.


    It turns out that this immortal tattoo is an advanced version of divine tattoo. Its power and complexity are hundreds of times higher than the top divine tattoo.


    Immortal tattoo is divided into nine grades. It needs 1500 super skill points to upgrade once.


    Not expensive.


    Su Chen is now worth more than 200000 super skill points. Even if she upgrades immortal pattern to grade 9, it is only 13500 super skill points. Sprinkle water.


    Without a word, Su Chen had a big hand and directly upgraded the immortal pattern technique to nine grades.


    For a moment, the brain knowledge information frantically poured into Su Chen''s mind.


    Hiss.


    Su Chen couldn''t help taking a breath. She just felt as if her head was going to explode and her brain seemed to be ignited.


    Su Chen felt better after a full delay of more than ten minutes.


    "Father, are you all right?"


    "Is the master well?"


    Pu Ying and rainbow horse came over and asked with concern.


    The Eastern Emperor Zi touched Su Chen''s forehead and said in surprise, "are you having an epiphany? And I actually understood so much knowledge once. I really want to cut your head and see what structure your brain is."


    Su Chen was very ashamed and said with a bitter smile, "Miss Zi, you''d better spare me."


    At least we''ve touched our thighs. We shouldn''t.


    He got up and recovered. Su Chen said, "it''s OK. How did you check?"


    Pu Ying said, "some gray evil spirits have been found at the entrance of the second floor, which have been dealt with. However, the array of the second floor has become loose, and the devil inside is crazy attacking the array. I''m afraid the second floor will be lost soon."
