After some friendly talks with the system, Su Chen had a strong interest and expectation for the system upgrade.


    However, he has to complete at least a dozen more daily tasks of the system before the system can meet the requirements of upgrading.


    With the urine nature of the system task, even if Su Chen relaxes the bottom line, it is estimated that it will take a long time.


    And it seems that this is not the time to consider these problems. Now we are in an uncertain situation. It is a problem whether we can leave the damn fog safely.


    Su Chen tested teleportation several times. He found that teleportation skills can still be used freely in the deep valley not covered by thick fog, but the teleportation range can only be in the deep valley and still can''t exceed the thick fog. It can be seen that the source of hindering Su Chen''s teleportation is these thick fog.


    Su Chen also wanted to move underground, but he gave up after testing the hardness of these black rocks.


    It''s too hard. Once it moves underground, it''s easy to be pressed into meat patties by high-density rocks.


    After thinking for a long time, Su Chen still didn''t think of a better way to leave here.


    "I''m ready."


    Fox youyou slowly opens her eyes. With the help of Guiyuan pill, the yuan force in her body has recovered.


    "Then seize the time to find a way out."


    Although Guiyuan pill still has a lot of reserves, it''s not a long-term plan to stay here. Even if there are dangers outside, we still have to fight. We can''t wait to die.


    The fox youyou nodded and took the initiative to come to him: "let me carry you this time."


    "No, I''d better carry you," said Su Chen.


    Fox youyou''s attitude is very firm: "my sensing ability is stronger than you. It''s more appropriate for me to find the way."


    Su Chen is right to think about it. After all, this safe valley was discovered by Fox youyou first. It''s really more appropriate for her to lead the way.


    Su Chen was no longer polite. He stretched out his hand to hold the fox youyou''s neck and took the initiative to lie on her back. At the same time, Hu youyou also rolled Su Chen up and fixed her with his tail.


    With a whoosh, the fox youyou jumped up and broke into the thick fog again with Su Chen on his back.


    The airtight mist enveloped the two people again. Su Chen directly surged up a divine refining fire to disperse the dense fog, and condensed a layer of flame boundary around them to resist the invasion of fog.


    The cultivation of fox youYou lunhai completely broke out, and took Su Chen all the way, all at full speed.


    In the twinkling of an eye, seven or eight hours have passed.


    Fox youyou always keeps moving forward at a high speed. Coupled with the plundering of vitality by the thick fog, her yuan power is consumed very fast. She has to swallow a Guiyuan pill almost every half an hour, which has consumed two bottles of Kung Fu.


    Su Chen''s continuous use of the fire of divine refining also consumes a lot of yuan power and spiritual power. Later, the recovery effect of the immortal picture can''t keep up with the consumption. Su Chen also had to start swallowing Guiyuan pill to keep yuan power in an abundant state.


    "Bang!"


    At this time, the fox youyou seemed to bump into something. Su Chen was shocked by the powerful impact, and subconsciously tightened his arms and hugged the fox youyou.


    "Where do you touch your hand!"


    The voice of the fox came with resentment.


    Su Chen smiled bitterly and quickly moved his palm upward. The soft touch from the palm of his hand made Su Chen''s mind ripple.


    "Increase the firepower and see what''s blocking the way ahead." Hu youyou said in a slightly wrong tone, but now the situation is critical, and she can''t take much care of it.


    Su Chen nodded. The fire of divine refining suddenly increased and burned through the thick fog in front. He saw a thick Amethyst wall blocking the way.


    Su Chen frowned: "this is..."


    Fox youyou also noticed and said, "it seems to be a magic palace. Keep your fire and I''ll find the entrance."


    "Good!"


    The demon palace was quite big. Fox youyou searched for a while before she found the entrance, but the gate of the demon palace was tightly closed and could not be opened with her strength.


    "I''ll come!"


    Su Chen''s divine pattern broke out, forcibly cracked the prohibition of divine pattern at the entrance of the demon palace, and finally opened the door in two minutes.


    The fox''s youyou body flashed and rushed in with Su Chen.


    Under the isolation of the demon palace, the thick fog outside couldn''t get in, and the vision finally recovered.


    Su Chen jumped down from the fox''s quiet back and carefully observed the surrounding environment.


    Behind the entrance of the demon palace is a wide palace. The palace seems to have been abandoned for a long time. There is a thick layer of ash on the ground.


    "There are footprints and they look very fresh," said fox youyou.


    Su Chen also saw that it was not so much the footprints as the footprints of some kind of beast.


    Su Chen bent down and twisted a dust. He could feel a strong magic Qi.


    "There should be an expert from the demon family who has been here for a long time. Maybe it''s just a few days. Maybe he hasn''t left yet. We have to be careful," Su Chen said.


    "Follow the footprints and have a look." Fox youyou immediately walked along the footprints.


    Su Chen followed closely.


    They walked through the hall and followed their footprints to a passage leading to the underground. When Hu youyou was ready to enter the passage, Su Chen suddenly pulled her back.


    "Be careful, there are prohibitions."


    Su Chen frowned slightly. There was a strong fluctuation of divine patterns at the entrance of the channel. It was by no means an ordinary divine pattern master could condense and engrave. At least it was a means only available to the divine talisman or even the top-grade divine talisman.


    It is very likely that the demon palace is the core of the thick fog array.


    Su Chen felt very tricky when he met this level of divine stripe array.


    "Can you crack it?" asked fox youyou.


    Su Chen said, "try it."


    After saying that, Su Chen urged the divine pattern to penetrate into the prohibition, and soon entered the state of an old monk, motionless, even breathing and heartbeat seemed to stop, becoming extremely slow.


    Fox youyou didn''t dare to be careless. He carefully observed the surrounding environment and protected Su Chen''s Dharma.


    "This little pervert, who looks frivolous and serious at the critical moment, has some unique charm."


    The fox whispered in her heart, and her cheeks rose crimson inexplicably.


    She quickly shook her head, got rid of her thoughts, and warned herself, "fox is quiet. Recognize the reality. You are more than 2000 years old. Don''t have any illusion of love. Men are big pig hooves and don''t deserve trust!"


    "Stab!"


    At this time, a spark suddenly came from the channel. Su Chen also opened his eyes and said, "it''s done!"


    The ban was simpler than he thought, but it took him ten minutes to crack it.


    Fox youyou''s face had returned to normal at this time. She didn''t say much and walked straight towards the inside of the channel.


    Su Chen urged the power of the holy Phoenix. The holy golden radiance shrouded his whole body and bravely followed him.


    The passage was long and narrow and deep. It took a long time to reach the exit.


    "Snore..."


    A thunderous snore came suddenly.


    Su Chen looked up and saw a huge creature with a green face and fangs lying on the ground and sleeping.


    "Demon... Demon God!"
