The dense mist rolls and surges on the earth, and the large particles in the mist constantly collide and rub with each other, making a slight Zizi sound. In addition, the whole world seems to have fallen into the end, and there is no other change.


    Su Chen and Hu youyou have been walking on the dark land for an hour, and hardly find any clues.


    Position, direction, all without a clue.


    Su Chen even felt that he had not fallen into the underworld.


    But think carefully, Su Chen''s soul has been to the underworld, and the underworld is not such an environment.


    Speaking of, the environment of hell is much better than this ghost place.


    "I''m a little tired. Don''t you think the fog will absorb our yuan power?" said the fox youyou weakly.


    "Yes, but it''s OK." Su Chen is still energetic. After all, he has an immortal plan to help restore yuan strength.


    The fox is quiet and speechless. Su Chen is not lunhai, but many places even surpass lunhai. It''s too abnormal.


    However, in this case, seeing that Su Chen is still alive makes the fox feel very safe.


    Otherwise, if both of them fall into a trough, there will be great trouble.


    "I''ll carry you." seeing that the fox was getting weaker and weaker, Su Chen simply squatted down and said.


    Fox youyou is not polite to Su Chen at this meeting. She wraps her tail around Su Chen''s thigh and turns over and lies on Su Chen.


    "Get some water to wash me." said Hu youyou. Although she was in a bad situation, she still didn''t give up her love of beauty.


    Su Chen smiled, took out the sea god Trident, and released a gentle current around the fox youyou.


    Although seawater washing will leave salt crystals, it is better than slimy ones.


    Su Chen himself rolled up the current and washed it.


    After another half hour, Su Chen still didn''t find any way out.


    The scope of the mist didn''t know how big it was, and she couldn''t tell the direction at all. Su Chen even suspected that they had been walking for a long time. In fact, they were spinning in situ.


    "It''s not a way to go on like this. Even if I have an immortal picture that can restore yuan power, over time, I will still be absorbed by these mist. If I can''t find a way out at that time, I can only wait to die."


    Su Chen took a deep breath and took a Guiyuan pill. In an instant, she frantically injected Yuanli into the Poseidon Trident. The artifact could not be fully opened, and a thick current burst out. Su Chen stepped directly on the current and moved forward rapidly along the current.


    At Su Chen''s feet, the fire of divine refining was burning at the same time, and even the ocean current was ignited to disperse the mist encountered on the way.


    Along the way, another hour passed unconsciously.


    Fox youyou is now extremely weak, and her yuan power is almost exhausted.


    Su Chen saw this and took out a Guiyuan pill to feed the fox Youyou, so that the fox youyou recovered some yuan power.


    She suddenly pointed to the direction of ten o''clock and said, "there... I feel that the fog there is thinner."


    Although he didn''t know whether it was dangerous or not, Su Chen couldn''t care so much at the moment. He walked around like a headless fly for a long time. Now he just wanted to find something.


    Immediately change the direction of the current and go downstream.


    After about five or six minutes, Su Chen suddenly fell down with the current.


    The fog dispersed, and Su Chen and Hu youyou fell into a narrow valley.


    The diameter of the deep valley is no more than 20 meters, but the depth is 500 or 600 meters. It looks ordinary, but the fog outside can''t flow in.


    Su Chen took out a handful of fluorite for lighting and scattered it into the deep valley, shining the small deep valley.


    "Lord Youyou, sit down and have a rest. Have something to eat. I''ll look around."


    Fox youyou sat down and nodded. The deep valley is not big. You can see the whole picture at a glance. There is no fog here. Don''t worry that they will disperse.


    But to be on the safe side, Su Chen still played a red divine pattern and wound it around himself and the fox youyou''s arm at the same time.


    "What is this?" asked the fox, looking curiously at the divine pattern on his wrist like a red rope.


    Su Chen smiled: "it''s called Qianli marriage. As long as you help this divine pattern, as long as you are within a thousand miles around me, I can accurately lock your position. You can''t escape if you want to escape."


    Fox youyou didn''t know that Su Chen was flirting with her again, but fox youyou didn''t have the strength to say anything more, so she had to follow him.


    Soon, Su Chen searched the inside and outside of the valley.


    Back to the fox youyou side, Su Chen shook his head: "I didn''t find anything except stone or stone."


    "At least there is a foothold. There is no mist here to absorb our strength. We can take this opportunity to recover."


    Su Chen nodded, took out a Guiyuan pill and swallowed it. At the same time, she stuffed several bottles of Guiyuan pill for Hu youyou.


    "Don''t you keep it?"


    Su Chen said, "there''s a lot, enough."


    Su Chen refined a lot of this recovery type of pill. He can''t use it at ordinary times, so he has a lot of reserves. There are hundreds of bottles of Guiyuan pill alone, ten pills in a bottle, which is enough to consume a long time.


    Sitting cross legged, Su Chen was not idle.


    "System, do you know where this is?"


    Unable to answer host question


    "Can you analyze the components of the fog?"


    "Insufficient system level."


    Su Chen was slightly stunned: "can you upgrade the system?"


    "After the host completes the task each time, the system will obtain a certain experience value. After accumulating enough experience value, it can be upgraded."


    "Wipe, and this setting?"


    Su Chen said in silence, "how much experience is the system to upgrade?"


    "The current experience value has reached two-thirds of the upgrade needs. The host can complete the task and help the system upgrade as soon as possible."


    Su Chen lost his temper as soon as he heard this: "I don''t want to do a task, but you can also release some normal tasks and become a third rate in the world. What do you want me to do?"


    The system was silent for a while and said, "all tasks are randomly generated, and the decision-making power of the system is limited."


    Even pass the buck!


    Su Chen thought for a moment and asked, "what new features will you have after you upgrade? It will take another year if you don''t upgrade."


    If so, Su Chen would rather not upgrade the system.


    System: "after the system is upgraded to version 0.2, the mall exchange function will be enabled. Skill points can be used as mall currency to buy props, and more new ways to obtain skill points will be released."


    Wipe, that sounds tempting!


    It seems that the task has really been done more.


    "How many versions of the system can you upgrade?" Su Chen asked again.


    System: "the system can be upgraded several times, which does not depend on the system itself, but on the growth potential of the host."


    "OK..."
