Therefore, in order to connect the data of the three circles in real time, a complete set of long-distance wireless networking equipment must be made in the design room again.


    Fortunately, this whole set of facilities is not particularly difficult, but it is slightly more than the technology on the earth''s side.


    After indexing all the atlas of the book of creation and Huang Si''s existing knowledge system, the retrieval speed of the automatic drawing instrument is greatly improved. The drawing of "ultra long distance wireless networking device" took only two days.


    Next, Huang Si stayed in the green world and spent months there to spread ultra long-distance wireless networking devices all over the world, even one on each of the two moons.


    Finally, there are servers and supercomputers. This is simpler. It can be done by using earth technology. After Huang Si assigned the task to Xiao Ke, he went back to the dark space alone.


    After arranging the family members and artificial intelligence, Huang Si came to the world before the fifth fragment, the secret world.


    The secret world is actually a huge treasure left by Gu Yan''s noumenon. It is not only as simple as 18 checkpoints. The facilities inside the checkpoint, the reserves outside the checkpoint, and many equipment in the core area have complex composition for research and learning.


    Even the whole secret world itself is a combination of the two laws of machinery and life.


    As long as Huang Si devotes himself to research, he can learn a lot of law knowledge. You can even input many non artifact items into the atlas one by one as a reference for the automatic drawing instrument.


    However, Huang Si didn''t come here to learn mechanical laws, but to find a reference for whether there is spatial law.


    In order to be efficient, Huang Si directly came to the core of the secret world. He is now the master of the world. Naturally, he can come at will and will not be suppressed by the ban on air.


    The core area of the secret world is a circular space surrounded by walls, and above it is the sky of the secret world. Naturally, the sky here is not very high, because there is no space here, and no one can go to heaven.


    Huang Si pressed his hand on an energy interface at the core of the secret world, and the creative power was transformed into original energy and poured into it. The essence of the secret world is a large mechanical structure, so its operation needs energy. Without energy, many functions will slowly stop.


    And the energy it can use is raw energy.


    As the Lord of the world, Huang Si can clearly see the route of energy flowing through.


    After the original energy flows into the core, it splits into nine branches and flows in different directions. After a set of complex conversion devices, some branch lines become electrical energy, others become thermal energy, some seem to be life energy, death energy, and even two unknown energies. The gray one flows part to the second level, which seems to be psionic? There is also a silver one. I went to the back several levels. I don''t know what it is.


    Gu Yan is right. You can learn a lot here.


    After losing energy for three days, Huang Si finally replenished the energy of the secret world. Its 18 levels, as well as many non level spaces and structures, also began to operate normally.


    Now, Huang Si can adjust the difficulty and operation mode of each level through the core, so that if the family members form a team to challenge the level, they don''t have to worry about the difficulty. But it''s not urgent to do this now.


    After solving the energy problem, Huang Si immediately began to check the storage of items in each area through the core.


    While checking, Huang Si began to enter the atlas in the secret world.


    This work is very hard, because he has never seen or heard of most of the items, and it is difficult to understand whether using the knowledge of the green world side or the earth side. Fortunately, careful analysis of these items can find traces of laws, so Huang Si has been analyzing them in the way of law research.


    When analyzing, if you encounter an incomprehensible law, you can compare it with the law field in your own world system to see which area can be touched and which law is contained.


    After complete analysis, it can be recorded in the book.


    Most of the things here are actually of low value, especially those piled up in the empty room outside the level, which is almost rubbish. Probably Gu Yan''s Noumenon was thrown here. However, Taobao can also be found in the garbage. Maybe you''ll find something of great value sometime.


    While learning, I looked for it. However, I searched directly here for a month, almost searched 20% of the rooms, and only 3 items related to the law of space were found. There are 2 items containing the law of time.


    But he can only distinguish it, but he can''t analyze it. Huang Si looked at the value of his space law, and there was no movement compared with a month ago. It''s worthy of being a superior law. It''s really difficult to learn and understand.


    One day, Huang Si came to a room that looked like a warehouse between the sixth and seventh levels.


    There are a lot of messy items piled up here. Huang Si roughly scanned several times with his consciousness to find out if there are items containing machinery or other laws.


    In the stack of items, five large and small objects were raised by him with mental strength. When Huang Si was ready to analyze and enter them, the remaining light from the corner of his eyes swept to a huge irregular cylinder in the corner of the stack of items.


    "Eh? Why didn''t I notice this when I was scanning?"


    Huang Si immediately scanned it again with his consciousness, but when his consciousness swept over the huge cylinder, the cylinder seemed to exist at all and was completely unaware of it.


    He immediately unfolded the mental force field, shrouded the cylinder and tried to lift it.


    But the mental force field just like can''t grasp this thing, directly leaked from it.


    A big thing that can be seen by the naked eye but can''t be grasped by mental force?


    Huang Si quickly flew to its side.


    The irregular cylinder lies obliquely in the corner of the room, more than a kilometer high; The length, from the part exposed outside the pile, is more than two kilometers.


    Other items can be grasped. Huang Si immediately grabbed all the garbage mountain like items and threw them aside. Then the irregular cylinder shows its true face.


    It is generally in the shape of a cylinder, but it is composed of stepped rings. The diameter of the circle in the middle is slightly thicker and the diameter of the two ends is slightly thinner. From the end facing Huang Si, its round surface is concave, and there is a structure that looks like a door valve.


    Around the round surface, there are some small inlays, like metal, but there are extremely serious corrosion traces. I don''t know what they are used for.


    This thing is like a water pipe valve.
