From this point of view, "micron-level size control" is used to build a civilization and build an army, and it is much more powerful than the legendary magic cheats such as Jiuyang Divine Skill, Jiuyin True Scripture, and Dugu Nine Swords combined.

In addition, the use of "micron-level size control" and a higher level of "nano-level size control" can improve a civilization's mechanical production ability to a very terrifying level, and can also use this ability to make many high-precision instruments, make a deeper understanding of the natural world, and finally achieve the purpose of recognizing and exploring the high-dimensional world, and promote to a high-dimensional civilization.

According to the high-dimensional explanation, this is the dimension lock:

The gene lock emphasizes the sublimation of individuals between life and death, breaking the limitations of their own genes and promoting to higher dimensions;

The dimensional lock improves the evolution of the entire civilization, studies and cognition of the high-dimensional world from the perspective of knowledge, and finally promotes to the high-dimensional civilization, which should be said to be the promotion path of the scholar.

If the blood nerve is the secret book of the martial artist, it is the guardian of civilization and the road of gene lock, and the "micron-level size control" is the secret book of the scientist's magic skill, and it is the road of civilization instructor and dimensional lock.

Zhao Dagui will advance in the future, not only to pay attention to the evolution of personal strength, but also to pay attention to the improvement of civilization, and not to abandon one side.

The ability of the "Main God Library" to collect book secrets, as well as the use of spiritual gold, etc., are very suitable for the path of dimensional locks;

Moreover, according to the principle that the main god must produce a good product, it also has a strong auxiliary function for the path of gene lock, and it is definitely a very cool thing to use well.

(Note: So, book lovers should read patiently, this book will get better and better; in addition, the advanced path of gene locks and dimension locks will be described step by step in the later plots)

Today's first practical pistol and the first practical spear are very commemorative, Zhao Dagui carefully read the two design drawings, and then there are these two more design drawings in the main god library--- this is the most original ability of the main god library, you can collect the books and materials that the main god sees, and store them in the library.

With these design drawings for reference, Zhao Dagui can make these two guns directly in the main god space, without producing them one by one, which is a bit like the "drawings" that are often said in video games in the modern world to make weapons.

The next thing to do is to make the "micron-level size control" ability into a skill book that can be stored in the library.

The foundation of "micron-level size control" lies in the main god space, spiritual gold, and the "Introduction to Mechanical Drawings" book.

Zhao Dagui has read the book "Introduction to Mechanical Drawings" several times, and there is also this book in the library, and at this time it is necessary to make some modifications, add and make "absolute straight line" and "absolute circle", combined with "brass ruler" and "spiral micrometer", to obtain the process of micron size.

Zhao Dagui took out about a kilogram of spiritual gold in the main god space, and as soon as his heart moved, this spiritual gold became more than fifty gold plates the size of ordinary books, and then the content of the new version of "Introduction to Mechanical Drawing" and the Euclidean geometry knowledge and spiral micrometer principle needed to make "absolute circle" appeared;

Of course, the characters and drawings of this Lingjin book are all highlighted from the gold plate, just like the relief, more like a book formed by the integration of more than fifty gold plate reliefs.

The content of this book is no longer limited to "Introduction to Mechanical Drawings", so Zhao Dagui changed the title of this book to "A Preliminary Study of Micron-level Dimensional Control".

The main god library has the ability to extract the memories on the books and form extraordinary books, and Zhao Dagui used this ability on this "micron-level size control", and there was a light that enveloped Zhao Dagui and this book, extracting Zhao Dagui's remaining spiritual imprints and memories on this book.

Then on the cover of this book, there is an additional light curtain the size of a mobile phone screen, on which a video of Zhao Dagui learning "Introduction to Mechanical Drawings" and using Lingjin to obtain "micron-level size control" ability.

Zhao Dagui clicked on the light curtain, and found that he found that the process of learning mechanical drawing and fiddling with the spiral micrometer in the main god space and other memories were replayed, and he could experience the whole process immersively, until finally the size of the spirit gold was controlled to the micron level, and the micron-level size control ability was obtained.

The function of this book is simple and practical, if a high-dimensional being obtains this "micron-level size control", it can experience the above experience of Zhao Dagui, and then obtain a similar "micron-level size control" ability to Zhao Dagui.

This is like a skill book in an online game, you can get a certain basic ability of an engineer with a pat of your hand, and if Zhao Dagui learns other internal strength cheats and sword cheats, it can also form a similar skill book, so that those who get it don't need to practice hard by themselves, and can also get relevant cultivation experience.

The "Blood Nerve" in the "Library" is the skill book of the martial artist, and the "Preliminary Study of Micron-level Size Control" is the skill book of mechanical engineering.

In other words, the so-called transcendent books, from their nature to how to use them, are very similar to the skill books in online games.

Normally, in order to form a transcendent book, it requires a monk with very high cultivation and spiritual power to read a certain book repeatedly, and in the process unconsciously form a spiritual imprint, Zhao Dagui did not reach this level.

However, after all, he is the master of the "Lord God Library", and he directly uses spirit gold to form books in his main god space, and he can extract his own memories to form this kind of transcendent books, but this also has to abide by certain rules and be subject to various restrictions.

The next thing is very simple, Zhao Dagui just exchanged a large amount of gold in Hong Kong some time ago, and he actually has more than 10,000 taels of gold in his hand, which is just enough to build a divine building.

The divine building that Zhao Dagui has always wanted to build the most is the "Exchange", so he took the design drawings of the "Exchange" outside the library and found a place to sacrifice 10,000 taels of spiritual gold to build this divine building that he had always wanted to build.

The function of the "exchange" is as its name suggests, which is used to trade items with people, and those who can use the exchange to trade are naturally not ordinary people, at least like Zhao Dagui, who is building an exchange in the high-dimensional world.

Zhao Dagui is just the lucky one who accidentally got the inheritance of the previous main god, in fact, he is the poorest and weakest kind, and other high-dimensional existences must be much richer and stronger than Zhao Dagui, as long as they are operated properly, they can exchange a lot of good things.

The "Exchange" is also a beautiful gold building, and when you enter the exchange after it is completed, you will find that there is an additional light curtain inside, on which there are many images of other exchanges and the items they sell, as well as items that the owners of other exchanges want to obtain, etc., and you can also leave a message, which is very similar to a certain treasure or a certain cat.

Zhao Dagui doubled, and knew that he wanted to take the traded items to the exchange, and then marked the number and type of items to be exchanged on the light curtain.

However, Zhao Dagui currently has not many items that can be exchanged for benefits, and only two transcendent books can be used reluctantly, so he took out the two books of "Blood Nerve" and "Micron-level Size Control", and used the ability of the main god library to copy one copy of both books and put them in the "exchange" for trading.

You can write what you want to get on the remarks in the trading column of the "exchange", and Zhao Dagui writes:

"Blood Nerve, exchange for 20 Dao coins, micron size control, exchange for 10 Dao coins

Note: You can also use Blood Dao Spirit Stones or Blood Dao Cultivation Materials instead of Dao Coins, and one Blood Dao Spirit Stone can be exchanged for two Dao Coins."

Spirit stones are a resource that cultivators value very much, and they contain a large amount of innate true qi, which can be directly devoured by cultivators to increase their own cultivation.

There are a total of 3,000 Great Dao in this world, and there are 3,000 different innate Dao True Qi, such as the Blood Dao, the Sword Dao, the Fire Dao, and the Water Dao.

Zhao Dagui's cultivation of the blood nerve is considered a blood path, so he needs a blood path spirit stone, and the red beads obtained by slashing the power infiltrated by the demon god before are considered blood path spirit stones;

The cyan beads obtained by killing the creatures formed by the Heavenly Thunder are the Thunder Dao Spirit Stones, which should be easy to understand for book lovers who have read countless online novels in these aspects.

The cultivation path of each monk is different, so that the existence of the cultivation of the Five Elements Dao can obtain the Blood Dao Spirit Stone, or the Blood Dao cultivator can obtain the Thunder Dao Spirit Stone, there is an embarrassment that it cannot be used directly, and it has to go through some transformation before it can be used, at this time, a spirit stone that has no attribute and is suitable for all Dao type monks is needed.

The so-called Dao Coin is this kind of non-attribute spirit stone, which is made by real high-dimensional power, the advantage is that it is suitable for all types of monks, and the disadvantage is that monks who practice a certain path may prefer to obtain the attribute spirit stone of the avenue to which they belong.

In any case, whether it was obtaining the Blood Dao Spirit Stone or the Dao Coin without attributes, it could greatly speed up Zhao Dagui's cultivation speed.
