There are two libraries in the imperial capital of Zion, one is the Royal Library of Samuel in Uptown and the Library of Ogmar next to Ogma College in Midtown. The former is only open to members of the upper royal family, nobles, residents of the upper city, and some magicians and alchemists with special qualifications, in short, without special status, the library guarded by royal guards cannot be entered at all. The latter, on the other hand, is fully open, and anyone can read it, except for those who can't borrow books and take them with them.

Of course, Xu Zheng scoffed at the former's hierarchical approach, but he had a good impression of the latter, so he chose the latter without hesitation and went straight away.

The Ogma Comprehensive Academy and the Ogma Library, which were next to each other, were both famous in the imperial capital of Zion, and it was not a hassle to ask for directions, and Xu Zheng quickly found them.

When passing by Ogma Comprehensive College, Xu Zheng looked at the students inside through the wooden fence, and couldn't help but recall his short study career in his previous life. Summing up those days, it felt like a dragonfly touching water, flying by in an instant, leaving little impress. Now recalling the scene of that day like the wind passing without a trace, and then looking at the students in Ogma Comprehensive College running and playing freely, Xu Zheng can't help but be envious, I really hope that one day I can return to the school, experience the warm campus life again, and make up for the study era that he did not have any memories in his previous life.

Xu Zheng stood outside the fence and looked at it for a long time, and his thoughts were surging, and he seemed to be stupid. It wasn't until the students in the fence turned their heads to look at him with strange eyes that Xu Zheng came to his senses, smiled embarrassedly, and turned around and went to the library.

As soon as I entered the library, the scene in front of me was indeed as Xu Zheng expected, there were really a lot of people. Walking to a place that looked like the main station, an old man like an aunt looked up at Xu Zheng and asked, "What kind of book do you want to read?" The young man in front of him had black hair, black eyebrows and black eyes, and his appearance was very unique, and the old aunt couldn't help but look at him a few more times.

Xu Zheng scratched his scalp for a while, feeling that this question was not easy to answer. After thinking about it, he said, "Is there anything related to magic?" I want to know about it. ”

Looking at Xu Zheng for a long time, looking at Xu Zheng's dress as a resident of Xiacheng District, the old aunt shook her head helplessly, another teenager who was poisoned by magic, always thinking about learning advanced magic, and one day becoming a magician and becoming famous. If everyone were so easy to become a magician, there would be less so many magicians. Boys, they all love to have unrealistic and gorgeous dreams. Although he thought so in his heart, he didn't want to pour cold water on these teenagers who worked hard to weave their dreams, so he only smiled mildly and said, "If you go through the passages in the bookshelves on both sides, you will see a staircase, which goes directly to the fourth floor, where there are all books related to magic and magic arrays. But-" smiled kindly, and said, "I suggest that you go to the first floor and take a look at the origin of magic and its general outline, and there are also some books on the introduction of magic arrays, which are more useful for those who are new to it." Then, the bookshelf goes to the end, turn right, go straight, turn right again, and you will see a small row of bookshelves, I can't remember the specific location. Find out for yourself. ”

Xu Zheng smiled and thanked the kind-looking old man and walked in the direction she pointed.

When I got to the ground, I saw a row of small bookshelves, and a small table was placed in front of the bookshelf that could sit around four people. There are many people in the hall on the first floor of the entire library, but this row of small bookshelves seems to be a lot deserted, and there is only one old man sitting at the table, and now there is Xu Zheng.

Xu Zheng climbed the wooden ladder on the small bookshelf, searched along the small bookshelf for a long time, and then found the origin of the magic, then took the book to the table and sat down.

The sound of pulling open the table and chair alarmed the old man who was reading the book, and the old man looked up at him and was also stunned when he saw Xu Zheng's distinctive black hair, black eyebrows and black eyes.

Xu Zheng whispered apologetically: "I'm sorry." ”

The old man smiled, and his eyes turned around Xu Zheng's distinctive eyebrows before returning his attention to the book.

Xu Zheng sat down and did not open the book immediately, but thought about making ice.

In this other world, Xu Zheng summed up the methods, with what he has learned and his abilities, there are about four ways. The first is to use all kinds of knowledge learned in the previous life to make ice through physical methods, but in doing so, many details will be encountered. As far as Xu Zheng can see, the application of physical knowledge can be said to be extremely inextensive. To give a simple example, such as the sightseeing carriage of Hughes, even the basic damping device is poor, let alone the others. In addition, the idea that the two dwarves are missing and want to use their craft to build a pressurized device to reduce the temperature and make ice by pressurizing the liquefied gas, dissipating the heat, and then absorbing a large amount of heat when the liquefied gas is converted into air temperature. I believe that even if Xu Zheng can design the prototype of the entire set of equipment and draw it on the drawings, except for the craftsmanship of the dwarves, no one may be able to create it. And to be honest, for the fineness and craftsmanship requirements of this set of equipment, Xu Zheng is worried that even a dwarven craftsman may not be able to make it. So, this method is impractical, give up.

The second is to use chemical methods, through the deployment of various chemical reagents, to produce chemical should absorb heat to achieve the purpose of ice making. As far as Xu Zheng has learned, there are many chemicals, such as ammonia-containing and salt-containing complexes, which can be achieved through chemical reactions. But then the question is, where to find these chemicals? To produce these complex compounds from the most basic chemical elements? Xu Zheng doesn't have that ability. Not to mention where to find these basic elements, even if they do, how to purify and parse them is a problem. It's not like in the previous life, you could go to a chemical pharmacy or a lab and buy baking soda or polyammonia compounds directly from the clerk. Therefore, this method can also be abandoned.

After removing these two methods, which were difficult to achieve for objective reasons, Xu Zheng could only put his mind on the Heavenly Dao techniques he practiced and the magic that he had only heard of when he came to this other world.

The Heavenly Dao Technique can indeed be used to make ice. When the realm reaches the fifth layer, you can practice all kinds of secret techniques related to the Xuanbing technique in the Eastern Secret Arts, including methods for cooling, ice making, and the use of deep ice refiners. For example, in order to create a good low-temperature environment for himself, the basic spell Ice Trick can play a role in cooling down and making ice. However, in this way, trouble came again, Xu Zheng's Heavenly Dao technique was only now cultivated to the stable stage of the first layer, although he had never stopped practicing, but the entry realm had been frozen there, and there was no hope of breaking through. Once this Heavenly Dao technique has stepped into the first layer, it will no longer be possible to accumulate qi and jump from quantitative to qualitative changes as it did when he entered. Every time it advances, it requires not only a certain amount of accumulation, but also a mental understanding and an opportunity to break through. The accumulation is not difficult, but the two things of the heart's enlightenment and opportunity, one is mysterious and the other is unavoidable, so Xu Zheng is stuck in the third layer and has not broken through. Is it like when he crossed the level to open up his personal space and build a gathering spirit array in the vast forest sea, and forced himself to go beyond the level and do it brutally? Xu Zheng thought about it for a long time, but he still didn't have the courage to do it again. After the chaos, the regression of the realm is still a trivial matter, in case the fire aura rages and summons a great trick of the Frost Heavenly Arrival, then it will be a big disaster.

So the last hope can only be pinned on this expensive magic that does not know whether it is reliable or unreliable.

Thinking of this, Xu Zheng opened the magic origin. Half an hour has passed since I sat down and opened the book. During this time, Xu Zheng had been closing his eyes and pondering, and his unusual movements attracted the attention of the old man opposite, and he couldn't help but raise his head and look deeply at this strange young man a few times.

In fact, the old man had already noticed this young man. When he walked out of the gate of the Ogma Comprehensive Academy, he saw this young man standing outside the fence outside the academy, looking inside in a daze, the expression on his face was a little sad, a little confused, some longing, and even yearning, all kinds of complex emotions appeared on his face together, one moment he behaved like a sunny boy, and the other he behaved like a dying old man, which had already attracted the attention of the old man. This will see that when he got the book, he did not rush to read it at first, but closed his eyes and pondered for a long time, as if he had encountered some problem, which made the old man even more interested in him. I don't know why, the old man always felt that this boy was very different from other teenagers of the same age that Pingjue saw, not only because of his distinctive eyebrows, eyes and hair color. This young man has a very special temperament, like a faintly glowing luminous body, which will be missed without paying attention, but when you look closely, you will find that he is attractive enough to fully attract the attention of those around him.

Xu Zheng didn't notice that the old man was observing him, reached out and opened the book, and began to read it intently.
