The only material the Tang Chamber of Commerce lacks is the Yuan Neng Crystal.
Yuan energy crystal is a natural crystal stone that can absorb and store energy.
This kind of crystal is an indispensable core part of the Yuan Yuan inscription pattern, and it is also a necessary material for making the Yuan Yuan inscription pattern.
Not only the Yuan Yuan inscriptions, but also many high-level inscriptions in the Divine Realm are made of this kind of crystal stone.
The conditions for the formation of Yuan Neng Crystal are very harsh. The geological conditions of the Tianwu Continent are very difficult to form. I am afraid that this kind of crystal will not exist. Only the God's Domain with rich resources can produce this kind of crystal.
As the president of the Tang Chamber of Commerce, Tang Shi'an has been in business for many years and has traveled all over the country, but he has never even heard of Yuan Neng Crystal.
This is enough to show that the probability of Yuan Energy Crystal existing in Tianwu Continent is very low. At least in a small country like Nanxia Kingdom, it is impossible to exist.
Without the Yuan Energy Crystal, it does not mean that it is impossible to create the Yuan Energy Inscription Pattern.
As long as you find suitable energy storage materials, you can also replace Yuan Neng crystals to make inferior energy storage inscriptions, but the effect may not be as good as those made from Yuan Neng crystals.
However, Lin Yun has no way to be picky now. After all, he is in this small kingdom with limited resources. He can only make do with low-quality Yuan-storing inscriptions for now. After finding the Yuan-energy crystal, he can re-make high-quality Yuan-storing inscriptions.
Carry out engraving.
But what materials should be found to replace Yuaneng crystal? This is a problem.
Lin Yun was in the God's Domain in his previous life and did not know much about the situation in Tianwu Continent. He did not know what materials Tianwu Continent had that could be used to replace the Yuan Energy Crystal.
After asking Tang Shi'an for a long time, Tang Shi'an couldn't give an answer.
Even the well-informed Tang Shi'an didn't know this kind of thing, let alone the ignorant idiots below.
Therefore, Lin Yun could only leave the Tang Chamber of Commerce with the materials and return to Yuzhou Wufu.
Lin Yun just heard not long ago that the library of Yuzhou Wu Mansion contains a large number of books, spanning various fields, covering ancient and modern times, and covering everything.
Among so many books, it might be possible to find materials that can replace the energy crystal.
With this idea in mind, Lin Yun quickly came to the library.
When Lin Yun arrived at the Library Pavilion, the sun had already set and the whole world was shrouded in night.
Seeing that no one was guarding the library and the door was unlocked, Lin Yun directly opened the door and entered.
The interior space of the library is large, but it is filled with wooden shelves for storing books, which makes it look a bit crowded.
Perhaps because it was getting late, the entire library was deserted, except for a young man with a sinister eyebrow, lying on the second window sill, looking out.
The young man looked out of the window as if fascinated, his face was intoxicated, saliva was dripping from the corner of his mouth, and he didn't know what he was looking at.
When he heard Lin Yun's footsteps, he suddenly retracted and hid under the bookshelf, panicking as if he had done something wrong.
Lin Yun had no interest in what this young man was doing or why he was exclaiming like this.
After entering the library, Lin Yun shuttled among the rows of bookshelves, patiently flipping through various books.
Lin Yun's mental strength is far beyond that of ordinary people, so he reads very quickly, flipping through more than a dozen thick books in a blink of an eye.
Soon, Lin Yun found a book about inscription patterns.
This book records various knowledge about inscription patterns, and also introduces various inscription pattern materials in Tianwu Continent in detail.
This was exactly the book Lin Yun was looking for on this trip. Lin Yun immediately opened the book and began to read it carefully.
While he was looking at it in awe, the door to the library was violently pushed open, and a red-haired girl rushed in angrily.
"You peeping tom, have you had enough of hiding in the library? Get out of here!"
A sharp and arrogant female voice sounded.
A red-haired girl appeared at the end of the bookshelf and rushed towards Lin Yun angrily.
This red-haired girl is about seventeen years old. She wears a tight leather jacket that highlights her hot figure and her sexy waist, giving people a very cool feeling.
As soon as she rushed up, she punched Lin Yun unceremoniously.
Lin Yun's eyes were still focused on the open book, without even glancing at the fist that was thrown at him.
Just when the red-haired girl thought her punch was about to succeed, Lin Yun's head just tilted slightly.
That seemingly random deflection was just the right amount of time to avoid the red-haired girl's fist.
The red-haired girl's punch missed, a flash of surprise flashed in her eyes, and then she punched several times in succession and kicked Lin Yun's lower body savagely.
Even though the red-haired girl's movements were skillful and coherent, and her angles were tricky and ruthless, she was still avoided by Lin Yun accurately, and no punch landed on Lin Yun.
When she punched Lin Yun for the last time, Lin Yun dodged sideways. While avoiding the fist, he reached out and grabbed the red-haired girl's arm and pulled her back.
The red-haired girl immediately lost her balance, flew forward uncontrollably, and hit the bookshelf, knocking the entire bookshelf over.
A large number of books scattered down, covering the red-haired girl, covering the entire floor.
But Lin Yun seemed as if nothing had happened. He still stood there calmly and continued to read the books in his hand as if nothing had happened.
"Little Pepper, how is the situation here?"
"Did you catch that peeping tom?"
"We're all here to help!"
At this moment, several soft female voices sounded.
Immediately afterwards, several girls rushed into the library one after another, appeared in front of Lin Yun, and blocked Lin Yun's front, rear, and left paths.
The red-haired girl also stood up from the pile of books and looked at Lin Yun with an angry face.
Although the expression on her face looked angrier than before, she did not continue to rush forward and attack Lin Yun.
Because in just that brief moment of fighting, it discovered the extraordinary strength of the young man in front of it.
Although her strength ranking in the outer sect is not high, in terms of reaction speed, she is definitely among the best.
However, even with her fierce offensive, the young man in front of her could easily avoid it, and even showed a nonchalant attitude.
Absolutely no one among the outer sect can do this!
Could it be that this young man is an inner disciple?
But the inner disciples are usually eighteen or nineteen years old, and this young man looks like he is only fifteen or sixteen years old.
If he is really an inner disciple, then he is too young, right?
Thinking of this, the red-haired girl also calmed down, suppressed the anger in her heart and said to Lin Yun: "How did you get in?"
Lin Yun did not speak, but concentrated on reading a few lines of text in the book.
Because what these lines of text describe is a type of inscription material called "energy storage ore".
The purpose of this material is very similar to that of Yuan Neng Crystal. Although its power is not as powerful as Yuan Neng Crystal, it can also be used to make Yuan Neng Crystal in place of Yuan Neng Crystal.
