With Xiao Wei's research as a foundation, Fei Lienong agreed without hesitation about the research on the energy network on the planet that Li Yu mentioned next.

Fei Lienong can be said to be impatient for the study of biological genes. Fortunately, he also knew that this was not a temporary matter, so he discussed other research matters with Li Yu first.

Fei Lenon led Li Yu and the others to the center of the palace, a place like a stadium.

"Our way to preserve data is to use this kind of crystal." Fei Lienong directed his ministers to remove the cover from a huge pile of objects in the center of the palace, and a crystal mountain of flashing crystals appeared in front of Li Yu and the others.

The Purple Moon Kingdom is the official title of Fei Lenong and his country. This is not because Li Yu and his friends were not in place for their diplomatic etiquette. After coming to this planet, they were greeted by others for so long before they remembered to ask about the official title of civilization of the other party.

The understanding between Li Yu and the others and Fei Lenon can be said to be in a mess. When they met for the first time, Fei Lenon emphasized that this was the place under Ms. Sny, and said that the name of the planet under her feet was Vilotboon. So Li Yu thought that Fei Lenon and their country were called Vilotboon, and after all, they were also a global unified country, right?

Who knows that Felenon's kingdom really means that it is similar to the tribal alliance form in the primitive society on Earth.

"This is the copy of all the records in the history of our Ziyue Kingdom. You should study it first. If there is still need, the records that each subject has preserved in his hands. I can come forward to let you borrow them." Fei Lieong's words made Li Yu and the others know. It turned out that Fei Lieong's country was called Ziyue.

Li Yu and his friends looked at each other, and their embarrassed expressions flashed across their faces. Li Yu asked Fei Lenon: "Your Excellency, is the crystal you use natural or processed?"

Using crystal to save materials is a way that Li Yu did not expect. However, he did not expect that Li Yu could not do it, but he did not expect that Fei Lienong and others would use this method to save materials.

"This is a special item we discovered. It reacts extremely well to our spells. After special processing, the data can be preserved. Therefore, after the effect of this crystal ore was discovered more than 100,000 years ago, all our data preservation began to be used."

After all, it is the wizard civilization, which is different from the technological civilization of the earth. It is knotted and recorded, rock paintings, parchment, animal skins, bamboo slips, paper, and electronic storage equipment in modern society. I don’t know how many unrecorded civilization materials are there.

But Felennon and his friends solved all the problems with crystals.

The crystal mountain in front of Li Yu and his team is composed of pieces of crystals. Each piece of crystal is fifty centimeters long, twenty centimeters wide, two centimeters thick, and is translucent all over.

The history of the Purple Moon Kingdom is recorded for 100,000 years. Most of the previous history was told in words and can only be heard as stories or myths. After the record of the crystal, the Purple Moon Kingdom officially appeared as a historian, who specifically used it to record what happened in the Purple Moon Kingdom.

This kind of record covers most of the things that happened in the Purple Moon Kingdom, such as the invention of new spells, the salivation of new intelligent creatures, and the changes in biological races. It can be regarded as an encyclopedia.

After Fei Lienong's explanation, Li Yu found that this kind of recording crystal was very interesting.

"Li Yu, I thought that this kind of recording crystal was to directly use mental power to input and output information, but unexpectedly, they actually used spells." After learning the spell to read and record crystals given by Fei Lienong, Fang Qianmo unexpectedly said to Li Yu.

Lin Wanbai had already picked up a record crystal in his hand, and read the information inside and said, "That's Li Yu, it was too unexpected. However, this kind of record crystal is not far from the computers used on Earth now."

Compared with the computer on Earth? Li Yu shook his head and said, "This is incomparable. The functions of both are different. It can only be said that each has its own strengths."

"The functions of computers on Earth have evolved to this point, and countless additional functions have evolved from the initial simple calculation. However, the functions of this kind of recording crystal are just simple recording knowledge, which is a bit wasteful!"

Fang Qianmo agreed and said: "That's right, Fei Lienong can use this kind of recording crystal as the main source and invent a spell computer like an earth computer."

Li Yu did not pay attention to the records of the records in the crystal, but became interested in recording the crystal itself. Fei Lienong also prepared some extra blank recording crystals, and Li Yu took a blank recording crystal to study.

Sun Yixuan began to study and record the content of the crystal seeds under the guidance of Fei Lienong. Li Yu originally wanted her to slow down, but she could not wait until she developed the spell transformation equipment.

In Li Yu's view, these recording crystals are like books in libraries on Earth. Although they have a lot of knowledge, they are inconvenient to read. Li Yu wanted to develop a spell reading and conversion device to export the data in these recording crystals to the main computer of the space number, which makes it easy to study.

In Li Yu's opinion, this kind of spell reading and conversion device is not a big deal. Before this, what Li Yu had to do was to understand the storage principle of recording crystals.

Li Yu quickly developed the material of the crystal. It was an ordinary carbon-silicon composite crystal, which was doped with some metal crystals to form a crystal with a special structure. This crystal is extremely affinity for spells.

After processing, through spells, the recording crystal will form a storage unit inside to store spell information. To read the internal information, it can be done by reading spells.

The historians of the Purple Moon Kingdom are proficient in mastering these two spells, and their work efficiency is many times that of others. These two small spells are also spells that smart creatures in the Purple Moon Kingdom must learn. If they do not learn these two spells, their status will be similar to that of the illiterate Chinese.

Most of the information recorded in the crystal is three-dimensional. There is basically no storage medium similar to the earth's plane text, which means that the Purple Moon Kingdom basically does not have any rich text like the Earth. The Purple Moon Palace has text, and the text is also similar to graphic characters. However, due to its special magic civilization and the special way of composition of intelligent creatures, the text usage rate of the Purple Moon Kingdom is very low and there is almost no development.

If you have something to do, you can use your mental power to transmit the expressed information through spells. Compared with the text, you will not know where the efficiency is higher.

But Li Yu knew that the Purple Moon Kingdom probably underestimated the function of text. Recording crystals must be charged every once in a while, and it has a service life. When it expires, the record crystals must be replaced to save the information. This is a very troublesome thing.
