Burying this doubt in his heart, Xia Lin didn't think too much about such indifferent things, so he set off to the Royal Academy of Magic to prepare to go to the royal library there for a while, to see if he could find some ideas for switching runes from there.

At the same time, he was also going to browse the spell models of the three-ring spells included in the Royal Library to see if he could improve his mage strength a little more.

After the fierce battle last time and the accumulation of meditation night after night during this time, Xia Lin felt that his spiritual power and self-physical magic power had increased to a considerable level, at least about two to three times that of when he first broke through to the second ring.

After using the slightly improved mental power meter and magic power meter to measure, Xia Lin obtained that his mental power value had reached 1980 meters, and his own demon power had reached 132 blocks.

took out the two data recorded when he just broke through to the second ring and compared it, at that time, Xia Lin's mental power value was still 780 meters, and his autologous magic power was 52 grids.

The average mental power consumption of the first ring spell is 50 meters, and the self-body mana consumption is almost 3.3 squares, and the average mental power consumption of the second-ring spell is 100 meters, and the self-body mana consumption is 7 squares, which is almost twice that of the first-ring spell, and if calculated according to this value, his current 1980 meters of spiritual power is enough to bear the need to break through to the three-ring mage.

It's just that Dean Manan said that there are some small differences between the three-ring spell and the two-ring spell, so it is more difficult for the mages to break through to the third ring, and Xia Lin's trip is to find out the difference between the three-ring spell and the two-ring spell.

Arriving at the Royal Library in the Red Palace of the Royal Academy of Magic, behind the tall information desk at the entrance is a quiet girl who is sitting on a high stool and looking through the books in her hand.

Judging from her somewhat immature face, she should not be more than twenty years old, but according to Xia Lin's understanding, the librarians of the Royal Library should be professors in the academy on rotation, so he ignored the young appearance of the librarian, adopted a polite attitude, and stepped forward to press the metal bell placed on the counter:

"Hello, Professor, I want to go to the library to look up some materials, here's my admission voucher!"

"Well, let me see ......."

The "girl" who was reminded by the bell calmly sandwiched a maple leaf bookmark in the thick black book, and then turned around and picked up the royal mage badge given to him by Dean Manan that Xia Lin placed on the table, and inadvertently leaned out her spiritual power to probe the fluctuations of spiritual power in the badge, and her young and beautiful face suddenly showed a little surprise:

"This is Dean Manan's Royal Mage Badge? Are you the same Charlene Karl?"

"Well, if it's the Charlene Karl of Runes & Magic, I'm right!"

Xia Lin nodded and replied.

"It's really strange, I heard that Charlene Carr was a graduate of our academy last year, and I still didn't believe it, but I didn't expect this news to be true...... By the way, I'm Mavis Duliwen, a professor in the Potions Department, and it's a pleasure to meet you, Mage Charin!

Since you hold the badge of Dean Manan, the Royal Library will not put any obstacles in your way, you can stay in it for as long as you want, and the *** area will be open to you.

But you still seem to be a second-ring mage, right? For your safety, I think you should be cautious about reading the books in the *** section, many of which have dangerous curse powers attached to them!"

Professor Mavis looked Xia Lin up and down for a while with the eyes of a strange creature, took out a thick and old book from the side, and while explaining the matters that Xia Lin needed to pay attention to, she wrote on it with a dipping pen, and finally she tore off a long strip of parchment from the book and handed it to Xia Lin:

"This is your *** area entry permit, remember to wait and leave your mental power mark on it, don't lose it, you can't enter *** area without this note!"

"I'm glad to meet you, Professor Mavis! So I'm going to look up some of the information I need!"

It was the first time that Charlin had come to the Royal Library, and he took it

This note, which left his own spiritual power mark on it, said goodbye to Professor Mavis. Xia Lin was already very curious about Potions, a course he had not experienced in the Academy, and now that he had the opportunity to meet a professor in the Potions Department, he naturally tried to have a good relationship with her.

"Well, there you go! If you need anything else, you can come to me at the counter, I'm the librarian of the Royal Library for the rest of the year!"

Professor Mavis smiled kindly at Xia Lin and picked up the thick book he had been reading.

Stepping into the Royal Library, a towering and vast space immediately comes into view, this was originally the banquet hall where Empress Lillian held a banquet, after the summer palace became the Royal Academy of Magic, it was transformed into the Royal Library by a famous architect, so this space has quite sufficient height, more than 20 meters above the ground under the dome of stained glass inlaid with rows of tall bookshelves, on these black sandalwood shelves are placed countless parchment books.

In addition to magic-related books, literature, history, architecture, military, politics, art, poetry, epic stories, folklore tales, geography, mathematics and other books that have been handed down in the Sassen Empire for hundreds of years are also piled up in it.

Arriving in the magical area, Xia Lin began to search for the books he wanted from the shelves, the royal library is usually closed to the public, but members of the royal family or some scholars with the permission of the royal family can still enter this temple of knowledge, in order to facilitate these ordinary people who visit, the library shelves are placed next to the tall wooden ladder.

As a mage, Xia Lin naturally didn't need to take such a painstaking effort to carry and climb these wooden ladders, he chose to use the mage's hand to directly select and remove the books he wanted from the shelves.

"Oldlan Spell Notes: Mage's Hand", "Manartok Spell Notes: Fireball", "Johnson Spell Notes: From Feather Fall to Levitation", "Rad Spell Notes: Fire Rune Research", "Introduction to Illusion Magic", "Spell Analysis: Armand's Serpent", "Spell Analysis: Secondary Phantoms", ......

The titles of the books on the shelves vary according to the age in which they were written, such as the older books from the era when the four major spell systems had not yet been established, and they were usually rewritten based on the spell research notes handed down by a certain mage.

After the establishment of the four spell systems, the names of the books often have a strong spell system color, even if they are not indicated in the name, the four spell systems and spell rings can be seen on the spine or cover page.
