Writing a letter of introduction and throwing it to Fielding, Jiang Feng took out a bag of silver coins from the space ring and threw it to him.

"Take the money and pack it up for yourself, and then take the letter to the palace and castle, and give it to the guard at the gate, and tell him that you are a servant of the wizard, and let him take the letter to a butler named Grede. After reading the letter, Greid will naturally arrange your accommodation. ”

"The king, the palace?" Fielding was surprised.

"Yes, I'll be staying there for the time being, but I'll be leaving Walland soon and going to Sardinia." Looking at Fielding, Jiang Feng continued, "So you'd better buy something that you will need when you go far away, there is not much time left for you to prepare." ”

"Sardiniburg?" A shocked expression appeared on Fielding's face, and he looked at Jiang Feng in disbelief, "Are you preparing to fight for His Majesty the King?" ”

"I don't have this plan for the time being, I'm just entrusted by someone to send something over."

Jiang Feng didn't elaborate on his purpose, and after noticing this, Fielding didn't ask any more questions with great interest.

After saying goodbye to Jiang Feng, he first went to the port area, found a cheap hotel to live in, and then went to the nearby market to buy the things he needed for fulfillment.

As for Jiang Feng's side, after dealing with Fielding, he turned around and returned to the Alchemist Guild.

Located on the east side of the Alchemists' Guild, the library is a circular building covering an area of several thousand square meters, about the height of a three-story building. After entering the venue, even the floor is polished with marble, which shows how rich these alchemists are.

Sitting behind the counter in the lobby was a young woman with short brown hair and a little freckle on her nose, and her first impression was that she had large breasts and was enthusiastic about her work.

After paying a hundred UBS at the counter at the entrance of the library, Jiang Feng followed the steps of the old man in front of him and went through the registration procedures for entering the library. When she saw that Jiang Feng was about to enter the library empty-handed, the young lady who was sitting at the counter showed a surprised expression.

"Are you going to go in like that?"

"Or else?"

"It's probably your first time here, haven't you noticed that you're missing something?"

Following her line of sight, Jiang Feng noticed that most of the other people who had registered to enter the museum were holding parchment and quills in their hands.

Knowing her kind reminder, Jiang Feng smiled, shook his head and said, "I don't need those things." ”

With that, he walked towards the library.

……

To use an inappropriate analogy, if Baron Fred's book collection is compared to a mouse, then King Walland's book collection is an elephant.

As for here, Jiang Feng seemed to have seen a zoo.

Rows of bookshelves are like dominoes, arranged in the circular hall.

Every 10 steps, there is a wooden table for the use of the museum staff. Most of the people who come here to read books carry parchment and quills, and while reading voraciously, they are diligently extracting passages from the book and making notes.

After all, the price of coming here to read is not cheap, and ten silver coins can buy an hour of reading time. For the citizens of Valland, this is equivalent to two days' food rations for most families. And in order for their children to pass the entrance test of the association's mentor and have a chance to become a formal alchemy apprentice, even a wealthy petty bourgeois family has to tighten their belts to live.

In this era without the printing press, the value of knowledge is so precious.

Seeing this scene, Jiang Feng also understood why Vallan's Alchemist Association was so rich.

For a whole day, Jiang Feng stayed here, and when he put down the last book, the books in the library on the first floor had already been turned over by him. With just one glance on each page, the text will be automatically entered into the database and sorted into categories.

The speed of turning books like a windmill made many members and apprentices who were struggling to write at the table can't help but look sideways, asking whether this guy is here to take notes or to make trouble.

"The amount of text with content is only about 10 million lines, which is less than expected."

"Many of the techniques described in papers and books are repeated research on the same topic. Although the phenomenon is studied, the essence behind it is not dissected through the phenomenon. It is no wonder that after 2,000 years, these natives have not yet come out of the Middle Ages. ”

The knowledge is miscellaneous but not precise, repetitive and redundant.

The most fatal thing is that because of the distractions of witchcraft, spiritual energy, and even belief in gods, alchemists have directly crossed the study of natural sciences and gone further and further down the path of empirical science.

As a very simple example, a research book on alchemy in the engineering department mentions a design method of designing trebuchets to maximize the power of loading and firing, but the author himself is not aware that he has applied the principles of axles and levers in his design.

If you can summarize these things, you can use them in more than just trebuchets.

However, having said that, for Jiang Feng himself, the gains during the day were still quite large, especially in the two fields of potions and enchantments, and he had a fairly deep understanding of the basic principles of inscription and rune technology.

And these basic things are all things that Captain Monkyrie's notes have not even mentioned.

As agreed, Old John arrived at the door of the Alchemists' Guild in the evening in a carriage.

Many apprentices, even ordinary members who had not yet become apprentices, were so surprised that they almost dropped their eyes when they saw him sit in the royal carriage. No one expected that this strange person who flipped books like a windmill would be a guest of honor of the royal family......

After returning to the castle, Jiang Feng met Leia in a cloak at the door.

It seemed that he had been looking for himself for a long time, and as soon as they met, Leia walked over to him.

"Where have you been? How come I haven't seen you all day. ”

"Wander around casually outside," Jiang Feng smiled and teased in a relaxed tone, "Why, you miss me like this if you haven't seen me for a day?" ”

Ignoring Jiang Feng's ridicule, Leia asked.

"How long are you going to stay here?"

"It depends on how well your body is recovering, although you still have to cross a few forests and hills from Warland to the plains of Sardinia all the way." Jiang Feng shrugged his shoulders, "The conditions on the front line are not as good as here. ”

"My body is fine. We could not wait any longer, and in the afternoon I went to a tavern in the port area, where I learned that the situation at the front was not optimistic. I don't want a corpse waiting for us when we send the sword over. Leia said in a serious tone.

“…… If you're okay, we can leave the day after tomorrow at the earliest. ”

Although she could see that she was being reckless, Jiang Feng didn't say much.

Leia was exactly what he was worried about.

It was at the forefront of the kingdom's war against the rebels.

And on the battlefield, even a master knight cannot guarantee that he will survive 100%.
