When I woke up, I entered Terraria?!

"Books play an indispensable role in history. They record the wisdom and experience of our ancestors, enrich people's cultural heritage, and lay a foundation for inheritance for future generations."

Qi Yu walked in the corridor of the library, feeling the furry carpet under his feet, looking at the paintings hanging on the walls, and the warm lights like campfires above his head.

It instantly reminded him of the words his teacher used to repeat every day when he was a student, and he had scoffed at them at the time.

Unexpectedly, after traveling to another world, I still have to go to school and study.

Qi Yu sighed and pushed open the door to the library.

As soon as he opened the door, Qi Yu was stunned, because what came into his eyes was a spiral tower-shaped hall that was ten thousand meters high. He didn't know whether some magic or technology was used, but the interior of this library was far from as small as it looked from the outside.

Looking up from the hall, each floor is filled with huge bookshelves, which are densely packed with all kinds of books.

Sitting in the middle of the hall was a guide wearing a teacher's robe. She had short black hair and wore gold-rimmed glasses. She was holding a thick book and reading with her head down.

Around the hall, there are also many library staff and "worker" apprentices, cleaning the surrounding area and arranging bookshelves.

Qi Yu retracted his dazzled gaze and walked slowly towards the guide teacher, because he felt that it was too difficult for him to find the book he wanted from among all the thousands of books.

The guide was sitting at her seat and flipping through a book when suddenly a dark shadow appeared on the pages of her book, blocking the light above her head.

The guide frowned slightly, raised his head, adjusted his glasses, and looked at the person standing in front of him. Seeing that it was just an apprentice, he said unhappily, "What's the matter?"

Qi Yu didn't care about her tone: "Teacher, hello, I want to ask, which floor are the literature books on cultivation methods? This library is too big, I really can't find it myself."

After saying that, he made a helpless gesture, and then intentionally or unintentionally showed the "mother's preference" on his right finger.

Seeing this, the guide looked at Qi Yu deeply, retracted his previous impatient attitude, and said in a calm and expressionless manner: "On the seventeenth floor are the methods of cultivation and the experience of the predecessors."

Then she looked Qi Yu up and down and said, "Young apprentices like you usually come here to look for magic books. There are magic books on every floor from bottom to top. However, the higher you go, the higher the level of magic, and the more difficult it is to learn."

"I'll give you a piece of advice. Choose a magic course that suits you. Don't aim too high, or you'll suffer." After the guide finished speaking, she lowered her head again and continued to read her thick book.

Qi Yu knew that the reason why she said so many instructions was entirely because Qi Yu had a teacher-level "motherly prejudice". If it was an ordinary student, she might have ignored him after giving him directions.

After Qi Yu thanked the guide, he walked upstairs. The spiral staircase made of solid wood led far upwards, and the "deng, deng" sound made by walking on it was particularly pleasant.

But now Qi Yu didn't have the heart to listen to how beautiful the sound was, or how beautiful the carvings on the stairs were. The only thought in his mind was: "Why doesn't this library have an elevator?"

Although Qi Yu knew that this idea was not realistic, because he had visited many buildings in the past few days and had never seen an elevator, so it was quite reasonable that there was no elevator here.

But it was hard for a "knowledge seeker" like Qi Yu. After climbing the stairs for a while, Qi Yu stood on the floor of the 17th floor, panting.

Then he looked around and found that compared to the lobby on the first floor, there were obviously fewer people. There were only a few people reading by the bookshelves.

As Qi Yu walked in the "bookshelf maze", he smiled in his heart: "Hey, they are tired too. The fewer people the better. No one will snatch the books from me."

He glanced at the books on the bookshelf and realized that even if he found the specific level, it would not be easy to find the information related to magic practice.

Because these books are too mixed, such as "The Cultivation and Self-cultivation of a Wood Elemental Mage", "Postpartum Care of a Wood Elemental Familiar", "That Time When I and My Senior Sister Practicing Dual Elements"... In short, there is everything.

After Qi Yu searched for 20 minutes, he finally found a book titled "Introduction and Foundations of Mana Cultivation" among thousands of books.

As Qi Yu opened the book and read, he finally understood how to improve this so-called magic power system.

According to the book, there is a way to improve in this world. One of them is to take potions. An excellent pharmacist can make potions that can increase the upper limit of mana.

However, this kind of medicine is generally very expensive. Except for those large families that have sufficient financial strength to cultivate talents, ordinary people do not have much chance to get access to it.

The second is the stone that can absorb the essence of magic power. This stone is said to be a star stone from the sky. During the falling process, it continuously absorbs magical energy, and then falls to the ground and is collected by people.

However, the amount of magic power contained in this star stone and the size and shape of the stone are different, so the price fluctuates greatly.

The last method, which is also used by most people, is to meditate in an environment that suits their own mana system, thereby absorbing the elemental mana wandering in the world to increase the mana limit.

Specifically, if you are practicing the wood element, you need to meditate in a jungle environment. If you are practicing the water element, you need to practice in an ocean environment, and so on.

After Qi Yu finished reading the whole book, he gently closed it. Of these three methods, Qi Yu only knew the second one, because in the game, it was to collect falling stars from the sky to increase the upper limit of mana.

As for the other two methods, Qi Yu had never heard of them, but relatively speaking, he was more inclined to the third one.

It was not because of anything else, but because Qi Yu was very poor now. Ever since Master Lin "scammed" most of his savings last time, his wallet has not been full again until now.

Qi Yu sighed. He originally thought that only the archer professions burned money, but now it seems that no profession can be successful without money.

Afterwards, Qi Yu found several books on the experiences of his predecessors and teaching materials on cultivation in the library, from which he learned the specific method of meditating to increase the upper limit of his mana.

In this way, Qi Yu unknowingly saw that the library was about to close.
