There is a small inconspicuous volcano in the Valley of the Craftsman, and its height can only be regarded as ordinary, which is not noticeable at all. If it weren't for Junwu bringing Li Yu over, Li Yu wouldn't have known that there was a special cave here.

"Ice and Fire Cave!"

"All the books you want to read, here. This cave is regarded as the library cave of the Valley of the Craftsman, and the disciples in the valley can come to the cave to browse as long as they meet the requirements. ”

Jun Wu explained to Li Yu that the Valley of the Craftsman God was built in a volcano, mainly to facilitate the use of fire to strike iron, but it was not convenient to store books.

"Ice? Is there ice in the volcano too? ”

Of course, Li Yu also understands that nothing in this world is impossible, but volcanoes are connected to underground magma, what kind of environment can produce ice in such an environment?

"Yes! But no one knows why, it's in this cave of ice and fire. ”

It was Qing'e who answered, because Li Yu helped her speak, so even if Jun Wu provoked her, she followed with a dead face.

The Ice and Fire Cave is not deep, and it is also very open inside, and it can be seen from the naturally solidified magma on the cave wall that there is no trace of artificial excavation, and it is completely naturally formed.

When I got here, I could already see many disciples, and it was natural to read books, and no one made noise.

Seeing the rows of bookshelves and a table, Li Yu had the illusion of being in a library.

"All the books in the Craftsman Valley are here, and they are placed on different shelves according to their classification, and they are about the formation over there."

Jun Wu pointed to a large bookshelf in the corner, Li Yu glanced at the large bookshelf several feet high, and estimated that there must be tens of thousands of books. It's also a loss that the people who read the books are immortals, and if they are mortals, it is a big problem to take and put the books.

"Huh?"

Li Yu picked up a book casually and found that there was no defense ban. There are no other prohibitions other than the Dust Shelter Charm.

"There's no defensive ban on this book?"

Li Yu asked suspiciously.

"The books here are all made of paper made by the craftsmen themselves, and the grade is extremely high, even the heavenly immortals can't tear them, and the golden immortals can barely make wrinkles in the paper, so that the Da Luo Jin Immortals have the ability to tear them.

But how can there be a big Luo Jinxian who would be bored to run to the Craftsman God Valley to tear up the book? ”

Li Yu also found that the book itself was extraordinary, but he didn't expect it to be made by the craftsman himself.

"The craftsman makes it himself, the cost is quite high, how long do you have to make so many books?"

Li Yu just sighed.

"Idle!"

Jun Wu sighed and said, there are so many craftsmen and gods, they are indeed idle, and they can't find anything interesting to do, like him, Jun Wu is an idle and panicked craftsman god.

There is no defensive ban, which is convenient for Li Yu.

"Scan all the books, gather information."

If you scan it in the cloud, you can write down as many books as you want.

The books here are not only limited to refining tools, formations, etc., but also Feng Shui, astrology, arithmetic, geography, materials, etc., as well as poetry and music.

"It's really all-encompassing, and it's a treasure trove of knowledge."

These are all ordinary books, and they don't have the same charm as in the Book Mountain Array, so they are collected quickly.

Three days later, Li Yu included the contents of all the books in the Ice and Fire Cave.

Qian Yinxue stayed by Li Yu's side, playing with her hair when she was bored, and she couldn't read a book.

"Junwu, do you have all the books here? Is there anything else? ”

When Li Yu found Junwu, he was talking to Qing'e, and to put it bluntly, he was still persuading the girl to give up. But Qing'e is very happy, it is better for Jun Wu to persuade her than to ignore her, at least not to avoid her.

"It's almost here, and we don't allow books to be taken with us."

Qing'e saw that Jun Wu pondered and did not answer, so she answered for him.

"No, there's a book. At the place of Luban, the god of carpenters. It's a "General Outline of Refining", and that's a real treasure book. ”

Jun Wu explained. Lu Ban, the carpenter god, lives in the mountains and forests outside the Craftsman God Valley, and generally does not come to the Craftsman God Valley if he has nothing to do.

"General Compendium of Refining? It's kind of interesting, let's go, go borrow it and take a look. ”

As soon as Li Yu heard that it was a treasure book, he became interested.

"That book already belongs to him, although that person is not stingy, but his temperament is also very strange, and it all depends on his mood, I'm afraid it's not easy to borrow."

Jun Wu persuaded him that he had also read the general outline of refining, which was divided into three parts: famous objects, refining, and experience. Many of these books in the Valley of the Craftsman God were written according to the General Outline of Refining.

"It's okay, it's not up to him to decide whether to borrow or not."

Li Yu said that he wanted Jun Wu to take him, so the group of four people went out of the Craftsman God Valley with great momentum.

The mountain forest opposite the Craftsman Valley is large, and each tree is a towering tree, and many birds are shuttling between the trees, chirping.

"Ha, what a good forest! The mountains and rivers are beautiful, the birds are singing and the flowers are fragrant, quiet and peaceful......"

Li Yu received the influence of the atmosphere and couldn't help but admire.

Not long after he finished saying this, he heard the sound of cutting and sawing trees from the depths of the mountain forest, and with a "down", a big tree fell down.

At the same time, a flock of birds was frightened and rushed into the sky.

"I should have thought of it a long time ago, a group of carpenters must have cut down trees, and the ghosts are clean and peaceful."

Li Yu took a sip, wondering if to take a few trees from it, anyway, how big the trees here are, and it is nothing to have less.

"There's someone up there, it looks like you're almost there."

Qing'e also rarely goes out of the Divine Valley, and she gave up too many things in order to wait for the rabbit and other kings. Approaching the green mountains and old forests, feeling the breath of life, the mood was suddenly much happier, and the cultivation that was stuck in the bottleneck also felt a little loose.

"Hey! The kid who cut down the tree, come on, come here! ”

Li Yu saw a group of people dealing with the big tree he had just cut down, so he craned his neck and shouted.

It doesn't matter if it's not good, Li Yu said that he stopped all the work under his hand and twisted his neck to look over.

"Huh? Why can't you come? That's right, it's the kid in open crotch pants, don't look at it, it's you, hurry up, uncle will give you candy to eat. ”

Li Yu pointed to a tall man and said, people don't wear open crotch pants, but the shorts are a little fat, maybe they were cut by a branch when they were working, so they were called open crotch pants by Li Yu.

"Me? I'll go! Where did the neurosis come from, dare to humiliate me! ”

The big man was chopping tree branches with an axe, and when he heard Li Yu's words, he came over with an axe and a fierce attitude.

"Boy! Who is it called? ”

The big man said angrily.

"What about calling you a boy? I didn't hear me and called again. Brat! Brat! Brat! Say the important thing three times. ”

The big man's puffing appearance is also quite funny, and Li Yule is playing with him.

"You!"

This person's brain is relatively straight, and he can't turn so fast at once, and the more Li Yu talks about him, the more angry he becomes.

"Boy, come, uncle will give you candy."

Li Yu said, and really took out a piece of candy, or White Rabbit milk candy.

Dahan looked at the candy in Li Yu's hand, and his eyes were glaring, and he couldn't spit out a word of anger.
