Back in his room, the cards Yun Jin had with him were still spread out on the desk.

Yun Jin opened the drawer, took out the [Book of Mysteries], and prepared to collect it to see what it was.

Holding the book in his hand, Yun Jin silently recited "Collect".

With a glimmer of light, Yun Jin felt that the spiritual energy in his body was much less. There are almost more than 40 attribute psionic powers.

Although it is not as good as today's [Death WeChat Group Chat], this consumption is also more than collecting some ordinary awakening abilities.

While thinking, Yun Jin picked up the card in his hand.

There is no difference between the card and the card of other magical items, they are all like jade, a thin piece, a little cool in the hand, there is no texture, there is no grade, and the central picture is the book.

It's just that there is some white mist floating behind the book, which looks antique and fairy.

The collection technique really worked, and originally Yun Jin looked at the inexplicable book, but the result was analyzed so thoroughly.

It seems that this is a book that comes with search, comes with translation, and can also randomly recommend books and store cards...

Hey, why is it so like an e-paper book.

Yun Jin said "Solution" lightly, and the mysterious book appeared in Yun Jin's hand.

This book is slightly larger than a palm, it looks antique, delicate and beautiful, and it feels very good to the hand on the cowhide.

It's just that Yunjin really can't understand why he uses kraft paper to origami, why there is a real kraft...

Yun Jin opened the mysterious book, and sure enough, the content in the book changed and became "The Three-Body Problem", the representative work of domestic science fiction writer Liu Cixin.

Yun Jin closed the book again and reopened the book, which was the content of the Nandu Daily today.

I have to say that the book of mystery is really good, it does not directly post the newspaper in the book, but reformats the newspaper.

The first page contains the name of the newspaper and the headline with an illustration, the second page contains the content of the headline, and the third page contains the second page.

Anyway, the content of the newspaper was reformatted and printed in the book, which didn't look like a sense of disobedience at all, and it was full of pictures and texts, which looked very comfortable.

Yun Jin did not continue to experiment, but flipped through the book and looked for bookmarks.

This book is also very interesting, after reading the newspaper, the back page is not a blank page, but a new magazine.

Yunjin finished renovating the magazine, and it was new again.

Yun Jin stopped his hand and continued to flip, this mysterious book is still [Information Flow], this is endless...

However, it is also impossible to slip the label in the page.

Thinking so, Yun Jin directly closed the book, turned it upside down, and then opened the back.

Sure enough, on the inside page of the back, there was a bookmark as thin as a cicada's wing, which was rectangular and had a blue bookmark rope tied to it.

Yun Jin took down the bookmark, opened the book casually, and then put the bookmark inside.

When Yunjin opened it again, the content of the book really hadn't changed, it was still "Harry Potter".

Yun Jin flipped through the front, and then flipped through the back, and he could continue reading.

It seems to be working.

After experimenting with this, Yunjin opened the first page of the book and began to store the cards.

Originally, Yun Jin's plan for this mysterious book was to place cards, and Yun Jin was still very happy to be able to retain this function.

But Yun Jin also expressed doubts about the book's ability to place cards, because a card is almost half the size of a palm, and a page can put two at most, how can it be possible to put four?

Thinking so, Yun Jin tried to place the card.

As a result, when Yunjin put the card into the page, something magical happened, the text on the page disappeared, and four placement bars appeared.

The card actually began to shrink, down to a quarter of the size of the page, and then obediently placed it in the placement bar in the upper left corner of the page.

Hey, there's still this feature.

Yun Jin put all the cards in this way, and then his mind moved, and a card appeared in his hand: [Unhappy Sunny Day Doll].

It really can.

Yun Jin thought about rearranging all the cards, and then he reopened the book, and the cards were arranged in a dazzling array of books, and they were all divided into categories according to what he had just thought.

There are [magical items], [psionic cards], [ordinary items], [ingredients], etc., anyway, the division is very clear.

And in front of each category, there is a special page with the name of the category written on it.

Yun Jin closed the book and opened it again, all the cards had disappeared, and it was still Harry Potter (with a bookmark on it).

Yun Jin was particularly satisfied with this mysterious book.

That way he doesn't have to carry a bunch of cards with him.

Hell knows how much space those stacks of cards take up...

At the beginning, when Yunjin needed to bring fewer cards, he only needed one pocket, but now let alone one, four or five can't fit the stacks of cards.

And when it comes to using them, these cards are still very difficult to find, and Yunjin has long wanted to change this situation.

After getting the book of mysteries, Yun Jin packed up, went out, and went to the supermarket to wholesale a bunch of food, his idea was that he didn't know how long he would go to the inner world this time, and he might have to go out on adventures often in the future, and it was always right to prepare more food.

So Yunjin bought boxes of ready-to-eat food, and all kinds of adventure supplies, and let the supermarket deliver them to your door.

In fact, if it is normal, the supermarket will definitely not deliver to the door, the problem is that Yunjin bought too much, so he made an exception and sent it over.

The boxes of things almost filled all the rooms, Yun Jin paid the money, closed the door with difficulty, and then began the great business of gathering.
