Jiang Shixun's heart was beating fast.

His mood was extremely complicated, and his mind was full of all kinds of guesses.

Because of the same text, he subconsciously thought the book in his hand was a book from the future of Longguo, and didn't think about the parallel space at all.

After all, no one had proposed the theory of parallel time and space at that time. No matter how smart Jiang Shixun was, he could not think of this.

The reason why I thought that Shennong Space could connect to the future was because the publication date on the book was obviously not now.

If he regarded the book in his hand as something from the future, he could think of a lot more.

The excellent printing quality of this book indicates that future printing technology will undoubtedly be far superior to today's. Not only printing technology, but also photography technology, even papermaking technology and ink technology will likely be far superior to today's.

The images in this book are so clear, they must have been taken very clearly when the photos were taken. In addition, the printing technology is also good, and the ink used is bright and rich in color, so the final printed images are so beautiful.

In fact, the first inkjet printer was invented abroad in 1976, but Jiang Shixun was in China and did not know about it.

And it wasn't until 1991 that the first color inkjet printer was introduced.

Later, more advanced laser printers became available.

Of course, Jiang Shixun couldn't know all this at the time. He saw the pictures and text printed in the book and could only make guesses based on his existing knowledge.

Looking at such a book, he felt extremely excited, as if he had seen the future Dragon Kingdom through it.

At the same time, he was also full of expectations for Shennong Space.

Since it can connect to the future, will other things from the future appear in the future?

What else could it be?

Unfortunately, Jiang Zhiying didn't know what he was thinking at the moment. She was feeling guilty and was afraid that Jiang Shixun would see through her and suspect her identity.

So she tried hard to act stupid, and as long as Jiang Shixun didn't notice her, she pretended that she didn't exist.

Unfortunately, Jiang Shixun soon set his sights on her.

He looked at Jiang Zhiying with burning eyes and asked anxiously, "Zhuzhu, do you still have this kind of book?"

Jiang Zhiying hesitated for 0.01 seconds and said decisively, "There are a few more."

She has collected quite a few books. When she first collected them, she thought the knowledge in the books was very useful, so she has never been willing to throw them away.

However, she didn't dare take out all the books now because she hadn't finished cleaning up yet.

There were so many books that she didn't even know which ones they were. If she took them all out, what would happen if something went wrong?

And judging from Jiang Shixun's expression, he was obviously shocked.

What if we take out all those books and they give him a heart attack?

Jiang Zhiying took out the books she had selected in advance, including those on raising chickens, ducks, fish and livestock, and those on deep processing of agricultural and sideline products, as well as the books on tractors, planters and harvesters that she had shown Xiao Lin before.

There aren't many books here, but if you take them all out, there are actually quite a few.

She put the books in a storage box, which happened to be a big storage box.

Jiang Shixun and Tang Yulan had seen this kind of box before, so they were not surprised when they saw it, but were just curious about what was inside.

The box is opaque and you can't see what's inside.

So as soon as Jiang Zhiying took out the box, Jiang Shixun couldn't wait to open the lid.

Seeing the neatly arranged books inside, he and Tang Yulan both gasped in surprise.

Tang Yulan exclaimed: "So many books!"
