what happened? Why does the password box that looks like a dangerous item use the National Day of China as a password?

Then, after they had an idea, they found something wrong when they opened the Don't Hungry password box on the National Day, so they changed the dates such as Army Day and Party Day.

Then the passwords of the ten lockboxes are different, but the dates are all red and special. The mood of the people who were opening the box was indescribable, but they opened the box dutifully.

The dismantling expert with a gas mask opened the lockbox and found that there were stacks of paper and books inside, and his mood was still: "...".

"It's all books and A4 paper?" Others had a sense of fuss when they saw the contents of the box.

They recruited the armed police and the demolition experts so vigorously, and this is the result?

"There's something wrong, what's wrong with these books..." The dismantling expert who took off the gas mask said to others with a book, "The second volume of Chinese for the eighth grade... 2150... new textbooks."

"New textbook in 2150?"

Because of the time issue on the books, other people began to face the enemy again, and they all looked at what happened to these books and why they were textbooks written more than a hundred years later.

Others are very surprised at the source of these books. These people have graduated many years later. They don't know what the current textbooks look like and what they contain, but it is easy to compare some. .

As long as you find the current textbook for the second volume of the eighth grade, you can compare the differences between the two books.

"Here, this document is from 2165."

"The year 2165? Isn't that more than one hundred and forty years later?"

"Take these materials back first. We will study the book problem carefully. These materials should be very important." The one who made the call in the crowd said after looking at the materials in his hands.

"good."

The ten boxes were taken away, while others went to the research institute to ask where the boxes came from.

However, the address and telephone number written on the courier note on these boxes, and the store owner of this store are not known.

It seems that the logistics that everyone can check clearly can be found, but they have not found out where the courier is sent from.

And no one in the interesting shop called "Xiayue Grocery Shop" can find out who the owner is, where the shop is, and where their goods come from.

When Tianjingcao and Chlorococcus attracted attention, many people checked this store, but no one could find out.

There are many people called Xia Yue in the whole country, and it is impossible for them to check whether these people called "Xia Yue" are the owners of this shop.

Those who searched the store's information are still continuing to search, but the books and materials brought back have really made everyone study almost the same.

The books seem to be really like textbooks from 2165, from kindergarten to university computer science textbooks. The content inside is indeed a little more advanced than the current one, and the history inside seems to be real, not like it was fabricated.

The history book of the newly compiled textbook in 2165, from the third year of junior high school to the four-year history book of high school, wrote the major events that happened over the past hundred years.

When they saw the history book, it was like a prophecy book. The major events that happened from 2020 to 2165 are all in the history book.

In addition to history books, other disciplines also have very advanced technology, and more and more people are called to study the content of these books and materials.

Even if it is just a textbook, there are many technologies that differ by more than 100 years. The gap of 145 years still needs to be studied carefully.

In 2020, the people here are still checking the origin of the Xiayue grocery store, but Chen Xiayue is not worried at all.

What if it was found out that the owner of this shop was in the 1960s in a parallel world? They couldn't travel through time and space to find her.

1967, Northeast.

When the border guards were patrolling the border as always, they suddenly found several more trees. The trees with branches looked very familiar, but they couldn't remember what kind of trees they were.

"Why do I feel that this fruit looks a bit like grapefruit and coconut?" A little soldier from the south said looking at the fruitful fruit hanging on the branches.

"Grapefruit and coconut?" Another little soldier from the north was surprised when he heard the words, "Aren't grapefruit and coconut something only found in the south?"

"But, they look a lot like grapefruit and coconut," said the little soldier from the south.

Although I don't understand why these fruits look similar to grapefruit and coconut, they still picked some and sent them back to military doctors to study whether they can be eaten.

The products in the northeast are very rich, but when they come across some unknown fruits, they will still bring them back to let professionals know whether they can eat them and whether they are poisonous.

As a result, when the team of soldiers were picking rice crackers and oil nuts, someone accidentally discovered a cave that seemed to be hidden but not too hidden.

Then, just like the Land Warring States in the Yunnan-Guangxi region, they found ten abandoned trucks in the cave, full of tens of thousands of catties of grain, and ten password boxes.

Of course, these things have to be reported, not to mention the food and the ten lockboxes, the ten abandoned trucks are still very concerned about them.

These ten trucks don't look like they are unusable, and Xiu Xiu should be able to drive away. Therefore, for such an important thing, of course, I hurriedly contacted the above and sent it away.

The above quickly sent people over. Although the road conditions from the big city to the place where the troops were stationed were really not good, they still came for these ten trucks.

With ten trucks, tens of thousands of catties of grain are not so important to everyone. As for sweet potatoes and rice, the people above directly said, let the border guards stay here, whether they want to grow their own or keep it for them to eat.

Of course, the people who came from the rice fruit trees, oil fruit trees, and salt fruit trees that the warriors encountered also told them the usefulness of these fruits, and they were edible and very good things.

As for the sweet fruit, it is really edible, but the taste is too sweet. It seems to have the taste of concentrated honey, saccharin and concentrated sucrose. It is so sweet that it is absolutely impossible to eat it.

But you can't eat it directly, you can also use it to squeeze sugar. The juice of this sweet fruit is still very rich, and the extraction rate of the fried fruit juice into sugar should be very high.

The conditions on the frontier troops' side are very difficult, so with the high-yield sweet potatoes and high-yield rice as seeds, as well as rice fruit trees, oil fruit trees and salt fruit trees, and the existence of this sweet fruit, everyone should be able to live a little better.

As for the ten abandoned trucks and ten lockboxes, they were taken away by the people above. They had to go back and study how the trucks should be repaired so that they could continue to be used, and what exactly was in the lockbox.
