Datang: The prince of salted fish was overheard by Li Er

[What, can this system be upgraded? 】

[System, will there be any changes after the upgrade? 】

Li You began to keep asking the system in his heart.

However, the system ignored his question and just continued to make a beep.

"During the system upgrade, the rewards for signing in for one kindness per day will be suspended, and the kindness completed by the host will exist in the form of kindness points."

"The amount of kindness points will directly affect the upgrade speed of the system and the quality of the upgrade."

"The original upgrade time is 100 years."

"Currently the host has 25 five points of kindness, which can increase the speed by 420%. Now it will take 50 years."

"Please host to do more good deeds to speed up the system upgrade."

"During the system upgrade, the system graphics and video room is open to the host. I hope the host can make good use of it and do more good deeds."

"Lovely host, look forward to meeting again after upgrading."

I don't know if it was Li You's illusion or what, the last sentence of the system no longer sounded so blunt to him.

However, after the last sentence, the system entered a dead silence, even if Li You asked any more questions, he would not say a word.

This made Li You, who was so excited about getting the education team card and steel workshop just now, feel a little bit disappointed.

In this year, it was precisely because of the existence of the system that he was able to gain a firm foothold in Datang. Otherwise, with his temperament, he would have died countless times in this era.

Although the system can hardly communicate with him, Li You feels that the system has always cared about him, and will always give the best rewards at the most critical times to help him overcome difficulties time after time.

After being lost for a while, Li You cheered up again, life still had to go on, this system just started to upgrade, it didn't leave him.

Besides, isn't he still able to use the system's graphic and video room now?

[How to use this graphic video room? 】

Just when Li You had this idea, a house appeared in his mind, and then he seemed to have entered the room.

The house is very simple, there is only one desk, and there is something like a computer in front of the desk.

Looking at everything that was familiar and unfamiliar before him, Li You was filled with emotions.

After a year, he finally saw something related to modern civilization again.

Sitting decisively at the table, Li You quickly figured out how to use the so-called graphic and video room.

In fact, it is very simple. The computer in front of him is similar to the retrieval terminal of the library.

Enter the information you want to search on, and the book you want will appear.

After choosing, the desired graphic information will appear in front of him.

With the mentality of giving it a try, Li You entered the word "Zhenguan".

Then, more than a dozen books related to Zhenguan appeared in front of his eyes.

Li You was doing an experiment, so he didn't check it carefully, and then he entered a keyword "seventh grade math paper" on a whim.

Then, the familiar book appeared in front of him.

[I'm going, how many things in the graphic and video room did the system take as rewards for me! 】

Shocked, Li You searched all the reward books he could think of, and sure enough, the system did not disappoint him.

All the books that were given to him as a sign-in reward before came from this graphic room.

The only thing that made Li You feel a little relieved was that he could only read the books here, but he couldn't take them away.

But even though it can't be taken away, the power of this graphic and video room still deeply shocked Li You, making him unable to calm down for a long time.

[Now that I have an excellent education team, when I slowly dictate these books and let them help me cultivate talents, Datang's technology will not take off in an instant. 】

[At that time, what are the Turks afraid of? Labor and capital will directly drive tanks to conquer the world. 】

As soon as he said it, Li You directly searched for the tank design.

However, this time, the books given by the system were all descriptions of popular science, and no detailed design drawings appeared.

Li You was not reconciled, and searched for a few keywords of heavy weapons.

After a lot of work, he finally had to accept this reality with regret.

That is, although there is a wealth of information in this graphic and video room, none of the information that is classified as confidential in modern times can be found.

In other words, this graphic and video room is similar to a large modern library except that there are more ancient books that have been lost.

What's more, Li You felt a little cheated because some books on modern science and technology were actually in the original English version.

[I'm going, this means I have to teach those Tang people English. 】

[I hope there will be an English teacher in the team this time! 】

[Fortunately, the system was given to Wu Leichuan and his team. Their era happened to be the era when the Qing Dynasty just started to accept Western science. 】

[I think the situation should be similar to those students in the new school now, let them teach, there should be better results. 】

[Mmm, the products produced by the system are indeed all high-quality goods! 】

After finding that there were not many shortcuts, Li You exited the graphic video room resentfully.

This time, he discovered something even more shocking.

He felt that he stayed inside for a long time just now, but after he exited, he found that time did not flow at all.

[Wow, time pauses!In this way, I can't do a lot of things and learn a lot of things in it! 】

[This thing is simply amazing, but it's a pity that there is no need to take the exam now, otherwise it would be a proper artifact for the exam! 】

In the graphic video room just now, Li You also discovered the prop cards and workshops that he had not used yet, as well as the place to check the current kindness points.

Now the system won't directly promote him, everything can only be done automatically.

After exiting the graphic and video room, Li You understood what he urgently needed to do next.

That is to do good deeds. Regardless of the fact that the original time for the system upgrade was 100 years, the goodwill points he accumulated in the past year can speed up the system by 25%, which is 20 years less in one fell swoop.

In other words, if Li You continues to do good deeds at the current speed, and the impact of accumulating kindness points on the system update remains unchanged, the system will be upgraded in about 15 years.

15 years, short is not short, but long is not long.

Moreover, if Li You felt that he was not so salty, maybe the speed of gaining points could be much faster.

For example, do a good deed every day, instead of perfunctory like helping a broom.

Li You felt that doubling the points might not be realistic, but 40 a year is still very possible.

Li You went into the graphics and video room to do some calculations, and came up with the result that the upgrade can be completed in only ten years.

[Hmm, in order to be a salted fish for a lifetime, it seems that I still have to work harder. 】

[Then let me see how this new teaching team is doing now. 】

Half an hour after Li You used the team card, an unexpected person appeared in front of Li You.
