?? In the face of this urgent situation, there is only one way, and that is to skip class, or pretend to be sick.

It's no problem to miss a day or two of classes, but if you miss this opportunity, it will be difficult to get the identity certificate of the Tunguska Empire through formal channels.

If you get the identity certificate of the Tunguska Empire, you will be able to smoothly learn this knowledge and serve the motherland when the time comes! The value created in this way will definitely far exceed the value of two days of ordinary cultural classes.

Thinking of this, Li Nan was moved by himself, he was simply too selfless, which was obviously skipping classes for the progress of the country and the development of the nation. Such a truancy is undoubtedly great, bright, and just.

After assigning the spaceship to his bedroom, he thought that it was still early anyway, so he didn't rush back, so he manipulated the light brain to make a protruding flat stool behind the door, and then sat behind the door and played with the light screen here.

This light screen is not bad, although the main function is to manipulate the entire bedroom interior, but it is also able to access the Internet, but at present, Li Nan's permission is very low, which is equivalent to a tourist, and can only view some ordinary entertainment information.

Li Nan has no interest in studying for a short time, so he wants to find something to entertain him, but who knows, almost all the videos in it only have trailers, and the feature films are charged, and he doesn't even have an identity certificate, where is the credit here?

The same is true for novels, only the first 20,000 or 30,000 words are free, and the rest have to be charged, and there is nowhere to find pirated copies. The most terrifying thing is that even the author has been dead for many, many years to be charged. When the author was alive, there was no electronic version of the novel on the Internet, and there was also a fee.

After Li Nan checked it, he was completely dead, except for news and information, there is no charge here, and nothing else is free.

At this time, I was curious to go to some early childhood education, well, that's right, early childhood education also has to be charged, it can be said that on the Internet, but everything related to knowledge and copyright, there is no free.

Li Nan, who had already felt penniless here, suddenly thought of something, cheered up again, and began to search for the price of gold in the Tunguska Empire.

Because he doesn't have any currency here, even if he gets a citizenship certificate, if he wants to get something, he has to pay, so how to get this currency has become the most important thing.

But after checking the price of gold, Li Nan was completely desperate, and the price of gold here was also very cheap, because they already had elemental (not magical elements, or simple gold, silver, copper, and iron) collection equipment here.

For example, although the gold element in the sea is very thin, after all, such a large capacity is there, as long as it can be extracted, it is not a problem to extract a trillion tons.

This is the role of elemental collection equipment, and this is only one of the points, there are many various mineral planets in the Tunguska Empire, and there are even planets made entirely of gold elements, so for them, gold basically has no value except for the appearance of the jewelry made of it.

Li Nan, who didn't have great expectations, searched the price of jade again, which can be regarded as a relief, although the price of jade here is not high, but it has not fallen into the dust.

The main reason why the price of jade is barely able to support it is that not every living planet has jade deposits, and there are no planetary stars composed entirely of jade. In addition, jade is not made of a single element, and there is no way to use an elemental collector to collect and make it.

Therefore, although the jade deposits of the Tunguska Empire far exceed the planet where Li Nan himself stays, the number is also limited, and it can barely maintain the price of low-grade jewelry raw materials. Unlike gold jewelry, it's basically a bargain in the wholesale market.

The real precious things on the side of the Tunguska Empire are some star metals in the universe, or substances with special radiation, or rare mineral deposits on some planets.

Of course, there are actually two main types, one is particularly rare, and the other is particularly useful.

Li Nan searched a little out of curiosity, hehe, none of them were known. At the top of everything inside is the star core, which is the core of the stars, and not all stars have it, as for what kind of stars will have this thing in it, they haven't figured out the law yet.

According to the description on the Hunt List post, there are only three of them in the entire Empire, one of which is an Imperial Royal Collection, embedded in the top of the scepter, one is a symbol of honor in the Imperial Council, and one is in the Empire's Supreme Academy.

When Li Nan continued to look down, he flipped through to the items that ranked more than 1,000, only to find that something he knew, in fact, he couldn't say he knew, he could only say that he knew, that was uranium ore.

However, this thing is not highly evaluated, and the unit of measurement is still calculated in thousands of tons, which is not at the same level as the above things that are calculated in units of measurement such as grams and micrograms.

The evaluation is also very clear, and the main reason why it can rank this position is because it was in an important energy position in the early days of the empire. To put it in this ranking, the historical symbolism far exceeds the actual value.

Li Nan no longer continued to turn down, and the more he flipped over, the more he felt that his country was backward, and it might not even be just the country, but the backwardness of the entire civilization.

But the loss came and went quickly, and it was soon brought away by other interesting things.

Although the knowledge on the Tunguska Empire network needs to be paid, but there are discussions among netizens, and some personal sharing posts are free! Some of them are more biased towards civil science forums, and some of the posts in them still have some value.

Because Li Nan saw a lot of incomprehensible things in it, what string theory, and what practical significance of space compression. Although there may not be many really useful things in it, there is a little bit of encompassing knowledge in the end.

Li Nan wrote down a few impressions a little, and prepared to go back to the Internet to see if there was anything related to them in his world.

When a person is focused on one thing, especially on the Internet, time flies really fast.

Li Nan felt that he hadn't even read a few posts, and the watch he was wearing had already sounded slightly, reminding him that it was six o'clock.

remembered that her mother said that she would come back at six o'clock in the evening to make dinner, Li Nan quickly turned off the light screen and went back immediately.

"General, the signs of life in the spaceship have disappeared!" A few seconds after Li Nan disappeared, someone informed Cayos of the news through an alarm.

It is true that there is no surveillance installed in the ship's bedroom for reasons of privacy. But the entire spacecraft has a life monitoring function, and every one of them is alive and has a bright spot on the spacecraft life monitor.
