"If you have the ability to do it now, why not do it! Even if you do it now, it's not of much use? In short, it's still planning for the future, saving time for some things in the future, isn't it?"

Originally, Li Nan saw that he was constantly improving his research status when he spoke, and thought that he was a person who cared about reputation very much, but now these words made Li Nan look at it a little differently.

"I didn't expect my uncle to have the mind to be a behind-the-scenes hero, okay, I have to say sorry, no matter if the experiment can have any results in a short period of time, whether it can be of any help, but I shouldn't dampen the enthusiasm of activists!" Li Nan bowed slightly apologetically to Zhao Yuhuai.

"Where, where! I didn't expect that classmate Li would still have research on these things!" Zhao Yuhuai smiled and invited them to sit down, and then pulled up a rare starry sky map from the side for Li Nan to show them.

Although many sky maps can be found on the Internet, what is found on the Internet is obviously different from what researchers have in their hands. Needless to say, perfection, comprehensiveness and the like, the clarity is far from comparable.

Many high-definition starry sky pictures are really big, and a picture may occupy more memory than a movie.

While showing them, explain to them at the same time.

Although Li Nan knew everything he said, and even knew much more than him, he was not disappointed, and still pretended to listen attentively on the side.

Sometimes, there is no need to deliberately show one's knowledge, people are social animals, and they praise each other, and humility is a very good thing to interact with each other.

Ji Dong did listen patiently at first, but the deeper the astronomy knowledge is, the more boring it is, if it is just a simple popularization of science and a little story, it can still be barely listened to, but if it touches on the academic side, then it is inevitable to bring some physics knowledge.

In this way, it is strange that Ji Dong is interested, explaining some physical constants and gravitational coefficients to a student who has just learned physics such as acceleration is simply sick in the brain.

Fortunately, he didn't keep talking about it with such enthusiasm. When he stopped and said that he was going to take them to the astronomical telescope above, Li Nan could clearly see that Ji Dong was relieved.

Sometimes it's true, although everyone knows that when they encounter something they don't like, they should clearly say no, but when the real thing comes, there are a few who can clearly say no!

"Actually, daytime is not a good opportunity to see the sky, because of the sun's light, even if you add a filter, you can only see a few planets.

Normal daytime is mainly to look at the sun, to see some special fluctuations on the surface of the sun, sunspots and the like, but this depends on the timing, and there is definitely no today. Zhao Yuhuai said as he adjusted the parameters of the astronomical telescope for them.

Li Nan accompanied Ji Dong to take a few symbolic glances, Ji Dong was quite interested, and reluctantly looked at the sun with an astronomical telescope.

After a while, when it was almost noon to have lunch, Li Nan finally found a lot of excuses to leave, originally Zhao Yuhuai had to keep them for lunch together, but Li Nan took his mother as a raft, and finally got away and rushed home.

Along the way, I also deeply felt that Ji Dong, an uncle surnamed Zhao, must have a hole in his head.

He said he had come here to build the Astronomy Expo to increase interest in astronomy in remote areas. It's remarkable to be able to find such an unreliable reason for the reason.

Li Nan didn't bother to explore the real reason, no matter what he wanted to do, he shouldn't be able to have any bad intentions in his brain anyway. I guess it's either that there's something unspeakable, or that I'm trying to find a relatively secluded place to do research.

At noon, it is still the usual four dishes and one soup, two meats and two vegetables and one soup.

Li Nan is really not very happy to eat it, after all, these soups and dishes are still a lot of pollution, at least in Li Nan's eyes. However, in order not to sweep my mother's happiness, I can only reluctantly serve a little less, eat a little side dishes, and plan to leave after chopping and pulling.

"Stop, if you have a cat, you can eat so much cat food! Your sister eats more than you, why, you're hungry after a day of going out to play!" Ji Juan was a little worried, in her opinion, Li Nan was the time to grow her body at this age, how could she be full just by eating this?

Li Tong's face fell, and he didn't feel that eating more than Li Nan was a compliment: "Brother, you shouldn't be losing weight!"

"Can you have some good ideas, I can't come back after eating outside, I can't eat snacks outside, so I won't be hungry when I come back?" Li Nan also obeyed them, eat less food, as for such a fuss.

"How many times have I said it, don't eat those junk foods outside, and fast food should be less ordered, I didn't have time to cook for you before, but now I have time to do it, how can I go out to eat fast food or something!

What's the matter, don't you think my mother's cooking is unpalatable?" Ji Juan said with a dissatisfied face and put down her chopsticks.

"Mom, I'm just not hungry!"

"You're still an immortal, you, you won't eat it in the future if you have the ability!"

Li Nan didn't answer, and went back to the bedroom with his apologies.

For an ordinary mortal who doesn't have any golden fingers, this meal is indeed not unpalatable. But for Li Nan, just overcoming the various bacteria and microorganisms wrapped in the rice without looking at those dishes is quite difficult.

After returning to the bedroom, Li Nan also deeply felt that there must be a solution to this matter, because he couldn't eat such a little bit at every meal, and the most important thing was that Li Nan didn't want to eat at all.

"That's right, wouldn't it be okay for me to bring the dust-free array cloth to my own house?" Li Nan suddenly patted his head and thought of such a solution.

At the beginning, he wanted to rely on the technology of the Tunguska Empire to solve the problem, but after thinking about it, no matter what he did, the technology of the Tunguska Empire could not be silent, so that his family did not have the slightest bacteria and microorganisms.

But on the cultivation planet, many monks on the cultivation planet will arrange dust-free formations, in order not to contaminate all kinds of bacteria and microorganisms in the mundane things.

Li Nan also bought a few before, but he never remembered to use them, and this time he immediately took out all the things related to them that he had originally bought from the space.
