In the past, it was extremely difficult for outsiders to get in touch with their grandfather and have a meal with him.

But now Lin Feng is enjoying such preferential treatment, which makes her very puzzled.

Although Lin Feng did do a lot of things, could Grandpa really have other purposes for doing this? Thinking of this, Feni couldn't help but feel a little worried.

Lin Feng did not expect that Feiton would invite him so warmly, but since the old man had already asked, it was difficult for him to refuse.

Besides, it didn't matter where he stayed, and a day would pass quickly, so he nodded and agreed to Fedon's suggestion.

After a while, Feiton's wife Li Min also returned home.

After seeing Lin Feng, Li Min liked him very much and chatted with Lin Feng for a long time before starting to tinker in the kitchen.

As for Fanny's parents, they did not live here, so this three-bedroom, one-living-room house was not too crowded after Lin Feng joined the family.

For the next half day, the Felton family did not disturb Lin Feng, probably because they were worried that it would affect his performance tomorrow.

But they didn’t know that Lin Feng didn’t care about tomorrow’s exam at all.

However, after dinner, Feiton called Lin Feng to sit in the living room, while Fanny followed her grandmother to clean up the dishes in the kitchen.

"Lin Feng, actually I wanted to talk to you today mainly because you got full marks on the question I asked before, so I am very curious about this matter!"

"Grandpa Fei, what do you want to know?"

Lin Feng didn't know what Fei Dun meant, so he said it clearly.

"Don't get me wrong, I'm not suspecting you of cheating. After all, I came up with this test paper on my own spur of the moment, and I only sent it out half an hour before the exam started.

They also have to typeset and print, so it's impossible to find the answer in such a short time, so there's no way you can cheat.

What I want to ask is, apart from the positioning of the three bodies, do you have any other opinions on the aerospace field?"

At this time, Fedun finally expressed his intentions.

In his opinion, a person who can get full marks cannot be an ordinary person.

At least among all the students he had ever taught, no one had performed so well.

So he already began to have a glimmer of expectation in his heart. If Lin Feng really had a talent for learning in this area, then he could consider bringing him directly to the Aerospace Research Institute to work.

After all, money is just a string of numbers to Lin Feng. If he can create some achievements in this regard, he will basically be recorded in history.

Most people cannot resist such temptation, so Fedun is very confident about it.

After learning what Feiton meant, Lin Feng smiled and said, "I actually only have a limited understanding of aerospace.

If you ask me to innovate, I definitely don’t have the ability, but if you ask me about some of the existing knowledge, I do know a thing or two!”

Lin Feng smiled and said.

Although he now has a global knowledge base, this knowledge base can only find answers based on the knowledge currently known to humans in the world.

If Fedun asked him now to come up with a way to land on the sun, he would naturally not be able to find the answer.

"Oh? This is the first time I've heard someone say that they know something. Since you're so confident, I'd like to test you."

Feiton did not expect Lin Feng to be so confident. After all, most young people dare not say how much they know when talking about knowledge in the field of aerospace technology.

"Haha, then please let Mr. Feidon speak."

"Well, since you know about the three-body orientation system of the lunar exploration project, let me ask you, do you know why we chose to orbit the lunar pole this time?"

The previous three-body orientation theory knowledge is exactly the new technology used in China's latest lunar exploration.

Generally speaking, if you are a space enthusiast and have some theoretical knowledge, you will be able to understand the theoretical knowledge of three-body orientation.

However, this lunar polar orbit is theoretical knowledge that already existed. If we want to incorporate this knowledge into the lunar exploration project, we must have extremely strong organizing and understanding abilities, otherwise it is impossible to combine the two.

After listening to what Fedon said, Lin Feng's brain was already working at high speed.

Soon, a string of words appeared in his mind.

"The reason why we use the lunar polar orbit is mainly because it requires less energy to operate in this orbit, and the risk of launching and changing orbits is low. At the same time, in order to ensure that the lunar surface can be photographed and recorded at any position during the orbit, the orbit altitude must remain stable.

In summary, it is the perfect approach to have the probe orbit the lunar pole!"

As soon as Lin Feng said this, Feiton's face was full of smiles.

Even Fanny, who was washing dishes in the kitchen, heard some of it.

Although she knew something about circling the lunar pole, it was only because of her grandfather's long-term influence.

In addition, even if she already had knowledge in this area, she was not sure she could answer the question so quickly and fluently just now.

The answer to this question is still completely flawless.

"Okay, okay, Lin Feng, I didn't expect you to be so knowledgeable about aerospace. Next, I will ask you some other questions."

After Fedon finished speaking, he raised some questions again, but this time some of the questions were very in-depth and more detailed.

But relying on the powerful global knowledge base, Lin Feng was able to quickly find answers to all the questions raised by Fedon.

This also made Felton quite excited, and he became more and more excited the more he talked. In the end, even Fanny couldn't help but run over and sit down to watch the two of them talking.

"Lin Feng, I think there will be no problem if you come to work here now. We don't lack operators, but we are in need of people who understand theory and technology!"

After talking for a whole night, Felton couldn't help but extend an olive branch to Lin Feng on the spot.

This was something that Feni and Lin Feng had not expected. After all, aerospace research was a matter of great importance, so how could they just recruit anyone?

However, although Lin Feng felt that he was indeed capable of working there, he had no interest in working there.

"Grandpa Fedon, you know that I still have to focus on my studies. As for where to work, I want to make plans after graduation."
