Dreaming back to 90, starting to develop B2 bombers!

Aerospace Engine! Yu Bei’s guilt! 【Please order in full】

“Haha, Mars is really good. If we can get here, it will definitely be a powerful and solid line of defense for extraterrestrial civilizations!”

Cheng Hua nodded, still very satisfied with this location choice.

Xu Guo also smiled and stroked his beard.

But Hu Weinan frowned. As the president of the Academy of Dragon Science, he was naturally more knowledgeable than generals like Xu Guo and Cheng Hua who were galloping on the battlefield.

Although Mars is extremely suitable for an extraterrestrial military base in terms of distance and other aspects.

But there is a very critical issue here.

That is, this distance is Mars’ advantage, and of course it is also its problem! !

Taking a deep breath, Hu Weinan decided to voice out his worries. After all, if he didn’t voice out his worries at this time, the project and the production of related machines would have been confirmed later, and “663” would be in trouble by then! !

“In the north, the distance between Mars and Blue Star is different due to the rotation and revolution of the two planets. As of now, the short distance between the two places is about 55 million kilometers, and the farthest distance is more than 400 million kilometers. The two Close encounters between planets occur approximately every 15 years. In 1988, two years ago, the distance between Mars and Blue Star reached approximately 58.8 million kilometers.”

“According to the trajectory and speed of the two planets, it should be about 70 million kilometers now. According to the speed of our current aircraft, it will take a very long time to reach this distance, maybe even three years!”

Hu Weinan said, his voice a little heavy.

Although Cheng Hua and Xu Guo didn’t understand what Cheng Hua explained, their expressions changed immediately when they heard that it would take three years! !

You must know that the reason why Yu Bei is so anxious now is that he wants to build a defense line in a short time.

In this case,

can build a line of defense for Daxia and Blue Star, but if it takes three years now, then there are too many things that can be changed in these three years! !

Maybe by then the foreign civilization has already attacked, and their defense line hasn’t been set up yet! !

“What can we do? We can’t wait as long as three years!”

Cheng Hua, who has long been accustomed to using months as his research and development time unit in Bei, couldn’t help but stood up anxiously when he heard this! !

Hu Weinan shook his head with a wry smile on his face: “There is really nothing we can do about it. Ever since we young men sent our satellites out, we have not made any progress in aerospace in Daxia for a long time! The most important thing is in terms of engines. At present, It’s simply difficult for us to have more breakthroughs.”

But at this time, Yu Bei smiled.

Although people were still very nervous, they were stunned when they saw Yu Bei laughing. Cheng Hua turned to look at Yu Bei and asked,

“What’s wrong, Yu Bei, is there anything you can do?”

Hu Weinan also looked at Yu Bei with a puzzled look.

Yu Bei smiled: “Dean Hu, Mr. Cheng, Mr. Xu, have you forgotten that we now have controllable nuclear fusion technology! We can completely use the controllable nuclear fusion technology to build another one specifically for aerospace.” engine! I believe that such an engine can definitely meet the power needed for aerospace.”

Suddenly, when he heard Yu Bei’s words, he was stunned, and then he couldn’t help but smile: “I really forgot about this! But, Yu Bei, you are nowDo you have time to build this engine? ? ”

“Of course Yu Bei has time. Is there something wrong with him?”

Cheng Hua said with a smile.

When Hu Weinan heard Cheng Hua speak, he smiled and shook his head, looking at Yu Bei, obviously knowing something.

Yu Bei then scratched the back of his head in embarrassment.

“Mr. Cheng, I really have something to do.”

Yu Bei said.

Being slapped in the face by the speed of light, Cheng Hua was a little embarrassed, but facing Yu Bei, he couldn’t get angry, so he asked with concern: “What’s wrong? What happened to Yu Bei? Are there any difficulties? ?”

Xu Guo also looked nervous: “What’s wrong? What happened to Yu Bei? Tell me quickly!!”

Yu Bei coughed awkwardly, “Well, it’s like this, Mr. Cheng, Mr. Xu, my girlfriend’s birthday is in a week. I thought I might as well celebrate her when I go back. You also know that I have been busy these days. She still doesn’t pay much attention to work matters, and if she hadn’t sent me a letter, I would have forgotten about it.”

What Yu Bei said was sincere.

When Cheng Hua heard what Yu Bei said, he suddenly realized.

Then he smiled and nodded, feeling much more relaxed and happy than the contract. After all, they still care about Yu Bei’s personal affairs! !

After all, the father is so smart. Maybe the son he will give birth to in the future will be equally smart, or even smarter than his father. In that case, it will be a huge asset to Daxia! !

“Haha, Yu Bei, what’s not to say? This is a serious matter. Don’t just focus on work and neglect your girlfriend!! Go back quickly. Anyway, even if we are in a hurry, we won’t be in such a hurry. God’s time!!”

Cheng Hua said with a smile.

“Ah, Mr. Cheng, I plan to go back in a week. Is it too early to go back now?”

When Yu Bei heard Cheng Hua’s words, he was stunned for a moment and then said.

“Are you stupid? I told you to go back now. Wouldn’t it be better for you to go back now and spend more time with your girlfriend?”

When Cheng Hua saw that Yu Bei was still confused, he couldn’t help but said.

Yu Bei nodded.

“By the way, have you prepared any gifts? People celebrate their birthdays once a year, so you don’t want to give them nothing, right?”

Cheng Hua looked at Yu Bei and asked again.

Yu Bei shook his head in embarrassment.

At this time, even Xu Guo couldn’t stand it any longer. One of his beards was torn off!

“Ahem, Yu Bei, let me ask you, what’s going on! Fortunately, it’s your girlfriend, she has a good personality 1.2! If it were another girl, it would be weird!!”

Xu Guo coughed and then said.

Hu Weinan also smiled and nodded: “It’s time to buy a gift.”

Yu Bei scratched his head and asked, “But I really don’t know what to give. I don’t even know what she likes…”

Yu Bei said, but he was stunned before he finished speaking. The guilt in his heart suddenly surged up.

He and Leng Weiwei have been together for so long, and he actually doesn’t even know what Leng Weiwei likes. As a boyfriend, he is such a failure! !

Now that I have to give birthday gifts, I feel like a headless fly. I even have to ask Cheng Hua and Xu Guo, the older generation, to teach me! !
