"Are you brother in a daze?"

Seeing Ye Fan lying in front of the computer without moving, Ning Xi pulled up in confusion, and pulled down the corner of his clothes from the audience.

Ye Fan came back to his senses and inserted his right hand into the pocket of his shirt.

The next second, a card that looked like a card size appeared out of thin air in his palm.

He pinched the card and thought to himself: "Nan Ying fell into a deep sleep now. Does it mean that the system's restrictions on him have disappeared?"

Thinking of this, Ye Fan's eyes lit up and he turned around and said, "Xiao Xi, there is something important to tell you."

Ning Xi blinked curiously, "What?"

Ye Fan took a deep breath, his expression was extremely solemn, "Xiao Xi, actually I..."

The voice came to an abrupt end.

It was not Ye Fan who did it intentionally, but that he could not make any sound at this moment.

Lan Ying's sleepiness did not touch the system's restrictions, and the existence of the system was still unspeakable.

Ning Xi stared at Ye Fan for no reason, "Brother said whatever he wanted to say, why did he stop talking?"

"Ahem—"

Ye Fan sighed lightly, "It's nothing, the problem has been found, and data simulation should be fine."

As he said that, he typed the enter key with his right hand.

Data simulation videos are automatically generated, click to play.

Suddenly, Ning Xi's attention was attracted by the video.

In the video, there are countless metal picks on the x-18 hypersonic intercontinental missile body that look like fish gills, and a clear look of surprise appeared on her face.

Next, the real-time speed of the missile is displayed on the left side of the screen.

When the number jumped to Mach 49.7, Ning Xi's eyes suddenly widened, and his expression was full of disbelief.

"This, what is this?"

“The transformation result of air-driven.”

Ye Fan suppressed his helplessness and pointed to the computer screen and explained: "This design can minimize air resistance, and there are two small pushers installed under each metal paddle, which can increase the speed of the missile by about 70%.

"After calculation, the maximum speed of the x-18 hypersonic intercontinental missile can be infinitely close to Mach 50."

"Oh, I'm not asking."

Ning Xi waved his hand quickly and asked anxiously: "Brother, aren't you doing an air-driven simulation video? Why is it the final demonstration of the missile?"

"Does it mean..."

Her voice paused, and her eyes were filled with horror.

Final demonstration?

There is only one possibility!

Ye Fan nodded generously and admitted, "That's right, all 102 technical barriers have been broken through, and missile components can be designed tomorrow."

Even though Ning Xi was prepared in her heart, she was still scared after hearing Ye Fan's accurate answer.

From the beginning, Ye Fan said that he had to deal with air drive before zero, and he did not mention any of the 102 technical barriers.

I never thought that air drive was the last of 102 technical barriers!

this……

So terrible!!!

It has only been one month since the start of the X-18 hypersonic intercontinental missile.

To overcome 102 kinds of technical barriers in a month, you have to overcome at least 4 kinds a day.

But Ning Xi knew that Ye Fan had been checking various information for most of the past half month and had not taken action to overcome technical barriers.

To be precise, Ye Fan will definitely not exceed ten days to overcome many technical barriers!

Ten days?

102 technical barriers?

In other words, at least ten technical barriers must be overcome in a day!

Thinking about this, Ning Xi only felt her scalp numb.

She had probably seen about the 102 technical barriers that Ye Fan needed to overcome. Although the difficulty of each technical barrier is not as difficult as that of the autonomous track change trajectory, it is not much different.

After all, the x-18 hypersonic intercontinental missile weapon has completely surpassed the current technological limits of human beings.

Every technical barrier is a field that humans have never reached!

Notice the girl's dull gaze, Ye Fan raised his hand and shook it in front of him, "What's wrong?"

Ning Xi came back to her senses, and after a while, she said, "Brother is not a human!"

Ye Fan: “…”

Is the little guy scolding him?

Meeting Ye Fan's strange gaze, Ning Xi immediately realized the ambiguity in his words and waved his hand, "Brother, don't get me wrong. Xiao Xi is not scolding you, but praising you."

"Praise me?"

Ye Fan's expression became even more strange, "Xiao Xi, are you sure this is praising me?"

Ning Xi lit his head vigorously and said in a voice: "As far as I know, my brother started to capture various data from the beginning two days before I left the base, right?"

"right."

Ye Fan did not deny it.

Ning Xi asked again, "In less than ten days, my brother got all the technology needed for the x-18 hypersonic intercontinental missile. Is this something humans can do?"

"In my opinion, my brother is indeed not a human being, he is comparable to a god!"

"immortal?"

After listening to the girl's explanation, Ye Fan smiled playfully and tentatively suggested: "How about Xiaoxi call me the immortal brother in the future?"

"don't want!"

Ning Xi couldn't help but shivered, "What a stingy name, Xiao Xi doesn't want it!"

Ye Fan smacked his lips, but did not force it, his eyes fell on the computer screen.

The entire data simulation video was only a few dozen seconds long, but he was so excited!

Various simulated defense systems are ineffective in the x-18 hypersonic intercontinental missile.

No!

It should not be said that it cannot play a role, but it is helpless.

quick!

As fast as lightning!

After watching the complete data simulation video, Ye Fan felt a sense of pride.

Once the x-18 hypersonic intercontinental missile is launched, no matter which country or how strong the military power of this country is, it will have to be afraid of Xia State.

This unprecedented weapon represents too great strategic significance!

“So fast.”

Ning Xi's eyes were full of colors, and her jade lips were slightly pursed: "But there is still something missing."

Ye Fan's brows moved, "What's it?"

Ning Xi put his hands behind his back, leaned forward slightly, and said with a smile: "Brother is so stupid. Of course, he is an autonomous orbital change ballistic. Without this technology, he can only be called an intercontinental missile, not a hypersonic intercontinental missile."

Ye Fan laughed, "I was so busy that I forgot all such important things, I was guilty."

As he said that, he glanced at the time and changed his voice: "But there is no hurry to do this. It's not too late to do it tomorrow. Now there is a very important thing waiting for us to do together."

"What's up?"

"sleep."

Hearing this, Ning Xi looked a little unnatural and said shyly: "Brother, go to bed first. After sleeping during the day, Xiao Xi is not sleepy now."

"That won't work!"

Ye Fan shook his head and refused, regardless of whether the girl agreed or not, and directly hugged her and walked out of the laboratory.

On the way to the lounge, Ning Xi kicked her legs repeatedly, "Brother, I really don't sleep; and, my lounge is obviously there, why are you..."
