Since returning from Longyuan Mansion, Ye Fan has been staying in the room, with dozens of pieces of information brought back on the table in front of him.

That is the technique that Ye Fan needs to overcome next.

Supersonic missile-warhead cooling system!

After reading this document, Ye Fan checked a lot of information on the Internet and was also clear about the difficulties and functions of this technology.

Simply put, it is to cool down the warhead of the supersonic missile.

Generally, the speed of a supersonic missile is at least Mach 5 or above. Only by crossing the Mach 5 h can it be considered a real supersonic speed.

When the missile warhead is flying so fast, the surface temperature will reach an extremely high level, especially the warhead part, which is even more terrifying.

After compiling all the data and information, Ye Fan calculated the temperature results that the warhead surface metal can achieve when the fastest speed of the x-17 supersonic missile is.

3400 degrees!

It's so scary!

This temperature is not only extremely harsh on the material used to make the warhead, but the most important thing is the cooling system.

If the cooling system is not good, even the best metal material cannot hold on!

The existing cooling system is not enough to support the needs of the x-17 supersonic missile, so a new cooling technology must be developed to deal with the high temperatures generated by the x-17 supersonic missile after it is launched.

After nearly two hours, Ye Fan put away all the information in front of him and left the villa alone.

It was past four o'clock in the afternoon.

"Ding Dong--"

Ning Xi, who had been waiting in the living room, heard the doorbell and trotted to the door. When she saw the person outside the door, she smiled happily.

"Yu Meng, Ke Ke; I miss you so much."

As soon as the door opened, Ning Xi was excited to give the two girls a hug, but before she could hug her, the two girls dodged and dodged as if they had agreed.

Ning Xi, who had been thrown into nothing, stood there in a daze, looking at the two women in confusion, "What are you hiding?"

Luo Yumeng raised an eyebrow at Su Ke, "Ke Ke, this young lady didn't realize her mistake at all. What do you think should you do?"

Su Ke had a straight face, "What else can I do? Of course, it is to punish her!"

"How to punish?"

"How do you say you're punishing me? Of course, I'm stripping her naked!"

When he heard this, Ning Xi was so scared that he stepped backwards, with his hands on his chest, and his eyes looked alert: "Don't do anything nonsense, and what am I doing wrong?"

Su Ke held his forehead and said helplessly: "Xiaoxi, you have reached this point. You don't know what you did wrong. You really don't know what to say about you."

"that is!"

Luo Yumeng stared at her eyes angrily, "I used to call you Miss Ning, but I didn't expect you to be Miss Ning. I saw you sitting on the floor in a post-match interview video online for an hour!"

"Su Ke followed and agreed, I was not much better either."

Finally, the eyes of the two women fell on Ning Xi and said in unison: "Ning Da Qianjin, the richest daughter!"

At this point, Ning Xi finally understood what the two women were talking about, lowered her head guiltily and explained weakly: "Yu Meng, Ke Ke; I really didn't mean to hide this from you, it was my father's request."

"Then why don't you explain to me and Ke Ke after you announce your identity, and still treat us as good friends?"

Faced with Luo Yumeng's questioning, Ning Xi nodded repeatedly, and said in a very affirmative tone, "Of course you are my good best friends and the best friends!"

Su Ke raised her eyebrows and said, "Just just now, let me explain the issue of Yumeng."

Ning Xi had a bitter face, "I've been very busy lately, I forgot."

After saying that, she secretly glanced at the two girls, her thief-like little look was extremely cute.

Luo Yumeng could no longer pretend and bent her waist with a smile, "Ke Ke, I really can't stand Xiao Xi's pitiful look, who can't tell her?"

Su Ke rolled her eyes, "Look at what you said, do you think I am willing to say Xiaoxi? It's all about cooperating with your plan!"

"Hey, you traitor!"

"A traitor is a traitor. If it is for Xiaoxi, it is not impossible to be a traitor."

"Ok, you won."

Seeing the two of them looking like this, Ning Xi secretly breathed a sigh of relief.

The next second, she was sandwiched between Luo Yumeng and Su Ke, and then she was held away from the ground and walked towards the villa.

"What are you two doing? Let me down quickly."

On the sofa in the living room, Luo Yumeng and Su Ke looked at each other and threw Ning Xi on the sofa.

Ning Xi simply pretended to be ruined and lay motionless on the sofa, "I was wrong, please forgive the little girl's fault."

"For the sake of your call me a fairy, I won't bother with you, the little girl."

Luo Yumeng smiled happily.

Su Ke nodded with a smile, "Please... forgive you."

"Thank you for not killing the two fairies!"

In the next time, Ning Xi took the two girls around the house, and the final stop was her bedroom.

"Wow, how great would it be if my family was like this!"

Luo Yumeng lay on Ning Xi's bed, feeling the softness under her body, and enviously said: "If my bed was so soft, I could stay with the bed for a year!"

Su Ke smirked and pulled Ning Xi to sit beside the bed, "Xiao Xi, why didn't you see Ye Fan? Didn't he live in your house?"

"yes."

When he mentioned Ye Fan, Luo Yumeng's eyes lit up and she sat up suddenly, "Where is the handsome guy Ye? Call it out quickly and enjoy it for us to be so beautiful. Xiaoxi can't hide the charm of the golden house!"

"Pooh--"

After being teased by her best friend like this, Ning Xi's cheeks turned red and she glared at her shamelessly, "What a golden house that hides a charm, nonsense!"

"Damn!"

Luo Yumeng widened her eyes and stared at Ning Xi in surprise, "Can you blush like this kind of words make you blush? Xiaoxi, why are you still as unsatisfied as before?"

As soon as these words came out, Ning Xi's face turned redder.

Su Ke watched from the side and laughed constantly, and added appropriate comments: "Xiaoxi, Yumeng is right. Logically speaking, you and Ye Fan have been dating for so long, and you should have broken through that step long ago. What else can you be shy about?"

"I……"

Ning Xi was about to explain, but was interrupted by Luo Yumeng, who was determined to eat melons. She pulled Ning Xi's little hand, and a thick gossip fire burned in her eyes. "Tell me honestly, who was on it when you and Ye Fan were there?"

Hearing this, Ning Xi's pretty face was quickly congested. At this moment, she just wanted to find a crack in the ground to get into it.

What kind of best friend are these?

Ke Ke is better...

Su Ke made a gesture to cover his ears, but his ears were exposed from his fingers, and his eyes were full of curiosity, "Wow, can I hear this without recharging money? So... Xiaoxi is on top or down?"

Ning Xisheng hung his head with no desire.

have to!

When she didn't say it, this wasn't a good thing either!

Meeting the eyes of the two women, Ning Xi gave them a broken mind with anger, "What are you talking about? My brother and I have confirmed the relationship between us, but it is just a relationship. It is impossible for that kind of relationship to have before we get married!"

"ah?"

Luo Yumeng opened her mouth wide and said in disbelief: "Xiaoxi, can you say that you haven't slept together yet?"

Ning Xi covered her face, "…I slept, but I just slept and did nothing."

"impossible!"

Luo Yumeng shook her head arbitrarily and rejected, "As long as you are a man, you can't stand it in the same bed with you!"

Su Ke nodded in agreement, "Unless... Ye Fan is not a man!"

Luo Yumeng responded, "Or, Ye Fan has a problem with that!"

Ning Xi: "…"

Who will save her?
