Cui Zuojing took down the knife on his back and handed it to Hades: "My knife is slightly damaged, can you repair it?"

Hades took a look and touched the only gap on the blade with his fingers: "Yes."

"That's good." Cui Zuojing was relieved, this is the best weapon shop on the top of the giant tree, and the level is not bad.

However, correspondingly, the fees are also very good.

Hades took the sample as large as the outdoor unit of the air conditioner for design testing, and the rest was taken back by Dong Zheng, and he would give it to him when he actually started working on it. He paid the deposit with the few remaining points, and the two went out through the back door. Ready to go home.

Sure enough, it was raining outside, but fortunately it wasn't too big, and it was nothing to the two of them. There is really no one on the street. On the empty street in the drizzle, Cui Zuojing sat in the back seat and hugged Dong Zheng, feeling the warmth from the other side, and suddenly felt indescribably comfortable and happy .

"Is it cold?" Dong Zheng asked him.

"It's not cold!" Cui Zuojing replied loudly, Dong Zheng's bike would definitely float into his eyes, so he raised his hand to cover his eyebrows to help him block it.

The lights elongated the shadows of the two of them, and then gradually shortened as they approached the next street light, repeating the cycle.

Parking the little pink sheep in Heimdall's backyard, Dong Zheng stuffed the car keys under the seat and sent a message to Beverley. After finishing the work, the car was also returned, and now I can open any door with Fu Zhe's key and go back immediately.

But Dong Zheng asked, "Do you want to go back?"

Cui Zuojing shook his head involuntarily. He and Dong Zheng hid under the wisteria trellis, holding one hand in his pocket to keep him warm. The windows on the topmost floor of Heimdall's main building were lit, which was Heinrich's office.

Cui Zuojing remembered that there was a similar place in his high school. It was regarded as a dating place for young couples. Every evening, the dean of the self-study class would ambush nearby to catch one or two unlucky couples.

He didn't experience the feeling of early love, and he didn't understand the ignorance and innocence that is unique to adolescence, but now, how to say, with a mature and stable person like Dong Zheng, he can often vaguely understand something.

Obviously both of them are no longer children.

"Where do you want to go to play?"

"Just sit here." Cui Zuojing sat down on the long stone railing and patted his side.

Dong Zheng sat side by side with him, the two of them held each other tightly, watching the rain rustling down, the rain hitting the leaves and making continuous pattering noises, and from time to time a particularly large drop of rainwater rolled down from the gap between the leaves and landed on the leaves. On the clothes, round dark marks are drawn.

For a while, neither of them spoke, not that they had nothing to say, but tacitly enjoyed the ambiguity that quietly rose in the tranquility.

This is a very suitable time for whispering, Cui Zuojing rubbed the callus on Dong Zheng's finger, "Have you ever been in love before?"

Dong Zheng thought for a while and said, "It's not a relationship, right?"

When Cui Zuojing heard that there was obviously a story, he immediately became interested: "How do you say it?"

"When I was fifteen or sixteen years old, I found that my orientation was a bit abnormal, and I kept hiding it. Later, when I went to study abroad, the atmosphere there was more open, and there were many male classmates who confessed to me. One of them felt good. I originally planned to After a while to see if it was suitable, I found out that he was playing in a mess." Dong Zheng faced the boy's curious eyes, paused, and continued, "Then I gave up, and it was from that time that I I found out that my mental cleanliness is quite serious, and after I return to China, I will never meet the right person."

"Then you've been single all the time?" Cui Zuojing glanced down, "You're 27 years old, you can't always use the left and right wives to serve you, right?"

"What does this have to do with age." Dong Zheng smiled, "I started my own business, and I don't even have time to eat or sleep when I'm so busy. I don't have time to think about anything else."

Cui Zuojing relented: "Then what about when you and your partners are having a dinner party? Those bosses will definitely play. I heard that you have almost no self-cleaning skills. Even if you don't want to, you can Someone must be rushing to post it."

"I'm not interested even if it's posted there. They all say that I have a mental cleanliness, not only for others, but also for myself, and after a long time, I really don't have much thought." Dong Zheng patted his head, " Take you as an example, you are considered to be as old as me, don't you use the same thing... left wife and right wife?"

Cui Zuojing muttered in a low voice: "We are different, you face more temptations than me, and I have always been sixteen years old, how can you be convenient."

Dong Zheng just laughed, and Cui Zuojing secretly jumped up in his heart when he saw that he didn't look like he was deliberately deceiving others in order to make him happy.

In fact, it is normal for adults to have emotional experiences in the world. Even lovers are not qualified to point fingers at each other's past. As long as they can guarantee their loyalty to the present and the future, they are already the most perfect.

But the feeling of "a certain person's past is blank without you, only you can leave traces on him" is so special, and all of Cui Zuojing's hidden possessiveness is suddenly aroused. He tightened his grip on Dong Zheng's fingers, and pretended to sigh, "Okay, although it sounds unreal, I'll just assume that what you said is true."

The topic was very cleverly stopped at the critical edge of some danger. For a while, neither of them spoke. The rain was getting heavier and the people around him were warm. Cui Zuojing emptied his mind and thought about nothing. The damp night wind, the pattering rain and the dim lights in the rain curtain.

He seldom had such an empty space. After arriving at the pure white world, he was swept up in the torrent called fate, and there was almost no time to stop and rest.

A huge drop of rain fell on the back of his hand, making him a little smart. Cui Zuojing looked down at the water marks on his hand, and suddenly felt a voice in his mind.

[so cute.]

Cui Zuojing:

It is actually difficult to distinguish the timbre of the voice that is directly ringing in his head, but Cui Zuojing still sounds like Dong Zheng.

He thought he had heard it wrong. After all, Dong Zheng didn't speak, and it didn't feel like this was how he conveyed information through Arabidopsis.

Dong Zheng looked like nothing happened, and Cui Zuojing really heard it wrong and didn't take it to heart.

But soon, he heard that voice again.

[If you kiss him now, what kind of expression will you show?]

Cui Zuojing was stupid.

He is now almost certain that it was Dong Zheng's voice. The young man turned his head to look at him, and Dong Zheng was staring straight ahead at the deserted street, looking very serious on the surface.

Cui Zuojing frowned suspiciously, and took the initiative to attack: "If you want to see what expression I will have, you will know if you try it? If you think about it, you won't come up with it."

Dong Zheng was stunned for a moment, he looked at the young man, obviously surprised at how he knew his inner thoughts.

Seeing his picture, Cui Zuojing knew that it was really Dong Zheng's idea, he took a deep breath, stood up suddenly and threw himself into his arms, and said loudly: "On the surface, he is so serious but he is thinking about such strange things behind his back. You are such a person!"

This time it was Dong Zheng's turn to be stupid. He hurriedly reached out and hugged Cui Zuojing, leaning back to avoid the punch of the teenager: "How did you know?!"

"Everything in your head has entered my head, how do you say I know!" Cui Zuojing punched Dong Zheng in the face, he didn't use any force at all, compared to beating Dong Zheng when the US and the Soviet Union were fighting for hegemony The nose bleed was madly spraying, and it was like scratching. Even so, he still felt distressed immediately, and quickly touched the bridge of Dong Zheng's tall nose, making sure that nothing happened.

Dong Zheng didn't feel much pain, he put his arms around Cui Zuojing's back to prevent him from making a fuss and falling, and defended: "But I didn't intend to pass it on to you at all."

Cui Zuojing stared at him for two seconds: "Liar, then how did I hear it?"

"Wait for me." There was some kind of guess in Dong Zheng's heart, he sank into the core, and at a glance he saw the light green font that was floating in the sky.

[Diffie-Hellman key exchange algorithm, under construction... ]

"Wait for you, why should I wait for you?" Cui Zuojing said confidently, "You secretly make up for bad things, and you still want to order me?"

After the young man finished speaking, he leaned over and kissed him loudly on the lips, and sat directly on Dong Zheng's lap. He got close, with a wicked smile, reached out and grabbed Dong Zheng's eyelashes.

This is…

Dong Zheng looked around the kernel. Before he noticed it, some unusual switches, ports and lines were quietly being built. Most of them were not yet completed, but according to the framework, they extended beyond the firewall to the outside world. connected.

Diffie-Hellman key exchange algorithm, an encryption protocol that allows two parties to jointly establish a shared key in an insecure communication channel without prior knowledge of the other party. This key can later be combined with a symmetric cipher to encrypt subsequent communications.

These lines, can be connected to other people's "ports" for communication

Dong Zheng's thoughts moved, and his thoughts flew along a line that had already been constructed, all the way to the center, and was received by Arabidopsis.

That string of thinking data is constantly changing, the public key that will enter the network transmission and the private key stored in the kernel will undergo complex changes to encrypt the information to ensure that apart from the two parties that establish the connection, there is absolutely no Others can intercept.

[can you hear?]

"Yes." Cui Zuojing put Dong Zheng's two eyelashes in the palm of his hand to observe, the shadow of the wisteria leaves fell on Dong Zheng's face, making his face extraordinarily deep, "Have you developed a new ability?"

[should be. ] Dong Zheng looked at the big characters "under construction", exited the core, and grabbed Cui Zuojing who was still pulling his eyelashes.

Cui Zuojing retracted his hand without incident, pouted and blew away the eyelashes in his palm. He hooked Dong Zheng's neck and looked down at him: "What kind of?"

"A communication function that should allow the team to communicate at the level of consciousness without communication tools and without speaking, but it has not been built yet. Let's test it later."

Is this the "gift" that Murphy calls it? Dong Zheng thought about it, seeing Cui Zuojing's fingers rubbing his lips thoughtfully, his throat suddenly tightened.

But this time, he didn't think about it anymore, and a kiss fell directly on the lips.

"Well!"

Looking at the subtle change in the young man's face that was caught off guard, Dong Zheng raised the corner of his mouth.

"As I imagined, this is the expression."
