"Lu Yang, can you still redeem the personal miniature air purifier?"

“…… Do I have enough tech now? ”

Xiao Ai's inquiry has almost become a daily task, and every day is almost like an alarm clock, asking out loud on time. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"Enough, 300 tech points for personal micro air purifier crafting technology, now the balance of tech points is 400 tech points"

Xiao Ai replied seriously.

"Uh, this technology seems to be rising a little fast?"

Lu Yang couldn't help but touch his nose and said.

"It's pretty fast, but there are many reasons," Xiao Ai nodded seriously.

Originally, it stands to reason that Lu Yang's remaining science and technology points should be in the thousands.

But that was before the exchange of the creature auxiliary combat suit, after more than two days, not only the creature auxiliary combat suit has been exchanged, but there are still four hundred remaining, which is already a terrifying growth rate.

This part is mainly brought about by the diffusion of knowledge abroad.

After a few days, the number of downloads and the number of online users in various countries have increased explosively.

This is mainly due to the attraction of Zhizhi's online translation and barrier-free communication.

However, because of this, this advantage somewhat obscures the role of Zhizhi itself, and he is abroad, more like a social software.

But...... As long as you can earn science and technology points, everything else is secondary to Lu Yang.

When the technology point reached 5,000 nodes, it was last night, when Lu Yang was sleeping.

Fortunately, it was when Lu Yang was sleeping......

Maybe it's because the five thousand technology points exchanged for it are really worth the money, so much so that this morning, when Lu Yang woke up, his head still felt a little up.

After reminiscing, I realized that there were many more things in my mind...... After recalling it carefully, it immediately became clear that it was the production technology of the bio-assisted combat suit.

……

When he knew that the extra knowledge in his mind was about the technology of making biologically assisted combat uniforms, Lu Yang understood that it was Xiao Ai who followed his orders and automatically exchanged such technology for the first time when the technology points reached 5,000.

However, because of Cao Guoyong's matter before, Lu Yang could only put this on hold for the time being, and at this time, in the taxi, when he heard Xiao Ai ask if he needed to exchange another thing, Lu Yang remembered.

"Redeem a personal air purifier ......" Lu Yang glanced at it, this has been delayed for so many days, forget it, just exchange it.

"Okay, then let's redeem it." Lu Yang nodded and said silently in his heart.

"Okay, Lu Yang, the exchange has been successful"

As soon as Xiao Ai's voice fell, the production technology related to the air purifier suddenly appeared in Lu Yang's mind, and he wanted to unseal the dusty memory from his mind, a sudden realization, a sudden enlightenment, and a feeling that something suddenly appeared in his mind, and spontaneously appeared.

But in the blink of an eye, Lu Yang mastered this related thing.

"These 300 science and technology points are not wronged, that is, they can be used to support environmental protection, or they can be used as the next product to bring some science and technology points to themselves."

Lu Yang smiled and muttered to himself.

However, now is not the time to think about this, the most important thing is my sister.

"Young man, the High School Affiliated to Peking University has arrived."

"Thanks, master, more money, no need to look for it"

"Young people nowadays, they're really generous......"

At the entrance of the High School Affiliated to Peking University,

Look at the luxury cars surging, the people in bright and gorgeous clothes, and then look at the scenery, which is so pure that it is a little lonely.

Lu Yang couldn't help frowning, and at the same time regretted it.

I obviously bought two cars, but because of the company, I didn't drive over, which ......

Forget it, my skills don't get home much anyway......

But...... didn't let her sister enjoy the treatment of a princess, which is really a little unwilling......

No matter how unwilling he was in his heart, his face was still full of smiles, and he walked up to his sister.

"Little beauty, can you enjoy the light and have a meal with this handsome guy?"

The little beauty wrinkled, "Phew! Shameless, handsome guy! ”

"But...... This beauty likes you to be shameless, let's go."

"Thank you, little beauty!"

"Get rid of the small print, huh!"

"Okay, my baby sister......"

……

The conversation between the two always surprises others who don't know the truth, and the brother and sister always leave the scene at this time, as if they have succeeded in a prank.

……

"Huh...... Stinky Luyang, aren't we going back to the rental house? Why get in a taxi? ”

"Didn't I mean to surprise you? You forgot? Lu Yang said mysteriously, "This surprise is not something you can show back to the rental house."

"That's right, smack! Call me brother! ”

"Hmph...... Stinky Luyang. ”

“…… Tell me, what's the surprise, a big meal? A day trip to the park, or ...... Hee-hee, a day trip to the amusement park is not going to the movies......"

"......" Lu Yang suddenly felt a little distressed when he heard this.

What is a sister? It should be used to care for it, and give it the treatment of a princess.

But before......

Secretly sighed in his heart, Lu Yang cheered up, and a mysterious smile appeared on his face, "The Buddha said: Don't say. This is already on the way to the surprise, you better wait," Lu Yang shook his head and said.

"Humph! Stinky Lu Yang, you don't even want to tell me this, you say, don't you love me anymore! ”

"Smack! Call my brother ......," Lu Yang said quietly.

"Hmph...... I don't, I'm biased, stinky Lu Yang, bad Lu Yang, you bully me, I'm going to cry, I'm going to cry! ”

“……”

"You don't say it, you don't say it, I scratch you, I ......"

Lu Hanyan threw himself into Lu Yang's arms, scratching Lu Yang's itches in various ways.

"You're still ...... Save it...... I won't tell you...... Hahaha... Ha ha...... Looks like I'm going to give you a good fightback! Let's take it! ”

"Hee-hee...... Hehehe...... Stinky Lu ...... Lv Yang, hee hee...... Don't scratch."

"Don't scratch it...... Laughing ...... Hee-hee, headache......"

As soon as the word headache came out, the movements on Lu Yang's hand suddenly stopped, and these two words stimulated Lu Yang's nerves, like a conditioned reflex, making Lu Yang instantly nervous.

"How's it going, where does it hurt, here, here? Or is it here? Lu Yang asked nervously and anxiously.

“……”

"Poof, I lied to you, hehe, stupid Lu Yang!"

"Wow! Dare to lie to me, see if I can't clean up your girl......"

Lu Yang breathed a sigh of relief in his heart, and he was about to scratch, but his movements were much more careful than before......

In the taxi, there was really laughter, which attracted the taxi driver to shake his head: "Now the little couple, I just know how to play, think about how I was at that time, think about ...... at that time"
