My sister has really grown up, and Cao Luo, who is an older brother, is all pounding, especially the blushing face, the hot breath exhaled from the murmuring, and the still slightly tired eyes······

Ah~ I can't look at it anymore, this little girl is really not worry-free.

Don't look over, Cao Luo said: "Xiaoyu, do you remember Lao Cao?" ”

"Old Cao?" Luo Xiaoyu perked up: "Of course I remember, I just said that something seems to be missing, where is he?" Why didn't I come back with you? ”

Cao Luo was silent for a while, and said, "Old Cao used all his energy to save me before, and now he ······ Slept. ”

Luo Xiaoyu didn't know what to say, Lao Cao was very kind to Cao Luo, that was to give him another life! Luo Xiaoyu was also very familiar with Lao Cao before, and this old man often teased Luo Xiaoyu, who was prone to a small temper.

But now, everything has changed, he is no longer as brutal as he was then, Cao Luo is no longer simple, and the old Cao ······ is already asleep, looking at Cao Luo's expression, it is not a simple matter.

"What can I do?" Luo Xiaoyu asked softly.

"Will you use the circle to activate the energy crystal?" Cao Luo asked with some expectation.

"Nengjing? Brother, you can get this kind of thing, but I don't have the transformation circle of energy crystal, I heard that only Dr. Lan ······" Before he finished speaking, his mouth opened wide in shock.

On Cao Luo's mobile phone, there is a complex magic circle suspended, others don't understand, but Luo Xiaoyu is a high-achieving student of the magic circle, and he can see the effect of this thing at a glance.

didn't see anything outside, he came directly to Cao Luo, grabbed Cao Luo's arm, and looked at this magic circle motionless with big eyes, the eagerness of his gaze was simply chilling.

At this time, Cao Luo had another feeling, his sister had a fragrant fragrance, which was irresistibly drilled into her nostrils, coupled with the large-scale figure clinging to her body, which made people feel uneasy.

Cao Luo swallowed several mouthfuls of saliva, this little goblin, don't you know that my brother is very uncomfortable? His whole body is stiff now, and he is afraid that if he moves, his sister will mistake him for a hooligan.

Luo Xiaoyu watched it for ten minutes before he reluctantly took his eyes off the magic circle, and couldn't stop saying from his mouth in amazement: "It's so subtle, how did he come up with this structure······ It turns out that the use of spiral connection in this kind of place will have the effect of energy absorption······"

Well, as Cao Luo, who has never taken a magic circle class, what kind of magic circle structure, spiral connection, listening to this is a big head, I only know that it seems to be very powerful, as for the usage······ He wants to know, is it still possible to pick up Luo Xiaoyu in the middle of the night?

"Xiaoyu, you mean, you'll use it?" Cao Luo asked eagerly.

"Of course!" Luo Xiaoyu looked very proud: "I am a graduate student who was personally booked by Professor Qian Xuedong of the Law Circle Department. ”

Booking ······ The current professor, have you fought so hard to fight for a good seedling? You know, Luo Xiaoyu has just entered his sophomore year.

"Look at me." Luo Xiaoyu took out his student ID card from his body, and posted it on the door of the experimental building, only to hear the sound of "dripping ————", the door opened, and Cao Luo followed Luo Xiaoyu and went in.

As soon as he entered, Cao Luo's eyes were straight, and in front of him was a huge hall, and in the middle of the hall was a large sand table, on which was a miniature model of the exquisite Alliance Research University. There are several elevators around the lobby marked "A", "B", "C", and "D".

Luo Xiaoyu took Cao Luo from the "B" elevator to the underground.

There was no one at this point in the laboratory, and the corridor was also dark, and only the sound of walking could be heard, and the voice-activated lights would light up without warning, and the walls would be miserable and white.

Obviously it was underground, but he always felt a cold wind blowing on his body, Cao Luo obviously felt that the girl next to him unconsciously grabbed his clothes, and his body fell half a step behind him.

Cao Luo smiled: "How old are you, are you still afraid of this?" ”

Luo Xiaoyu glared at him with some embarrassment: "I want you to take care of it!" ”

Cao Luo said with a smile: "Which laboratory shall we go to?" ”

“B103。” Luo Xiaoyu replied.

"Good!" Cao Luo didn't have any prior declaration, he directly hugged Luo Xiaoyu as a princess, put her pretty face on his chest, took a deep breath, accelerated violently, and rushed to the laboratory.

Luo Xiaoyu first exclaimed, and then calmed down, she remembered that Cao Luo was like this when she was a child, once she was afraid of the dark, he would hold herself like this and turn his face to his chest.

This embrace, even after so many years, has always been there and has always been so warm.

Until the laboratory, Luo Xiaoyu was still motionless in his arms, and Cao Luo patted Luo Xiaoyu's buttocks with some amusement: "Don't pretend, it's all here, come down, how old are you still like a child." ”

These two slaps made Luo Xiaoyu's face bloody, and she didn't know how many times she had blushed tonight.

Hurriedly climbed down and glared at Cao Luo angrily: "Don't disturb me, I'm going to activate the magic circle!" When Cao Luo heard this, he immediately shut up.

Luo Xiaoyu took a deep breath to calm down his mood, his eyes became serious, he closed his eyes, and went through the magic circle that he had just figured out in his mind, and his hands were already on the operating table.

"Brother, where did you put Lao Cao?"

Cao Luo hurriedly took out the ring where Lao Cao was stored, Luo Xiaoyu took it and put it on a small platform in the center of the console.

"Nengjing also take it out."

Cao Luo took out the energy crystal, and Luo Xiaoyu handled the energy crystal a little, and fixed it in a small hole on the small platform.

Pick up a special brush from a box and tap the table with the other hand, and you can make a brilliant and magnificent sparkle. Immediately, a fog appeared over the console like a bright starry sky. Luo Xiaoyu's expression was very focused, and the pen in his hand guided back and forth in the fog, outlining and drawing.

The basic prototype of a circle took less than two minutes, which is the easiest. The most important thing is the construction of the internal structure of the circle.

Sure enough, at this point, Luo Xiaoyu's movements immediately slowed down, and his eyes, which were originally closed, also opened, staring closely at the magic circle in the air. Luo Xiaoyu didn't directly enter the magic circle given by Lan Lan into the pen and get the results directly, because he was afraid that the data would be found by others and cause trouble to the two of them.

When she was writing for about ten minutes, Luo Xiaoyu was obviously a little physically exhausted, she was not the kind of girl who loved sports, she was mostly theoretical research on weekdays, and there were not many opportunities to write such a complex magic circle in person.

The big arm was sore, but Luo Xiaoyu didn't dare to stop, the most taboo thing about this kind of magic circle writing was to pause, it was easy to dissipate cleanly in a short period of effort.

Gritting her teeth, when she was about to endure it, a pair of big hands stretched out from under her armpits and held her big arms, and Cao Luo's voice sounded from her ears: "You girl, just say it when you're tired, don't hold it hard." ”

With this borrowing point, Luo Xiaoyu felt a lot more relaxed, although the posture of the two of them was more like hugging each other now, but surprisingly, this time Luo Xiaoyu did not blush, but felt a trace of sweetness of being cared for.

Twenty minutes passed, and as Luo Xiaoyu's last stroke fell, the complete magic circle was full of light, and Luo Xiaoyu picked up the primary scroll on the shelf on the side and covered it.

After a full five minutes, Luo Xiaoyu carefully turned the scroll, and there was a magic circle clearly printed on it, and this magic circle was still slowly rotating as if it was alive.

"Fortunately, I didn't disgrace my life." Luo Xiaoyu breathed a sigh of relief, a bright smile appeared on her face, and Cao Luo gave a thumbs up like a girl without hesitation.

"Then it's easy." Luo Xiaoyu aimed at Lao Cao's ring, and the scroll in his hand was torn open with a click.

The dazzling light instantly enveloped the room, and Cao Luo sealed the window with golden liquid in time to prevent the strong light from shining on others.

The ring shone brightly, a golden light that Cao Luo was once very familiar with, and it lit up from the ring. Cao Luo's expression became more and more excited, and his heart disease for many years finally had a chance to be lifted.

As if dragged by some force, the ring hung in mid-air, and above, a mass of air slowly converged.

Inside the house, the brother and sister were staring at the air current. I saw that this little guy was very unstable, like a candle that could be extinguished at any time, trembling and terrifying.

I don't know how long it took, but while the two of them were waiting, the "air current" finally converged into a human figure.

"Yay!" Cao Luo waved his hand excitedly, but was beaten by Luo Xiaoyu angrily: "Brother, don't be like this, the magic circle has not completely stabilized yet, and you are so easy to give up!" ”

Cao Luo's movements stopped abruptly, smiling wryly, but he didn't dare to make other moves.

Luo Xiaoyu covered her mouth and smiled, in fact, she was lying to Cao Luo to play, if the magic circle is so disordered, what qualifications does it have as the main direction of scientific and technological development now? Who let this bad guy hurriedly disturb people's dreams without even saying hello, and he deserves to scare him!

At this moment, the human figure became clearer and clearer, more and more condensed, although Cao Luo still didn't dare to move, but his expression was getting more and more excited, he could already see Lao Cao's appearance, still that familiar look.

Lao Cao's expression was very solemn, his eyes were tightly closed, but under the effect of the scroll, his eyes were moving. Cao Luo held his breath, he felt that even in the face of Saint-level Apa, he had never been so nervous. It was a feeling that I didn't even dare to gasp for air.

In Cao Luo's expectant gaze, Lao Cao's eyes opened!
