"Everyone, go back to your study room!" A long, vicious instructor came over and scolded. I have been coming to this university for a long time, and their class is also equipped with a study room. The Department of Circle Science is different from other departments, and the management is more strict.

Like Cao Luo, they have to go to evening self-study every day, although there are no textbooks now, and most of them are playing with their mobile phones.

While walking, the fat man came over and muttered worriedly: "It looks very serious, otherwise it would have gathered before the military training officially ended." ”

Cao Luo didn't say anything, he already had a judgment in his heart.

At this time, Luo Xiaoyu came over, patted the fat man's shoulder with his slender hand, and said, "Classmate, me and I······ Well, this classmate said something. ”

Although the fat man is a little obscene, his ability is a little worse, but he still has a vision, seeing this scene, he immediately laughed ambiguously, and made an expression of "I understand, I will disappear immediately", Cao Luo was amused in his heart.

These classmates seem to regard Cao Chen as their sister and Luo Xiaoyu as their own······ Ahem, girlfriend.

Luo Xiaoyu burst out laughing and teased: "Your classmate is quite interesting." ”

Cao Luo said helplessly: "He's like this, there's no way." ”

Luo Xiaoyu put away his smiling face, looked around left and right, and after making sure that no one was paying attention to the movements here, he whispered, "Do you understand what the alarm just now meant?" ”

Cao Luo nodded, Platoon Commander He explained to them just now. Luo Xiaoyu said: "Because I am a member of the sophomore student union, I have access to this information. Just now it was an orange alert, that is, at the time of the alarm, there will be an orange light mist in the air, which is the alliance's sonic imaging technology. ”

Cao Luo was surprised, he really didn't pay attention just now. Luo Xiaoyu continued, "The orange warning means that the Apa army is invading our borders, and the situation is not promising. ”

Not optimistic?

Cao Luo muttered, for war, any defeat may cause a catastrophe, generally speaking, the country is accustomed to reporting good news and not bad news, and now this situation is mostly very serious.

"Sirens are usually only played in the military, but once they reach this level, they will have to be notified on a global scale, after all, we are all reserve forces of war." Luo Xiaoyu said very seriously.

Cao Luo understood that if there was any big defeat at the front, they would be sent up. All the boys signed up for military service, and when the alliance asked for it, they went into battle unconditionally to kill the enemy.

"The United States and the M National Front are almost unable to hold on, and their local students have begun to move forward in a planned way. And some small countries on the border, such as country R, have ······ Fell. ”

"Fallen?" Cao Luo is really surprised at this moment, not counting small countries for the time being, the strength of country R is not too weak, their samurai and ninjas have always been a well-known type of combat power in the world!

"That's right, now country R is asking for my country's assistance to rescue the people trapped in the local area and unable to escape as much as possible." Luo Xiaoyu said slowly.

Cao Luo had a bad premonition, and it was very strong, he looked at the girl in front of him, swallowed a mouthful of saliva, and asked with some uncertainty: "So what?" ”

"Brother." Luo Xiaoyu stopped, turned his head to look at Cao Luo, face to face, very serious.

"What are you doing?" Cao Luo was a little frightened, this feeling of fear had not appeared for a long time.

"I've signed up." Luo Xiaoyu said.

With a bang, Cao Luo's eyes darkened, and he staggered back a few steps, the expression on his face couldn't be described as complicated at all, it was simply hideous: "Who told you to report it!" You, you, you······"

Cao Luo stretched out his finger and pointed at Luo Xiaoyu, his fingers trembling and trembling.

Luo Xiaoyu said with some worry: "Brother, are you okay?" ”

Cao Luo came back to his senses at this time, his anger made his face flush, and he roared in a low voice: "When did you report it?" Who gave you permission to report? How did I not know you were going to report? ”

The three consecutive questions made Luo Xiaoyu a little overwhelmed, but she also knew that Cao Luo was worried about her, and a faint sweetness appeared in her heart after a long absence: "When the orange alarm just sounded, I knew the news." ”

Cao Luo was a little suspicious: "When the alarm just sounded? How do you know? ”

Luo Xiaoyu hurriedly explained: "I really just saw it, don't believe it!" ”

Cao Luo looked over and found that Hao Ran wrote a few big words on Luo Xiaoyu's mobile phone———— R country rescue registration.

"Why don't you discuss it with me first?" Cao Luo took a step forward, almost sticking to Luo Xiaoyu's face, and said viciously.

Luo Xiaoyu pouted: "It's because I know that if I tell you, you will definitely not let people report it, I really want to go, those people are trapped in the occupied area, and no one helps them, it's really pitiful." ”

Cao Luo looked at her sister who she hadn't seen for three years, she became more sensible and kinder.

"Forget it." Cao Luo sighed.

"Brother, did you agree?" Luo Xiaoyu said in surprise, a little incredulous.

"You've signed up successfully, I can't tie you up!" Cao Luo said angrily: "But it's ······"

"But what?" Luo Xiaoyu was still surprised in the previous sentence, but when she heard Cao Luo's "but", her heart was raised, and she didn't know what conditions her brother would make.

"But······ I'll go with you! Cao Luo said.

"What?" Luo Xiaoyu was dumbfounded, she didn't expect Cao Luoti's request to be this.

"What? No way? I'll tell you, with my experience and strength, it's okay to beat dozens of people like you. Cao Luo deliberately stiffened his face and scolded angrily.

"No, brother, I don't remember, you don't have a mecha yet, do you?" Luo Xiaoyu still understands Cao Luo's experience in the past three years, and his brother's strength is naturally undoubted, but without a mecha, he can't keep up with others in terms of survivability.

"Bring it." Cao Luo didn't argue anything, and it took a lot of effort to explain to this little girl, so he directly snatched Luo Xiaoyu's mobile phone.

"Alas, brother, what are you doing!" Luo Xiaoyu was completely subconscious, frowning, his cheeks bulging, and humming dissatisfiedly. After doing it, I was stunned to find that this was an action that I often did with Cao Luo when I was a child.

Big eyes secretly glanced in Cao Luo's direction, but Cao Luo didn't notice. He directly clicked on the registration interface, filled in all his information by two, and then submitted.

Suddenly————

"Count me in again." A small voice sounded, Cao Chen, she seemed to have been running for a long time, it seemed that her sideburns were loose, panting but determined.

Cao Luo looked at her deeply for a long time:

"Okay."
