After handing in the system, I became a national treasure by robbing supplies

Luo Xu cleared her throat and shook her head, "No, there is currently no possibility of directly manifesting scientific instruments, but... even the laser cannon has been directly embodied. Maybe a particle can be embodied next time.

Collider."

Liu Geng became even more excited, "Haha! That's great!"

"I hope you can search more in other worlds to see if there are any better resources."

After discovering that it was possible to create a particle collider, Liu Geng became more and more enthusiastic about Luoxu.

Their working place is deep underground, and the defense here is so tight that not even a mouse can escape.

Liu Geng took her and explained to her in detail the functions and operation methods of these instruments one after another.

Luo Xu listened carefully. With her current brain expansion and expansion level, she could achieve the state of photographic memory.

Immediately afterwards, her ‘ability’ index continued to soar.

[Abilities: Scientific Research Technology (70-51-72/100) Construction Technology (11/100) Combat Technology (16/100) Knowledge Ability (51-52/100)]

The elevator continued to go down until it reached the thirty-sixth floor underground. The temperature here is extremely low and it is also one of the national key research projects.

Luoxu looked at them one by one.

In fact, the country had built such a huge project many years ago, and even now it is still a secret project.

If she had not handed over the system to the state, she would not have been able to touch these areas.

Listening to Liu Geng's explanation, Luo Xu memorized it carefully. Suddenly, a system prompt sounded in his mind.

[Level 1 warning! There is a flaw in the Level 2 shelter!]

[Warning! Warning! Dangerous loopholes in secondary shelters! Please solve it as soon as possible, otherwise the shelter protection index will continue to decline. 】

The sound was harsh and made Luo Xu's head buzz.

It starts again!

Secondary shelter?

There are thousands more people there!

Luo Xu's expression suddenly changed. She quickly took out her cell phone and found that there was no signal at all. She grabbed Liu Geng's arm and said, "I'm in a hurry. Take me up quickly. I want to practice with Uncle Wei."

Liu Geng was stunned, "What?"

"Ask me later, take me up quickly, it's urgent!"

"good."

After going up, Luo Xu quickly contacted Wei Zheng and explained the system prompts.

Without any delay, Wei Zheng immediately ordered the helicopter pilot to turn around and go back.

He contacted the central command post immediately.

The staff who received the call were a little confused.

"But, sir, we didn't find anything unusual under our surveillance. I wonder where did you get the news, sir?"

"Check! Now, contact all secondary shelters." Wei Zheng said sharply.

"yes!"

Wei Zheng never doubts the system's prompts.

In an instant, many military personnel were dispatched from the base and headed towards the secondary shelters in various areas.

Luo Xu also rushed to the central command center as soon as possible. There was a trace of tension in the orderly atmosphere here.

Ever since the system gave a warning before, it has been quiet. Until now, there has been no movement at all, and I don't know what happened.

Fortunately, there is no system prompt now, which is a good thing.

At this time, all secondary shelters sounded the alarm.

When Luo Xu arrived, Wei Zheng and several of his commanders were constantly making phone calls to confirm the situation.

After about ten minutes, Wei Zheng turned around and walked out.

Seeing Luo Xu, he frowned slightly, "Why are you here? Why don't you go back quickly?"

"It's too dangerous here."

Luo Xu looked solemn and shook her head, "Uncle Wei, do you know where the problem is? I want to go over and have a look."

Wei Zheng really had a headache, "This attack is definitely not an accident, it must have been deliberately planned. You are the most important to us, and I have to take the lead in ensuring your safety."

Luo Xu took a deep breath, "But Uncle Wei, I can't always be under your protection and do nothing."

Unable to defeat her, Wei Zheng had no choice but to have the helicopter prepared.

"Okay, you join the second special operations team and follow me to solve the problem together."

Luo Xu followed Wei Zheng, and soon several staff members came over with body armor and other protective equipment, and they put them on Luo Xu in an orderly manner.

When Luoxu arrived at the place where she boarded the helicopter, her weapons and equipment were ready, and several team members were waiting for her.

Except for Ju Chen, she didn't know any of the team members who came this time.

"Quick, get on the plane, we are on a rescue mission this time."

"Shelter No. 4 is completely out of contact now, and we are implementing manpower rescue."

Ju Chen stood on the plane and stretched out a hand towards Luo Xu, "Come on, sir, you want me to protect you."

Luo Xu also got on the plane. Wei Zheng gestured to her and got on another plane.

On the plane, the team leader explained the plan to the seven people.

"There is a problem in the secondary shelter. We have been unable to contact you for more than fifteen minutes. We suspect that a tragedy is very likely to occur. You should all be mentally prepared."

After saying that, he turned to look at Luo Xu, opened his mouth, and his voice was a bit colder.

"Ju Chen, protect her."

"yes!"

Ju Chen raised his head and took a sip of wine, then handed the wine bottle in his hand to Luo Xu.

Luo Xu waved her hand, "Did you know that the last accident at that base was related to a mutated zombie?"

As soon as these words came out, several other team members also looked at Luo Xu.

Such a look was a little weird, and Luo Xu didn't know how to speak when the words came to her lips.

Ju Chen frowned slightly, "This zombie is very dangerous."

Luo Xu nodded, "It is said that it is invulnerable, so I specially prepared some cold weapons."

While several people were wondering, Luo Xu distributed the swords, daggers, and Tang knives he took out from the system to everyone.

Although they have been exposed to cold weapons, they rarely use them now that they have guns.

Now playing with the weapons in his hands, the captain frowned and said: "The guns we have are enough for us. We don't need these. Carrying these things with us is just a drag."

Luo Xu said seriously: "Believe me, I have faced those kinds of zombies head-on. I know very well where their weak points are. In close combat, our reaction speed when shooting is far less than the speed at which they can draw out their claws."

Ju Chen shrugged, "She has indeed faced off against that kind of zombie. I believe her words."

Only then did a few people pay attention. After a moment of hesitation, they put the sword away.

Ten minutes later, their helicopter arrived directly above their destination.

Below is the secondary shelter that fell into a state of dead silence.

All the lights in the shelter were turned off, and no one knew what was going on inside.

Wei Zheng was in the helicopter in front, using the intercom to warn several people, "Be careful. No matter what, you all come back alive!"

At the end, he yelled again, "Especially Luoxu, come back alive!"
