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 no possibility of directly manifesting scientific instruments, but... even the laser cannons have been directly manifested, maybe next time a particle will be manifested Collider."

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

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

After discovering the possibility of a particle collider, Liu Geng became more and more enthusiastic about Luo Xu.

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

Liu Geng took her one by one to explain the functions and operation methods of these instruments in detail.

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

Immediately afterwards, her 'ability' index continued to soar.

【能力：科研技术（70-51-72/100）建筑技术（11/100）格斗技术（16/100）知识能力（51-52/100）】

The elevator kept going down until it reached the 36th floor underground. The temperature here is extremely low, and it is also one of the national key research projects.

Luo Xu looked at them one by one.

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

If she hadn't handed over the system to the country, she wouldn't be able to touch these areas at all.

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

【Level [-] Warning!There is a flaw in the secondary shelter! 】

【warn!warn!Dangerous loophole in the secondary shelter!Also ask the host to solve it as soon as possible, otherwise the protection index of the shelter will continue to decline. 】

The harsh sound made Luoxu's head buzz.

Start again!

Secondary shelter?

There are still thousands of people there!
Luo Xu's face changed instantly, and he quickly took out his mobile phone, but found that there was no signal at all, so he grabbed Liu Geng's arm and said, "I'm in a hurry, take me up quickly, I want to practice Uncle Wei."

Liu Geng was taken aback, "What?"

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

"it is good."

After going up, Luo Xu quickly contacted Wei Zheng and explained the system's prompt.

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 got the call were a little confused.

"But, sir, under our surveillance, we didn't find anything unusual. I don't know where you got the news from, sir?"

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

"Yes!"

Wei Zheng never doubted the system's prompts.

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

Luo Xu also rushed to the central command center immediately, and there was a trace of tension in the orderly atmosphere here.

Since the system gave a warning before, it has been subdued. Until now, there is still no movement, and I don't know what happened.

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

At this time, various secondary shelters sounded the alarm.

When Luoxu arrived, Wei Zheng and several of his commanders were constantly calling 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 soon?"

"It's too dangerous here."

Luo Xu looked serious and shook her head, "Uncle Wei, do you know what's wrong? I'm going to have a look too."

Wei Zheng really had a headache, "This attack was definitely not accidental, it must have been planned deliberately, you are the most important thing to us, I have to take the lead in ensuring your safety."

Luo Xu took a deep breath, "But Uncle Wei, I can't just stay under the protection and do nothing all the time."

Really unable to hold her back, Wei Zheng had no choice but to get the helicopter ready.

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

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

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

Among the team members who came this time, except for Ju Chen, she didn't know the others.

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

"Shelter No. 4 is completely unreachable now, and we are implementing human rescue."

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

Luo Xu also boarded the plane, Wei Zheng gestured to her, and boarded another plane.

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

"There is a problem in the second-level shelter. It has been more than 15 minutes and we have not been able to contact you. We suspect that there is a high possibility of a tragedy. You should be mentally prepared."

After speaking, he turned to look at Luo Xu, opened his mouth, and his voice was a bit cold.

"Ju Chen, protect her well."

"Yes!"

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

Luo Xu waved his hand, "Do you know that the last accident in that base had something to do with a mutant zombie?"

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

This look in his eyes was a little weird, making Luo Xu not know how to speak when the words came to his 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 at hand."

While several people were wondering, Luo Xu distributed the long sword, dagger, and Tang knife that he had taken out of 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 weapon in his hand, the captain frowned and said: "We have guns that are enough, we don't need these, these things are just a drag."

Luo Xu said seriously: "Believe me, I have fought with that kind of zombies head-on, and I know exactly where their culprits are. In close combat, the reaction speed of our shooting is far less than the speed of their claws."

Ju Chen shrugged, "She did face-to-face with that kind of zombie, believe her words."

Only then did a few people pay attention, and after a moment of hesitation, they still put away the big knife.

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

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

The lights in the shelter were all extinguished, and no one knew what was going on inside.

Wei Zheng was in the helicopter in front of him, using the walkie-talkie to tell a few people, "Be careful, no matter what, you all come back alive!"

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