However, some plans still need to be prepared early.

Chen Zheng was still a little hesitant, should he give Li Ying a set of swallowtails? It’s not that Chen Tianshang was reluctant to let it go. The key issue is that the origin of the swallowtails is difficult to explain. Chen Zheng did not want to disclose the existence of the Civilized Library, so he will now reveal it to Li Ying, because this hero will only cause trouble to her.

Aunt Li is just under her nose. As long as she makes some preparations, her safety will be worry-free.

Chen Zheng put down the book, took out a piece of white paper, and wrote and painted it on it. To ensure safety, it is necessary to monitor the entire Zhongjing City.

The surveillance system of Zhongjing City has greatly increased its expenses in recent years, and there are more cameras on the street. If Chen Zheng is willing, he can completely connect the swallowtail to it.

But this is not very safe. No matter how secret it is, there is always a chance of being discovered. The best way is to build a monitoring system covering Zhongjing City by himself. Your own things can be used with confidence and reliability.

"It's just that, I rely too much on the processing center in the library, which is too unfavorable for my future development! Damn, what's going crazy about the US Alliance? Why do I fight against the Empire? The Empire hasn't done anything out of the ordinary in recent years!"

If you want to achieve Chen Zheng’s ideal monitoring status for Zhongjing City in his mind, it is necessary to use the machining center, which is something he is unwilling to do.

Chen Zheng has not yet figured out all the techniques used by the swallowtail in his hand. If he has another monitoring system, he will not have to learn new technologies in the next few years. If something unexpected happens later, Chen Zheng's original intention will be completely destroyed and he can only rely on civilized libraries.

After Chen Zheng obtained the Civilized Library, his purpose was to learn knowledge from it and turn the things in the library into things that are in his own hands.

Instead of simply turning the civilized library into a rigid tool.

"It would be great if Yingzi was willing to return to Zhongjing City to develop, that would be great!" Chen Zheng thought so. If Li Ying was willing to return to Zhongjing City to develop, the two of them would probably have been married long ago at this time. If they worked harder, they might even have children.

After thinking about it, Chen Zheng made up his mind to build the monitoring system. "Even if the Civilization Library disappears, this system is still in his own hands, and there is still time to study it!"

When querying the technology for manufacturing dovetails from the Civilization Library, Chen Zheng once saw a monitoring technology that is very suitable for his current use. It is an all-terrain reconnaissance device, a reconnaissance ball that can cover an area of ​​ten square kilometers. In this area, the reconnaissance ball can penetrate buildings and scan a space of one hundred meters underground.

What’s important is that this reconnaissance ball has a diameter of only 20 centimeters. Its own gravitational field system can allow it to suspend at a height of one thousand meters. The invisible system is the only one that makes the radar on the Sky Star unable to detect it.

It can be said that it is the most suitable thing for Chen Zheng's requirements. It only takes fifteen to cover the main urban area of ​​Zhongjing City. When it needs to be expanded, it can also raise the reconnaissance ball to a higher height. Although the scanning accuracy is reduced, the scanning area has been expanded.

Moreover, Chen Zheng has studied the data on reconnaissance balls. Even if it rises to a height of 10,000 meters, the so-called accuracy decrease is several levels higher than the resolution of the most advanced spy satellites in the three powerful countries.

"You're the one!" Chen Zheng decided to create the reconnaissance ball at night and then launch it into the air. The question now is, is the basic elements required for this machining center or the top of the fish tank?

Think about it, even if the fish tank is, I didn’t know why I was so crazy. I thought there was a fish tank. The basic elements were not simple. If you really connect to tap water, you would have as many basic elements as possible!

Chen Zheng couldn't understand what this basic element was. Just in case, he didn't decide to buy some common metals such as iron, copper, aluminum and other metals into the Civilization Library just in case.

So, after lunch, Chen Zheng drove Li Ying's car to the warehouse gathering area in Nanxiao. A piece of metal ingot weighing 100 kilograms came.

When Chen Zheng parked the car downstairs, he unexpectedly found that Uncle Wang was wandering downstairs.

"Uncle Wang! Are you here to find Aunt Li?" Chen Zheng asked when he opened the car door.

Unexpectedly, Uncle Wang was full of anxiety and stepped forward and grabbed Chen Zheng's hand: "Xiaozheng, go to the hospital quickly. Your Aunt Li fainted on the street just now!"

Chen Zheng fainted, and Aunt Li fainted? She has always been healthy. She had just had a physical examination not long ago. Everything was normal. How could she faint?

After pulling Uncle Wang into the car, Chen Zheng took him to the hospital.

"Uncle Wang, how did Aunt Li faint? Her body has always been very good!"

"Hey, I don't know what's going on. Your Aunt Li and I went to the elderly activity center in the neighborhood to rehearse the program. On the way, we met a man and a woman holding a map to ask for directions. Who knew she suddenly fainted. I went to your bookstore to find you. You were not here, and you were not here at your house."

"Just thinking about you going there, you are back!"

After hearing Mr. Wang's words, Chen Zheng felt cold: "Have you met someone asking for directions? Are you from other places or foreigners?"

"Hey! Xiao Zheng, how do you know that you are from a foreigner? We didn't want to pay attention to them, and we didn't know how to speak foreign languages ​​either! But when they came up, they just pointed out the way. Who knew that your Aunt Li fainted!"

"Where are those two foreigners?"

"Watch it in the hospital! Otherwise, how could I run back to find you?"

"It's so fast!" Chen Zheng said in a low voice.

"Xiao Zheng, what did you say? What did you come so quickly?"

"Nothing, I mean I'm going to drive faster!"

"Hey, Xiaozheng, don't worry, your Aunt Li has been sent to the rescue room."

"Thank you, Mr. Wang!"

"What are you grateful for? I've been a decades-old neighbor! Why did you think your Aunt Li faint?"

Soon, Chen Zheng drove to the hospital.

As expected, the two foreigners were gone, and the doctor happened to come out of the emergency room, "Who are you family members?"

Chen Zheng took a step forward: "I am! The patient is my girlfriend's mother. My girlfriend can't come back in Kyoto for a while, I can make the decision!"

The doctor breathed a sigh of relief, "You can make the decision. In addition to the abrasions on the patient's body and the impact of the head, the cause of the patient's coma is unknown. Our hospital's conditions are limited. Our suggestion is to transfer the patient to Zhongjing Hospital as soon as possible. The equipment and doctors there are relatively strong strengths, so it can be determined that the patient is coma."

After Chen Zheng finished the transfer procedures, he saw Aunt Li wearing a respirator in the ambulance.

Holding Aunt Li's hand, Chen Zheng didn't say a word. In the eyes of the doctors and nurses in the car, Chen Zheng was worried about the safety of the patient. In fact, Chen Zheng was scanning the reason why Ang Lee was studying through the swallowtail.

Chen Zheng's face suddenly looked ugly, and then quickly returned to normal. From the perspective that others could not see, Chen Zheng's pocket squirmed slightly, as if a little bug was drilling into his clothes. The wriggling area came to the sleeve on Chen Zheng's hand, covering the sight of others, and an extremely thin needle appeared on the edge of the sleeve.

With a light stab, the colorless powder was pushed into the normal saline water, and flowed into Aunt Li's arm along the salt water, then along the blood vessels, into the heart, and throughout the body.

Aunt Li's toxins were not found in the hospital, so she quickly neutralized it.

When the ambulance arrived at Zhongjing Hospital, Aunt Li had already woken up, but she was still unable to speak.

After watching Aunt Li being pushed into the emergency room, Chen Zhengcai's face turned gloomy on the chair outside the emergency room.

Suddenly, before he could not notify Li Ying, Chen Zheng came to the stairwell, took out his cell phone, and unplugged Li Ying's company's phone number.

"I'll look for Li Ying!"

"Wait! Li Ying, someone is looking for it!"

Chen Zheng could hear Li Ying whisperingly ask who it is?

"I am Li Ying, who are you?"

"It's me, Aunt Li fainted just now. I'm in Zhongjing Hospital now, Aunt Li is in the emergency room."

The phone and microphone opposite suddenly fell and were quickly picked up: "I'll be back soon! You must not let my mother have something to do!"

"I know!"
