System into the end of the world

Chapter 168

There is no place for a honeymoon to get married these days, and there is no place where Star City is as safe as other places.But even so, Zhan Xuyang still took three days off for his wedding leave, and took a good time at home.

The holiday is over, and everyone is back in the intense work again.Cheng Xiangdi successfully took over the military factory, and Yu Nan can finally let go of military equipment production.

As the weather warms up, the zombie creatures in the ocean are alive again. Country N has developed an ointment that can isolate the "smell of living people". After it is evenly applied to the whole body, as long as it does not breathe heavily, it can almost make the zombie's nose malfunction.However, it is not very popular in practical applications because of the inconvenience of use and certain requirements for the thickness of the ointment.

Yu Nan began to let people cultivate a large number of purification trees, and gave them to the outside world for free when they were about 20 years old.Anyone who needs it can come to Star City to get it by themselves. The upper limit is 10 plants each time, which is enough to purify more than 4000 square kilometers, no matter how big the base is, it is enough.

At the same time, people planted this kind of tree in the flat area around Xinghai, and established the first planting base west of the aviation base along the mountain.The base is surrounded by a wall, which consists of greenhouses of different sizes.Before planting, Yu Nan asked people to dig the soil deeply, and carried out a fairly thorough disinfection, sterilization, and insecticide activities. There should be no serious pests in the future, but creatures such as prairie rats that can dig holes Still hard to put an end to.

She put a few mutated cats and dogs in it, and asked the workers in the plantation to help them raise them, but she didn't know what the effect would be.

"Master, the replacement for the recovery fluid has been prepared successfully and passed the inspection. Do you want to take a look?" It was lunch break time, Yu Nan just woke up from a nap at home, and Xiao Mu suddenly appeared and said.

"Of course." She had been waiting for this moment for a long time.I went to the bathroom, washed my face, changed my clothes and went out.

"In room 24." Entering the small factory, Xiaomu prompted beside her.

As soon as Yu Nan entered the door, he saw Mu Dong waiting here.There is a recovery instrument in the room, and several cages next to it are filled with small rabbits, white mice, kittens, puppies, etc.They all seemed to be alive and kicking, and there was nothing wrong with them, but they should all be minor patients who had been injured before. "How is it?" Yu Nan asked.

"It was very successful. After the injured animals were treated, the recovery instrument detected everything was normal. The only thing that is not as good as the original recovery solution is that the treatment time is much longer. For example, the treatment can be completed in a few minutes for a normal injury, but it may take several hours to use the replacement solution. Injuries such as amputation and life-threatening injuries may take a few days." Mu Dong replied.

"Well, it's nothing more than a waste of energy, which doesn't matter." Yu Nan nodded.She has already tried it, and any facility that uses energy crystals as a driving force can be replaced with supernatural powers, so she was overjoyed to hear that the recovery fluid that costs 1 energy per box can be replaced by consuming more energy.

"So..." Yu Nan thought for a while and said, "If you remove the one in the tree house, how many recovery instruments do we have?"

"10 units." Mu Dong said.

"Hmm...do you still have the recovery fluid? Give me some samples." Yu Nan turned her head and asked her.

"Yes." Mu Dong filled a cup with a little replacement recovery fluid from another room and handed it to her.

Yu Nan touched it with her finger, it felt a little sticky, but not sticky.She put down the cup, turned on the system, found the update prompt and pressed [OK]. "I'll get you ten boxes to replace the recovery fluid later," she paused, "I'll call it 'recovery fluid' from now on, and the previous one can be called special recovery fluid. Then send it to Star City Hospital together with ten instruments go inside."

"Ok."

Yu Nan glanced down at the progress bar that was about to be completed, and continued: "The existing treatment application procedure remains the same, but the treatment location has been transferred from the central area to the hospital. Robots are still used for the operation, and other unauthorized personnel Entry is prohibited, and those who violate the order will be demerited once." Three times will result in expulsion from Star City.

"Okay." Mu Dong replied.

"Xiaomu, help me build a high-level robot in the next two days. I need to release Mu Dong and go back to the office to help me with my work. Huh..." Before he finished speaking, Yu Nan was stunned by the system that had just been updated He stopped, and even Xiaomu didn't hear the answer from the side.After the update is complete, a new option appears in the Currency Mall called [Conversion Item].

At present, there is only one item in the conversion item, which is the "greenhouse controller" that should have appeared in the energy value mall.And the item in the energy value mall disappeared miraculously.

What causes it?
Yu Nan frowned and thought hard.She waved her hand to tell Xiao Mu and Mu Dong to be silent, she went to the chair next to her and sat down to think quietly.

To talk about the recent things related to the greenhouse controller, she helped build many greenhouses at the planting base. "Xiaomu, is there any problem at the greenhouse recently?" she asked.

"No, everything is normal and many vegetables have begun to sprout." Xiao Mu shook his head.

"Just... nothing special?" Yu Nan asked unwillingly.

"Absolutely not. Under my monitoring, I can know even if 01ml of water is added. I promise there is no problem at all."

"What's the problem?" Yu Nan frowned.

"Do you need me to analyze it for you?" Xiao Mu floated up to her, and looked up at her with effort.

Yu Nan glanced at him, a little hesitant.When she took things out of the system, she never shy away from these robots, so they clearly knew that she had something special that ordinary people didn't have.They are tacit to each other, and when they get along and talk together, the robots also carefully avoid related topics.So now, should she accept Xiaomu's help?
"Xiaomu, do you know anything about the mall?" After a moment of hesitation, she still chose to ask someone for help.The robot's setting program does not allow it to do things against the master, so there is no need to worry about safety issues.One person counts short, two counts long, let her think about it alone, and she doesn't know when she will be able to figure it out.

"What mall? An online mall?" Xiaomu blinked and asked.

"..." Yu Nan pursed her lips, with a hint of helplessness on her face. "Let me tell you this: I have two malls, one selling existing technology, and the other selling surreal technology. One day, I suddenly discovered that the 'greenhouse controller' in surreal technology actually ran into existing technology. Why do you think this is?" She turned her head to look at Mu Dong, "You should also help me think about it."

"Maybe it's because the controllers we use now are all produced by ourselves." Komaki guessed.

Yu Nan shook her head slowly, "We also produced ten recovery instruments, didn't we? But it didn't change positions."

"Is it because these controllers have been put into use?" Mu Dong also suggested a possibility.

"Well, it can be counted as a possibility. Is there anything else?" Yu Nan nodded secretly, and it was faster than she thought.

"No, this guess is wrong." Xiao Mu jumped onto the recovery device, making his own image look like he was sitting on it, with his legs still dangling. "Master, did you make those working robots yourself?"

"No." As soon as Yu Nan finished speaking, he also understood what Xiao Mu meant.

"The working robots are also made by myself and have been put into use, but their positions have not changed. It can be seen that what Mu Dong said is not true." Xiao Maki paused, "If these two points are excluded, through my calculations , I found a possibility with the highest probability."

"Tell me." Yu Nan raised an eyebrow.

"Quantity." Xiaomu replied affirmatively, "'quantitative change leads to qualitative change', because we have produced enough greenhouse controllers, so 'it'..." He bit the word "it" with extra emphasis, "So 'it' is determined that we have the ability to produce our own greenhouse controllers, so this technology becomes one of the existing technologies."

Yu Nan suddenly realized, "So that's the case." She kept nodding, and the more she thought about it, the more certain she became, "How many greenhouse controllers have we independently produced so far?" She turned her head and asked Mu Dong.Mu Dong has been following up on this matter from the beginning, so he knows best.

"103 units."

"How about before 11 am?" Yu Nan asked.

"98 units."

"Understood." When I brushed the energy crystal in the morning, I didn't find any update prompt, that is to say, the change should be between 98 and 103 units.Usually, it is an integer, that is, if you independently produce 100 finished products, you can transfer the items in the energy value mall to the currency mall.

Coming to such a conclusion, Yu Nan was so excited that he almost jumped up.She clenched her fists excitedly, stood up and walked back and forth in the room. "Let me think about it, think about it..." she muttered to herself. "Produce 100 bottles of MA5 stock solution first... No, no, no, wait a minute," she stopped, and said to Xiaomu: "You should produce the high-end robot for me first, and I will give you the formula of MA5 stock solution later. , you reproduce."

"Yes." Xiaomu bent slightly.

"Huh..." Yu Nan let out a long breath, as if he felt a lot more relaxed, "Follow what I said first. I need time to think about it and see if there is a shortcut." Look It's almost time, she waved her hand and went to work first.

"Little Nannan."

You can tell who it is just by hearing the voice.Yu Nan stopped and followed the reputation, "Why are you going?"

Zheng Jianling trotted to her side and walked side by side with her, "I was planning to pick some dates to eat." The greenhouse for growing dates is just south of the municipal building.

"Well. Didn't go to work today?" Yu Nan asked casually.Zheng Jianling now works in a supermarket and works in three shifts, and the shift schedule is different from that of the municipal department.

"Just got off work, huh?" Zheng Jianling pulled Yu Nan, and pointed to the two people who seemed to be close to each other diagonally in front of her, "Isn't that the girl who has been thinking about your Zhan Xuyang all night?"

Yu Nan stroked her forehead, feeling helpless at her choice of words. "That person's name is Zhong Qi, but it seems that since I married Xu Yang, I have changed my target." Yu Nan said.When she was bored, Xiaomu told her as gossip, and it was said that she was seduced by drunkenness or something.

"This kind of person is simply embarrassing to women. Oh, it's wrong, it should be shameless. Xiao Nannan, please quickly add a clause in the rules that prohibits selling meat." Zheng Jianling's face was full of contempt.

Yu Nan couldn't help laughing, "Their kind is not considered selling meat, and it doesn't involve money transactions. As long as the man doesn't pursue it, it's your love."

Zheng Jianling gave a "bah" in their direction and looked away.

"I'm here, let's go to work first. Be careful not to get stabbed when you pick dates." Yu Nan stopped.

"Understood." Zheng Jianling waved her hand, and the two parted ways.
