"Wuwu, master, you finally came to look for me."


    The ‘wuwu'' noise was the sound of wheels moving across the concrete floor.


    After returning to the surface, Chu Guang first went to the third floor of the nursing home.


    He originally nned to find Little Seven to determine the situation, but before he even reached the window, he saw the paper bin moving towards him pitifully.


    Chu Guang looked at it dumbfounded, not knowing what happened to it."What''s the matter?"


    "Little Seven has only one bar battery left."


    ‘Oh, I thought it was something else.''


    ‘Wait……''


    Chu Guang: "Where can I find a ce for you to recharge?"


    Little Seven: "I have a wireless charging port on my body, I just need to go back to the shelter for a while!"


    Chu Guang: "..."


    ‘No wonder I haven''t found a socket in the shelter and theputer without a mainframe on the table also never runs out of battery. It turns out to be high-tech.''


    ‘Although wireless charging is not really high-tech.''


    Lifting the paper bin-shaped robot, Chu Guang walked downstairs.


    After obediently retracting its bottom wheels, Little Seven suddenly blurted out.


    "By the way, master."


    "What''s wrong?"


    "I suddenly remembered that the power system of our shelter seems to be powered by a nuclear fusion reactor core."


    "Nuclear fusion?"


    "Mhm, so the electric energy in it can be used for a long, long time."


    "Oh, that''s a good thing." Chu Guang replied absentmindedly. He was already thinking about how to steal the electricity inside.


    Little Seven continued.


    "Although, this may not be a good thing."


    Chu Guang''s thoughts were interrupted by this sentence, and he, who was walking down the stairs, stopped.


    "What do you mean?"


    "Because it is now 2340. Compared with the year when the shelter was built, it''s already been a long, long time..."


    "What?!"


    Chu Guang asked hurriedly.


    "What will happen if the electricity runs out?"


    However, Little Seven''s reply made him almost spit out a mouthful of old blood.


    "I have no idea."


    "You have no idea???"


    How could it have no answer to such an important question!


    Wasn''t there an emergency n???


    Little Seven spoke cautiously.


    "Because ording to the n... this shelter should have opened a hundred years ago, but I don''t know why it was dyed for a whole century."


    Chu Guang: "..."


    Seeing that Chu Guang didn''t speak, Little Seven continued to speakfortingly.


    "In fact, you don''t need to be too pessimistic. The power room of Shelter 404 should be on the third floor of the shelter. As long as you unlock that floor and rece the fuel rods in time, then everything will be fine."


    Chu Guang almost wanted to scream.


    "Where am I going to get nuclear fusion fuel rods!"


    They were 211 years in The Wastnd Era.


    Little Seven: "Uh, there is always a way, right?"


    Chu Guang: "..."


    In any case, he couldn''t take out his anger on electronic products.


    That would be too pathetic.


    Chu Guang put Little Seven by the elevator and watched the paper bin robot roll back slowly.


    Chu Guang felt a little irritable, but he also knew that it was useless to be anxious at this time, and the problems had to be solved one by one.


    In the short term, there should not be a big problem with electricity. Even if the opening of the shelter was dyed for a century, it had not been running in the past century. It should have been operating in an energy-saving mode. Maybe the remaining electricity could be used for decades.


    In contrast, he should be more worried about theing winter.


    There was not much time left for him to prepare...


    Leaving the nursing home, Chu Guang arrived in front of the cement kiln and found that the yers were energetically busy and had already started the second cement kiln.


    There were also eight smaller ones for making charcoal neatly erected next to them.


    It seemed like they were going to skip the agricultural age and leap directly into industrialization!


    Chu Guang was overjoyed.


    It was all thanks to his wit and management!


    Seeing the administratoring, Old White wiped the dust off his face, excited like a kid. He stood up and said.


    "Administrator!"


    "Mhm, I went down to the basement earlier... Are these your ideas?" Chu Guang asked when he looked at the earthen cement kilns behind him.


    "It''s everyone''s hard work!"


    "You don''t have to be modest, I can see it, the organization will remember your contributions!"


    Old White looked excited.


    Wasn''t this what he was waiting for!


    Especially the second half sentence.


    "...In addition, on behalf of the organization, I will give each of you 1,000 contribution points as amendation for unlocking cement and building materials. And from now on, you will be the construction leader of the shelter outpost!"


    "You are free to use your creativity to design and build our outpost within the scope of nning."


    It would''ve been great if there was a "ding~" sound effect at this time.


    That must be cool.


    Or at least, a pop-up window that could show reward prompts in the eyes of yers.


    Unfortunately, there was nothing like that.


    But even so, even these kinds of verbal promises andpliments made Old White excited.


    Achievement!


    ss!


    And, favorability!


    It seemed that the hidden system of this game was richer than he had imagined!


    "Dear administrator! I will do my best to build our home as much as I can!"


    The other three yers all looked at him with envy.


    Although everyone had obtained contribution points, it was obvious that Old White, who got the position of "leader of construction", received the most benefit.


    Having the permission to freely construct facilities? What kind of construction team leader was this? It was clearly the director of the nning office of Wastnd Online!


    The awesomeness of this ss was off the chart, alright!


    Looking at the excited Old White, Chu Guang nodded approvingly and said.


    "Very well, now I need you to tell me your n."


    "Yes!"


    Old White stood with his back straight and began to report.


    ording to Old White, after going offline yesterday, he conducted a field survey of the actual cement factory and asked the workers in the factory. He learned that adding iron powder to the cement could get stronger and more durable cement.


    Talking about content outside the game in-game seemed to be automatically ignored by the NPC. Seeing that the administrator did not respond, Old White went directly to the topic.


    Considering that there was rusty steel everywhere on the wastnd, he mixed the collected iron rust with charcoal, used thetter as a reducing agent to make iron by calcination, and then calcinating the smelted iron g together with wooden ash cement.


    Although this seemed to increase the production cost of cement, the cement produced in this way could be used to make cement kilns that were more durable, resistant to high temperatures, and had greater output.


    "It is impossible to producerge quantities of cement by relying on these earth kilns, so I n to put all the cement produced in the early stage into the construction of production facilities to further increase the output of cement!"


    Chu Guang nodded approvingly.


    "That''s a good idea, but... how much cement can be produced by just using bark?"


    Just now, Chu Guang noticed that not only had the pile of logs they cut down been stripped of its bark, but so had the trees near the nursing home been almost stripped naked by these survivors.


    They didn''t even let the stumps go!


    Old White had obviously considered this question and replied confidently.


    "Because of this, we need a more professional cement kiln... the kind that can produce a high temperature of 1450 degrees! This way, we can make calcium carbonate cement by burning limestone and y,pletely recing the raw material of wooden ash!"


    Wooden ash cement containing potassium and sodium was not the most ideal building material, but it was a good substitute when conditions did not permit it.


    After being appointed as the construction team leader, Old White suddenly had greater ambitions.


    What he saw was no longer just a wall, or a certain building of the nursing home.


    It was the whole wastnd.


    He wanted to transform this world into what he had in mind!


    "You have aprehensive consideration, so you can follow your n."


    Chu Guang nodded, then looked at the other three yers.


    "In the next few days, two neers will end their dormancy and join our advanced team. I n to host a small banquet to wee them, so I need to get some game back... I can''t treat them to porridge."


    After a pause, Chu Guang continued.


    "Who wants to go hunting with me?"


    As soon as his voice fell, two people raised their hands in a swish.


    Chu Guang was stunned.


    Goodness, even the construction leader he just appointed raised his hand!


    "Ahem, we don''t need so many people... Night Ten, you are a Perception-type, so youe with me."


    "Yes! Administrator!"


    Night Ten bowed with excitement, and under the envious eyes of the three yers, swaggered to stand next to the administrator.


    Chu Guang looked at the other three yers and said seriously.


    "Your mission is also very important. Cement is the top priority for the development of the outpost. We have enough wood for the time being, so the logging work can be stopped for a while. I need you to fully produce cement. Can it be done?"


    Although it was a pity that they could not go hunting with Administrator, the three yers still obediently followed his arrangement.


    "Yes, we willplete the mission!"


    ‘Very good.''


    ‘As expected of my appointed yers!''


    Chu Guang nodded in satisfaction, and walked towards the woods south of the nursing home with the Night Ten who was grinning from ear to ear
