Doomsday Bunker Upgrade

　　 After eating lunch at Mo Qingyan, Chen Xin drove back to his refuge without staying.

　　 It's just that his emotions on the way are a bit agitated, and his expression is also a bit weird.

After returning to the refuge, he parked the car in the maintenance room, closed the door again, and took off his equipment. Chen Xin hurried back to the refuge and sat down on the sofa in the living room. , Calming down the excitement caused by the unexpected gain.

　　 "Help others improve their living conditions in refuges and get 100 survival points"

　　 "Helping others improve their living conditions in refuge for the first time, gaining 100 survival points"

　　 "Help 2 people to improve their living conditions and get +2 survival points every day"

　　 The system that has not had any sense of existence suddenly flashed three prompts in front of him, making it difficult for Chen Xin not to notice the information.

　　 The sudden increase of two hundred survival points, the daily survival points +2, this is undoubtedly a huge surprise for Chen Xin, and it is also a rich harvest.

　　He helped Mo Qingyan make an oxygen generator, and invested only a few points of material processing fees for survival points, but what he gained was equivalent to the survival points he obtained in half a month.

　　 With such a generous return, Chen Xin couldn't help wondering if he should make more oxygen generators for others.

　　 After all, in the three tips, except for "helping others to improve their living conditions in refuge for the first time", which is an achievement and cannot be obtained repeatedly, the other two can be obtained repeatedly.

　　 "Helping others to improve their living conditions in refuges" is a one-time income, but the system does not say that this can only be done once.

　　 Chen Xin's mind is not stupid. Oxygen concentrators can improve living conditions. Can a planting greenhouse be? What about the ventilation system? What about biogas fuel cells? What about the stronger shelter door?

　　Improving the living conditions of a refuge is the same as improving the living conditions of Chen Xin's own refuge. It is a project that can be continuously improved.

　　 This also means that he can get a lot of survival points, as long as he is willing to help others improve their living conditions.

　　Improving the living conditions of others can also gain more daily survival points, which obviously greatly increases the speed at which Chen Xin can obtain survival points.

Through these three hints, Chen Xin seemed to see that a huge number of survival points were pouring toward him, and the power armors and mechas he expected to appear after the upgrade of the refuge seemed to be slowly coming towards him. Was beckoning to him.

"To improve the living conditions of others, one person per capita means a little more every day. If I can make the official refuge also write such a line, 10,000 people will be 10,000 points per day!" Chen Xin said excitedly to himself So, although this is only his fantasy, it does not prevent him from looking forward to a bright future.

However, this is indeed very likely. As long as Chen Xin can improve the living conditions of a large refuge, according to the current prompts given by the system, a person can get a little increase in survival points every day, which is enough to get him per head. A lot of survival points.

　　 Of course, it is not easy to really want to do this.

　　 The big refuge is not like the small refuge. Chen Xin can upgrade anything casually can bring about the improvement of living conditions.

　　 For the large refuge, in order to improve the overall living conditions, it is undoubtedly necessary to upgrade the entire refuge.

　　 This obviously requires much more investment in survival points than upgrading a small refuge to achieve the goal.

　　 is like the oxygen generator of the official refuge. The biological facade of thousands of pieces is not what Chen Xin is capable of making now.

　　 Even if it is upgraded with survival points, the survival points consumed by such a large-scale equipment may be enough for Chen Xin to upgrade his sanctuary as a whole.

　　 In short, helping the Great Refuge to improve living conditions can indeed bring rich returns, but it is not something that Chen Xin can afford now.

　　 But this also gave Chen Xin another way of thinking. It does not affect the large refuge, and there are small refuges to use!

In the survival group formed by Chen Xin and Mo Qingyan, many people built their own refuges. According to statistics after the disaster, all group friends together have more than 20 private refuges.

Although in the past few months, a small group of friends abandoned their refuges due to insufficient preparation or the original plan was just to survive the disaster, and went to the official refuge with supplies, but there are still 19 private refuges. It survived.

　　 Five of them are in Linshi, two are in Sanzhen, and the remaining twelve shelters are in this city except Chen Xin and Mo Qingyan.

　　 In the previous routine communication, everyone’s situation was pretty good, there was no big problem, and the material reserves were relatively sufficient, except for the exchange of supplies, there was no need to exchange materials.

　　 But for Chen Xin now, these ten refuges are Baihuahua’s survival points!

You don’t even need more ~www.ltnovel.com~ Each shelter will send an oxygen generator, which can provide Chen Xin with a thousand points of survival. As long as he collects some more by himself, he can use the materials to upgrade the whole Sanctuary.

Thinking of this, Chen Xin couldn’t help getting excited. He had already seen the power of the system upgrade function. If he could upgrade the refuge as a whole, he would undoubtedly bring him better living conditions and make him better in this doomsday. stay alive.

　　 The current temperature has dropped to zero, and it will continue to drop. If you can’t prepare for it, the coming extreme cold will be enough to freeze anyone who is not prepared enough.

　　 As for why helping others to improve their living conditions can get survival points, Chen Xin didn't think it was any strange.

　　 Human beings are social animals that live in groups. Helping others can actually be regarded as improving the overall social environment. When the overall social environment is good, the individual's living conditions will naturally be improved.

　　 After all, in this difficult environment under the apocalypse, it is obviously easier to survive in unity and cooperation than alone.

　　 It’s like the refuges that survived the end of the ice age. If we don’t communicate with each other and help each other, how can we survive in the end?

　　 If Chen Xin doesn't have a system, I'm afraid he should be very eager to exchange materials with other people, right?

　　 After all, although everyone stores materials according to the same list, the materials that everyone can purchase are different, and the shelters built are also different.

　　 Just like him and Mo Qingyan, he has vegetables, and Mo Qingyan has wine and canned meat. The exchange between the two of them can complement each other to a certain extent.
