Doomsday Bunker Upgrade

　　 Chen Xin was extremely excited about the discovery of the system.

　　 It feels like a child bear suddenly got a novel toy. You can't stop without having a good time.

And now hiding in the refuge, all the electronic products are wrapped in tin foil and placed in an iron box to avoid the next EMP shock wave. In addition to tossing about his newly acquired system, he does indeed There is nothing else you can do.

　　 But Chen Xin's tossing caused him to figure out how the system he had picked up worked, and what capabilities it had.

　　 The system itself is very rudimentary. It is not so much a complete system as it is an auxiliary program.

　　 There is no interface for the entire program. What is displayed when Chen Xin swaps out the system is only the survival point balance in the corner of his retina, and the relevant upgrade information of the items that can be touched in Chen Xin's realization.

　　 For example, when Chen Xin kept his gaze on a ballpoint pen he placed on the table, he could see two different upgrade schemes appearing on the ballpoint pen.

　　 One is to add a bright flashlight function to upgrade the ballpoint pen to a pen-shaped flashlight commonly used by doctors in hospitals; the other is to add a broken window function to make it a survival tool.

　　 The first type, Chen Xin, is often seen in various medical dramas. The pen that can turn into a bright flashlight with one click is really convenient. Doctors can use it to check the patient's body anytime and anywhere. It is a very practical tool.

　　 As for the second type, in fact, as a wild survival enthusiast, Chen Xin has such a pen in his hand.

Made of all titanium alloy, the texture is hard and can be used as a tent nail or even a crowbar. It adopts a bolt-type structure, which is much more reliable and easier to use than a button pen. The pen tip is designed to be The broken window cone can be used to smash the car window to escape when encountering things such as car accidents. It is a very practical and convenient pen.

　　 Chen Xin also likes it very much. He used to bring it with him. When he has inspiration, he can take it out and record his inspiration.

　　 is just a titanium alloy pen, of course not cheap. Chen Xin bought this pen for more than 400 yuan.

　　 If it weren't for Chen Xin as an online writer, the manuscript fee income is still OK, he might not be so lavish to buy such an expensive pen.

　　 But now, it doesn't need to spend more than 400, only a two-dollar ballpoint pen, plus 5 survival points, Chen Xin will get the same titanium alloy tactical pen.

Of course, although Chen Xin has a try to see what is going on with the system upgrade, but because there is no survival point at hand, he can only look at the upgrade plans of various items given by the system. Solve the greedy.

The system’s survival point settlement method is based on midnight every day for settlement, and Chen Xin must be settled in a 24-hour cycle, which means that Chen Xin must stay in the doomsday environment for 24 hours. , Can get the survival point of one day.

　　 But as a novice benefit and as the first start-up fund, although Chen Xin did not survive 24 hours today, he can still get a day's survival points.

It’s just that this kind of benefit is only available when the system is activated. If Chen Xin escapes from the doomsday crisis environment determined by the system, the system functions will be temporarily frozen. He will not activate the system again until he returns to the doomsday environment determined by the system again, but again The activated system must wait for Chen Xin to survive for 24 hours before starting to settle survival points.

　　 As for how Chen Xin left the world where the world is trapped in apocalyptic natural disasters, this cannot be answered by this system that does not speak artificial intelligence.

Because there is no survival point, Chen Xin didn’t bother to consider how many points it would cost to upgrade the items. Instead, he went through all the things in his refuge, and wanted to see what the system can upgrade. What are the upgrade plans.

　　 Chen Xin needs to make a plan for his future survival plan based on these upgrade plans, and at least draw up a limited list of upgrades to let himself know what to upgrade first.

Everything that appears in Chen Xin's sight can be upgraded with survival points in the system judgment. Ordinary pens can be upgraded to tactical pens, ordinary scissors can be upgraded to emergency folding scissors, and strong light flashlights can be upgraded to infrared and lasers. Functional tactical flashlight...

　　 Even the self-heating food stocked by Chen Xin can be upgraded, or can it be upgraded to a life-saving food with a bit of science fiction.

　　 However, during this tossing, Chen Xin also discovered that the system really can't make matter out of thin air, but it can transform existing matter into another matter.

　　 is like that plastic ballpoint pen that can be upgraded to a titanium alloy tactical pen. It changes the material of the pen from plastic to titanium alloy.

　　 And all of this is realized on the premise of consuming survival points, and having survival points can have everything.

　　 Of course, system upgrades are not only simply consuming survival points, but also through material upgrades. This can reduce the consumption of some survival points, but the material consumption will be larger.

　　 For example, if Chen Xin's ballpoint pen has 50g of titanium alloy, it only needs 1 survival point to complete the upgrade. If it is 200g iron, 3 survival points are required.

As for other things, they are basically based on similar upgrade rules. If Chen Xin can provide enough materials and materials, the survival points consumed by upgrading items will be much less. As for the few things, it depends on the materials that Chen Xin can provide. set.

　　 Chen Xin is very satisfied with this function of the system, which provides him with two options for survival.

　　 One kind of nature is to be the sword **** of Ten Miles. Gou keeps accumulating survival points in the refuge, and upgrades the items when he accumulates enough, until the refuge is made solid and indestructible.

　　 The other way is naturally to wait for the external environment to stabilize, and actively go out to collect materials, use materials to upgrade the shelter, and ultimately make the shelter indestructible and indestructible.

　　 The two upgrade methods are not good or bad, but they represent two different development routes, and no one stipulates that Chen Xin must choose one of them and give up the other.

　　 He can stay in the house for a period of time to upgrade the refuge to a certain level. After he has enough protection for his survival, he can go to the outside to collect materials and accelerate the upgrade of the refuge.

　　 On the one hand, it takes a certain amount of time for the external environment to stabilize, and on the other hand, because the external environment will become full of danger and uncertainty with the arrival of the doomsday natural disasters.

　　 After all, with the occurrence of a meteorite impact, most countries in the world will not be able to maintain their original order, and the original social order and peaceful environment will disappear.
