Doomsday I Have a Super Survival System

　　 The efficiency of sawing wood with a hand saw is much faster than cutting with an axe. Ankai used wood to cut trees before, of course, the trees on both sides of the city streets.

　　 On average, to chop down a tree with a thick bowl, he needs at least 20 swings of his axe. Now, to saw a tree as thick as a footbath, it only takes a minute to hold a hand saw.

　　 Regardless of the time and physical consumption, I don’t know how much it has been reduced.

　　And more importantly, the profit of using a hand saw is much higher than that of an axe.

　　 cut down a tree, he could get fifty pieces of wood, but using a hand saw to cut down a tree, he harvested 223 pieces of wood, four times the previous amount. Of course, the tree he sawed down was much thicker than the one he had cut down before, but in fact, depending on the size of the tree, the amount of wood provided is not very different. If you use an axe Even if it is a relatively large tree, after being cut down, it can provide at most about 150 wood, which is still 100 less than using a hand saw.

　　 This is the gap.

　　 It saves time and effort, and the output is higher. It is no wonder that tools such as hand saws are manufactured by the most advanced engineers. Compared with the previous tools, they are completely crushed.

　　 There are two tools of the same level as the hand saw, namely the spiral cone and the nail gun.

　　 They corresponded to the manuscript and the hammer respectively.

　　 Axe, pickaxe, and hammer are also the most commonly used tools.

　　 As for other less commonly used tools, some of them will be integrated with the machine tool in the later stage, and they are hardly used in daily life. There is also a part that has no evolutionary version, and only one type can be used from beginning to end, such as a wrench.

　　 In short, although it is not currently possible to manufacture hand saws, because it can be searched, there is no shortage of tools.

　　 For example, Ankai currently has several nail guns.

　　 The efficiency of the nail gun is not as exaggerated as a hand saw.

　　The role of the nail gun is to reinforce and manufacture. If the nail gun is used in manufacturing, it can slightly reduce the amount of material, which is of little significance. The main effect of the nail gun is to be strong.

　　 Reinforce before, and every time you reinforce, you need to hit it with a hammer several times. When there is no nail gun, the hammer is of course very useful, and there is system help. Ankai does not really rely on its own strength to reinforce or make from scratch, so generally speaking, use a hammer to reinforce, every time Reinforcement requires at least five beatings.

　　 With the improvement of the reinforcement level, this number is also increasing.

　　 I said before that, through system manufacturing, almost no physical effort is consumed.

　　 But this is almost non-consumable, not completely non-consumable, more or less consumption is still there.

And if you beat it five times, it will take a lot to tell the truth. After all, once you have to reinforce, it is not one piece or two pieces, but a large area to reinforce. Each reinforcement only has a range of almost one meter square, similar to the shelter of a pharmaceutical factory. Therefore, it takes about three to five days for Ankai to fully reinforce it once.

　　 But it's different with a nail gun. Use the nail gun to press lightly on the place to be reinforced to complete the reinforcement.

　　 is so fast, and there is no doubt that the physical consumption of this method is really almost nothing.

　　 He can easily reinforce the entire shelter in one day. In addition to the huge consumption of materials, the most consuming is the battery. In fact, most nail guns in reality use air pumps.

　　 is mainly convenient.

　　The gas pump converts electricity into high-pressure gas. The high-pressure gas brings a powerful force to drive the nail directly into the wall or wooden board.

　　 So the biggest difference is the difference in power.

　　 There are electric nail guns, but the failure rate is also quite high. The air nail gun has a simple structure and light weight, which makes it easier to use.

　　 In fact, aircraft carrier ejection still uses steam ejection. Electromagnetic ejection is a bit too complicated.

　　 In addition, in real life, many other tools can be powered by an air pump. Simply change the electric nail gun, and the air pump still needs to be used, so there is no need to use electric nails.

But also for some work that does not require much reasoning, you can use electric nail guns, such as plaster line installers, cabinet installers, or soft package installers. These people will choose electric nail guns because the air pump is really heavy. .

　　In the system, the electric nail gun is used, because at this level, there is no need for any force to assist. What power does the chainsaw need? Except for a little effort when carrying it, there is almost no effort in the whole process. Nail guns are also more of a symbolic existence. Anyway, just nailing a place is strengthened. Is there a difference between air guns and nail guns?

No.

　　 far away...

　　 Let's talk about Ankai's side.

With a hand saw, work efficiency has been greatly improved. In just half a morning, he saw down several big trees, because the thickness of the trees is different, the wood obtained is different, but even so, he also got With more than 1,000 pieces of wood, the harvest is not a big one.

　　 If he knocks wood in the city with an axe, it may take two to three days for him to harvest so much. Therefore, if he targets a certain resource alone, he finds a suitable place and the collection speed is still very fast.

Of course, don’t think that 1,000 pieces of wood are very terrible. In fact, this is An Kai’s shelter in the city. If he wants to build a shelter in the wild, this 1,000 pieces of wood will probably be able to build a few small wooden houses. If you want to make something large, it's not enough.

The construction items in the system are never limited to doors and windows, walls, foundations, floors, ceilings, roofs, fences, handrails... There are too many, if you really want to do your own DIY, the system can provide a variety of constructions project.

　　An Kai has always wanted to DIY a shelter by herself.

　　 There are advantages in the city, but there are also disadvantages. In the wild, it is actually not much worse than in the city.

　　The system is his hole card. Only with the system can he have such confidence.

　　 But it is a pity that he needs a lot of time and tools, especially tools like hand saws and nail guns, to make the system construction bar fully functional.

　　 Nail guns are actually okay. Although there are not many hardware tools shops, they can still be found occasionally.

　　 Hand saws are too difficult to find. There are no logging yards around this city, and the demand for hand saws in the whole city is very small.

　　 As for the spiral cone, it is even more difficult to find. In the city, it is generally only found on municipal engineering and construction sites. However, this thing is too big, and the places Ankai can think of, others can naturally think of.

　　 So the best way is to make it~www.wuxiahere.com~ But it is a pity that not only can he not make it, but he can’t even repair it, so this is very troublesome.

Relying on his own words, collecting materials is a big problem. Now there is Mary, but Mary can’t enjoy too much convenience. Even if she is equipped with other tools, she can’t be honest with her physical strength. What a role. "Almost" does not consume physical energy, which only An Kai can enjoy. Mary equipped with tools can only enjoy the convenience that is different from ordinary tools, but physical energy consumption is completely normal.

　　 In short, if you want to build a shelter yourself, you must at least be a Level 5 Engineer, and only after you can make and repair advanced tools.

　　 So, after all, there is a long way to go.

　　 An Kai took a short break, holding the hand saw all the time, and it would be sleepy after a long time.

　　 However, when he was resting, there was a sudden low roar behind him. The roar seemed to be suppressed deep in his throat. Although it came out, it did not spread.

　　 An Kai's face changed slightly, and she immediately stood up.

　　 And Mary, already holding a dagger in her hand, rushed past him.

　　 An Kai switched out the weapon at the fastest speed, turned around abruptly, but saw that Mary had rushed in front of a gray bear.

　　 This bear looks like a small tank, standing up, I am afraid it can be three meters high.

　　 Of course this is not the most important thing, the most important thing is the state of the bear at this time.

I saw its mouth wide open, dirty saliva left from the corners of the mouth, one eye was blind, the other eye was sickly pale, there were sores and decayed wounds all over the body, and the bear had a big face. The lump is as rotten as if it was broken by someone with sulfuric acid...

　　 The alien beast infected with the zombie virus!
