My Post-Apocalyptic Shelter Levels Up Infinitely!

　　 killed two magical creatures that seemed to have come out of the fantasy world. On the way to the refuge, the mutant creatures that scared Suma in the past seemed much cute.

　　 "It's ridiculous to rub the fireball... if all the creatures described in the fantasy novels are to appear one by one, the survival of human beings will be in jeopardy."

　　 The power of the fireball is not great.

　　 This kind of monster, as long as a human holds a Gatling gun and has a bunker, even if it comes up to dozens or hundreds at a time, it is difficult to break through the metal defense line.

　　 But other than that, if there are other creatures like dragons in myth...

　　 "I hope not, otherwise humans will only become mice in the hole forever!"

　　The more he thought about the future of mankind, Somo felt that the future was slim.

　　 shook his head, forcibly forgetting all the worries in his mind, and seeing the shelter that had appeared at the end of the horizon ahead, a long-lost sense of security came.

　　Golden nest and silver nest, where can I have my own doghouse!

　　 In just six days, Somo has completely regarded this land boundary as his own territory.

　　 Oreo, with his tail drooping along the way, became more energetic as he got closer and closer to the refuge.

　　 After carefully looking at the sight of no strangers near the refuge, he came to the back of the hill, Somo opened the back door of the refuge and got in.

　　 squatted through the long tunnel, and as his eyes suddenly became clear, he returned to the shelter again, one person and one dog.

　　 The quiet light of daylight refracts the vents and spills down.

　　 formed a dazzling beam of light.

　　 In the beam of light, a little dust can be seen dancing in the air with the naked eye.

　　The vegetable culture medium placed in the center of the base, although there are still no green sprouts, the fragrance of earth that comes out brings a breath of life to the base.

　　 "This is my refuge, if you want to destroy it, step on my body first"

　　 At the thought of the refuge nowadays, these kobolds and beasts would break into the door and be completely destroyed, and Su Mo's fists hardened.

　　 sat at the table, taking advantage of the sunlight, Somo took out the crossbow from the space and placed it on the table.

　　 After a few days, I have enough survival points and generators, and it is imminent to upgrade the electric automatic weapons.

　　 A crossbow bow that can only shoot one shot of a crossbow arrow is still useful when hunting, but if it faces the enemy head-on, there are too many restrictions.

　　 Especially when encountering such a monster with magical power, it is not enough to look at it.

　　 Concentrate, meditate on the system in his heart, and Suma looks at the crossbow.

　　【Hunting compound crossbow (normal)】

　　 Description: Long-range combat tool, slow reloading speed, high initial velocity, and considerable lethality. It is an indispensable tool for wilderness survival.

　　 Rate of fire: 140m/s

　　 Range: 80m (maximum kill) 165m (effective kill) 330m (farthest kill)

　　 Upgrade direction 1: Upgrade crossbow materials, increase crossbow pounds, reduce winding pressure, and need to survive (180)

　　Upgrade direction 2: Upgrade crossbow materials, add electric winding device, change design mode, increase automatic firing burst mode, increase projectile capacity (400)

　　 "The second upgrade direction requires 400 survival points. After upgrading the generator, I now only have a balance of 303 points. Let's see if I can find a way to get some items in to reduce demand."

　　 After pondering, Sumo's thoughts concentrated, and the upgrade demand for direction one jumped out.

　　 Throwing away some parts that have never heard of the name, Somo noticed two major items in the demand:

　　500W electric motor, composite lithium battery or lead-acid battery.

　　 "Good guys, this 500W motor can weigh five or six kilograms, but adding a big battery, let alone the weight of the crossbow has gone 20 kilograms."

　　 "Also, considering that metal fatigue is severely intensified, if the rate of fire is increased, it will not be damaged after a long time.

　　 After a little calculation in his mind, Somo discovered the advantages and disadvantages of the electric crossbow.

　　 The lethality brought by the 500w motor is definitely enough, even if the mid-way loss is counted, it can have at least 200 joules of kinetic energy.

　　 But at the same time, such a manic output power is bound to bring about precision defects. The battery and motor must be placed in the rear, so that the center of gravity of the entire weapon is all back. It is estimated that it will be difficult to aim properly.

　　 "Forget it, there is no good solution to worry about so much, so I will solve the current problem first."

　　 Keeping all the approximate parameters in mind, Suma opened the trading market and began to search for products.

　　 After adding the handling fee, the current trading market is no longer as hot as the previous few days, and hundreds of thousands of pages of goods have become seven or eight pages a day.

　　 Few people are wealthy enough to be like Somo now, and they use their points to pay for express delivery to purchase items.

　　 After turning all the pages and finding no items, Somo had no choice but to come to the World Channel.

　　 [Somo: Acquire a 500W electric motor with unlimited size and weight, as well as composite lithium battery or lead-acid battery]

　　 [Suma: I opened my request and I was responsible for the express delivery costs. I have some items to sell, so I quickly bought them and traded them! 】

　　 After the first disaster, everyone’s daily conversation speakers became two.

　　 When Somo's first speech appeared on the World Channel, it hadn't caught everyone's attention, but when the second one followed, it immediately detonated the World Channel.

　　 "Fuck, the front row hugged me Su Shen, the fairy touched my head, my hair was tied for longevity, not much to say, this wave of luck I gathered to open the box"

　　 "Congratulations, you got the claw knife-the quality was lost, sorry, I went to the wrong set"

　　 "Motor, lithium battery...Is Su Shen already in the electrical age? I still light a torch? Oh, I don't even have a torch, that's all right!"

　　 "I have a lithium battery installed on a mobile phone, would you like Su Shen?"

　　 "This express fee is not cheap, right... It's really inhumane"

　　 "Our Huaxia is really amazing! Foreign Somos are not good, our Huaxia Sumos are good!"

　　 With the passage of time, more and more people flocked to the World Channel, just to pay tribute to Somo's speech in the front row.

　　 Seeing the heat rise, Somo was also happy, and directly posted the acquisition information on the trading channel.

　　 After a while, after spending 800ml of You Energy Water and 11 points of disaster points, I successfully received a simple and simple model, as if the motor was disassembled from an electric car, weighing a full 12kg.

　　 As for lithium batteries, after some screening, Somo bought two sets of batteries for the price of 600ml of Nether Energy Water and 40 points of disaster points. They are:

　　 20Ah, 12.8v ternary lithium battery, used to install on the electric crossbow. UU reading www.uukānshu.com

　　 400Ah, 12.8v standard lithium iron phosphate battery, used as the daily electricity consumption in the early stage of the shelter.

　　As a 12-volt standard battery, a 400Ah battery can store about five kilowatts of electricity at ordinary times, which is sufficient for the initial use of the shelter.

　　 After sending out the crossbow, battery and motor, this time, when Somo was watching, the survival point requirement changed.

　　【Hunting compound crossbow (normal)】

　　 Upgrade direction 1: Upgrade crossbow materials, increase crossbow pounds, reduce winding pressure, and need to survive (180)

　　Upgrade direction 2: Upgrade crossbow materials, add electric winding device, change design mode, increase automatic firing burst mode, increase projectile capacity (220)

　　 "Huh? The two most important items have only been reduced by 180 points... Can this upgrade also change the material properties?"

　　 Without hesitation, Somo directly chose to upgrade.

　　 With a flash of light, after 220 survival points were deducted, a green light scattered out, almost fusing the three objects into a pool of blue water in less than a second.

　　 As the frequency of the green light scatters more frequently, the water-like objects begin to condense and gradually become new ones (please see this chapter).

　　 The motor that weighs a full 10 kilograms has disappeared, and the bulky lithium battery has no idea what it has become.

　　 A device similar to an airbag is formed under the original hand rest.

　　 The most important thing is that the newly released electric crossbow comes with a luxurious sight, which is really exciting.

　　 Looking at the big killer in front of him, Sumo, who was worried that the kobolds might attack, suddenly appeared a green number on his head!

　　 A sense of security +10000!
