My Post-Apocalyptic Shelter Levels Up Infinitely!

　　【Strong raincoat】

　　 Description: A raincoat that has been upgraded many times. It currently has three capabilities: strong rain, red and ultraviolet, and low heat insulation.

　　 Upgrade direction 1: Improve raincoat material, add heat insulation material, improve wearing comfort, improve wind resistance, and need to survive (85)

　　 Upgrade direction 2: Improve raincoat materials, add optical materials, improve concealment of wearing, and slightly improve wind and heat insulation. Survival points are needed (120)

　　 "Two directions..."

　　 "The first one is obviously to improve performance against disasters, and the second one is...evolving towards combat uniforms?"

　　咚...

　　咚...

　　 Sumo tapped the desktop with one hand, looking at the two options given by the system, and fell into deep thought.

　　 When upgrading the raincoat before, the system gave the evolution to the electric direction, but this time it unexpectedly cancelled the electric upgrade direction and turned it into a stealth direction.

　　In terms of current needs, upgrading can be done in both directions, and both can provide a lot of help in daily life.

　　 But if it involves the future direction of upgrading, it can be difficult to do.

　　 A disaster is coming, the first factor must be preparation for survival, otherwise everything is empty talk.

　　 Thinking of this, Somo stopped hesitating and blurted out directly:

　　 "I choose the upgrade direction..."

"two!"

When the voice of 　　 falls, 120 survival points will be deducted.

　　 This time, the green light scattered from the body is no longer the usual green light, but a red light that seems to emit heat.

　　 The light hit the raincoat straight, and a series of sequins that were difficult to dazzle began to appear on the raincoat.

　　 Visible to the naked eye, the original loose material of the raincoat has become more delicate, and in terms of color performance, it has begun to approach the color of the workbench.

　　 "What a magical function..."

　　 "Just put on the table, you can have a certain degree of optical invisibility"

　　【Optical combat uniform (excellent)】

　　 Description: A combat uniform with excellent performance, with excellent special effects such as waterproof, violet and infrared, and slightly windproof and heat insulation.

　　Special ability: optical invisibility (at a certain angle, the metamaterial with negative refractive index and the transformation optical structure designed based on this material can bend light to achieve "optical invisibility")

　　 Evaluation: If you can keep upgrading... I mean if... you might open the door to a new world!

　　 picked up the upgraded optical combat uniform, Suma looked carefully and found a clue.

　　 If you are not looking directly from the front, as long as you move the optical combat uniform to the 45-degree angle of the line of sight, there will be a certain degree of optical invisibility.

　　 He hadn't seen this kind of effect on earth, and it was the first time he saw it now.

　　 Trying to wear it on his body, Somo moved his arms and legs, and felt a completely different feeling from before.

Although the raincoat before 　　 is said to be close-fitting, there is still a certain distance, and you will feel a little inconvenience during large-scale activities.

　　 Now the upgraded optical combat uniform is like a film, completely sticking to the skin.

　　 If you deliberately don't feel it, you will even be able to wear a 0.01 raincoat to fight, giving birth to a feeling of hardly wearing.

　　 The mask, which was originally made of plastic, has also been upgraded to a more advanced soft rubber, which is more breathable and protective.

　　 In order to get acquainted with the feeling of the combat uniform as soon as possible, Somo didn't take it off at all, and directly took out the last ceramic plate armor to be upgraded and put it on the table for study.

　　【Hunter's pottery armor】:

　　 Description: Sophisticated material, neatly routed, considerable defense, unique hidden grass smell, which can conceal the body odor of hunters.

　　 Upgrade direction 1: Change armor shape, change to half-length light armor, slightly improve material, retain body odor masking characteristics, improve protection, and need to survive (105)

　　 Upgrade direction 2: Change armor shape, change to lower body light armor, slightly improve material, reduce armor weight, improve protection, and need to survive (130)

　　 Upgrade direction 3: Change the shape of the armor, change to light armor, slightly improve the material, add an electric power assist device, improve protection, and need to survive (180)

Among the three choices given by 　　, Somo hardly thought about it, and decided on the third upgrade direction.

　　Electricity is the primary productive force.

　　 No matter what kind of device is used to burn the boiler and convert the power in the future, the cheapest and most convenient resource will always be electricity!

　　With an electric device, in the eyes of foreigners who don’t know technology, he will also be a human using "magic".

　　 Without an electric device, even if the weapon is upgraded with iron like mud, and the armor upgraded is unusually strong, it can only be a slightly stronger melee fighter.

　　 In the last days, rushing up and relying on personal force to fight hand-to-hand, the risk is great, which is lighter and heavier, Suma naturally distinguished.

　　 tried to invest in the existing materials, after adding two units of iron, the upgrade price dropped to 165, not changing.

　　 gritted his teeth and restrained his inner urge to save a point of survival, Somo slowly chose the third direction.

　　 The ceramic plate armor that followed Somo's birth and death has completed his mission.

　　 In the next second, under the terrifying power of green light, it was melted into a puddle of gray-black liquid.

　　 The green light is like a pair of invisible big hands, beginning to knead the shape of the liquid out of thin air.

　　 was originally a puddle of liquid, and gradually began to condense, and gradually began to adjust the details according to Somo's body shape.

　　 After three to five seconds, the green light dissipated.

Snapped!

　　 The unassisted armor fell on the workbench, making a muffled noise.

　　 A set of full body armor, not only the upper body and the lower body, but also a pair of shoes and a helmet that looks stupid.

　　 "Never mind the helmet, even if I wear this thing now, if someone blows my head, I will die"

　　 After touching the complicated pattern on the helmet and checking that the electric device was not on the helmet, Somo put it back in the equipment warehouse.

　　The huge helmet will open the optical combat uniform, which is equivalent to bombing the school to build a paradise and committing crimes against the wind.

　　 "The upper body armor and the lower body armor are not heavy, and they won’t affect the activity when worn.”

　　 Light armor weighing about ten kilograms can not only provide a certain degree of protection, but also ensure that it will not affect the dodge speed during combat.

　　 After measuring the weight of the two pieces of light armor, Somo nodded.

　　 "In that case, the electric device should be hidden in the shoe..."

　　 picked up the light-armored shoes placed on the table top, Somo faced the light and looked in.

　　 The two elongated devices extend from the upper part of the shoe, from front to back, to the end of the shoe. I don’t know where the battery is. The shoe is completely invisible from the outside.

　　 looked for it, Somo found the charging port at the heel of the shoe tail, and the inductive opening button at the toe.

　　 "It can't automatically recognize the danger induction switch. Perhaps it is the biggest drawback of the electric device, but it doesn't matter. To switch on this thing, you only need to stare at the ground with your toes, which is quite convenient."

　　 After taking the shoes on the ground and connecting them to the power source with the charger, Somo began to prepare the last thing.

　　Special crossbow arrows!

The crossbow arrows made by the game are completely sufficient to deal with ordinary kobolds, but this trip into the enemy territory, it is inevitable that you may encounter more powerful enemies~www.readwn.com~ In order to ensure the lethality, Suma plans to make a batch A special crossbow arrow completely different from ordinary crossbow arrows.

　　 Go back to the energy room, plug in the generator power, come to the desk and turn on the workbench switch.

　　 took out a unit of iron and put it on the table, Somo began to close his eyes and rest.

　　 About ten minutes later, Somo opened his eyes, his attention was highly concentrated, and he looked at the material in front of him.

　　 The robotic arm in front of the workbench senses the approach of the arm, and automatically starts to attach the package, and then merges into one.

　　 Switched to the high-speed cutting mode with his left hand, facing the iron block in front of him, Somo was like a cow, and he evenly divided the iron block into ten small iron blocks of 18cm long.

　　The crossbow arrows produced by the game panel are 25cm standard specifications, which have both lethality and arrow speed.

　　 Even though it is uniform, it also loses its characteristics.

　　 This time, Somo took a different approach, starting from the length of the crossbow arrow, and starting to improve the sword and the axe.

　　 imitating the style of the system crossbow arrow, Somo focused all on cutting and polishing, ensuring that the width of the arrow and the tail of the arrow are as consistent as possible.

　　 After putting on the robotic arm, the stability of the arm allows Somo to greatly relax the requirements on the accuracy of the arm.

　　 A little bit of sparks scattered out and hit the stone wall.

　　 Somo is very serious in making it, and the efficiency is extremely impressive.

　　 A crossbow arrow can be made in about 3 minutes, set aside for cooling.

　　 After 10 pieces were made, Somo’s back was already wet with sweat.

　　 This kind of work that requires a high degree of concentration, once a little careless, a crossbow arrow will be completely scrapped and needs to be rebuilt.

　　 Fortunately, there is an excellent level of workbench concentration bonus, and ten crossbow arrows have not failed!
