My Post-Apocalyptic Shelter Levels Up Infinitely!

【Powerful Raincoat】

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

Upgrade direction one: Improve the material of the raincoat, add insulation materials, improve wearing comfort, improve wind resistance, and need survival points (85)

Upgrade direction two: Improve the material of the raincoat, add optical materials, improve concealment, and slightly improve windproof and heat insulation capabilities, which requires survival points (120)

"Both directions"

"The first one is obviously to improve disaster resistance, and the second one is to evolve towards combat uniforms?"

Boom…

Boom…

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

When upgrading the raincoat before, the system gave an option to evolve in the electric direction, but this time it surprisingly canceled the electric upgrade direction and switched to the stealth direction.

Based on current needs, upgrading can be done in two directions, both of which can provide a lot of help in daily life.

But if it involves the subsequent upgrade direction, it will be difficult.

When a disaster strikes, the first factor must be to prepare for survival, otherwise everything will be empty talk.

After thinking about this, Sumo no longer hesitated and blurted out:

"I choose the upgrade direction"

"two!"

As soon as he finished speaking, 120 survival points were deducted.

This time, what emitted from the body was not the usual green light, but a red light that seemed to emit heat.

The light hit the raincoat directly, and 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 the color expression has begun to approach the color of the workbench.

“What an amazing feature”

"Just by placing it on the table, it can have a certain degree of optical invisibility."

[Optical Combat Suit (Excellent)]

Description: A combat uniform with excellent performance, it has excellent special effects of being waterproof, anti-violet and infrared, slightly windproof and heat-insulating.

Special ability: Optical invisibility (at a certain angle, negative refractive index metamaterials and transformation optical structures designed based on this material can bend light, thereby achieving "optical invisibility")

Rating: If you can keep upgrading I mean if you can maybe open the door to a new world!

Picking up the upgraded optical combat suit, Sumo looked at it carefully and found a clue.

If it is not viewed directly from the front, as long as the optical combat suit is moved to a 45-degree angle of sight and backward, there will be a certain degree of optical invisibility effect.

He had never seen this effect on Earth before, and this 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 previous raincoat was said to be close-fitting, it actually still had a certain distance, so you would feel a little inconvenient during extensive activities.

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

If you deliberately don't feel it, it will even feel like you are wearing a 01 raincoat to fight, giving you the feeling that you are almost not wearing it at all.

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

In order to get familiar with the feel of the combat uniform as soon as possible, Sumo simply took out the pottery plate armor that he was going to upgrade last and put it on the table to study.

[Hunter's Terracotta Armor]:

Description: Excellent material, neat wiring, considerable defense power, unique hidden grass smell, which can cover the hunter's body odor.

Upgrade direction one: Change the armor shape to half-length light armor, slightly improve the material, retain the body odor masking properties, improve protection, and require survival points (105)

Upgrade direction two: Change the armor shape to light lower body armor, slightly improve the material, reduce the weight of the armor, and improve the protection. Survival points are required (130)

Upgrade direction three: Change the armor shape to full-body light armor, slightly improve the material, add an electric power-assist device to improve protection, and require survival points (180)

Among the three options given, Sumo decided on upgrade direction three without thinking about it.

Electricity is the primary productive force.

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

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

Without an electric device, even if the weapon is upgraded to be as sharp as iron and the armor is upgraded to be extremely strong, it can only be a slightly more powerful hand-to-hand fighter.

In the apocalypse, if you rush forward and rely on personal force to fight hand-to-hand, the risks are great, and Somo naturally understands the risks.

Trying to invest in existing materials, after adding two units of iron blocks, the upgrade price dropped to 165 and did not change.

Gritting his teeth and restraining his inner urge to save survival points, Somo slowly chose direction three.

The pottery plate armor, which followed Soma through life and death, completed its mission.

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

The green light was like a pair of invisible hands, starting to knead the shape of the liquid out of thin air.

What was originally a pool of liquid gradually began to solidify, and the details gradually began to adjust according to Soma's body shape.

After three to five seconds, the green light dissipated.

Snapped!

The unpowered armor fell to the workbench with a muffled sound.

A set of full-body armor that not only covers the upper and lower body, but also comes with a pair of shoes and a silly-looking helmet.

"Forget the helmet, even if I am wearing this now, if someone shoots me in the head, I will die."

After touching the complicated patterns on the helmet and checking that the electric device was not on the helmet, Sumo returned it to the equipment warehouse.

The huge helmet will open up the optical combat suit, which is equivalent to blowing up the school building and committing crimes against the wind.

"The upper body armor and lower body armor are not heavy, and wearing them will not affect your activities."

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 weighing the weight of the two pieces of light armor, Somo nodded.

"It seems like the electric device is hidden in the shoe."

Picking up the light armor shoes placed on the table, Sumo looked into the light.

Two long strip-shaped devices extend from the upper part of the shoe, from front to back, and to the tail of the shoe. It is unknown where the battery is. The location of the battery cannot be seen from the appearance of the shoe.

After searching, Sumo found the charging port at the heel of the shoe and the inductive opening button at the toe.

"The inability to automatically recognize and activate the danger sensor is perhaps the biggest disadvantage of the electric device, but it doesn't matter. You only need to stare at the ground with your toes to turn it on, which is quite convenient."

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

Special crossbow arrows!

The crossbow arrows made by the game are completely sufficient to deal with ordinary kobolds, but if you enter the enemy's territory during this trip, you may inevitably encounter more powerful enemies.

In order to ensure the lethality, Sumo planned to make a batch of special crossbow arrows that were completely different from ordinary crossbow arrows.

Return to the energy room, connect the generator power, go to the table and turn on the workbench switch.

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

About ten minutes later, Somo opened his eyes and focused closely on the material in front of him.

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

With his left hand, he switched to high-speed cutting mode. Facing the iron block in front of him, Sumo evenly divided the iron block into ten 18cm long small iron blocks like a butcher unloading a cow.

The crossbow arrows produced by the game panel are in the standard size of 25cm, which combines lethality and arrow speed.

While it is uniform, it actually loses its characteristics.

This time, Somo took a different approach, starting from the length of the crossbow arrows, and began to improve the length of the broadsword and the axe.

Following the style of the system crossbow arrows, Sumo focused all his attention on cutting and polishing to ensure that the width near the arrowhead and the arrowhead were as consistent as possible.

After wearing the robotic arm, the stability of the arm allows Sumo to greatly relax the requirements for arm accuracy.

A little spark scattered out and hit the stone wall.

Soma's production is very serious and the efficiency is extremely impressive.

A crossbow arrow only takes about 3 minutes to make, and is set aside to cool.

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

This kind of work requires a high degree of concentration. If you are not careful, a crossbow arrow will be completely scrapped and need to be remade.

Fortunately, with the concentration bonus of the excellent workbench, none of the ten crossbow arrows failed!

New day, new hope! Come on, brothers! By the way, I recommend (xian) recommend (ji) a book called Young Seedlings by the Big Brother. Readers who like to read it can go in and take a look!
