[Strong Raincoat]

Description: A raincoat with several upgrades. Has strong rain-proof ability, UV ray resistance and three layers of heat insulation.

First upgrade option: Improve the raincoat's material. Additional heat insulation material that increases comfortability and wind-proof ability. Survival points required (85).

Second upgrade option: Improve the raincoat's material. Additional photometric material that increases invisibility and slightly increases wind-proof and heat insulation ability. Survival points required (120).

"These options…"

"The first one seems to lean toward upgrading its disaster resistance, whereas the second one is perhaps… something like leveling it up to a combat uniform?"

Thump…

Thump…

Su Mo tapped on the surface of the workbench with his fingers, looking at the options that the system gave him in deep thought.

When he was upgrading the raincoat previously, the system gave him the option to upgrade it with an electrical device. This time, however, the electrical device option had been removed, instead being replaced with an invisibility option.

If he just looked at it from the present standpoint, an upgrade in either direction was acceptable and would greatly assist him during his daily routines.

However, if one had to take into account the future direction of the upgrade, then it became a much harder choice.

Of course, the impending disaster was approaching, and being fully prepared for survival was essential. Otherwise, everything else would be meaningless, but if...

Su Mo did not hesitate after he had finally figured it out and said,

"I choose upgrade option… Number two!"

120 points were deducted after he finished his words.

This time, it was not the familiar green light that shone from it. Instead, it was a red light that emitted heat.

The light enveloped the raincoat, and dazzling streaks of glitter and sparks started to appear on the raincoat.

The raincoat transformed under the naked eye; the saggy raincoat material started to improve in texture, and the colors started to disguise themselves, seemingly melding in with the color of the workbench.

"What an awesome ability…"

"The photometric invisibility effects are working even on the workbench."

[Photometric Combat Uniform (Good)]

Description: A combat uniform with outstanding abilities. It is water-proofed, has UV rays resistance, and is slightly wind-proofed, with good heat insulation.

Special abilities: Photometric Invisibility (from certain angles, the special material can bend light and achieve 'Photometric Invisibility'. The special material has a negative refractive index and can transform optical structures.)

Comment: If you could upgrade this, and I mean if, you might be able to open the door to a whole new world!

Su Mo picked up and examined the Photometric Combat Uniform in detail before finding some clues on how it worked.

As long as it was not viewed directly from the front, the Photometric Combat Uniform provided a certain level of photometric invisibility effect, seemingly extending from a 45 degree angle to the rear of the uniform.

It was his first time seeing such an effect. He had not even seen this effect on Earth before.

When Su Mo tried it on himself, he could feel the difference immediately when he moved his arms and legs around.

The previous raincoat fitted perfectly on him, but when moving around vigorously, he still felt his movements slightly restricted.

The upgraded Photometric Combat Uniform was like a thin film that adhered to his skin. It was as if he was wearing a 0.01mm raincoat to battle and its presence could hardly be noticed unless he was focusing on it specifically.

The plastic face shield had also been upgraded to a more advanced softened rubber shell, increasing its breathability and defensive ability to a higher level.

Su Mo figured that he should wear it all the time to get used to it. Finally, he took out the last piece of equipment to be upgraded—ceramic plate armor, and placed it on the workbench to take a good look at it.

[Hunter's Ceramic Plate Armor]:

Description: Made from fine materials, has tidy outlines and an impressive defensive ability. The special aroma of Hidden Herb covers up the hunter's body scent.

First upgrade option: Change the armor's look to a half-body light armor. Slight upgrade in armor materials. Retains the ability to cover up scents and increases defensive ability. Survival points required (105).

Second upgrade option: Change the armor's look to a lower-body light armor. Slight upgrade in armor materials. Decreases the weight of armor and increases defensive ability, Survival points required (130).

Third upgrade option: Change the armor's look to a full-body light armor. Slight upgrade in armor materials. Addition of an electrical supporting device and increased defensive ability. Survival points required (180).

Given the three options, Su Mo did not overthink and confirmed his choice of the third upgrade option.

Electrical energy was a productive resource. No matter what type of electrical device it was, it could transform that resource into kinetic energy. Currently, the cheapest and most convenient resource for this was electrical energy.

With the electrical device, he would turn into someone who could perform magic feats in the eyes of people who were clueless about science.

Without the electrical device, even if the armor was upgraded to the extent where it could slice off iron easily, or even became unusually strong and solid, it could still only be considered as a stronger tool for taking hits and defense.

While it was risky to only depend on a person's strength to fight and battle in the Doomsday wasteland, Su Mo knew which was more important to him.

He tried to pour in the materials he had on hand and, after adding in two pieces of iron, the upgrade cost dropped to 165.

He suppressed the impulse to save on survival points and he gritted his teeth as he confirmed the third upgrade option.

The ceramic plate armor that had been through life and death with Su Mo had accomplished its mission.

The next second, under the green light's tremendous power, it melted into a puddle of black liquid.

The green light was like a pair of unseen hands, starting to knead the liquid into shape out of nowhere. The puddle of liquid soon started to form and take shape, aligning itself with the size and shape of Su Mo's body.

The green light disappeared after three to five seconds.

Bang!

The finished armor fell onto the workbench and let out a cry.

A full-body suit of armor, complete with pauldrons, a pair of h and a rather stupid-looking armor helmet.

"Let's forget about the helmet, even if I wear it, I would still die if someone shot me in the head."

Su Mo examined the sophisticated pattern on the helmet and checked to see if the electrical device was situated behind the helmet before putting it back into the equipment warehouse.

Even if he wore the Photometric combat uniform, the huge helmet would stand out. Wearing it was equivalent to running the risk of getting himself caught by enemies.

"The upper and lower body armor pieces seem light enough. Wearing them shouldn't affect my movements."

The light armor weighed around ten kilograms and could offer enough protection while not affecting his movement and dodging speed in battle.

Su Mo nodded as he pondered on the weight of both light armor pieces.

"Looks like the electrical device was hidden in the boots…"

Su Mo followed the light and examined the light armor boots on the workbench.

Two long devices extended from the front to the back of the boots, but he could not find the battery's location, and neither could it be seen from the outside.

Su Mo searched the boots for a while before finally spotting the charging port on the heel of the boots. He also found the activation switch on the toe of the boots.

"While it's inability to automatically danger and activate could be its largest defect of this electrical device, at least the activation mechanism is convenient enough. All I have to do is point and press my toe to the ground to start the device."

He grabbed the boots and left them on the floor to charge from the electrical supply. Su Mo then started to prepare the final piece of the puzzle.

Customized crossbow arrows!

His current crossbow arrows had been created by the game itself and were sufficient to take on normal kobolds, but this time he was heading into enemy territory. There was no guarantee that he would not encounter stronger enemies.

As such, Su Mo was planning to create the crossbow arrows that were completely different from the average crossbow arrow, improving their lethality.

He headed back to the energy distribution room and plugged in the generator to the before switching on the workbench's power button.

He took a piece of iron and placed it on the bench before Su Mo closed his eyes.

After ten minutes, Su Mo opened his eyes and concentrated on the material in front of him.

The robotic arm on the workbench detected his approaching arm and automatically encased it, becoming one with the arm.

Su Mo switched the left-hand arm to its high-speed cutter mode and sliced the iron into ten even, small rectangular pieces that each measured 18cm in length.

The crossbow arrow that the system had created was of average length, about 25cm, and possessed both lethality and speed.

However, the arrows being of uniform length also meant that they had no special attributes to speak of.

This time, Su Mo was thinking outside the box. He altered the length of the shaft and started to modify it with determination.

According to the system's crossbow arrow design, Su Mo's attention was focused on cutting and grinding, making sure that the width of the broadheads and the fletchings were equivalent.

When wearing the robotic arm, the steadiness of the arm allowed Su Mo to ensure that the accurate requirements of the crafting process would be executed perfectly.

Little sparks ignited and scattered around, hitting the stone wall.

Su Mo was extremely focused during the production process, and his efficiency was quite impressive too.

Only 3 minutes were needed to produce a crossbow arrow and it left aside to cool down.

After finishing 10 of them, Su Mo's back was soaked with sweat.

This type of labor intensive activity required high levels of concentration; a slight mistake would lead to the crossbow arrow being wasted and having to be rebuilt from scratch.

It was thanks to the excellent quality level of the workbench, which increased concentration levels, that ten of the crossbow arrows were successfully produced!
