My items can be upgraded

How did this evaluation come about?my subconscious?Or is it the audience emotion contained in the experience?

Excluding the taunting nature, the evaluation of the upgrade ability reminded him.

The normal saline concentration of amphibians is 0.67%~0.70%, and that of mammals is 0.85%~0.9%. Kangaroos are mammals, so 0.9% is correct in general terms, but dimensional creatures like void kangaroos obviously cannot. In terms of common sense, he made a common-sense mistake.

Silently remembering this lesson, Lin Yu started upgrading again.

A faint blue brilliance flashed, and the appearance of the saline in the glass tank remained unchanged, only the description changed.

【Void Kangaroo Special Organ Preservation Solution】

[Level] lv: 340/5000 (can be upgraded ↑)

[Introduction]: The organ preservation solution specially formulated for the void kangaroo can maintain its cell activity for a long time.

[Comment]: Doctor, doctor, I think I can still save it, can you put my head back on?

Chapter 1 backpack completed

Six days passed in the blink of an eye.

At this time, Lin Yu's workshop had changed drastically, with a lot of equipment and materials piled up, and on the table at the far end of the workshop, a grey-yellow backpack had begun to take shape.

With the upgrade of normal saline, he also had a new understanding of his abilities.

It is good to directly upgrade complete items, but in fact, abilities can also be used to upgrade equipment and semi-finished materials. Relying on successive live broadcasts, the space backpack is almost perfected little by little under the attention and expectation of the audience.

[Void kangaroo dedicated organ preservation solution modification]

【Level】lv3: 84/60000

[Introduction]: The organ preservation solution specially formulated for the void kangaroo can stimulate the dormancy mechanism of the void kangaroo and provide the nutrients necessary for survival, so that the isolated organs are in an active state for a long time.

[Comment]: You really let me understand what it means to be unable to die, um, literally.

This is a third-level organ preservation solution. The only difference is that he didn't directly upgrade it, but tried to add the extracted void kangaroo milk into it.

His initial thinking was not wrong. The milk of the void kangaroo is indeed one of the necessary conditions for the void kangaroo to enter a dormant state. He mixed part of the milk into the second-level organ preservation solution to upgrade again, and the experience requirement was slightly increased. , but it also perfectly mixed the two into a new organ preservation solution.

Of course, there is a more important point, that is, the mixed and upgraded organ preservation solution can be affected by the repairing effect of experience. As long as you have experience, you can replenish it endlessly, saving him the trouble of analyzing the composition and structure of milk.

Then there is the thickness of an arm, with pipelines and metal covers at both ends, and a cylinder with a transparent shell in the center.

【Simple constant temperature perfusion device】

【Level】lv3: 26/40000

【Introduction】: A simple perfusion device that excludes various testing equipment and dialysis equipment.

[Evaluation]: You call this a perfusion device?

He made and upgraded it with a miniature water pump and some pipelines. It is very similar to a disposable perfusion device. It does not have any testing or dialysis. All parameters need to be adjusted and set by yourself. To put it simply... this thing is still a water pump.

Its only purpose is to connect part of the blood vessels of the void kangaroo, and then let the organ preservation fluid replace the blood of the void kangaroo to achieve self-circulation and constant temperature.

I have to say that the void kangaroo is definitely a well-deserved model kangaroo. After using these two things to maintain its activity, some of its wounds and exposed tiny blood vessels gradually healed. A stable dormant state.

Isn't such a 'material' that fits the experiment a model?

So far, the foundation of the space backpack has been completed.

Afterwards, Lin Yu took materials from the local area, used the fur of the void kangaroo for simple tanning, and then asked his "professional" mother to sew a prototype of a backpack for himself, and installed the baby bag and life support device at the bottom of the backpack. .

"Okay, the assistive wearing system is also completed."

Lin Yu put a battery removed from the hydraulic gauntlet and connected the wires into a specially reserved fixed pocket in the backpack, and Lin Yu smiled with a sense of accomplishment.

Except for the organ preservation solution and the perfusion device, the entire backpack was designed by him alone. The backpack is also in the style of a backpack, but there is no zipper on it, and the mouth of the bag is directly open, and the opening is relatively large, similar to zipping a schoolbag It is fully opened, and the space inside the backpack presents a V-shaped structure. The bottom is aligned with the void kangaroo's pouch, and the empty parts are various pipelines and parts.

These parts are made by him with sensors and small motors to assist in wearing the hydraulic gauntlets. The gauntlets can be attached and fixed automatically, but it is not very convenient to put the backpack on the back, so he uses small motors and mechanical structures to fix the two gauntlets. When he puts it on, he lifts the gauntlet up to assist in donning.

"Completed?"

"Try it quickly, let's see the effect."

"You may not believe it, these days I feel like I'm really watching Iron Man making Mark armor."

"Same feeling!"

"+1!"

Hearing the news of the completion, not only Lin Yu felt a sense of accomplishment, but also the audience who watched the space backpack being completed bit by bit through the live broadcast were also elated.

Lin Yu himself couldn't wait to try it out, and he readily accepted everyone's suggestions. First, he put on a gauntlet, picked up the shield ax and stuffed it into his backpack.

Part of the space near the nursery bag is within the range of influence of the nursery bag, and the position of the nursery bag has also been specially adjusted, so the shield and ax will start to 'shrink' as soon as it approaches the backpack mouth, and the more it is stuffed in, the smaller it is, obviously not The very deep backpack actually swallowed the entire shield axe, leaving only a small section of handle protruding from the center of the backpack.

Immediately afterwards, the two hydraulic gauntlets were also stuffed in, but this time they were inserted obliquely from both sides of the backpack opening, so that when you put on the backpack, you can turn your hands over to fit into the hydraulic gauntlets. In the gauntlet.

click!

After stuffing the hydraulic gauntlet to only a small section, there was a slight sound of parts moving in the backpack.

This is because the 'Auxiliary Wearing System' stuck the hydraulic gauntlet, and when Lin Yu put it on, he would lift up the hydraulic gauntlet through sensors and motors.

"Okay, let's try the fruits of our labor."

Lin Yu smiled, called up the Xueba system panel to play the bgm of Iron Man's first test flight, and then put the backpack on his back.

Slightly heavy.

The void kangaroo's pouch is not really a self-contained space, so even if it can hold items, the weight has not been reduced.

Fortunately, he wears the venom suit all the time. After being under pressure, the lines of the venom suit harden slightly to resist the pressure, which greatly relieves his burden. Acceptable range.

Ka Ka Ka Ka Ka Ka!

As the bgm gradually increased, Lin Yu put his hands back into the hydraulic gauntlets, and there were bursts of machine sounds. The mechanical structure in the space backpack lifted the hydraulic gauntlets, and the hydraulic gauntlets were also quickly retracted. Tightly fixed, the shoulder armor fell and the cover was stuck.

In just a second or two, when Lin Yu pulled out his arms again, the hydraulic gauntlets had already properly covered his arms.

"Next is the shield and axe."

Raising his forearm in front of his chest and making a fist, Lin Yu moved his palms behind his head again, and tightly clenched his ten fingers on the handle of the mechanical shield ax with a small section exposed.

With his head lowered and his hands pulled out, the mechanical shield ax was pulled out little by little. Due to the 'shrinking' effect of the pouch, it didn't scratch anything. It was pulled out smoothly by Lin Yu, and he slashed forward without any delay. down.

clang!
