Six days flew by in a blink of an eye.

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

Thanks to the upgrade of physiological saline, he also gained some new understanding of his own abilities.

It is good to directly upgrade complete items, but in fact, superpowers can also be used to upgrade equipment and semi-finished materials. With continuous live broadcasts, the space backpack has been perfected little by little under the attention and expectations of the audience.

[Void Kangaroo Special Organ Preservation Solution·Modified]

[Level] LV3:84/60000

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

[Evaluation]: You really made me understand what it means to be unable to die, well, literally.

——————————

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

His initial idea was not wrong. The milk of the Void Kangaroo was indeed one of the necessary conditions for the Void Kangaroo to enter hibernation. He mixed part of the milk into the second-level organ preservation solution and upgraded it again, and the experience requirement was slightly increased.

, but it also perfectly blends the two into a new organ preservation solution.

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

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

[Simple constant temperature perfusion device]

【Level】LV3:26/40000

[Introduction]: A simple perfusion device that eliminates various testing equipment and dialysis equipment.

[Evaluation]: You call this a perfusion device?

——————————

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

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

I have to say that the void kangaroo is definitely a model kangaroo. After using these two things to maintain its activity, some of its wounds and exposed tiny blood vessels gradually healed, and then the pouch was allowed to enter through temperature regulation and decreasing nutrient supply.

A stable sleep state.

The ‘material’ that cooperates with the experiment is not a model representative.

At this point, the foundation of the space backpack has been completed.

Lin Yu then used local materials, made simple preparations of void kangaroo fur, and then asked his mother, a 'professional', to sew a prototype of a backpack for him, and then installed the pouch and life-support device at the bottom of the backpack.

.

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

After removing a battery from the hydraulic arm armor, connecting the circuit and stuffing it into a specially set aside fixed pocket in the backpack, Lin Yu smiled with a sense of accomplishment.

Except for the organ preservation solution and perfusion device, the entire backpack can be said to be designed by him. The backpack is also in the style of a backpack, but there is no zipper on it. The mouth of the bag is directly open, and the opening is relatively large, similar to zipping a schoolbag.

It is completely opened, and the space inside the backpack has a V-shaped structure. The bottom is aligned with the void kangaroo's pouch, and the vacant parts are various pipelines and parts.

These parts were made by him using sensors and small motors to assist in wearing the hydraulic arm armor. The arm armor can be automatically attached and fixed, but it is not very convenient to carry the backpack on the back, so small motors and mechanical structures are used to fix the two arm armors and put them on the back.

When he puts it on, he lifts the gauntlet to assist in putting it on.

"Is it finished?"

"Try it quickly and let us see the effect."

"You may not believe it, but these past few days I feel like I'm really watching Iron Man make Mark Armor."

"Feel the same!"

"+1!"

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

Lin Yu himself couldn't wait to give it a try, and readily accepted everyone's suggestions. He first put on one gauntlet, picked up the shield axe, and stuffed it into his backpack.

Part of the space near the pouch is within the scope of influence of the pouch, and the position where the pouch is placed has been specially adjusted. Therefore, the shield ax begins to 'shrink' as soon as it approaches the mouth of the backpack, and the further it is inserted, the smaller it becomes. Obviously it is not

The very deep backpack actually swallowed the entire shield axe, leaving only a small section of the handle protruding from the center of the backpack.

Immediately afterwards, the two hydraulic gauntlets were also stuffed in, but this time they were stuffed in from both sides of the backpack opening at an angle, so that when you put on the backpack, you can just turn your hands over and insert the hydraulic gauntlets.

In the gauntlet.

Click!

The hydraulic arm armor was stuffed until only a small section was left, and a subtle sound of parts moving came from the backpack.

This is the 'auxiliary wearing system' that blocks the hydraulic arm armor. When Lin Yu wears it, it will lift up the hydraulic arm armor through sensors and motors.

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

Lin Yu smiled, brought up the panel of the Xueba System and played 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 truly a self-contained space, so even though it can hold items, its weight has not been reduced.

Fortunately, he always wears the venom suit. After being put under pressure, the lines of the venom suit instantly harden slightly to resist the pressure, which greatly relieves his burden. It is similar to the state of using a hydraulic gauntlet to hold a shield axe, and he is still able to use it.

Within the acceptable range.

Click, click, click!

As the BGM gradually became louder, Lin Yu put his hands back into the hydraulic arm armor. There was a continuous sound of mechanical cuffs. The mechanical structure in the space backpack lifted the hydraulic arm armor up, and the hydraulic arm armor also quickly retracted.

Tightly fixed, the shoulder armor fell down and stuck.

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

"Next is the shield axe."

He raised his forearms flat in front of his chest and made a fist. Lin Yu moved his palms behind his head again, and clenched his fingers tightly on the handle of the mechanical shield axe, which exposed a small section.

He lowered his head slightly, pulled out his hands, and pulled out the mechanical shield ax bit by bit. Due to the 'shrinking' effect of the pouch, it didn't scratch anything. Lin Yu pulled it out smoothly and slashed forward without any delay.

Go down.

clang!
Chapter completed!
