Little White is now the size of an adult Labrador Retriever.

Its entire body is black, shiny, thick, and hard, forming the first and most powerful line of defense for its body.

Its strong and beautiful muscle lines contain the terrifying explosive power unique to felines.

The claws, hidden beneath thick paw pads, gleamed coldly, exuding a formidable aura.

The current Xiaobai could easily take on an adult male in a head-on fight.

The silly dog, Xiao Hei, is even more outrageous.

Who would have thought that the little dog that used to shiver in the cold wind would grow to the size of a wild wolf king?

Now it has expanded even further, exceeding the size of the world's largest "North American gray wolf".

The height of the four-legged stance was already level with Liu Kai's chest.

Even carrying Liu Kai, who weighs 200 pounds, he can still run easily across the snowfield.

If it weren't for that wise gaze, he would truly have an imposing presence.

As the cat and dog crawled into the back of the snowmobile, the large tires visibly deflated.

The snowmobiles, which were originally quite spacious, now seemed very crowded.

Looking at the two of them, Liu Kai was at a loss for what to do.

The underground fortress was indeed spacious enough, but it was designed with the human body size as a reference for the activity space.

Black Cat Xiaobai is alright.

However, if Xiao Hei is placed on the second living level, it will obviously be too cramped to move around.

In addition to their enormous size, they also became incredibly energetic.

Running around in this forest every day is a great way to expend energy.

But what if we go back to the bunker?

Liu Kai suddenly recalled the messy scene from before and immediately shook his head vigorously.

We can't let them stay on the living floor and wreak havoc on the furniture!

The first level of the bunker serves as a shooting range and also functions as a parking and charging station.

Although Liu Kai can rely on his spatial abilities to hit the target every time.

But shooting, a sport enjoyed by men, is also an excellent pastime during the cold snap and the end of the world.

You can't move here.

Similarly, the fourth layer of equipment cannot be touched.

That leaves only one option.

With improved physical fitness, ordinary exercise is no longer effective.

The third floor, which was then converted into a swimming pool, also became useless.

It can now be converted back into an activity area.

It's perfect to leave some discarded tires, furniture, metal frames, and the like, letting cats and dogs that love to destroy things run rampant.

Liu Kai quickly made up his mind and prepared to head down the mountain.

After thinking about it, he decided to take out the X01 powered exoskeleton and put it on.

Although it now has many capabilities that are superior to exoskeletons.

But whether it's singing, dancing, rapping, or playing basketball, all these actions require consuming one's own energy.

Having such a "high-tech prosthetic limb" to help save effort in normal times will make you more secure in case of emergencies.

This unintentional decision suddenly opened a door to a new world for Liu Kai.

When he focused his attention on the exoskeleton in the storage space.

A familiar impulse instantly surged into my mind!

"this?!"

Liu Kai's eyes suddenly widened, his face filled with disbelief.

After carefully sensing the exoskeleton again for a while, I finally confirmed that it wasn't my imagination.

It was an impulse.

An urge to devour!

Just like his impulse to devour the pen nib back then.

This time, however, the object he craved was not the metal of the exoskeleton.

It was the small plutonium-238 radioisotope generator.

The generator constantly emits alpha radiation, which is captured by internal equipment and converted into electrical energy to power the exoskeleton.

Once stored in the storage space, the object's time flow ceases.

Those radioactive particles that were moving at near the speed of light were also rendered stationary in space.

But when he controls the flow of time in this part of the space to return to normal.

To my surprise, I made this discovery.

The storage space can absorb these radioactive particles!

The same principle applies.

The time it takes to control the storage space is accelerated, and the decay of plutonium-238 becomes more intense.

At the same time, more high-energy alpha particles are released.

Liu Kai was so engrossed in the sensation of devouring particles that time flew by.

To the outside world, it only lasted a short 3 minutes.

However, for the isotope generator of the powered exoskeleton, three days passed directly.

After a large number of radiation particles were completely absorbed, Liu Kai felt a tingling sensation throughout his body.

It felt like ants crawling on my body, or like someone tickling me with a feather.

He was so frightened that he instantly snapped out of that instinctive impulse.

He immediately stopped his reckless action, his whole body drenched in a cold sweat from the shock.

He couldn't help but curse himself for being so impulsive.

That's nuclear radiation, something everyone tries to avoid.

Who knows if being swallowed by the storage space will affect me?

If you get a severe radiation sickness, even a god couldn't save you!

Liu Kai quickly suppressed his unease, and a highly accurate scan enveloped every inch of his body.

Until nanometer-level precision probes scan the entire body.

Liu Kai finally breathed a sigh of relief, and the worry on his face turned into a hint of joy.

There were no abnormalities in the body, and no signs of broken DNA strands in the cells.

Not only that.

He also keenly sensed that the physical and spatial abilities that had completely stopped strengthening seemed to be loosening again.

As expected, the enhancement of physical and spatial abilities has not yet reached its limit!

"Could the next stage of enhancement be the absorption of radiation?"

A bizarre yet highly probable idea popped into Liu Kai's mind.
