The two sisters shared some snacks and drank half a tube of nutrient solution before they felt something in their stomachs, and the burning and spasming sensation in their stomachs caused by hunger finally disappeared.

After a hearty meal, with the lingering aroma in my mouth, my body, which usually relies on nutrient solutions for sustenance, felt incredibly satisfied.

Fang Qingdai started to feel sleepy. Seeing that the little girl's head was also nodding, she simply pulled her into her arms, and the two of them squeezed together on the narrow wooden bed and fell asleep.

Fang Qingdai did not sleep soundly.

The wind howled outside the shack, accompanied by the sound of sand hitting the wooden planks. Sand and dust would even blow into the shack from time to time through the leaky planks, waking Fang Qingdai up several times.

The wind finally died down a bit in the middle of the night, and I thought I could finally get some restful sleep.

As a result, the roars of beasts began to come from afar, mixed with the howling wind, and just listening to them was enough to send chills down your spine!

Fang Qingdai couldn't sleep at all this time. She turned over, glanced at Qingluan who was finally sleeping soundly in her arms, sighed, and gently put the little one on the bed.

As soon as Qingluan left Fang Qingdai's embrace, she frowned and curled up uncomfortably, but thankfully she did not wake up.

Fang Qingluan was incredibly soft-hearted. She gently patted the little girl's back until the girl relaxed her brow and fell asleep again. Only then did she tiptoe out of the hut.

The wasteland was dark, like a bottomless abyss, where countless man-eating beasts lurked!

Fang Qingdai frowned and looked back. She saw the bright, sun-like lights on the top of the eggshell fortress, which barely covered the shack area outside the city, and she felt slightly relieved.

A team of superhumans patrols the safe base every day, so there are basically no monsters around the base.

Squeezing out of the base to eke out a living is actually being under the base's protection, at least offering some degree of security.

But Fang Qingdai could not find peace of mind no matter what.

Those were the strange beasts that were taller than houses and bigger than trucks, ferocious and bloodthirsty, as described in the original owner's memories; and those zombies that had human forms but ate people and gnawed on flesh.

Or perhaps those mutated plants that have evolved intelligence and begun to absorb nutrients from flesh and blood...

Each and every one of these was a danger that Fang Qingdai, who lived in a peaceful country, had never seen or heard of!

Especially since the original owner had limited abilities and couldn't secure a good location, he could only settle with his younger sister on the outermost edge of the shack area. Once the door was moved, they would be faced with an endless wilderness.

In other words, if any dangerous creature manages to slip through the net and finds its way by scent, Fang Qingdai's shack will be the first to be attacked!

Fang Qingdai frowned, thinking to herself that this definitely wouldn't work. The most important thing right now was to move!

Even if they can't move back into the city, they should at least move to the inner part of the shantytown. The closer they are to the base, the safer they will be!

Otherwise, she would have been a weak woman with no strength to even kill a chicken, and she would have had to die if she encountered a strange beast!

After thinking for a moment, Fang Qingdai returned to the shack and took out the snack bags she had eaten yesterday.

Concentrating and trying the method from yesterday, Fang Qingdai successfully restored the small bread to its original state!

She was greatly encouraged and carefully calculated the time. It had been about eight hours since she last used her ability.

As expected, the skill slowly recovered its energy.

Fang Qingdai then tried the second one, but found that her head started to hurt like it was being pricked with needles again, and she couldn't use the skill!

She sat on the wooden box, deep in thought. If eight hours could only restore the energy of one item, then the energy accumulated over twenty-four hours in a day would be just enough for three items.

In other words, I used up all my energy in one go yesterday.

This skill level is taking way too long to level up!

If things continue like this, using the rewind skill every day will only ensure that the two sisters don't starve to death, but they won't be able to accumulate any more wealth!

Fang Qingdai originally wanted to use her skills to get some good stuff, and then use the resources to clear a path so that the two sisters could move to a new place!

She was a little discouraged, but quickly adjusted her mindset.

This cheat ability is enough for me to survive with Little Azure Phoenix; one shouldn't be too greedy...

Yeah, right!

Fang Qingdai was not giving up. She tried every minute, spending a whole day in the shack conducting experiments. She finally concluded that it did indeed take about eight hours to restore the energy of an item!

Furthermore, there are limitations on the size of the items. For example, Fang Qingdai can easily restore yesterday's chocolate after eight hours.

But the third time, when Fang Qingdai tried to recreate the large plastic bag that she couldn't tell what it was, she failed to successfully bring the item back to its original state.

That big plastic bag was about the same size as an extra-large bag of potato chips, about three times the size of the small bag that Fang Qingdai restored yesterday.

But after Fang Qingdai used her skill for the third time and successfully retraced the events of yesterday's bag of potato chips, she vaguely felt that the invisible and intangible energy bar in her brain had increased slightly!

It felt very mysterious, but Fang Qingdai could sense that this thing was similar to an experience bar in a game, and that she would gain a little bit of experience every time she used a skill.

Once you've accumulated enough experience, your skills will level up, and your ability to rewind will definitely be more powerful!

Fang Qingdai understood the situation and became less panicked.

Since she was still injured, she spent the last few days holed up in the hut with Qingluan, using the Rewind skill to farm food and increase her experience bar.

Finally, three days later, Fang Qingdai successfully restored the fourth item!

Fang Qingdai retrieved the nutrient solution from that tube!

She was so excited she almost cried. Her head was throbbing from all the repeated attempts over the past few days, and she finally managed to accumulate enough energy to upgrade!

Looking at Fang Qingdai's teary eyes, Qingluan hesitated and pushed the potato chips in her hand towards Fang Qingdai's hand.

"Sister, you eat."

The little girl blinked, her worried yet dependent gaze bringing Fang Qingdai back to her senses.

"I'm not hungry. I've had enough calories from the chocolate. Qingluan, eat more. You need to grow tall so you can grow taller!"

Fang Qingdai wasn't lying to Qingluan; eating most of that chocolate bar did indeed provide enough calories to sustain her for the day.

It's just that my stomach feels empty and I don't feel full, which is not very comfortable.

However, Fang Qingdai often dieted in modern times, so this bit of hunger was nothing to her.

The priority now is to ensure the sisters' survival, quickly save up some supplies, and find someone to "buy" a good location to move!

Fang Qingdai hadn't been sleeping well for the past few nights. Every night, listening to the howling of wild beasts, her heart felt like it was about to stop working!

Now that she finally had the ability to trace back one more item, Fang Qingdai rummaged through the wooden box and found several empty nutrient solution tubes, thinking that she would store enough supplies in the next few days!

Chocolate bread rolls and the like would be too conspicuous in a resource-scarce wasteland, so Fang Qingdai didn't plan to take them out, at least not until she had the ability to protect herself.

The only thing that can be traded is nutrient solution.

However, Fang Qingdai didn't have much time. That very night, the ferocious roars of the beasts grew more frequent and louder, seemingly rushing towards the base...
