Build a doomsday base, starting from the infinite supermarket.

After Song Zhi left.

Shen Ling returned to the ward with a bottle of water, which Yan Wushuang needed because he was thirsty.

Next is some time for the two of them to be alone.

Yan Wushuang planned to tell Shen Ling that he wanted to take her away.

Just like Song Zhi's situation, Yan Wushuang thought Shen Ling would refuse to leave with him, or would hesitate for a while.

But he didn't expect that when Shen Ling heard him say the word "leave", she nodded and agreed immediately.

As a result, Yan Wushuang didn't even have the time to say what he had prepared in his mind.

Song Zhi agreed readily, and Shen Ling agreed equally readily.

In the end, he, the one who spoke, seemed indecisive.

But it was a good thing to just agree to it. He could feel relieved for a while and concentrate on recovering from his injuries.

-

The three days passed quickly.

Yan Wushuang’s health has almost recovered, and it’s time to say goodbye.

Song Zhi got up very early that day, before dawn.

She took out the portable storage device that Si Qing had given her before, put a few shelves in it, planned the area, and started the plan to fill it up.

She knew that Shen Ling's departure was inevitable, it was just a matter of time.

Although she was reluctant, she could only respect it.

After all, she didn't know Shen Ling's past, nor was she clear about the relationship between her and Yan Wushuang.

She could only do her best to make Shen Ling live a better life in the days after she left her.

At least I don’t have to worry about food and daily necessities.

Her abilities are limited now, so she can only do this much.

Song Zhi first filled a whole shelf with snacks and Shen Ling's favorite chocolate. He got several boxes of each flavor and stacked them high.

Not to mention the instant food products, rice noodles, hot and sour noodles, etc., were all packed as much as possible. In order to ensure that these things could be cooked, Song Zhi also added a few more pots and threw them aside.

When you go out, you must not go hungry.

Of course, daily necessities are also indispensable, such as paper towels, toiletries, etc. Song Zhi has prepared a sufficient amount for five years, and sanitary napkins, Song Zhi has also prepared some.

Although Shen Ling is still young now, she will grow up eventually and can be used when she has her period.

She was not sure whether she would meet Shen Ling again in the future, so she had to make some preparations in advance.

Food accounted for the majority of the space, followed by daily necessities. In the remaining corners, Song Zhi also stuffed a lot of clothes, little skirts, and various medicines.

I don’t know what the medical resources are like at the base where Shen Ling is. Song Zhi just hopes that Shen Ling will be safe in the future and will not have the opportunity to use these drugs.

"Sister? You got up so early!"

After getting up and washing up, Shen Ling went to Song Zhi's room first, but after knocking for a long time, the door was not opened.

At this time in the past, Song Zhi would still be sleeping and would be woken up by her. She was like a thoughtful human alarm clock.

But after knocking for a long time, there was no movement in the room, and Shen Ling realized that Song Zhi might have gotten up.

The lights in the supermarket at the end of the corridor were on, so she guessed that Song Zhi might be in the supermarket.

This time, I found Song Zhi in the supermarket.

"Well, you are leaving today, and I plan to pack some things for you to take with you." Song Zhi said gently when he saw Shen Ling.

When Shen Ling heard Song Zhi's words, she suddenly felt a little reluctant.

These past few days she had been trying hard not to think about leaving, thinking that if she didn't think about it, she would feel better.

But no.

When she heard her sister say "I'm leaving", her chest suddenly felt uncomfortable and she had trouble breathing.

She obviously knew that her body was healthy and there would be no problem.

She quickly ran to Song Zhi and hugged him in her arms.

"Sister~"

There was a hint of crying in Shen Ling's soft voice, and she buried her little head tightly in Song Zhi's arms.

Song Zhi had no choice but to temporarily give up what he was doing, slightly bent down, and hugged Shen Ling to coax her.

"What's wrong, Lingling, are you unhappy? Sister is here, you can tell her if you are unhappy."

Shen Ling continued to hug Song Zhi, hugging her tighter and tighter.

She hummed for a long time before she called out "Sister~"

She didn't want to leave her sister, nor did she want to be separated from her sister.

But she couldn't say that she had a task and a mission that she needed to accomplish, and that this was what she had to do.

And…she was afraid.

I was afraid that if I said “I don’t want to leave” to my sister, I would lose control of my emotions and wouldn’t be able to hold it in any longer.

Shen Ling repeated "sister" over and over again without saying any extra words.

Song Zhi held the person in his arms with heartache, stroking her back slowly to comfort her.

"Lingling, be good. Sister is here."

A long time passed, so long that the sky outside was already beginning to turn white.

Shen Ling came out of Song Zhi's arms with red eyes.

The dark blue pupils turned into light blue, and after a few breaths, they slowly returned to normal.

Looking at the place she had just touched, it was already wet.

"I'm fine, sister. I'm sorry for making you worry."

Shen Ling's voice was so light that it seemed to be blown away by the wind, making it sound unreal.

But her eyes were unusually firm.

Song Zhi knew that she was ready.

This was the first time in Shen Ling's life that she had experienced such strong emotional fluctuations, a mixture of reluctance and sadness, and a collision of reason and desire.

Even after that, when she was abandoned by everyone and left among thousands of zombies, she never had this feeling again.

Song Zhi stared at Shen Ling for a while worriedly, and after making sure that she was fine, he continued to load supplies into the storage device.

While Song Zhi was doing this, Shen Ling was watching from the side.

He said nothing, but looked extremely serious.

She wanted to write down everything about her sister so that when she couldn't see her sister in the future, she could recall it bit by bit.

Even if I can't see my sister again, it should be of some use if I only use memories.

Shen Ling thought so naively.

-

The storage space was limited, but luckily she had two.

Another one, Songzhi was filled with bottled water and lined up neatly.

After experiencing the drought in the previous two months, Song Zhi was worried that it would happen again at the base where Shen Ling was located, so he took precautions.

After all the supplies were packed, Song Zhi handed the two portable storage devices to Shen Ling.

"These are what my sister prepared for you. There are all kinds of things in them. When you need them, just press this button and use your consciousness to control them, and you can take out the supplies."

"Use it in front of your sister first and show me."

Song Zhi handed the thing to Shen Ling, but was afraid that Shen Ling would not know how to use it, so she asked Shen Ling to use it in front of her.

Shen Ling nodded obediently and agreed, and under Song Zhi's gaze, she took out a piece of chocolate and put it in her hand according to the method Song Zhi had just said.

"Here, sister, this is your favorite strawberry flavored chocolate."

Shen Ling put the piece of chocolate in Song Zhi's hand and closed Song Zhi's hand forcefully.

After that, she took the two portable storage devices and left the supermarket.

Outside the supermarket, Yan Wushuang was already prepared and waiting there.

Seeing Shen Ling coming out, he waved to her excitedly.

Shen Ling nodded in agreement, then turned to Song Zhi and said the last words.

"Goodbye, sister."

Song Zhi didn't answer until she saw Shen Ling's back disappear in front of her, then she murmured.

"Goodbye, Lingling."
