Ruan Ning got straight to the point and said, "I want that colorless and transparent crystal core. Do you have any?"

Gan Lan thought for a moment, then nodded and said, "Yes, but I'll exchange it for as much as you want."

Colorless and transparent crystal cores are easier to obtain than crystal cores with properties. She also saved some of them on her body, and did not use them all to upgrade her abilities. But Kale didn't know how many this person wanted. If the number he wanted was too much, she was afraid she would not be able to give them out for the time being.

Ruan Ning thought about the plot about the crystal core transaction, combined with the actual situation, and said: "I will use my crystal core to exchange for your ten."

Although the redemption ratio seems a bit high, Ruan Ning asked for ten, which is actually not excessive at all, and it can even be said to be a lot less.

After the safe base is established, the exchange rate between crystal cores of the same level in the market will be at least one to twenty.

Now at least five out of ten zombies have evolved. These zombies have crystal cores in their heads. Compared to those rare mutant zombies, killing ordinary evolved zombies is obviously much easier. Similarly, the probability of obtaining colorless and transparent ordinary crystal cores is also greater.

If Ruan Ning wasn't in urgent need of an ordinary crystal core, anyone else would at least trade it for a crystal core with the same properties. No psychic would trade a crystal core with properties for an ordinary one, that would be too bad.

With their trading method, even if the exchange rate is 1 to 20, the person who possesses the mutant zombie crystal core will suffer the loss, not to mention that Ruan Ning only agreed to the exchange for ten this time.

"Okay." Cabbage agreed readily. She also understood that she got the better deal in this transaction. Although she didn't know why this person was willing to exchange crystal cores in this way today, in the end, Cabbage still gave this person all the crystal cores she had, as a thank you for helping him solve her urgent problem.

Ruan Ning raised his eyes and looked at the woman in confusion, but in the end he did not refuse and accepted all the crystal cores.

It seems that there is more than just the crystal core for the male protagonist.

Even these extra crystal cores can be used for treatment several times if she gets injured accidentally in the future.

Ruan Ning's mood had just improved after solving a troublesome problem, but she found someone following her stealthily.

At first Ruan Ning thought she was too sensitive, but later she found that this man kept a distance from her, following her for two blocks. Every time she turned a corner, he turned the same way. If he said he was not coming for her, Ruan Ning would not believe anything.

But her face was now tightly covered, and no one could see her true appearance underneath the mask, so this person was most likely attracted by the backpack on her back.

Ruan Ning knew that carrying a backpack would attract attention, but she had previously thought about exchanging food for crystal cores, and it would be inconvenient without a backpack to cover it. She couldn't just conjure up food out of thin air at the market, right?

Why are these bag snatchers always staring at her... Ruan Ning thought depressedly.

Do people who are shorter and smaller deserve to be targeted? ! If you judge people by their appearance even when stealing, you will get punished sooner or later!

If Ruan Ning had known that this time he would be exchanging crystal cores for crystal cores, he would never have brought a backpack with him.

Ever since she discovered that someone wanted to rob her backpack in public when she and Lin Yang went to look for the male protagonist last time, Ruan Ning knew that this safe zone was much more chaotic than she had imagined.

Ruan Ning met several people along the way, but she did not ask for help, and the person behind her did not leave.

Ruan Ning did not ask for help because he knew that most people in the apocalypse were still ordinary people. Everyone just wanted to live their lives in peace and stability, and no one wanted to cause unnecessary trouble.

It takes strength to do what is right. Some people have the will but not the strength, and even if they want to help, they can only pretend not to see it.

Unless she can meet someone she knows... such as a team member or any one of the three male protagonists.

But now it was too late for her to look for them.

Ruan Ning roughly estimated the distance between her and that person, and felt that the person behind her had quickened his pace and would catch up with her soon.

Instead of waiting for others to save you, it is more reliable to save yourself.

Ruan Ning jogged while observing the situation around her. Finally, she turned away from the direction of the villa, turned a corner, and walked towards a less crowded road.

At the same time, under the cover of her pocket, she took out the gun from the space.

Since she couldn't get rid of the person behind her, she might as well take him to a place with fewer people. In this way, she still had a gun in her hand, and she might be able to turn the passive situation into active and gain a certain degree of initiative.

When there was no one around, Ruan Ning stopped and turned to look behind him.

She also finally saw the true face of the man who was following her.

The man was wearing a grey sports suit and had regular features. If you only looked at his appearance, not many people would believe that he was a robber.

He looks like a decent person, so why did he go down such a wrong path? Ruan Ning couldn't help but complain.

She was just about to take out her gun to see if she could scare the man away when she heard the man she thought was a "robber" say excitedly, "Ruan Ning, it's really you!"

Hearing his slightly excited tone and the content of his words, Ruan Ning's first reaction was how did this person know her name. Her second reaction was: "Who are you? Do we know each other?"

Perhaps the doubt in Ruan Ning's eyes was too obvious, so the man continued: "You don't recognize me? I'm Qin Renhao, the boy from the class next to yours. One time when you passed by the basketball court, I accidentally hit you on the head with a ball, and finally sent you to the infirmary... Do you remember?"

"Qin Renhao?" Ruan Ning thought for a long time before finally remembering who Qin Renhao was and what he looked like.

...It turns out that this person is actually the original owner's classmate at No. 1 Middle School.
