The man and his companions, however, believed that Yun Xiaoxiao was simply talking nonsense.
"You took our crystal cores, and today you must give us an explanation! Otherwise, don't blame us for..."
"What, you want to use force?" Suddenly, Nie Yizhou's voice came from behind.
Everyone turned to look and saw him walking towards them with Xiao Feng and Ling Jing.
They stood beside Lu Chen and Mu Yang, with Yun Xiaoxiao right in the middle.
As these people stood there, the atmosphere became incredibly intense.
The man who had been about to make threats immediately swallowed his words.
If this were any other base, he wouldn't have backed down so easily.
But these people also had evolution serum.
Moreover, these individuals looked like they weren't to be trifled with.
This was also someone else's territory.
If a fight broke out and everyone inside came out, they could drown them with just their spit.
He was convinced there were many people inside the base.
After some thought, the man had to suppress his dissatisfaction.
"Let's go," he said, glancing at Yun Xiaoxiao and the others, deciding to retreat for now.
Watching the two cars leave, Yun Xiaoxiao didn't try to stop them.
The fact that they were so eager to send people here for evolution serum made her wonder if, as she suspected, their leader might also be a reborn individual.
So...
What kind of person were they?
Strangely enough, Yun Xiaoxiao felt a bit excited.
It turned out she wasn't the only reborn person in this world.
So, was this person good or bad, friend or foe?
She had tricked them once, so what would they do next?
Her actions today, besides teaching that arrogant man a lesson, were also to gauge the attitude of the person behind all this.
If they could come in person, that would be ideal.
It would save her the trouble of making the trip herself.

In the evening, Zhong Mingsheng came to find Yun Xiaoxiao.
He handed her two analysis reports.
"They have basically the same components, but there are many subtle differences," Zhong Mingsheng said slowly.
"This one has cleaner components, with fewer impurities.
The other is obviously much cruder, not refined enough.
Most importantly..."
Zhong Mingsheng paused, his eyes growing serious.
Seeing this, Yun Xiaoxiao became more attentive.
"Grandpa Zhong, what's most important?"
Zhong Mingsheng continued in a grave voice, "This one contains traces of heroin. If consumed in large quantities, it can be addictive. Once addicted, it would be very troublesome to quit."
Hearing this, Yun Xiaoxiao frowned.
"If someone becomes addicted, what symptoms would they show?"
"Mild cases might experience hallucinations, severe cases could suffer fatal damage to their bodies."
"What happens if someone addicted stops using it?"
"They either forcibly overcome the addiction, but most people can't endure such painful torment.
Or they go mad, experience various hallucinations, and might eventually commit suicide."
Hearing this, Yun Xiaoxiao's brows furrowed deeply.
Why would they add drugs to the evolution serum?
They didn't know about her existence before, nor did they know she had better evolution serum.
In other words, their evolution serum could have been considered a monopoly before.
So even without adding this addictive drug, they could have made a fortune.
Why go to such lengths?
Yun Xiaoxiao couldn't quite understand this.
But based on this alone, she knew this person couldn't be her friend.
Just imagine, if she wasn't here.
As time passed, their evolution serum would surely spread to every base.
Then all the ability users might end up consuming this poisonous liquid.
What was their purpose?
To make all ability users addicted, unable to leave their evolution serum, willing to fight to the death for them?
Or did they want to destroy these ability users?
Or was it something else entirely?
Whatever the reason, this person's intentions were utterly despicable!
Thinking about this, she was somewhat distracted during dinner that evening.
Halfway through the meal, Ci Wan and the others returned.
They all looked a bit disheveled.
Ci Wan wordlessly placed a large bag in front of Yun Xiaoxiao.
Seeing Yun Xiaoxiao look over, she pursed her lips.
"Crystal cores," she said.
After a moment, she added, "Little sister Xiaoxiao, there are about three hundred level-one zombie crystal cores in here, and two level-two cores. I have a request, if I may."
"Go ahead, Sister Ci Wan."
"It's like this. If nothing unexpected happens, we'll be going out to kill zombies every day from now on.
But this way, the danger will also be great.
I was wondering if we could exchange some of these crystal cores for evolution serum first.
For the cores we owe you, we can pay them back bit by bit each time?"
Ci Wan said, somewhat embarrassed.
"If you mind, we can also pay interest," she quickly added.
Yun Xiaoxiao smiled lightly, "It's fine, let's do as you suggested. No need for interest."
Hearing this, Ci Wan's eyes filled with gratitude.
For the next two days.
The base continued as usual, with everyone performing their duties, living earnestly and diligently.
Yun Xiaoxiao and Lu Chen's group also went outside to capture three zombies and bring them back.
Zhong Mingsheng and the others said they needed zombies for experiments.
The vehicle they used to capture zombies was a large truck specially modified by Mu Yang.
Yun Xiaoxiao didn't choose to keep the zombies inside the base.
Instead, she had Nie Yizhou and Liu Yi build an empty house outside the base.
It was specifically used to hold zombies.
This way, they could avoid the unlikely situation of zombies suddenly escaping and harming ordinary people in the base.
Although the chances of zombies escaping were extremely slim, as long as there was a possibility, she wanted to eliminate it.
Since the people from Yangcheng Base came, no one else had come to buy evolution serum.
This made Yun Xiaoxiao doubt herself a little.
Was her dream of sitting back and collecting crystal cores about to shatter?

Yangcheng Base.
"They were really that unreasonable?!" Zheng Qishan said with a dark face, looking displeased.
Several people nodded.
Zheng Qishan's expression grew even more gloomy.
The other side was clearly trying to extort them!
"You say it was a five-year-old child talking to you the whole time?" he asked, frowning.
"Yes, it was a five-year-old girl. She was quite cute, but her mouth was very sharp."
"She said she researched this evolution serum herself?" Zheng Qishan asked again.
"Yes, she said it was very simple, but in my opinion, they were just making excuses. How could a five-year-old child possibly create something as powerful as evolution serum?"
"Who says a five-year-old can't do it."
Zheng Qishan raised an eyebrow, his eyes deep and thoughtful.
If the other person was a reborn individual like him, then it would make perfect sense.
