Zheng Qishan's pupils suddenly trembled.
"You are..."
In an instant, he smiled languidly.
"So it's you."
Now his tone of speech was not like addressing a child, but rather like talking to a normal adult.
Clearly, he had already guessed Yun Xiaoxiao's identity.
"You still haven't answered my question. Why did you put heroin in the evolution serum?"
"Did I?"
Zheng Qishan flatly denied it.
[Even if I did, so what? Why should I tell you the reason?
Do you expect me to say I did it to make all the ability users die with me?
Hah, dream on if you think I'll admit that!]
Zheng Qishan didn't know that Yun Xiaoxiao had already read his thoughts.
"I'm very curious, who exactly are you?" Yun Xiaoxiao asked, raising an eyebrow.
This question confused everyone except Zheng Qishan.
They didn't understand why she would ask such a thing.
After all, everyone knew that Zheng Qishan was the leader of Yangcheng Base.
Who else could he be?
Only Lu Chen slightly raised his eyes, as if he had guessed something.
Zheng Qishan narrowed his eyes, coldly looking at Yun Xiaoxiao.
"I am who I am, who else could I be?"
"Oh, is that so?"
Yun Xiaoxiao didn't expose him, but instead asked sharply, "Then was Xin'er's mother really turned into a zombie before you killed her?"
Zheng Xin'er looked up at Zheng Qishan, also wanting to know the truth.
Zheng Qishan's eyes darkened, "This is our family's private matter, what business is it of yours?"
[That old hag, with her face full of wrinkles, I couldn't stand sleeping next to her every day.
If I didn't kill her, who else would I kill? Just looking at her made me sick!]
"Guards, arrest these people! If they resist, kill them on the spot!"
Hearing this, Yun Xiaoxiao's eyebrows lifted.
Seeing people rushing in from outside, she remained calm.
Instead, she looked directly at Zheng Qishan, a cool smile curling her lips as she spoke words that shocked everyone.
"You killed Xin'er's mother because you're not actually Zheng Qishan himself.
You added heroin to the evolution serum because you're old now and won't live much longer, so you wanted all the ability users to die with you, isn't that right?"
Seeing Zheng Qishan's expression full of shock, Yun Xiaoxiao smiled.
That's right, she had deliberately said it out loud.
It was to catch him off guard and make him reveal himself.
Looking at his bleeding chest, he opened his mouth, but Zheng Xin'er pushed the knife in deeper.
He let out a muffled groan, immediately coughing up a mouthful of blood.
"You killed my mother, you deserve this!"
In Zheng Xin'er's eyes, the person before her was not her biological father, but the murderer who had killed her mother.
This sudden turn of events surprised even Yun Xiaoxiao.
She had been planning to act herself.
She didn't expect Zheng Xin'er to beat her to it.
Watching Zheng Qishan slowly close his eyes, everyone had different thoughts running through their minds.
"No one is to speak of what happened here today to outsiders, understood?"
Zheng Xin'er turned her head, sweeping her gaze over all the guards.
In this moment, she exuded an aura of authority.
The guards looked at each other, then all nodded in unison.
"Yes!"
This single word also represented their pledge of loyalty.
The rest of Yangcheng Base remained unaware that their leader had quietly changed.
"Who exactly are you people?"
Zheng Xin'er looked at Yun Xiaoxiao and her companions.
By now, she knew these people were certainly not ordinary.
They had clearly come with a purpose, seemingly targeting her 'fake' father.
There was no need to hide anything, so Yun Xiaoxiao and the others briefly explained about Zheng Qishan sending people to Yun City.
"You're from Yun City?"
Zheng Xin'er was surprised.
"What, don't we look like it?"
"No, I mean, would it be possible to buy evolution serum from you in the future?"
Now it was Yun Xiaoxiao's turn to be surprised.
To be honest, she felt that Zheng Xin'er had acted too impulsively.
If it were her, she might not have killed Zheng Qishan outright.
Instead, she would have kept him under house arrest, forcing him to reveal the method for making the evolution serum.
There would have been plenty of time to kill him afterwards.
But Zheng Xin'er hadn't left herself any room for maneuver, killing him without a second thought.
It was efficient, certainly, but for the people of Yangcheng Base, it might not be a good thing.
Before, they could rely on selling evolution serum to obtain many resources and keep their ability users stronger than those of other bases.
Now that the supply of evolution serum was cut off, they had completely lost their former advantage.
However, what Yun Xiaoxiao admired was Zheng Xin'er's open-mindedness.
She had directly asked about buying evolution serum from them.
She didn't seem to mind at all the huge drop in status from seller to buyer.
