Zheng Qishan's face grew even darker as he thought about it.
In his previous life, he was a core member of the research institute, young and promising.
But because he had a delicate, almost feminine appearance, he was coveted by a perverted superhuman in the base.
He was harassed every day and eventually died from abuse after resisting.
Ironically, the superhuman was so powerful because he had drunk the evolution serum that Zheng Qishan had helped create.
And all the hard work he put into making the evolution serum ended up nurturing the scum who killed him!
His heart was filled with extreme resentment and humiliation.
Until the moment he closed his eyes, he was still roaring in his heart.
If he could live again, he would definitely kill all those despicable superhumans!
Unexpectedly, he really did get a second chance at life.
However, why did he have to be an old man with one foot already in the grave?!
He was unwilling!
Why couldn't he be reborn young?
Since he didn't have much time left, those superhumans shouldn't expect to live either.
If those superhumans died, no one would be able to deal with the disasters that kept coming.
If he was going to die, everyone else could die too!
Let everything be destroyed!
So, he made the evolution serum.
And he added heroin to it, wanting to get those superhumans addicted to drugs.
He knew what superhumans craved the most.
Wasn't it power?
As long as they bought his evolution serum, they would keep buying and drinking it.
By the time he died, he would either give them a lethal dose or simply cut off the supply, and countless people would die with him!
The thought of that scene made him incredibly excited.
But why was there another reborn person?!
And that person could also develop evolution serum.
The serum was even purer and more effective than his!
What was even more infuriating was that the other person was reborn as a five-year-old child, just starting life with beautiful years ahead to enjoy.
And he was reborn as an old man on the verge of death.
Why?!
This wasn't fair!
Zheng Qishan clenched the cane in his hand, filled with resentment and jealousy.
No one could stop his plan!
Not anyone!
"Announce to the public that our evolution serum is only sold for forty zombie crystal cores of the same level, and..."
His eyes darkened, "Send someone to secretly watch near Yun City Base. If anyone goes there to buy evolution serum, disguise yourselves as from Yun City and assassinate them.
It doesn't matter if you kill them or not, as long as they know you're from Yun City."
He didn't believe anyone would dare to go to Yun City to buy evolution serum anymore!
---
Yun Xiaoxiao waited and waited, and finally, another batch of people came to buy evolution serum.
But unexpectedly, the effect of this serum was much better than the one from Yangcheng!
He immediately called out to someone.
"Bring out the crystal cores."
As soon as he finished speaking, one of the men behind him stepped forward.
Then, the man magically produced several sacks filled with items.
Yun Xiaoxiao's eyes widened.
This must be a space ability user.
It wasn't surprising for a big base like Rongsheng to have a space ability user.
What surprised her even more was that Long Zhe had also awakened an ability.
No wonder Jiang Huai brought him along this time.
He probably wanted Long Zhe to gain some experience.
"Please wait a moment, I'll go get it," Yun Xiaoxiao said and went back inside.
She didn't invite Long Zhe and his group in to sit.
Seeing the door close immediately, Jiang Huai couldn't help but chuckle.
He had just praised her for being thoughtful, but it seemed he spoke too soon...
However, he didn't take it to heart.
After all, she was just a child; there was no need to expect too much from her.
After a short while, Yun Xiaoxiao returned.
She handed all the evolution serum to Jiang Huai.
"Count them, they should be enough."
Jiang Huai nodded and handed them to the person behind him.
After counting, the person confirmed, "No problem."
Jiang Huai pointed to the sacks.
"The crystal cores are all in there. Do you want to count them?"
"Sure."
Yun Xiaoxiao tipped the sacks over and started counting one by one.
Her serious little face looked like that of a money-loving little miser.
Everyone waited patiently for her to finish.
"Yes, they're enough."
"If you need more, feel free to come back."
Yun Xiaoxiao waved with a smile, "Alright, now that the deal is done, goodbye and safe travels."
Long Zhe and Jiang Huai's group couldn't help but twitch their lips.
She really didn't try to keep them.
"Would you like to stay for the night?" Yun Xiaoxiao asked with a smile.
Jiang Huai nodded, "If it's convenient, that would be best."
With the sky darkening, traveling at night wasn't very safe.
"It's very convenient."
Yun Xiaoxiao grinned.
"Since we're all familiar, I'll give you a discount. One level one crystal core per person, you have... twelve people, that's twelve crystal cores. Isn't that a great deal?"
Yun Xiaoxiao tilted her little head, looking innocent.
