Xu Nian listened, startled, and when she was truly heartbroken, she would bite her lip and shed tears.
Xu Qian patiently comforted her. Before, she had only one relative in this world; now she had Tang Xin.
She wanted to protect both of them well.
"I gave birth to a daughter."
Xu Nian's mouth dropped open. Sister actually had a baby?
She was going to be an aunt?
"Where is the child?"
"Her father is taking care of her. I'll bring you to see her when I have time."
Xu Nian froze and scratched her head.
Her sister had clearly explained the events of the past few years. She had many men, so whose child was it?
"The one surnamed Tang?"
After all, this was the Tang base.
"Not the biological father."
Xu Nian's eyes widened like mirrors. The child wasn't his biological child, yet he was still taking care of her?
How pathetic.
She told Xu Nian many, many things, but deliberately skipped the part about Song Xiaoping.
That was a past she didn't want to recall.
"You can guess when you meet them later."
Xu Nian's eyes lit up. Could it be...
Sister didn't know whose child it was either?
That was interesting.
Xu Nian was a seasoned novel fan and had strong adaptability. Her sister was so beautiful, and in this apocalypse where men outnumbered women, having ten or eight partners wouldn't even be considered a lot.
She opened her mouth, wanting to continue chatting.
Suddenly, there was a knock on the door.
"Knock, knock, knock—"
It was very urgent.
"A Qian, A Qian."
Xu Nian's eyes sparkled with excitement. "Brother-in-law?"
Xu Qian: "...Mm."
Barely considered one?
"Come in."
Tang Zhiyuan rushed in excitedly, his face flushed with enthusiasm.
"A Qian, your blood is the key! It's of great help in decomposing the zombie virus!"
"Brother-in-law?"
Tang Zhiyuan paused and looked at the woman beside him. She looked very similar to Xu Qian, just with a rounder face, leaning towards cute.
"This is... Xu Nian?"
Xu Nian's eyes flickered, and she immediately guessed that this was the research fanatic her sister had mentioned, Tang Zhiyuan.
"Hello, Brother-in-law."
Tang Zhiyuan nodded, then pulled Xu Qian aside.
There was progress with the new vaccine, and Xu Qian was even happier than Tang Zhiyuan.
"What's going on?"
Tang Zhiyuan rattled off a string of professional terms. Xu Qian didn't understand, but as long as her blood was needed for research, that was fine.
"Alright, draw as much as you want. I'll cooperate."
As long as the new vaccine could succeed, she wouldn't hesitate.
"I'll arrange for Xiao Nian, then I'll come to the research building."
"Okay."
Tang Zhiyuan didn't waste words. After finishing the important matter, he ran off without a moment's hesitation.
"Sister, no wonder you said he's a research fanatic. He doesn't even care about his sister-in-law."
"He's always like this. He's fine normally. Let's go, I'll take you to find Fia. She'll show you around properly."
"Mm!"
Xu Nian's eyes twinkled. She really wanted to experience the apocalyptic world.
After Xu Qian handed her over to Fia, she returned to the research building.
[System, why is my blood helpful to the zombie virus?]
[Ding, due to time constraints, the system has combined data and added experimental fluid to your blood, which can accelerate the research speed of the new vaccine.]
Xu Qian: ...
[Ding, your body has been modified by the system and possesses a half-zombie physique. You even took the fertility vaccine and successfully reproduced. You are more receptive to the experimental fluid and won't die easily. Host, please rest assured.]
Xu Qian: ...Fine, as long as I don't die.
As soon as Xu Qian entered the research building, she found it strange. It was empty. Where had everyone gone?
She looked around and found them gathered for a meeting.
"...The successful development of the vaccine is inseparable from the efforts of everyone present. Now, everyone concentrate on the new vaccine! We will not stop until we succeed."
"Yes!"
