"No wonder they gave us two barrels of oil," the girl with the knife said, "So they asked us to burn the corpses! They even killed and mutilated their own people. They... are so cruel."
"Sister." Song Qingtian suddenly raised her head and said to her, "Can you do me a favor?"
"What are you busy with?" the girl calmed down, "Sunny day, what do you want to do?"
"Leave it." Looking at the corpse, Song Qingtian said calmly, "I will find the place where the corpse is hidden, and you will create smoke and deal with the aftermath."
The girl took a look at the sky and the situation behind her, and agreed without saying a word.
With no one patrolling at this time, the two of them evaded surveillance, went around to the back door of the research building, and took Professor Yang's body into a small, loosely guarded freezer underground.
"I don't understand." The girl shook her head and looked at Qingtian and asked, "Why are you doing this?"
"I was entrusted by someone," Song Qingtian said, "My family has taught me since I was a child that I must keep my word and never break my word."
The girl thought for a while and asked, "So, is this Professor Yang actually the real purpose of your coming to Black Terror?"
Shaking his head, Song Qingtian said, "No, he was just an ally I made by accident. Unfortunately, before we had time to fulfill our agreement, he was already murdered. The reason why I came here was made clear to you from the beginning.
It’s for my friends.”
"Friend..." The girl was stunned for a moment, lost in thought, and finally looked at her and said quietly, "The person who can be your friend is really lucky."
"What about us?" Song Qingtian suddenly smiled at her, "Sister, you haven't told me your name yet."
"...Huanyan." After hesitating for a long time, the girl finally said, "My surname is Huan and my given name is Yan. I came to Heifan to find my brothers."
"younger brother?"
"Well, I have three younger brothers, triplets, who disappeared at the same time a few months ago. Later I investigated and found out that they were brought here." Huanyan put down her hand and pointed to her chest.
"They are all still very young, only seven years old, and as tall as me. I just don't know why I haven't seen any trace of them since I've been here for so many days."
Song Qingtian looked up at her and chose silence.
In the silence, Huanyan's hopeful face suddenly slumped down, clenched her hands, and there was a shallow and pitiful hope in her eyes, "Qingtian, tell me, are my three younger brothers, like Professor Yang,
Have you been killed by them?"
Qingtian pursed her lips.
Huanyan raised her head fiercely, with hatred in her eyes, "Even if they are killed, I must find the murderer and kill them myself so that my brothers can rest in peace!"
Qingtian nodded and patted her shoulder.
Huanyan shook her head, indicating that it was okay. She adjusted her emotions very quickly.
"Speaking of which..." Song Qingtian turned his face, held his chin with one hand, and whispered to himself, "Professor Yang has been loyal and fearful of them for so many years, how could he kill at will without any movement at all?
I think there must be some reason for this."
"Yes. We can't get close to the main area of the laboratory building until now. Maybe we can find some traces from Professor Yang." Huanyan answered.
"Yeah." Song Qingtian nodded and agreed, "When Professor Yang died, he was wearing an isolation gown. The isolation gown must be disinfected before putting it on every time. People who touched it will leave traces. Why don't we take a look at what Professor Yang was doing
What did he do in the hours before his death? Who did he meet? Or, in other words, understand why he died..."
"How do you see it?" Huan Yan was puzzled, "Where do you see it?"
"In many ways."
Song Qingtian said, her eyes fixed on his palm, "First of all, you can collect fingerprints. The fingerprints left by the people Professor Yang saw and came into contact with during his lifetime."
