The arrival of the puppet girl made everyone unable to stir up any turmoil. Xu Fei did not issue an order, so she stood directly beside Xu Fei. Although the atmosphere was still as usual, Xu Fei always felt awkward, so she let her enter the space key to store the corpse, which was also possible for her to stay by her brother's side.

I don’t know what Wang Yu’s assistant said to him. When everyone was about to take a nap after lunch, Wang Yu came towards Xu Fei.

"Boss, I'll talk to you about something." Wang Yu was a little hesitant.

"Tell me!" Xu Fei said lightly after lying down.

"We need more experimental products, that is, specimens of living people." Wang Yu said nervously. He knew Xu Fei's principle. Although Xu Fei was cold-blooded, he was treating the enemy. However, the current problem is that more living people need to do experiments.

Xu Fei suddenly became silent, and even the other people who were originally chatting quieted down when they heard Wang Yu's words.

"Whether it is testing the phagocytosis efficiency of the drug or the parasitic mother, it requires the experiment of living people." Wang Yu quickly explained.

When everyone looked at Wang Yu's assistants, they all nodded silently. The assistant named Tang Tian even stood up and walked towards Xu Fei.

"Boss, Brother Yu is right. We have achieved some results now, but if there is no living person, the success rate cannot be tested at all, and everything that follows cannot be carried out." Tang Tian helped Wang Yu explain.

"Is it okay to use animals to replace them?" Xu Fei asked for a moment. Didn't he remember that medical experiments are all made of mice?

"Boss, I know what you are going to say. This kind of experiment must be conducted simultaneously with animals and living people. After all, these agents act on humans, and the genomes of animals and humans are different."

Xu Fei was silent again. He had actually thought of this day, and he still protected the last trace of goodness in his heart, but he also understood that one general had achieved success and ten thousand bones were undone.

Just like an angel and a devil collide, one thought is heaven and one thought is hell.

Such choices and entanglement made Xu Fei feel a little confused. Once he crossed the bottom line in his heart, he would become a completely devil in the future.

The atmosphere in the attic was instantly depressed. Xu Fei thought for a while, and he sighed heavily. This decision should be cautious.

"Let's do this, Wang Yu, you guys do other experiments first, I'll think about this."

"But, boss..."

Tang Tian had to continue to say it, but Wang Yu stopped him. Looking at Xu Fei who was thinking, Wang Yu said, "Well, there is no hurry, we can do other things first."

With a wave of his hand, Wang Yu called his assistants from the high-end laboratory to get off the attic.

"Sister Qian, aren't we going to acquire some professions about pharmacists for the newcomers?" Zhao Jing said.

Wu Qian was stunned, reacted quickly, and said hello to Xu Fei and called everyone out.

Xu Fei just nodded mechanically. After everyone left, he fell into deep thought.

"Brother Yu, the boss must make a decision quickly. The experiment can no longer be carried out." Tang Tian urged.

"Give the boss some time. Many people will die of living specimens. Although the boss is cold-blooded, he is not a person without conscience, so this decision is really hard to make." Wang Yu sighed and said.

"Then we'll be in the afternoon..."

"Let's rest! Anyway, the animals have been used up, and the improved pets cannot be carried out." Wang Yu said lightly.

The assistants following behind were silent for a while. At this moment, they saw Wu Qian and her men also came down.

"Sister Qian, why are you here too?" Wang Yu asked.

"Let Xu Fei be quiet alone, after all, you have to make up your mind to make this decision." Wu Qian said.

"Then where are you going now? Why don't you find a place to sit?"

Wu Qian waved her hand and said, "Let's go to other forces to make a move and acquire some professions like pharmacists, which is just right for you and your assistants to use."

As soon as Wu Qian finished speaking, Tang Tian and others were excited. Seeing that Wu Qian and the others were really going, Wang Yu said anxiously: "Sister Qian, please leave Su Ya for me."

Seeing everyone staring at him, Wang Yu quickly added: "Where are you thinking about your expressions? I just asked Su Ya and I to catch some small animals for experiments."

Wu Qian thought for a while and left Su Ya and Xiaoqing.

"Xiao Hui will follow me this afternoon." Wu Qian said.

Su Ya's arm was wrapped around Xiaoqing and she nodded.

"Zhang Meng, you follow Xiaoya, remember, you must ensure everyone's safety." Zhao Jing said in command.

The women's team happily agreed that they liked the most about catching pets.

"Let's go! Where is the goal?"

After Wu Qian and the others left, Su Ya looked at Wang Yu and asked.

"I don't know." Wang Yu looked confused. Isn't you the best thing to catch pets?

The women's team members were ashamed, and there was no goal at all. Even Wang Yu's assistants couldn't help but cover their faces.

Just as Su Ya was about to have an attack, she saw Wang Yu screaming, and everyone was stunned.

"I got it, catch pets, of course I go to the zoo."

Su Ya rolled her eyes immediately, is this guy a hindsight?

"The zoo has been cleaned up by people from several major forces long ago." Xiaomei said with a wry smile.

Wang Yu thought for a long time, and suddenly a flash of inspiration flashed, and he really thought of a place.

It is a private manor, he has seen it from afar, where there are many animals.

"Let's go, everyone come with me!" Wang Yu didn't explain, and called everyone out of the city village.

Xu Fei had been thinking about it for a long time in the attic. As Wu Qian said, he had to make up his mind to make this decision.

However, once you do this, you are trampling on your only remaining heart. It seems that only holding Bing Xin's necklace in your hand can calm his heart a little.

"Siyu, what do you think I should do?" Xu Fei murmured.

Half an hour later, Xu Fei's eyes were no longer so entangled, so he put away Bing Xin's necklace and went out.

Another half an hour later, he brought back a girl, which he rescued in a building, and all the people who insulted her in that building were ruthlessly slaughtered by the girl.

All that was left on the girl's face was indifference and coldness.

She was standing in front of Xu Fei, waiting quietly. Xu Fei and her already had a life-and-death contract, so she called Xu Fei the master.

"If the mission of Lieye is to dispel this darkness that has no beginning and no end, then I will ask you to go from light to darkness. From then on, you will become a demon and be a killer in the darkness." Xu Fei murmured, as if there was still struggle on his face, and then added: "Do you do what I don't want to do."

"Yes, master." The girl said firmly.

"Your name is Blood Butterfly, and your team will become the real Dark Night Team independent of the Night Hunting."

"Yes, master." After saying that, Xuedie left the city village.

In the evening, everyone came back and saw everyone laughing, they should have gained a lot.

Wang Yu never asked Xu Fei the answer again, and Xu Fei did not answer...
