"These guys are willing to do anything to gain power, so you can do whatever you want."

Zhou Xu nodded and began preparing for the injection.

Looking at the box of injection solution on the table, he suddenly thought of the energy released by the white monkey.

Zhou Xu looked at the refugees again, thinking that perhaps these people could still be of other use.

Thinking of this, he calmly took out another box of black injection fluid.

After injecting this special liquid into the bodies of the awakened refugees, Zhou Xu deliberately explained:

"The drug has been administered, but superpowers can't be upgraded in a day or two. You'll have to wait a few more days."

The refugees breathed a sigh of relief upon hearing that it was only a matter of time.

“We can wait for years, why not launch it in these few days?”

In the laboratory corridor, the joy on the faces of the refugees had not yet faded; they were filled with anticipation for the power they were about to gain.

One of the refugees, his face filled with hope for the future, made a promise to Zhou Xu:

"Don't worry, even though it's free, we'll definitely come back to thank you after our abilities are upgraded."

"Back?" Lu Yuefei stood to the side, a meaningful smile playing on his lips.

Zhou Xu then quietly handed a small bottle filled with a clear liquid to Lu Yuefei.

Lu Yuefei took the bottle, his excitement barely concealed. He carefully packed it away, which was the real reason he had brought the person over.

Zhou Xu pointed to one of the iron gates in front of the laboratory, then turned to the group of refugees and said:

"You will need to be observed for a period of time after the injection. Please go to the room in front and wait for a while."

His voice was calm, but a complex emotion flashed in his eyes as he looked at the refugees.
