An Zhe was stunned because he knew what Lu Feng meant. In 10 hours, Sinan would transform from a human child to an irrational monster. An Zhe tried to communicate with Sinan a bit more and shouted his name. However, Sinan’s eyes stayed focused on Lu Feng and didn’t move. Lu Feng stared back.

Sinan opened his mouth. It was a child’s tender voice but the words were spat out in a cold tone. “You will all die.”

Lu Feng smiled. He took the communication device from An Zhe and declared, “No one will die. Humans will live.”

After saying that, he hung up and turned away. An Zhe made a comparison. When it came to a cold expression and tone of voice, the colonel was better.

Some researchers took over the handling of Sinan and the partition door rose. The doctor declared, “The child is weird.”

Lu Feng suggested, “I’ll come someone in to question him.”

“Thank you for the effort.”

At this time, the wind sound was once again heard in An Zhe’s ears. He looked around and found a similarly hidden round hole at the junction of the ceiling and the wall.

“Lu Feng.” An Zhe gently pulled at Lu Feng’s sleeve. “What is that?”

Lu Feng followed his gaze to the ceiling. “The vents.”

An Zhe blinked.

“You haven’t seen it before?” The doctor wondered. “The outer city doesn’t have it because it was built later.”

The doctor was always willing to explain things to people to An Zhe continued to ask, “What does it do?”

“Supply air.” The doctor’s answer was very simple and then he explained, “The magnetic field hadn’t completely disappeared when the main city was built and the industrial capacity of human beings was still at its peak. In order to build a base that can resist cosmic radiation and solar wind to the greatest extent, the walls of all buildings are four or five times thicker than ordinary buildings and the materials are special materials. It is totally enclosed and the ventilation system provides clean air.”

“The main city can survive and the ventilation system is at least first-class.” The doctor smiled. “Once the artificial magnetic poles were built, various variations began. Before the disperser was invented, the insects were everywhere. In the main city, a three-layered filtration and strangulation system was added to the ventilation system to ensure that no insects could contaminate the air supply.”

“So no matter what, as long as we control the city gates, the main city is absolutely safe.” He tapped out an email on the computer while talking to himself, “Why is there an infection? It doesn’t make sense at all. In addition, the other children in Eden are fine.”

Then his eyes shifted to Lu Feng. “I heard that a girl escaped from Eden yesterday.”

“I asked. The girl is fine.”
