Chapter 538: Void iron, with the help of technology

Under the bright sunlight, a few children in tattered clothes were playing on the grass.

They were really too young, and they looked like they were only four or five years old. Their faces were full of childishness.

They were still young and could not follow their parents to explore the ruins with unknown dangers, so they were left outside by their parents and were forbidden from approaching the ruins.

As for their brothers and sisters, they held simple weapons and followed their parents, trying to find items in the ruins that might be exchanged for food.

Tang Zhen slowly walked to the front of the children. He squatted down and stared at one of the children.

"Little guy, can you let me see the thing on your neck?"

This child seemed to be a mixed-blood of the human race and other races. His eyes were wide open, and he looked very cute.
