Hui Yue sat down, and the children immediately gathered around him. "Can we stay here for a few days?" he politely asked. The children nodded with such intensity that it caused laughter to escape from all the elderly individuals present.
"I'll tell you about the outside world," Deng Wu said as he also sat down. His words made all the children gathered around Hui Yue immediately shift over to Deng Wu.
As he began to describe the world he came from in detail, a faint smile appeared on his face.
