Li Nianfan went back to the four-part architecture and began making some animal feed for the zoo animals. He had plenty of materials at hand. For example, the bones of the game meat could be ground into powder. There were also vegetable scraps, eggshells, expired milk, and more. All these could be fed to the animals instead of being thrown away. Little by little, the four-part architecture had become a self-sustainable ecosystem.
Dragin looked at the busy Li Nianfan and said, "Brother Li, there's no need to go to all this trouble. Just let them be."
Li Nianfan smiled and said, "These foods will make them healthier and it doesn't take much trouble to make them. Besides, they'll be tastier after giving them these."
"You're right. Let me help you, too!" said Dragin.
"Help me grind the hippo's bones into powder," said Li Nianfan.
"Brother Li, Brother Li, let me help you, too!" said Nanan.
"Brother Li, I've come to help, too!" said Little Fox.
