In the Legend of Luzhen, which episode of Luzhen became Lu Zhao Yi?

Lu Zhen took the new spring clothes of the MC to visit the MC. Du Siyi wants to know why this spring dress is made of hemp instead of silk. After listening to Lu Zhen's explanation, Du Siyi put forward his own idea of sericulture.

Inspired by Du MC, Lu Zhen began to raise wild silkworms and soon showed the brocade made by MC to the emperor. The emperor was very happy and asked Lu Zhen to be responsible for the promotion of wild silk throughout the country. At the same time, the emperor named this brocade Jin Lu. Subsequently, the wild silkworm industry made rapid progress, and the emperor decided to set up a weaving and dyeing department, and appointed Lu Zhencong as the third-grade Zhao Yi.
