Du Xixi came to CD-0329 Star to create something more practical.
Currently, Chen Yin has control over sixteen primitive planets, which are the safest environments and most resource-rich primitive planet groups in the All-Star. Perhaps other empires across the interstellar also hold similar primitive planets, but the Blue Star Empire has the lion's share.
Under such advantageous circumstances, it's natural that these primitive planets are not solely used for food production. Developing related industries to generate wealth is the wisest choice!
As for whether these related industries will be "copied and pasted" by those empires also possessing primitive planets, that's not something Chen Yin and his team need to worry about.
While the predecessors enjoy the meat, they always need to leave some meat scraps and broth for the successors. A temporary solo brilliance is fine, but over time, hidden dangers will inevitably arise.
