While Ernst commanded the front lines, Constantine took on the role of a strategic tool at the rear. Enriching the East African industry has always been a pursuit of Ernst's, and agriculture, as East Africa's dominant industry, is of utmost importance. Currently, East Africa's agricultural products that have achieved large-scale cultivation and massive exports are few, including sisal, cloves, and pyrethrum, with sisal consistently topping the export list of tropical economic crops in East Africa.
However, these few economic crops are still considered niche or uncommon. The promotion of pyrethrum, in particular, is closely linked to the insect-repellent products launched by the Heixinggen Daily Necessities Company. Local East African efforts to cultivate pyrethrum significantly contribute to preventing disease transmission by mosquitoes in East Africa.
