With the boost of the economic crisis, East Africa welcomed a rare wave of immigration. In East Africa, "immigration wave" specifically referred to German immigrants, not immigrants from elsewhere. If East Africa truly opened its immigration policies, its population growth rate would become terrifying.
Thus, in 1874, East Africa once again went against the grain, further raising the threshold for immigration and tightening health screenings for immigrants. Health screening was not to be underestimated. This measure alone could filter out a large number of immigrants who did not meet Ernst's expectations.
The nineteenth century had been an age where darkness and development coexisted.

Drugs had not been seen as a problem then; they had been an ordinary part of life.
Ernst had been able to feel this during his previous life in Africa. The state of life among Africans had not actually differed much from that in regions outside Europe and America during the modern era.
Drug addicts could be found on the streets of Africa, in almost every African city. And unlike Americans, who cared about high-tech production or imports from Mexico, they would inhale anything from cough syrup and glue to aviation fuel.
The nineteenth century had none of those dazzling tricks. Opium and chemical drugs simply ran rampant, and without any regulatory system, ordinary people could buy them with ease.
Therefore, once East Africa tightened its health screenings, it could immediately filter out twenty percent of immigrants. Of course, drugs were not the only issue; other criteria were included as well.
In reality, anyone in Ernst's position would have felt frightened by the explosive growth in
