The Jackalan King opened Kant's letter to him.
Kant's letter was very concise. His condition was that the Jackalan city-state had to hand over 20 tons of crystal ores. If they handed over twenty tons of crystal ores, Kant had to help them deal with the harassment of the undead in the north.
20 tons of crystal ores. This was the number that the Jackalan city-state could reach in two years.
At this moment, the Jackalan King was extremely irascible. He was clearly not interested in Kant's conditions and was even angry.
At such a critical moment, he actually wanted to get some profit from them.
