Detailed ww2 german army

First, the 1-12 chapter are a bit long and can make some reader back out but after few chapter the summoning german army began, the summoned army are detailed and show how would a guns in fantasy world would be overwhelming, there atill no army that can compete with the tank except the king(he didnt destroy the tank but he manage to overwhelmed it with pure brute force and some magical shield) and bummel, the only thing i hate is how long is the king arc.
