Otherworld Arms Empire

As the king of an arms empire, Tang Mo unexpectedly perished and transmigrated to a completely different world, where he unexpectedly obtained an Arms King System.

In this backward world, Tang Mo relies on the abilities granted to him by the system to drive the development of the entire world.

After all, the desire for conquest is the driving force behind the progress of civilization, and life has been constantly evolving between attack and defense for millions of years...

So, selling assault rifles to these archers and training knights to be tank crewmen... there's nothing wrong with that, right?
