The King has a bow and arrow.
He understands exactly how they work, having made them in his youth as part of his training.
The King has a stealth aircraft with a nuclear bomb.

The King has a hypersonic drone swarm.
He understands the abstraction, but AI designed most of it. AI created new materials, generated the airframe, wrote the software, and controls the swarm in flight. The AI explains the project to the King in high level abstractions.
The King has a mass-phase inhibitor cell.
He kind of... maybe knows some of the words in the abstraction. He is told by the AI he will need to spend about 2 hours in order to understand how to use it. It is based on concept eeaf7aa9d8b6ddca which forces widespread antimatter annihilation that generates a bubble of ionizing radiation causing muons within its radius to... wait, sorry this is irrelevant now because...
The King has a 9fe8fedc4391c064.
It uses 3514a173ef0ecd73 which I am not sure how to explain to you without you first knowing about 67ca42582c291683 which is something like d08352eb9f7ebb4a combined with 455b7127b7bc6f74... ah but wait, this was all far surpassed before I even got the first word out because...
