Emery's sudden appearance at the back of the king's throne immediately alarmed all the knights in the room. They fell into a state of confusion - as to how he was able to move there, and panicked - as he clearly didn't have good intentions.
The knights frantically approached closer towards the king, but stopped when Emery glared at them.
As Expected, King Uther wasn't one of those paper kings, the ruler who could only govern and hide between its bodyguards the moment danger arrived. He is after all a Knight commander of the Divine order.
In an instant, Uther activated the buff ability, [Divine Power], as he drew his sword. Using all the strength that he had, he swung the sword behind him.
Unfortunately, instead of the sight of the sword successfully beheading its target, the same thing that happened to the golden knights earlier also happened to Uther. Emery had grabbed the sword with his bare hands with ease, effectively rendering Uther's counterattack ineffective.
