"Sir Aditya, your strength is really admirable. Without you, winning this battle wouldn't have been easy for us." Adian was respecting Aditya even more after witnessing what he was capable of.
"Sir Adian, I can't spend any more time here. I will head to the other two remaining battlefields and help our side win the battle with the least causalities. Sir Adian, I think it would be best if you and your prime minister head back to the Capital." The current Hephaestus Kingdom was extremely unstable. Who knows, the powerful gangs might try to take over the entire Kingdom in the absence of the King. The Kingdom was full of corruption and traitors. The King cannot trust anyone.
And also, Adian isn't that powerful. He is a mage. He can be easily replaced by another Mage. Aditya felt Adian and his Prime Minister wasn't that useful on the battlefield. He was too passive and soft. He can't even control his own army.
