Charles was very worried about Jonathan's decision to send out those ten plus knights, as Prime Blood Limit's defense was too strong.
You must know, even alchemical explosives couldn't break the Radiant Magic Array, and though the Prime Blood Limit was a bit inferior to the Radiant Magic Array, it couldn't be pierced by the Magic-Breaking Bombshell Bullet either.
But during the South Ceraph Reclamation Army's second siege, Charles still didn't see those ten plus Transcendent Blood Clan members appear on the battlefield.
He completely couldn't understand what Jonathan was thinking by letting these restorers go to their deaths. Could those not be his "brethren"? As long as he moved out of the range of the Anti-Space Sniper Rifle, he no longer needed their protection. Even if there could be dangers on the battlefield, as a commander, couldn't he make a little sacrifice?
Ordinary people sacrifice, and the commander can't take a little risk?
