The king wrote to comfort Hades again, hoping that he would not be bothered by such things at this critical moment.
The future of the empire was in the hands of Hades, not to mention that Hades couldn't distract himself for the sake of the future of the empire.
The king had lowered his attitude again in the letter. One could imagine how important Hades was to him.
As far as Hades knew, the current role of Hades was very important. He must protect Hades's last dignity.
Receiving the king's letter, Hades understood the king's true feelings for him.
He finally showed a smile that he hadn't seen for a long time. Since the king still needed Hades, then Hades had more effect on him.
Nothing was more important than now.
The king wrote in the letter that he had sent envoys many times, which was not reliable at all.
