The prime minister wasn't executed because they're taking into account whatever good things the prime minister had done for this kingdom.
Although the prime minister had done more bad deeds than good ones, they couldn't dismiss the prime minister's service for the past decades.
At the same time, after Kian won the case, the cabinet immediately brought him up as the new prime minister and the youngest one in history.
He wasn't even eleven years old yet when he became the new prime minister, but the commoners accepted this strange event entirely because of Kian's unusual talent.
It was a five-star talent in politics!
Even if he was only a child at the moment, everyone welcomed him as another legend comparable to Duke Fez.
And Kian became the prime minister faster than the one in the storyline.
