In the play, Liu Yong seems very incompetent. His main function is to persuade everyone not to worry, and Liu Yong in the play has indeed achieved the realm of Taishan collapse, but his ability to solve crimes is a bit too general.
Liu, the prime minister in history, is definitely a knowledgeable person. He can solve crimes like a god and has the ability to apply the world. He is a proper official.
Looking back at Liu Yong in the play, he gave me the most powerful ability, probably his forbearing kung fu. Even if the witness is killed and his own people are arrested, he will always look confident and calm in the face of all kinds of old foxes in officialdom. Moreover, his reputation is far more intimidating than himself.
But what about the facts? In the play, I feel that he is always waiting for the enemy to make mistakes, and what he has done is really limited. Wu Xu, Souranto, Lido and Zang Haikun in the play are all like this, which should be the biggest slot.
