In the story of "Romance of the Three Kingdoms", Zhuge Liang's strategy and layout have always been the focus of attention. Among them, a conflict caused by Zhuge Liang's death has become a bright spot in the story.
Wei Yan was dissatisfied with Yang Yi's command, and bravely stood up and led his troops to confront Yang Yi. However, Zhuge Liang chose Ma Dai and let him shoulder the task of killing Wei Yan. This decision raises doubts, but there are profound reasons.
First of all, Ma Dai's martial arts in the late Shu Han period were relatively strong. Faced with the gradual death of the "Five Tiger Generals", Wei Yan became the strongest general in martial arts. And Ma Dai was born in Xiliang and honed his martial arts since he was a child, so he was the best candidate to kill Wei Yan.
Secondly, Ma Dai followed Ma Chao to join Shu Han, unlike other Western Liang generals. This made it easier for him to gain trust in Wei Yan's eyes, as he was not an enemy of Shu Han before, but a general of Xiliang who had returned halfway.
Third, Ma Dai is bold and careful, not only brave and bold, but also shows a cautious and cautious side. His escape from the killing of Maten shows that he is adept at stealth and self-preservation, making him a perfect fit for the task.
In addition, due to Ma Dai's rebellion against Xiliang, his credit in Shu Han was relatively reduced, but he instead became a force to be reckoned with. This made it easier for him to accept Wei Yan's trust and carry out the slashing mission.
In the end, Ma Dai and Cao Wei had a deep hatred. Ma Dai's uncle and two brothers were both killed by Cao Cao, leaving him devastated. Therefore, Ma Dai would never consider defecting to Cao Wei and becoming the ideal candidate to kill Wei Yan.
To sum up, Zhuge Liang's choice of Ma Dai to take on the task of slashing was not accidental, but the result of careful consideration, taking into account his martial arts, loyalty, and trust in Wei Yan.
