In "Nine Songs of Tianxing", Wei Zhuang killed the Scorpion Gate for several reasons. First of all, the Scorpion Gate is the lackey of the Korean general Ji Wuye, who will do whatever it takes to maintain their power and status for their own selfish interests. As the leader of the quicksand organization, Weizhuang has been committed to overthrowing South Korea** and seeking peace and happiness for the people. Therefore, the existence of the Scorpion Gate is a threat to Wei Zhuang, and he must take action to weaken Ji Wuye's forces and thus advance his revolutionary cause.
Secondly, the scorpion gate plays a disgraceful role in South Korea, they accept bribes, collude with foreign enemies, disrupt the national order, and all kinds of crimes are heinous. As the embodiment of justice, Wei Zhuang naturally cannot tolerate the existence of such a ** force. He chose to kill the members of the Scorpion Gate in order to deter other lawbreakers and maintain the stability and tranquility of the country.
In addition, there is a personal vendetta between Weizhuang and the Scorpion Gate. In the play, the poisonous scorpion gate once poisoned Wei Zhuang's best friend Han Fei, which made Wei Zhuang hate the poisonous scorpion gate to the core.
In the end, Wei Zhuang's killing of the Scorpion Gate was also to safeguard the interests of the Quicksand Organization. The Quicksand Organization is a secret organization with the purpose of justice, and they fight against the best forces to defend justice and truth.
To sum up, there are many reasons why Wei Zhuang killed the Scorpion Gate. He not only wants to avenge his best friend Han Fei, but also weaken the power of South Korea and maintain the stability and tranquility of the country. At the same time, he also has to defend the interests and justice of the Quicksand Organization.
