I Was a Hero in Jingkang, Northern Song Dynasty

Others traveled through time and brought the God of Killing system, killing people and setting fires to upgrades; I traveled through time and brought the Holy Mother system, saving people from suffering and going to jail! The system forces me to rescue Jin Bing? After saving me, smash the golden camp with one punch! Is the system forcing me to protect corrupt officials? After protecting him, I will break three of his legs! The system forces me to pardon the traitor? After pardoning, I will send him to see the King of Hell! On the first day of the first lunar month of the first year of Jingkang, Bianjing was still prosperous. No one knew that a year later this place would become a hell on earth. Social animal Cheng Xin came through time with the bug martial arts passed down by Jin Yong's heroes. In his left hand, he held the Tianxiang Intermittent Glue, which could restore blood instantly, and in his right hand, he held a wild ball punch that could kill people instantly. Does the system want him to be a saint who can save all sentient beings? He wants to be the king of hell who wants to take revenge. First save the golden soldiers, then kill the commander; first protect the corrupt officials, then confiscate the property; first pardon the traitors, then behead them. At the moment when the Jin Army's iron hoofs broke through the Yellow River, Cheng Xin stood at the top of Bianjing City and slowly raised his fist to the civil and military officials of the Manchu Dynasty: "You want to surrender? First ask me if I will accept this punch."
