Shen Yunzheng, the son of former Ming general Shen Chongwen, carried the family's Qiushui Yanling sword on his back and the soft sword Qinghong at his waist. After being betrayed by traitors in the anti-Qing organization "Fu Ming Hui", he took the seven-year-old orphan Gu Nianzu, the youngest son of former Hanlin scholar Gu Yanwu, on the road to the south. Hidden in the child's arms is the strategy for resisting the Qing Dynasty in the southeast, which is the military intelligence that Zheng Chenggong urgently needs.
Zhang Jing of the Qing Dynasty, Mu Teng'e, led his elite troops to pursue him all the way. Shen Yunzheng held his young son in his arms, crossed the canal, crossed Taihu Lake, crossed Tianmu Mountain, passed Yunshui'an, climbed Xianxia Ridge, and entered Wuyi Mountain. Along the way, he met boatman Zhao Bo, old nun Yuan Jing, tea picking girl A Luo and Hongmen righteous men. Shen Yunzheng used the "Wandering Dragon Eight Swords" and the self-created "Silent Sword" to set up an ambush in Tingjiang River to annihilate the pursuers, and finally escorted Gu Nianzu and Fang Lue to Zheng Chenggong in Xiamen. Mu Teng was executed on his forehead, and Gu Yan was imprisoned in Guangdong.
At the end, Shen Yunzheng headed north to Jianyang. Uncle Zhao's boat was still moored on the shore, and A Luo decided to go with him. The sword is not rusty, the road is not finished, and the bright moon shines on the southern frontier.
