Mountains and Rivers Are Recast, and the Sun and Moon Shine Again!

No system, two male protagonists, history, time travel, humor, martial arts, and war! In the first year of Chongzhen in the Ming Dynasty, a young man from the 21st century traveled to the body of Zhu Youjian, who had the same name and surname. "Damn it, this is not the job of the emperor?!" Forget it, since I am here, I will not let the roosters crow for thousands of miles and the bones be exposed in the wild! Huang Taiji, Li Zicheng, you wait! "I will never let you down again in this life!" Sun Chengzong, Sun Chuanting, Zhang Huangyan, Wang Fuzhi, Li Dingguo, Zheng Chenggong... How could so many talents be buried? There may not be any heroes in the world, so who can be more lenient! "Kill the slaves! Let the world return to peace!" "Plain gentry! Let the rivers return to Haiyan!" "Safe to the people! Let the world return to peace!" "Ding Yunei! Let all the nations of China come to court!" (This is my first work, I hope you like it!)
