That Old Wei Zhongxian, How Did He Become the Grand Ancestor's Sworn Brother?

A soul from the future transmigrates to the end of the Ming dynasty and becomes Wei Zhongxian, the “Nine-Thousand-Year-Old.” He discovers that he can travel through certain periods of time. How could that not be insanely awesome? On his first trip back to the Hongwu era, he uses some “high-tech tricks” to win over Zhu Yuanzhang, who accepts him as a sworn elder brother. When Wei Zhongxian appears before Chongzhen with the founding emperor and a host of past emperors, Zhu Youjian is so shocked his CPU nearly burns out. Maybe he doesn’t recognize the Emperor Taizu, but how could he not recognize his own imperial grandfather and elder brother? Old Zhu: “You little bastard, were you planning to go after my elder brother? I’ll have you executed!” Wanli: “You foolish grandson, the ‘Prince of the Mountain’ is the elder brother of Emperor Taizu, our own ancestor! To see him is to see Emperor Taizu himself!” Tianqi: “My younger brother, remember this: He is the most trustworthy and indispensable person among the descendants of the Zhu family! As long as he is here, the Great Ming will stand!” Zhu Youjian finally loses it. o(╥﹏╥)o This old geezer isn’t the “Nine-Thousand-Year-Old” at all. He’s a freaking “Ninety-Thousand-Year-Old”!
