Li Zhe, a top engineer in the 21st century, accidentally passed through the soul of Jianwen Emperor Zhu Yunwen, and was transported to Nanyang (today's Singapore) by mysterious power at the last moment of the Jingnan Campaign. Relying on modern knowledge, systematic golden fingers, and Chinese orthodox identity, he integrated the Nanyang Chinese forces and established a new regime that combined science and technology with Confucian civilization. He eventually counterattacked the mainland and created a new Ming technology empire.
