Transmigrating Into the Foolish Cheng Yaojin of the Tang Dynasty

My name is Cheng Yong. I'm an electrician who was struck by lightning and killed while working at height, then transmigrated into a bloody battlefield in the Tang Dynasty. I became sworn brothers with Li Shimin and Qin Qiong. By acting crazy and foolish, I won everyone's favor, then used modern technology to change the future of the Tang Dynasty. I may be silly, but I'm lucky: pretending to be a fool helped me achieve everything, from wealth and power to the pinnacle of life.
