I'm in the Tang Dynasty Pretending to Be a Magician and Making Electricity

Liu Haitao traveled to the Tang Dynasty and was bound to the cheating "Civilization Jump System". >The novice gift package only contains a bundle of insulating tape and half a copy of "Basics of Electricians". >He bravely deceived Cheng Yaojin: "This is a thunder weapon that can control the lightning of the nine heavens!" >Lao Cheng split the insulating tape with an axe: "Demon Dao, pay me back the money I paid for the fairy mirror!" >Liu Haitao desperately turned the hand-cranked generator, and the light bulb on the top of the Tai Chi Hall turned on strangely. >Li Shimin stood up in response: "Hurry up and install this sacred object for me! I will stay up all night to approve the memorial!" >Liu Haitao looked at the "ultra-high voltage transmission lines" displayed in the mall and fell into deep thought: >——Who should I sell this thing to?
