At the Beginning of the Dark Day, I Was Actually Elder Chang

The system automatically changed the tag in the background. This is not fan fiction. Microcell number + semi-infinite flow + urban power + no CP + micro group portrait Slow pace (a small amount of plot, does not affect reading, even if you have not played Purcell, you can get into it) As a graduate student, Li An successfully got an offer from a big factory. He thought his life would be smooth sailing, but he was so unlucky that he was forced to time travel and became a big truck. The world after traveling is full of crises, such as level-breaking restrictions, spiritual pollution, surveillance by outside gods, and abyssal invasion... The collapse of the world is not uncommon, and every moment someone becomes the firewood that keeps the world moving forward. Fortunately, he still has a system, but why is it called "Big Dark Sky"? Did he really become Elder Chang? Please, he doesn't have the skill "Chang·Diamond Storm"! It is hard to violate destiny, and the world is in a state of flux. It seems that it is time for people in this world to feel the shock of a little "big dark sky".
