        二世元年七月，发闾左適戍渔阳，九百人屯大泽乡。陈胜、吴广皆次当行，为屯长。会天大雨，道不通，度已失期。失期，法皆斩。陈胜、吴广乃谋曰：“今亡亦死，举大计亦死，等死，死国可乎？”陈胜曰：“天下苦秦久矣。吾闻二世少子也，不当立，当立者乃公子扶苏。扶苏以数谏故，上使外将兵。今或闻无罪，二世杀之。百姓多闻其贤，未知其死也。项燕为楚将，数有功，爱士卒，楚人怜之。或以为死，或以为亡。今诚以吾众诈自称公子扶苏、项燕，为天下唱，宜多应者。”吴广以为然。乃行卜。卜者知其指意，曰：“足下事皆成，有功。然足下卜之鬼乎！”陈胜、吴广喜，念鬼，曰：“此教我先威众耳。”乃丹书帛曰“陈胜王”，置人所罾鱼腹中。卒买鱼烹食，得鱼腹中书，固以怪之矣。又间令吴广之次所旁丛祠中，夜篝火，狐鸣呼曰“大楚兴，陈胜王”。卒皆夜惊恐。旦日，卒中往往语，皆指目陈胜。
