Qin Shi Huang Mausoleum - Level 7-4 was the last spin-off level of Qin Shi Huang Mausoleum - Level 7-1 in Plants vs. Zombies Online. There were three pathways. When this level was finished for the first time, the player would get 50 upgrade sun and three Twin Sunflower Puzzle Pieces. To get all three stars, the player had to never have more than 12 plants, and not lose any lawn mowers.
