距今50多年前，一艘来自赛博坦的飞船坠落月球，由此引发了美苏两国的太空竞赛。人类争相登上月球，只为一探飞船残骸中的秘密。时间回到21世纪初，经过几番征战，汽车人终于挫败霸天虎的入侵，继而与人类合作，共同保卫美丽的地球。然而发生在切尔诺贝利的事件却将尘封已久的月球计划重新摆到桌面。为了防止霸天虎找到能量柱为非作歹，擎天柱与战友飞赴月球，更从当年的飞船中救出了汽车人的先代领导者——御天敌。御天敌是能量柱的发明者，将上百根能量柱集合在一起便可制造太空桥，实现物质的瞬间传送。Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:一个即将毕业的大学生，她深信自己会成为一个伟大的诗人，而并不是每天在成人书店工作...香云也意识到自己失言，忙闭嘴。我虽处置了叶麻，但我也清楚，再不管你们，你们就要打我家船队的主意了，就要抢到徽王府抽成保护的船队头上了。Out-of-the-box test.
