The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu在7年前在煤矿深处发现了不明身份的怪物的乡下小镇，疫病的传言流传开来，在心脏病患者新增的过程中，修验道者的年轻人贤一失踪了。贤一是活生生的木乃伊，为了拯救这个世界而进行的终极修行，就变成了神佛。然后，贤一醒过来说：“祓除被妖怪附身的世界。”该剧讲述了被爱的人背叛后，为重新找回自己的人生而展开的复仇活动。
