Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.叶卡捷琳娜正在进行激烈的权力斗争，宣布战争，镇压叛乱……在她的肩上-一个沉重的负担的权力。俄罗斯的命运掌握在她的手中。《母子连心》主要讲述了一对母子二十多年来的情感纠葛——儿找母、母寻子的故事。折射出当今社会一些人在金钱和利益的驱动下失去对社会的责任感、家庭的温暖以及亲人的关爱。跨越50年的时光，喷嚏大魔王和小哈欠回来了！这次他们回来的目的是為了要让小哈欠成為女王，而且居然还要在小甘的孙子身边修行！？為了找寻现代小学生的梦想，小哈欠努力得不得了！可是，小哈欠超爱恶作剧的的弟弟噗太也一起登场，搞得人类世界一团混乱！他们究竟能不能找到梦想呢？讲述在浮游城“艾恩葛朗特”从第一层开始往上攻略的故事,《闪光》和《黑剑士》的相遇故事。Dark Elves: Luxe, Clent, Kakun, Saran, Maya, Sharplon, Morgan of Resentment
