他记不太清楚自己是怎样被关进来的,也不知道是什么人囚禁了他。他猜测对方制伏他时打伤了他的头部,让他的记忆有些残缺。囚牢常年光线阴暗,四壁冰冷。最奇怪的是,囚牢没有门,只有一个小洞,每天会有人给他送饭。刚被关进囚牢的时候,他曾研究过出去的方法。他对着冰冷黑暗的铁壁重重地敲击,试图发现什么机关。忽然,他愣住了。他感到墙壁在给他回应。 He did not remember exactly how he was locked in and did not know who imprisoned him. He guessed that the other side wounded him and wounded his head, leaving some memories of his memory. Prisoners year-round dark light, cold walls. The weirdest thing is that there is no door in the prison, there is only one small hole and someone will be given daily meals. At the time of his custody, he had studied ways to go out. He struck heavily against the cold, dark iron wall, trying to find out what the organ was. Suddenly, he stared. He felt the wall give him a response.
