李四一在家半导体厂干了一辈子的活，从一个普普通通的设备工程师转成了工艺工程师，后面又去干PIE,晚期靠着公司工资还完了房贷，完成了人生几座大山之后，觉得对工资要求没那么高了，干不动了又转成公司HR了。
退休以后李四一又觉得太闲了，又重新返聘成了一个保安，每天坐在空调房里面负责一下厂商换卡的事物就好了。就这样日复一日年复习一年，李四一终于干不动了，彻底告别了半导体厂，在一个平静的日子，李四一就此沉睡了，也走到了人生的终点站。
李四一往生之后，觉得全身轻飘飘的，处于黑暗之中，可李四一并不觉得害怕，他之前遇到过半导体厂停电，全场的灯都灭了，就厂里的绿色安全出口的灯是亮的。
可这里，貌似也没有安全出口的标志。
李四一听到远远的有人喊他，李四一一看，那人全身穿着黑色的老式服装，头上戴着一顶黑色的尖锥帽子，帽子上写的是天下太平，李四一心想这大概就是勾魂使者黑无常，让我去地狱找阎王报道去了。
那人果然是个鬼差，拿着勾魂锁一把就把李四一勾住，带着他就往地府去，他们来到地府的入口，写着一个大大的地府。穿过地府大厅，他们来到了一处电梯，电梯挺大的，有四五个半导体厂机台move in的货梯，关键是四周都是透明的。
黑无常和李四一介绍道，这部电梯，直通地府，中间会经过18层地狱，你可以看到在上面受刑的鬼魂。李四一一看外面，电梯缓慢地下降，李四一透过玻璃能看到外面的景象，有推着机台一直前进的，也有穿着无尘服一直打螺丝的工人，也有被架在火里烧烤，也有被鬼差拔舌头的……惨叫声，哀嚎声不断地从四周涌入李四一的耳朵。
李四一听着怪瘆人，不瘆鬼。李四一被带到了阎王跟前，前面还有挺多排队的黑无常将勾魂锁解开，便让李四一排队去了。李四一看着前面的人，侧耳聆听他们的故事。
正在阎王面前的是一个黑心的资本家，阎王在审判他生前做过的恶事一桩桩，听到了诸如加班不给加班费，白嫖底下员工劳动力之类的东西，阎王感觉很生气，说道，我这边地府节假日加班都三倍，你这个有点小钱的破厂长就敢把工人的加班费给吞了，还按上个调休的名头？牛头马面，给他推到苦力地狱去，让他去推光刻机，推个100年，下辈子投胎做一头牛马。下一个！
下一个鬼看着就不太像好人，阎王问他生前犯了什么错，他回答道，杀人了。阎王在人间的监控调出来了，之间那人开始无差别地砍人，阎王喊道，来人，让他去油炸地狱炸上一千年！接着给他魂飞烟灭，永世不得超生。
总算轮到李四一了，阎王对李四一说，你去奈何桥喝杯孟婆汤，投胎去吧。李四一感到诧异，阎王你不问我什么吗？阎王说道生死薄上写的很清楚，自然死亡，你也没犯什么大错，投胎去吧！
李四一又问阎王，能选择自己投胎的家庭吗？阎王说道，这个不行，公平起见都是随机的，哪里有人出生你就刚好去吧。
李四一和阎王告别了，来到了奈何桥，奈何桥上孟婆正在卖着孟婆汤。孟婆问李四一要什么口味的，李四一要了一杯青柠口味的。
青柠口味的1万冥币，李四一从口袋里掏出一千万冥币说不用找了，他接过孟婆手中的孟婆汤一饮而尽，接着就脑袋一空，往奈何桥的尽头奔去了……
Li Siyi worked in the semiconductor factory for his whole life. He changed from an ordinary equipment engineer to a process engineer, and then to a PIE. In his later years, he paid off his mortgage with the company's salary. After completing several major challenges in life, he felt that he did not require such high salary, and he became a company HR. After retirement, Li Siyi felt that he was too idle, so he was re-employed as a security guard. He just sat in an air-conditioned room every day and was responsible for the card replacement of the manufacturer. After reviewing day after day, year after year, Li Siyi finally could not work anymore and bid farewell to the semiconductor factory completely. On a quiet day, Li Siyi fell asleep and reached the end of his life. After Li Siyi passed away, he felt light all over and in the dark, but Li Siyi did not feel scared. He had encountered a power outage in the semiconductor factory before. All the lights in the factory were off, and only the green safety exit light in the factory was on. But here, there seems to be no sign of a safety exit. Li Siyi heard someone calling him from afar. Li Siyi looked and saw that the man was wearing old-fashioned black clothes and a black pointed hat on his head. On the hat was written "Peace in the World". Li Siyi thought that this was probably the soul-catching messenger Hei Wuchang, who asked me to go to hell to report to the King of Hell. The man was indeed a ghost messenger. He grabbed Li Siyi with a soul-catching lock and took him to the underworld. They came to the entrance of the underworld, which had a big "underworld" written on it. After passing through the hall of the underworld, they came to an elevator. The elevator was quite large, with four or five semiconductor factory machine move-in freight elevators. The key was that it was transparent all around. Hei Wuchang and Li Siyi introduced that this elevator went directly to the underworld, passing through 18 layers of hell in the middle, and you could see the ghosts being tortured on it. Li Siyi looked outside, the elevator slowly descended, Li Siyi could see the scene outside through the glass, there were people pushing machines forward, there were workers wearing dust-free suits screwing, there were people being roasted in the fire, there were people having their tongues pulled out by ghosts... screams and wails kept pouring into Li Siyi's ears from all around. Li Siyi found it creepy, but not spooky. Li Siyi was brought to the King of Hell, there were many people waiting in line in front of him. Hei Wuchang untied the soul-catching lock and asked Li Siyi to line up. Li Siyi looked at the people in front of him and listened to their stories. In front of the King of Hell was a black-hearted capitalist, who was judging the evil deeds he had done in his life. He heard things like not paying overtime pay for overtime work and taking advantage of the labor of his employees for free. The King of Hell felt very angry and said, "Overtime pay in my underworld is triple on holidays, and you, a poor factory manager with a little money, dare to swallow the workers' overtime pay and give them the name of a holiday adjustment?" Ox-headed and horse-faced ghosts, push him to the coolie hell, let him push the photolithography machine for 100 years, and be reborn as an ox or horse in the next life. Next! The next ghost doesn't look like a good person. The King of Hell asked him what mistakes he made in his life. He replied that he killed people. The King of Hell's surveillance in the human world was called up. The man began to chop people indiscriminately. The King of Hell shouted, come on, let him go to the deep-frying hell for a thousand years! Then his soul will be destroyed and he will never be reborn. Finally, it was Li Siyi's turn. The King of Hell said to Li Siyi, go to Naihe Bridge to drink a cup of Mengpo soup and reincarnate. Li Siyi was surprised, King of Hell, don't you ask me something? The King of Hell said that it was clearly written in the Book of Life and Death, natural death, you didn't make any big mistakes, reincarnate! Li Siyi asked the King of Hell again, can you choose the family you reincarnate into? The King of Hell said, this is not possible, for fairness, it is all random, you just go wherever someone is born. Li Siyi said goodbye to the King of Hell and came to Naihe Bridge, where Mengpo was selling Mengpo Soup. Mengpo asked Li Siyi what flavor he wanted, and Li Siyi asked for a cup of lime flavor. The lime flavor cost 10,000 hell coins, and Li Siyi took out a piece of 10,000 hell coins from his pocket and said no need for change. He took the Mengpo soup from Mengpo's hand and drank it all, then his mind went blank and he ran to the end of Naihe Bridge...
